A BOUT C RITICAL E LEMENTS C ORPORATION

A recent financial analysis (Technical Report and Preliminary Economic Assessment (PEA) 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% discou nt rate.

The payback period is estimated at 4.1 years. The pre - tax IRR is estimated at 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 prelimina ry 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 t hem to be

categorized as mineral reserves and there is no certainty that the preliminary 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% batt ery 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 .
