The explorer’s 22,000-metre RC program is designed to support a material expansion of the Kalgoorlie project’s existing mineral resource inventory.
Nexus’s managing director, Andy Tudor, says the program will focus on three priority prospects: Clement, Payns, and Branches.
“The company has applied a disciplined exploration approach over the past 18 months, resulting in a pipeline of high-quality prospects advancing to definition stage. This RC program is a key step in progressing Wallbrook from systematic exploration success toward meaningful resource growth,” Mr Tudor said.
“The program will build on early success at Clement, Payns and Branches prospects, while also testing lateral extensions to the established Crusader–Templar resource.
“The program plans to progress exploration success into high-quality gold ounces for the Wallbrook mineral resource inventory, with a multi-prospect mineral resource estimate planned for later in 2026.
The Clement, Payns, and Branches prospects at Wallbrook have been discovered and developed through a systematic 18-month exploration effort comprising multiple aircore drilling programs and preliminary RC drilling.
Mr Tudor said the prospects have demonstrated the scale, continuity and grade profile required to support resource definition drilling.
Discoveries at Godfrey and Amand prospects also remain highly prospective targets and will be assessed in Nexus’s future RC programs. In parallel, recent optimisation work at the Crusader-Templar deposit has identified lateral extension opportunities, which will be tested as part of the current campaign.
Crusader-Templar currently hosts the only combined mineral resource estimate (MRE) at Wallbrook of 1.7 million tonnes (Mt) at 1.7 grams per tonne (g/t) for 304,000 ounces, providing a strong foundation and clear opportunity for resource growth as part of the current drilling campaign.
Initial assays are anticipated in May CY26; subsequent results will release progressively.
