the exclusive right of Critical Elements to market and act as selling agent for any and all Lithium

products, including Lithium ore, concentrate and ch emical, resulting from the extraction and

production activities on the Property, including transformation into chemical products.

Nisk-1 Ni-Cu-PGE Deposit

Nisk is composed of two blocks totaling 90 claims covering an area of 45.9 km 2 and a length of over

20 km. The Route du Nord from Chibougamau runs inside the south border of the Property. Nisk-

1 is also traversed in a NE direction by a Hydro-Québec power line and a road that heads north to

the Eastmain River and beyond to the La Grande River area.

Figure 1: Property location

Nisk-1 is currently known for its magmatic nickel-c opper sulphide deposits associated with

ultramafic intrusion potential. It notably hosts the Nisk-1 Ni-Cu-PGE deposit.

Nisk-1 is hosted in an elongated body of serpentini zed ultramafic rocks that intrude the Lac des

Montagnes paragneiss and amphibolite sequence. The ultramafic rock intrusion is a sill bordered

by paragneisses and amphibolites. Quite similar on either side of the ultramafic sill, they still can

be subdivided into a lower paragneiss sequence to t he NW of the sill (stratigraphically older) and

an upper paragneiss sequence to the SE of the sill (stratigraphically younger).

The ultramafic sill is not a single intrusion. At l east two distinct lithological units can be identif ied.

The first, a grey serpentinized peridotite with mag netite veinlets, does not contain any sulphide

minerals. The second is a black serpentinized peridotite .The Ni-Cu-Co-Fe sulphide mineralization

is invariably associated with this black serpentinite.

Nisk-1 is the only mineralized zone with estimated resources on the property. An NI 43-101

resource estimate was delivered in 2009. (The resource estimation was completed by RSW INC.

by Pierre Trudel Ph.D., P.Eng. and is detailed in th eir report entitled Resource Estimate for the

NISK-1 Deposit, Lac Levac Property, Nemiscau, Quebe c, dated December 2009. The 2009

resource estimation is considered to be a "Historical Estimate" as defined by National Instrument

43-101 Standards of disclosure for mineral projects):

 Measured resource: 1,255,000 tonnes at 1.09% Ni; 0 .56% Cu; 0.07% Co; 1.11 g/t Pd and

0.20 g/t Pt

 Indicated resource: 783,000 tonnes at 1.00% Ni; 0.53% Cu; 0.06% Co; 0.91 g/t Pd and 0.29

g/t Pt

 Inferred resource: 1,053,000 tonnes at 0.81% Ni; 0.32% Cu; 0.06% Co; 1.06 g/t Pd and 0.50

g/t Pt

ABOUT CRITICAL ELEMENTS LITHIUM CORPORATION

Primero Group recently completed the first phase of its Early Contractor Involvement agreement

with the Corporation and provided a Guaranteed Maximum Price for the engineering, procurement

and construction of the wholly-owned Rose Lithium-Tantalum project on a lump sum turnkey basis

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

study is based on price forecasts of US $750/tonne f or chemical-grade lithium concentrate (5%

Li2O), US $1,500/tonne for technical-grade lithium con centrate (6% Li 2O) 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.
