Australia’s Strickland Metals is advancing plans for a potential first-stage gold operation at its Rogozna project in southwestern Serbia, evaluating a processing facility capable of treating 2.5 million tonnes of ore annually and supporting conceptual gold production of up to 150,000 ounces, or approximately 4.7 tonnes, per year.
The proposed initial development would centre on the Gradina deposit, which contains an estimated 20 million tonnes grading 2.8 grams of gold per tonne, equivalent to approximately 1.8 million ounces of contained gold. The production target remains conceptual and is not supported by a defined mineral reserve or an approved mine plan. Strickland is moving towards more detailed technical assessment to determine whether Gradina can support a commercially viable first operation within the wider Rogozna mineral system.
Additional drilling to support mine design
Strickland estimates that approximately 50,000 metres of additional drilling will be needed to expand Gradina and upgrade portions of its mineral resource into higher-confidence categories. The results will inform detailed engineering and the development of a mine plan.
The work represents a shift in the project’s development priorities, with greater emphasis on mine design, processing requirements, infrastructure and project economics alongside continued resource definition. The transition will require assessment of capital expenditure, operating costs, metallurgical recovery rates, mine access and processing capacity. Gradina’s gold-focused mineralisation could offer a more straightforward starting point than the more polymetallic parts of Rogozna, although detailed metallurgical testing and engineering remain necessary to establish achievable recoveries and processing costs. A plant processing 2.5 million tonnes of ore per year would also require assessment of electricity demand, water supply, tailings management, underground development and waste handling.
Rogozna resource supports a staged development strategy
The wider Rogozna project contains approximately 9.25 million ounces of gold equivalent across several deposits, including Gradina, Shanac, Copper Canyon and Medenovac. This resource base provides Strickland with the option of pursuing an integrated development covering multiple deposits or advancing individual deposits in stages. The current concept places Gradina at the centre of the initial production phase.
An operation targeting around 150,000 ounces of gold annually would establish a producing asset on a smaller initial scale than a development designed around the broader mineral system from the outset. A staged approach could enable Strickland to establish processing facilities, electricity connections, roads, water systems and operational capacity before considering subsequent expansions. It could also limit the initial financing requirement compared with developing the wider district in a single phase. The commercial viability of Gradina as a standalone operation remains the immediate development question.
Copper potential remains relevant to later phases
Copper Canyon and other parts of Rogozna contain more substantial base-metal mineralisation, providing potential for the project to expand beyond gold if subsequent deposits demonstrate economic viability. The broader mineral system could therefore support a longer-term gold and copper development, with a first mine at Gradina potentially providing the operational foundation for further development. Realising that potential would depend on the economics of the additional deposits and the feasibility of incorporating them into later development stages.
Technical studies to determine capital requirements
Strickland has strengthened its balance sheet to fund drilling and technical studies, providing financial capacity to advance the project without immediately relying on mine-construction financing. A move into construction would require a substantially larger capital commitment. The overall investment requirement has not yet been established, pending further engineering work on plant configuration, underground development, infrastructure and environmental requirements.
The forthcoming studies will therefore need to establish the project’s expected cash flows, operating costs, capital intensity and execution risks. These factors will be central to assessments by prospective lenders and strategic partners, alongside the scale of the mineral resource.
Rogozna expands Serbia’s mining development pipeline
Rogozna adds to Serbia’s portfolio of mining projects and operating assets, which includes DPM Metals’ Čoka Rakita project, Zijin’s expanding operations in Bor and several international exploration programmes. Located in southwestern Serbia, Rogozna would also broaden the geographical distribution of mining investment beyond the country’s established copper and gold production centre in the east. The next development milestone is the conversion of the Gradina concept into a technically and financially credible mine plan. If the proposed initial phase proves viable, the target of 150,000 ounces of annual gold production could form the starting point for the wider Rogozna gold and base-metals district.
