“Completion of the feasibility study is a significant milestone along the development path of our Molo graphite project,” stated Richard Schler, Chief Executive Officer of Energizer. “We have now confirmed that our project is economically viable with a planned mine design that we believe is both conservative and realistic. It indicates the project has attractive economics and that we have one of the lowest operating costs in the industry. Our graphite deposit is large enough to realize a very long mine life and the plant is scalable so we can quickly ramp up production if so required. The plant will be able to produce a high quality graphite concentrate, which can supply the entire spectrum of end uses for natural graphite including the foil and Electric Vehicle battery markets.
I would like to take this opportunity to thank everyone who has contributed to reaching this milestone including our shareholders who have waited patiently for the delivery of the study. The culmination of hard work and dedication over the past 4 years in some very difficult resource market conditions has enabled Energizer to validate an exceptional project that is positioned to serve an industry, which is expected to have significant demand growth over the next decade.
We believe this will be the stepping stone to help secure both off-take and project financing in the near future. We will now turn our entire focus towards delivering on these objectives over the coming months with a goal to be in production by 2017.”
The FS considers a mine that will produce an average of 856,701 tonnes per annum of ore, which is processed to produce an average of approximately 53,017 tonnes of graphite concentrate per annum (production commencing in 2017) over the 26 year life of mine (“LOM”). The FS assumes that the mine is funded on a 50% debt and 50% equity basis. ‘Steady State’ (or “Run Rate”) costs are achieved in the third operational year onwards; the difference lies in additional expatriates on site in the first two years.

All capital and operating costs expressed above are considered to be accurate to +/- 10%, and assume a varying inflation rate of 1.6% in 2015 and escalating to 2.0% from 2017 onward. Currency inflation rates were also considered in the financial model.
Transport (Molo Site to European customer)
Average transport cost: US$337 per tonne of concentrate (from Mine site to Europe via Fort Dauphin, Madagascar, in December 2014 terms)
DRA has not included any financial or operational calculations and/or scenarios in the FS financial model with regards to downstream value-added processing of the graphite concentrate. This includes purification, spherodization coating for battery-grade graphite and thermal expansion for specialty graphite applications, such as foils.
The exchange rates used in the financial model are as follows:
- 11.31 South African Rand (ZAR) to US$1,moving in line with purchasing power parity
- 0.833 Euro to US$1, fixed for the modelled period
- 2,746 Malagasy Ariary (MGA) to US$1, moving in line with purchasing power parity
The graphite prices are based on current quotes and projected estimates provided by UK-based Roskill Consulting Group Ltd (“Roskill”), who are recognized as a leader in providing independent and unbiased market research, pricing trends and demand and supply analysis for the natural flake graphite market.
The FS “2017 Start-Up” price for a tonne of Molo graphite concentrate was calculated from the weighted average price per tonne of US$1,375 (in December 2014 terms, considered by Roskill to be the bottom of the market), which is a continuation of trends from 2005 (excluding the 2010 to 2013 unusually high graphite concentrate prices). The price shown is the weighted average price for the various flake sizes and grades of flake graphite that are expected to be produced from the Molo deposit.
A summary of certain significant differences between the FS and the Company’s Molo Preliminary Economic Assessment Study (“PEA”) are as follows:
- The PEA assumed 1.16 million tons (“MT”) per annum of ore, resulting in 84,000 tpa of graphite concentrate.
- The PEA CapEx estimate accuracy was +/- 25%, based on order of magnitude estimates.
- There has been a reduction in head grade to the plant from 8.5% C to 7.04% C.
- The FS includes delivery costs to Europe.
- The FS has assumed 50% debt funding on an eight operational year basis, whereas the PEA assumed 57% debt on 10 years.
- The FS has a more well defined flow sheet.
The proposed development of the Molo graphite project includes the construction of an open pit mine, a processing plant with a capacity of 862,000 tonnes of ore per annum and all supporting infrastructure including water, fuel, power, tailings, buildings and permanent accommodation.
The mine will utilize four 2 megawatt diesel generators, with three running and one standby by and water is supplied from a well field which has been defined by drilling and geo-hydrological modelling. The processing plant will consist of conventional crushing, milling and flotation circuits followed by concentrate filtering, drying and screening. The waste heat generated by the power station will be utilized for the drying of the concentrate.
The tailings storage facility, in the form of a valley dam layout, is located approximately 1.5 kilometres to the west of the process plant and is designed to accommodate the run-of-mine tonnage for the 26 year life of mine.
The Molo project hosts the following resources:
- Measured mineral resource of 23.62 MT grading 6.32% carbon (“C”).
- Indicated mineral resource of 76.75 MT grading 6.25% C.
- Inferred mineral resource of 40.91 MT at 5.78% C.
Effective date of the Mineral Resource tabulation is August 14, 2014. The Mineral Resources are classified according to the Canadian Institute of Mining definitions. A cut-off grade of 4% C was used for the “higher grade” zones and 2% C for the “lower grade” zones. Please note that while the ‘high’ grade resource occurs within the ‘low’ grade resource, each was estimated and reported separately. A relative density of 2.36 tonnes per cubic metre was assigned to the mineralized zones for the resource estimation. The resource remains open along strike and to depth. The Mineral Resources above are inclusive of the Mineral Reserves below.
PROVEN AND PROBABLE MINERAL RESERVES
As a result of the FS, the following maiden proven and probable mineral reserves are declared.
|Category||Tonnage||C Grade (%)|
|Proven and Probable||22,437,000||7.02|
Proven reserves are reported as the Measured Resources inside the designed open pit and above the grade cut off of 4.5% C. Similarly, the Probable Reserves are reported as the Indicated Resources inside the designed open pit and above the grade cut-off of 4.5% C.
The FS is based on a full suite of metallurgical test work performed by SGS Canada Metallurgical Services Inc. in Lakefield, Ontario, Canada. These tests included lab and bench scale process development work, a bulk sample/pilot plant program, and metallurgical variability testing. The tests indicated that variability exists across the deposit but this has been mitigated by the design of the flow sheet. The overall graphitic carbon recovery into the final concentrate is 87.8% using samples from all drill holes within the five year pit design. The average composition of the combined concentrate grade is presented in the table below.
The area composites were generated by splitting the area within the five-year mine plan into five zones. All drill holes within one specific zone were then combined to form an area composite. A total of fifteen area composites were generated for metallurgical evaluation (five zones with three depth intervals per zone). All assays were completed using control quality analysis and cross checks were completed during the mass balancing process to verify that the results were within the relative error of the analytical method.

ENVIRONMENTAL & PERMITTING
A comprehensive Environmental and Social Impact Assessment (“ESIA”) was completed to local Malagasy, Equator Principles, Word Bank and International Finance Corporation (IFC) standards. The process was preceded by an Environmental Legal Review and an Environmental and Social Screening Assessment; both providing crucial information to align the project development and design with international best practice on sustainable project development.
The ESIA submission is subject to approval of the investment amount by Madagascar’s Ministry of Mines, which is anticipated in February 2015. The application was submitted on January 30, 2015. Energizer will receive a Global Environmental Permit upon approval of the ESIA, a process which is expected to take six months from date of submission.
A comprehensive permitting register is in place and additional sectorial permit applications will form part of the early execution phase. Approval of the sectorial applications is expected within the same six month period as the ESIA review.
No material issues were identified in relation to Environmental, Social and Permitting processes and through the stakeholder engagement process the local and regional community has expressed a desire for the project to move forward.
