Sunstone Metals has had a nice confidence boost at its Bramaderos project in southern Ecuador, with the latest assays from the Limon target extending the known gold-copper mineralisation – and highlighting the potential of the project to become a multi-deposit district.

The Limon target is 2.7km northeast of and sits outside the current Bramaderos gold-copper deposit, which hosts a porphyry mineral resource of 2.7Moz AuEq.

And these latest assays have strengthened the potential for a new gold-silver-base metal discovery from surface, with intersections including:

  • 87m at 0.41g/t AuEq (0.37g/t gold and 4.8g/t silver) from 40m (LMDD021), including 10.5m at 1.06g/t AuEq (0.99g/t gold and 8.5g/t silver) from 90.5m; and
  • 92m at 0.58g/t AuEq (0.52g/t gold and 7.4g/t silver) from 129.5m (LMDD022), including 13.3m at 1.2g/t AuEq (1.04g/t gold and 20.1g/t silver) from 153.7m.

Could be a 10Moz district with multiple deposits

“These latest results continue to expand the Limon epithermal gold-silver-base metal system beyond the initial discovery hole LMDD017 that intersected 176.7m at 1.1g/t AuEq* from 6.8m,” Sunstone Metals (ASX:STM) MD Malcolm Norris said.

“The drilling is delivering shallow and overall higher grades than the existing Bramaderos Mineral Resource estimate and Exploration Target.

“These results further underpin our plan to grow the resource base and assess development options which may include higher-grade starter pits and supports our view that Bramaderos has every potential to be a 10Moz district with multiple deposits within 4km of one another.

Plenty of upside potential

“We are seeing multiple sub-parallel zones of mineralisation at Limon which appear to have considerable vertical extent,” Norris said.

“There is plenty of upside to be delivered here with more drilling.

“Our broader Limon target gold in soil anomaly is 1.7km long by up to 700m wide, and together with multiple areas of zinc anomalism, a possible pathfinder, will be drill tested over the coming months.

“We are undertaking further metallurgical studies which are looking at both leach and float opportunities, and we are very encouraged by preliminary results”.
