Balkan Mining and Minerals
Overview
The recent boom in electric vehicle (EV) adoption and green technologies has seen global demand for lithium skyrocket. Analysts believe EV penetration could reach 35% by 2030, which means lithium production will need to quadruple between 2020 and 2030 to satisfy this growing demand.
Lithium production is often associated with countries like Chile, Australia and Argentina — but strategic policy shifts in the European Union have led Europe to look inward for essential battery metals, placing the spotlight directly on the Balkan states. While the Balkan states, which includes Albania, Bosnia and Herzegovina, Bulgaria, Croatia, Kosovo, Montenegro, North Macedonia, Romania, Serbia and Slovenia, are best known for historic gold production — recent lithium discoveries in Serbia have renewed interest in this region.
Balkan Mining and Minerals (ASX:BMM) is focused on an early-stage exploration through the full development of lithium and boron mining in the Balkan region. The company is committed to building an ethical resource portfolio backed by strategic partnerships and guided by an experienced board and management with regional expertise.
The Balkan states, and Serbia in particular, are well-endowed with many minerals and have attracted a surge in foreign investors for the exploration of mining operations. Serbia's Vardar zone is an emerging tier 1 lithium-borate jurisdiction. Balkan Mining and Minerals is well-positioned to capture the growth of the European lithium and boron supply chain.
Balkan Mining and Minerals' flagship Rekovac lithium-borate project demonstrated two successful diamond drill holes discovering preserved lithium and borate mineralization. The company recently completed its surface mapping program. With the success of the initial drilling and exploration, Balkan is well-positioned to commence its drill program in late September 2021.
The company continues to expand its reach across Serbia with four new exploration permits recently granted. The Ursule and Siokovac licenses provide expansion of Rekovac and span nearly 200 square kilometers. The Dobrinja and Pranjani licenses provide access to Western Serbia with favorable lacustrine strata for hosting lithium and boron.
"It's the right region, it's the right commodity and the right capital structure with the right investors… the key thing to add to that is what differentiates this particular lithium project from many of the other … lithium companies, at least listed in Australia, is the borate angle… So that makes these types of things extremely economic and extremely easy to mine and process," commented Ross Cotton, managing director.
Balkan Mining and Minerals is backed by Sandfire Resources (ASX:SFR). The company's current market cap is AU$36 million with 45 million shares on issue.
The leadership of Balkan Mining and Minerals includes a highly commercial board with decades of experience. Sean Murray serves as chairman and brings executive experience from Rio Tinto and expertise in industrial minerals. General Manager Dejan Jovanovic is the Balkan region expert with over 15 years of experience as a geologist. The company has a strong combination of experience and expertise to be a leader in the lithium and boron space.

- The company is backed by leaders in the space and has performed well since its IPO. An experienced board and regional management expertise equip Balkan Mining and Mineral to be a leader in the lithium-borate space and are in the right space at the right time.
Key Projects
Rekovac Lithium-Borate Project
The flagship Rekovac lithium-borate project is located in the world-class Vardar Zone in Serbia, an emerging tier 1 lithium-borate jurisdiction. The project has easy access to the motorway and modern rail corridor, thus providing a solid infrastructure to Central and Western Europe.
The first two diamond drill holes (1,238 meters) revealed preserved lithium and borate mineralization at both sites. The second drill hole (REK-002) intercepted over 171 meters with over 10,000 ppm of B2O3 and up to 969 ppm Li2O from 35 meters including 49.6 meters with over 20,000 ppm of B2O3 and up to 624 ppm Li2O from 51.5 meters.
The success of the initial drilling and exploration has provided a solid foundation to explore additional areas of Rekovac as well as two additional adjacent areas under the Ursule and Siokovac licenses. The recently completed surface mapping of the entire Rekovac area has identified five dominating sedimentary formations. The samples will be sent to a laboratory for mineral phase determination using the X-ray diffraction method.
Balkan Mining and Minerals plans to measure magnetic properties over the entire diamond drill core. In addition to measuring magnetic susceptibility, the company will measure the bulk density of samples selected from the drill core. These two parameters will guide geophysics surveys across high-priority areas and ultimately define and commence new drilling programs.
Cacak Project
The Cacak project comprises the Dobrinja and Pranjani license and is located in Western Serbia about 90 kilometers south-southwest of Belgrade, the capital of Serbia. A database study conducted by the Yugoslav Geological Survey identified favorable lacustrine strata for hosting lithium and boron.
The project is in its early exploration phase and will focus on target generation using regional geophysics, geological mapping, and surface sampling. Upon completion of the initial assessment, drill testing of the target locations will be conducted. The licensed areas are within the Vardar Zone and present the company with another location for extracting lithium and boron minerals.

DLE Pilot Plant First Stage Production Completed, Downstream Process Optimised with Sample of Battery-Grade Lithium Produced
Highlights:
- An initial volume of 88m3 of concentrated eluate, which is the lithium carbonate equivalent (LCE) of approx. one tonne, has been produced from the Company´s DLE pilot plant in Copiapó, Chile over an operating period of 384 hours with 14 cycles completed
- This completes the first stage of production from the DLE pilot plant
- Results show the DLE adsorbent achieved a lithium recovery rate of approximately 95% from the brine, with total recovery (adsorption plus desorption) achieving approximately 88%
- Impurity rejection rates were very high producing a low impurity eluate conducive to the downstream conversion process.
- The concentrated eluate is being shipped in four batches to the facilities of Conductive Energy in Chicago, USA, for conversion into battery grade lithium carbonate
Shipment | Eluate Volume | Eluate Li Grade | LCE (kg) | Shipment Status |
1 | 24m3 | 2008 mg/L | 257 | Arrived process facility |
2 | 24m3 | 2360 mg/L | 301 | In Shipment |
3 | 24m3 | 2325 mg/L | 297 | In shipment |
4 | 17.5m3 | 2464 mg/L | 230 | At departure port |
Targeted | 90m3 | 2000 mg/L | 1022 | |
Total Achieved | 88m3 | 2289 mg/L | 1085 |
Table 1: Status of concentrated eluate from pilot plant first stage production
- Conductive Energy completed test-work on a 200L sample of concentrated eluate shipped in May 2024 to optimise the downstream process before receiving the larger volume shipments
- The conversion test-work produced multiple samples of lithium carbonate with 99.75% lithium carbonate purity demonstrating that the process achieves targets and is repeatable
- The result is a first confirmation that a process has been developed that will efficiently produce battery-grade lithium for the Laguna Verde project from pilot scale DLE eluate
- CleanTech Lithium continues to be a leader in exploration and development of DLE based projects in Chile and this pilot scale production will provide large test samples of lithium carbonate to potential offtake partners seeking product qualification.
- Subject to the completion of the re-injection well in September, the reserve report for Laguna Verde is scheduled to be completed by Montgomery and Associates in October 2024.
Steve Kesler, Executive Chairman and Interim CEO, of CleanTech Lithium PLC, said:
"We are very pleased by these results as it shows we can produce battery-grade lithium with low impurities from our Laguna Verde brine project. Working with our partners on the downstream process, Forward Water and Conductive Energy, we can now demonstrate the entire DLE process from brine to final lithium product.
"The optimised downstream process will now be applied to the initial volume of 88m3 of concentrated eluate, or approximately 1 tonne of LCE, produced from the first stage of production from our DLE pilot plant. This will produce significant test sample volumes of battery-grade lithium carbonate for commencement of testing with potential strategic partners. This is important whilst the Chilean government is reviewing the feasibility of lithium projects to identify the most advanced companies in Chile and if they are to reach their target of having three to four new lithium projects in development by 2026."
Further Information
Pilot Plant in Copiapó First Stage Production Completed
The Company´s DLE pilot plant is in Copiapó, Chile, approximately 275km from Laguna Verde. The plant finished commissioning in late March 2024 and up until mid-June a total volume of 1196m3 of brine from the Laguna Verde project was processed in the plant with a total of 14 cycles completed. Each cycle represents a volume of brine being fed first through filtration to remove suspended solids, then into DLE columns which are filled with adsorbent designed to be selective for lithium molecules. Lithium, as lithium chloride, is adsorbed from the brine, before desorption with water to create a purified lithium chloride eluate. A reverse osmosis (RO) unit at the DLE pilot plant then concentrates the eluate by extracting approximately 75% of the water to form a concentrated eluate.
Averaged across the 14 cycles, the recovery rate achieved by adsorption of lithium by the adsorbent was 95% and the recovery rate of desorption from the adsorbent was 93%. The total recovery rate averaged 88% and was highly consistent as shown in Figure 1. The temperature of the brine and desorption water, using the average ambient temperature in Copiapó during the March to June period of operation, was in the range of 20oC to 25oC, which did not significantly affect the recovery achieved.
Figure 1: Pilot Plant Total Recovery Rate
The eluate production rate was relatively stable after the initial ramp up period achieving an average of 2.8 kg LCE per hour. The design of the plant is 1 tonne per month of LCE based on designed monthly operating schedule of 360 hours. Due to budget and volume considerations, the plant was run for 384 hours for the first stage of planned operation producing a total of 1.085 tonnes of LCE as eluate. Based on the hourly production rate this met and exceeded the design capacity of the plant.
Figure 2: Pilot Plant Production Rate (Kg LCE/hr in Eluate)
Selectivity of the adsorbent is another key performance parameter for a DLE operation. DLE primarily acts as a purification stage, recovering lithium chloride from the brine whilst rejecting other impurities. For all the major ions in the brine, apart from boron, the rejection rate was very high as shown in Fig. 3 below. More cycles will further validate this performance. The quality of the eluate was consistent over the first stage of production with the low level of impurities facilitating downstream conversion.
Figure 3: DLE Performance - Rejection of Major Impurities
After completion of the DLE stage, the eluate is concentrated using a reverse osmosis (RO) unit at the pilot plant. On completion of both stages the lithium grade in the purified lithium chloride eluate is over ten times higher than the feed brine. The concentrated eluate was then loaded into a flexitank in a standard shipping container and transported to the port of Caldera for shipment to North America.
Downstream Processing into Battery Grade LithiumCarbonate: Test-work Completed
For the conversion of the concentrated lithium chloride eluate into battery grade lithium carbonate, CleanTech Lithium has engaged a leading lithium processing company, Conductive Energy, based in Alberta, Canada, which has facilities in Chicago, USA, with key downstream processing units shown in Figure 4 below. The status of the concentrated eluate shipment is shown in Table 1 with processing to commence in August 2024.

Figure 4: Conductive Energy Carbonation Reactor Tank and Equipment for Washing, Filtering & Drying
In May 2024 CTL air-freighted a 200L sample of concentrated eluate from the pilot plant to Conductive Energy to undertake test-work to optimise the conversion process. The process steps are shown in Figure 5, involving a further stage of RO, before using Forward Osmosis (FO) to achieve a very high level of concentration. Ion exchange (IX) is used to remove calcium, magnesium, and boron. The final steps are carbonation and then washing, filtration and drying to produce a battery grade product. Conductive Energy´s approach is to simplify the process that achieves maximum yield by minimizing process steps and, where losses occur, produce fluids that are easily recycled to further maximize yield.
Figure 5: Conductive Energy Conversion Process
Reverse Osmosis and Forward Osmosis
The increase in eluate and lithium concentration in the R/O and F/O stages are shown in Table 2 below. R/O is effective for concentration until Total Dissolved Solids (TDS) reach the level of approximately 60,000 - 70,000 TDS, after which it is increasingly energy intensive and costly. F/O is highly effective in further concentration to the required lithium grade for carbonation, in this case 18,000mg Li/L (or 1.8% Lithium). The F/O unit is provided by Forward Water Technology, another Canadian company based in Ontario. F/O achieves a high concentration factor with much lower energy use than the alternative of using a mechanical evaporator, while being highly suitable for utilising solar thermal as the energy source to power the F/O process.
Parameter | Unit | Concentrated Eluate | R/O Concentrate | F/O Concentrate |
Lithium (Li) | mg/L | 2,194 | 5,700 | 18,000 |
Chloride (Cl) | mg/L | 11,039 | 37,000 | 110,000 |
Boron (B) | mg/L | 411 | 850 | 1,700 |
Calcium (Ca) | mg/L | 7 | 29 | 85 |
Magnesium (Mg) | mg/L | 14 | 50 | 150 |

Ion Exchange to Remove Impurities
Ion exchange (IX) was used for removal of calcium and magnesium, which achieved 85% and 87% reductions respectively. While feed concentrations were low, 100% of barium and manganese were also removed in the same process. Additional optimization is possible with potential for further calcium removal. Lithium loss was low at 3%.
Conductive then applied its optimised IX for removal of boron. This was highly effective achieving >99.5% removal of boron. However, there was a 22% loss of lithium to the regeneration fluid. This would be recaptured by recycling the regeneration fluid to the F/O feed which was not implemented for this small-scale test-work. The lithium loss from the boron IX is expected to be reduced (recovered) to a steady state loss rate of about 3%.
Carbonation and Battery Grade Lithium Sample
The carbonation test-work achieved an exceptional yield of 96% of the theoretical maximum. The final product, after the wash procedure, was 99.75% lithium carbonate purity as shown in Table 3. Further optimisation of the washing stage is planned in order to reduce impurities to the greatest extent possible and therefore maximise the value of the battery grade product.

Additional Operations
Laguna Verde Reserve Report Update
The next stage of resource evaluation at the Laguna Verde project is to produce an updated JORC compliant resource and a reserve report based on converting a portion of resources into reserves. The management of the resource evaluation programme and reserve report is led by Montgomery and Associates, a leading hydrogeology consultant with extensive experience in resource evaluation of lithium brine projects in Chile and Argentina. Reserve estimation will feed directly into the Pre-Feasibility Study which is targeted for later this year.
The reserve calculation requires the completion of pumping tests and a re-injection well at the project which is scheduled for September 2024, when drilling equipment can be re-mobilised after the current winter break in operations. Subject to the completion of the re-injection well in September, the reserve report is scheduled to be completed by Montgomery and Associates in October 2024.
