About Rio Grande
Rio Grande Resources is a gold and silver project situated on a ~3,000+-acre drill-readyproperty located in the Black Range of Sierra County, New Mexico. It’s home to three historicmines: Ivanhoe, Emporia, and Little Granite, consisting of 147 unpatented BLM (Bureau of Land Management) mining claims and 2 patented Ivanhoe and Emporia lode mining claims. Each mine produced high-grade gold and silver during full-time operations over a century ago.
Rio Grande was incorporated in July 2024 and became a public company on January 31, 2025, following a corporate reorganization (a “Plan of Arrangement”) by Foremost Clean Energy Ltd. In this transaction, Foremost spun out its Winston Gold & Silver Property into the new stand alone company, Rio Grande. In exchange for the asset, Foremost’s shareholders received two shares of Rio Grande for each share of Foremost they owned, and Foremost itself, at the time, an approximate 19.95% ownership stake in the new company, making it the largest shareholder.

Drill Ready Targets
Including on both patented and unpatented claims
Property Features
The area was a past major producer with a current strong potential for district-scale discovery
Gold & Silver Market
Strong macro-economic trends has drove gold to all time highs in 2025 and silver to levels it hasn’t seen since the 1908’s
Favourable Geology
The mineralization is of the well-documented epithermal type (close to the surface) within the Paymaster Fault, a structural trend known for historic gold deposits
Project History
High grade deposits of silver and gold were mined over 100 years ago, but ceased due to the decline in the price of silver and gold; little or no modern exploration has occurred since
Promising Potential
Samples have returned 66.5g/t au and 4,610 g/t ag in 2021 within the main geological feature, the Rio Grande Rift, which currently hosts several past and present silver mines
Precious Metals Market Current Overview
Gold and silver are experiencing a
powerful bull market, dramatically
outperforming major asset classes like the S&P 500 and Bitcoin.
Gold reached it’s all-time high to date on September 5, 2025 hitting US$3,599.61
Silver surged above $40 an ounce for the first time since 2011
Projects
The Little Granite Gold Mine
This past producing gold mine is 100% owned by Rio, consisting of 4 lode mining claims. A limited re-sampling program included peak values of 66/5 g/t gold and 2,940 g/t silver Multiple site visits suggest the primary vein widens to more than 4 m (12 ft) true width, at depth. The main vein has been traced for over 200 metres by past drilling and remains open along strike and at depth.
Did you know?
Past-sampling results at THE LITTLE GRANITE included 26.8 g/t gold and 1,670 g/t silver? The main vein has been traced for over 200 meters by past drilling and remains open along strike and at depth.
Projects
The Ivanhoe and Emporia Mine
The Ivanhoe and Emporia are past producing gold-silver mines consisting of 2 patented lode claims, providing exclusive ownership of the land and its resources (not owned by the government). Results from a sampling program returned peak values of 26.8 g/t gold & 1670 g/t silver from Ivanhoe, and 46.1 g/t gold and 517 g/t silver from Emporia. The Ivanhoe Emporia Vein structure is 3-5m wide at surface and historically developed to a depth of 384 feet.
Did you know?
Patented claims gives exclusive ownership of the land and its resources, while unpatented mining claims may provide access and use the land to extract minerals, but the government still owns the land?
