Key Terms

form 20-f, sedar+, mineral reserves and mineral resources, ni 43-101
4 terms
form 20-f regulatory
"filed its annual report on Form 20-F for the fiscal year ended December 31, 2025"
Form 20-F is the standardized annual disclosure that non-U.S. companies must file with the U.S. securities regulator when their shares are traded in the U.S.; it contains audited financial statements, a plain-language description of the business, management discussion, governance details and key risk factors. It matters to investors because it provides a consistent, comparable company “report card” and rulebook, helping buyers assess financial health, governance and risks before investing.
sedar+ regulatory
"with the U.S. Securities and Exchange Commission ... and on SEDAR+ in Canada"
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 reserves and mineral resources technical
"updated report on Mineral Reserves and Mineral Resources estimates as of December 31, 2025"
Mineral reserves are the portion of a mineral deposit that has been tested and shown to be commercially extractable with current technology and prices; mineral resources include reserves plus additional material that is geologically identified but not yet proven economic. Investors use reserves to gauge near-term production and cash flow, while resources indicate potential upside and longer-term growth—like knowing how much usable fuel is in the tank now versus how much might be reachable with further effort.
ni 43-101 regulatory
"prepared in accordance with Canadian National Instrument 43-101 ("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.
