Nexus Minerals Ltd (ASX:NXM) has started extensional reverse circulation (RC) drill programs at its Crusader-Templar and Branches prospects, part of the wider Wallbrook Gold Project, 140 kilometres northeast of Kalgoorlie in Western Australia.
The company will conduct an extensional ~3,000-metre drill program at Crusader-Templar and a ~4,400-metre RC drill program at Branches when it is finished at Crusader.
Further to this, Nexus is undertaking regional exploration aircore drilling at two prospects MC4.1 and MC3.1, within the Wallbrook Project.
In October it began chasing down several high-priority drill targets through a regional aircore program set to drill 10,000 metres at MC4.2 and MC3.1.
8,429 metres of the 355-hole aircore drill program is now complete.
Extensional drilling "warranted"
“The resource modelling work at Crusader-Templar has shown that extensional RC drilling is warranted to extend the areas of known mineralisation,” Nexus managing director Andy Tudor said.
“The same has been the case at Branches where extensional RC drilling is warranted to add to the existing drill footprint.
"The aircore drill program testing the first two regional targets MC4.1 and MC3.1 has just completed and the company geologists have been very encouraged by the rocks intersected.”

Successful drilling
Nexus has had success using aircore drilling across the wider tenement package, most notably in the 2021 discovery of its Templar Prospect.
Considering this, two targets suitable for air-core drilling and prospective for gold mineralisation have been subject to first-pass drill testing, with 8,429 metres/355 holes drilled at Target (NYSE:TGT) 4.1 and Target 3.1.
Quartz-goethite alteration and hematite-altered quartz porphyry was intersected in several of the drill holes. This is the same mineralisation style as that seen at the Crusader-Templar and Branches prospects.
The “right rocks” were intersected at both target areas, exhibiting the potential to host gold mineralisation.
