Highlights
- Surefire Resources has received assay results with a range of up to 20.81 g/t gold for 4m composite samples from the Yidby Gold Project.
- The assays confirm that gold continues outside of known targets and geochemistry anomalies.
- One metre samples from key intervals in composite samples have been selected for laboratory assay.
- Also, major structural control to mineralisation has been interpreted from the Yidby and Fender shear zones providing future targets.
Australian mineral explorer Surefire Resources (ASX: SRN) has received assay results from its recent reverse circulation (RC) drilling programme at its 100%-owned Yidby Gold Project in Western Australia.
The company had completed 25 RC drill holes for 3,381m in April 2023. It was a broad spaced follow up drill campaign covering gold targets which remained untested.
The continuity of mineralisation along strike and along-dip from the gold mineralisation discovered at the Yidby Project was also tested during the campaign.
Sampling of the drill holes was done on a 4m composite basis to then sample the 1m intervals over any horizon with gold anomalism.
Assays indicate gold continuity
All drill holes hit multiple sulphide intercepts with gold providing wide mineralised envelopes in a northwest trend over several kilometres.
The assays have delivered broad gold intersections in each drill hole with a maximum result up to 20.81 g/t Au in YBRC077 119 to 120m and have shown continuity in areas without previous geochemical anomalies (YBRC080 12m@ 0.96g/t Au from 96 to 108m) data importantly indicating the area remains open in all directions.

Future Targets
At this stage, two main gold mineralised shears have been detected from drilling data - the Fender shear and the Yidby shear.
A feature of the Yidby shear is localised spectacular gold grades, up to 82.5g/t Au (YBRC019 from 150 to 151m). Most of the mineralisation in the Yidby shear is located outside of the QFP in the Meta-Ultramafic lithology.
The Fender shear, is a repetition of the Yidby shear, located 400m to the west of Yidby. The Fender shear has the same orientation, in strike and dip, as the Yidby shear.
The company says that significant structural control to mineralisation interpreted from the Yidby and
Fender shear zones would provide future targets.
Path forward
The ASX-listed firm has hired SGS (Southern Geoscience) for a review of the Yidby geophysical data. This will help in getting a thorough lithology and structural interpretation from the SRN drill program and thereby help in detecting anomalous areas which are untested along strike for follow-up geochemistry or drilling exploration.
The results from the 1m intervals samples are still awaited. It will provide details on the type of coarse gold in the area.
Stock price performance
The company shares have jumped over 70% on the Australian Securities Exchange (ASX) in the past six months. The share price was spotted trading at AU$0.017 on 01 June 2023, with a market cap of over AU$28 million.
