Karachi: Mari Energies Limited has announced a notable discovery of copper and gold at the East Siah Diq (ESD-1) target in Chagai, Balochistan, through its wholly owned subsidiary, Mari Minerals (Private) Limited. The announcement was made on November 13, 2026, in compliance with Section 96 of the Securities Act, 2015, and Clause 5.6.1(a) of the Pakistan Stock Exchange (PSX) Regulations.

The discovery is situated approximately 50 kilometers east of the Reko Diq copper-gold mine development project and 25 kilometers northwest of Nokkundi in the Koh-i-Sultan area. MariMinerals, which holds multiple exploration licenses in the region, conducted about 25,000 meters of exploration drilling at the ESD-1 target. This drilling was carried out in two phases, with all drill holes being vertical and extending 500 meters in length.

The geochemical assay results for Phase 1A, carried out by SGS Pakistan, indicate the presence of porphyry copper-style mineralization beneath roughly 100 meters of unconsolidated overburden sediments, covering an area of approximately 1.4 square kilometers. Assaying for Phase 1B is currently underway and expected to conclude in the first quarter of 2027.

According to information available from the Pakistan Stock Exchange (PSX), the drill holes at ESD-1 revealed copper percentages ranging from 0.04% to 0.50% and gold content between 0.02 g/t and 0.19 g/t. The most significant copper concentration was found in drill hole ESD-1-DD-017, with a recorded 0.50% copper and 0.11 g/t gold over a length of 400.25 meters.

Mari Energies Limited's discovery at East Siah Diq marks a significant milestone in its exploration efforts in Balochistan, potentially contributing to the region's mineral wealth and economic development. The ongoing assaying and analysis will further delineate the extent and commercial viability of the copper-gold deposits at this site.
