- A 2,298m RC drill program has been concluded at Yidby. Several anomalies were drill tested targeting numerous high grade MMI anomalies and identified zones with quartz-carbonate-sulphide alterations.
- Samples have already been shared for analysis and the results could take up to 8 weeks.
- The flora and fauna study at the Money MMI Geochem anomaly has also been concluded.
Surefire Resources NL (ASX:SRN) has shared updates on its latest exploration activities, including RC drilling at the Yidby gold project and Mobile Metal Ions (MMI) soil sampling program at the Money soil anomaly in Southern Yidby.
Shares of Surefire surged ~7% to AU$0.015 on 25 October 2021 with a market capitalisation of AU$15.46 million.
Large zones prospective for mineralised quartz and sulphide identified
Surefire has already concluded two phases of drilling, covering 22 RC holes aggregating to 2,298m. The first phase focused on delineating potential gold mineralisation from the extensive MMI soil sampling anomalies, west of the Yidby Road gold deposit, while the second phase utilised an Explorac HC220 rig to drill deep holes beneath the deposit.
Several anomalies were drill tested targeting numerous high grade MMI anomalies and identified zones of quartz-carbonate-sulphide alterations. At the Yidby gold deposit, three RC holes (YBRC41-YBRC43) were drilled up to a depth of 274m.

These holes tested the depth extensions along strike of the previously drilled hole, YBRC017, which recorded broad intercepts including 100m with 0.53g/t from 96m. The geological logging so far has identified 18m of quartz-sulphide alteration from 212 within YRBC041.
These mineralised zones are considered prospective for additional extensions to the known Yidby Road deposit with past intersections of –
- YBRC008 - 40m with 3.01g/t gold from 24m, including
4m with 26.57g/t gold from 52m
- YBRC007 - 56m with 1.97g/t gold from 44m
- YBRC019 - 32m with 3.68g/t gold from 150m
- YBRC035 - 26m with 2.02g/t gold from 126m
Samples have already been shared for analysis and the results could take up to 8 weeks due to high demand.
For surface topography survey, Surefire had engaged Arvista, which completed the process using drone technology to define mineral resources and conduct studies at the Yidby Road gold deposit.
Mobile Metal Ions (MMI) soil sampling program
Previously, Surefire had announced that large anomalies were identified at Yidby after the August 2021 sampling program. The geochemical data has now been thoroughly interpreted to delineate anomalous trends. Among these, the coincident gold and copper trends, and the large banded-iron ridge with parallel quartz veins to the west are believed to be significant.

The mineralisation is interpreted to be not associated to the Yidby Road despot system which traverses across the northern contact of the Money MMI anomaly.
The latest “Money Anomaly” is an extensive northwest trending 1,000m x 250m area with MMI gold-in-soil anomalies. An array of parallel structure has been interpreted to be associated to copper and gold mineralisation but may be associated with a wide or flat dipping structure. The flora and fauna study at the Money MMI Geochem anomaly has also been concluded.
