CAV shares surge 12% as Carnavale Resources wraps intensive drilling campaign at Kookynie Gold Project

Carnavale Resources Limited (ASX: CAV), a Western Australian mineral explorer with a market capitalisation of approximately A$57 million, has confirmed the completion of its reverse circulation and diamond drilling programs at the Kookynie Gold Project, a 116,900-ounce gold resource located 60 kilometres south of Leonora and 180 kilometres north of Kalgoorlie. The drilling campaign, which ran for five weeks across three rigs operating around the clock, was specifically designed to support the Bankable Feasibility Study that commenced in December 2025 and remains on schedule for completion by mid-2026. The announcement is a technical milestone rather than a resource upgrade, but its significance lies in what it de-risks: the ability to deliver a construction-ready project in Q3 2026, timed against a gold price environment that has rarely been more favourable to small-cap developers. Carnavale Resources shares responded emphatically, rising 12% on the day to A$0.14, approaching the 52-week high of A$0.15 from a 52-week low of A$0.043.

How does the completed BFS drilling program reduce development risk at Kookynie Gold Project?

The breadth of the completed drilling program reflects a deliberate effort to remove the most common failure modes for junior gold projects attempting to transition from scoping study to construction approval. Six large-diameter diamond drill holes recovered 150 kilograms of core for metallurgical testwork, providing the physical sample mass required to characterise gold recoveries across oxide, fresh, and transitional ore at the Swiftsure and Tiptoe pits. Eight geotechnical diamond holes were drilled around the proposed pit walls and ramps to deliver structural and rock quality data that will inform final pit designs and slope stability assessments. Critically, there is potential to steepen pit wall angles based on this analysis, which would reduce the strip ratio and improve project economics without requiring additional resource definition.

The most commercially significant component, however, is the infill reverse circulation drilling on a 10 metre by 10 metre pattern across approximately 8,500 metres of the Swiftsure and Tiptoe open pit footprints. This high-density grid drilling is specifically aimed at upgrading Indicated mineral resources to the Measured classification, the highest confidence category under the JORC Code and the threshold typically required by project financiers and toll treatment operators before committing to binding commercial terms. The current resource stands at 842,300 tonnes at 4.3 grams per tonne gold for 116,900 ounces, with no Measured component and 77,200 ounces sitting in the Indicated category. The RC assay results are expected within approximately four weeks.

What does the toll treatment strategy mean for Kookynie’s capital requirements and path to production?

Carnavale Resources has consistently positioned the Kookynie Gold Project as a toll-milling opportunity rather than a standalone processing build, and the current metallurgical testwork program is structured around that commercial model. The metallurgical work, being executed with samples from the large-diameter diamond holes and supplemented by the infill RC material, is focused on establishing gold recoveries and processing characteristics specifically relevant to toll treatment, including crushing and grinding behaviour and gravity separation properties. These parameters are what prospective toll processors need to price treatment agreements.

The logic of this approach is straightforward for a junior developer. Western Australia’s Eastern Goldfields region has significant existing mill capacity at operating mines, several within trucking distance of Kookynie. By avoiding a standalone processing plant, Carnavale Resources can potentially reduce upfront capital requirements substantially and compress the timeline from feasibility approval to first gold. Sixty rock samples have also been dispatched to SRK for waste rock characterisation, which feeds into environmental approvals for waste dump designs. That parallel workstream matters because environmental approvals are frequently the longest lead-time item in Australian mine permitting.

Why is the geotechnical data from Kookynie’s proposed pit walls strategically important for project economics?

Geotechnical uncertainty is a recurring source of cost blowout in open pit gold mining, particularly where initial scoping studies apply conservative slope angle assumptions to manage risk. The geotechnical core recovered from the eight diamond holes drilled around the Swiftsure and Tiptoe pit walls has been shipped to Kalgoorlie for review by independent consultants. If that analysis supports steeper wall angles than those assumed in the October 2025 scoping study, which reportedly doubled the project’s assessed value, the consequences for economics are material. A reduced strip ratio means less waste movement per ounce of ore recovered, directly improving both capital efficiency and operating cost per ounce. The Bankable Feasibility Study will incorporate this data into its mine design optimisation, which Cube Consulting is leading alongside resource and mine planning responsibilities.

How does the Kookynie hydrogeology program affect the BFS timeline and mine permitting approvals?

Hydrogeology is the final major workstream now entering its active phase. A LIDAR survey was completed in December 2025 to establish accurate surface topography for groundwater flow modelling. Production water bores and associated monitoring bores are scheduled to commence drilling during March 2026, entirely within the granted mining lease, which removes a potential regulatory complication. The data from these bores will inform the water balance calculations and dewatering plan that form a mandatory component of the BFS and the subsequent Native Vegetation Clearing Permit and Mining Proposal applications flagged in the BFS study schedule.

Carnavale Resources has presented a clear Gantt chart through to July 2026 showing the sequencing of grade control, geotechnical, hydrogeology, metallurgical, mining engineering, process options, and approvals preparation workstreams. The current position, with drilling complete and assays four weeks away, aligns closely with that schedule. The feasibility report itself is shown commencing in May 2026, with approvals preparation running concurrently. For a company of this size, executing a multi-disciplinary feasibility program with this degree of parallel workstreaming represents a notable operational undertaking.

What does Carnavale Resources’ market re-rating signal about investor sentiment toward small-cap Australian gold developers?

The 12% price move on the announcement date, lifting Carnavale Resources to A$0.14 from a previous close of A$0.125, is noteworthy for a drilling completion release that contains no new assay data. It reflects two things. First, the market is pricing execution confidence: the absence of delays in a program of this scope is genuinely positive signal in a sector where junior developers routinely miss milestones. Second, the broader gold price environment is providing a favourable backdrop for the re-rating of small-cap Australian gold developers. With CAV now trading within 7% of its 52-week high of A$0.15, and having recovered more than 220% from its 52-week low of A$0.043, the stock has already captured substantial re-rating momentum. The next meaningful catalyst is the RC assay package expected in approximately four weeks. If those results confirm the anticipated resource classification upgrade from Indicated to Measured, the project financing narrative shifts materially.

The toll treatment discussions shown in the BFS schedule for May and June 2026 are the commercial inflection point to watch. Measured resource classification combined with favourable metallurgical testwork outcomes should give Carnavale Resources a credible basis to negotiate term sheets with regional mill operators. Without those commercial terms, the BFS remains a technical document. With them, it becomes a financing instrument.

What are the key strategic and financial takeaways from Carnavale Resources’ Kookynie BFS drilling completion?

• The completion of all RC and diamond drilling on schedule keeps the mid-2026 BFS delivery target intact and reduces the most significant remaining execution risk for the Kookynie Gold Project.
• Infill RC drilling on a 10 metre by 10 metre grid pattern is designed to upgrade the existing 77,200-ounce Indicated resource to Measured classification, the threshold that project financiers and toll treatment operators typically require before committing to binding terms.
• Assay results from the infill RC program are expected within four weeks and represent the next material price catalyst for Carnavale Resources (ASX: CAV).
• The metallurgical testwork program is structured specifically around toll treatment parameters, not standalone processing, which limits upfront capital requirements and accelerates the potential path to first gold.
• Geotechnical analysis of pit wall core could support steeper slope angles at Swiftsure and Tiptoe, which would reduce the strip ratio and improve project economics beyond the scoping study assumptions.
• Waste rock characterisation work with SRK is advancing in parallel to support environmental approval applications, addressing a typically long-lead permitting item.
• Cube Consulting’s involvement across resource estimation, mine planning, and the Definitive Feasibility Study provides continuity of technical oversight and reduces the risk of data translation errors between workstreams.
• Toll treatment discussions with regional mill operators are scheduled for May through June 2026, concurrent with finalisation of the feasibility report. The commercial terms secured in that window will determine whether the BFS is a bankable document or a staging exercise.
• At A$0.14 and a market capitalisation of approximately A$57 million, Carnavale Resources is trading near its 52-week high following the announcement, suggesting the market is assigning increasing credibility to the Q3 2026 production-ready project timeline.
• The Swiftsure and Tiptoe orebodies remain open at depth and along strike, and Carnavale Resources has indicated further exploration is being planned within the tenement package, providing optionality beyond the current feasibility scope.
