Reach Resources (ASX:RR1) has received final assay results from its 163-hole reverse circulation grade control drilling program at the proposed NW Pit within the Murchison South Gold Project near Payne's Find, Western Australia, with the completed program validating and in several areas exceeding the company's existing geological and resource model.

Key Points

  • All 163 RC holes for approximately 4,236 metres have now been completed across the first five proposed mining benches at the NW Pit
  • Final 40 holes include a best result of 9 m @ 4.7 g/t Au from 6 m, including 2 m @ 18.5 g/t Au, in hole 26MSGC0127
  • Across the full program, 13 holes returned intervals above 5 g/t Au and five returned intervals above 10 g/t Au, peaking at 2 m @ 24.6 g/t Au
  • Five consecutive holes on a single grade control line (26MSGC0125 to 26MSGC0129) all intersected significant mineralisation from at or near surface
  • Mining leases M59/790, 786 and 799 remain yet to be drilled by the company, with the filing noting significant exploration upside

Final Assay Results from NW Pit Grade Control Program

The final 40 holes from the grade control program at the NW Pit returned further high-grade near-surface gold results. Notable intersections include 10 m @ 1.9 g/t Au from surface and 10 m @ 1.6 g/t Au from 18 m in hole 26MSGC0126, 15 m @ 1.9 g/t Au from 8 m in hole 26MSGC0120, 18 m @ 1.4 g/t Au from 4 m in hole 26MSGC0125, and 11 m @ 0.9 g/t Au from surface in hole 26MSGC0128. The best results from the final batch came from the southern part of the NW Pit, where five consecutive holes on a single grade control section line intersected significant mineralisation from at or near surface.

Program Validates Resource Model with Tighter 10m x 10m Drill Grid

The grade control drilling was completed on a 10 m x 10 m grid, tightened from the approximately 20 m x 20 m spacing used in resource drilling. According to the filing, this closer spacing refined the local distribution of grade, including several zones of higher grade and greater width than modelled. The filing states the results are consistent with the quartz-vein-hosted, nuggety style of gold mineralisation at Murchison South. Mineralisation outside the current Mineral Resource Estimate domains was also intersected, which the filing describes as upside to be included in the grade control interpretation. Holes on pit margins and in the hanging wall returned results consistent with the model's interpretation of waste in those areas.

Mine Scheduling to Progress Under Andel Right to Mine Agreement

The complete dataset from the grade control program will be used by Andel Resources Pty Ltd subsidiary SMS Mining Pty Ltd to finalise short-term mine scheduling for the NW Pit ahead of proposed first ore production. The grade control program was completed to inform mining under the binding Right to Mine Agreement announced on 18 August 2026. The filing states that Andel's focus now turns to finalising the grade control interpretation and estimate, which will be used to refine the mine plan and short-term schedule for the NW Pit. The company also noted that similar works are planned at its Central and South pits.
