Great Boulder Resources unearths new gold targets across Side Well Project in WA

Great Boulder Resources (ASX:GBR) has uncovered new gold targets following an infill auger sampling program at its Side Well Gold Project in Western Australia. 

The results, generated by auger samples gathered from over 5km of strike north of the Ironbark prospect have defined a +4km target with anomalous gold and pathfinder elements. 

Great Boulder notes sampling has confirmed 2 multi-point gold anomalies north of Ironbark within the same mafic-ultramafic sequence as the Ironbark discovery. This target is also supported by a similar pathfinder association as Mulga Bill, as well as a ‘large’ high-tenor bismuth and arsenic anomaly and broad zones of elevated copper. 

The company says rock chip sampling results returned from Saltbush (Ironbark South) have delivered gold (Au) grades up to 14.85g/t Au near a historic reverse circulation (RC) intersection of 3m @ 7.42g/t Au from 14m. 

Drilling is currently ongoing at the Mulga Bill prospect with first results expected to be received in March.   

Speaking on the results, Great Boulder Managing Director Andrew Paterson says: “Infill auger sampling north of Ironbark has confirmed a large high-priority exploration target within the same mafic-ultramafic sequence as the Ironbark discovery. This anomaly is a broad zone of strong bismuth and arsenic anomalism which contains two discrete gold targets.

The target is approximately 4km long and almost 2km wide, with broad zonation from bismuth-copper-molbdenum in the east grading towards arsenic and silver in the west. This represents a temperature gradient from hotter elements on the granite contact and cooler elements dropping out further west of the granite.

“This anomaly is a broad zone of strong bismuth and arsenic anomalism which contains two discrete gold targets”

The auger and AC results returned along the eastern stratigraphy at Side Well has now defined a hydrothermal gold camp spanning 15km of strike. 

During this program we also took more rock chip samples from historic workings at the Saltbush prospect at Ironbark South which confirm gold in quartz veins assaying up to 14.85g/t. Saltbush is a walk-up drill target and we will be testing that area as soon as we have heritage clearances in place.

With our maiden resource of 518,000oz at Mulga Bill and Ironbark and multiple large-scale, high priority drill targets we now have a clear pathway to deliver on the million-ounce potential at Side Well.”

Great Boulder also notes it will move forward with aircore (AC) drill testing on priority drill targets north and south of Ironbark following completion of Aboriginal heritage surveys. 

Great Boulder Resources is an ASX-listed mineral exploration company with a portfolio of highly prospective gold and base metals assets ranging from greenfields through to advanced exploration located in Western Australia. The company’s Side Well project is located near the township of Meekatharra in Western Australia’s Murchison gold field, and currently boasts an inferred Mineral Resource Estimate (MRE) of 518,000oz Au. 

Other assets included within Great Boulders exploration arsenal include the Wellington and Whiteheads projects in Western Australia.
