Exploration continues apace across the country this week, with Kingston, True North and Cauldron all reporting strong results.
Kingston ramps up Mineral Hill drilling campaign
Kingston Resources has kicked off a new phase of surface and underground drilling at its 100 per cent-owned Mineral Hill mine, with two rigs now onsite to drive resource growth and near-mine discovery.
The underground program is targeting high-grade extensions within the Southern Ore Zone, aiming to upgrade inferred resources and firm up future mining opportunities. The surface campaign will focus on discovery potential across exploration licences EL1999 and EL8334, beginning with drilling at the Bogong and Long Panel prospects.
Kingston reported high-grade copper assays from Long Panel rock-chip sampling. An induced polarisation (IP) survey was also completed over the area ahead of drilling to refine target definition.
The company said the renewed drilling push represents a strategic investment in expanding Mineral Hill’s resource base and building future optionality.
“The arrival of two drill rigs marks the commencement of a targeted investment in resource definition and discovery drilling, supporting Kingston’s growth strategy,” the company said.
Aquila discovery pushes past 900m strike as Mt Oxide expands
True North Copper’s Aquila discovery at the Mt Oxide project continues to build scale, with the mineralised strike now extending more than 900 metres and multiple high-grade shoots confirmed through ongoing Phase 2 drilling.
Assays have been returned for four of eight outstanding drillholes, highlighting two steeply plunging high-grade shoots: a northern shoot about 250m long and a southern shoot about 150m long.
Both remain open at depth, with holes MOX260 and MOX259 supporting the continuity of the southern shoot within a broader mineralised zone.
Initial southern drilling – completed despite suboptimal collar locations – has also confirmed the system extends further south and has provided improved positions for follow-up drilling planned for 2026.
The growing footprint places Aquila on par with True North’s existing Vero deposit, which hosts a 1,000m strike and a 15.03Mt resource at 1.46 per cent copper.
True North managing director and CEO Andrew Mooney said: “It’s becoming increasingly clear that we’re onto something big here at Aquila, with the potential to exceed the scale and quality of our existing high-grade Vero Resource at Mt Oxide.”
High-grade uranium at Manyingee North
Cauldron Energy has intersected thick, high-grade uranium mineralisation in the first drillholes completed at its Manyingee North prospect, marking a significant new discovery within the Yanrey uranium project in Western Australia.
Assays from the first five holes (25YRAC034–038) returned multiple high-grade intervals, including standout results from hole 25YRAC038, which delivered 2.72m at 887.2ppm eU₃O₈ from 96.92m. Other strong intersections included 2.20m at 471.4ppm eU₃O₈ and 3.00m at 320ppm eU₃O₈ in hole 25YRAC037, along with several additional zones above the company’s 150ppm cutoff.
All five holes intersected broad mineralised zones beginning at depths of around 90m and extending towards bedrock. Cauldron said the mineralisation spans more than 600m across the initial drill line and a further 250m to the south, with the system remaining open in every direction.
The uranium is hosted within a largely untested northeast-trending extension of the Manyingee palaeochannel, located about 2.5km northeast of Paladin Energy’s Manyingee deposit.
Cauldron said the results confirm the potential for a substantial new zone of uranium mineralisation at Yanrey, with follow-up drilling planned to define scale and continuity.
