Regis Resources is advancing exploration across its Australian gold operations, with new drilling results and resource definition programs strengthening its pipeline of potential mine-life extensions and future mining areas.
The company’s latest exploration update highlights progress at several deposits within its Duketon operations in Western Australia, alongside drilling at Tropicana and early-stage prospects near McPhillamys in New South Wales.
At Beamish South, Regis has completed resource definition drilling ahead of an updated mineral resource estimate, while new intersections at Garden Well and Moolart Well have identified further opportunities around established mining infrastructure.
Regis Resources managing director and chief executive officer (CEO) Jim Beyer said the results reinforced the company’s strategy of pursuing growth opportunities across its existing portfolio.
“Our exploration teams delivered another period of solid progress. At Rosemont, drilling confirmed that the mineralised host unit extends a further 600m south of the stage 3 resource and remains open,” he said.
“While at Garden Well, deeper surface drilling is building on the early indications of a down-plunge extension.
“Our first diamond holes below the Moolart Well open pits intersected fresh-rock gold mineralisation below a deposit that was mined largely in the regolith.
“These are early results with most assays outstanding, but they open an exciting new exploration opportunity at Duketon North, close to the Moolart Well mill.”
At Beamish South, drilling returned 14.3m at 4.6 grams per tonne (g/t) gold from 304m, including 1m at 54.2 g/t gold, as Regis completed its resource definition program for a proposed open-pit.
The deposit has an initial mineral resource of 7 million tonnes at 1.1 g/t gold, equating to 270,000 ounces, announced in June. Regis is preparing an updated resource estimate to assess whether Beamish South could support an initial ore reserve, with optimisation work to follow the receipt of outstanding assay results.
At Garden Well South, diamond drilling confirmed mineralisation approximately 200m beyond the existing reserve boundary, returning intersections of 6.2m at 1.9 g/t gold from 621m and 5.1m at 1.7 g/t gold from 640.9m.
Further north, drilling beneath the Moolart Well open pits identified fresh-rock gold mineralisation, including 16.6m at 2 g/t gold from 342m at Moolart Central and 1.7m at 7.8 g/t gold from 536.4m at Moolart Well.
Regis said the results represent an early-stage exploration opportunity beneath deposits previously mined predominantly for near-surface gold, although further interpretation is required to establish their significance.
At Tropicana, drilling comprised 105 holes for 41,599m, targeting the Swizzler, Havana and Havana South areas.
Results included 12m at 6.1 g/t gold from 436m at Havana South and 26m at 6.6 g/t from 145m at Havana. Drilling at Havana South is designed to improve confidence in existing Inferred resources and support studies assessing the economic viability of a potential additional underground mining area.
Regis also reported further exploration results at Kings Plains and Last Chance near McPhillamys in New South Wales, where drilling confirmed gold mineralisation along strike and beneath historic underground workings.
The company is assessing nearly 100 exploration prospects and projects across its portfolio, with programs ranging from early-stage exploration to resource definition and potential reserve development.
“These results continue to validate our disciplined, geology-led approach to exploration and reinforce confidence in our potential to continue growing our Mineral Resources and extend mine life across the business,” Beyer said.
