Sunstone Metals (STM) has highlighted the potential for expanding the mineral resource estimate at its Bramaderos project in Ecuador through its latest drilling results.
The results revealed significant high-grade gold-silver mineralisation at Limon, extending from the surface to considerable depths.
Notable intersections included 42 metres at 3.9 grams per tonne (g/t) from 152 metres within and 243 metres at 1.32 g/t gold equivalent from 46 metres. Other significant hits are 15 metres at four g/t gold equivalent from 81.2 metres and 26 metres at 2.3 g/t gold equivalent.
These findings confirm the presence of structurally controlled high-grade gold-silver mineralisation within a larger zone of lower-grade mineralisation around it.
The Limon discovery is situated outside the current resource and exploration target at Bramaderos, suggesting significant upside potential for further exploration and development.
“Limon is now clearly a major shallow high-grade gold-silver discovery, which will underpin a significant increase in the scale, grade, and development prospects for Bramaderos.” STM Managing Director Malcolm Norris said.
The central high-grade zone extends from the surface to at least 300 metres deep and remains open in all directions along important geological structures.
Further exploration has reevaluated historical drilling at Limon, uncovering deep and narrow epithermal intersections overlying the outer porphyry halo.
These findings indicate the presence of an extensive epithermal system with substantial depth potential.
STM was down 7.14 per cent, trading at 2.6 cents at 3:06 pm AEST.
