"updated technical report titled "NI 43-101 Technical Report for the San Francisco Project"
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.

SEDAR+ is Canada’s centralized online system where publicly traded companies submit required regulatory documents such as financial reports, prospectuses and disclosure statements. It gives investors a single, searchable place — like a public library or online filing cabinet — to check a company’s official records for transparency, compare performance, and verify material information before making investment decisions.
mineral resource estimatetechnical
"There are no changes to the mineral resource estimate previously disclosed"
A mineral resource estimate is a calculated approximation of how much metal or mineral material likely exists in a particular deposit and where it sits underground, similar to estimating how many cookies are in a jar by peeking at the layers. It matters to investors because it provides a data-based starting point for judging a project's potential value, future production and risks, while not guaranteeing recoverable or profitable amounts.
