Exploration and Development Properties

Amisk, Saskatchewan, Canada (Exploration)

The Amisk property, an exploration property, is 39,880 hectares (and 126 claims) with extensive Proterozoic-volcano-sedimentary rock assemblages that are prospective for gold-silver epithermal, gold-rich volcanogenic massive sulfide, and orogenic gold deposits. The property is located in northern Saskatchewan, Canada, centered at approximately 54°42’ North latitude and 102°15’ West longitude.

Amisk lies at the southwest exposed end of the Flin Flon Greenstone Belt, the southernmost exposure of the Trans-Hudson Orogeny. The Amisk gold deposit is hosted within the Amisk and Missi Groups rocks. In 2025, a total of 8 drillholes for a total of 1,806 meters were completed. To date, 330 drillholes for 60,009 meters have been completed in the Amisk property area. SSR Mining holds a 100% interest in the property.

Hod Maden Project, Artvin, Türkiye

The Hod Maden Project (the “Project”), a development property, is 100% owned by Turkish company Artmin Madencilik (“Artmin”), which is jointly owned by SSR Mining, Royal Gold Limited (“Royal Gold”), and Lidya Madencilik Sanayi ve Ticaret A.Ş (“Lidya Mines”). SSR Mining currently holds a 10% interest in the Project. SSR Mining has the option to acquire an additional 30% interest in Artmin from Lidya Mines for $120.0 million in structured payments tied to the completion of project construction spending milestones. SSR Mining serves as the Project operator.

The Project is envisioned as an underground mining operation using drift and fill (“DAF”) and long hole stoping (“LHS”) mining methods. The processing facility (the “Process Plant”) will have a throughput capacity of 800,000 dry metric tonnes per annum (“tpa”) of run-of-mine (“ROM”) ore. The Process Plant incorporates crushing, grinding, and flotation to produce a single gold-copper concentrate that will be transported off-site for further processing.

Hod Maden is located in Artvin Province, 130 kilometers northeast of Erzurum in northeastern Türkiye. The Project is centered at approximately 41.032° North latitude and 41.867°′ East longitude. The Project is accessible by road from both Artvin and Erzurum, with some partially paved roads leading to the Project site.

The Hod Maden property consists of two Turkish operating licenses 87288 and 88657, comprising a total land area of 3,543.24 hectares. The licenses are 100% owned by Artmin.

History

Mining at Hod Maden is believed to pre-date the rise of the Ottoman Empire (14th Century). The Hod Mines, which are mostly in the southern part of the current concessions of the Hod Maden property, were exploited from 1888 to 1904.

The mine site was acquired by the General Directorate of Mineral Research and Exploration (MTA) in 1942. The tenements were explored by various companies up until 2014.

Mariana Resources Limited (“MARL”) acquired AMG Mineral Madencilik A.Ş. in January 2015. Artmin was formed in January 2016, as a jointly owned company, upon the signing of the Shareholder Agreement between MARL and Lidya Mines. In July 2017, Sandstorm Gold Limited acquired MARL and its 30% interest in Project. Royal Gold acquired Sandstorm on October 9, 2025.

SSR Mining entered into a joint venture agreement on May 8, 2023, through which SSR Mining can earn-in to own up to 40% of the Project. SSR Mining currently owns 10% of the Project and has the option to acquire an additional 30% interest in Artmin from Lidya Mines for $120.0 million in structured payments tied to the completion of project construction spending milestones. SSR Mining serves as the project operator.

The Artvin mineral district is part of the Eastern Pontides magmatic belt. The magmatic-hydrothermal mineral deposits and occurrences of the Artvin district are clustered into three main groups: the Hod Gold Corridor, the Kaçkar batholith, and the volcanogenic massive sulfide (“VMS”) bimodal-felsic Cu-Zn belt.

The Hod Maden deposit, lies within the Hod Gold Corridor and comprises three zones: the Main Zone, the South Zone, and approximately 1 kilometer further to the south, the Russian Zone.

The Main Zone extends approximately 150 meters along strike at surface, has a true thickness of up to 70 meters and a down-dip extension of approximately 400 meters, and contains most of the high-grade gold and copper mineralization. Two phases of mineralization are dominant in the main zone: i) multiphase quartz-sulfide (pyrite+chalcopyrite) veining ± hematite+jasper breccia bodies; and ii) semi-massive to massive sulfides (pyrite+chalcopyrite) and gold mineralization.

The adjacent South Zone, measuring approximately 500 meters along strike and 300 meters in depth, is mineralogically and structurally distinct. The South Zone is characterized by quartz-sulfide stockwork veins that host Au and Cu mineralization. Mineralization at Hod Maden is zoned with an inner Au-Cu-Mo association and an outer Zn-Pb-As signature.

The Russian Zone is located 1 kilometer south of the Main Zone, and mineralization occurs over approximately 100 meters of the strike length. The Russian Zone has remnants of early 20th-century Russian mining activity focused on high-grade copper polymetallic veins.

The mineralization model for Hod Maden is debated and theories include a structurally controlled epithermal system, a hybrid VMS-epithermal system, or a syn-volcanic VMS overprinted by epithermal veins.

The Hod Maden deposit will be mined entirely using underground mining techniques. The underground mine will be divided into two distinct mining zones with a modified DAF underground mining technique applied to the Poor Ground Zone (“PGZ”) above the 780 meters above sea level (“masl”, the “780 level”) and LHS applied to the more competent ground conditions below the 780 level. The bulk of the mineralization is located below the 780 level, however, gold and copper grades are highest above the 780 level, reducing with deposit depth.

The underground mine will be accessed through a single portal west of the deposit with secondary egress and fresh air intake in close proximity. The primary exhaust and vertical shaft development are located in the southwest of the deposit.

LHS will use electric-hydraulic jumbos for excavation and ground support with diesel powered load haul dump (“LHD”) units and articulated dump trucks for material handling. DAF mining will utilize excavators and rotary cutters for excavation and front-end loaders (“FEL”), LHDs, and trucks for material handling.

Ore will be trucked to the surface ROM pad located approximately 500 meters from the portal in the South Valley. Waste rock will be trucked to a temporary waste rock dump near the portal from where it will be rehandled to a permanent waste dump facility (“WDF”) through an access tunnel to the Saliçor (North) Valley.

The Project's infrastructure development includes the following:

•Improvements to access roads

•New power supply system

•Processing facilities and associated infrastructure

•Accommodation camp and associated facilities

•Surface mining infrastructure

•Water management system including water diversion, channels, and ponds

•Tailings storage facility (“TSF”)

•Waste dump facility (“WDF”)

Access roads from Artvin are in good condition. A new 154 kilovolt (“kV”) substation with step down to 11 kV will connect the Project to the existing high-voltage network, ensuring a reliable power supply through an extensive distribution system.

The Project emphasizes effective surface water management, focusing on minimizing contact water volumes through diversion and treatment systems. Continuous updates to the site-wide water balance model and an integrated management plan will ensure regulatory compliance and environmental integrity.

Tailings management at the Hod Maden mine will adhere to Canadian Dam Association (“CDA”) Dam Safety Guidelines, with a phased downstream construction approach for the TSF. The facility's design incorporates a composite liner system and zoned filter design to contain hazardous Class I tailings, accommodating a total capacity of up to 4.82 million cubic metre (“Mm³”) assuming construction of the TSF to the 1,353 masl final elevation and considering 1 meter of freeboard and the anticipated depositional slope of the tailings. Comprehensive geotechnical investigations and geological hazard assessments have been conducted to ensure understanding of the storage basin and embankment foundation conditions, while ongoing monitoring and mitigation will manage localized risks during operations.

The WDF is designed to handle PAG waste rock from underground mining. The selected Saliçor Valley site presents advantages that mitigate associated risks, while ongoing geotechnical assessments and a focus on a “design for closure” approach will ensure environmental protection and stability throughout the facility's lifecycle.

Metallurgical recoveries were determined from historical test and 2024 locked cycle tests results, these were used to establish grade versus recovery curves for copper, gold, and mass pull. These equations were used to calculate concentrate production over the life of mine. The average gold and copper recoveries are calculated as 87.0% and 97.0%, respectively.

The processing plant will incorporate crushing, grinding, and flotation to produce a gold concentrate at average grades over the LOM of approximately 22.0% copper and 113 g/t gold. The design capacity is 800,000 dry metric tonnes per year.

The basic flow of processing is summarized as:

•Primary ore crushing of ROM to produce a crusher product size of 80% passing (“P 80”) 56 millimeter (“mm”)

•Primary milling in closed circuit with hydrocyclones to produce P 80 passing 106 micron “µm” grind size

•Flotation of the primary ground ore to generate a rougher concentrate. The rougher concentrate is directed to the Regrind Circuit. The rougher flotation tailings are directed to the Secondary Grinding Circuit

•Secondary grinding of the rougher flotation tail occurs in a variable speed stirred mill in closed circuit with hydrocyclones to produce P 80 passing 38 µm grind size. Secondary grinding of the rougher tail improves the liberation and recovery of gold

•The material of the secondary grind then enters the scavenger circuit. Recovered scavenger concentrate is cleaned in the scavenger cleaner flotation. The cleaned scavenger concentrate is directed to the cleaner flotation circuit. The scavenger tailings, low in sulfidic material is directed to the low sulfide tailings thickener

•A concentrate regrind mill in closed circuit with hydrocyclones to produce P 80 passing 30 µm grind size

•A cleaner flotation circuit, comprising a cleaner conditioning tank with two stages of cleaning and a cleaner scavenger stage. The rougher and cleaner scavenger concentrates are directed to the cleaner flotation circuit. The cleaner scavenger concentrate is recirculated to the cleaner conditioning tank

•Concentrate thickening, filtration and loadout

•Sulfide tailings thickening and disposal to the tailings storage facility

•Low sulfide tailings thickening, filtration and paste backfill

The entirety of the scavenger tailings will be used for the production of paste. After thickening, the paste plant will filter a portion of the tails to meet the target paste concentration of 68.5% solids (by weight) after addition of a dry binder.

Operating Assets

Çöpler, Erzincan Province, Türkiye

As previously disclosed, all operations at Çöpler have ceased following the Çöpler Incident and we are unable to determine at this time when operations at Çöpler will resume, if at all. Additionally, we have not determined that, if we resume operations at Çöpler, the information presented below, including the mineral resources and reserves presented under “Resource and Reserve Estimates”, continues to be accurate or will be accurate at such time as the Company resumes operations at Çöpler. At this time, the Qualified Persons for the Çöpler TRS, as defined under S-K 1300 and NI 43-101, are of the opinion that there are no material changes to the Mineral Resources and Mineral Reserves described herein as compared to the information presented in the Çöpler TRS, other than the permanent decommissioning of the heap leach facility and the determination that heap leach processing will no longer take place at Çöpler. The following information is presented as of February 13, 2024.

Çöpler consists of mining licenses covering mineral resources on the Çöpler, Greater Çakmaktepe (Çakmaktepe and Çakmaktepe extension), and Bayramdere deposits, mineral reserves on the Çöpler and Greater Çakmaktepe deposits, oxide and sulfide processing facilities, and supporting infrastructure. Çöpler is wholly owned by Anagold Madencilik Sanayi ve Ticaret Anonim Şirketi (“Anagold”). SSR Mining controls 80% of the shares of Anagold through a joint venture; Lidya Mines controls 18.5%; and a bank wholly‑owned by Çalık Holdings A.Ş. holds the remaining 1.5%. Greater Çakmaktepe is wholly owned by Kartaltepe Madencilik Sanayi ve Ticaret Anonim Şirketi (“Kartaltepe”). SSR Mining controls 80% of the shares of Kartaltepe and Lidya Mines holds the remaining 20%. The Kartaltepe license includes Çakmaktepe, Çakmaktepe Extension, Bayramdere, and the Mavialtin Porphyry Belt. SSR Mining is the operator of both Anagold and Kartaltepe. All of the processing facilities and operating assets are located on land owned by Anagold. In total, 80% of the Mineral Resources and 80% of the Mineral Reserves of Çöpler are owned by SSR Mining.

The total cost of Çöpler’s gross mineral properties, plant, and equipment as of December 31, 2025 was $2,841.9 million.

Çöpler is located in east central Türkiye, 120 kilometers west of the city of Erzincan, in Erzincan Province, 550 kilometers east of Türkiye’s capital city, Ankara. The nearest urban center, İliç, is located approximately 6 kilometers northeast of the Çöpler mine. The property is centered at approximately 39°26’ North latitude and 38°32’ East longitude and has an approximate elevation of 1,160 meters above sea level. Çöpler is accessed from the main paved highway between Erzincan and Kemaliye and is serviced by both road and rail networks. Mining operations are conducted year-round.

The Çöpler mining operations fall within the license areas numbered 847, 49729, and 20067313, which have been granted by the General Directorate of Mining and Petroleum Affairs within Türkiye. The Greater Çakmaktepe mining operation is located six kilometers east of the Çöpler pit and 1.5 kilometers south of İliç. The Greater Çakmaktepe pits are located within Kartaltepe License 1054 and Anagold Licenses 49729 and 20067313. Ore mined at Greater Çakmaktepe is hauled and treated at the Çöpler facilities.

Anagold holds mineral title and the exclusive right to engage in mining activities within the Çöpler property area. Anagold holds six granted licenses covering a combined area of approximately 16,600 hectares. Kartaltepe holds six licenses covering approximately 7,250 hectares. The total near-mine tenement package is approximately 23,850 hectares.

Kartaltepe sells Anagold ore from Çakmaktepe at an agreed rate. SSR Mining holds a 2% net smelter return (“NSR”) on the Kartaltepe licenses, receivable after repayment of a historical royalty pre-payment.

Under Turkish Mining Law, the royalty rate for precious metals is variable and tied to metal prices. Çöpler is subject to a mineral production royalty that is based on a sliding scale to gold price and is payable to the Turkish government. In September 2020, a presidential decree was issued, increasing the prescribed royalty rates by 25%. As Çöpler produces its gold doré on-site, it is eligible for a 40% reduction to the royalty rate, an incentive offered to process ore locally.

History

The Çöpler region has been subject to gold and silver mining dating back to Roman times. The Turkish Geological Survey in the early 1960s conducted regional geological mapping.

In 2000, Anatolia Minerals Development Ltd (“Anatolia”) transferred the licenses from another company that included Çöpler basin. In August 2009, a joint venture agreement between Anatolia and Lidya Mines was executed. In February 2011, Anatolia merged with Avoca Resources Limited, an Australian company, to form Alacer Gold Corp., which further merged with SSR Mining in September 2020.

Çöpler is located near the northern margin of a collision zone between the Pontide Belt/North Anatolian Fault, the Arabian Plate, and the East Anatolian Fault.

The Çöpler district deposits (Çöpler, Greater Çakmaktepe, and Bayramdere) are best classified as epithermal, disseminated, and skarn deposits related to porphyry copper-gold systems. Mineralizing fluids, derived from the intrusions, were primarily controlled by structural fluid pathways and lithology, including traps controlled by lithological contacts, resulting in replacement, vein and stockwork mineralization.

The deposits at Çöpler occur within fault and shear structures, at contacts between intrusions and marble, as disseminated bodies outboard of contact zones, and as gossans.

Mining operations at Çöpler and Greater Çakmaktepe are carried out by a mining contractor and managed by Anagold. The mining method is a conventional open pit method with drill and blast, utilizing excavators and trucks operating on bench heights of 5 meters. The mining contractor provides operators, line supervisors, equipment, and ancillary facilities required for the mining operation. Anagold provides management, technical, mine planning, engineering, and grade control functions for the operation.

The facility infrastructure currently supports the mine, now decommissioned oxide heap leach, and sulfide plant processing facilities. A pre-feasibility level study for a grind-leach circuit, which would aid in increasing gold recovery from oxide ore, was completed during 2023 and is expected to add to the facilities on site. Prior to the Çöpler Incident, the current leach pad consisted of four phases designed to accommodate approximately 63 million tonnes of oxide ore with a nominal maximum heap height of 100 meters above the pad liner, with additional phases in development. Post Çöpler Incident, the heap leach is now being re-contoured, working towards final closure.

The tailings storage facility is developed and constructed in stages with ongoing work to ensure sufficient long-term capacity for storage of tailings. The flotation plant has been in operation for 3 years and increased the solids content and improved the final settled density based on an increase in the rate of tailings consolidation.

The power supply for the Çöpler mine and processing facilities is provided via a 154 kV transmission line to site. The current Çöpler workforce totals 468 employees.

Operation of the Çöpler mining and processing facilities and mining at Greater Çakmaktepe, have been investigated and authorized by means of a series of Environmental Impact Assessments (“EIAs”). As previously disclosed, in November 2023, prior to the Çöpler Incident, a legal challenge was filed in a local court against the 2021 EIA. On August 9, 2024, the local court issued a decision cancelling the 2021 EIA due to insufficiencies in the 2021 EIA approval process. The Turkish Ministry of Environment, Urbanization and Climate Change, who had originally approved the 2021 EIA, filed an appeal of the decision, and the Company filed a simultaneous intervener appeal. With the appeal court cancellation of the 2021 EIA in January 2025, the operating guidelines at Çöpler revert to those outlined in the Company’s prior EIA, the 2014 EIA. The 2014 EIA permitted Çöpler boundary incorporates 1,686 hectares, whereas the 2021 EIA permitted Çöpler boundary incorporates 1,747 hectares. The Company is currently in the process of an integrated EIA study covering Çöpler and Çakmaktepe to allow ongoing development of the operation for the next several years.

Oxide Testwork

The heap leaching facilities were commissioned at the Çöpler mine site in late-2010. The heap leaching facilities and related equipment and operations were principally impacted by the Çöpler Incident, and the heap leach facility is in the process of being decommissioned following the Çöpler Incident.

Sulfide Testwork

The sulfide process plant commenced commissioning in the fourth quarter of 2018. The plant consists principally of a pressure oxidation (“POX”) leach followed by a cyanide leach to recover gold. The sulfide process plant was not impacted by the Çöpler Incident. The facilities are operational, but have been suspended.

The current determination of POX gold recovery is based on assessment of results for the pilot testwork programs undertaken prior to commencement of operations and benchmarked with the existing operating data. An equation has been derived to calculate gold recovery by material type for all ore that is subject to POX; this includes direct POX feed and flotation concentrate. The Reserve Case average sulfide gold recovery is 91.0%.

Grind-Leach Testwork

In support of the Çöpler Expansion project, testwork was commissioned in 2023 to better understand the benefit of conventionally milling the oxide resource existing at the Çakmaktepe Extension. ALS Kamloops completed direct cyanidation testing by standard cyanide bottle roll tests of four variability samples and a jasperoid sulfide master composite. The leach feed grind size target was a P 80 of 75 µm. Gold recovery ranged from 60% to 90% depending upon lithology with the jasperoid material exhibiting slight refractory characteristics at the lower end of the reported range.

The Company, pending restart approval, can operate the sulfide process plant. The heap leach facility is in the process of being decommissioned following the Çöpler Incident.

The basic flow of processing through the sulfide plant is as follows:

The incorporation of a flotation circuit into the existing sulfide plant to upgrade sulfide sulfur to fully utilize grinding and POX autoclave capacity was constructed and commenced ore production at the end of January 2022. This addition to the sulfide plant is incorporated between grinding and acidulation by taking a bleed/slip stream from the grinding thickener feed, floating sulfides, and returning the sulfide concentrate to the grinding thickener to be combined with direct autoclave feed. Gold in the flotation tails (i.e., not recovered to the flotation concentrate) is combined with the material that was processed through the POX autoclave circuit; this combined stream then goes to the gold leaching and recovery circuits for gold recovery.

Since completing ramp-up of the sulfide plant in June 2020, POX throughput has progressively improved to exceed design up to a monthly average peak of 350 tonnes per hour and at the maximum sulfide sulfur of 14.25 tonnes per hour. Gold recovery has remained at around 90.0% with the tailings grade ranging between about 0.25–0.30 grams of gold per tonne.

During the proposed oxide ore campaigns, a pipeline that was installed for plant commissioning will be used to bypass the oxide ore around the autoclaves directly to the leaching and recovery circuits.

SLR International Corporation and RSC Consulting Ltd., as Qualified Persons defined under S-K 1300 and NI 43-101, are of the opinion that there are no material changes to the Mineral Resources and Reserves described herein as compared to the information presented in the Çöpler TRS.

Core (“Diamond Drilling-DD”) and Reverse Circulation (“RC”) drilling on the property is the principal method of exploration and delineation of gold mineralization after initial targeting using soil sampling and geophysical surveys. Since 2000, the Company’s exploration program within the Çöpler district has identified several new gold-dominant and copper–gold prospects. The gold-dominant regional prospects include the Çöpler Saddle and Elmadere. Copper–gold prospects include Aslantepe, Sarıdere, Fındıklıdere, and Mavidere porphyries located within the Mavialtın Porphyry Belt and the early exploration stage Meşeburnu porphyry located west of the Çöpler deposit.

Drilling at the Çöpler deposit commenced in 2000 and since that time a total of 3,177 holes have been drilled for 436,957 meters. During the year ended December 31, 2025, a total of 33 geotechnical and hydrogeological holes were drilled for 2,147 meters.

Drilling at Çakmaktepe commenced in 2012. A total of 136 diamond core holes have been completed since 2019 to test for continuation of the Çakmaktepe deposit to the north and the east. There has been no activity in 2025.

Since the initial discovery of mineralization at Çakmaktepe Extension, Anagold has undertaken several drilling programs to refine the geological model and increase mineral resources. A total of 767 diamond core holes for 162,890 meters at Çakmaktepe Extension from late-2017 through December 2023, including holes for metallurgical testing and hydrogeological studies.

Data verification was completed as part of the generation of the mineral resources estimate. All data collected, including but not limited to collar location, downhole survey, geological, and analytical data, are subject to SSR Mining's QAQC procedures.

Oxide Grind Leach

The Company is reviewing a proposed process to treat oxide ores from the Çakmaktepe Extension open pit. Based on the information and metallurgical test results, low-sulfur mineralization is amenable to cyanide leaching as a recovery method; grinding the ore prior to cyanide leaching increases both the reaction kinetics and final recoverable metal. The throughput of the proposed plant is four million tonnes per annum (“Mtpa”). The process is an industry-standard crushing, grinding, leaching, and carbon adsorption plant with recovery of gold and silver from the leach solution by carbon adsorption, desorption, electrowinning, and refining to produce a gold doré. The Oxide Grind Leach plant requires 500 m 3/h of make-up water from a combination of raw and process water sources.

Remediation Activities

Remediation efforts to remove the displaced heap leach material began shortly after the Çöpler Incident following extensive consultation and evaluations with and by various Turkish government agencies, ministries, independent experts, and external consultants. All displaced heap leach material in the Sabırlı Valley had been removed and transferred to temporary storage on the mine site by the end of 2024. The design of the repository TSF2 to facilitate long term storage of heap leach material displaced was advanced during 2025. The design work for the repository will continue into 2026. The design of the Heap Leach Facility remediation plan was advanced in 2025 and will continue into 2026. The work includes an extensive field program to collect critical engineering data. Extensive consultation and evaluations with and by various Turkish government agencies, ministries, independent experts, and external consultants will continue in 2026.

Marigold Complex, Nevada, United States

The Marigold Complex includes the Marigold Mine (including Mackay, Valmy, and New Millennium), Buffalo Valley, and other minor deposits. Marigold Mine is an open pit mining and processing operation located in Nevada, United States. SSR Mining, through its subsidiary Marigold Mining Company, is the operator of the Marigold Complex and holds a 100% interest in the property.

The total cost of the Marigold Complex’s gross mineral properties, plant, and equipment as of December 31, 2025 was $697.4 million.

Marigold is located in southeastern Humboldt County, in the northern foothills of the Battle Mountain Range, Nevada, United States, approximately 5 kilometers south–southwest of the town of Valmy, Nevada. Access to the property is via a five kilometer public road (hard-packed clay and gravel) off the Valmy Exit 216 on Interstate Highway 80. Other nearby municipalities include Winnemucca and Battle Mountain, Nevada, which lie approximately 58 kilometers to the northwest and 24 kilometers to the southeast of the property, respectively. Activities at the property are centered at approximately 40°45′ North latitude and 117°8′ West longitude.

The Marigold Complex includes two main land packages, the Marigold Land Package and the Sterling Land Package (collectively, the “Marigold Property” or “Marigold project areas”). The Marigold Land Package encompasses approximately 10,477 hectares, including the approximately 3,296 hectares within the Marigold Mine Plan of Operations (“PoO”). The Sterling Land Package (9,383 hectares) includes properties associated with the Buffalo Valley Mine.

History

Marigold has been in continuous operation for more than 30 years. The first recorded gold production from the Marigold Property occurred in 1938 when the Marigold Mining Company operated an underground mine which came to be known as Marigold. The Marigold Property was explored and developed by various companies and operations from 1968, with two million ounces of gold recovered from Marigold by mid-2009. The Company acquired Marigold in April 2014 from subsidiaries of Goldcorp and Barrick. In August 2015, Marigold mine acquired 2,844 ha of adjacent land from Newmont Corporation (“Newmont”). In June 2019, SSR Mining acquired the Buffalo Valley property from Newmont, which is located in an 8,900 ha parcel contiguous to the south boundary of the Marigold Property.

Marigold is located in the Battle Mountain mining district of north-central Nevada within the Basin and Range physiographic province bounded by Sierra Nevada to the west and the Colorado Plateau to the east. The Battle Mountain district hosts numerous mineral occurrences, including porphyry copper–gold, porphyry copper–molybdenum, skarn, placer gold, distal disseminated silver-gold, and Carlin-type gold systems. The gold deposits at the Marigold Mine are best classified as Carlin-type gold deposits (“CTGD”). Gold mineralizing fluids were primarily controlled by fault structure and lithology, with tertiary influence by fold geometry. Gold occurs natively as submicron scale particles in fractures in association with iron oxide. Rocks within the Marigold mine area are oxidized to a maximum depth of approximately 450 meters. The Buffalo Valley gold deposit is a distal disseminated silver-gold deposit and formed along a southeast trending zone of felsic porphyry dikes and faults.

Marigold uses standard open pit mining methods. Mining operations are currently performed using a loading fleet consisting of one electric shovel and three hydraulic shovels and a haulage fleet of twenty-seven 280 tonne trucks. The mine conducts conventional drilling and blasting activities with a free face trim row blast to ensure stable wall rock conditions. Drilling and blasting occur on benches with a height of 15.2 meters. A geotechnical management plan includes highwall monitoring using radar systems. Equipment maintenance is performed on site for all equipment.

The infrastructure facilities at Marigold include ancillary buildings, offices and support buildings, access roads into the plant site, power distribution, source of fresh water and water distribution, fuel supply, storage and distribution, waste management, and communications. The nearby towns of Winnemucca and Battle Mountain, NV host a majority of the skilled labor workforce. The current Marigold workforce totals 493 employees.

The power supply for Marigold is provided by NV Energy Inc. Water for Marigold is supplied from three groundwater wells located near the access road to the Property. Marigold owns sufficient ground water rights to support mine operations. Water is primarily consumed by retention in the heap leach pad, evaporation, processing operations, and dust suppression.

Marigold holds valid permits for all facets of the current mining operation as required by county, state, and federal regulations. The Company engages in concurrent reclamation practices and is bonded for all permitted features, as part of the Nevada permitting process.

Surface and mineral rights at Marigold comprise the following: real property and unpatented mining claims, in each case owned by Marigold, and leasehold rights held by Marigold with respect to unpatented mining claims, mill site claims, and certain surface lands. The Company performs duties on leased lands pursuant to all federal and state requirements to maintain leases in good standing. Some of the leases require Marigold to make certain NSR royalty payments to the lessors and comply with other obligations, including completing certain work commitments or paying taxes levied on the underlying properties.

All Marigold ore deposits are processed via truck dump run-of-mine (“ROM”) heap leaching. Gold recovery from future ore is estimated to be 74.5% based on a review of historical assay and recovery data as well as metallurgical test work on future ore.

Metallurgical studies were performed by Newmont on the Buffalo Valley deposit and subsequently verified by test work conducted by SSR Mining. Based on the results, ROM recoveries at Buffalo Valley vary between 10.9% to 81.9% and crush recoveries vary between 13.7% to 84.2% based on lithologies.

Marigold processing plant and processing facilities combine ROM cyanide heap leaching and recovery of gold from the leach solution using carbon adsorption, desorption, electrowinning, and refining to produce gold doré. All processing of ore, which is oxide in nature, is completed via ROM heap leaching. ROM ore is delivered to the leach pad by mine haul trucks and stacked in 6 meter to 12 meter lifts.

Cumulative gold production from the Marigold leach pad through December 31, 2025 is equivalent to 71.6% recovery, and total gold recovery, including recoverable gold inventory in the pad, is estimated at 73.9%.

The following tables present the mineral reserves and mineral resources information for Marigold.

Factors contributing to the changes include: (i) reduction of Buffalo Valley Mineral Resources due to conversion, (ii) re-interpretation of the mineralized envelopes using the most updated drill hole information, (iii) change to optimization parameters with regards to metal price and cost changes, and (iv) depletion.

SLR International Corporation, as Qualified Person defined under S-K 1300 and NI 43-101, is of the opinion that there are no material changes to the Mineral Resources and Mineral Reserves described herein as compared to the information presented in the Marigold TRS.

Since acquiring the Marigold Property, the Company has conducted several surface exploration programs including soil sampling, geophysics, and in-fill/delineation drilling. Reverse Circulation (“RC”) and Core (“Diamond Drilling-DD”) drilling on the Marigold Property is the principal method of exploration and delineation of gold mineralization. As of December 31, 2025, over 2.54 million meters of drilling in 13,342 drill holes across the Marigold, Buffalo Valley, and other areas have been completed.

During the year ended December 31, 2025, the Company has completed 52,001 meters in 243 drillholes at Marigold, Trenton Canyon and Buffalo Valley. The objective of the drilling was to increase the confidence in resource estimates, resource expansion, and drillholes for geotechnical metallurgical and hydrogeological purposes.

Since 2014, all exploration samples from Marigold are analyzed at American Assay Laboratories (“AAL”), an ISO 17025 certified facility in Sparks, Nevada or were assayed at Paragon Laboratories (2019-2020). Both AAL and Paragon laboratories are independent from the Company. ALS, Reno is used as umpire check sample analysis. The drill and geochemical samples are collected in accordance with accepted industry standards.

Data verification was completed as part of the generation of the mineral resources estimate. All data collected, including but not limited to collar location, downhole survey, geological, and analytical data, are subject to SSR Mining's QAQC procedures.

Cripple Creek and Victor Gold Mine, Colorado, United States

Cripple Creek and Victor Gold Mine is an open pit mining and processing operation located in Colorado, United States. SSR Mining, through its subsidiary CC&V, is the operator and holds a 100% interest in the property.

The total cost of the CC&V’s gross mineral properties, plant, and equipment as of December 31, 2025 was $366.6 million.

CC&V is located in Teller County, Colorado, United States, within the historical Cripple Creek Mining District. The site lies approximately 160 kilometers southwest of Denver, and is situated between the towns of Cripple Creek and Victor. Access to the mine site is within a mile of public roads in the vicinity of Cripple Creek and Victor. The usual access to the area is west from Colorado Springs on State Highway 24 (about 25 miles) to the community of Divide, then south from Divide on State Road 67 (approximately 20 miles). Activities at the property are centered at approximately 38°45′04.79” North latitude and 105°09′ 05.41” West longitude at an elevation of approximately 3,114 meters above sea level.

CC&V maintains ownership or control over a significant land package critical to mining operations. CC&V’s land tenure is comprised of approximately 1,642 patented mining claims, two state mining leases, four private mining leases, 25 mineral parcels, 134 surface parcels, and 13 unpatented lode claims encompassing a total area of approximately 15,012 acres. Mine operations are situated within a permit boundary referred to as the Amendment 13 Permit Boundary or the “A13 Permit Boundary.”

History

Gold was discovered in the district in the early 1890s, leading to a rapid boom. Underground mining operations dominated through the early 20th century, producing over 23 million ounces (“Moz”) of gold. By 1962, most underground mining had ceased. To date, approximately 30 Moz of gold have been produced from the CC&V area. Modern surface mining began in 1994 under the Cripple Creek & Victor Gold Mining Company, with several ownership changes leading to SSR Mining’s acquisition of CC&V in 2025 from Newmont Mining Corporation.

CC&V is an epithermal, alkaline intrusion-related gold system hosted in an Oligocene-aged diatreme composed of volcanic and volcaniclastic rocks, primarily quartz latite. Gold mineralization occurs as native gold and gold-silver tellurides within breccias, stockworks, and hydrothermal veins, typically associated with pyrite, quartz, and fluorite. Rocks within the CC&V mine area are oxidized to a maximum depth of approximately 450 meters.

CC&V uses standard open pit mining methods. Mining operations are currently performed using a loading fleet consisting of two front-end loaders and two hydraulic shovels and a haulage fleet of twenty-one 220 tonne trucks. The mine conducts conventional drilling and blasting activities with a free face trim row blast to ensure stable wall rock conditions. Drilling and blasting occur on benches with a height of 10.7 meters. A geotechnical management plan includes highwall monitoring using radar systems. Equipment maintenance is performed on site for all equipment.

The infrastructure facilities at CC&V include ancillary buildings, offices and support buildings, access roads, power distribution, source of fresh water and water distribution, fuel supply, storage and distribution, waste management, and communications. The region provides access to a skilled mining and industrial labor pool, particularly from the city of Colorado Springs (approximately 80 kilometers east), the towns of Cripple Creek, Victor, and Florissant. The current CC&V workforce totals 427 employees.

The power supply for CC&V is provided Black Hills Energy through regional transmission lines. All water used on site is purchased from local municipalities and utility companies. The availability, reliability, and security are ensured through multiple water agreements and contracts with the City of Victor, the City of Cripple Creek, Colorado Springs Utility (“CSU”), Pueblo Board of Water Works and Catlin Canal Company. Water is primarily consumed by retention in the heap leach pad, evaporation, processing operations, and dust suppression.

CC&V holds valid permits for all facets of the current mining operation as required by county, state, and federal regulations.

CC&V has several agreements existing with federal, state, and third-party entities which are monitored using a land management database. The data managed includes contractual obligations, leases, associated payments, parties to agreements, and locations and details of the properties that the agreements cover. All mining leases are managed and reviewed monthly, and all payments and commitments are paid as required by the specific agreements. CC&V is subject to a variety of NSR royalty payments, payable to various parties under the terms of the agreements. The average NSR royalty payments range from 0.5% to 10.0%. As per SSR Mining’s finance team analysis, a weighted average rate of 5% was used for cash flow modeling purposes.

Metallurgical testing at CC&V is performed to support the operating VLF and milling facilities and to determine the metallurgical characteristics of new ore deposits included in the mine plans.

Results from ongoing test programs, combined with relevant historical data, are interpreted to inform and update key process models used to support operations. Specifically, leach recovery models will be revised to incorporate the latest column and bottle roll test results.

CC&V utilizes two valley-leach facilities (“VLF 1” and “VLF 2”) for gold recovery. Each leach facility is integrated with its own dedicated adsorption-desorption-recovery (“ADR”) plant.

Ore processing includes a crushing facility, which consists of a primary 60 x 89 Svedala Type NT gyratory crusher, followed by a Nordberg MP1000 secondary cone crusher. The plant is designed to crush 50,000 tpd with an operating availability of 75%, producing a final crushed product with a P 100 at 20 mm.

VLF 1 predominantly contains crushed ore, with a cumulative total of approximately 335 million tonnes placed since operations began in 1994. Ore stacking on VLF 1 concluded in 2015; however, the leaching process remains ongoing through continued injection of barren solution. This is primarily accomplished via jet injection methods, with current solution flow rates ranging between 1,600 and 2,250 cubic meters per hour (“m 3/hr”). As of the end of 2025, approximately 275 injection wells have been installed across the pad to facilitate efficient solution distribution and sustained recovery.

Active ore placement on VLF 2 commenced in late 2015. By the end of March 2025, approximately 192 million tonnes of ore had been stacked. Most of the material placed on VLF 2 is run-of-mine (“ROM”) or lower grade, with only a small portion, approximately 5%, being primary crushed prior to stacking.

Mineral Resources exclusive of Mineral Reserves at CC&V as of December 31, 2025 has decreased compared to July 1, 2025, the date of the CC&V TRS. Measured and Indicated contained gold ounces decreased by 39 koz, or 1%, and Inferred gold ounces decreased by 3 koz, or 0.1%, due to depletion.

SLR International Corporation, as Qualified Person as defined under S-K 1300, is of the opinion that there are no material changes to the Mineral Resources and Mineral Reserves described herein as compared to the information presented in the CC&V TRS.

Since acquiring CC&V, the Company initiated both Mineral Resource expansion and grade control drilling program within the Stockpile (Dump1) area. RC and Diamond Drilling drilling on the property is the principal method of exploration and delineation of gold mineralization with limited Sonic drilling being carried out in unconsolidated rock mass (dumps). As of December 31, 2025, over 2.85 million meters of drilling in 17,761 drill holes have been completed.

During the year ended December 31, 2025, the Company completed 13,352 meters in 134 drillholes at CC&V. The objective of drilling was to increase the confidence in resource estimates, resource expansion, and confirmation of grades in the Stockpile.

Since 2025, all exploration samples from CC&V are analyzed at ALS Chemex (“ALS”), an ISO 17025 certified facility. ALS laboratories are independent from the Company. American Assay Laboratories, Reno, Nevada and SGS is used as umpire check sample analysis. The drill and geochemical samples are collected in accordance with accepted industry standards.

Data verification was completed as part of the generation of the mineral resources estimate. All data collected including but not limited to collar location, downhole survey, geological and analytical data are subject to SSR Mining's QAQC procedures.

Seabee Gold Operation, Saskatchewan, Canada

The Seabee Gold Operation is an underground gold mining and milling operation, located in Saskatchewan, Canada. SSR Mining holds a 100% interest in the property through its wholly‑owned subsidiary, SGO Mining Inc., which also acts as operator for Seabee.

The total cost of Seabee’s gross mineral properties, plant and equipment as of December 31, 2025 was $650.4 million.

Seabee is located at the north end of Laonil Lake, approximately 125 kilometers north-east of the town of La Ronge, Saskatchewan, Canada. Activities at the property are centered at approximately 55°41’ North latitude and 103°37’ West longitude.

Ore is currently produced from the Santoy underground mine from a ramp access/surface portal and is hauled 14 kilometers to the mill located at the Seabee site. A second underground mine, also having ramp access, was operated from 1991–2018 at Seabee. All ore is processed at the Seabee mill facility, which is located adjacent to the now-closed Seabee mine and has been in operation since 1991. The Seabee mill facility produces gold doré bars that are shipped to a third-party refinery.

The mine is a remote operation. Seabee is accessible by fixed-wing aircraft from the towns of LaRonge, Prince Albert, and Saskatoon, Saskatchewan and during the winter months, typically January through the end of March, a 60 kilometer winter road is also built between the mine site and Brabant Lake, approximately 120 kilometers north of La Ronge.

Seabee is comprised of seven mineral leases and 130 mineral claims that cover an area of approximately 73,820 hectares, including the Fisher Property rights. Seabee is subject to production and NSR royalties payable to third parties, including certain royalty payments to the Province of Saskatchewan, which are calculated on 10% of net operating profits and are payable once capital and exploration costs are recovered. The other NSR royalty payments are based on specific gold production and/or sales and vary between 1.0% and 3.0% of the value of gold production and/or sales, as applicable.

Seabee currently has a valid surface lease with the Province of Saskatchewan, which was amended in March 2010. This surface lease provides land surface rights necessary to carry out the mining, milling and associated operations at the Seabee. The existing surface lease is in effect from March 2010 to its expiry date of May 31, 2040.

The operations at Seabee were temporarily suspended in June 2025 due to forest fires in the vicinity of the mine. The Seabee processing plant and Santoy mine were not materially impacted by the fires. Operations were fully reinstated in late June 2025.

History

The Laonil Lake region has been intermittently explored since the 1940’s, with the first gold discovery made by prospectors in 1947, with detailed drilling and exploration of the property constituting the Seabee conducted from 1947 until construction of the Seabee mill was initiated in the summer of 1990. Mill construction was completed in late 1991 and mining commenced in December 1991. Exploration and production expanded into the Santoy segment of the property through the early 2000s.

The Company acquired Seabee on May 31, 2016. Seabee has produced over 1.90 million ounces of gold since production began in 1991.

Northern Saskatchewan forms part of the Churchill Province of the Canadian Shield and has been subdivided into a series of litho-structural crustal units. Seabee is located within the Glennie domain of the Proterozoic Trans-Hudson Orogen. All the main gold deposits at Seabee are considered orogenic quartz-vein hosted lode gold deposits. Gold mineralization at the Santoy mine complex is hosted within the Santoy Shear Zone (“SSZ”); a kilometer scale shear zone with a roughly north-south strike that dips moderately to steeply to the east. Gold mineralization at the Porky deposits (Porky Main and Porky West) occurs along the western margin of the Ray Lake synform within a kilometer scale shear zone, the Pine Lake Shear Zone (“PLSZ”), that strikes east-southeast and dips moderately to the south.

There is currently one operating mine as part of Seabee, the underground Santoy mine, with ore hauled to the surface and then 14 kilometers to the mill located near the old Seabee mine. At Santoy mine, ore is mined from the Santoy 8, Santoy 9, and Hanging Wall vein structures.

Access underground at the Santoy mine is provided from the surface via a main ramp with sublevels spaced between 17–20 meters vertically. Mining is carried out using sublevel open stoping mining methods with backfill, with stopes filled with a combination of rock fill and cemented rock fill, mined in a bottom-up mining sequence. Sill pillars are mined on retreat once the stopes below and above have been mined.

Infrastructure, Permitting and Compliance Activities

The major infrastructure at the Seabee site includes roads, an airstrip, powerhouse and electrical distribution system, mill buildings, and related services facilities, Santoy mine portal and ventilation raises, equipment maintenance facilities, fuel storage, explosive storage, water supply and distribution, water management ponds and water treatment plant, tailings management facilities, administrative buildings and camp accommodation. Electrical power is provided by a transmission line to the site by the provincial power authority, Saskatchewan Power Corporation, connected to a 138 kV hydroelectric power line from Island Falls. The Santoy Mine has one water management structure, which is the Santoy 8 deposit water management pond. Potable water is obtainable locally through SSR Mining’s potable water system at both the Seabee and Santoy mine sites. The site currently uses a slow sand filter system. The current Seabee workforce totals 413 employees.

There are currently two tailings management facilities (“TMF”) that are being used by the mill; the East Lake TMF and the Triangle Lake TMF. Tailings deposition alternates between the two TMFs where winter deposition occurs in the Triangle Lake TMF and summer deposition is in the East Lake TMF. The remaining storage capacities of both facilities, based on the planned production rates, will potentially reach maximum capacity towards the end of 2030. To ensure that water treatment volumes are attained, a water treatment plant was constructed at East Lake TMF.

Seabee was originally developed based on bench-scale metallurgical testwork that characterized the Seabee deposit as a lode gold style of mineralization that was free milling and that would respond to a standard flow sheet employing gravity recovery and cyanidation.

Historical recovery at the Seabee mill was in the 94%–96% range, with routine low levels of losses both in the tailings solids and solution. Future recovery estimates are 96.4%, based on the recent mill performance with recoveries of more than 98%. These improvements are attributed to the better condition of the leach equipment as well as the restored leach capacity.

Testwork conducted in 2023 on the Porky West deposit show a metallurgical recovery of 96%, with a high proportion of recovery coming from gravity processing.

Material has been processed for 30 years in the mill constructed immediately adjacent to the old Seabee mine. The operation was initially developed and operated on diesel power and later connected to the Saskatchewan grid power in 1992. The initial capacity of the mill was 500 tonnes per day, which was later expanded to a nameplate capacity of 1,000 tonnes per day, with the addition of a third grinding mill in 2005. The mill flow sheet is a conventional crushing and grinding circuit employing gravity concentration and cyanide leaching and carbon-in-pulp for recovery and production of gold doré on site.

Capital projects have included the addition of the primary ball mill and the addition of two further Knelson concentrators and Acacia intensive leach gold recovery unit. The current Seabee process plant capacity is nominally 1,425 tonnes per day, or 1,350 tonnes per day annual average. The Seabee operation is characterized by coarse gold, making the gravity recovery circuit critical to the overall gold recovery of the process plant. In recent years, with incorporation of gravity circuit improvements including the Acacia circuit, gold recovery has improved and is typically 98%.

Measured and Indicated contained gold ounces decreased by 199 koz, or 48%, and Inferred gold ounces decreased by 3 koz, or 1%. Factors contributing to the changes include: (i) conversion of Measured and Indicated Resources to Mineral Reserves at Porky West, (ii) re-interpretation of the mineralized envelopes using the most updated drill hole information, (iii) change to optimization parameters with regards to cost and cut-off grade, and (iv) depletion.

SLR International Corporation, as Qualified Person as defined under S-K 1300 and NI 43-101, is of the opinion that there are no material changes to the Mineral Resources and Mineral Reserves described herein as compared to the information presented in the Seabee TRS.

Since acquiring the property, the Company has conducted several surface and underground exploration programs including soil sampling, geophysics, and in-fill/delineation drilling. Core (“Diamond Drilling-DD”) drilling on the property is the principal method of exploration and delineation of gold mineralization.

During the year ended December 31, 2025, the Company completed a total of 9 drillholes totaling 1,788 meters from surface and 388 drillholes totaling 47,513 meters from underground drilling at the Santoy mine complex.

During the year ended December 31, 2025, the company completed a total of 151 drillholes totaling 34,727 meters of drilling at Porky West deposit. The main objective of this drilling was to infill the existing resource and to expand the footprint of mineralization and also for metallurgical test work. Mineral Resource at Porky West is open at depth and along strike. An exploration plan is in place to increase the Mineral Resource footprint and continue infill drilling in 2026.

To date, drilling completed on the Seabee property (by SSR Mining and previous operators) includes 2,824 surface drillholes totaling 658,596 meters and 7,367 underground drillholes totaling 1,345,357 meters.

Sampling interval was established by minimum or maximum sampling lengths and geological and/or structural criteria. During the year ended December 31, 2025, all drill samples in respect of the Seabee Gold Operation underground drilling program were assayed by our on-site non-accredited assay laboratory, which is not independent from the Company. All surface drilling samples and underground umpire samples in 2024 and 2025 were analyzed at ALS Vancouver laboratories, who is independent of SSR Mining.

Data verification was completed as part of the generation of the mineral resources estimate and all data collected, including but not limited to collar location, downhole survey, geological, and analytical data, are subject to SSR Mining's QAQC procedures.

Puna, Jujuy Province, Argentina

Puna comprises the Chinchillas property and the Pirquitas property, both of which are located the Jujuy Province in far north Argentina. SSR Mining holds 100% interest in Puna through its subsidiary, Puna Operations Inc., which also operates the project.

The total cost of Puna’s gross mineral properties, plant, and equipment as of December 31, 2025 was $431.6 million.

The Chinchillas property is located in the Puna region of northwestern Argentina, in the province of Jujuy, department of Rinconada, approximately 290 kilometers northwest of San Salvador de Jujuy. The property is most conveniently accessible from the provincial capital of San Salvador de Jujuy via National Route No. 9, leading northward along the Humahuaca River to the town of Abra Pampa, then via Provincial Route No. 7 for 66 kilometers and Provincial Route No. 70, passing through the village of Santo Domingo. Elevation of the property ranges from 4,000–4,200 meters above sea level. The property is centered at approximately 22°30’ South latitude and 66°16’ West longitude.

The Pirquitas property is also located in the Rinconada Department in the Province of Jujuy, approximately 45 kilometers southwest of the Chinchillas Property and approximately 335 kilometers northwest of San Salvador de Jujuy. Elevation of the property ranges from 4,000–4,450 meters above sea level. Activities at the property are centered at approximately 22°42’ South latitude and 66°29’ West longitude.

The Chinchillas property is composed of three contiguous claims, totaling 2,043 hectares. The Pirquitas property comprises 54 exploitation concessions that cover an area of approximately 9,742 hectares. All the exploitation concessions are valid and in good standing.

Ore from the Chinchillas mine is transported approximately 45 kilometers to the Pirquitas plant for processing. Concentrates produced at Puna are subject to a maximum 3% ‘mouth of mine value’ royalty that is payable to the Province of Jujuy. This royalty payment is based on the net recoverable value of the contained metals less certain operating costs.

History

Chinchillas was first prospected and mined in small scale in the eighteenth century by Jesuit missionaries. An initial mining concession was granted in 1956, with small scale production beginning in 1968 and continuing through 1982. Sporadic exploration and sampling programs were conducted at Chinchillas between 1982 and the mid-2010’s. Between the 1930’s and 1995 multiple small mining operations recovered silver and tin from placer and vein deposits in the vicinity of the Pirquitas mine. Comprehensive mineral exploration was conducted on the property between 1995 and 2000. The Pirquitas mine was formally inaugurated in April 2009, with commercial production starting in December of that year. Mining was completed in mid-January 2017. The Pirquitas processing plant has been in continuous operation since 2009.

The Chinchillas and Pirquitas deposits are considered part of the Bolivian tin-silver–zinc belt that extends from the San Rafael tin-copper deposit in southern Peru into Bolivia and then the Puna region of Jujuy. Deposits with similar styles of mineralization include San Cristóbal, Potosí, and Pulacayo. These deposits are characterized by dacite dome complexes with mineralization hosted in shears and breccias within the dacite domes or within shears and breccias within the host rocks. More rarely, as in the case of the Chinchillas Property and San Cristóbal, the deposits morphology includes flat-lying manto bodies within sedimentary and pyroclastic rocks. All the deposits have large vertical extents.

Significant silver-lead-zinc mineralization occurs in five principal areas at the Chinchillas: the Silver Mantos and Mantos Basement zones in the west part of the Project, the Socavon del Diablo and Socavon Basement zones in the east and Melina to the northeast.

The Pirquitas deposits includes Potosi, San Miguel, Chocoya, Oploca, San Pedro, Llalagua, Chicharron, Colquiri veins and Cortaderas breccia. The San Miguel pit contained portions of the Potosi, San Miguel and Chocoya vein systems. Veins within the San Miguel pit have a strike of west-northwest and are generally sub-vertical.

The Cortaderas mineralization is located north of the San Miguel pit. Mineralization at Cortaderas is Zinc rich and is hosted mainly within multiple vein like breccia bodies. The mineralization thickness of each breccia body varies between 0.5 meters and 7.0 meters with an overall strike length of 500 meters. Two different zones of mineralization have been identified i) Main Cortaderas breccia trending northwest-southeast and dipping steeply to the southwest, and ii) parallel Hanging-wall breccia dipping steeply to the northeast. The 2025 drilling has identified the Submarino mineralization, a northwest extension of the Cortaderas main breccia.

The Chinchillas deposit is mined as a conventional open pit operation. In-pit haulage for both ore and waste utilizes 100 tonne haul trucks. Ore is mined in five-meter benches and stockpiled in a staging area close to the pit. In the staging area, ore is loaded onto 35 tonne road trucks and transported to the processing facility at Pirquitas. Low-grade ore is stockpiled near the pit rim for processing at the end of mine life. Waste rock is hauled to on-site waste rock storage facilities.

Electricity at Chinchillas is supplied through power lines from natural gas generators at Pirquitas. Water for mining operations is drawn from wells, while bottled potable water is imported to site. Non-potable water is pumped from a diversion upstream of the open pit for use at the camp. Infrastructure at Chinchillas consists of technical offices, maintenance facilities, and limited camp and medical facilities. The current Puna workforce totals 853 employees.

Pirquitas is a permitted commercial mine and processing facility, operated by SSR Mining since December 2009, with infrastructure that includes a processing plant, a tailings facility, a fully serviced workers camp sufficient for approximately 670 personnel, a communications system including cellular and intranet access, office buildings, wastewater treatment facilities, organic waste landfill, and recycling center. Electricity is produced from natural gas generators at Pirquitas.

Government permits required to conduct exploration, drilling, and processing at Puna have been obtained.

The metallurgical development of Chinchillas ore types commenced in 2013 and continued through 2023. There have been six different test work programs that have been carried out on the Chinchillas ore. The latest test campaign wrapped up in 2023, which further tested the Socavon and Melina targets; this test work split the flow sheets based on the Zn to Pb ratio. The Pirquitas process plant operating performance since commencement on Chinchillas ores is used to provide the concentrate grade recovery and mass pull relationships. The recovery is variable based on the head grade and the average is 96.2% for silver, 93.0% for lead and 40.8% for zinc.

The Pirquitas processing plant consists of crushing, grinding, and froth flotation to produce two products, silver-lead and zinc concentrates. These two product concentrates are bagged separately in one tonne bags and transported to a port by truck for export to smelters. The Pirquitas process plant has continued to improve performance from the expected 4,000 tonnes per day feed capacity to 5,000 tonnes per day achieved in 2023 and sustained through 2024 and 2025.

SLR International Corporation, as Qualified Person, as defined under S-K 1300 and NI 43-101, is of the opinion that there are no material changes to the Mineral Resources and Mineral Reserves described herein as compared to the information presented in the Puna TRS.

At Chinchillas, previous exploration programs included geological mapping, geophysical surveying, and diamond drilling to identify and delineate mineralized areas. At Pirquitas, exploration programs included geological mapping, geophysical surveying, underground rock sampling, and multiple programs of RC and diamond drilling.

In 2025, exploration drilling was conducted at Pirquitas. During the year ended December 31, 2025, a total of 40 drillholes totaling 19,922 meters was completed at Pirquitas. Drilling focused on infill and extensional drilling on the Cortaderas deposit. Resource extension drilling identified new vein systems to the northwest of the main Cortaderas vein as well as additional veins in the footwall.

Historically the samples have been assayed at ALS-Peru, Alex Stewart, Argentina SA, SGS Chile and AAL laboratories. In 2022 samples were sent to the ALS Mendoza laboratory, where the physical preparation of the samples was performed. The majority of the analyses were carried out in the ALS laboratory in Lima, Peru with the samples being transported by intercompany transfer.

The 2025 samples were analyzed by Alex Stewart International, with the physical preparation carried out in Palpala, Jujuy, and the chemical analysis performed in Mendoza. Sample shipment between Jujuy and Mendoza was managed by Alex Stewart following arrival in Jujuy.

Both Alex Stewart and ALS are international laboratories certified under ISO 9001:2008, ISO 17025:2008, and ISO 14001: 2004. Alex Stewart and ALS are independent from SSR Mining. Data verification was completed as part of the generation of the mineral resources estimate. All data collected, including but not limited to collar location, downhole survey, geological, and analytical data, are subject to SSR Mining's QAQC procedures.

Internal Controls over the Mineral Reserves and Mineral Resources Estimation Process

The Company has internal controls over the mineral reserves and mineral resources estimation processes that result in reasonable and reliable estimates aligned with industry practice and reporting regulations. Annually, the Qualified Persons and other employees review the estimates of mineral reserves and mineral resources, the supporting documentation, and compliance to the internal controls, and, based on their review of such information, recommend approval to use the mineral reserve and mineral resource estimates to our senior management. The Company’s controls utilize management systems including but not limited to, formal quality assurance and quality control protocols, standardized procedures, workflow processes, supervision and management approval, internal and external reviews and audits, reconciliations, and data security covering record keeping, chain of custody and data storage.

The Company’s systems also cover exploration activities, sample preparation and analysis, data verification, mineral processing, metallurgical testing, recovery estimation, mine design and sequencing, and mineral reserve and resource evaluations, with environmental, social and regulatory considerations. The Company’s quality assurance and control protocols over sampling and assaying of drill hole samples include insertion of blind samples consisting of standards, blanks, and duplicates in the primary sample streams, as well as selective sample validation at secondary laboratories.

These controls and other methods help to validate the reasonableness of the estimates. The effectiveness of the controls are reviewed periodically to address changes in conditions and the degree of compliance with policies and procedures. Refer to Item 1A. Risk Factors for discussion of risks associated with our estimates of mineral reserves and mineral resources.

Proven and Probable Reserve Estimates by Mineral

The following information about Çöpler is historical in nature and is as of February 13, 2024 only. As described in“Item 1. Business - Çöpler Incident”, all operations at Çöpler have ceased following the Çöpler Incident and we are unable to determine at this time when operations at Çöpler will resume, if at all. We have not determined that, if we resume operations at Çöpler, the proven and probable reserve estimates by mineral for Çöpler presented below continues to be accurate or will be accurate at such time as the Company resumes operations at Çöpler.

Proven and probable Mineral Reserves are based on extensive drilling, sampling, geological modeling, and metallurgical testing from which economic feasibility has been determined. The price sensitivity of Mineral Reserves depends upon several factors including grade, metallurgical recovery, operating cost, waste-to-ore ratio and ore type. Metallurgical recovery rates vary depending on the metallurgical properties of each deposit and the production process used. The Mineral Reserve tables below list the average metallurgical recovery rate for each deposit, which takes into account the several different processing methods to be used. The cut-off grade, or lowest grade of mineralized material considered economic to process, varies with material type, metallurgical recoveries and operating costs.

The proven and probable Mineral Reserves presented herein are estimates based on information available at the time of calculation. No assurance can be given that the indicated levels of recovery of gold, silver, copper, lead, and zinc will be realized. Ounces of gold or silver, or pounds of copper, lead or zinc in the proven and probable Mineral Reserves are calculated without regard to any losses during metallurgical treatment. Mineral Reserves estimates may require revision based on actual production experience. Market price fluctuations of gold, silver, copper, lead, and zinc, as well as increased cost of sales or reduced metallurgical recovery rates, could render proven and probable Mineral Reserves containing relatively lower grades of mineralization uneconomic to exploit and might result in a decrease in actual recovery as compared to the Mineral Reserves reported herein.

The Mineral Reserves presented below as of December 31, 2025 and December 31, 2024 have been prepared in accordance with the U.S. Securities and Exchange Commission (“SEC”) Regulation S-K subpart 1300 rules for Property Disclosures for Mining Registrants (“S-K 1300”), and have been approved by the Qualified Persons. Mineral Reserves metal prices used for preparation of the 2025 Reserve estimate, which were selected, in each case, by the Qualified Persons are: $1,700 per gold ounce, $20.50 per silver ounce, $0.90 per lead pound, $1.15 per zinc pound, and $3.50 per copper pound unless otherwise stated. The Mineral Reserves metal price assumptions for 2024 report are: $1,500 per gold ounce, $19.00 per silver ounce, $0.90 per lead pound, $1.05 per zinc pound and $3.30 per copper pound unless otherwise stated.

The point of reference for Mineral Reserves is the point of feed into the processing facility for all production projects except for Marigold and CC&V, which is entry into the carbon columns in the processing facility.

Metals shown in the table are contained metals in ore mined and processed.

Tonnage is metric kilo tonnes (“kt”), ounces (“oz”) represent troy ounces, grade is grams per metric tonne (“g/t”), copper, lead and zinc grade are percent (“%”), and copper, lead and zinc metal are in million pounds (“Mlbs”).
