Armadale Capital Plc (‘Armadale’ or ‘the Company’)
DFS update increases Mahenge NPV to $430 million
Armadale Capital plc (LON: ACP), the AIM quoted investment group focused on natural resource projects in Africa, is pleased to provide results for the updated Definitive Feasibility Study for its Mahenge Liandu graphite project (‘Mahenge’ or ‘the Project’) in south-east Tanzania, completed by experienced graphite specialists BatteryLimits.
The update, which is based upon a revised Mine Schedule using a higher-grade cut off of 9% Total Graphitic Carbon (‘TGC’), a higher strip ratio of 1.95:1, and a rescheduled Stage 2 expansion, results in the production profile increasing average annual output from 80ktpa to 109ktpa of concentrate over life of mine, which is a significant 30% increase on the recently completed Definitive Feasibility Study (‘DFS’).
Highlights
The delivery of the updated DFS delivery confirms the enormous commercial potential of Mahenge and will support ongoing discussions for binding offtake agreements, debt package finance for construction and project level development funding. Following these substantially improved economics to an already attractive Feasibility Study, a number of initiatives are currently advancing with respect to project financing and the Company hopes to be in a position to update the market shortly with respect to one or more of these workstreams.
Armadale Chairman, Nick Johansen, commented:
“The updated DFS demonstrates the exceptional potential of the Mahenge Liandu Graphite Project. The use of a higher-grade cut off and mining of a higher-grade material at an increased pace leaves significant scope for the Project to produce higher volumes of graphite over the 15 year mine life at a higher EBITDA margin, and as reflected in the significantly improved NPV figures greatly enhances its already attractive economics.
“The Mahenge project has a long mine life, low cost of production and has now been significantly de-risked at a time of rapidly increasing demand for large-flake graphite. As such it represents an attractive opportunity for investors who wish to gain exposure at a crucial inflection point in its development. The updated DFS reconfirms the enormous commercial potential of the Mahenge graphite project and lends strong support to our ongoing discussions for binding offtake agreements, debt package finance for construction and project level development funding – all workstreams which are in flight and advancing well and which we hope to provide further updates upon in the near future. In addition, important work continues with progressing workstreams in relation to Detailed Design Engineering, and the finalisation of the Company’s application for a full Mining Licence (and thus furthering major permitting milestones).
“Armadale has continued to deliver a number of key value accretive milestones in recent months and we look forward to maintaining this momentum in the near term in order to continue to build value for shareholders.”
Project update summary

Key financial metrics
The recently completed DFS confirmed Mahenge as a long-life low-cost graphite project with a US$358m NPV and IRR of 91% based on a two-stage expansion strategy.
The updated mining schedule and revision of the schedule stage 2 expansion from year 5 to year 4 has resulted in a 20% increase in project NPV to US$430m. The IRR remains at 91% with a modest less than 3% increase in capital to US$39.7m.
Further, the average LOM product sales price of $1,112/t reflects a more conservative product pricing assumption adopted for the update.

The DFS updated financial metrics show a significant improvement in the already compelling economics of the Mahenge project. The sensitivity analysis furthers shows robustness of the Project, where a 30% reduce in product pricing still results a US$192m NPV and IRR of 49%.
The DFS shows that Armadale can be a significant low-cost supplier to the graphite industry with the potential to generate pre-tax cashflows of US$985m over an initial 15 year mine-life and scope for further improvement as this utilises just 25% of the current resource, which remains open in multiple directions.
Projected timeline to first production is expected to be approximately 10-12 months from the start of construction and the capital cost estimate for Stage 1 is US$39.7m, which includes a contingency of U$S4.1m or 15% of total direct capital cost, with a 1.6 year payback for Stage 1 (after tax) based on an average sales price of US$1,112/t. Stage 2 expansion is expected to be funded from cashflow.
