Key Highlights

  • GBM Resources (ASX:GBM) intersected 50 metres at 2.01 g/t gold from 246 metres at Twin Hills, entirely outside the current Lone Sister Mineral Resource Estimate.
  • Further results at Lone Sister include 16 metres at 2.96 g/t gold from 430 metres, outside the resource, and 10 metres at 3.04 g/t gold from 323 metres.
  • Results at the 309 prospect include 27 metres at 1.28 g/t gold from 275 metres and 18 metres at 1.53 g/t gold from 333 metres.
  • The results come from the ongoing Stage 2 drilling program in the Drummond Basin of Queensland.

GBM Resources Limited (ASX:GBM) provided on 9 November 2026 further assay results from the ongoing Stage 2 drilling program at its Twin Hills Gold Project in the Drummond Basin of Queensland. The most notable result is a broad interval of gold intersected entirely outside the current Lone Sister Mineral Resource Estimate, which suggests the mineralised system may extend beyond the existing resource boundary.

The Broad Intersection Outside the Resource

Hole LSDH018 returned 50 metres at 2.01 g/t gold from 246 metres, with higher-grade sections including 10 metres at 4.20 g/t gold from 279 metres and 3 metres at 6.99 g/t gold from 293 metres. GBM says the interval lies entirely outside the current resource estimate.

Hole LSDH022 returned 16 metres at 2.96 g/t gold from 430 metres, also outside the resource, including 6 metres at 3.95 g/t gold. The company describes these results as significant, but they are not presented as a resource update.

Results at Lone Sister and 309

At Lone Sister, hole LSDH014 returned 10 metres at 3.04 g/t gold from 323 metres, including a single metre at 16.95 g/t gold. Mineralisation was also returned from the 309 prospect outside the current resource, including 27 metres at 1.28 g/t gold from 275 metres in hole TNDH042.

Hole TNDH065 returned 18 metres at 1.53 g/t gold from 333 metres, including 3 metres at 5.10 g/t gold, while TNDH059 returned 13 metres at 1.61 g/t gold from 313 metres. The spread of results indicates mineralisation at several depths and locations.

Taken together, the new intervals show several zones with grades above 1 gram per tonne at different depths. The spread of results across Lone Sister and 309 helps define the shape of the mineralised system. The intercepts are presented individually, and whether they combine into a resource would depend on continuity between holes. Investors can track how these intervals are incorporated into any later resource update, which will indicate how much of the material outside the current estimate can be classified.

What Remains Unproven

Intersections outside a resource do not automatically add to the resource, and no revised estimate is provided. Grades vary significantly along individual intercepts, and the continuity of mineralisation between holes will determine how much of the material can be classified.

The company has not released a Mining study, metallurgical outcome or cost estimate yet. Drilling is ongoing, so the results presented may be superseded by later assays.

Final Word

GBM’s latest results indicate that gold mineralisation at Twin Hills extends beyond the boundaries of the current Lone Sister estimate, which is the central point. Whether that extension can be converted into resource ounces will depend on additional drilling and the eventual resource update. The next checkpoint is the completion of the Stage 2 program and any revised estimate.

The completion of the Stage 2 program and any subsequent resource update will show whether the mineralisation beyond the current Lone Sister boundary can be classified and added to the company’s reported resources.
