Surefire Resources has announced that the results of the metallurgical column leach test work at its Yidby Gold Project, located on Western Australia’s Great Northern Highway, achieved a 68 per cent increase in gold content compared to previous drill assay results.
Surefire Resources said that the increase is due to the prominence of coarse gold (+0.5mm), indicating that there is a significant underreporting of previous gold grades.
The company said that the column leach results were from non-agglomerated coarse material (6.33mm) and achieved a 66.3 per cent recovery and indicate that a finer crush size would further improve gold recovery providing a significant upside for the resource grades.
Drilling intercepts to date contain mineralisation in zones of high grades gold (Au) with 5g/t Au up to 82 g/t Au and broader zones with 0.2g/t Au to 1.5g/t Au.
Surefire Resources said that the programme has highlighted the potential for a low-cost heap or vat leach operation.
The Yidby Gold Project is a large gold system located in the Yalgoo-Singleton Greenstone Belt in the Murchison Province of the Yilgarn Craton and contains significant mineralised zones up to 80m wide, currently extending over a 3km strike length, open along strike and at depth.
Surefire Resource’s Managing Director, Paul Burton, said, “Metallurgical test work results always provide more reliable and insightful information than original drill results.
“For Yidby these results are very encouraging and provide a solid step up for the project at a time when Gold is of increasing value. This continues to be a great asset for the Company and I look forward to presenting further updates on this exciting project”.
