Great Boulder records further ‘spectacular’ results including 3,160g/t Au at Mulga Bill in WA

Australian mineral exploration company Great Boulder Resources (ASX:GBR) has recorded further ‘spectacular’ results from drilling at the Mulga Bill prospect, located within the Side Well Gold Project in Western Australia.

The company reports fire assays from hole 23MBRC006A, drilled as part of phase one reverse circulation (RC) drilling at Mulga Bill, has confirmed ‘high-grade’ gold intersections.

Results recorded in 23MBRC006A include 7m @ 8.13g/t Au from 93m; 6m @ 589.44g/t Au from 114m, including 1m @ 3,160g/t Au from 114m, and 1m @ 366g/t Au from 115m; as well as 6m @ 396.58g/t Au from 154m, including 1m @ 2,250g/t Au from 158m, and 1m @ 94.40g/t Au from 159m.

Great Boulder is currently finalising timing for an initial Aboriginal heritage survey at the Wellington project, located 500km east of Side Well in the Earaheedy Basin. This heritage survey is expected to be followed by a wide-spaced soil geochemistry program.

The company was originally planning to conduct heritage monitoring and soil sampling concurrently, however these activities will now be completed separately. Once geochemical data from the soil sampling program has been received and assessed, Great Boulder will confirm the next steps for Wellington, including the option of an aerial Falcon gravity survey.

Great Boulder’s share price had risen 10.344% as of 8.45am AWST on the back of the announcement.

Commenting on the results, Great Boulder Resources Managing Director Andrew Paterson says: “These are extremely high-grade results, and while the spectacular visible gold intersections in 23MBRC006A have garnered plenty of attention it’s great to see the new deep high-grade zone in hole 23MBRC008.

The Challenge Drilling RC rig will be back on site in the second week of April for a follow-up program at Mulga Bill and Ironbark. By that time, we will also have results coming through from the AC (aircore) drill program within the 6km Mulga Bill corridor.”

The company reports the 2023 phase one RC program at Mulga Bill comprised 13 holes for 3,393m testing positions within the Central and HGV zones. Samples from the 2 intersections of visible gold in 23MBRC006A were initially assayed using the Chrysos Photon assay technique and were subsequently re-assayed using a standard fire assay technique.

Other results recorded at Mulga Bill include 23MBRC008 with 4m @ 22.10g/t Au from 184m, and 19m @ 12.83g/t Au from 229m, including 2m @ 112.40g/t Au; 23MBRC002 with 4m @ 7.24g/t Au from 108m; and 23MBRC004 with 4m @ 5.30g/t Au from 218m.

Assay results for 3 RC holes from phase one drilling are currently pending.

The company says the current aircore (AC) drilling campaign is expected to finish in about 2 weeks, which will be followed by follow-up RC drilling at Mulga Bill and Ironbark in the second week of April.

Great Boulder Resources is an Australian mineral exploration company with a portfolio of ‘highly’ prospective gold and base metal assets ranging from greenfields through to advanced exploration in Western Australia.

The company’s core focus is the Side Well Gold Project near Meekatharra which hosts an inferred resource of 6.192 million tonnes @ 2.6g/t Au for 518,000 ounces. It also holds the Wellington Base Metal Project in the MVT province.
