Subsidiary Mari Minerals identifies copper mineralisation across 1.4 square kilometres after drilling 25,000 metres near Reko Diq; initial results show copper grades of up to 0.50%, with deeper exploration planned
Mari Energies Limited has announced a significant copper-gold discovery at the East Siah Diq (ESD-1) target in Chagai, Balochistan, following approximately 25,000 metres of exploration drilling conducted through its wholly owned subsidiary, Mari Minerals (Private) Limited.
In a disclosure submitted to the Pakistan Stock Exchange (PSX) on Friday, the company said drilling had identified porphyry copper-style mineralisation across an area of approximately 1.4 square kilometres, with initial assay results showing copper grades reaching 0.50% over substantial drilled intervals.
The discovery is located approximately 50 kilometres east of the Reko Diq copper-gold mine development project and 25 kilometres northwest of Nokkundi, in the Koh-i-Sultan area adjacent to the Siah Diq Project.
Mari Minerals, which holds multiple exploration licences in Chagai, completed the drilling programme in two phases, Phase 1A and Phase 1B, with vertical drill holes extending to approximately 500 metres.
According to the company, the mineralisation was encountered beneath approximately 100 metres of unconsolidated sediments, with drilling results indicating the presence of a new porphyry copper system.
The Phase 1A assay results included a 400.25-metre interval grading 0.50% copper and 0.11 grams per tonne of gold in drill hole ESD-1-DD-017.
Another drill hole, ESD-1-DD-011, returned 392.7 metres grading 0.45% copper and 0.14 grams per tonne of gold, while ESD-1-DD-016 recorded 404.2 metres at 0.43% copper and 0.12 grams per tonne of gold.
Further results included 408.4 metres grading 0.42% copper and 0.11 grams per tonne of gold in ESD-1-DD-015, and 406.6 metres grading 0.41% copper and 0.11 grams per tonne of gold in ESD-1-DD-007.
The company reported copper grades ranging from 0.04% to 0.50% across the 20 Phase 1A drill-hole intercepts, with gold grades ranging from 0.02 to 0.19 grams per tonne.
Molybdenum was also detected in the drilling results, with reported concentrations reaching 171 parts per million in one drill hole.
The company clarified that the reported intercepts represent the entire length of intersected bedrock without applying a minimum cut-off grade.
Assaying of the Phase 1B drill holes is currently underway and is expected to be completed during the first quarter of 2027.
Mari Energies said copper mineralisation at ESD-1 is primarily associated with chalcopyrite, accompanied by pyrite, while bornite has also been observed.
Molybdenum mineralisation associated with molybdenite was identified in selected drill holes, along with localised copper oxide minerals beneath the surface sediments.
The mineralisation is hosted within porphyritic diorite intrusive rocks, with geological observations identifying multiple intrusive phases and widespread hydrothermal alteration.
SGS Pakistan conducted sample preparation and assaying, while Mari Minerals implemented quality assurance and control procedures using certified reference materials, duplicates and blank samples.
The company said the mineralised system remains open below the current drilling depth of 500 metres, with the next exploration phase expected to investigate deeper extensions down to 1,000 metres.
The programme will also include additional step-out drilling to assess the extent of mineralisation beyond the areas explored so far.
An initial geological model and resource estimate will be developed using the results of both drilling phases.
However, Mari Energies cautioned that the discovery remains at the exploration stage and that further drilling, metallurgical testing, geological interpretation and technical studies will be required to establish the scale, grade continuity, economic significance and development potential of the mineralisation.
The company also clarified that the results do not yet constitute a mineral resource or reserve.
The technical findings were reviewed and verified by Dr John Mortimer of JM Geoscience Pty Ltd, a qualified geoscientist with more than 40 years of relevant experience, including porphyry copper exploration, in accordance with the disclosure principles of National Instrument 43-101.
