Critical Elements Lithium Announces Appointment of Mr. Michel Clément, P.Eng., PMP as Senior Project Control Director

Overview

Critical Elements Lithium Corporation's (TSXV:CRE,OTCQX:CRECF,FWB:F12) vision is to be a large, responsible supplier of lithium hydroxide to the emerging electric vehicle and energy storage industries. The company is well-positioned, wholly owning over 850 km² of prospective lands hosting one of the highest purity spodumene deposits globally. This deposit is in Quebec, one of the company's premier mining investment jurisdictions. The company aspires to achieve its goals with a minimal environmental footprint by drawing electricity from Quebec's established low-carbon power grid and in cooperation with the Cree Nation communities, with whom relationships have been formalized.

The Rose lithium-tantalum deposit, a high-purity lithium deposit, can supply multiple lithium markets because of its unique purity with low iron oxide and mica content. The Rose lithium-tantalum deposit has an updated NI 43-101 resource estimate that outlines an indicated resource of 31.9 million tonnes grading 1.04 percent lithium oxide equivalent or 0.93 percent lithium oxide and 148 ppm of tantalum pentoxide, with an inferred resource of 2.8 million tonnes grading 0.92 percent lithium oxide equivalent or 0.82 percent lithium oxide and 145 ppm of tantalum pentoxide. Positive feasibility study also showed 17 years of mine life with an average production of 173,317 tonnes of chemical grade 5.5 percent spodumene concentrate; 51,369 tonnes of technical grade 6.0 percent spodumene concentrate; and 441 tonnes of tantalum concentrate from year two up to year 16.

Following a positive feasibility study for spodumene mining and concentration, Critical Elements Lithium Corporation is now ready to advance to the next stage of development for Rose. The feasibility study was, in part, informed by the results of a bulk sampling and pilot plant study. The results demonstrated that the conversion of the resources from the Rose lithium-tantalum deposit into the spodumene crystalline phase is easily achievable, with lithium concentrate grades up to 6.56 percent.

Most recent testing at the Rose lithium-tantalum pilot plant has resulted in the production of battery-quality lithium hydroxide. Critical Elements was able to demonstrate that its plant can achieve extraction rates of 93 percent, which is higher than the market benchmark of 70 percent to 75 percent. The plant's overall recovery rate from spodumene to battery-quality lithium hydroxide is 80 percent, which is again higher than the market benchmark of 65 percent.

Tantalum is used in a wide variety of applications across the electronics, medicine, engineering and energy-generation industries. Since 1995, the market for tantalum has experienced average yearly growth in demand of about 8 to 12 percent. End users are facing increasing market pressure to secure conflict-free sources of tantalum, further tightening global supply.

Key Project

Rose Lithium-Tantalum Project

The Rose lithium-tantalum project is located in the James Bay area of Quebec, Canada, about 35 kilometres north of Nemiscau and 75 kilometres due south of Newmont Corporation's (NYSE:NEM) Eleonore gold deposit. Excellent infrastructure is in place locally and regionally, including a 100-ton capacity road access, an airport, and a power line directly on the project property.

Rose is located in the Quebec Plan Nord designated area, where the government is fast-tracking the construction of new infrastructure, accelerating permitting and assisting with project financing. The project covers about 245 square miles of active mining titles in the northeastern part of the Archean Superior Province of the Canadian Shield craton and within the southern portion of the Middle and Lower Eastmain greenstone belt.

Resource Estimate

The Rose deposit has an updated NI 43-101 outlining an indicated resource of 31.9 million tonnes grading 1.04 percent lithium oxide equivalent or 0.93 percent lithium oxide and 148 ppm of tantalum pentoxide with an inferred resource of 2.8 million tonnes grading 0.92 percent lithium oxide equivalent or 0.82 percent lithium oxide and 145 ppm of tantalum pentoxide.

Feasibility Study

On June 13, 2022, the company announced the results of a new feasibility study on the Rose Lithium-Tantalum project in Eeyou-Istchee – James Bay, Québec, which includes after-tax NPV of US$1.915 million at 8 percent discount rate, and after-tax IRR of 82.4 percent. Highlights of the feasibility study include:

Critical Elements consistently advances the Rose Lithium-Tantalum Project in a low-risk manner. The new feasibility study incorporates a standard truck and shovel open-pit mining operation and conventional lithium processing technologies. The project is expected to produce technical grade spodumene concentrate for the glass and ceramics industry and chemical grade spodumene concentrate for conversion for use in batteries for e-mobility, as well as a tantalite concentrate.

Excellent recoveries and battery-grade purity

Intensive metallurgical testing and flowsheet optimization work have shown that Critical Elements Lithium Corporation's Rose lithium-tantalum project demonstrates a significant advantage over other known lithium deposits based on its ability to produce premium-purity lithium carbonate at a low cost.

During flotation testing, recoveries reached up to 91.9 percent lithium with a concentration grade of 6.43 percent lithium; recoveries averaged 90.88 percent with a concentration grade of 6.2 percent lithium.

In April 2017, Critical Elements Lithium Corporation announced the successful completion of its pilot work with results in spodumene concentrates grading up to 6.56 percent lithium. From Rose, recovery rates averaged 83.4 percent with a concentrate grade of 6.41 percent, and from Rose South, recovery rates averaged 81.9 percent with a concentrate grade of 6.56 percent.

In May 2022, Critical Elements Lithium announced results from a recently completed pilot test program at the Metso Outotec Research Center, successfully converting spodumene concentrate from the Rose Project into battery-grade lithium hydroxide using a thermal leaching process.

The pilot plant conversion process from spodumene concentrate to lithium hydroxide was further optimized and confirmed the previous strong results with extraction and conversion rates of 92 percent. In addition, the pilot plant produced battery-grade lithium hydroxide.

The two critical steps of the process to recover the lithium from spodumene are the conversion from alpha spodumene to beta spodumene where the piloting work achieved 98 percent conversion rate and the separation of the lithium hydroxide from the calcined spodumene by soda-leaching (98 percent efficiency) and conversion to lithium hydroxide (96 percent efficiency).

• Battery-grade lithium hydroxide with a further improved quality profile
• High spodumene alpha/beta conversion / leaching / conversion rates of combined 92 percent
  • Efficiency for the calcination 98 percent
  • Efficiency for the soda-leaching 98 percent
  • Efficiency for the lithium hydroxide conversion 96 percent

Successful results using a thermal leaching process demonstrate that Critical Elements can deliver a battery-grade lithium hydroxide to the electric vehicle market. Additional tests may need to be conducted by the Corporation in order to meet customer specific requirements.

To date, Critical Elements has completed the following testing and piloting work:

• Piloting of the chosen concentrator plant design (see Critical Elements press release dated April 5, 2017).
• Piloting of the thermal conversion of the ore from α-spodumene to β-spodumene (See Critical Elements press release dated April 13, 2017).
• Piloting of the Thermal Leaching Process + bicarbonization for lithium carbonate (See Critical Elements press release dated May 29, 2017).
• Piloting of the Thermal Leaching + Lime Process to produce lithium hydroxide (See Critical Elements press release dated October 29, 2018).

Tantalum by-product more economical than potash

The Rose lithium-tantalum deposit, however, possesses a unique combination of tantalum and lithium mineralization. The tantalum found in the Rose lithium-tantalum deposit gives the project additional by-product diversification and makes it one of the few economic, conflict-free, industrial-scale tantalum sources in the world.
