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 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 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.

Latest Developments
The Mozambique government has granted Triton Minerals a mining concession for its Ancuabe graphite project, paving the way for project development.

The granting of a mining concession is a critical element of the financing process, which is progressing well, Triton MD Peter Canterbury has said.

“Triton has now signed binding offtake agreements for approximately 53% of annual production from Ancuabe, has executed an engineering, procurement and construction contract with MCC International, has been granted its mining concession, which is the final approval required to commence production at Ancuabe, as well as having signed a project investment, finance and offtake memorandum of understanding (MoU) with Qingdao Jinhui Graphite and various other MoUs for offtake and graphite product marketing,” Canterbury notes.
