Western Australian gold explorer Kin Mining (ASX: KIN) has expanded and strengthened the high-grade gold potential of its Cardinia Hill deposit with new drilling results from its ongoing resource definition program.
The company today posted “outstanding” new wide, high-grade gold intercepts including 7m at 21.3 grams per tonne gold from 91m in the sulphide zone and 8m at 4.02g/t gold from 19m in the oxide zone.
These latest results build on the initial batch of high-grade gold assays reported from the drilling program in late March.
Kin managing director Andrew Munckton said each batch of results has further extended the mineralisation at Cardinia Hill both close to surface and at depth.
“We are particularly pleased to see some outstanding high grades coming through in these latest results from areas outside the initial mineral resource estimate boundary, which is consistent with our strategy of targeting high-grade additions at depth and along strike to increase the value of the deposit and extend the mineral resource estimate into other open pit and potential underground mining positions.”
“These results will all feed into what we hope to be a significant mineral resource upgrade at Cardinia Hill, which will cement its position as one of our cornerstone deposits at the Cardinia gold project,” he added.
The company kicked off the 58-hole, 9,100m reverse circulation (RC) and diamond drilling program at the deposit in February. The program is now about 60% complete, with 34 holes reported to date including 14 new holes announced today.
Another 13 holes have been drilled with assays awaited, including six deep diamond core holes, and a further 15 holes are yet to be drilled.
Extending Cardinia Hill’s resource
The Cardinia Hill prospect was discovered in early 2020 about 2km from the proposed processing plant site at Kin’s 100% owned Cardinia gold project near Leonora, WA.
An initial shallow RC and diamond drilling program had defined an inferred mineral resource totalling 1.2 million tonnes at 1.66 grams per tonne for 61,000 ounces of gold in December.
Today’s results from the ongoing resource definition drilling program have confirmed the continuity of mineralisation and elevated gold grades with drilling extending both the shallower and deeper high-grade mineralisation of the deposit along the Cardinia Hill fault to the north.
Other significant new assays include a deep intercept of 3.4m at 9.72g/t gold from 252.6m and 5m at 4.99g/t gold from a shallower 21m.
Following completion of the resource definition program, metallurgical test work will be completed to obtain samples and confirm the metallurgical and treatment performance of the Cardinia Hill deposit.
Bruno Lewis and other drilling
Meanwhile, Kin reported further strong assay results from a recent RC and diamond extension drilling campaign at the Bruno Lewis deposit including 16m at 1.22g/t gold from 51m and 7m at 7.67g/t gold from 83m.
Kin said the mineral resource estimate update for the deposit is “well underway” with final delivery of the model expected “in the coming week”. The estimate will then be released once the final model has been checked, accepted and optimised.
In addition, a large portion of the Eastern Corridor RC drilling program has been completed which is testing a series of targets along the fault on which the Cardinia Hill deposit sits.
“The geological team is eagerly awaiting the assay results from this program,” Mr Munckton said.
Drilling continues with three rigs currently operating at the Eastern Corridor, Eagle and Cardinia Hill prospects across the project.
