#BRES Blencowe Resources PLC – MoU signed for Graphite Beneficiation in Uganda
Blencowe Resources (LSE: BRES.L) has signed a Memorandum of Understanding (“MOU”) with Singaporean graphite sales and marketing specialist Triessence Limited (“Triessence”) and a leading Asian SPG and Anode material producer (“SPG Partner”). This partnership aims to establish Joint Venture (JV) for a graphite beneficiation facility in Uganda producing 99.95% purified graphite for lithium-ion batteries. This venture will set Blencowe apart from competitors focused solely on producing graphite concentrate and provides a life-of-mine offtake partner near the Orom-Cross Project, offering significant additional commercial advantages.
With this JV, Blencowe’s has strategically aligned with two highly experienced Asian graphite specialists to ensure successful delivery.
Highlights:
· JV Formation: Blencowe and Triessence will each hold a 50% stake in in the SPG facility, with the SPG Partner providing operational expertise. Blencowe retains 100% ownership of Orom-Cross.
· Value Addition: Upgrading 96% graphite concentrate to high-value battery ready 99.95% uncoated SPG significantly enhances commercial returns compared to selling concentrate.
· Risk Mitigation: Partnering with graphite industry experts mitigates operational risk.
· Capital Investment: Triessence will fund 50% of capital costs for the SPG facility.
· SPG Offtake Secured: Triessence will purchase all end product, ensuring consistent revenue and premium pricing for some of the first 99.95% SPG produced ex-China.
· Non-China Focus: SPG product ultimately to be sold to OEMs outside China via Triessence, providing strong political, commercial and funding advantages.
· Next steps: Definitive Feasibility Study (DFS) for the SPG facility will be integrated with Orom-Cross DFS for a comprehensive development strategy.
Executive Chairman Cameron Pearce commented:
“Blencowe has long recognised the substantial advantages downstream upgrading of graphite in-country can offer and securing experienced partners who have the expertise to help us deliver successful SPG production was essential. I am delighted to say that this MOU is another significant milestone in enhancing both the value and distinctiveness for our Company.”
“Our JV team will now focus on the SPG facility feasibility study and integrating it with the Orom-Cross DFS, providing a comprehensive solution that adds considerable value. We anticipate minimal additional costs for this study as we are utilising our partners’ existing vast experience for all costings and design work, and no further bulk sample testing or further resource drilling is needed.”
In-Country SPG Strategy
Selling 99.95% uncoated SPG (spheronised purified graphite) unlocks significantly higher returns than small flake 96% concentrate, leveraging the value from additional processing. Providing high-value SPG products into world markets, and particularly products generated outside of China, addresses a significant market gap, especially if China restricts purified graphite exports.
Blencowe’s exclusive sale of Orom-Cross concentrate to the proposed SPG facility ensures a life-of-mine offtake partner, whilst also allowing the Company to benefit by participating in the downstream sale of higher-value 99.95% uncoated SPG products. As one of the only ex-China producers of uncoated SPG this facility will likely command premium prices from OEMs seeking to diversify their SPG supply chains outside of China.
This downstream SPG strategy focuses only on upgrading the lower value small flake concentrate, which is roughly half of Orom-Cross’s output, while the more valuable large flake concentrate will continue to be sold into traditional graphite markets as concentrate. Blencowe recently announced its first MOU for sale of 15,000tpa large flake concentrate.
SPG Joint Venture
A new Ugandan company will be established for the JV to develop the SPG facility.
A feasibility study for the SPG facility, using Orom-Cross concentrate, will be initiated and will leverage the SPG Partner’s experience for costing and design work, with Blencowe handling in-country requirements. With the upgrade of substantial Orom-Cross concentrate to uncoated SPG as part of the 600-tonne bulk sample test process, a key part of the technical DFS has already been completed and paid for. This SPG study will later integrate into the broader Orom-Cross DFS, aligning both projects. Triessence will finance 50% of construction and handle international SPG sales. The SPG Partner, a global leader and one of the largest graphite companies in the world currently producing around 100,000tpa of uncoated SPG, will oversee operations under a management contract.
The SPG facility’s proximity to the Orom-Cross mine considerably reduces logistics costs for Blencowe and access to low-cost Ugandan hydropower supports a premium grade green 99.95% SPG product.
Commercial Advantages
By channelling Orom-Cross small flake concentrate into the nearby JV SPG facility Blencowe bypasses pricing pressures that other graphite peers will face selling their concentrate into competitive Asian markets. This will secure both sales volumes and favourable market pricing for Orom-Cross.
With a 50% stake in the SPG facility, Blencowe will further benefit from selling uncoated 99.95% SPG at a higher ~US$2,000 per tonne compared to ~US$500 per tonne for 96% concentrate. Proximity to the SPG facility will materially lower Orom-Cross current logistics and operating costs, enhancing overall project economics.
This downstream processing strategy, backed by experienced partners, may attract additional funding options from entities who recognise this long-term value opportunity. The U.S. International Development Finance Corporation (DFC) remains the preferred funding partner for Orom-Cross and supports this strategy, as does the Ugandan Government. Both offer valuable backing.

#SVML Sovereign Metals Ltd – Testwork Delivers Superior Quality Graphite
Graphite circuit feed prepared at Sovereign’s existing Lilongwe laboratory facility has produced high quality concentrates in benchtop and pilot-scale flotation and cleaning
· Four independent laboratories all successfully produced high-grade graphite concentrate averaging over 97% Total Graphite Content (TGC) with flotation recoveries exceeding 90%
· Flotation results demonstrated 1.44% TGC run-of-mine Kasiya ore upgrades to more than 55% TGC rougher concentrate without crushing or milling, process steps typically required for producing graphite concentrates from hard-rock deposits; contributing to the unique low cost characteristics of Kasiya’s saprolite hosted graphite
· Graphite concentrates indicate exceptionally low levels of sulphur compared to typical hard-rock graphite peers – a key metric to qualify as active anode material for lithium-ion batteries
· Results are part of ongoing testwork being undertaken as part of the Company’s graphite marketing and active anode qualification strategy, supervised by Dr Surinder Ghag
· Downstream testwork to produce and characterise Coated Spherical Purified Graphite (CSPG) active anode material continues at German graphite consultancy ProGraphite GmbH
Sovereign Metals Limited (ASX:SVM; AIM:SVML) (the Company or Sovereign) is pleased to announce the results of graphite testwork completed at multiple independent laboratories in Australia, Canada and South Africa.
Graphite flotation and cleaning testwork was conducted on graphite circuit feed from Sovereign’s Kasiya Rutile-Graphite Project (Kasiya or Project) at four different laboratories, which all successfully produced high-grade graphite concentrate (94.9%-97.8% TGC) at high flotation recoveries (91.2%-97.2%).
The testwork demonstrated excellent results using a conventional flowsheet that was consistent across all laboratories, thus confirming Sovereign’s ability to produce a high quality graphite concentrate.
Managing Director Frank Eagar commented: “Our ability to upgrade Kasiya ore at 1.4% graphite to a 55% rougher concentrate without any crushing or milling, highlights more of the unique qualities of Kasiya. There are very limited other graphite projects with these characteristics. The pilot-scale results also confirm that Kasiya produces high-grade concentrates with very low sulphur levels at high recoveries. Simply put, Kasiya will be a standout producer of high-quality graphite concentrate at industry low operating costs.”

The graphite circuit feed provided to the various laboratories was produced at the Company’s existing laboratory facility in Lilongwe, Malawi, where it was screened and separated over a wet shaking table.
Figure 1: Holman Wilfley 2000 wet shaking table in action demonstrating clear separation between Rutile HM, waste and Graphite
The graphite feed grades of 3.5%-4.0% TGC to the graphite circuit are significantly higher than the Mineral Resource Grade of 1.44%, highlighting the ~2.4-2.8-fold upgrading of graphite grades when ROM ore passes through the front-end rutile gravity separation circuit.
This demonstrates the ease of separating the rutile heavy mineral and graphite streams from the front end of the Kasiya Pre-feasibility Study process flowsheet. Subsequently, the two product streams pass into distinct, industry-standard, final product flowsheets. This further highlights the commercial benefits of having both rutile and graphite mineralisation co-existent in the same soft saprolite-hosted orebody.
The first stage of upgrading the graphite feed, rougher flotation, achieved very high rejection (>90%) of waste materials to rougher tails, producing a rougher concentrate with more than 55% TGC and very high recoveries (94%-98%) in laboratory scale testing consistently across all four laboratories. Upgrading the graphite feed at very high recoveries and rejection of non-graphitic minerals without run-of-mine milling is another of Kasiya’s significant advantages, supporting the lowest cost graphite production.
The rougher concentrate was further upgraded through laboratory scale flotation, cleaning and polishing stages, producing high-grade concentrates at high graphite circuit recoveries.

Pilot-scale testwork confirmed the laboratory-scale results with >90% TGC recovery to high-grade graphite concentrates (<180-micron concentrate at 96.9% TGC and >180-micron concentrate at 97.2% TGC).

HIGHLY FAVOURABLE IMPURITY PROFILE
Kasiya concentrates have very low levels of sulphur. Sulphur can be difficult to remove in the purification processes required to produce anode materials. Other major impurities important for anode material purification processes are iron (Fe), silicon (Si) and aluminium (Al). The Kasiya material has exceptionally low levels of all of these impurities. Benchmarked against the Chinese Standard (China dominates the supply of graphite for battery anodes) this could potentially lead to significant commercial advantages during purification and Kasiya’s potential as a long term secure source of graphite ex-China.
