Australia’s Strickland Metals is preparing the first development phase of its Rogozna gold and base-metals project in southern Serbia, examining a mine capable of processing around 2.5 million tonnes of ore annually and producing up to 150,000 ounces of gold a year.
The conceptual production level would equal about 4.7 tonnes of gold annually, potentially making Rogozna one of Serbia’s more significant new precious-metals developments if technical studies, permitting and financing support construction.
Strickland is focusing the first phase on the Gradina deposit, which contains an estimated 20 million tonnes at 2.8 grams of gold per tonne, equivalent to about 1.8 million ounces, or 56 tonnes, of contained gold.
The resource remains in the Inferred category, meaning substantial drilling and engineering work is still required before it can support a final investment decision.
Company management said approximately 50,000 metres of additional drilling would be needed to test extensions and convert part of the resource into higher-confidence categories.
Gradina emerges as first mine
The development strategy marks an important shift for Rogozna.
Until recently, the project was primarily an exploration story built around rapid growth in mineral resources. Strickland is now increasingly separating the asset into potential development stages, with Gradina emerging as the most manageable first mine.
Chairman Anthony McClure told investors at the Mining Forum Americas in Colorado that Strickland was assessing an operation of around 2.5 million tonnes per year, potentially producing as much as 150,000 ounces annually.
The company is advancing technical studies, with a pre-feasibility study targeted during 2027.
Gradina’s metallurgy could strengthen the economics.
Previous test work achieved average gold recoveries of around 90%, with some tests reaching almost 98%, using conventional flotation. Management has also said the current processing concept would not require cyanide.
That could simplify the initial processing circuit compared with more complex polymetallic deposits elsewhere within Rogozna.
Rogozna resource reaches 9.25 million ounces
The wider Rogozna project is substantially larger than Gradina alone.
Strickland currently reports a combined resource of approximately 217 million tonnes grading 1.33 grams per tonne gold-equivalent, containing about 9.25 million ounces of gold-equivalent metal.
That includes approximately 6.07 million ounces of actual gold, alongside copper, silver, lead and zinc.
The resource is distributed across four principal deposits — Shanac, Gradina, Medenovac and Copper Canyon.
Gradina is almost entirely gold-focused, while other deposits contain more significant base-metal components.
Strickland is considering Copper Canyon as a possible later addition to the initial Gradina development. The company is increasingly examining underground rather than open-pit development options there.
The largest long-term asset is Shanac, which contains more than 5 million ounces of gold-equivalent resources and could ultimately require a substantially larger mining operation than Strickland intends to develop independently.
Management has indicated that a future large-scale Shanac development could attract interest from a major mining company.
Zijin builds strategic position
That possibility has gained additional significance because Zijin Mining has accumulated about 7.4% of Strickland Metals.
The Chinese mining group already operates the large Bor copper complex and Čukaru Peki copper-gold mine in eastern Serbia, making it the country’s dominant metallic-minerals producer.
Strickland views Zijin’s investment as strategic validation of Rogozna, although no agreement has been announced giving Zijin development rights or operational control of the project.
For Strickland, Gradina therefore provides a potential route to developing a mine within the financial and operational capacity of a mid-sized company while preserving optionality around the much larger deposits.
Election period slows field activity
The latest development timetable has also become intertwined with Serbia’s political calendar.
McClure said during the Colorado presentation that Serbian authorities had encouraged mining companies to maintain a lower public profile during the current election period.
According to his account, that contributed to reduced field activity, with Strickland expecting drilling to accelerate again following the October 25 parliamentary election.
The statement represents Strickland management’s account of discussions with Serbian authorities; no corresponding public government statement confirming such an instruction has been identified.
The company expects that, in a favourable scenario, drilling could resume in November.
The temporary slowdown comes after Strickland had planned one of its largest drilling programmes at Rogozna, including work aimed at converting resources and supporting development studies.
Strong liquidity reduces immediate financing pressure
Strickland also enters the development phase with a relatively strong balance sheet.
The company reported around A$81 million in cash and liquid investments at the end of March, while management told investors this week that available liquidity remained around A$80 million.
That gives the company capacity to fund drilling and technical studies without immediately returning to equity markets.
The more significant financing challenge would come later.
A mine processing 2.5 million tonnes annually would require substantially greater capital for underground development, processing facilities, tailings and waste systems, electricity connections, roads and other infrastructure.
Those costs have not yet been established publicly and will be one of the central outputs of the coming engineering studies.
Serbia could gain another significant gold mine
Rogozna sits in Serbia’s Tethyan metallogenic belt, which already supports some of southeastern Europe’s largest copper and gold developments.
If Gradina advances successfully through feasibility studies and permitting, the project could add another substantial precious-metals operation to Serbia’s mining industry while broadening production beyond the Bor mining district.
But the next stage will be considerably more demanding than resource growth.
Strickland must convert enough of Gradina’s Inferred resource into higher-confidence categories, establish capital and operating costs, complete environmental and social studies and demonstrate that the project can secure the necessary Serbian permits and financing.
The 150,000-ounce annual production scenario therefore remains a development target rather than a committed mine plan.
Even so, the direction of the project has changed.
Rogozna is no longer being presented solely as a large exploration discovery. Strickland is now trying to demonstrate that Gradina can become the first commercially developable mine within a much larger Serbian mineral system — while leaving the biggest deposits for a second and potentially far more capital-intensive phase.
