GBM Resources Limited (ASX: GBM) has reported a significant gold intersection located over 100 metres outside the existing Mineral Resource Estimate at the 309 deposit, part of the company’s Twin Hills Gold Project in the Drummond Basin, Queensland.
The results are from the latest assays returned from a further three drillholes of the thirteen planned in the Stage 1 drilling program. These assays include a standout intercept from drillhole TNDH012 of 37 metres at 5.00 grams per tonne gold from 225 metres depth. This interval contains exceptionally high-grade zones including 1 metre at 77.25 grams per tonne from 228 metres and 3 metres at 29.96 grams per tonne from 251 metres.

These intersections are located significantly outside the current Mineral Resource boundary, confirming the presence of high-grade gold mineralisation well beyond previously defined limits. This discovery highlights the potential to substantially expand the gold resource at Twin Hills with continued step out drilling.
The cross-sectional view of drillhole TNDH012 demonstrates that mineralisation persists across broader structural zones than previously modelled. The new data will contribute to refining the geological interpretation and resource estimation of the 309 deposit.
This news comes as GBM continues exploration and development activities across its assets in Queensland. The Twin Hills Gold Project currently hosts a Mineral Resource of approximately 1.0 million ounces of gold. The company has stated that the continued success of the Stage 1 program will inform future drilling and potential resource updates.
The intersection of mineralisation at such grades and extent provides renewed confidence in the broader gold system at Twin Hills and supports GBM’s strategy to unlock further value from its existing projects through focused resource growth initiatives.
