Caravel Minerals has advanced its Caravel Copper Project DFS with a 48% increase in Proven Ore Reserves and secured $15 million in new royalty funding from Regal Royalty Fund, while extending key regulatory timelines.
- Updated Ore Reserve totals 597Mt at 0.24% copper
- Proven Ore Reserves up 48% since 2022 maiden estimate
- DFS extended to September 2026 for groundwater studies
- Hybrid power plan combines grid and solar-battery supply
- Received $15M royalty funding; loan maturity extended to 2028
Ore Reserve Upgrade Strengthens Project Confidence
Caravel Minerals (ASX:CVV) has lifted the confidence in its Caravel Copper Project with an updated Ore Reserve of 597 million tonnes grading 0.24% copper, containing 1.42 million tonnes of copper. The standout figure is a 48% increase in Proven Ore Reserves to 156 million tonnes at 0.25% copper, reflecting improved geological confidence from recent resource updates and detailed mining studies. While the total contained copper remains broadly unchanged from the 2022 maiden reserve, the upgrade marks a significant step in de-risking the project’s resource base.
The Ore Reserve update also introduces, for the first time, reporting of molybdenum, silver, gold, iron, and sulphur grades within the reserve, offering a more comprehensive view of the deposit’s value potential. This classification upgrade underpins the staged mining approach focused initially on the Bindi deposit, with the Dasher deposit scheduled for later development to optimise capital deployment and operational efficiency.
DFS Progress and Regulatory Milestones
The Definitive Feasibility Study (DFS) timeline has been extended by three months to September 2026 to accommodate additional groundwater bore installations and updates to the Environmental Review Document (ERD). These steps are critical to securing water licensing, a key regulatory hurdle given the project’s 25-plus year mine life. Importantly, Caravel maintains its target for Ministerial consent and final investment decision by the end of 2027, signalling confidence that the delay will not cascade into the broader approval schedule.
Environmental baseline monitoring is underway, supporting a robust environmental impact assessment. The company’s deliberate engagement with the Department of Water and Environmental Regulation aims to smooth the ERD submission and subsequent public comment period, enhancing the prospects of a streamlined EPA assessment.
Innovative Hybrid Power Strategy
Power supply planning has advanced with Caravel securing a draft Access Offer from Western Power for up to 89MW grid capacity in winter and 72MW in summer. To meet the project’s peak demand of approximately 125MW, the company will supplement grid power with a behind-the-meter solar-battery facility comprising 170MW solar PV, 100MW/400MWh battery storage, and a 44MW diesel backup. This hybrid approach aims to deliver reliable, low-cost energy, support future fleet electrification, and reduce execution risk.
Royalty Funding and Financing Update
Caravel received $15 million from Regal Royalty Fund for a new 0.75% net smelter return royalty, doubling Regal’s total investment in the project to $30 million. Concurrently, the maturity of an existing $15 million loan facility from Regal was extended to 31 March 2028, providing financial flexibility as the DFS advances. These funding arrangements bolster Caravel’s capital position without immediate equity dilution, complementing ongoing discussions with potential precious metal streamers and offtake partners including Adani.
Engineering and Infrastructure Developments
Engineering design work is progressing, with process plant flowsheets finalised and water demand estimates reduced from 18 to 12 gigalitres per year. Tailings management, site layout, and infrastructure designs are advancing to DFS standards, supported by independent peer reviews and value engineering exercises. Logistics and shipping studies have commenced, with early engagement of port operators in Bunbury and Geraldton.
Mining studies confirm a conventional open pit operation using ultra-class haul trucks and shovels, with plans to transition early to autonomous haulage. Initial mining is expected to be contractor-operated to de-risk start-up, moving to owner mining later in the project’s life.
Drilling programs have supported geotechnical data collection and environmental monitoring, including exploration of a new brackish aquifer as a contingency water source, which could provide a low-risk, net positive environmental outcome by alleviating rising water tables and surface salinisation.
Bottom Line?
Caravel’s enhanced Ore Reserve and hybrid power strategy underpin a maturing copper project, but the extended DFS timeline and pending groundwater studies remain key milestones to watch.
Questions in the middle?
- How will the final groundwater studies influence the timing and scope of water licensing?
- What impact will the hybrid power solution have on operating costs and emissions over the mine life?
- When will offtake and precious metals streaming agreements be finalised to support project financing?
