FUELING THE FUTURE

CORPUS CHRISTI, Texas

,

March 15, 2023

/CNW/ -

enCore Energy Corp.

("

enCore

" or the "

Company

") (NYSE American: EU) (TSXV: EU) announced today

that it has made a formal production decision for the resumption of uranium production from the Alta Mesa Processing Plant ("Alta Mesa" or "Plant) in early 2024.

Alta Mesa will be enCore's second producing location following resumption of uranium production at the South Texas Rosita Uranium Processing Plant ("Rosita")

scheduled for 2023.

Work underway at the Alta Mesa Processing Plant includes the construction of equipment staging areas and drill pads in the fully permitted Production

Authorization Area (PAA), planned for initial production due to its proximal location adjacent to the Plant. Development drilling, production and injection well

installation will start this month. Concurrently, enCore's technical staff are identifying equipment maintenance and limited repair needs at the Alta Mesa Processing

Plant involving the ion exchange system, uranium precipitation, drying and packaging circuits in order to restart production after having been on standby since

2013.

Alta Mesa Processing Plant and Project highlights include:

The Alta Mesa Processing Plant is enCore's third fully licensed production facility, along with Rosita and Kingsville Dome, all located in the business-friendly

state of

Texas

. There are only 11 licensed and constructed uranium production facilities in all of

the United States

(US);

The Alta Mesa Processing Plant can reach commercial production levels with limited required capital, from funds on hand, within an estimated 10 months of

today's announced production decision;

Advancing the Alta Mesa Processing Plant, in conjunction with planned production in 2023 at the Rosita Uranium Processing Plant, will cement enCore

Energy's position as the early leader in In-Situ Recovery (ISR) uranium production in the US;

Alta Mesa's operations are located on private land, with 100% of minerals privately owned, and in a supportive jurisdiction with primary regulatory authority

residing with the

State of Texas

;

The Alta Mesa Processing Plant utilizes well-known ISR technology to extract uranium in a non-invasive process through the use of natural groundwater and

oxygen, coupled with a proven ion exchange process, to recover the uranium.

Paul Goranson

, the Company's Chief Executive Officer said, "My previous experience includes building and successfully operating Alta Mesa. I am confident that

we have everything necessary within our control for a production restart, and enCore can quickly advance the project. The enCore team began initial assessment

work in

November 2022

, preparing for the start of work immediately following the closing of the acquisition of the Alta Mesa Processing Plant and Project. It is an

exciting time at enCore. Our 2023 startup of production at Rosita and now, the decision to proceed at Alta Mesa, will bring a reliable domestic low carbon energy

source to

South Texas

and

the United States

when it is most needed."

Alta Mesa Processing Plant and Project

The Alta Mesa project is a fully licensed and constructed ISR uranium project and central processing facility currently on standby, located on over 203,000 acres

of private land in the state of

Texas

. Total operating capacity is 1.5 million lbs U

(uranium) per year. Alta Mesa historically produced nearly 5 million lbs of

U

between 2005 and 2013, when full production was curtailed as a result of low uranium prices at the time.

The Company advises that it is not basing its production decisions at Alta Mesa or Rosita on a feasibility study of mineral reserves demonstrating economic and

technical viability. The production decision is based on known past In-Situ Recovery (ISR) and processing operations at these two production facilities and

surrounding lands. However, the Company understands that there is increased uncertainty, and consequently a higher risk of failure, when production is

undertaken in advance of a feasibility study. In addition, the mineral resource at Alta Mesa includes inferred resources which are considered too speculative

geologically to have economic considerations applied to them that would enable them to be categorized as mineral reserves. The Company has determined to

proceed with a production decision based on past operations at Alta Mesa and Rosita, including past ISR operations on the known mineral resource areas.

John M. Seeley

, Ph.D., P.G., C.P.G., enCore's Manager of Geology and Exploration, and a Qualified Person under NI 43-101, has reviewed and approved the

technical disclosure in this news release on behalf of enCore.

About enCore Energy Corp.

enCore Energy Corp. is committed to providing clean, reliable, and affordable domestic nuclear energy by becoming the next

United States

uranium producer in

2023. enCore solely utilizes In-Situ Recovery (ISR) for uranium extraction, a well-known and proven technology co-developed by the leaders at enCore Energy.

In-Situ Recovery extracts uranium in a non-invasive process through the use of natural groundwater and oxygen, coupled with a proven ion exchange process, to

recover the uranium. Uranium production is planned at enCore's licensed and past-producing South Texas Rosita Processing Plant in 2023, and at its licensed and

past-producing South Texas Alta Mesa Processing Plant in 2024. Future projects in enCore's production pipeline include the Dewey-Burdock project in

South

Dakota

and the Gas Hills project in

Wyoming

, along with significant uranium resource endowments in

New Mexico

providing long-term opportunities. The enCore

team is led by industry experts with extensive knowledge and experience in all aspects of ISR uranium operations and the nuclear fuel cycle. enCore diligently

works to realize value from other owned assets, including our proprietary uranium database that includes technical information from many past producing

companies, from our various non-core assets, and by leveraging our ISR expertise in researching opportunities that support the use of this technology as applied

to other metals. enCore is also committed to working with local communities and indigenous governments to create positive impact from corporate developments.
