About Critical Elements Lithium Corporation

Critical Elements Lithium Corporation aspires to be come a large, responsible supplier of lithium to th e

flourishing electric vehicle and energy storage system industries. To this end, Critical Elements Lithium is

advancing the wholly owned, high purity Rose lithium project in Quebec. Rose is our first lithium project to

be advanced within a highly prospective land portfo lio of over 700 square kilometers. In 2017, the

Company completed a robust feasibility study on Ros e Phase 1 for the production of high quality

spodumene concentrate. The internal rate of return for the Project is estimated at 34.9% after tax, wi th a

net present value estimated at C$726 million at an 8% discount rate. Capital and operating cost

parameters were confirmed in 2019 by Primero Group in the context of a Guaranteed Maximum Price

under an Early Contractor Involvement agreement, as a prelude to an Engineering, Procurement and

Construction process. Detailed engineering for Phas e I is expected to conclude this year as we also

deliver technical studies for Phase II, the convers ion of spodumene concentrate to high quality lithiu m

hydroxide. In our view, Quebec is strategically wel l-positioned for US and EU markets and boasts

exceptional infrastructure including a low-cost, lo w-carbon power grid featuring 93% hydroelectricity. We

have a strong, formalized relationship with the Cree Nation.
