Goldman Drilling 700m beyond resource highlights strong growth potential and expanding corridor-scale opportunity
Gorilla Gold Mines Ltd (ASX:GG8) has reported encouraging step-out drilling results from its 100%-owned Mulwarrie Gold Project near Kalgoorlie, confirming high-grade mineralisation extends well beyond the current 350,000oz resource.
The latest drilling has intersected gold mineralisation more than 700 metres along strike from the existing Mineral Resource Estimate (MRE), marking the furthest step-out to date and reinforcing the project’s growth potential.
Key drill results:
- 3.4m @ 9.0g/t Au from 376.9m (MWEX115)
- 0.7m @ 24.8g/t Au from 110.3m (MWEX111)
These results sit approximately 700m south along strike from previous drilling and demonstrate continuity of high-grade mineralisation beyond the current resource footprint.
In parallel, soil sampling has outlined multiple new gold anomalies outside the MRE area, including:
- A ~2.5km-long gold-in-soil anomaly northwest of the resource
- More than 11km of strike of new anomalies identified at Mulline, 12km north of Mulwarrie, highlighting camp-scale exploration upside
Gorilla has also strengthened its landholding between Mulwarrie and Mulline through a tenement acquisition from Hamelin Gold Limited, improving continuity across a highly prospective mineralised corridor.
Drilling remains ongoing, with two diamond rigs operating as part of a broader 150,000m program aimed at expanding and upgrading the Mulwarrie resource base.

The Mulwarrie Project remains significantly under-explored, and these exciting step-out drilling results demonstrate the scale of the opportunity ahead of us. Intersecting high-grade gold more than 700 metres beyond the existing resource boundary, as shown in Figure 1 below, highlights the potential to materially expand the Mulwarrie Mineral Resource through continued drilling in 2026.
Our recent soil sampling has delineated multiple new walk-up drill targets along an extensive corridor of mineralisation extending from Mulwarrie South through Mulwarrie Central, where the current MRE has been defined, up to Mulwarrie North. Extensive zones of soil anomalism have also been defined up to Mulline, along strike of the OBM Lady Gladys deposit as well as anomalies along strike of the recent OBM Little Gem discovery. A total of 30km of specific targets are now defined at the Mulwarrie Project, demonstrating real, district-scale multi-million ounce potential, and prompting us to consolidate this ground through the transaction with Hamelin Gold, where we look forward to integrating this area into exploration programs subject to prioritisation.
Importantly, we are seeing strong geological parallels with the success achieved at Comet Vale during 2025, where the identification of similar anomalies ultimately translated into the discovery of an additional 750,000oz through systematic drilling. We’ve seen a really good strike rate of converting these high grade gold targets into high grade gold resources and we look forward to further success on both projects.
Having added more than 1.3 million ounces at an average grade of 3.7g/t through exploration during 2025, Gorilla is well positioned to continue growing our existing resource base while simultaneously increasing resource confidence and scale across the portfolio in 2026.
