Gorilla Gold Mines continues to expand its North Kalgoorlie Hub resource with standout high-grade intercepts at Sovereign and a promising shallow gold find at Lady Margaret, signalling robust exploration momentum.
- High-grade intercepts extend Sovereign deposit beyond 410,000oz resource
- New shallow gold discovery at Lady Margaret returns 2m at 5.9g/t Au
- North Kalgoorlie Hub resource base totals 1.2Moz at 3.7g/t Au
- Four rigs active across Comet Vale and Vivien projects
- Ongoing engineering and permitting work alongside exploration
Sovereign Deposit Delivers Exceptional High-Grade Intercepts
Gorilla Gold Mines Ltd (ASX:GG8) has reported a fresh tranche of high-grade gold intercepts from its Sovereign deposit at the Comet Vale Gold Project, part of its North Kalgoorlie Hub. The results reinforce Sovereign’s status as a cornerstone asset, with assays including 1.2 metres grading 31.5 grams per tonne (g/t) gold from 69.1 metres and a broader 7.6 metres at 5.1g/t Au from 251.3 metres. These hits extend mineralisation well beyond the current resource footprint of 410,000 ounces at 4.3g/t Au, underscoring the deposit’s considerable growth potential.
Mineralisation at Sovereign is hosted in quartz veins associated with sulphide minerals such as pyrrhotite and chalcopyrite, often with visible gold, and occurs along shear zones at lithological contacts. The ongoing drilling campaign continues to delineate multiple parallel lodes, expanding both strike length and depth potential. This latest batch of results includes several intercepts above 6g/t Au, highlighting the high-grade nature of the system.
Lady Margaret Prospect Emerges as New Shallow Gold Target
Approximately one kilometre west of Sovereign, initial scout drilling at the historically significant Lady Margaret prospect has intersected encouraging shallow gold mineralisation, including 2 metres at 5.9g/t Au from 18 metres. Lady Margaret, first discovered in the late 19th century and noted as the highest-grade producer in the area historically, remains wide open for further expansion. This discovery adds a new dimension to Gorilla Gold’s exploration pipeline within the North Kalgoorlie Hub, which now hosts over 60 kilometres of high-priority drill targets.
Active Drilling and Strategic Growth Across the North Kalgoorlie Hub
Gorilla Gold currently operates four drill rigs across the Comet Vale and Vivien projects, pursuing both discovery and resource definition objectives. Two reverse circulation rigs are following up recent discoveries at prospects including Diddy Kong, Donkey Kong, and Magilla, while diamond drilling targets high-grade footwall lodes and southern extensions at Sovereign. The company is also advancing engineering, geotechnical, metallurgical, and hydrological studies, alongside permitting activities, laying groundwork for potential development.
With a combined Mineral Resource Estimate of 1.2 million ounces at 3.7g/t Au, the North Kalgoorlie Hub remains historically underexplored despite its proximity to existing milling infrastructure. Gorilla Gold’s aggressive exploration strategy, which added over one million ounces to the Hub’s resource base in 2025, aims to further increase the inventory through systematic drilling and discovery.
Operational and Market Implications
CEO Charles Hughes emphasised the significance of these results, noting that the 2026 exploration campaign is one of the largest in the company’s history. The high-grade growth at Sovereign and the new Lady Margaret discovery provide tangible evidence of the project’s endowment and the company’s capacity to unlock value through targeted drilling. Assay turnaround times are currently slower than usual due to industry-wide demand, which may delay the release of further results but does not diminish the ongoing momentum.
Gorilla Gold confirms no material changes to existing Mineral Resource Estimates for Comet Vale, Mulwarrie, or Vivien projects, maintaining a solid foundation for future resource updates expected later this year. The company’s focus on expanding known deposits while exploring new targets positions it well to capitalize on Western Australia’s prolific gold belt.
Bottom Line?
Gorilla Gold’s latest drilling success at Sovereign and Lady Margaret signals promising resource growth, but assay delays warrant monitoring as the company advances its largest exploration campaign.
Questions in the middle?
- Will further drilling at Lady Margaret confirm a new significant shallow resource?
- How will slower assay turnaround times affect the timing of upcoming resource updates?
- What impact could ongoing permitting and development studies have on project advancement?
