Caprice Resources has declared a maiden 522,000-ounce JORC Mineral Resource at its Island Gold Project in Western Australia, including a 340,000-ounce high-grade component. The resource gives the company a quantified platform for growth, but nearly half the ounces remain Inferred and the project is not yet an Ore Reserve.
- 6.16Mt at 2.6g/t gold for 522koz
- 340koz high-grade subset at 5.8g/t
- 48% of contained gold classified as Inferred
- Conceptual Exploration Target of 500koz to 900koz
- Approximately 25,000m remains in current drilling campaign
Maiden resource puts a number on Island Gold
Caprice Resources Ltd (ASX:CRS) has turned its Island Gold exploration story into a 522,000-ounce Mineral Resource, declaring 6.16 million tonnes at 2.6 grams per tonne gold across the 100%-owned project in Western Australia’s Murchison district. It is the first formal resource estimate for the main Central Island area and gives the company a measurable base from which to pursue its stated ambition of growing the project beyond one million ounces.
Central Island accounts for 498koz, or about 95% of the project total, while New Orient contributes 24koz. The estimate contains 269koz classified as Indicated and 253koz classified as Inferred, meaning 48% of the contained gold carries the lower level of geological confidence. No Measured Resource has been reported.
Vadrians supplies the high-grade centre
The more striking feature is the grade distribution. A subset of 1.8Mt contains 340koz at 5.8g/t gold using a 3.0g/t cut-off, with a further 228koz grading 7.5g/t at a 5.0g/t cut-off. Within the Central Island pit shell, the Vadrians-hosted BIF1A domain contains 252koz at 3.3g/t and represents 87% of the contained gold in that shell.
That result builds on the company’s earlier Vadrians drilling extensions, which extended mineralisation along strike and at depth. Caprice says mineralisation at Vadrians remains open along strike and at depth, while additional drilling around Baxter and Golconda could add to later resource updates. The high-grade core is concentrated in fresh rock: roughly 80% of the gold within the Central Island pit shells sits in fresh material, at 4.3g/t, compared with lower-grade oxide and transitional zones.
Drilling continues beyond the database cut-off
The estimate uses drilling and assays available to 10 August 2026, while the rigs have continued turning. Caprice had about 25,000m remaining from its 50,000m programme as at 15 October, with two rigs targeting resource extensions, infill drilling and new discoveries. The company reported A$9.5 million in cash at 30 September.
The next resource iteration will therefore be shaped by results that were not included in today’s model. Assays are outstanding from 5,376m of drilling in the Gap Zone between Vadrians and New Orient, and the programme is also targeting the broader North and South Island, Western Island and Southern Lake areas.
Exploration Target adds scale, not ounces
Caprice has separately outlined an Exploration Target of 8Mt to 12Mt at 2.0g/t to 2.5g/t for 500koz to 900koz of contained gold. The target covers conceptual extensions along strike and down plunge, as well as underexplored BIF and mafic horizons across the project. It is explicitly separate from the Mineral Resource and cannot be treated as additional inventory: the company says there has not been enough exploration to estimate a resource, and further work may not produce one.
The project also has some metallurgical support. Earlier testwork, including the reported 94% Vadrians recovery testwork, returned recoveries of up to 94% using conventional gravity and carbon-in-leach processing, with the company describing the gold as free-milling. Those results informed the preliminary 95% recovery assumption used in the pit-shell optimisation, rather than representing a completed development study.
Resource confidence remains the central question
The resource is constrained by preliminary pit shells using an assumed gold price of A$5,000 an ounce, a 40-degree pit slope, mining costs of $5.80 a tonne and processing costs of $44.45 a tonne. The shells are reporting constraints only; they are not a mine design, Ore Reserve or economic development study.
Caprice also flags the usual complications of a nuggety gold system, including a 25% to 51% nugget effect, limited precision in higher-grade field duplicates and the absence of an umpire laboratory programme. One blank returned 1.23g/t gold, while an ALS reference material has run about 12% above its certified value since April 2026. New Orient remains entirely Inferred, lacks project-specific density and metallurgical testwork, and includes historical drilling and workings that have not been fully verified.
Bottom Line?
The resource establishes a credible high-grade starting point, but the investment case now depends on whether continued drilling converts conceptual upside and Inferred ounces into a better-defined, economically testable inventory.
Questions in the middle?
- Can the remaining 25,000m of drilling add ounces without materially diluting the 5.8g/t high-grade component?
- How much of the 253koz Inferred Resource can be converted to Indicated through infill drilling?
- Will follow-up density, metallurgy and QAQC work strengthen confidence in the resource model, particularly at New Orient?
