Gorilla Gold Reports 340% Surge in Contained Gold at Mulwarrie Project in WA

Gorilla Gold Mines (ASX: GG8) has unveiled a 340% increase in contained ounces at its Mulwarrie gold project north of Kalgoorlie in Western Australia.

A concerted program of drilling at Mulwarrie has helped Gorilla Gold release an upgraded mineral resource estimate (MRE) of 3.0 million tonnes grading 3.6 grams per tonne for 350,000 ounces of contained gold, including a 29% increase in grade over a November 2018 MRE previous owner Bardoc Gold had generated.

The update at Mulwarrie has lifted Gorilla Gold’s WA group gold MRE to 720,000oz at 3.9g/t and total group MRE to 1.2Moz at 4.3g/t.

Low-Cost Ounces

Chief executive officer Charles Hughes noted Gorilla delivered the additional ounces at a discovery cost of approximately $15 per ounce.

“After just six months of drilling, we have been able to take this project well and truly to the next level with a major uplift in the ounces and grade as part of this pivotal MRE update,” Mr Hughes said.

“The true potential of the Mulwarrie project is really starting to shine through and, as a result of this MRE update, we’re now in a much better position to convey the scale of the opportunity at Mulwarrie to the market.”

“Gorilla has now added 540,000 ounces of high-grade resources across its West Australian projects so far in 2025, with another major resource update planned for the back end of this year from Comet Vale.”

Project Consolidation

Along with its aggressive drilling strategy, Gorilla Gold has focused on consolidating the tenure at Mulwarrie since acquiring the project in November 2024.

Mulwarrie, which lies among granted mining leases in a region with multiple operational gold mills within a 100km radius of the project area, was tenure-constrained and caught up in merger and acquisition activity after the discovery of the main mineralisation in 2017.

Gorilla is also continuing with its exploration and growth strategy at the nearby Comet Vale project – which the company now owns 100% of – with five rigs currently operating and a major MRE update due in Q4 2025.

Mulwarrie Major Focus

The updated Mulwarrie MRE followed the company’s successful drilling at the project during the June quarter, in which it defined multiple parallel lodes from surface, extending over a strike length of more than 1.3 kilometres and to a depth of at least 350m.

Gorilla Gold also undertook a significant drilling program at Comet Vale’s Lakeview prospect, which now extends over a strike length of more than 700m and 300m down-dip and remains open with multiple mineralised structures.

“At Gorilla, we pride ourselves on doing what we say we will do; this quarter is a great demonstration of that, and we are just at the beginning of our journey to build a substantial high-grade gold inventory in the heart of WA’s goldfields,” Mr Hughes added.
