PERTH(BullionStreet): Middle Island Resources (ASX:MDI) has returned high gold recoveries from its K4/K5 gold prospect within the Reo project in Burkina Faso.
Average gold recoveries of 93%, 97% and 95% were returned from oxide, transitional and primary ore types respectively at the prospect.
A suite of 17 individual diamond core samples, representative of all oxidation states, rock types, gold grades and alteration styles, was subjected to preliminary cyanidation testwork.
These test results showing high indicative gold recoveries confirm that the K4/K5 ore is likely to prove amenable to conventional carbon-in-leach (CIL) and possibly even heap leach recovery.
Significant new intercepts include 63m at 1.25 grams per tonne gold, 16m @ 2.66gpt gold, including 12m at 3.23gpt gold, 20m at 1.65gpt gold, including 8m at 3.17gpt gold, 8m at 4.68gpt gold, including 4m at 8.21gpt gold, 8m at 1.7gpt gold, 4m at 2.25gpt gold and 6m at 1.24gpt gold.
It provides considerable confidence before Middle Island starts on a resource definition drilling.
Middle Island’s Managing Director, Rick Yeates, said that “it has been a transformational few weeks at Middle Island, firstly with identification of a significant ‘stand-alone’ resource target at the flagship K4/K5 Prospect, followed by these encouraging preliminary cyanidation test results."
“While RC (reverse circulation) pattern drilling will provide the ‘proof in the pudding’, these were two key boxes that required ticking in the Company’s progress towards a significant rerating," Yeates said.
