- Reko Diq is located in the Tethyan Belt, a tectono-magmatic and metallogenic belt that extends from Eastern Europe to Southeast Asia. - The Reko Diq project area is comprised of 14 separate Miocene age porphyry intrusions. - The current conceptual mine plan is based on 4 porphyry deposits within the Reko Diq project area (H13, H14, H15 and H4). - District is highly prospective with other porphyry clusters providing long-term upside potential.The H14 and H15 porphyry systems represent a cluster of 4 different porphyry intrusions emplaced at different times with variable Cu-Au grades and tenor. The highest Cu-Au grades (>0.60%Cu and 0.40g/t Au) are associated with intense potassic alteration in the early and 2nd phase porphyry intrusions (PFB1 and PFB2) truncated by late stage, weakly mineralized PFB3 and late-mineral barren PFB4 porphyry intrusions forming a low grade core in both H14 and H15 deposits.The early and inter-mineral porphyry intrusions (PFB1, PFB2) and adjacent host rocks represent intense network of EB (early biotite) and A-B style veins of quartz, K-feldspar and magnetite (terminology of Gustafson and Hunt, 1975). The main ore stage Cu-Fe-sulfides consisting of disseminated and vein hosted chalcopyrite + bornite + pyrite ± molybdenite ± digenite are associated with intense K-silicate alteration in and adjacent to the early porphyry phases. The late-stage PFB3 porphyry intrusion generally post date all the early A-B veins and main ore stage sulfide mineralization but is genetically linked to the D-vein phase representing a late ore stage Cu-Fe-sulfides. The H15 complex has locally developed fine grained pyrite + chalcopyrite overgrown by bornite ± covellite in association with intense quartz + sericite ± clay alteration indicating a high sulfidation state within iron poor sandstone and conglomerate units similar to that documented in quartzite host rocks in Bingham, Utah.
