Surefire Resources NL (ASX:SRN) discovered a new mineralised gold trend in a recent reverse circulation (RC) drilling campaign at the Yidby Gold Project in Western Australia
This new Western Zone occurs 400 metres northwest of the Yidby Road deposit, significantly increasing the footprint of gold mineralisation at the project
This new trend exhibits large widths with typically higher-grade gold within a mineralised halo with notable results including:
- 60 metres at 1.04 g/t gold from 32 metres, including 4 metres at 10.40 g/t from 72 metres;
- 20 metres at 0.43 g/t from 104 metres; and
- 32 metres at 0.32 g/t from 144 metres.
Moving forward, Surefire has scheduled diamond drilling of six oriented diamond drill holes at Yidby, expected to kick off within the next four weeks.
Drill program
Surefire’s drill program comprised 2,752 metres across 23 RC holes and was primarily aimed at testing magnetic metals ions (MMI) surface gold geochemistry anomalies.
The Surefire model predicts the parallel gold mineralised zone, at present called the Central Zone, will feature wide gold mineralised zones with localised higher gold grades, similar to that seen in YBRC059.
Competency contrasts between the more ductile mafic/ultramafic country rock and the brittle, late-stage quartz porphyry intrusives are considered ideal hosts for gold mineralisation here.
Forward plan
Surefire expects to receive the balance of the drill sample assays from this program within the next six weeks. The delay in receipt of assays is due to reported lab bottlenecks.
The company has scheduled diamond drilling of six oriented holes for about 800 metres of HQ core.
The oriented diamond drill core will provide valuable data, re alteration assemblages and structure, vital for a gold deposit without outcrop such as Yidby.
