Nemaska Lithium Releases Updated NI 43-101 Technical Report

• Before-Tax Internal Rate of Return (IRR) at 30.3% and Net Present Value (NPV) @ 8% of CAD 3.1 B
• After-Tax IRR at 27.4% and NPV @ 8% of CAD 2.3 B
• CAPEX assessment for Whabouchi and Shawinigan confirms the Corporation’s February 2019 estimate

QUEBEC CITY, July 31, 2019 -- Nemaska ​​Lithium Inc. (“Nemaska Lithium” or the “Corporation”) (TSX: NMX) (OTCQX: NMKEF) (Frankfurt: N0T) releases the results of its updated National Instrument (NI) 43–101 Technical Report (the “Report”) on the Whabouchi mine (“Whabouchi”) and Shawinigan electrochemical plant (the “Plant”) (together, the “Project”). Nemaska Lithium’s management team retained the services of engineering firms to make this Report (as defined in NI 43–101), following the Corporation’s funding gap announcement of February 13, 2019.

“We are pleased to inform our shareholders that the Project’s economics remain very robust after a thorough review of the capital investment (‘CAPEX’) and overall operating costs (‘OPEX’) by the Qualified Persons (“QP”) working closely with our strengthened owner’s team, as reflected by the Report. It was produced using the most recent detailed engineering designs for both sites that provide significant insight into key operational estimates,” said Guy Bourassa, President and CEO of Nemaska Lithium. “Now that we have an updated timeline and budget, and that we have received and accepted a letter of intent from Pallinghurst for an equity investment of up to CAD 600 M, we are confident that we have in hand a solid plan for the future as well as a strong team in place to resume construction and successfully deliver the Project once the required financing is completed.”

Assuming a 100% Project equity financing, the Report shows a before-tax IRR % and NPV (@ 8% discount) of 30.3% and CAD 3.1 B, respectively and an after-tax IRR % and NPV (@ 8% discount) of 27.4% and CAD 2.3 B, respectively. These NPV and IRR calculations exclude sunk costs of ~CAD 340 M, as per NI 43–101 standards. It is assumed that the financing would be in place in order for construction to resume in November 2019, which would lead to a start of production in June 2020 for Whabouchi and in November 2021 for the Plant.

Updated Report at a Glance

Following an update of the geological model and detailed mine planning, the Report confirms a revised estimated annual production of approximately 205,000 tonnes of concentrate from Whabouchi and an annual production of approximately 37,000 tonnes of high-quality lithium hydroxide monohydrate at the Plant; assuming Nemaska Lithium will purchase lithium sulfate monohydrate (LSM) and/or concentrate when needed to achieve nameplate capacity.

The Corporation has made the decision to focus on lithium hydroxide production at its Plant; however, the Corporation will have the capacity in the future to add, as needed, the equipment required to also produce lithium carbonate should the market demand justify it.

The advancement of detailed engineering since June 2018 and the optimizations performed during the preparation of the Report have significantly de-risked the Project.

Including the costs related to the ramp-up and start-up of operations, the updated overall Project average OPEX are estimated to total CAD 5,223 (USD 4,018) per tonne of lithium hydroxide monohydrate (LiOH-H₂O) produced from the Whabouchi concentrate. The OPEX per tonne of concentrate (6.25% Li₂O) delivered at the Plant is estimated at CAD 452 (USD 347) on average during the life of mine (LOM). For the Plant, the overall estimated OPEX for the conversion of concentrate from the Whabouchi mine would be of CAD 2,513 (USD 1,933) per tonne of lithium hydroxide monohydrate (LiOH-H₂O) on average over the life of the Project.

“We are proud of the efforts our renewed owner’s team has put forward over the past few months to strengthen control over engineering and construction activities. With the precious support of the whole organization, we will always be looking for ways to continuously improve our cost structure once we reach production level, thus strengthening Nemaska Lithium’s competitive position as a preferred low-cost producer of high-quality battery grade lithium hydroxide monohydrate” added Robert Beaulieu, Vice President, Operations and Construction. “The completion of this update provides us with the highest possible degree of visibility on key operational imperatives for the completion of construction, commissioning and ramp-up of our Project.”

¹The total CAPEX includes amounts for corporate owners’ costs, which are ≈CAD 42 M for Whabouchi and ≈CAD 29 M for the Plant.

² The NPV and IRR exclude sunk costs of ~CAD 340 M from calculations. This is the NI 43–101 standard.
