New high-grade lodes are a shot in the arm for Kingwest’s gold ambitions

Special Report: Kingwest’s belief that its historic Menzies project (MGP) hosts more high-grade gold has been bolstered by recent drilling that intersected new high-grade lodes.
The new lodes were intersected by first pass drilling within the Central Zone as part of the diamond core and reverse circulation drilling completed during the first half of 2020.
Kingwest Resources (ASX:KWR) said drilling also returned high-grade intercepts that extended known mineralisation at the Stirling prospect and Yunndaga Deeps.
Notable results are 3m at 6.66 grams per tonne (g/t) gold from a depth of 24m, 2m at 11.27g/t gold from 51m and 6m at 3.41g/t gold from 142m.
Results above 5g/t are generally considered to be high-grade.
“We are very pleased that first pass drilling within the Central Zone has discovered numerous new gold lodes that add to our known deposits,” chief executive Ed Turner said.
“Drilling at other targets has also resulted in extending significant high-grade mineralisation at Stirling and Yunndaga.”
Turner said the intersection of significant mineralisation in the majority of holes drilled to date made Kingwest increasingly confident that the MGP could again be a long-term high-grade gold producing province.
“Optimisation studies are now underway in order to advance the known mineral resources towards production,” he said.
Kingwest plans to carry out infill drilling to upgrade the levels of confidence from the inferred to indicated or measured categories which will in turn lead to scoping studies in the second half of 2020.
The historic MGP in the Eastern Goldfields of WA consisted of five underground mines that produced a total of 650,000 ounces of gold at an average grade of 22.5g/t gold between 1895 and 1943.
A further 145,000 ounces at an average grade of 2.6g/t gold was produced from open cut mining between 1995 and 1999.
Despite this, modern exploration has been limited since mining ceased over two decades ago.
However, Kingwest’s earlier 25g/t intercept 731.47m from surface, or about 60m below the deepest workings at the Yunndaga mine, has highlighted the high-grade and open-ended nature of the old deposits.
Menzies currently has a resource of 3.67 million tonnes grading 1.97g/t gold for 233,300 ounces of contained gold.
