THE DRILL SERGEANT: Great Boulder Resources (ASX: GBR) reported remaing assay results from reverse circulation (RC) drilling undertaken at the company’s Side Well gold project near Meekatharra in Western Australia.
The full RC program consisted of twelve RC holes targeting strike extensions to mineralisation intersected in previous drilling.
The company said the RC results support its interpretation of a north-easterly trend to mineralisation, with intersections including:
16 metres at 1.7 grams per tonne gold from 76m, including 4m at 3.62g/t gold from 80m downhole, and 1m at 7.35g/t gold from 142m downhole;
8m at 1.15g/t gold from 130m downhole and 3m at 1.16g/t gold from 153m downhole; and
12m at 1.59g/t gold from 92m downhole.
The later results were achieved approximately 400m southwest of the high-grade 7m at 3.35g/t gold from 122m intersection previously reported in hole 20MBRC004.
Great Boulder has also received initial assays from recently commenced AC drilling at the northern end of the Mulga Bill trend, with encouraging early results including:
4m at 2.13g/t gold from 76m; and
12m at 1.1g/t gold from 52m.
The company considers the initial results suggest Mulga Bill sits within a large mineralised system, with gold identified over more than three kilometres of strike and coincident with a deeper weathering profile and extensive shearing.
“These initial RC holes have given us a lot of information on Mulga Bill, particularly the rock types and alteration associated with the gold,” Great Boulder Resources managing director Andrew Paterson said in the company’s announcement to the Australian Securities Exchange.
“Our air-core program covered more than 3km of strike which will be a valuable targeting tool for ongoing work.
“The southern-most line is 650 metres further south than any previous exploration drilling.
“The depth of weathering and variable shearing we’ve logged in the main corridor of Mulga Bill indicate this is a big system.
“We believe further drilling will be the key to unlocking its full potential.”
