Multi-mineral explorer Solstice Minerals Ltd (ASX:SLS) has picked up grades of up to 25 percent copper from samples taken during an extensive phase of fieldwork and historical analysis of its Yarri project in Western Australia.

The rock chip samples were taken from Prospect A- one of two historical copper prospects at the Cosmo Exploration Licence connected to Yarri – and included results of up to 25 percent copper, 6.12 grams per tonne gold and 136.75 grams per tonne silver.

Prospect A had previously been the site of shallow trenching, yielding rock chip samples of up to 17 percent copper, and this historical evidence had prompted Solstice to conduct fieldwork there in April to pinpoint the prospect area and collect modern samples for analysis.

Meanwhile, at Prospect B, Solstice identified a coherent copper anomalism over 1 kilometre of strike from UltraFine faction soil sampling. This area had also been the site of historical trenching for base metals, and is currently surrounded by shallow soil cover.

The copper anomaly found at Prospect B peaked at 423 parts per million (ppm) over the 1 kilometre of strike, with this being the strongest UFF result for the metal at Yarri.

Solstice Minerals’ CEO and managing director Nick Castleden said the relatively untouched nature of the territory in modern times meant that there was plenty of opportunity to find impressive results there.

“We are pleased to have identified promising copper-gold-silver indicators at Cosmo, particularly as the area appears to be untested by drilling and has not seen modern geophysical techniques,” he said.

“The Yarri Project has a geological setting prospective for copper-gold VMS styles and there are a number of other historical copper and base metal anomalies in the Yarri dataset that may warrant follow up with present day methods.

“The team will carry out further field work and consider best ground geophysical tools to
bring forward drill targets for testing in the near future.”

Yarri is located in WA’s Eastern Goldfields region, and the Cosmo Licence being 130 kilometres northeast of Kalgoorlie and 6 kilometres northwest of Northern Star Resources’ Porphyry mine.

Solstice has been trading at 16.2 cents.
