Great Boulder Resources (GBR) has extended the mineralisation at the Blue Poles discovery to more than one kilometre in length.

Blue Poles lies within the Whiteheads project which is located 60 kilometres north of Kalgoorlie in Western Australia.

Great Boulder has completed its second phase of drilling which aimed to define the mineralisation at Blue Poles before reverse circulation (RC) drilling begins.

Due to a slight delay in the contractor’s availability, RC drilling is scheduled to begin in late November.

All up, 51 holes, for 2476 metres, were drilled at Blue Poles, with aims to also test discrete gold-in-soil anomalies.

New results include one metre at 13g/t silver, 1.04 per cent lead and 1.01 per cent zinc from 92 metres, and 12 metres at 0.83g/t gold from 28 metres, including four metres at 1.21g/t gold.

Blue Poles has now been closed to the north but remains open to the south and spans a length of more than one kilometre.

“These new results add further weight to the Blue Poles discovery. We are very keen to get some deeper drilling into it with the RC rig shortly,” Managing Director Andrew Paterson said.

Great Boulder has also announced that it has entered a sponsorship agreement with Portable ppb (PPPB).

This agreement will allow GBR to access PPPB’s detectORE technology in its field exploration programs.

detectORE is a patented technology which allows handheld portable x-ray fluorescent (pXRF) guns to detect gold values less than 10 parts per billion (ppb) in near realtime samples.

This speeds up the assay time which currently takes up to weeks via laboratory analysis or overnight in the field.

This will be a gamechanger for gold analysis, as current pXRF technology cannot detect gold in concentrations of less than 1000ppb (1.0g/t).

“This sponsorship is very much in line with GBR’s philosophy of using new technologies to explore more efficiently wherever possible,” Andrew said.

“This will be a step-change in our early-stage exploration, particularly in areas like Side Well where we have big areas of unexplored terrain to cover,” he added.

Great Boulder is up 2.13 per cent on the market with shares trading for 4.8 cents each at 12:04 pm AEDT.
