Cornerstone Capital Resources Inc. provided an update on its Bramaderos gold and copper joint venture in southern Ecuador in which it has a 12.5% interest carried by JV partner and project operator Sunstone Metals Ltd. through to the start of commercial production. The results from holes BMDD014 through 018 clearly show that higher grade mineralization occurs in sub-domains within the larger 1.1km long Brama-Alba system, and that these higher-grade domains extend to surface. The potential for Brama to host a substantial gold-copper porphyry system is being reinforced with ongoing drilling.

There is also potential for this system to extend significantly to adjacent targets Melonal and Playas. These areas are expected to be drill tested in Third Quarter and Fourth Quarter 2022 respectively. Assay results for drill holes BMDD014 through 018, and 26.

Drill holes BMDD014, 15 and 16 were drilled from the collar of hole BMDD008, towards the east, southeast, and south-southwest respectively. BMDD014 and 15 were drilled to test higher grade intrusive breccias previously drilled in hole BMDD008 and 008W1, which intersected 505.1m at 0.43g/t gold, 0.1% copper from surface, including 84.3m at 0.80g/t gold, 0.11% copper from 179.7m. Most of the mineralization in drill hole BMDD016 is also hosted in syn-mineral intrusion breccias.

Drill hole BMDD017 was drilled at the eastern end of the Brama porphyry system and drilled towards the southeast. It intersected a sequence of alternating syn-mineral diorite, late hornblende-quartz diorite, and minor intrusive breccia, with the upper 84m being well mineralized. The bottom 200m drilled mainly syn-mineral diorite with disseminated and vein hosted chalcopyrite, bornite and trace covellite and chalcocite.

The bottom 5.6m of hole 17 is well mineralized and it is planned to re-enter this hole and deepen it to test the possible extension of the deep mineralized zone. Four drill holes have been planned to test eastern extensions of the deposit and to test an undrilled magnetic target at depth just east of Brama. Drill hole BMDD018 was drilled between holes BMDD004 and BMDD017, at a shallow angle, and tested an interpreted domain of higher-grade mineralized porphyry near surface.

This zone was intersected in the upper 84m of the drill hole and was then disrupted by post-mineral dykes, and then passed into early host quartz diorite towards the southwest, consistent with other drill holes. The vertical extent of the higher-grade zone remains poorly tested and will be followed-up.
