General Mining hits high-grades at Chesterfield

/in /by

THE DRILL SERGEANT: General Mining Corporation (ASX: GMM) has received results from the first round of drilling at the company’s Chesterfield gold project, 50 kilometres north-west of Meekatharra in Western Australia.

The drilling has returned numerous high-grade intersections – up to 61 grams per tonne gold, which General Mining said demonstrates Chesterfield has potential to be a source of high-grade ore for several plants in the region.

This could take the form of a mine-gate sale or toll-treating campaigns, among other options.

Reverse Circulation (RC) drilling at Chesterfield gold project returned high-grade results at the Dorothy and Marguaritta prospects, including:

Dorothy

–    4 metres at 28.86 grams per tonne gold from 21 metres, including 2 metres at 53.89 grams per tonne gold;

–    5m at 5.46g/t gold from 38m, including 1m at 21.67g/t gold; and

–    4m at 33.81g/t gold from 33m, including 2m at 61.32g/t gold.

Marguaritta

–    5m at 2.73g/t gold from 13m; and

–    5m at 5.91g/t gold from 38m, including 2m at 12.29 g/t gold.

Drilling at the Dorothy prospect at Chesterfield targeted the mineralisation associated with the main workings.

General Mining said the drilling at Marguaritta confirmed mineralisation hosted by quartz veining within a foliated mafic volcanic or intrusive.

The company indicated the Dorothy structural position, just to the west of the Marguaritta mineralisation has not been adequately tested by historic drilling.

These targets and others identified by soil sampling have been tested sporadically over a strike length of 2km.
 
Marguaritta itself has been intersected over 950m from Marguaritta North to Marguaritta South and remains open to the north and south.

At Dorothy a number of diamond drill hole pre-collars have been completed as a precursor to diamond drilling due to commence in July.

General Mining said these holes will test the mineralisation beneath the weathered zone and provide information regarding the geometry, grade and nature of the primary mineralisation.

“The results support the company’s view that there is potential to outline a larger deposit by testing for extensions to the mineralisation over the two kilometre strike length between Dorothy and Marguaritta,” General Mining Corporation chairman Michael Wright said in the company’s announcement to the Australian Securities Exchange.

“These results show that Chesterfield contains high-grade gold and provide more evidence that there is significant scope to grow the known mineralization.

“The combination of the high-grade results to date, the potential to grow the known mineralisation along strike and at depth and the project’s close proximity to third-party processing plants give us every confidence in the economic outlook for Chesterfield.”
