Altan Rio (AMO) Builds on Southern Cross Project Consolidation Exercises Option Agreement on E77/2691

Vancouver, British Columbia–(Newsfile Corp. – February 22, 2023) – Altan Rio Minerals Limited (TSXV: AMO) (“Altan Rio Minerals” or the “Company”) is pleased to announce the execution of the Option over the E77/2961. (See Announcement of the Company dated September 9, 2021).

• Altan Rio Minerals completes the option to purchase 90% interest in large exploration license application located between Southern Cross and Bullfinch in Western Australia prospective for gold, nickel, and other commodities.
• Tenement has minimal sustained exploration for gold or nickel and contains numerous evidence of historic small gold mining activities.
• Presence of what appear to be fertile host rocks for nickel sulphides within the Tenement (both komatiite-hosted and layered mafic intrusion related) have been previously identified.
• A comprehensive Surface Mapping and Sampling Program is planned to commence early March with completion expected the second Quarter 2023.
• E77/2691 is located between known nickel sulphide locations (Forrestania nickel deposits to the south and Trough Well to the north).

New E77/2691 more than doubles Altan Rio’s tenement area in the Southern Cross region

Gold Potential

Altan Rio will hold the one of the largest tenure over the Frasers-Corinthian Shear Zone (FCSZ) with a landholding of 139.6km2. The FCSZ which is covered by Altan Rio’s North-South tenement holdings, is a defined gold-rich bearing structure which is host to gold mineralisation along its entire length with multiple high-grade ore bodies including Copperhead (1.55 Moz), Frasers (748 Koz.), Golden Pig (502Koz), Hopes Hill (214 Koz), Corinthia (300 Koz) and Pilot (54 Koz). (See Announcement of the Company dated September 9, 2021).

A review of historic exploration reports has identified a significant number of targets have been generated. These targets are being scrutinised, leveraging these reports and knowledge of Altan Rio’s geology team, a surface mapping and sampling program has been generated.

Nickel Potential

Altan Rio Minerals has completed a brief review of open file drill hole data to identify areas that have anomalous nickel assay results, and indications of nickel sulphide mineralisation.

The next phase of review will be to consider the geochemical and geophysical coverage of the Tenement. In this brief review the previously identified Robertsons and Gibney’s intrusive nickel-copper-PGE prospect was confirmed as being located within the Tenement. The prospect was subject to exploration in the early 2000s by Sons of Gwalia. Exploration identified a layered mafic-ultramafic intrusion with PGE anomalism on some of the boundaries and between layers internal to the intrusion. The basal contact, which is expected to be the most prospective area for nickel sulphides, is not well exposed, but appears to have been the subject of limited RAB drilling.

Transaction Details

• The option exercise price is $250,000 cash plus $250,000 worth of fully paid ordinary shares in Altan Rio Minerals calculated at a 30-day VWAP.
