C RITICAL E LEMENTS SUBMITS AN E NVIRONMENTAL IMPACT STUDY

FOR ITS R OSE L ITHIUM - T ANTALUM P ROJECT

A UGUST 2 ND , 2017 - M ONTREAL , Q UEBEC – Critical Elements Corporation (the “Corporation” or “Critical

Elements”) (TSX - V: CRE) (US OTCQX: CRECF) (FSE: F12) has announced that its environmental

impact study ( “ EI S ” ) for the Rose L ithium - T antal um P roject was officially submitted to the Environmental

and Social Impact Review Committee ( “Committee” or “COMEX” ) and the Canadian Environmental

Assessment A gency ( “ C EAA ” ).

S ubmission of the EIS, which was developed by WSP, is an important step in the process of obtaining

authorization for the project. The EIS was submitted to COMEX in accordance with Chapter II of the

Quebec Environment Quality Act and to t he CEAA in accordance with the Canadian Environmental

Assessment Act ( 2012).

The environmental impact study conducted as part of the potential startup of the Rose Project sets out

the environmental footprint of the project, the methods for identifying po tential social and territorial

impacts, and the various initiatives proposed .

“The EIS is a recognized tool for ensuring better integration of projects in the community and contributing

to sustainable development," said Jean - Sébastien Lavallée, Chairman a nd CEO of the Company .

“Submitting this study is very important to us and it represents a major step in the process to bring about

the Rose L ithium - T antalum P roject . We believe it’s critical to carefully analyze the impacts, both

environmental and social, and we will improve each and every aspect that we can. The study is now in

the hands of competent authorities and we are open to discussing findings and next steps with them.”

Jean - Sébastien Lavallée (OGQ # 773), geologist, shareholder, Chairman and CEO of the Corporation,

and “Qualified Person” under Regulation 43 - 101, revised and approved the technical content of this press

release .

A BOUT C RITICAL E LEMENTS C ORPORATION

A recent financial analysis (Technical Report and Preliminary Economic Assessment (PE A) on the Rose

lithium - tantalum Project, Genivar, December 2011) of the Rose project, 100% owned by Critical

Elements, based on price forecasts of US $260/kg ($118/lb) for Ta 2 O 5 contained in a tantalite concentrate

and US $6,000/t for lithium carbonate (Li 2 CO 3 ) showed an estimated after - tax Internal Rate of Return

(IRR) of 25% for the Rose project, with an estimated Net Present Value (NPV) of CA $279 million at an

8% discount rate. The payback period is estimated at 4.1 years. The pre - tax IRR is estimated a t 33% and

the NPV at CA $488 million at a discount rate of 8%. (Mineral resources are not mineral reserves and do

not have demonstrated economic viability). (The preliminary economic assessment is preliminary in

nature). (See press release dated November 21, 2011.) The PEA includes inferred mineral resources

that are considered too speculative geologically to have economic considerations applied to them that

would enable them to be categorized as mineral reserves and there is no certainty that the prelimin ary

economic assessment will be realized.

The conclusions of the PEA indicate that the operation would support a production rate of 26,606 tons of

high purity (99.9% battery grade) Li 2 CO 3 and 206,670 pounds of Ta 2 O 5 per year over a 17 - year mine life.

The project hosts a current Indicated resource of 26.5 million tonnes of 1.30% Li 2 O Eq. or 0.98% Li 2 O and

163 ppm Ta 2 O 5 and an Inferred resource of 10.7 million tonnes of 1.14% Li 2 O Eq. or 0.86% Li 2 O and 145

ppm Ta 2 O 5 .
