/CNW/ -

enCore Energy Corp.

(NYSE American: EU) (TSXV: EU) (the "

Company

" or "

enCore"

) today provides an update from the

South Texas Alta Mesa In-Situ Recovery (ISR) Uranium Central Processing Plant (CPP) and Wellfield. Upgrades and refurbishments continue to advance on

schedule for the planned 2024 resumption of uranium production

1

. The Company also announces continuing positive results from the wellfield delineation drill

program. Further, planned production for the Rosita CPP continues to advance as projected.

At the Alta Mesa CPP, enCore continues work on the refurbishment of the processing circuits. The elution circuit, used to strip uranium from the ion exchange

beads, has been completed, and represents a significant milestone in the pathway for production restart. All of the process pumps for the startup IX circuit have

been rebuilt and replaced, including the main injection pumps. We anticipate completing the refurbishment of the startup portion of the IX circuit before the end of

2023.

The yellowcake processing circuit refurbishment has started with the rebuilding of key components of the yellowcake storage systems and ordering of long lead

time items such as the filter press and yellowcake transfer pumps. Refurbishment work commenced on the yellowcake drying system, and that work is expected

to be completed just prior to the anticipated production restart date.

Within Production Authorization Area 7 (PAA-7), enCore is installing injection and production wells in the wellfield and has received and staged the equipment to

install the pipelines to connect the wellfield to the Alta Mesa CPP. All of the necessary equipment for the start-up of production in the PAA-7 wellfield has been

received or has been ordered with a confirmed delivery schedule.

Paul Goranson

, enCore's Chief Executive Officer stated "The uranium spot market is presenting prices that have not been seen since prior to 2011. The driving

force for the market is increased demand as supply continues to be constrained, principally due to uranium supply chain challenges created by geopolitical

conditions and the projected rapid increase in demand for uranium and nuclear power. At enCore, we are leveraging our experience and resources toward the

restart of the Alta Mesa CPP to become a domestic solution to the global uranium demand needs. I am pleased with the progress at Alta Mesa, we are continuing

to build a competent team to get the Project to production and look forward to expansion."

There are currently six (6) drill rigs in full operation at the Alta Mesa CPP and Wellfield, with contracts pending for three (3) additional rigs. The wellfield drilling

operations, delineating the roll front mineralization within PAA-7, which commenced in

March 2023

, are advancing rapidly with 92 holes drilled since the previous

update (

September 5, 2023

). In total, 367 drill holes have been completed through

November 17

, 2023.

Further refined delineation drilling within the PAA-7 continues to establish the exact pattern of injection and recovery wells from which to maximize production

efficiency. To date, eighty-six (86) holes have been cased with seventeen (17) holes completed. Two (2) drill rigs are currently casing with one (1) drill rig focused

on completion activities. An additional drill rig will be moving to completion activities in the coming weeks.

Alta Mesa In-Situ Recovery (ISR) Uranium Central Processing Plant ("Alta Mesa CPP") & Wellfield

The Alta Mesa CPP and Wellfield hosts a fully licensed and constructed ISR uranium plant, located on 200,000+ acres of private land in the state of

Texas

. Alta

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

("Rosita") scheduled for 2023.

Total operating capacity at the Alta Mesa CPP is 1.5 million lbs. U

(uranium) per year. The Alta Mesa CPP historically produced nearly 5 million lbs. U

O

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

Alta Mesa CPP and Wellfield highlights:

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

state of

Texas

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

the United States

(US);

Advancing the Alta Mesa CPP, in conjunction with planned production in 2023 at the Rosita CPP, will cement enCore Energy's position as the early leader in

In-Situ Recovery (ISR) uranium production in

the United States

;

Alta Mesa CPP'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 CPP utilizes well-known ISR technology to extract uranium in a non-invasive process using natural groundwater and oxygen, coupled with a

proven ion exchange process, to recover the uranium.

NI-43-101 Technical Report Summary for the Alta

Mesa Uranium Project, Brooks and Jim Hogg Counties, Texas, USA completed by Doug Beahm, PE, PG, of BRS Engineering. (Effective January 19, 2023)

.

The Company advises that it is not basing its production decisions at Alta Mesa CPP or Rosita CPP 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. The Company has determined to proceed with a production decision based on past operations at the Alta Mesa

CPP and Rosita CPP, including past ISR operations in 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 the Company.

The Company also advises that Mr.

Gregory Zerzan

has resigned his position with the Company. The Company thanks Mr. Zerzan for his service and wishes him

well in his future endeavors.
