ENQUIRIES

The Pre-Feasibility Study (PFS) confirmed Kasiya as a potential major critical minerals project with an extremely low CO₂-footprint delivering substantial volumes of natural rutile and graphite to global markets while generating significant economic returns.  

At the completion of the PFS, the Company commenced an optimisation study phase prior to advancing to the Definitive Feasibility Study (DFS). During the quarter, significant field activities and test work commenced.

The optimisation phase will be conducted in collaboration with the Company’s strategic partner, Rio Tinto, following their investment into the Company in July 2023.

Effective from 20 October 2023, the Company appointed Mr Frank Eagar as Managing Director and Chief Executive Officer (CEO). Dr Julian Stephens, transitioned to a Non-Executive Director of Sovereign, remaining as a consultant assisting and supporting the incoming technical and management team.

Mr Eagar has over 20 years’ experience in the financing, permitting, development and operation of mining projects with a strong focus in southern Africa.

Mr Eagar is a Chartered Accountant who has gained extensive corporate, commercial and technical experience in the mining sector throughout his career. Mr Eagar has previously held a number of senior executive positions in the resources sector, more recently with African mining focused private equity firm AMED Funds, which included acting as Chief Financial Officer (CFO) for AMED’s controlled company, Central Copper Resources PLC (Central Copper).

Prior to Central Copper, Mr Eagar was the CEO (and prior to that the CFO) of Baobab Steel Limited (Baobab) another AMED controlled company, where he managed the completion of a DFS and a joint venture with the World Bank’s IFC to procure strategic investors and raise project finance for Baobab’s US$1 Billion, fully permitted, integrated 500ktpa Steel and Vanadium Project in Mozambique.

Mr Eagar joined Sovereign in December 2022 as General Manager in Malawi, where he has already expanded the team with a focus on Malawian nationals, developed strong relationships with Government and developed a clear understanding of the Kasiya Project and its development landscape.

Sovereign has also made several key technical appointments as the Company transitions into project optimisation and development of the Kasiya Project and is poised to become a significant supplier of natural rutile and graphite. These key appointments bring a strong track record of successful large-scale project development and operations management, as well as extensive experience in southern Africa.

These management changes come at an important time for the Company as it transitions from the PFS into the next study phases including optimisation, community and stakeholder engagements and project permitting.

During the quarter, Sovereign completed the extraction of a 60 tonne bulk sample of ore from Kasiya to produce an initial 600kg of natural flake graphite. This sampling program is part of the Company’s graphite qualification, product development and downstream battery anode test work phase. A major component to graphite sales agreements is customer qualification with graphite produced from this program to be shared with prospective end-users in addition to being used for upscaled downstream test work.

The mechanised drill program used a bespoke 300mm diameter spiral auger to extract the material from across Kasiya’s planned future pits with sampling to a maximum 20m depth.

The bulk sample is undergoing pre-processing at the Company’s laboratory in Lilongwe, Malawi. The sample is being processed utilising the newly installed Kwatani 30-inch single and double-deck vibrating separators for sizing and de-sliming (Figure 3). The sand fraction is then processed over the new Holman Wilfley 2000 wet shaking table to produce a graphite pre-concentrate and a separate heavy mineral concentrate (HMC) containing the rutile (Figure 4). The graphite pre-concentrate is expected to grade 4-5% C^t.

Final processing will then be completed at international commercial laboratories. The graphite pre-concentrate will undergo traditional flotation and polishing processes to target >96% C^t product suitable as a lithium-ion battery anode feedstock.

Downstream Test work

The initial ~600kg of flake graphite product produced will be used for downstream test-work and product qualification targeting the battery anode sector. Previously reported initial characterisation test work on Kasiya’s graphite has indicated excellent suitability for use in lithium-ion batteries with very high purity and very high crystallinity being the key features (refer to ASX Announcement dated 8 June 2023).

Downstream test-work and qualification on the flake graphite product will involve the following stages to be completed at recognised international battery sector laboratories;

–    Purification to >99.95% Ct

–    Micronisation

–    Spheronisation

–    Carbon coating

–    Anode production

–    Electrochemical characterisation

Raw flake graphite products plus final CSPG (coated spheronised graphite product) will be provided to potential offtakers for assessment and pre-qualification. Through Sovereign’s long-term experience in graphite, the Company has built a strong understanding of the graphite market and developed well-established relationships with offtakers and customers.

Industry Developments

The upscaled graphite program comes as China implements curbs on exports of natural graphite under “national security” concerns. Effective 1 December 2023, China requires export permits for some graphite products including natural graphite and natural graphite products critical to EV production. China is the world’s top graphite producer and exporter and also refines more than 90% of the world’s graphite into the material that is used in virtually all EV battery anodes.

China’s commerce ministry said the move on graphite was “conducive to ensuring the security and stability of the global supply chain and industrial chain, and conducive to better safeguarding national security and interests”.

Since the restrictions, total exports of flake graphite dropped by 94% on a monthly basis in December, while exports of spherical graphite slumped by 92% (China customs data). Exports to major destinations also slowed notably in December. Flake graphite volumes to Japan fell from 6,138 tonnes in November to zero in December, while exports to the United States fell from 511 tonnes in November to zero in December (Fastmarkets). It was reported by Japan News, that, Japan, which depends on China for 90% of its graphite imports, likely needs to urgently diversify its procurement sources.

Kasiya is one of the world’s largest natural flake graphite deposits and has the potential to become a key source of long term strategic supply to the US, UK, EU, Japan and South Korea.

Subsequent to the quarter, Sovereign appointed SocialEssence (Pty) Ltd (SocialEssence), an Africa-based specialist social performance consultancy, who will assist in the continued development of the Company’s stakeholder relations, social performance objectives and its Community and Social Responsibility (CSR) framework. 

Sovereign has engaged SocialEssence to design and execute social performance activities during the DFS phase. Founder, Mr Garth Lappeman, has over 16 years of on the ground social performance planning and implementation experience in accordance with IFC Performance Standards and World Bank Environmental, Health and Safety Guidelines. SocialEssence has been active in a number of countries working on projects in Angola, Botswana, Democratic Republic of Congo, Kenya, Kyrgyzstan, Liberia, Malawi, Mozambique, Namibia, Panama, Uganda, Sierra Leone, South Africa, Northern Sudan, Tanzania, Uzbekistan, and Zambia.

Most notably, in Zambia, SocialEssence’s Director was involved from early exploration through to steady state production of First Quantum Minerals Ltd’s (First Quantum Minerals) Trident operations, which includes the Sentinel Copper Mine which is of similar scale to Sovereign’s Kasiya project. Mr Lappeman was responsible for implementing and managing social and community initiatives for First Quantum Minerals as it established its large-scale commercial operations

SocialEssence will:

·      prepare Kasiya’s Social Impact Assessment and Management Plan for the DFS and permitting;

·      design, implement and manage social performance activities including stakeholder engagement, development of key relationships;

·      prove the feasibility of critical social performance measures (including early local content, and piloting of livelihood restoration programs, and piloting of rehabilitation activities to restore land for agricultural use); and

·      align with the Company’s ESG Framework.

Sovereign is currently conducting an optimisation study prior to advancing to the DFS. The Company aims to become the world’s largest, lowest cost and lowest-emissions producer of two critical minerals – titanium (rutile) and graphite. The Company plans to update the market on the progress of the following in coming months:

·     Further appointments to owner’s team to build on the Company’s execution capabilities;

·     Results of graphite product development, downstream and qualification test work;

·     Regional hand-auger drilling on mineralisation extensions;

·     Progress on the optimisation work streams alongside Rio Tinto via the project Technical Committee; and

·     Community and social engagements across Malawi and the Kasiya area.
