ASX Announcement ASX Codes: SRN and SRNOB
YIDBY GOLD PROJECT
MAIDEN DRILLING PROGRAM AT YIDBY GOLD PROJECT COMPLETED
-
Maiden reverse circulation (“RC”) drilling at the project has recently been completed.
-
Prospects drilled include: Yidby Road, Cashen’s Find, and Delaney Well.
-
Twenty holes drilled for a total of 1,687 metres.
-
Majority of holes reported strong veining with metal sulphide mineralisation similar to descriptions in reports on historic drilling.
-
Strong indications of shearing, alteration and veining observed in nine of twelve holes drilled at Yidby Road Prospect, with veining and mineralisation observed in all holes at
Cashen’s Find and Delaney Well Prospects.
- Massive quartz-carbonate veining up to 35m in down-hole width intersected
Surefire Resources NL (ASX:SRN, " the Company " or “ SRN ") is pleased to announce the completion of its maiden reverse circulation drilling program at the Yidby Gold Project. A total of 20 RC holes were drilled for an aggregate of 1,687 metres. The drilling targeted significant and high-grade gold intersections from historic drilling at the Yidby Road, Cashen’s Find, and Delaney Well Prospect areas.
The program was initially delayed due to contractor availability and progress was slow to moderate with average daily penetration of approximately 100m. Drill holes were collared at -60 degrees dip with the azimuth of holes being towards the east and west. Samples were taken as composites of 3m or 4m with 1m splits samples also being collected where veining, alteration, and/or metal sulphide mineralisation was present. A total of 777 samples were collected and submitted to NAGROM Laboratories of Kelmscott for multi-element analysis. 301 of these were 1m splits with the remainder being the 4m or 3m composites.

Figure 1 Drilling at Yidby Road Prospect
Yidby Road Prospect
At Yidby Road Prospect, a total of twelve holes were drilled with the deepest being 160m. Drillholes included YBRC001 to YBRC012 for an aggregate of 1,225m. Holes typically encountered a 10m to 20m thick layer of pisolitic transported material, and then through weathered in-situ bedrock and clay saprolite down to approximately 40-50 metres. Fresh rock included high magnesium basalt, pyroxenites altered to talc-chlorite schist, and a mineralised quartz-feldspar porphyry with significant amounts of smoky quartz-carbonate veining associated with it. Sulphides present included fine to course euhedral pyrite, pyrrhotite, arsenopyrite, and minor galena. Several drillholes intersect significant amounts of mineralised quartz-feldspar porphyry with abundant veining and fracturing. These included YBRC005, YBRC006, YBRC007, YBRC008, YBRC009, YBRC010.

Cashen’s Find Prospect
At Cashen’s Find, situated approximately 1.8 kilometres to the north of Yidby Road, a total of three RC holes were drilled targeting the mains artisanal costean referred to as Cashen’s Find. Historic drilling also targeted this working which resulted in:

|---|---|---|---|---|---|---|---|---|---|---|---|
| Hole ID | (m) | (m) | (m) | (g/t) | **Type ** | MGA | MGA | ||||

| CFRC3 | 15 | 20 | 5 | 1.09 | RC | 525971 | 6753616 | 300 | -60 | 90 | 35 |
The holes at Cashen’s Find included CHRC001-CHRC003 with each hole being drilled to a depth of 50m. Each hoe intersected the quartz veined feldspar porphyry unit that outcrops within the costean. Mineralisation occurs on the hanging wall and footwall contact between the porphyry and the surrounding foliated metabasaltic rocks.
Delaney Well Prospect
At Delaney Well Prospect a total of five holes were drilled (DWRC001 to DWRC005) for 312m down to a maximum depth of 72m. The holes were targeting a north-south trending shear zone with numerous excavations along its strike length. Historic drilling reported significant and high-grade results outlined in the table below:
| From | To | Interval | Au | Hole | Easting | Northing | RL | Dip | Azimuth (mag) |

| DLRC002 | 35 | 37 | 2 | 2.32 | RC | 527318 | 6760140 | 300 | -60 | 90 | 64 |
The gold workings occur at the junction point between a north-westerly trending shear zone, and a north trending structure. The controls on the mineralisation remain to be better understood, and it appears that potentially steep plunging shoots have not been adequately tested by the shallow historic drilling. Lithologies drilled included fresh tholeiitic basalt with quartz veining.
