Executive Summary
This report presents an updated Mineral Resource Estimate for the Timok Gold Project in Serbia, commissioned by Dundee Precious Metals. The technical report documentation indicates that there are currently no Mineral Reserves defined for the property.
As of the date of this report, the project is not considered an Advanced Property, as there is no current Preliminary Economic Assessment (PEA), prefeasibility study, or feasibility study to support the potential economic viability of the identified Mineral Resources. Consequently, technical details regarding operational throughput, mining methods, and recovery processes are not applicable at this stage of development.

Executive Summary
This Pre-Feasibility Study (PFS) Technical Report outlines the proposed processing methods for the Timok Gold Project, focusing on the recovery of gold and silver from oxide and transitional ore deposits. The project design utilizes conventional heap leach technology with a Heap Leach Fill (HLF) configuration, targeting a throughput of 2.5 million tonnes per annum (Mtpa). The ore is sourced from the Bigar Hill (BH), Korkan (KO), and Korkan West (KW) deposits, with an average gold grade of 1.07 g/t and an overall discounted gold recovery of 82.6% for the combined oxide and transitional ore types.
The processing facility is designed for an 8-year mine life, with the heap leach pad constructed in two phases totaling 19.2 million tonnes of ore. The flowsheet includes a three-stage crushing circuit, an agglomeration circuit for high-clay ores, and a solution recovery system comprising an Adsorption, Desorption, and Recovery (ADR) plant. The ADR plant utilizes Vertical Carbon-In-Column (VCIC) technology to recover gold and silver from the Pregnant Leach Solution (PLS), followed by electrowinning and smelting to produce doré bars.
The report confirms that the metallurgical testwork supports the selected process flowsheet and associated recovery factors. Key design criteria include a crush size of 100% passing 25 mm, a leach cycle time of 90 days, and specific reagent consumption rates for sodium cyanide, cement, and lime. The plant layout ensures constructability, operability, and maintainability, with the QP opinion supporting the project evaluation based on the mineral resource and reserve estimates.

Executive Summary
This report details the Pre-Feasibility Study (PFS) for the Upper Zone of the Timok Copper-Gold Project in Serbia. The recovery methods focus on a single bulk concentrate flowsheet designed to treat sulphide ore containing covellite and enargite. The plant is designed to produce a single bulk concentrate with a capacity of 3,250,000 tonnes per annum.
The process plant design includes primary crushing located underground, followed by an overland conveyor to the mill. The grinding circuit utilizes a SAB (SAG and Ball mill) configuration. Copper recovery is achieved through a flotation circuit comprising rougher, regrind, and two-stage cleaner flotation cells. The concentrate is then thickened and filtered before storage and load out.
Key design criteria include a flotation feed size of 75 µm P80 and operating availability of 92% for grinding and flotation. The plant also includes effluent treatment to manage acidic water from the tailings impoundment. Reagents such as lime, copper collector, and frother are stored and dosed on-site to optimize recovery.

Executive Summary
This Pre-Feasibility Study outlines the recovery methods for the Timok Project in Serbia, focusing on a copper sulphide ore body containing covellite and enargite. The process plant is designed to treat 8,900 tonnes per day of ore, producing a single bulk copper concentrate. The flowsheet was optimized to handle arsenic content variations, though the current design focuses on a simplified bulk concentrate production strategy.
The processing circuit begins with primary crushing located underground using a jaw crusher, followed by overland conveyance to the surface plant. The grinding circuit utilizes a Semi-Autogenous Grinding (SAG) mill in combination with a ball mill operating in closed circuit. Copper recovery is achieved through a flotation circuit comprising rougher, regrind, and two-stage cleaner flotation cells, followed by thickening and pressure filtration of the final concentrate.
