Ottawa - Cornerstone Capital Resources Inc. ('Cornerstone' or 'the Company') is pleased to provide 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 Inc. (ASX: STM) through to the start of commercial production.

HIGHLIGHTS

Two latest holes (ESDD008 and ESDD009) at Espiritu extend the known strike length of the silver-gold mineralization to 700m

Drill hole ESDD009 intersected 2 significant lodes of silver-gold-zinc-lead mineralization including: 2.5m at 65.9g/t silver, 1.63g/t gold from 369.5m

0.5m at 141g/t silver, 0.28g/t gold, 0.52% copper, 2.73% lead and 1.15% zinc from 370m

0.6m at 154g/t silver, 6.46g/t gold from 371.4m (only 140m below surface)

Detailed soil geochemistry has defined several significant anomalous areas to the south-east for drilling

Espiritu is one of several similar targets within the Bramaderos project area

Cornerstone VP Exploration, Yvan Crepeau, said: 'These results provide more evidence that Espiritu is a large silver-gold system. It is still early days in the exploration of this system, and we are still developing models for the style and geometry of mineralization, that will in turn enable us to better target the higher-grade areas.

'The early benefits of this approach are seen in drill hole ESDD009, which delivered the highest gold grades we have seen in the system.

'Once ESDD011 is completed we will review all data to plan the next phase of drilling. This will include drilling at Espiritu Southeast where Espiritu style veining is present at surface and corresponds with a cluster of silver-in-soil anomalies over a strike length of 400m. Espiritu is just one of several similar targets within the Bramaderos Project area, which require further exploration.'
