Mineral Resource technical

"maiden Mineral Resource estimate"

A mineral resource is a naturally occurring concentration of minerals in the ground that is considered valuable and likely recoverable based on geological evidence and preliminary studies. For investors, it signals the potential size and worth of a deposit—like a marked treasure area on a map—while also carrying uncertainty about how much can actually be mined and at what cost, affecting project value and risk.

AuEq technical

"2.58 million ounces AuEq Indicated"

Indicated technical

"2.58 million ounces AuEq Indicated"

Indicated describes a medical use or patient group for which a drug, device, or treatment has been shown or authorized to work; it's like a label that says which problem the product is meant to fix. For investors, a new or expanded indication can directly change a product’s potential sales and market size, similar to a store adding a new aisle of goods that attracts more customers.

Inferred technical

"2.83 million ounces AuEq Inferred"

Inferred means a conclusion or piece of information drawn from available clues rather than directly observed or confirmed. For investors, an inference is like reading a weather forecast from cloud patterns: it helps form expectations about a company’s performance or risks when hard data is missing, but it carries uncertainty and should be weighed alongside verified facts.

NI 43-101 regulatory

"prepared in accordance with NI 43-101"

A Canadian regulatory standard that sets the rules for how mining and exploration companies must report mineral resources and reserves, requiring technical reports prepared or signed off by an independent, certified expert. It matters to investors because it creates a consistent, transparent “inspection report” for mining projects, making it easier to compare prospects, judge the reliability of claims, and assess geological and financial risk before investing.

CIM Definition Standards regulatory

"NI 43-101 and the CIM Definition Standards"

CIM Definition Standards are a set of rules used to classify and report quantities of minerals in a mine or exploration project, spelling out what counts as a measured, indicated, or inferred resource and what is considered a reserve. For investors, they provide a common yardstick so you can compare the size and reliability of mineral estimates across projects — like using the same recipe to judge how likely a cooking result will turn out as advertised.
