Flynn Gold discovers high-grade mineralisation at Golden Ridge adit
Mapping and vein sampling within the historic Golden Ridge adit in north-east Tasmania has identified a new zone of high-grade mineralisation for owner Flynn Gold (ASX: FG1).
The mineralisation is located at the Link Zone prospect, where underground grab sampling returned high-grade gold assays including 64.4 grams per tonne, 37.6g/t, and 15.9g/t.
Link Zone is situated between the Trafalgar and Brilliant prospects, with all three defining a corridor of high-grade gold mineralisation with a potential strike length of 2.5 kilometres and a vertical extent of at least 500 metres.
Broader zone
The corridor is contained within a broader zone of gold anomalism that forms around the contact of a granite intrusion, with the total length now exceeding 9km.
Previous diamond drilling at Trafalgar returned strong results, with multiple hits grading over 100g/t gold.
Flynn is now conducting a Phase 3 follow-up campaign to test extensions to the known mineralisation.
Historic adit
The historic Golden Ridge adit – recently rediscovered by Flynn – contains multiple sub-parallel, steeply dipping, gold-rich quartz-sulphide veins to a depth of 50m and visible over a zone of up to 30m in width.
The veins are believed to comprise arsenopyrite, pyrite (with minor chalcopyrite), and galena.
Structural evidence suggests they are consistent with similar veins mapped and sampled in historic trenches.
New drill targets
Managing director Neil Marston said the Golden Ridge veins present new drill targets with potential to significantly extend the Trafalgar-Brilliant gold system.
“Our confidence in Golden Ridge as an extensive intrusive-related gold system continues to grow with the results from Link Zone confirming that high-grade mineralisation exists within a well-defined corridor with potential to link Brilliant and Trafalgar,” he said.
“While drilling is ongoing at Trafalgar, our exploration team is working to further extend the gold system at Golden Ridge, which we expect will lead to identifying additional drilling targets similar to the Link Zone.”
This work is being conducted along the contact of the granite intrusion and includes mapping, rock chip sampling, soil sampling and geological modelling.
