The Whistler Project
Other than under “2023 Exploration and Drilling Update” herein, the following information is condensed and extracted from the S-K 1300 Report. Readers should refer to the full text of the S-K 1300 Report, attached hereto as Exhibit 96.1, for further information regarding the Whistler Project.
Project Description, Location and Access
The Whistler Project is a gold-copper exploration project located in the Yentna Mining District of Alaska, approximately 170 km northwest of Anchorage.
As of the date hereof, the Whistler Project comprises 377 State of Alaska mining claims covering an aggregate area of approximately 217.5 km 2. The center of the property is located at 152.566° longitude west and 61.983° latitude north. The Whistler Project is located in the drainage of the Skwentna River. Elevation varies from about 400m above sea level in the valley floors to over 5,000m in the highest peaks.
A base camp and gravel airstrip for wheel-based aircraft is established adjacent to the Skwentna River. The camp is equipped with diesel generators, a satellite communication link, tent structures on wooden floors and several wood-frame buildings. Although chiefly used for summer field programs, the camp is winterized. The camp has been maintained in good condition, and tent-based structures damaged by heavy snow loads prior to 2023 were subsequently repaired or replaced during the 2023 summer field season.
Additionally, the Alaska State Government in 2021 invested US$8.5M in a Roads to Resources initiative which is being managed by the Alaska Industrial Development and Export Authority (“AIDEA”). AIDEA has published several studies since 2014 to assess route alternatives, impacts and benefits of constructing a public access road from Palmer/Wasilla to the ‘Susitna Mining District’ in the Alaska Range. In October 2021 AIDEA received US$8.5Mto advance pre-development work on the West Susitna Access Road (“WSAR”). In 2022 AIDEA applied for a CWA 404 permit application to the US Army Corp of Engineers for the West Susitna Access project, initiating the environmental review process through compliance with the National Environmental Policy Act. Field studies proceeded in 2022 and 2023 with further evaluation of cultural and historical sites, fish and wildlife habitat, engineering refinement and alternative route analysis. On July 27, 2023, the Alaska Department of Transportation and Public Facilities (“DOT&PF”)announced plans to include the first 15 miles of the WSAR, including a bridge over the Susitna River, within the draft ‘2024-2027 Statewide Transportation Improvement Program’, with funding set aside for construction to begin in 2025, pending permitting. Subsequent to the DOT&PF announcement, on July 28, 2023, AIDEA announced that it will continue working on a separate and additional portion of the WSAR, extending beyond the proposed DOT&PF road build to establish an industrial access corridor to several exploration and development projects in the West Susitna Mining District, including the Whistler Project. The development of this additional infrastructure may have a positive impact on reducing the future capital requirements and operating cost profile for the Whistler Project.
The following map sets forth the location of the Whistler Project and shows the proposed alignment of the West Susitna Access Road.
We acquired rights to the Whistler Project and associated equipment in August 2015 for a total cost of approximately $1.32 million pursuant to an asset purchase agreement by and among us, GoldMining, Kiska and Geoinformatics. Pursuant to such agreement, we acquired rights and assumed obligations under several related underlying agreements. The related underlying agreements on the Whistler Project are listed below:
| 1. | The first underlying agreement is a royalty purchase agreement between Kiska, Geoinformatics, and MF2, LLC, (“MF2”) dated December 16, 2014. This agreement granted MF2 a 2.75% NSR royalty over the Whistler Project area, and, extending outside the current claims, over an area of interest defined by certain maximum historical extent of claims held on the Whistler Project. |
| 2. | The second underlying agreement is an earlier agreement between Cominco American Incorporated (“Cominco”) and Kent Turner dated October 1, 1999. This agreement concerns a 2.0% net profit interest to Teck Resources Limited (“Teck Resources”), which net profit interest was purchased by Sandstorm Gold Ltd. in connection with an area of interest specified by standard township sub-division. |
| 3. | The third underlying agreement is a purchase and sale agreement among Kent Turner, Kiska and Geoinformatics, dated December 16, 2014, that terminated the “Turner Agreement” (which granted Kennecott Exploration Company (“Kennecott”) and its successors a 30-year lease on 25 unpatented State of Alaska Claims), and transferred to Kiska and Geoinformatics, and their successors, an undivided 100% of the legal and beneficial interest in, under, to, and respecting the Turner property free and clear of all encumbrances arising by, through or under Turner other than the Cominco American Incorporated net profit interest. |
In January 2023, we were granted 73 new claims, acquired by staking, in Alaska by the Division of Mining, Land and Water, ADNR. These additional claims are ancillary to the core project area which contains the Whistler, Raintree and Island Mountain Mineral Resources. These new claims provide flexibility for possible future exploration or operational needs. There is no known extension of Mineral Resources or unclassified mineralization or interpreted geological prospectivity underlying the new claims. Currently, we have no immediate plans for exploration on these claims, however they will be assessed in the future for possible work programs. We may also in the future evaluate and acquire additional interests in gold and gold-copper projects in the Americas.
We are also party to a royalty agreement with Gold Royalty Corp. dated January 11, 2021. This agreement granted to Gold Royalty Corp. a 1.0% NSR royalty on each of the Whistler, Raintree West and Island Mountain deposits/properties comprising the Whistler Project.
History
Mineral exploration in the Whistler area was initiated by Cominco in 1986 and continued through 1989. During this period, the Whistler and the Island Mountain gold-copper porphyry occurrences were discovered and partially tested by drilling. In 1990, Cominco ceased exploration and all cores from the Whistler region were donated to the State of Alaska and the property was allowed to lapse.
In 1999, Kent Turner staked 25 State of Alaska mining claims at Whistler and leased the property to Kennecott. From 2004 through 2006, Kennecott conducted extensive exploration of the Whistler region, including geological mapping, soil, rock and stream sediments sampling, ground Induced Polarization survey, and the evaluation of the Whistler gold-copper occurrence with fifteen core boreholes (7,948m) and reconnaissance core drilling at other targets in the Whistler region (4,184m). Over that period Kennecott invested over $6.3 million in exploration.
In June 2007, Geoinformatics announced the conditional acquisition of the Whistler Project as part of a strategic alliance with Kennecott.
From 2007 through 2008, Geoinformatics drilled twelve holes totaling 5,784m on the Whistler Deposit and six holes totaling 1,841m on other exploration targets in the Whistler area. Drilling by Geoinformatics on the Whistler Deposit was done to infill the deposit to sections spaced at 75m and to test for the north and south extensions of the deposit. Exploration drilling by Geoinformatics in the Whistler area targeted geophysical anomalies in the Raintree and Rainmaker areas, using the same basic porphyry exploration model as Kennecott.
In 2009, Kiska was formed by the merger of Geoinformatics and Rimfire Minerals Corporation. In total, Kiska completed 224 line-km of 3D Induced Polarization geophysics, 40 line-km of 2D IP geophysics, 327 line-km of cut-line, geological mapping on the 3D IP grid, detailed mapping of significant Au-Cu prospects, collection of 109 rock samples and 61 soil samples, 8,660m of diamond drilling from 23 drillholes (all greater than 200m in total length), petrographic analysis of mineralization at Island Mountain, a preliminary review of metallurgy at the Whistler Resource, and metallurgical testing of mineralization from the Discovery Breccia at Island Mountain. In August of 2010, Kiska delivered a report to Kennecott summarizing the results of the completed Trigger Program. In September of 2010, Kennecott informed Kiska that it would not exercise its back-in right on the Whistler Project and hence retained a 2% NSR on the property.
From this point forward, Kiska continued to drill and explore the Whistler Project for the duration of the 2010 and 2011 field seasons. The majority of this work included shallow grid drilling (25m to 50m top of bedrock drilling) in the Whistler area (also referred to as the Whistler Corridor), conventional step-out drilling from prospects in the Whistler area, step-out drilling at the Island Mountain Deposit, an airborne EM survey of the Island Mountain area, reconnaissance drilling at Muddy Creek, and minor infill drilling at the Whistler Deposit, followed by the publication of an updated resource estimate.
Geological Setting, Mineralization and Deposit Types
Geological Setting
The Whistler Project is located in the Alaska Range. The Alaska Range is a continuation of the Pacific Coastal Mountains extending in an arc across the northern Pacific, and represents a long-lived continental arc characterized by multiple magmatic events ranging in age from about 76 Ma to 30 Ma and associated with a wide range of base and precious metals hydrothermal sulphide mineralization. The geology of the Whistler Project is characterized by a thick succession of Cretaceous to early Tertiary (ca. 97 to 65 Ma) volcano-sedimentary rocks intruded by a diverse suite of plutonic rocks of Jurassic to mid-Tertiary age.
Two main intrusive suites are important in the Whistler Project area:
| ● | The Whistler Igneous Suite comprises alkali-calcic basalt-andesite, diorite and monzonite intrusive rocks with an age of approximately 76 Ma with restricted extrusive equivalent. These intrusions are commonly associated with gold-copper porphyry-style mineralization. |
| ● | The Composite Suite intrusions vary in composition from peridotite to granite and their ages span from 67 to about 64 Ma. Gold-copper veinlets and pegmatitic occurrences are characteristics of the composite plutons (e.g. the Mt. Estelle prospect, the Muddy Creek prospect). |
GoldMining acquired the Whistler Project for its potential to host magmatic hydrothermal gold and copper mineralization. Magmatic hydrothermal deposits represent a wide clan of mineral deposits formed by the circulation of hydrothermal fluids into fractured rocks and associated with the intrusion of magma into the crust.
Mineralization and Deposit Types
Exploration on the Whistler Project by Kennecott, Geoinformatics and Kiska has identified three primary exploration targets for porphyry-style gold-copper mineralization. These include the Whistler Deposit, Raintree Deposit, and the Island Mountain Deposit. The porphyry deposits in the Whistler area share similar styles of alteration, mineralization, veining and cross-cutting relationships that are generally typical of porphyry systems associated with relatively oxidized magma series (A- and B-type quartz vein stockwork, chalcopyrite-pyrite mineralization assemblage, presence of sulphates, core of potassic alteration with well-developed peripheral phyllic alteration zones) and well developed airborne magnetic and Induced Polarization chargeability/resistivity anomalies.
The Whistler-Raintree and Island Mountain areas also host multiple porphyry prospects defined by drilling, anomalous soil samples, alteration, veining, surface rock samples, IP chargeability/resistivity anomalies, airborne magnetic anomalies and airborne electromagnetic anomalies. These include the Raintree North, Rainmaker, Round Mountain, Puntilla, Snow Ridge, Dagwood, Super Conductor, Howell Zone and Cirque Zones.
Island Mountain exhibits a different style of alteration, veining and sulphide mineralization. Principally the occurrence of pyrrhotite and arsenopyrite associated with Au-Cu mineralization, strong sodic-calcic alteration, lack of significant sulphates, minor hydrothermal quartz and weak to insignificant phyllic alteration. For these reasons, the porphyry system at Island Mountain may belong to the “reduced” subclass of porphyry copper-gold deposits.
The Muddy Creek area represents an additional exploration target with the potential to host a bulk tonnage, intrusion-related gold deposit. Exploration by Millrock Resources Inc. on claims directly adjacent to the Muddy Creek area, which are geologically analogous, have returned encouraging preliminary results. Like Island Mountain, the Muddy Creek mineralization is distinct from the Whistler Porphyry systems and shares more similarity with intrusion related gold systems characteristic of the Tintina Gold Belt. The Muddy Creek prospect may also share geological similarities with the Korbel deposit owned by Nova Minerals Limited located 12 miles north. The Muddy Creek prospect may also share geological similarities with the Korbel deposit owned by Nova Minerals Limited located 12 miles north. The intrusive complex at Muddy Creek is predominantly monzonitic grading to more mafic marginal phases, yet is generally more felsic in composition relative to the diorites of the Whistler area. Mineralization is restricted to sheeted vein zones with narrow millimeter scale veinlets and pegmatitic veinlets of quartz, feldspar, tourmaline and sulphides that include arsenopyrite, minor chalcopyrite and pyrite-pyrrhotite. Gold mineralization is largely confined to the minute veinlets whereas the intervening intrusive rocks are largely unaltered and unmineralized.
We will apply geologic search criteria to our property scale exploration programs to detect geological attributes similar to the recent discovery of the RPM prospect made by Nova Minerals Limited, located 7 miles southeast of Muddy Creek.
Exploration
Prior to 2022, we had not completed exploration work at Whistler since acquiring the Whistler Project. The last previous exploration drilling was conducted by Kiska in 2011. Our strategy is to enhance and grow the value of our asset base, with a focus on exploring to grow the in situ Mineral Resource estimate and to advance mining, environmental and heritage studies on the Whistler Project towards delineation of a compelling business case optimizing bulk mineable near surface deposits. On June 30, 2022, we submitted an APMA to the ADNR in order to commence exploration field work activities in 2023. On September 22, 2022, the ADNR approved Multi-Year 2022-2026 Exploration and Reclamation Permit Number 2778 for Hardrock Exploration – Skwentna River – Yentna Mining District, and in addition also approved Reclamation Plan Approval Number 2778. Planned field work and studies comprises an initial two-year work program over 2023-2024 with the objective to consider initiating a PEA, pending exploration results, at the end of that period. Work conducted on the Whistler Project during 2022 comprised of identification and engagement with key business partners and subject matter expert consultants, stakeholder and community consultation, assessment of the condition of the existing Whistler camp, initial environmental baseline data collection, and desktop geological database validation, interpretation and analysis of potential drilling targets. The Whistler Multi-Year 2022-2026 Exploration and Reclamation Permit allows us to conduct exploration including drilling, operate and maintain a camp including storage of fuel, and to transport people, equipment and consumables to the Whistler Project.
Drilling
A total of 70,247m of diamond drilling in 257 holes has been completed on the Whistler Project by Cominco, Kennecott, Geoinformatics and Kiska from 1986 to the end of 2011. Of these drill holes, 21,132m in 52 holes have been drilled in the Whistler Deposit area, 20,479m in 94 holes have been drilled in the Raintree area and 14,410m in 36 holes comprise the Island Mountain resource area. There are 14,226m in 75 holes in areas outside the three resource areas.
Sampling, Analysis and Data Verification
There is no available documentation about sampling and analysis by Cominco. Previous operators Kennecott, Geoinformatics, and Kiska used industry standard practices to collect, handle and assay soil, rock and core samples collected during the period 2004-2011. These procedures are documented in detailed reports describing pertinent aspects of the exploration data collection and management.
All historic assay samples were assayed at either the Alaska Assay Laboratory (2004 and 2009) in Fairbanks, Alaska, or the accredited ALS-Chemex laboratory in Vancouver, British Columbia for all other years. Sample preparation was accomplished in Alaska, either at the Alaska Assay Lab or ALS-Chemex preparation lab in Anchorage, Alaska. Samples were assayed for gold by fire assay and a suite of elements including silver and copper by aqua regia or multi-acid digestion and inductively coupled plasma atomic emission spectroscopy. Operators Kennecott, Geoinformatics, and Kiska used industry standard quality control practices during exploration at Whistler. The S-K 1300 Report discloses that analysis of the QA/QC data indicates the assay data is of sufficient quantity and quality for resource estimation.
A site visit was conducted on September 14, 2022, by Sue Bird, the author of the S-K 1300 Report. No observations contradicting historic published information were made. The assay database did not have certificate numbers attached to the sample IDs, this was accomplished by the author of the S-K 1300 Report to the extent possible. Certificate checks revealed some minor errors which were corrected prior to resource modeling. Not all assay data in the database is fully supported by certificates and QA/QC. However, the percentage of data fully supported by certificates and QA/QC is consistent with similar projects that have the majority of drilling completed before 2010 and have undergone several changes in ownership. The S-K 1300 Report disclosed that the assay database is determined to be of sufficient quality and accuracy for resource estimation.
The Whistler Mineral Resource estimate and SK-1300 Report has not been updated subsequent to the 2023 drilling completed by us. On completion of the proposed exploration drilling program in 2024, and pending results of the program, geological modeling, Mineral Resource estimation, mine design and financial modeling may be initiated in late 2024 towards development of a mine scoping study (PEA).
Mineral Processing and Metallurgical Testing
Metallurgical testing had been carried out in three phases starting with the 2004/05 preliminary testing in Salt Lake City under the general supervision of Kennecott and culminating in the two phases under Kiska conducted at G&T Laboratories in Kamloops during 2010 to 2012.
Whistler Deposit preliminary metallurgical testing included gravity concentration or flotation to recover the copper and gold. From the metallurgical testing results and subsequent analysis, it appears that the Whistler Deposit is metallurgically amenable to a conventional flotation route to produce saleable high quality copper concentrates with gold credits, despite the low head grade, and that the levels of recovery and upgrade for both copper and gold are relatively insensitive to feed grade. We believe that there are no processing factors or deleterious elements that could have significant effect of potential economic extraction.
The preliminary testing indicated that the Island Mountain material tested is amenable to copper recovery by flotation and that the gold is relatively free milling. The results indicate that in the range of 90% of the potential gold may be recoverable by either whole ore leaching or a combination of flotation and leaching of the tailings. Further flotation work is expected to improve both potential copper and gold recoveries to concentrate.
For both deposits further metallurgical development and assessment work is required to develop the best flowsheet with respect to capital and operating costs, metal recoveries and overall economics.
As of the date hereof, no metallurgical testing has been carried out on rocks from the Raintree West Deposit, however, given the similarities in geological setting, host rock, mineralization and alteration between Raintree West Deposit and the Whistler Deposit, it has been assumed by GoldMining that metallurgical processes and metal recoveries determined for the Whistler Deposit are a reasonable approximation for the Raintree West Deposit at this time.
Metal recoveries reported for the Whistler Project resource estimate include 83% for copper, 70% for gold and 65% for silver with silver grades below 10 g/t and 0% for silver grades above 10 g/t.

2023 Exploration and Drilling Update
Our initially planned exploration programs over the 2023 and 2024 field seasons consists of up to 10,000-meters of core drilling, which is reduced from the initial target of 15,000 meters drilling, in order to allow us to determine actual costs of drilling while it re-established filed operations. Additional surface exploration may include soil geochemical sampling and geophysical surveying, geological data processing and interpretation, and collection of mine planning and mineral processing information including metallurgical, geotechnical and hydrogeological data. Environmental baseline data collection, as well as archaeological and heritage land use studies were also initiated in 2023, with on-ground archaeological surveys expected to be initiated in 2024. We have also engaged in stakeholder consultation with respect to both the present and ongoing exploration activity and the potential future mine development of the Whistler Project.
On May 30, 2023, we announced that we mobilized field teams to execute our 2023 exploration program at the Whistler Project (the “2023 Program”). On August 21, 2023, we announced that drilling had commenced under the 2023 Program.
In 2023, four confirmatory drill holes were completed for a total of 2,234 meters at the Whistler Project from mid-August to mid-November, at which time the drilling program was paused for a winter break. On January 16, 2024, we announced the results from these initial four confirmatory drill holes.
The HQ and NQ diamond drill core from the 2023 Program were logged and sampled at the Whistler field camp facility, supervised by qualified geologists (P.Geo. designation) from our lead exploration consultant, Equity Exploration Ltd., and supervised by our QP, Tim Smith (MSc., P.Geo.) Geologists marked out samples for assay after logging the drill core, predominantly at the maximum sample composite length of 2 meters in length. A minority of samples were cut at shorter intervals, at a minimum sample length of 0.5 meters, to honor lithological and alteration contacts logged by the geologists. All drillholes were systematically sampled from top of bedrock to bottom of hole, excepting the top sections of drill holes comprising unconsolidated sediments (soil, colluvium, alluvium). Sample tags were inserted into the core boxes and the core was photographed wet and dry, before being cut lengthways in half with a diamond saw. One half of the core was submitted for assay, one half was retained in core boxes at the Whistler site. A total of 1149 samples of half core were collected in total and the samples were sent toindependent certified assay laboratory Bureau Veritas North America Ltd. located in Fairbanks, AK, for processing, where samples were dried then crushed to 70% passing 10 mesh, then a 250 gram split was pulverized to 90% passing 150 mesh. Bureau Veritas then transported the processed sample pulps to its assay laboratory in Vancouver, Canada. All samples were analyzed for 45 elements, including copper and silver, using a 4-acid digestion followed by ICP-MS determination (method MA200). Gold analyses were determined by 30g fire assay with AAS finish (method FA430) which is considered to provide a total assay for gold. A total of 1149 assays were accepted into the Whistler drilling assay database, following passing of standard QAQC protocols.
On January 16, 2024, we announced initial results from the first three drill holes from the 2023 Program. These included the following. Reported grades are un-cut, and intercept lengths represent a subset of the true width of the Whistler Deposit.

The 2023 Program comprised four confirmatory drill holes in total: WH23-01 to WH23-04. Drill holes WH23-01 and WH23-02 targeted the southeast and southwest extents of the Whistler Deposit, respectively. WH23-03 was drilled at a steeper angle to provide additional geological data from the southern portion of the ‘high-grade core’ and to test for extensions below the base of the current resource model however, drilling was terminated prematurely due to freeze-up of the water supply at the onset of winter conditions. We will attempt to re-enter and deepen the drill hole in 2024 to explore the depth extents of the Whistler mineral system. A fourth confirmatory drill hole, WH23-04 was drilled at the Raintree South target located one kilometer south of the Whistler Deposit, bringing the 2023 Program total to 2,234 meters drilled. While the drill hole successfully intersected porphyry intrusive rocks and thereby confirmed the geophysical modelling and targeting methodology, core logging indicates weak to absent veining and alteration. Assay results are currently pending as of date of publication; however, we are not expecting that the LSP drilled to date has intersected mineralization. For the first time at the Whistler Project, all drill holes incorporated core orientation surveying, thereby providing structural geometry and geotechnical data. We currently expect that the drill core from the 2023 Program, once all processed, should provide updated information for advancing mineralogical and geometallurgical test work in the future.
The following map sets forth the location of the Whistler deposit drilling with gold and copper histograms plotted (left and right respectively; see legend). Drill traces for the 2023 drill holes are shown in bold (with prefix ‘WH023’) and gold and copper assay histograms are highlighted. Drilling is overlain on a geological interpretation of the host diorite porphyry (cut at 200 meters below surface) to illustrate the overall geometry of mineralized porphyry phases (pale purple) and non-mineralized late-stage porphyry phases (darker purple).
The Whistler Deposit is hosted within the Whistler Intrusive Suite, a composite suite of diorite stocks and dykes with clear cross-cutting relationships that divide the suite broadly into an early Main Stage Porphyry (“MSP”), a later Intermineral Porphyry Suite (“IMP”) and a late intrusive phase referred to as Late Stage Porphyry (“LSP”). Gold and copper mineralization is characterized by abundant disseminated sulphide and quartz + sulphide vein stockworks (including classic porphyry diagnostic ‘A’, ‘B’, ‘D’, and ‘M’ type veins), and potassic alteration which is variably overprinted by later phyllic alteration. The early stage MSP suite is most strongly altered, veined and mineralized, with the IMP being less intensely altered and veined but remaining consistently mineralized, and the late or post-mineralization LSP generally being below cutoff grade or unmineralized.
We are working to delineate the geometry, extents and continuity of the MSP and IMP suites, which serves to focus drilling on opportunities to expand mineralization where the potentially mineralized porphyry phases remain under-explored. In addition, the technical team has identified the presence of a robust core of higher-grade mineralization within the Whistler Deposit that correlates with intense alteration and veining within the MSP. Optimizing the geological model to improve confidence in the delineation of the MSP is a key focus of the 2024 drilling program as it will improve confidence in distribution and continuity of higher-grade zones within the Whistler Deposit.
We plan to re-commence the remainder of the previously announced approximate 10,000 meter drilling program at the Whistler Project at the start of the 2024 summer field season.
