THE DRILL SERGEANT: Sunstone Metals (ASX: STM) received encouraging initial results from a surface trenching program at the Limon prospect, part of the company’s Bramaderos gold-copper project in Ecuador.
Sunstone Metals said the first batch of assays from the initial trench (LM-01) at Limon from trench LM-01 intersected 35.9 metres at 0.92 grams per tonne gold and 0.4 per cent copper, with the intersection at surface remaining open on all sides.
Peak copper and gold assays were 1.94m at 1.2g/t gold and 1.25 per cent copper and 2.06m at 1.74g/t gold and 0.41 per cent copper from separate samples.
The company explained that geological mapping, alteration mapping using spectral analysis, as well as soil and rock geochemistry all support its interpretation of the results of an outcropping window of a more extensive mineralised diorite body.
Sunstone said the results indicate that there are multiple targets for porphyry gold-copper mineralisation at the extensive Limon prospect.
“These initial trench results from Limon are extremely encouraging,” Sunstone Metals managing director Malcolm Norris said in the company’s announcement to the Australian Securities Exchange.
“This is a breakthrough result for our Bramaderos project, where we have now identified higher grade porphyry mineralisation at surface within a very large area of altered rock.
“Limon will be amongst the first areas to be drill tested, together with Bramaderos Main and West Zone targets.”
