Great Boulder Resources (ASX: GBR) has extended the known strike of the Blue Poles prospect to over one km in length with the second phase of air- core (AC) drilling within the Whiteheads project north of Kalgoorlie.
This phase of drilling was designed to define the limits of mineralisation at Blue Poles prior to RC drilling, which is scheduled to be completed this month.
Blue Poles has now been closed off to the north but remains open to the south. The total strike length of the prospect is now in excess of 1km.
A single fence of AC holes drilled across a smaller geochemical target to the northwest also intersected anomalous mineralisation which will require additional testing in future programs.
Initial RC drilling is expected to begin at Blue Poles in the second half of November, slightly behind schedule due to a short delay in the contractor’s availability.
Notably, Great Boulder has made a VMS-style Pb-Zn discovery when a fence of holes drilled to the west to provide additional geological information intersected lead-zinc sulphide minerals at the bottom of a hole 500m west of Blue Poles. Assays include: 1m @ 13g/t Ag, 1.04% Pb and 1.01% Zn from 92m, and 2m @ 7.35g/t Ag, 0.63% Pb and 0.80% Zn from 97m to EOH.
Managing Director, Andrew Paterson, said this is a completely new discovery in an area with no surface geochemical signature.
The company will plan further work in order to assess the nature and scale of base metal mineralisation.
These new results add further weight to the Blue Poles discovery,” Mr Paterson said.
“We are very keen to get some deeper drilling into it with the RC rig shortly.
“The base metal discovery out to the west is completely unexpected, so we’ll also be working on that to see how significant it might be. There is no geophysics or historic drilling in the area, so it’s a true greenfields discovery.
“At this stage we are still receiving assays from the programmes completed at Side Well in September. We’ll have further updates on the Side Well air-core and auger programs in the coming weeks.”
