Flynn Gold Ltd (ASX:FG1) has achieved average gold recovery of 94.5% from metallurgical tests on the Trafalgar Prospect within the company’s 100%-owned Golden Ridge Project in northeast Tasmania.
Initial metallurgical tests, to establish whether the gold at Trafalgar was readily recoverable using conventional cyanide leaching processes, have been successfully completed on 26 drill samples.
The 26 samples across a wide range of gold grades and mineralisation types — three oxide and 23 fresh rock in the sulphide zone — were tested for gold recovery by cyanide using a bottle roll leach (LeachWELLTM) test at Australian Laboratory Services Pty Ltd to record the average gold recovery of 94.5%.
Flynn Gold managing director and CEO Neil Marston said: “With the recent completion of Phase 2 drilling at the Trafalgar Prospect at Golden Ridge in northeast Tasmania, the company has undertaken its first round of metallurgical tests to establish the potential gold recovery using conventional processing methods.
“Undertaking these tests early is vital in determining if the gold at Golden Ridge can be recovered using well-established technology.
"To achieve an average gold recovery result of 94.5% is extremely encouraging, especially as most samples were from the fresh rock ‘sulphide zone’. Follow-up test work is now being planned.
“Meanwhile, the company continues drilling on other projects in Tasmania with the rig presently testing for depth extensions of gold and critical minerals at the Firetower project.”
Final assays received
All assay results have now been received from the phase 2 drilling at Trafalgar, which was completed in late August. With all drilling results received, the company is now updating the geological model of the Trafalgar prospect to identify the best drilling targets for testing with follow-up drilling.
Warrentinna Project diamond drilling
Flynn also reports that diamond drilling at its Warrentinna Project in Tasmania has concluded with two planned holes successfully completed for a total of 357 metres.
Core logging, cutting and sampling have been completed with samples being processed through the laboratory for analysis. The company expects to report assay results in the coming weeks.
Additionally, diamond drilling at the company’s Firetower project has commenced with the aim of testing for depth extensions of the main gold-cobalt-tungsten-copper mineralised zone identified in previous drilling. Further details will be provided once this drilling is completed.
