High-Grade Gold at Sybil Spurs Drilling; Will Results Meet Expectations?

Diamond Drilling Set to Unlock Sybil's Potential

Sunshine Metals Limited (ASX – SHN) has announced the imminent start of diamond drilling at its Sybil epithermal gold project, located approximately 135km west of Townsville, Queensland. This milestone follows a rigorous phase of field validation, including the re-establishment of water infrastructure and clearing of historic access tracks, enabling the company to commence drilling by the end of August 2025.

The Sybil project, part of the broader Ravenswood Consolidated Project, has yielded encouraging high-grade gold results from surface rock chip sampling. Notably, assays from the undrilled Francis Creek East prospect returned grades as high as 28.1 grams per tonne (g/t) gold, while Francis Creek itself produced multiple samples exceeding 10 g/t Au. These results underscore the project's significant exploration upside, particularly given the limited historic drilling coverage.

Strategic Surveying Enhances Drill Targeting

Sunshine Metals has leveraged modern exploration techniques, including a high-resolution drone topographic survey and aerial photography, to refine its geological model and validate historic drill hole collars. This detailed mapping has been instrumental in planning a focused 16-hole diamond drill program, targeting the A and Main Vein systems at Francis Creek. The program is designed to test shallow mineralisation zones that have historically shown promising gold grades but remain underexplored.

Managing Director Dr Damien Keys expressed optimism about the project’s trajectory, highlighting the team's efforts to bring Sybil closer to drill readiness and the excitement generated by new prospects. The company’s approach reflects a blend of leveraging historic data and applying contemporary exploration methods to unlock value in a district with a rich gold mining heritage.

Geological Context and Regional Analogues

Sybil is situated on a large extensional structure characterized by Permian-Carboniferous volcanic rocks, hosting a low-sulphidation, high-grade epithermal gold system. The project shares many geological similarities with the nearby Pajingo gold deposit, which has produced approximately 4 million ounces of gold since 1986. Both systems feature crustiform and colloform quartz-adularia veins, indicative of robust epithermal mineralisation.

Despite its promising geology, Sybil has seen minimal modern exploration over the past two decades, positioning Sunshine Metals to capitalize on its underexplored status. The company’s ongoing fieldwork extends beyond Francis Creek to other prospects such as Blue Range and Burdekin Veins, where initial sampling has also returned encouraging gold grades.

Looking Ahead – Milestones and Market Implications

Sunshine Metals has outlined a busy schedule through early 2026, including the release of metallurgy results, resource upgrades, and further geophysical surveys. The upcoming Resources Rising Stars Conference in September 2025 will provide a platform to showcase progress and attract investor interest.

The planned drilling results from Sybil will be closely watched by the market, as they will provide critical insights into the project's scale and grade continuity. Given the project's analogies to Pajingo and the high-grade surface assays, there is cautious optimism about the potential for resource growth and value creation.
