Name of the Project
Ancuabe graphite project.

Location
Cabo Delgado province, Mozambique.

Client
Triton Minerals.

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 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 from 900 000 t/y to 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 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.

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

Duration
Production is planned to start in the second half 2019, subject to financing and board approvals.

Latest Developments
Triton Minerals has signed a second binding offtake agreement for its Ancuabe project.

The agreement with China’s Qingdao Chengyang Graphite covers up to 16 000 t/y of graphite concentrate for at least five years, with a seller option for a further five years.

The minimum quantity under the offtake agreement is for 10 000 t/y across a range of graphite product specifications.

The selling price under the offtake agreement will be determined by the prevailing market prices in China.

The project is expected to produce its first graphite in the second half of 2019.
