GLOSSARY OF MINING TERMS

The following are abbreviations and definitions of certain terms commonly used in the mining industry and this document:

**1300 of Commission Regulation S-K.**Subpart 1300 of Regulation S-K governs the disclosure requirements for registrants involved in mining operations.

**Cored holes.**Drilled using specialized hollow bits to extract core samples which provides geologists and exploration companies with detailed, representative data on subsurface geology, aiding in decisions to start or abandon mining operations.

Cu-Ag zone. An area where both copper (Cu) and silver (Ag) are found together in economically significant concentrations, often within sediment-hosted deposits, hydrothermal veins, or skarns.

Cu-Mo zone. A geological area or deposit containing commercially valuable concentrations of both copper (Cu) and molybdenum (Mo) minerals, often associated with porphyry deposits.

**Cutoff grade.**The minimum grade (quality) of ore that is considered economically viable to extract and process from a mineral deposit.

Down-hole histogram. Tools for visualizing and analyzing data collected from drill holes.

Felsic intrusive phases. Bodies of igneous rock that formed from slowly cooling, silica-rich magma beneath the Earth’s surface.

**HQ.**Core diameter (around 63.5 mm).

**In-situ grade.**Refers to the concentration of valuable minerals within an ore body that is targeted for extraction using in-situ recovery (ISR) techniques, such as solution mining, before the ore is physically removed from the ground.

Lode mining claims. A mining claim where valuable minerals are found within a vein, lode, or ledge, typically embedded in hard rock.

**Ma.**A milliampere (symbol: ma) is a submultiple of the SI base unit of electrical current, the ampere. It is defined as one thousandth of an ampere.

Mineralization. The geological process where economically important metals or minerals are deposited in a host rock, forming an orebody that can be mined for profit.

Mo zone. Refers to an area with a high concentration of Molybdenum (Mo) ore.

MoS2. Known as molybdenite, it is a key mineral in mining, found in low-grade porphyry deposits of molybdenum and copper.

Net smelter return. The revenue a mining company receives from selling processed minerals, minus the costs of transportation, smelting, and refining.

**NI 43-101.**Canada’s mandatory National Instrument for disclosure of scientific and technical information about mineral projects, establishing standards to protect investors and ensure information is accurate, consistent, and understandable.

NQ. Core diameter (around 47.6 mm).

**Ordinary kriging.**A widely used geostatistical method for estimating ore grades and mineral reserves by using a weighted average of nearby samples to predict values at unsampled locations.

PEA. A high-level, early-stage study that provides a first look at a mineral project’s potential economic viability.

Pit constraint. Any limitation or condition that must be satisfied when designing an open-pit mine to ensure safe and profitable extraction of ore.

Placer operations. Methods for extracting valuable minerals like gold, tin, and diamonds from unconsolidated deposits such as riverbeds and beach sands, where natural forces have concentrated them.

**Porphyry.**A type of igneous rock characterized by large crystals (phenocrysts) embedded in a finer-grained groundmass.

Qualified Person. An individual with a relevant professional degree and a minimum of five years of specific, relevant industry experience who is qualified to prepare and be responsible for the technical reports and public disclosures related to a mineral project.

RCV calculation. Determines revenue and investment within specific industries.

Rotary holes. Created using rotary drill rigs and are crucial for placing explosives to break up large sections of rock, facilitating mining operations.

**TRS.**A detailed document that provides a summary of material scientific and technical information about a mineral property.

Unorganized mining district. A designated area for mining that is not formally structured, managed, or administered in the same way as other organized districts, often characterized by a less formal legal framework and more ad hoc operations, particularly within historical records or for the general region of United States federal land.
