Triton Minerals Ltd.'s definitive feasibility study for its Ancuabe project in Mozambique estimated a pretax net present value, discounted at 10%, of US$298 million, a 36.8% internal rate of return and a 3.8-year payback period.
The company also estimated a maiden ore reserve of 24.9 million tonnes at 6.2% total graphitic carbon for 1.5 million tonnes of contained graphite.
The definitive feasibility study was based on annual production of about 60,000 tonnes per annum of graphite concentrate over the evaluation period of 27 years, according to the Dec. 15 release.
At a graphite concentrate basket price of US$1,435 per tonne, EBITDA for the project was estimated at US$1.18 billion.
The preproduction cost, including contingency, is estimated at about US$99.4 million, and operating costs, excluding royalties, are expected to be US$634 per tonne of graphite concentrate.
Triton will now focus on finalizing off-take agreements, financing arrangements, local approvals and early works engineering and procurement to enable a final investment decision in the first half of 2018.
A recent updated resource estimate for Ancuabe totaled indicated and inferred resources of 46.1 million tonnes at 6.6% TGC for 3.0 million tonnes of contained graphite.
Under the definitive feasibility study, less than 5% of the production will be sourced from inferred mineral resources, which will be mined to access the ore reserve.
