Kingston Resources Ltd (ASX:KSN) has delivered “exceptionally encouraging” gold recoveries averaging 93.8% during initial metallurgical test work at Livingstone Gold Project in the Bryah Basin region of Western Australia.
Gold recoveries averaged 89.5% in primary mineralisation, 95.6% in transitional mineralisation and 94.9% in the oxide mineralisation.
The company said that the results from the Accelerated Cyanide Leach were exceptionally encouraging, indicating that oxide, transitional and primary gold mineralisation at Kingsley prospect were amenable to conventional cyanide extraction methods.
“Outstanding result”
Kingston Resources managing director Andrew Corbett said: “Achieving average gold recoveries of 93.8% from preliminary metallurgical test work is an outstanding result.
“Kingsley has the trifecta of high grades in oxide, transitional and primary mineralisation, with this first-pass metallurgical test work indicating that each of these ore types is amenable to conventional cyanide extraction methods.”
Shares have been up almost 10% to an intra-day high of 2.3 cents after a new 12-month high of 2.6 cents was reached on September 24.
Samples from RC drilling
The test work was based on 16 ore samples collected from recent reverse circulation (RC) drilling at the Kingsley prospect.
Samples were selected from 10 RC holes across the prospect area, with intervals selected to provide varying grades, lithologies and weathering profiles.
The LeachWELL
Accelerated Cyanide Leach test provides an indication of potential recoveries in metallurgical processes and circuits.
Livingstone Gold Project is 140 kilometres northwest of Meekatharra in the Bryah Basin region.
Mapping program
A regional structural mapping and interpretation program conducted by Dr Greg Cameron over the western portion of the Livingstone project area, including Kingsley and Livingstone North prospects, is nearing completion.
