Lion Copper & Gold files an NI 43-101 report confirming large indicated and inferred copper resources at the Bear Deposit, adjacent to its Yerington Copper Project.

Rhea-AI Filing Summary

LION COPPER & GOLD CORP. (LCGMF) announced the filing of an independent NI 43-101 Technical Report supporting the maiden Mineral Resource Estimate for its Bear Deposit in the Yerington Copper District in Nevada. The report is dated September 14, 2026, with an effective date of July 21, 2026.

The Bear Mineral Resource Estimate outlines an Indicated Resource of 6.71 billion pounds of contained copper (1,064 Mt at 0.29% Cu) and an Inferred Resource of 8.77 billion pounds (1,770 Mt at 0.22% Cu), using a 0.1% Cu cut-off for sulfide material. The company cautions that Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.

6 terms

NI 43-101 regulatory

"prepared in accordance with National Instrument 43-101 - Standards of Disclosure"

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.

Mineral Resource Estimate technical

"supporting the maiden Mineral Resource Estimate ("MRE") for the Company's Bear Deposit"

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.

Indicated Resource technical

"establishes an Indicated Resource of 6.71 billion pounds of contained copper"

An indicated resource is a quantity of minerals estimated from sample data with a moderate level of confidence—higher than a rough estimate but not as certain as a fully proven quantity. For investors, it signals a reasonable but still uncertain expectation that commercial extraction could be feasible; think of it like a well‑researched recipe where ingredients and amounts are likely correct but still need final confirmation before you start cooking or spending large sums.

Inferred Resource technical

"and an Inferred Resource of 8.77 billion pounds of contained copper"

An inferred resource is an early-stage estimate of how much mineral material may be present and its likely quality, based on limited sampling and basic geological patterns rather than detailed data. It matters to investors because it indicates potential upside but carries high uncertainty—like a rough hand-drawn map that hints at treasure but needs much more surveying and testing before anyone can count on its value for planning or valuation.

Definitive Feasibility Study financial

"advancing the Yerington Copper Project through Definitive Feasibility Study and permitting"

A definitive feasibility study is a detailed, near-final assessment that shows whether a proposed project—often a mine, infrastructure or major industrial venture—can be built and operated profitably. It combines precise engineering plans, realistic cost estimates, production schedules and risk analysis to give lenders and investors a clear picture of expected returns and potential pitfalls, like a full blueprint and budget that helps decide whether to greenlight financing and construction.

LME Grade A copper cathode financial

"planned to produce refined LME Grade A copper cathode for the domestic U.S. market"

Lion Copper Corp. Announces Filing of NI 43-101 Technical Report for
Bear Deposit

YERINGTON, Nevada - September 14, 2026 - Lion Copper Corp. (CSE: LCU) (OTCQB: LCGMD) ("Lion" or the "Company") is pleased to announce that it has filed the independent technical report supporting the maiden Mineral Resource Estimate ("MRE") for the Company's Bear Deposit, located within the Yerington Copper District in Lyon County, Nevada.

The technical report, titled "NI 43-101 Technical Report of the Bear Deposit" and dated September 14, 2026, with an effective date of July 21, 2026 (the "Technical Report"), was prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") and supports the Bear MRE previously announced by the Company on August 4, 2026.

The Bear MRE establishes an Indicated Resource of 6.71 billion pounds of contained copper (1,064 Mt @ 0.29% Cu) and an Inferred Resource of 8.77 billion pounds of contained copper (1,770 Mt @ 0.22% Cu), further demonstrating the scale and long-term development potential of the broader Yerington Copper District.

John Banning, Chief Executive Officer of Lion Copper Corp., commented:

"The filing of the Bear Technical Report represents another important milestone for Lion and provides the comprehensive technical basis supporting the maiden Mineral Resource Estimate announced in August. Bear has materially expanded the scale of our copper endowment and reinforces our view of the Yerington Copper District as one of the largest undeveloped copper districts in the United States.

"Our immediate focus remains on disciplined execution at the Yerington Copper Project, where the Definitive Feasibility Study and permitting programs continue to advance. Over the longer term, Bear provides significant additional optionality immediately adjacent to Yerington and the potential to leverage the infrastructure being developed for the project."

The maiden Bear MRE was previously announced by Lion on August 4, 2026. The Technical Report provides the supporting geological, drilling, estimation and technical information underlying the MRE, together with the assumptions and considerations used by the Qualified Persons in determining reasonable prospects for eventual economic extraction.
