Highlights

Reach reported final assays from a 163-hole reverse circulation grade-control programme at Murchison South.
The programme totalled about 4,236 metres across the first five proposed NW Pit Mining benches.
Hole 26MSGC0127 returned 9 metres at 4.7 g/t gold from 6 metres, including 2 metres at 18.5 g/t.
The results are being incorporated into short-term mine planning, with mining proposed for 2027.

Reach Resources Limited (ASX:RR1) is an Australian mineral explorer and developer with a focus on the Murchison South Gold Project near Paynes Find in Western Australia. In November 2026 it reported completion of grade-control drilling at its proposed NW Pit. The programme provides closely spaced geological information for mine scheduling, but reported assays are not the same as completed production or an updated ore reserve.

Final Assays from the NW Pit Programme

The final 40 reverse circulation holes completed the company’s 163-hole grade-control programme, totalling approximately 4,236 metres. Testing covered the first five proposed mining benches at NW Pit. Hole 26MSGC0127 returned 9 metres at 4.7 grams per tonne gold from 6 metres, including 2 metres at 18.5 grams per tonne. Another hole, 26MSGC0120, returned 15 metres at 1.9 grams per tonne from 8 metres in an area previously modelled as lower grade. Reach Resources (ASX:RR1) also identified mineralisation in five consecutive holes along one grade-control line. These assay intervals describe local drill intersections, not a mine-wide grade.

Closer Spacing Refines Geological Interpretation

The programme tightened drilling spacing from approximately 20 metres by 20 metres to 10 metres by 10 metres. This was designed to improve the position of ore and waste boundaries ahead of excavation. Across the full campaign, 13 holes returned intervals above 5 grams per tonne gold and five exceeded 10 grams per tonne, including a previously reported 2-metre interval at 24.6 grams per tonne. Reach Resources (ASX:RR1) says the results broadly validate the existing NW Pit geological model, while some intersections are wider or higher grade than previously modelled. Local differences can assist scheduling and ore control, but do not automatically increase the overall estimated resource.

Resource Context and Proposed Mining

The existing Murchison South mineral resource cited by the company is approximately 844,000 tonnes at 3 grams per tonne gold, containing about 80,000 ounces. Some grade-control intervals are outside the current modelled resource boundary. Reach Resources (ASX:RR1) is working with its mining partner, SMS Mining, part of Andel Resources, under a right-to-mine arrangement announced during August 2026. The partner is using grade-control results to refine short-term mine scheduling. Proposed first mining during 2027 remains dependent on the relevant approvals and operational arrangements. The agreement is not evidence that ore has already been mined or sold. The economic allocation between the project parties depends on contract terms.

Approvals and Remaining Development Work

The company has indicated an intention to submit its Murchison South mining proposal during November 2026. Assays from a separate approximately 2,000-metre step-out programme completed earlier in 2026 are also awaited. Those results could inform work outside the proposed initial pit, but they should not be anticipated as confirmed resource additions. Reach Resources (ASX:RR1) must align mine plans with permissions, contractor availability and actual grade reconciliation as excavation proceeds. Grade control helps reduce uncertainty in early benches; it cannot eliminate variations in gold distribution or guarantee future production. Further drilling and revised modelling may be needed before the company can assess any longer-term extensions.

Key Insights

Reach Resources (ASX:RR1) has completed a close-spaced grade-control campaign that supports refinement of the NW Pit geological model. The next milestones concern mine scheduling, approvals, separate step-out assay results and the planned transition towards mining in 2027.
