Name of the Project
Mahenge Liandu graphite project.

Location
Tanzania.

Client
Armadale Capital.

Project Description
The Mahenge Liandu deposit is one of the highest-grade, large-flake deposits globally after the recent upgrade to 51.1-million tonnes at 9.3% total graphitic carbon (TGC), including 38.7-million tonnes in the indicated category at 9.3% TGC and 12.4-million tonnes in the inferred category at 9.1% TGC.

The scoping study completed on the project is based on a throughput of 400 000 t/y, producing an average of 49 000 t/y of high-quality graphite products during a 32-year life-of-mine.

The deposit has a low average strip ratio of 1:1 for the life of the mine and a very low operating cost of $408/t. There remains significant scope to further improve returns using staged expansions, as the current mine plan is based on about 25% of the total resource.

Latest Developments
Armadale Capital has signed a memorandum of understanding (MoU) for a proposed offtake agreement with Chinese graphite mining and processing company Matrass Group, for graphite products produced at the Mahenge Liandu project.

The MoU pertains to the proposed offtake of 30 000 t/y of graphite concentrate for an initial five-year term at a price to be agreed based on the Chinese benchmark for the quality of the graphite produced, and representing more than 60% of Mahenge Liandu’s average targeted yearly production.

A testwork programme, aimed at progressing the MoU to a binding agreement, is planned to start before the end of March. 

Armadale has entered into discussions with several potential customers regarding the remaining 19 000 t/y of production. These discussions are ongoing.

Meanwhile, the feasibility study drilling on the project has been completed with further site activities expected to restart in the coming weeks once the Tanzanian wet season has ended.

Moreover, the environmental- and social-impact assessment has been completed, with the valuation study returning lower-than-planned relocation costs, which further enhanced the economics of the project.
