Outstanding detailed feasibility study results support Talga’s anode project

Posted By Graphene Council, Wednesday, August 5, 2020

Talga is pleased to advise the outcomes of feasibility work and studies completed on its Vittangi Anode Project (“Project”) in northern Sweden.

Talga is building an integrated graphite anode facility in Sweden running on 100% renewable electricity, to produce ultra-low emission coated anode for greener lithium-ion (“Li-ion”) batteries. Production of the Company’s flagship fully coated anode product, Talnode®-C, will be based initially on the unique flake graphite of its Nunasvaara South deposit near Vittangi.

Project development has  been  marked  by  operational  impacts  during  the  COVID-19  pandemic. In consideration of these impacts, the development of the Project will now be combined into a single commercial stage, amalgamating the two stages previously outlined in the Project Pre-feasibility Study (“PFS”). The overall economic and financial parameters for the combined stages remain materially unchanged from the PFS.

Since the publication of the PFS in May 2019 Talga has undertaken further studies into the Talnode-C product, anode production, graphite processing and battery market as part of detailed feasibility work on the Project.

Completed feasibility work on the start-up phase (Stage 1) of the Project show highly positive outcomes which will be refined further in the upcoming commercial Detailed Feasibility Study (“DFS”). Improvements in Project performance identified in the latest feasibility work include:

• Project development to proceed directly to commercial phase with Project commissioning in 2022 and commercial production in 2023, subject to commercial DFS planned for Q1 2021
• Yield of Talnode-C (from graphite concentrate) increased to 99%, up from 88% in PFS
• Total recovery of Talnode-C (from graphite ore) increased to 90%, up from 80% in PFS
• Energy savings of 30% in graphite concentrate production
• Successful piloting of proprietary sustainable purification process producing battery-grade graphite concentrate without use of industry standard hydrofluoric acid (“HF”)
• Ability to produce Talphene graphene products for battery and polymer composite applications from anode refinery stream
• Positive feedback on Talnode-C from major battery manufacturers including high capacity and fast- charge performance during qualification tests
• Refinement of Talnode-C coating treatment based on input from automotive OEM customers
• Pre-production scale Talnode-C pilot plant to satisfy larger automotive OEM qualification process
• Further cost optimisations and growth opportunities identified including resource expansion and underground mining options

The fast track pathway simplifies Project development and enables the Company to progress directly to commercial anode production of 19,000 tonnes per annum (“tpa”) with commencement of construction in 2022 and production in 2023, as outlined in the  PFS.  Talga’s potential Project partners and customers have indicated that they support this plan.

Commenting on the feasibility study results, Talga Managing Director Mark Thompson said: “I credit our staff members and technical partners for their work in realising these significant improvements which span every area of our anode project development. In spite of COVID-19 disruptions our commercial development remains firmly on track thanks to the ingenuity of the Talga team. The great results of the recent feasibility work shows significant benefits to be gained in the short and long term and support the simplified amalgamated development plan.

With increasing demand for Li-ion battery anode sourced from secure and clean supply chains Talga is attracting attention as a potential major anode producer outside China. The range of parties we are engaged with, from product sales to project development partnerships, are truly world-class and well-suited to our project execution strategy. We look forward to sharing more results of these partnerships over the coming months.”
