Kin Mining NL (ASX:KIN) (FRA:8KM) has unveiled positive results from water supply and infrastructure test work at its Cardinia Gold Project (CGP) in WA after reporting encouraging drilling results yesterday.
The company said work programs were progressing well on several fronts, with its water bore drilling and test pumping showing adequate water supplies.
Cardinia project’s Bummer Creek bores tested to combined 35 to 40 litres a second while the Cardinia Creek bores flowed at 25-30 litres a second.
The company believes this supports a steady-state water use requirement of 50 litres a second and peak demand of 70 litres a second.
Sterilisation drilling at Lewis Waste Dump and Tailings Storage Facility and Helens Waste Dump is complete, with assaying in progress.
Metallurgical test work in fresh rock showed good recovery during Kin’s efforts.
A gravity recovery of 17-20% gold was achieved on Master composites.
Kin did well with coarse grinds, telling the market today: “Coarse grind appears optimal which has positive implications for future operating costs compared to previous estimates.”
The Lewis prospect had 92.8% total recovery at 150um grind while Helens prospect had 85.4% total recovery at a 106um grind.
Cyanide and lime consumption was low.
Variability testing will continue to optimise grind size, with the company reporting it was on track to complete the test work program in the June quarter.
A sulphide, mostly pyrite concentrate (LHS), from Lewis Fresh ores.
Gold recovery for Lewis Master composite samples is about 0.41 g/t gold or 20%.
Kin yesterday unveiled returned results from drilling at Lewis and Helens prospects.
An updated resource is also expected in the June quarter.
At Lewis, eight diamond holes were drilled for 1,242 metres and 1,472 additional metres of reverse circulation (RC) drilling.
Seven of the eight diamond holes have been returned, with one still to come back from the laboratory.
Best results from the seven diamond holes were:
Results from the Lewis RC holes are still to come.
At Helens, 14 diamond holes were drilled for 1,085 metres while RC drilling took in 837 metres.
Assays have been received from nine of the diamond holes with best results being:
The company’s ongoing drilling program is now moving to Cardinia’s Mertondale 5 and Bruno prospects.
