Assays from recent drilling at Surefire Resources’ (ASX: SRN) wholly-owned Yidby gold project in Western Australia has confirmed the mineralisation continues outside of known targets and geochemistry anomalies.
New results grading up to 20.81 grams per tonne have been returned from the campaign, which commenced in April and comprised 25 reverse circulation holes for a total 3381 metres.
Drilling was designed as a broad-spaced follow-up over previously untested gold targets and to test the continuity of mineralisation along strike and along dip.
Holes were sampled on a 4m composite basis and Surefire planned to then sample the 1m intervals over any horizon showing gold anomalism.
All drillholes are reported to have intersected multiple sulphide intercepts with gold providing wide mineralised envelopes in a north-west trend over several kilometres and open in all directions.
Pleased with results
Managing director Paul Burton said he was pleased with the results to date.
“The results from the 4m composites are encouraging and continue to show mineralisation extending beyond our previous intersects,” he said.
“There are clear mineralising trends evident which provide targets for future drilling as the Yidby project evolves.”
Mr Burton said the 1m intervals were currently being assayed, with results expected in the coming weeks.
The company has also engaged Perth-based Southern Geoscience to conduct a close-spaced detailed review of the Yidby geophysical data.
It is expected to provide a more detailed lithology and structural interpretation extending from the drilling program, with a view to identifying untested and along-strike anomalous areas for follow up geochemistry or exploration.
Project acquisition
Surefire acquired the Yidby tenements in 2020 and has systematically explored the area using geochemistry and geophysics to define drill targets which led to the discovery of a gold system beneath transported overburden.
The project is well located within a district-scale gold mining area, 350km from Perth.
Mr Burton said Yidby was emerging as a large mineralised system across 114 square kilometres of the southern Yalgoo-Singleton greenstone belt.
The region hosts a number of sizeable gold deposits including Minjar (1.1 million ounces), Kirkalocka (1Moz), Mount Gibson (2.75Moz) and Rothsay (540,000oz).
Several companies have drilled on and around Yidby over the years, including former mining major WMC Resources, Capricorn Resources, Normandy Gold and WCP Resources (now known as Piedmont Lithium, ASX: PLL).
