EMP METALS ANNOUNCES SUCCESSFUL DLE PILOT PROJECT AND

PRODUCTION OF BATTERY GRADE LITHIUM CARBONATE; PROVIDES

UPDATE ON PEA

Vancouver, British Columbia, December 5, 2023 – EMP Metals Corp. (CSE: EMPS) (OTCQB:

EMPPF) (“EMP Metals” or the “Company ”) is pleased to report significant advancements and

milestones of its lithium project: (i) successful results from a direct lithium extraction (“DLE”) pilot

project, (ii) successful production of pure battery grade lithium carbonate, (iii) expected timing

of direct lithium extraction field pilot, (iv) increased acreage in core operating area, and (v)

update on the delivery of the Preliminary Economic Assessment (“PEA”).

Direct Lithium Extraction: Pilot Test Results

Hub City Lithium Corp. (“HCL”), a subsidiary company to EMP, has successfully completed a large-

scale pilot using the ILiAD DLE Platform developed by Energy Source Minerals (“ESM”), a privately

held process technology company focusing on Direct Lithium Extraction in North America. The

pilot, which processed 87,000 litres of brine from the Viewfield project area, successfully

recovered 8,300 litres of concentrated eluent with an average lithium concentration of 1,430

mg/L (representing a 7.5x concentration from the feed brine provided). An average lithium

recovery of >90% and an impurity rejection rate of 99.62% were also verified by ESM. HCL plans

to ship the highly concentr ated eluent to a 3 rd party for refinement into battery grade Lithium

Carbonate.

Production of Battery Grade Lithium Carbonate

HCL has confirmed successful production of 99.95% pure battery grade lithium carbonate

(Li2CO3), the Company’s first brine -to-battery-grade lithium carbonate production.

Saltworks Technologies Inc. (“Saltworks”), a global leader in designing and delivering industrial

wastewater treatment and lithium refinement solutions, saw brine sourced from wells in H CL’s

Viewfield project area refined into battery grade lithium carbonate. The Viewfield lithium -

containing brine represents the highest concentrations of lithium discovered in Canada to date

with minimal pretreatment requirements.

After DLE, the eluent was refined into battery -grade chemicals at Saltworks’ headquarters in

British Columbia. This work was executed with Saltworks’ proprietary concentrating, refining, and

converting technology and expert technical team, employing novel technolog y that lowers the

cost and greenhouse gas impact of lithium chemical production.

This project tested and de -risked the end -to-end flow sheet, resulting in multiple samples of

battery-grade lithium carbonate, which have been analyzed and validated by an independent 3rd

party laboratory. The captured data enables the acceleration of a full -scale plant design and

dispatch. Details below.

Rob Gamley, CEO of EMP Metals, commented “The results of our DLE to battery grade lithium

project exceeded expectations. Our partnership with Saltworks has proven to be a powerful

collaboration, setting the stage for future advancements in the Canadian lithium industry. This

achievement fuels our confidence in a dynamic future for all involved and the Canadian mineral

sector.”

Megan Low, Saltworks Technologies VP of Process Solutions Lithium & Industrial Water,

commented, “The Saltworks team is proud to continue to support EMP Metals and ROK

Resources to develop an important Canadian brine-to-battery chemicals project. We’ve been

impressed by EMP Metals’ methodical but rapid approach to take the right steps to de-risk their

project and merge commercial innovations into their flowsheet that improve economics and

scalability.”

Viewfield Field Pilot

Tel: 604-689-7422 208A - 980 West 1st Street, North Vancouver, BC V7P 3 N4

HCL is currently undergoing a Treatability Study (“Study”) with Koch Technology Solutions (“KTS”)

to test 1,000 litres of feed brine from the Viewfield project area. The Study is in preparation for

a DLE field pilot (one of the first in Saskatchewan) on the H CL 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 is 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.

Viewfield Acreage Purchase

At the November 2023 Crown Public Offering H CL increased its land holdings in its Viewfield

project area by 4,065 net acres (7% increase) to 59,000 net acres (23,900 hectares), for total

consideration of $1.17 million.

HCL now holds greater than 196,000 net acres (79,300 net hectares) of Subsurface Dispositions

and numerous strategic wellbores in Southern Saskatchewan.

Preliminary Economic Assessment Update

The PEA, which focuses on a Phase 1 development at Viewfield, is nearing completion with

anticipated final approvals and release in January 2024. The release delay can be attributed to

capital and operating cost adjustments within the PEA, a result of the ongoing Viewfield brine

testing and processing with multiple DLE vendors.

Lithium Brine Properties Joint Venture

The lithium brine properties consist of more than 196,000 net acres (79,300 net hectares) of

Subsurface Crown Mineral Dispositions in the Williston basin of Southern Saskatchewan.

EMP holds 75% of the joint venture with ROK Resources Inc. (ROK.V) holding the balance.
