Mamba is carrying out auger drilling to test a number of large regional structures at its Ashburton project in Western Australia’s Gascoyne Mining District.

These structures – including Lyndon and Osbourne Well – are interpreted to control gold mineralisation at the project.

Mamba Exploration (ASX:M24) expects the 3,500 hole program to take about a month to complete with first assays anticipated about six weeks from submission.

“The strategy has always been to actively explore the Kimberley and Ashburton projects during the winter months and the Darling Range and Great Southern project during the summer months,” managing director Mike Dunbar said.

“It is pleasing that we have been able to secure an auger rig to allow the Ashburton drilling to commence while we assess the targets highlighted from the recent geophysical reprocessing of data from our Kimberley projects.”

He added that once the weather allows, the company will recommence exploration on Darling Range and Great Southern with ground geophysics and drilling at the Black Hills target in the Darling Range and RC drilling and soil sampling in the Great Southern.

Auger drilling

Auger sampling at the Lyndon prospect will test the strike extent of historical workings where channel sampling of quartz veins returned results of up to 46.5 grams per tonne (g/t) gold while rock chips returned up to 81.2g/t gold.

This will also test some geophysical and structural targets within the tenement.

The 2,000 sample program also represents the first modern systematic sampling conducted over the tenement.

Over at Osbourne Well, the 1,500 sample program will test the interpreted regional structure that trends through the tenement.

Mamba believes this structure is the controlling feature for the Woods prospect mineralisation, where rock chip sampling by previous explorers identified up to 17.6g/t gold and 11.4g/t gold.
