- Mine planning process updated to reflect results of completed drilling programme
- Product quality wide diameter drilling completed to create representative concentrates and test work to optimise process flow sheet by determining recovery rates, flake size distribution and final product purity
- 1.6 tonnes of diamond core sent to Perth, Australia where it will undergo metallurgical testing that will enable completion of the final plant design
- Environmental Social Impact Assessment (“ESIA”) and Relocation Action Plan (“RAP”) finalised and expected to be submitted to the National Environment Management Council (“NEMC”) this month
- Test work programme aimed to progress the MOU for offtake of 30,000tpa of graphite concentrate to a binding agreement underway
- Discussions progressing with further offtake partners for remaining 19,000tpa of graphite concentrate
- Application for a mining lease expected to be submitted in August 2019
- Graphite market continues to strengthen with a number of Tanzanian based graphite projects securing binding offtakes over recent months
Nick Johansen, Director of Armadale said: “The Mahenge Liandu Graphite deposit is one of the highest-grade large flake deposits globally with a current JORC Resource of 51.1Mt at 9.3% TGC. With work now underway to upgrade this Resource to declare a Maiden Reserve, the potential of the Project is set to increase. We are now working on securing the mining permit and completing the Definitive Feasibility Study which will allow us to make the decision to mine and ultimately advance Mahenge Liandu into production.
“The Scoping Study released in March 2018 demonstrated an NPV of US$349m and IRR of 122%. Project capex drawdown was US$35m demonstrating the potential for an extremely low project development cost, with a payback estimated of 1.2 years and a 32-year life of mine. We expect the DFS to confirm our confidence in the extremely compelling economics of the Project.
“We are encouraged by the strengthening graphite market which has been reflected across a number of comparable graphite-projects that are securing project finance and advancing to mine construction. The Tanzanian government is now actively recognising the requirement for foreign investment in the mining sector and we are pleased to note the accommodating investment conditions.
“I look forward to reporting further as our DFS and partner discussions continue. The Company will release regular updates as material developments occur, including those areas covered in the ongoing work streams outlined below.”
Mahenge Liandu Background
The Company published a Scoping Study in March 2018 which demonstrated the following economics:
- Net Present Value (“NPV”) of US349million;
- Development CAPEX of US$35million;
- Pre-tax Internal Rate of Return (“IRR”) of 122%;
- 32-year life of mine with an after-tax payback period of 1.2 years.
This Scoping Study was based on an upgraded Total Graphitic Carbon (“TGC”) JORC compliant Resource published by the Company in February 2018, which demonstrated that the deposit is one of the highest grade large flake deposits globally with 51.1Mt at 9.3% TGC including 38.7Mt Indicated at 9.3% and 12.4Mt Inferred at 9.1% TGC.
The Scoping Study that was published in 2018, only reflects 25% of the Mahenge Liandu’s JORC Compliant Resource, and generates a 32-year life of mine. The deposit is accessible with cost-effective open pit mining methods. As part of the DFS an infill drilling programme targeting near surface high-grade mineralisation, was successfully completed confirming the Company’s confidence in the Resource.
The Project economics at scoping level indicated considerable upside against CAPEX requirements. Based on the assumed financial model, the substantial free-cash flow generated in the event of a mining operation would provide the Company with significant working capital to conduct exploration programmes with a view to increasing throughput by staged expansions.
Based on the Scoping Study findings the Company announced the commencement of a DFS in May 2018 which is based on a throughput of 400,000tpa over a 32-year mine life and involves a range of activities which are progressively being completed, these include:
- A diamond drilling programme to obtain samples for metallurgical test work and marketing;
- An infill RC drilling programme over the initial planned mining area;
- An airborne topographic survey over the area of the proposed mining licence;
- Product marketing towards the goal of achieving binding offtake agreements;
- Environmental and social studies covering the Project area and completion of a Relocation Action plan (“RAP”) for the people who may be impacted through the development of the Project;
- Progressing towards application of mining permits;
- A geotechnical drilling programme to define the final pit wall design;
- Calculation of Proved and Probable Reserves;
- The construction of water production bores to determine the flow rates and ground water conditions in the Project area;
- Finalisation of production flowsheets and final plant design parameters.
Progress to Date and Ongoing Work Streams
Resource and Reserve Definition
The Company announced completion of RC and diamond drilling programme in August 2018 with all holes intersecting wide intervals of high-grade mineralisation from surface with up to 67m thickness. Drilling focused on the proposed initial mining area and the results have been incorporated into the mine planning process.
The intention of the drilling programme was to have at least ten years of planned production in the Measured JORC compliant category. The Company has now undertaken sufficient drilling to achieve this and is finalising the Reserve calculations with mine engineering advisers. A Reserve update to market is expected to be released as part of and together with the completion of the DFS.
Product quality wide diameter drilling has also been completed to create representative concentrates and test work thereon will provide data on graphite recovery rates, flake size distribution and final product purity.
The Company sent a shipment of 1.6 tonnes of diamond core to Perth, Australia which will undergo metallurgical testing to produce a concentrate that will enable completion of the final plant design. The concentrate samples will be used to further assist commercial discussions and for downstream product test work.
The results of metallurgical test work for product quality are expected in June 2019. Downstream test work results confirming product quality are expected in July 2019.
Definitive Feasibility Study Completion
Multiple work streams are underway on various additional areas of the technical Feasibility Study which include:
- Product marketing roadshow to potential end users in June 2019;
- Development of the transport and logistics pathway – expected to be finalised in June 2019;
- Resource update targeting high grade near surface mineralisation – expected in June 2019;
- Metallurgical work results confirming product quality and downstream test-work confirming the potential uses of Mahenge Liandu Concentrates – expected July 2019;
- Updating and optimisation of the pit design expected to be finalised in September 2019,
- Construction of water bores and assessment of flow rates and ground water conditions is which is expected to be completed by November 2019 and;
- Overall completion of the full DFS is expected in November 2019.
Environmental and Social Studies
During August 2018 the Company also announced the completion of field work for Environmental and Social baseline surveys and the Company has finalised the Environmental Social Impact Assessment (“ESIA”) and Relocation Action Plan (“RAP”) with both documents expected to be submitted to the National Environment Management Council (“NEMC”) this month.
To help increase local engagement in the Project area, the Company has appointed a community liaison officer who will aid understanding of the impact and benefits of mining in the region. Further information in respect of this work of will be provided as progress is made.
Product Marketing and Offtake Partners
In February 2019 the Company announced a Memorandum of Understanding (“MOU”) with the Matrass Group, a China based graphite mining and processing company, for high quality graphite products produced at Mahenge Liandu. This includes a proposed offtake of 30,000tpa of graphite concentrate for an initial five-year term at a price to be agreed based on the Chinese benchmark for the quality of the graphite produced, representing over 60% of average target annual production.
The test work programme aimed to progress the MOU to a binding agreement is underway. Discussions with other potential offtake partners for the remaining 19,000tpa of graphite concentrate are also progressing positively.
The graphite market continues to strengthen with a number of Tanzanian based graphite projects securing binding offtakes over recent months. The rapid expansion of the electric vehicle market is expected to continue to drive this growth.
Project Level Financing
The Company is also engaged in discussions to secure a project level funding mandate. Further details in respect of this element will be provided as material developments occur.
Mining Lease Application
Reflecting the progress of work to date, the Company expects to submit its application for a mining lease in August 2019.
Front End Engineering Design
Following completion of the DFS the Company expects to commence the Front-End Engineering Design (“FEED”) work programme in December 2019. The FEED process is a detailed technical project planning phase undertaken prior to the commencement of construction and used as a basis to secure project construction bids.
Subject to successful and timely completion of the above preparatory work, suitable project level financing and the receipt of relevant regulatory permits and licences, the Company expects to commence the construction phase in Q2 2020.
Based on current estimates and assuming a construction phase of 10 months the first production would be achieved from the Mahenge Liandu project around Q1 2021.
