Redstone Resources Maps Sampling at Rudall East and Cockatoo Rocks for Late 2026

Redstone Resources plans initial reconnaissance and sampling at its Rudall East and Cockatoo Rocks projects in Western Australia during the December 2026 and March 2027 quarters, the company said in a quarterly update covered by TradingView. The Perth-based explorer ended September with $391,000 in cash, down from $557,000 at the start of the quarter.

Redstone's Sampling Plans at Rudall East and Cockatoo Rocks

Redstone used the September quarter to rank targets across its recently acquired Western Australian portfolio and to assess site access. At Rudall East in the East Pilbara, desktop assessment and native title work are feeding proposed soil and rock-chip sampling over identified electromagnetic anomalies, with historical exploration intersecting sulphide mineralisation about seven kilometres east of the project. At Cockatoo Rocks, northeast of Kalgoorlie, the company is reviewing historical drilling and access obligations ahead of sampling for lithium-caesium-tantalum pegmatite targets. The work remains early-stage, and laboratory assays are needed to establish whether any pegmatites encountered contain lithium mineralisation.

Redstone holds program of work approvals for drilling at the Mt Cauden gold-lithium project near Southern Cross and the Twin Hills gold project in the Menzies district, though environmental requirements are still being assessed. Preliminary reconnaissance at Mt Cauden assessed accessibility, exposed geology, surface cover and potential sampling material, with drone-based three-dimensional photogrammetry used where ground traverses were impractical. The Mt Cauden approvals also cover an optional aircore program to investigate geology beneath cover on the project's eastern side.

Redstone's West Musgrave Program and Tollu Resource

Redstone is a pre-revenue mineral explorer whose flagship asset is the 100%-owned Tollu copper project in Western Australia's West Musgrave region, according to akta.pro company records. A maiden JORC-compliant mineral resource at Tollu was estimated at 3.8Mt at 1.0% copper, or 38,000 tonnes of contained copper, including 8,000 tonnes of contained copper in an oxide resource. A conceptual exploration target across 24 prospects was stated at 31 to 47 million tonnes at 0.8-1.3% copper, containing 259,000 to 626,000 tonnes of copper.

At West Musgrave, a proposed 3,300-metre reverse circulation program has shifted to the March 2027 quarter. The campaign will test magnetic targets northeast of the Tollu copper deposit, including EM5, East and West Cigar, and Hiding Maggie. An Exploration Incentive Scheme co-funded drilling grant could contribute up to $230,000 towards that program. Redstone is separately reviewing historical data and native title requirements at the 330km² Saturn project.

Yukon Metals and Harvest Gold Advance Projects

Peer explorers also advanced projects in late October. Yukon Metals is advancing its AZ Copper-Gold project in Yukon, which spans nearly 20 km, after confirming a new copper-gold-molybdenum porphyry system at the Viper Prospect, Stock Titan reported on October 30, 2026. Harvest Gold reported a 1.90 g/t gold intercept over 5.4m from the Northern Area of Mosseau and is still drilling the Central Area, with results expected in January 2026, Business & Financial reported on October 30, 2026.

Redstone's March 2027 Drilling Quarter

The West Musgrave reverse circulation program is scheduled for the March 2027 quarter, and sampling at Rudall East and Cockatoo Rocks is planned across the December 2026 and March 2027 quarters.
