OR FOR DISSEMINATION IN THE UNITED STATES

Critical Elements and Primero Announce a

Guaranteed Maximum Price for Engineering, Procurement and

Construction of the Rose Phase I Spodumene Project

October 23, 2019 – Montréal, Québec – Critical Elements Lithium Corporation (the

“Corporation” or “Critical Elements ”) (TSX-V: CRE) (US OTCQX: CRECF) (FSE: F12) is

pleased to announce Primero Group (“ Primero ”) has successfully completed the first phase of its

Early Contractor Involvement (“ ECI”) agreement with the Corporation, and that Primero has

provided a Guaranteed Maximum Price (“ GMP ”) for the engineering, procurement and construction

(“ EPC ”) of the Rose Lithium-Tantalum project (“ Rose ” or the “ Project ”) on a lump sum turnkey

basis that is in line with the Project’s feasibility study published November 29, 2017.

Critical Elements and Primero are in discussions to commence the second phase of the ECI

agreement (ECI Phase II – Front End Engineering Des ign) which will include initial detailed

engineering as well as determining fixed prices based on the GMP for Primero to perform all of the

work involved in completing the EPC lump sum turnke y proposal. Primero is also offering the

Corporation its EPC services as a fully integrated package if the final lump sum is within the GMP,

and if technical and commercial parameters are met during the second phase.

A summary of the ECI approach is included below:

 ECI Phase I – Guaranteed Maximum Price (completed) :

o Review and assimilate all of the existing design a nd data

o Stress test and optimize the design through review s, specific value engineering

and trade-off studies

o Reconfirm quantities and pricing

o Initiate selected engineering deliverables to achi eve nominally 25% engineering

definition

o Formulate a GMP for the process plant and associat ed process supporting

infrastructure

o Submit a proposal and schedule to progress to the next phase

 ECI Phase II – Front End Engineering Design (“ FEED ”):

o Progress and finalize a selected set of engineerin g deliverables to achieve

nominally 40% engineering definition

o Advance long lead and critical equipment packages to “Ready for Award” status

o Complete the contracting strategy and partnership for construction

o Optimize and reduce contingency applied to the GMP in order to formulate a

Lump Sum (the “ LS ”) cost estimate for the EPC of the process plant and

associated process infrastructure

o Submit a complete and firm proposal with schedule to Critical Elements for the

EPC-LS contract (the Corporation expects the lump sum cost estimated to be in

line with the feasibility study (Rose Lithium-Tantalum project feasibility study,

WSP, November 29, 2017))

o Execution of the EPC-LS

 Operation and maintenance support throughout scope of services

“Primero is thrilled to have worked alongside the C ritical Elements team. The GMP conclusion

underscores the skills and talent the Americas team in Montréal has in cold weather and hard rock

lithium projects, coupled with the in-house expertise in Perth, giving us another great rollout. Rose

is the latest addition to Primero’s Québec lithium portfolio. We couldn’t be more pleased” , stated

Jacques Parent, General Manager of Primero Group Americas.

Jean-Sébastien Lavallée, Chairman & Chief Executive Officer of Critical Elements stated, “ We are

very pleased with Primero’s work and the team. We said it before and continue to believe they are

the industry-leader in engineering and construction of spodumene plants.”

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

and a Qualified Person under NI 43-101, has reviewed and approved the technical content of this

release.

About Critical Elements Lithium Corporation

The Corporation recently released a financial analy sis for Critical Elements’ wholly-owned Rose

Lithium Tantalum project (Rose Lithium-Tantalum pro ject feasibility study, WSP, November 29,

2017), which is based on price forecasts of US $750/tonne for chemical-grade lithium concentrate

(5% Li2O), US $1,500/tonne for technical-grade lithium concentrate (6% Li2O) and US $130/kg for

Ta2O5 in tantalite concentrate, and an exchange rate of US $0.75/CA $. The internal rate of return

(“IRR”) for the Rose Lithium-Tantalum project is estimated at 34.9% after tax, and net present value

(“NPV”) is estimated at CA $726 million at an 8% di scount rate. The estimated payback period is

2.8 years. The pre-tax IRR for the Rose Lithium-Tan talum Project is estimated at 48.2% and the

pre-tax NPV at CA $1,257 million at an 8% discount rate (see press release dated September 6,

2017). The financial analysis is based on the Indic ated mineral resource. An Indicated mineral

resource is that part of a mineral resource for which quantity, grade or quality, densities, shape and

physical characteristics can be estimated with a le vel of confidence sufficient to allow the

appropriate application of technical and economic p arameters, to support mine planning and

evaluation of the economic viability of the deposit . The life-of-mine (LOM) plan provides for the

extraction of 26.8 million tonnes of ore, 182.4 mil lion tonnes of waste, and 11.0 million tonnes of

overburden for a total of 220.2 million tonnes of material. The average stripping ratio is 7.2 tonnes

per tonne of ore. The nominal production rate is es timated at 4,600 tonnes per day, with 350

operating days per year. The open pit mining schedule allows for a 17-year mine life. The mine will

produce a total of 26.8 million tonnes of ore grading an average of 0.85% Li2O and 133 ppm Ta2O5,

including dilution. The mill will process 1.61 mill ion tonnes of ore per year to produce an annual

average of 236,532 tonnes of technical and chemical grade spodumene concentrate and 429

tonnes of tantalite concentrate.
