Sunstone Metals (STM) has highlighted the potential of higher-grade mineralisation at the Brama target in Ecuador.
In light of this Sunstone now believes it has several higher-grade drill targets within a very large but lower-grade gold-copper porphyry system.
The Bramaderos Project, where Brama is located, is situated 460 kilometres south-southwest of Ecuador’s capital city, Quito and covers an area of 4949 hectares.
Bramaderos was explored infrequently from 1970 to 1984, 2001 to 2002, and 2004 to 2007.
Gold mineralisation was first identified in 1970 during regional stream sediment surveys, and anomalous copper, lead, zinc and molybdenum was identified in streams and soils in the area.
The project is considered highly prospective for the discovery of large porphyry gold-copper systems and high-grade epithermal gold systems.
Historical exploration results coupled with recent exploration results, indicate multiple fertile mineralised systems with significant discovery potential.
Assays from the recently completed hole BMDD007 identify mineralised intervals that correlate with relatively more magnetic bodies.
Detailed analysis of the 3D magnetic model identifies clusters of these more magnetic bodies at Brama and at five other porphyry targets within Bramaderos.
These targets include Limon, Playas, Melonal, Porotillo and Sandia.
Highlights from the hole include 40.6 metres at 0.49g/t gold and 0.11 per cent copper from 170.6 metres, and 51.8 metres at 0.47g/t gold and 0.11 per cent copper from 55.7 metres.
“We have clearly demonstrated a very large gold-copper mineralised body at the Brama target,” Managing Director Malcolm Norris commented.
“The development of this model at Brama will also apply to our five other large porphyry targets within the Bramaderos Project,” he added.
Sunstone’s share price has slumped 16.7 per cent on the market today and shares are trading for 1 cent apiece at 3:51 pm AEDT.
