(Alliance News) - Great Southern Copper PLC on Monday announced "exceptional" high-grade copper-gold results at the Mostaza Deposit at its Cerro Negro mine in Argentina.
The Chile-focused copper, gold and lithium explorer said results showed assay grades consistently significantly higher than those of historical drill programs.
Highlighted results at the included 12.0 metres of 4.3% copper and 369.5 grams per tonne of gold from 40 metres.
Drilling also showed 13.0 metres of 2.5% copper and 198.1 grams per tonne of gold from 39 metres; and 4.2 metres of 1.7% copper and 126.5 grams from 38.9 metres.
Chief Executive Officer Sam Garrett commented: "These outstanding results confirm that high grade Copper-Gold mineralisation is continuing to depth and along strike and demonstrate that the former Mostaza mine has the potential to be a high-grade high-value Copper-Gold deposit."
GSC holds an option to own 100% of the Mostaza mine and Cerro Negro project.
CEO Garrett added that two diamond drill rigs are now on site, with one targeting strike and depth extensions of the Mostaza pit mineralisation and a second rig exploring a structural trend to the south.
Moving, forward, Great Southern says phase II drilling at Mostaza has begun and will include resource and exploration drilling. Metallurgical studies of drill core, stockpiles and tailings are also being planned. Extensions of mineralisation at depth and along trend under cover may be targeted with geophysical surveys.
"We have entered a very exciting phase of exploration at Cerro Negro and have a lot of work to do as we progress to demonstrate the potential economic viability of this exciting deposit," said CEO Garrett.
Great Southern Copper traded 8.2% higher at 3.57 pence on Monday afternoon in London.
