SUREFIRE INTERSECTS A FURTHER CONTINUOUS [email protected]/t GOLD IN DRILL RESULTS AT ITS 100% OWNED YIDBY PROJECT
Highlights:
________________________________________________________________
- Yidby Gold system extended in recent drilling program with new results including 20m @ 1.73g/t Gold.
- Drilling confirms continuity of previous high-grade intercepts.
- Metallurgical test work completed earlier in 2024 confirmed both under-reporting of grades due to coarse gold and leachability with excellent recoveries.
- The Company is planning a shallow open-cut heap leach operation.
Australian resource company Surefire Resources NL (ASX: SRN) ("SRN" or the "Company") is pleased to advise the completion of the drilling of new targets at the Company's 100% owned Yidby Gold project in the Mid-West of Western Australia, Figure 1.
The Yidby Gold Project is an emerging large gold system and contains significant mineralised zones up to 80m wide with anomalous gold currently extending over a 3 km strike length. This latest drilling program was aimed at extensions to the current mineralised system plus new priority targets delineated from data reviews of geophysical (gravity and IP) data, structural interpretation and relogging of drill chips (see ASX announcement 17 October 2024).
A total of 13 reverse circulation (RC) drill holes for 1,782m were completed. 1m samples were collected from each hole and then a standard 4m composite was submitted to the laboratory for assay. Drill holes were sampled on a 4m composite basis with a clear strategy to then sample the 1m intervals over any horizon showing gold anomalism, as with the previous successful drill programmes.
The Yidby Gold Project is located in the Mid-West region of Western Australia, on the Great Northern Highway, 320km northeast of Perth and 265km east-southeast of Geraldton. It is comprised of four granted exploration licences totalling 130km². The project is a 'blind deposit' discovered by Surefire beneath transported cover by up to 20metres. A feature of Yidby Gold mineralisation is broad mineralised zones with localised spectacular intersections up to 80.5 g/t Gold (YBRC019). The Project is surrounded by several multimillion-ounce gold deposits.
- The 3.24 million-ounce Mount Gibson Gold Project is 30 km to the south of Yidby;
- The 1.1 million-ounce Minjar Gold project approximately 65 km to the northwest; and
- The 1 million-ounce Kirkalocka Gold Project approximately 70 km to the northeast

Table 1: Details for YBRC102 and YBRC103.
Figure 1: Location map of the Yidby Gold project.
These results follow previous gold results in the area (refer ASX announcement 1 June 2023), with a gold horizon occurring in the saprolite at shallow depths of less than 1ppm before higher grades are intersected beneath this in fresh rock, predominantly a quartz-porphyry (see figures 4 and 5). The 1m samples have been retrieved for submission to the laboratory for gold assay.

Hole YBRC 102 intersected 20m @ 1.73g/t Au from 80 to 100m in depth. Figure 3, above, shows the chip sample tray with the drilling intersection. The drilling chips highlight a mafic/ quartz felsic porphyry contact zone with a wide peripheral alteration zone into both lithologies displaying Quartz + common sulphides (pyrite) up to 2%.

Geology
The Quartz Felsic Porphyry (QFP) occurs throughout the Yidby Gold Project as a continuous and lensoidal lithology, locally to 30m in true width, up to 500m in strike, and open for extension at both ends. This lensoidal lithology commonly contains gold mineralisation.
Peripheral to the QFP is located a resilient hard mafic assemblage. It has been inconsistently logged surrounding the Quartz Felsic Porphyry (QFP) at Yidby as a mafic basalt or as a resilient ultramafic.
Surefire now interprets the peripheral lithology to be a metamorphically, chemical and temperature, altered ultramafic; a Meta-Ultramafic. The temperature and chemical alteration change the ultramafic from ductile to more brittle. When influenced by a later stage shear or fault, the now brittle metaultramafic rock fractures to provide more favourable permeability, better channel conduits for gold bearing fluids, resulting in increased potential for gold mineralisation. This latest drilling appears to confirm this model for gold mineralisation see Figures 4 and 5.

Exceptional Metallurgical Gold Recovery
Metallurgical column leach test work on Yidby Gold carried out by Surefire has provided fantastic results with the initial sighter test work completed in 2022 providing excellent gold recovery up to 99.5% (ASX Release 11/11/2022) and an exhaustive, coarse (6.8mm crush), non agglomerated column leach test program January 2024 (ASX Release 18/3/2024) providing 66.3% gold recovery and a 68% increase in gold content. Surefire now understands the presence of fine (<0.5mm) coarse gold acts to underestimate the drill hole sample assay reading. The drilling assays for the column leach test provided a 0.75g/t Au initial grade. At the conclusion of column leaching 1.26g/t Au was recovered, an increase in gold of 68%(refer ASX announcement 18 March 2024).
The Company plans further work to develop an open cut heap leach operation.
Next steps
Remaining assays results are expected over the coming weeks and will be reported once received.
Management Comment:
Mr Paul Burton, Managing Director said "The results from the 4m composites are encouraging and continue to show mineralisation extending beyond our previous intersects. The 1m are now being assayed with results expected in the coming weeks. The project has clear mineralising trends now evident which provide targets for future drilling as the project evolves into what the company plans as a low-cost heap leach operation".
