- Further strong results at Lone Sister
- Additional mineralisation returned from 309 outside of the current MRE
- Twin Hills MRE on track for completion by end of November 2026
- Testing of high-priority targets at Twin Hills within the Lone Sister/309mineralised corridor on-going
GBM Resources (ASX: GBM) has obtained further positive assay results from the ongoing stage two drilling program at the Twin Hills gold project within the Drummond Basin, Queensland.

The latest results include a broad 50m at 2.01 grams per tonne (g/t) gold from 246m, entirely outside the current Lone Sister mineral resource estimate (MRE), together with further strong intersections at both Lone Sister and 309.
“These are excellent results from our stage two drilling program, particularly at Lone Sister, where broad zones of gold mineralisation and higher-grade intersections continue to demonstrate the quality of the deposit,” CEO, Daniel Hastings, said.
“The 50m at 2.01 g/t Au intersection, entirely outside the current MRE, is particularly encouraging and adds to the strong results returned from Lone Sister throughout the program.”
Mr Hastings said a key objective of stage two drilling has been to improve resource confidence and increase the proportion of Measured and Indicated resources.
“The results at both deposits provide a strong basis for improved resource classification, with potential for resource growth and grade uplift,” he said.
“With laboratory backlogs cleared and the MRE database quarantined, we remain on track to complete the updated resource at the end of November. Combined with our recent highly encouraging metallurgical results, this will provide the basis for a formal decision to progress Twin Hills to feasibility studies.”
The stage two drilling program at Twin Hills has focused on extending mineralisation beyond existing MRE boundaries, improving geological and grade confidence and better defining higher-grade mineralised zones.
Drilling at both Lone Sister and 309 has returned substantial gold intersections within and beyond existing resource boundaries, providing additional drill coverage and an improved understanding of the geological controls on mineralisation. The laboratory backlog has now been cleared and the drilling database quarantined, with the updated MRE on track for completion by the end of November 2026.
The stage two program has substantially increased drilling coverage and improved the company’s understanding of the geometry, continuity and grade distribution of mineralisation within the deposit. The latest results build on previously reported drilling including 37m at 2.40 g/t Au from 285m and 52m at 2.77g/t Au from 299m.
The standout new result is 50m at 2.01 g/t Au from 246m including 10m at 4.20 g/t Au from 279m and 3.0m at 6.99 g/t Au from 293m. The entire 50m intersection is located outside the current MRE, confirming additional mineralisation beyond the existing resource boundaries.
Further strong results include 16m at 2.96 g/t Au from 430m including 6.0m at 3.95 g/t Au from 433m and 10m at 3.04 g/t Au from 323m, including 1.0m at 16.95 g/t Au from 331m.
