Great Southern Copper PLC (LSE:GSCU) shares surged on Tuesday thanks to its latest high-grade copper and silver assay results from its Phase II drilling at the Mostaza Mine within the Cerro Negro prospect in Chile.
Chief executive Sam Garrett described the results as the project’s best to date.
In London, the share price climbed around 23% to change hands at 3.08p, and at one stage this morning reached as high as 3.2p.
Great Southern highlighted the best drilling results which included 6 metres at 6.61% copper and 542.4 grams per tonne silver (in hole CNG25 DD015).
This interval is part of a broader intercept of 9.9 metres at 5.47% copper and 442.5 grams per tonne silver from 41.15 metres. In hole DD016, the best result was 0.5 metres at 10.4% copper and 503 grams per tonne silver from 96 metres.
"These spectacular jewellery box copper and silver grades are our best results to date and continue to highlight the exciting potential of the Mostaza deposit at Cerro Negro," said chief executive Sam Garrett.
He added that planning for Phase III exploration drilling is well advanced and will be guided by recent geophysics and geochemistry data.
Great Southern Copper holds the option to acquire 100% of the Cerro Negro prospect, which is located at low elevation with good infrastructure access.
