Name of the Project
Ancuabe graphite project.

Location
Cabo Delgado province, Mozambique.

Project Owner/s
Triton Minerals. Shandong Tianye Mining (STM) has a 19.4% shareholding in Triton.

Project Description
Ancuabe has a maiden Joint Ore Reserves Committee-compliant ore reserve of 24.9-million tonnes at 6.2% total graphitic carbon based on the T12 and T16 mineral deposits.

A definitive feasibility study (DFS) on the deposits has confirmed the high quality, long life and high margin of the graphite project.

The DFS is based on the production of about 60 000 t/y of graphite concentrate over 27 years. The mine plan is based on the ore reserve, and less than 5% of the production is sourced from inferred mineral resources, which is mined to access the ore reserve.

It is planned that conventional drill-and-blast, load-and-haul, openpit mining will be used to extract the mineralised material. Run-of-mine (RoM) feed will be defined by grade-control procedures in the pit, and delivered by truck to the RoM pad located centrally between the T12 and T16 deposits. Waste will need to be classified according to its acid-forming potential and be dumped in managed waste dumps adjacent to the openpits. It is planned that mining will be carried out by an experienced earthmoving contractor.

Ancuabe’s process plant will have a throughput of between 900 000 t/y and 1.1-million tonnes a year to produce an estimated 60 000 t/y graphite concentrate. The proposed process plant facilities include:
• an RoM pad;
• a tertiary crushing circuit;
• a rod mill feed bin and grinding circuit;
• rougher flotation;
• three stages of attritioning and five stages of cleaner flotation;
• concentrate filtration;
• concentrate drying, classification and bagging of three products,
• tailings thickening and storage; and
• reagents.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The project has an unleveraged pretax net present value, at a 10% discount rate, of $298-million and an internal rate of return of 36.8%, with a near-term payback of 3.8 years.

Capital Expenditure
Preproduction capital costs are estimated at $99.4-million, including contingency.

Planned Start /End Date
Production is planned to start in the second half of 2019, subject to financing and board approvals. First production is expected in late 2020.

Latest Developments
Triton Minerals has launched a strategic review of its Ancuabe graphite project, to bring the project into production in the short term, at a small scale and on a commercially viable basis.

The strategic review will focus on the potential for scaling up the operations considered in the initial DFS, targeting production on a smaller scale, with a commercial pilot plant (CPP).

The CPP can be brought into production in the near term, producing commercially viable quantities of concentrate, which will prove the viability of the product and the large-scale project, at about 60 000 t/y, in the longer term.

In addition to providing validation of the process for potential funding partners, product from the CPP will enable Triton to generate further interest from potential offtake partners. The company told shareholders in September that it had made considerable progress with additional potential offtake partners to establish an offtake position covered by a number of buyers across a number of industries and geographical locations.
