Pakistan’s mineral exploration sector has received a boost after Mari Energies announced a copper-gold discovery in Balochistan. The newly identified mineralisation lies around 50 kilometres east of the Reko Diq mining project.
The discovery was made by Mari Minerals, a wholly owned subsidiary of Mari Energies Limited. The exploration site, known as East Siah Diq (ESD-1), is located in the Koh-i-Sultan area of Chagai district.
According to the company’s disclosure to the Pakistan Stock Exchange on Friday, November 13, exploration drilling has identified copper mineralisation across approximately 1.4 square kilometres.
25,000 Metres of Exploration Drilling Completed
Mari Minerals has completed around 25,000 metres of drilling through two exploration phases. Each drill hole reached a depth of approximately 500 metres.
The findings revealed porphyry-style copper mineralisation beneath nearly 100 metres of surface material. Researchers also identified minerals associated with copper, including chalcopyrite, pyrite and bornite.
Meanwhile, some drill holes also showed traces of molybdenum and copper oxide minerals.
The company has compiled laboratory results from its first drilling phase. However, testing of samples from the second phase remains underway and is expected to finish in the first quarter of 2027.
Further Drilling to Explore Deeper Deposits
Mari Energies plans to expand exploration at the site through deeper drilling. The next phase will examine mineralisation at depths of up to 1,000 metres.
The company also intends to prepare an initial geological model and resource estimate using results from both completed drilling phases.
However, the discovery does not yet represent a confirmed mineral resource or commercially recoverable reserve. Further drilling, laboratory testing and technical studies will determine its actual scale and economic potential.
Discovery Adds to Chagai’s Mineral Potential
The East Siah Diq discovery adds another development to Chagai district’s growing copper-gold exploration activity.
Its location near Reko Diq also highlights the mineral potential of the wider region. Nevertheless, further assessments will establish whether the deposits can support future commercial development.
Mari Energies has said it will share additional updates as exploration advances and more laboratory results become available.
