ISLAMABAD, November 13, 2026: Mari Energies Limited has announced a copper-gold discovery at its East Siah Diq (ESD-1) exploration site in Chagai district, Balochistan, following extensive drilling conducted through its wholly owned subsidiary, Mari Minerals (Private) Limited.
The announcement was made by MariEnergies Managing Director and CEO Faheem Haider at the Pakistan Mineral Investment Forum 2026. The company also disclosed the development to the Pakistan Stock Exchange (PSX).
Located approximately 50 kilometres east of the Reko Diq copper-gold project and 25 kilometres northwest of Nokkundi, the discovery lies in the mineral-rich Koh-i-Sultan area.
According to the company, around 25,000 metres of exploration drilling have been completed in two phases, with boreholes reaching depths of 500 metres. The drilling identified porphyry-style copper mineralisation beneath approximately 100 metres of overburden across an area of 1.4 square kilometres.
Haider described the discovery as an important milestone in the company’s mineral exploration programme, saying it reinforced confidence in Chagai’s geological potential.
He said further exploration and technical studies would focus on determining the scale and development potential of the deposit.
Laboratory analysis of samples collected during the second drilling phase is underway, with results expected in the first quarter of 2027.
MariEnergies plans additional drilling to depths of up to 1,000 metres to assess whether mineralisation extends further underground. The company will also examine the deposit’s lateral extent and prepare an initial geological model and resource estimate.
However, MariEnergies clarified that the findings do not yet constitute a formally established mineral resource or reserve. Further geological studies, metallurgical testing and resource assessments will be required to determine the discovery’s commercial viability.
The company said it would provide further updates as exploration and technical evaluations progress.
