A BOUT C RITICAL E LEMENTS C ORPORATION

The Company recently released a fin ancial analysis for Critical Elements’ wholly - owned Rose Lithium -

Tantalum project (Rose Lithium - Tantalum project feasibility study, WSP, October 20, 2017), which is

based on price forecasts of US $750/tonne for chemical - grade lithium concentrate (5% Li 2 O), US

$1,500/tonne for technical - grade lithium concentrate (6% Li 2 O) and US $130/kg for Ta 2 O 5 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% aft er tax, and net present value (“NPV”) is

estimated at CA $726 million at an 8% discount rate. The estimated payback period is 2.8 years.

The pre - tax IRR for the Rose Lithium - Tantalum 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 Indicated 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 level of confidence sufficient to allow the appropriate application of technical and

economic parameters, to support mine planning and evaluation of the economic viability of the deposit.

The life - of - min e (LOM) plan provides for the extraction of 26.8 million tonnes of ore, 182.4 million 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 no minal production rate is estimated 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% Li 2 O and 13 3 ppm

Ta 2 O 5 , including dilution. The mill will process 1.61 million 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.
