Indicated Resources Contain 29.9 Moz AgEq 1 at 519 g/t AgEq and Inferred Resources Contain 27.9 Moz AgEq at 369 g/t AgEq

VANCOUVER, BC , Sept. 14, 2026 /CNW/ -- Outcrop Silver & Gold Corporation (TSX: OCG) (OTCQX: OCGSF) (DE: MRG) ("Outcrop Silver" or the "Company") is pleased to report the results of an updated mineral resource estimate (the " Updated MRE ") for its 100%-owned Santa Ana primary silver project in Colombia (" Santa Ana " or the " Project ").

HIGHLIGHTS

The Updated MRE includes: Indicated resources with 29.9 million ounces (" Moz ") silver-equivalent 1 (" AgEq "), comprised of 21.7 Moz silver and 0.104 Moz gold; and

Inferred resources with 27.9 Moz AgEq, comprised of 20.1 Moz silver and 0.098 Moz gold.

Contained AgEq ounces in Indicated resources in the Updated MRE increased 23.5% compared to the maiden mineral resource estimate for the Santa Ana Project outlined in a technical report dated June 8, 2023 (the " Maiden MRE "). Inferred resources increased 106.3% to 27.9 Moz AgEq.

Mineral Resource classification in the Updated MRE applied a more rigorous standard than the Maiden MRE, including constraining resources based on reasonable prospects for eventual economic extraction (" RPEEE ") and mineable shape optimization (" MSO ").

The Updated MRE is based on 130,006 metres (" m ") of total drilling in 646 holes and uses a cut-off grade of 95 g/t AgEq for the Santa Ana and Los Naranjos veins and 130 g/t AgEq at all other veins.

The Updated MRE confirms the very high-grade nature of the Santa Ana project. The average grade of the Indicated resources is 518.7 g/t AgEq, of which 72.6% is from silver and 27.4% is from gold. Mineralization is contained in 13 primary vein systems, which range in average Indicated grade from 197.4 to 854.8 g/t AgEq.

Significant upside remains from exploration. There are twelve known ve
