Gorilla Gold Mines (ASX: GG8) has intersected high-grade mineralisation during step-out drilling at its Mulwarrie project near Kalgoorlie in Western Australia.
The first results came from holes drilled more than 700 metres south-east of the existing mineral resource estimate (MRE), which currently sits at 350,000 ounces grading 3.6 grams per tonne gold.
Best assays were 3.4m at 9g/t gold from 376.9m (700m south along strike of previous drilling and 100m down dip), and 0.7m at 24.8g/t gold from 110.3m (700m south along strike of previous drilling and 100m up dip).
Gorilla Gold Mines will be presenting at The Resources Rising Stars Gather Round investor conference in Adelaide on April 9. Investors can attend free of charge. To see the outstanding company lineup and register, click here.
Mulwarrie Growth Upside
The drilling results – which represent Gorilla’s furthest step-out testing along strike to date – highlight strong potential for the mineralisation to extend well beyond the current resource boundary.
Achieving high-grade assays so far from the existing resource boundary reinforces the growth upside of the Mulwarrie project, which lies on granted mining leases adjacent to the Riverina-Davyhurst haul road 10 kilometres from Ora Banda Mining’s (ASX: OBM) Davyhurst mill, and nearby to other processing mills within trucking distance.
The step-out assays complement results from recent ultra-fine soil sampling over the Mulwarrie resource area, which delineated a 2.5 kilometre-long gold-in-soil anomaly to the north-west of the MRE.
Extensive zones of soil anomalism were also identifed across an 11km strike length at the untested Mulline target 12km north of the MRE, and along strike of Ora Banda’s Lady Gladys and Little Gem discoveries, highlighting Mulwarrie’s significant camp-scale potential.
Consolidating Tenure
Gorilla has now defined 30km of specific targets at Mulwarrie, demonstrating district-scale multi-million ounce potential.
The company has moved to consolidate its tenure through a strategic transaction with Hamelin Gold (ASX: HMG), which holds a tenement between Mulwarrie and Mulline.
Gorilla will acquire E30/561 from Hamelin for a consideration of $200,000 worth of Gorilla shares, escrowed for 12 months and calculated using a five-day volume weighted average price.
The tenement will see Gorilla take ownership of continuous tenure between Mulwarrie and Mulline to strategically align with plans for the project’s regional growth.
“Having added more than 1.3Moz 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,” chief executive officer Charles Hughes said.
