MISTANGO CLOSES MCVITTIE PROPERTY ACQUISITION, INCREASING OMEGA PROPERTY AREA BY 60%

Mistango River Resources Inc. has closed its acquisition of the McVittie property immediately adjacent to its 100-per-cent-owned Omega gold project to the north.

McVittie property is now consolidated into the Omega gold project

McVittie is located in southern-central McVittie township in the Larder Lake mining division of Ontario, approximately 25 kilometres east of Kirkland Lake, Ont. McVittie comprises eight patents with surface and mining rights and is contiguous with the northern portion of Omega. The acquisition has increased Omega's property size from 257 hectares to 400 hectares.

Omega is central to the Cadillac/Larder Lake break consolidation strategy

Omega is a strategic growth asset in a multimillion-ounce gold district that is primed for consolidation -- the Cadillac/Larder Lake break (CLLB). Omega historically produced approximately 215,000 ounces grading 5.41 grams per tonne gold between 1926 and 1928 and between 1936 and 1947. Omega currently hosts an open-pittable resource, including a measured and indicated resource of 4.92 million tonnes grading 1.39 grams per tonne gold (219,800 ounces) and an inferred resource of 4.69 million tonnes grading 2.43 grams per tonne gold (365,400 ounces).

The prolific CLLB and the larger Kirkland Lake district host some of the highest-grade gold resources globally. Immediately adjacent to and surrounding Omega is Mag Silver's Larder project, which hosts a historical indicated resource of 5.13 million tonnes grading 2.39 grams per tonne gold (388,000 ounces) and a historical inferred resource of 6.89 million tonnes grading 4.21 grams per tonne gold (933,000 ounces). Near the town of Kirkland Lake, Ont. (30 kilometres west of Omega), the Cadillac break hosts Agnico Eagle's Macassa mine, one of the world's highest-grade gold deposits, which produced 279,384 ounces of gold at an average grade of 15.55 grams per tonne gold in 2024. Located 10 kilometres east of Omega, in the town of Virginiatown, the historical Kerr Addison mine produced 11 million ounces at nine grams per tonne gold and currently hosts an indicated resource of 69.2 million tonnes grading 1.5 grams per tonne gold (3.31 million ounces) and an inferred resource of 55.6 million tonnes grading 1.3 grams per tonne gold (2.36 million ounces). North of Omega and the CLLB, Agnico Eagle is developing its multimillion-ounce Upper Beaver deposit.
