EMP Metals Corp. has released highlights on Hub City Lithium Corp.’s (HCL) preliminary economic assessment (PEA) on the Viewfield lithium brine project, Saskatchewan. The PEA outlines the estimated production of battery-quality lithium carbonate equivalent (“lithium carbonate” or “LCE”) over a 23-year period, which represents an estimated a pre-tax internal rate of return (“IRR”) of 55% and a pre-tax net present value (“NPV”) of $1.49 billion USD, at an 8% discount rate.

Preliminary Economic Assessment Highlights

Pre-tax $1.49 billion USD NPV, at an 8% discount rate;

Pre-tax IRR of 55% which represents a payout duration of 2.1 years;

Total capital expenditures (“CAPEX”) of $571 million USD inclusive of both direct and indirect capital costs, including $52 million USD in contingency;

All-in operating costs (“OPEX”) of $3,319 USD per tonne LCE, $40 million USD annually, including all direct and indirect costs;

23-year project-life producing a total of 282,090 tonnes of battery-grade lithium carbonate, an average of 12,175 tonnes LCE per year;

Weighted average lithium concentrations of 128 mg/L from 7 target zones over the project life (range of 84 mg/L to 259 mg/L);

PEA encompasses approximately 11,000 net hectares, or 14% of Hub City Lithium’s lands in Southern Saskatchewan

Rob Gamley, EMP CEO, commented, “We are very pleased with the results of this Preliminary Economic Assessment. With payback in approximately two years, a 23-year project life and a pre-tax IRR of 55%, our Viewfield project is clearly a world class Lithium asset. The PEA study underpins a significant property value and highlights the benefits of excellent brine concentrations, low operating costs and close proximity to local infrastructure in one of the best mining jurisdictions in the world. The outstanding metrics demonstrated in the PEA represents a highly attractive scenario for EMP shareholders and supports the remarkable potential of this project as we quickly move to a commercial pilot.”

Project Development

The PEA encompasses 11,000 net hectares of land at Viewfield project area, representing 46% of Hub City Lithium’s Viewfield land holdings and only 14% of Hub City Lithium’s total land holdings in Southern Saskatchewan.

The development plan employed in the PEA has been broken into three distinct units:

Wellfield: includes all production wellbores, disposal wellbores and pipeline networks.

Direct Lithium Extraction (“DLE”): includes infrastructure related to pre-filtration and DLE operations. Koch Technology Solutions (“KTS”) was the DLE technical partner selected for the PEA.

Concentration, Refining and Conversion (“CRC”): includes all infrastructure downstream of DLE required to refine and convert lithium chloride eluent into battery grade LCE. Saltworks Technologies (“Saltworks”) was the CRC technical provider selected for the PEA.

Based on production testing and fluid analysis conducted by HCL in 2023 in the Viewfield project area, in addition to publicly available lithium testing throughout the area, it is expected to see lithium grades of 84 mg/L to 259 mg/L in the seven target members of the Duperow within the PEA lands. Over the life of the project, an average weighted concentration of 128 mg/L has been estimated.

Exploitation of the resource will occur in two production stages via multi-leg, horizontal wellbores. All project capital (minus end-of life capex) is allocated at the beginning of the project, with production estimated to commence in Q1 2027.

Stage 1: Wymark C, D and E (Years 1-7)

These zones are the shallowest and highest concentration (160 mg/L to 259 mg/L) zones and will be produced first through to depletion

Average LCE output during Stage 1 is 18,850 tonnes per year with average OPEX of $2,332 per tonne USD

Stage 2: Wymark A, B and Saskatoon A, B (Years 8 onward)

These zones are lower concentration (84 mg/l to 145 mg/L) and will be exploited after depletion of Wymark C, D and E

Average LCE output during Stage 2 is 10,200 tonnes per year with average OPEX of $4,166 per tonne USD

Note: A recovery factor of 50% of Total Lithium in Place was estimated for the PEA

A total of 36 multi-leg production wells will be drilled to exploit 7 target members of the Duperow, in addition to 30 vertical disposal wells to dispose of spent brine and process water. A network of underground pipelines will be constructed to transport the large water volumes from the wellheads to a DLE site for extraction and concentration to lithium chloride, and from there the eluent will be transported via pipelines to a CRC site for refining and conversion into battery-grade LCE. A total of five DLE sites and two CRC sites will process a daily average of 62,000 m3/day of brine, resulting in an average output of 12,175 tonnes per year of battery-grade LCE.

Lithium Pricing and Production

A detailed future pricing study for lithium carbonate was not completed for this PEA. A constant price of $20,000 USD per tonne of battery-grade lithium carbonate was chosen by reviewing publicly available pricing data and peer released economic assessments of similar lithium resources. Certain industry peers have used a constant price of $25,000 USD per tonne LCE in PEAs released over the last 12-months, however in-light of current global pricing for lithium, Hub City Lithium selected a base case of $20,000 per tonne with price sensitivities included at +/-20%.

Taxes and Royalties

The PEA outlines the taxes based on both the Canadian Federal Government and the Province of Saskatchewan. The Saskatchewan corporate income tax rate is 12 percent. The basic Canadian Federal Corporate tax rate is 38% of the Company’s income and 28% after federal tax abatement. After all tax holidays, the Company’s net federal tax rate is 15 Percent, with a total combined tax rate of 27 percent.

The majority of the Viewfield project area is on Crown land and is subject to Crown royalties. Within the Province of Saskatchewan, the Crown royalty rate is estimated at 3%, with a one-year royalty holiday for each facility hub. The balance of the Viewfield project area is subject to freehold royalties which commercial terms vary based on individual lease agreements.

Mineral Resource Estimate Incorporated into PEA

The following sets forth the total inferred resource incorporated into the PEA:

Viewfield Phase 1 Total inferred resource net to Hub City Lithium is 692,288 tonnes LCE

Concentrations in the 7 target zones of the Duperow range from 84 mg/L to 259 mg/L, with a weighted concentration of 128 mg/L

Wymark D tested 259 mg/L, the highest recorded concentration to date in Canada

Viewfield Project Area – Q1 2024 Field Pilot

Subsequent to the press release dated December 5, 2023, Hub City Lithium has completed its Treatability Study (“Study”) with Koch Technology Solutions, whereby 1,000 litres of feed brine from the Viewfield project area was tested for compatibility with KTS DLE technology. The Study was done in preparation for a DLE field pilot (one of the first in Canada) on the Hub City Lithium well that previously tested 258 mg/L of Lithium. The pilot, scheduled to begin in Q1 2024, will treat Viewfield brine and convert it into a highly concentrated lithium chloride eluent. It’s expected to run for 3 to 4 months and will operate 24/7, processing approximately 6,500 – 9,000 litres of feed brine per day.
