Sunstone Metals (ASX:STM) is an ASX listed mineral exploration company discovering gold and copper in large porphyry deposits in Ecuador.

Sunstone currently has 2 main projects, the Bramaderos Gold-Copper Project in southern Ecuador and the El Palmar Gold-Copper Project in northern Ecuador.

The Bramaderos project is an incorporated joint venture between Sunstone and TSX:V listed Cornerstone Capital Resources (TSX.V:CGP). Sunstone owns 87.5% of La Plata Minerales (‘PLAMIN’) which holds the Bramaderos concession, and loan carries Cornerstone through to production.

The Bramaderos project comprises multiple porphyry gold-copper targets of which the Brama-Alba discovery is the most advanced with an expected inaugural Mineral Resource Estimate to be delivered in late 2022.

The El Palmar project is the subject of a Staged Acquisition Agreement with Ecuadorian company Golden Exploration Ecuador (‘GOEX’). Sunstone owns 70% of GOEX and can acquire 100%. Sunstone discovered significant gold-copper mineralisation at El Palmar in late 2021 and is continuing to drill and expand the discovery.

The team at Sunstone has a track record of discovery having been involved in significant discoveries of porphyry and epithermal copper-gold mineralisation at Tujuh Bukit in Indonesia and Cascabel in Ecuador and is preparing to repeat that success at Bramaderos and El Palmar.
