Highlights

Hole 26MBRC070 returned 12 metres at 3.85 grams per tonne gold from 50 metres, including 1 metre at 30.03 g/t.
The company called it the best gram-metre intercept at Marble Bar, with mineralisation still open along strike and at depth.
Assays for the final 14 holes of the 20-hole Razorback program are in; three holes returned no significant intercepts.
A 2,000 metre diamond program starts in November, with results expected in the first quarter of 2027.

Final assays are in at Razorback, and the best is a 12 metre run at 3.85 grams per tonne gold with a one-metre spike at 30.03. MB Gold Limited (ASX:MBG) announced on 28 October 2026 that assays have been received for all 14 remaining holes of a 20-hole reverse circulation program at the Razorback Prospect, drilled in September. The full Phase 2 program totalled 4,308 metres across the Twin Veins and Razorback areas.

Best intercept at the project

Hole 26MBRC070 returned 12 metres at 3.85 grams per tonne gold from 50 metres, including 1 metre at 30.03 g/t from 57 metres, which the company described as the best gram-metre intercept at the project. It said the 30 g/t single-metre result supports the potential for a high-grade resource, but no Mineral Resource has been declared. Mineralisation remains open along strike and at depth and is a focus for extensional drilling in 2027.

Other results from the final holes

Intercepts use a 0.3 g/t gold cut-off with up to 2 metres of internal dilution. Other results included 5 metres at 1.13 g/t from 86 metres in 26MBRC071, 3 metres at 1.95 g/t from 68 metres in 26MBRC076, 2 metres at 2.70 g/t from 36 metres in 26MBRC077 and 2 metres at 2.13 g/t from 20 metres in 26MBRC078. Hole 26MBRC081 returned 1 metre at 2.37 g/t from 118 metres. Holes 26MBRC069, 072 and 074 returned no significant intercepts, and 4 metres at 0.48 g/t in 26MBRC075 was a four-metre composite sample.

Earlier Razorback results

Previously reported intersections included 9 metres at 4.03 g/t from 60 metres in 26MBRC066, including 3 metres at 10 g/t, and 8 metres at 2.50 g/t from 64 metres in 26MBRC068, including 1 metre at 14.01 g/t. Hole 26MBRC064 returned 7 metres at 2.94 g/t from 9 metres and 4 metres at 3.65 g/t from 24 metres. At Twin Veins, an earlier result was 7 metres at 2.52 g/t from 67 metres in 26MBRC052.

Technical details

JDC Drilling used a Hydco 250 rig. Samples were cone split at one-metre intervals, with four-metre composites in some cases, and assayed in Perth by Jinning Testing and Inspection Laboratory using 50 gram fire assay with an atomic absorption finish. The company estimated recovery above 90 per cent through mineralised zones. The zones dip steeply north at 70 to 80 degrees and strike east-south-east to west-north-west at Razorback. True widths have not been determined, so all intercepts are downhole lengths. Exploration manager Charles Gillman, a Competent Person under the JORC Code 2012, prepared the information.

Next steps

A 2,000 metre diamond drilling program is scheduled to begin in November. It will target chargeable anomalies identified by a dipole-dipole induced polarisation survey at Murphy Well and Twin Veins, and include holes at Twin Veins and Razorback to gather structural data and metallurgical samples. Core processing is expected to run through December and January, with results due in the first quarter of 2027. Planning continues for further reverse circulation drilling at Razorback in 2027, after the summer heat and rain period.

Drilling results are not a resource estimate, and no metallurgical results or resource estimate have been reported for Razorback.
