/CNW/ -

enCore Energy Corp.

("

enCore

" or the "

Company

") (TSXV: EU) (OTCQB: ENCUF) today announced the

completion and installation of all (five) baseline wells within the uranium mineralization at the 100%-owned, fully licensed Rosita Extension Project Production

Authorization Area (PAA) wellfield. In addition to establishing baseline conditions in the production area, the wells returned excellent uranium values with Grade

Thicknesses (GT*) ranging from 0.932 to 5.139. The Company also reports it has commenced installation of production well patterns (injection and extraction

wells) at the Rosita Extension PAA,

South Texas

as the initial source of uranium feed for the Rosita Central In-Situ Recovery (ISR) Uranium Processing Plant.

Highlights include:

Baseline Drill Hole BL-41 reported 22.0 feet of mineralization grading 0.234% U

3

O

8

from a depth of 184 feet;

In addition to an indication of grade of mineralization in the PAA, the baselines wells also serve to establish groundwater quality standards;

Commencement of installation of the production well patterns (injection and recovery wells) with 5 drill rigs are currently active at the Rosita Extension PAA

drilling;

Commencement of hydrologic and water quality testing of the baseline and monitor wells (see enCore news release dated

August 25, 2022

);

The Rosita Extension PAA is the first production area planned as a new source of uranium for the Rosita ISR Uranium Processing Plant;

The Rosita Extension PAA is located within the existing Radioactive Materials License, Underground Injection Control Permit and Aquifer Exemption areas at

the Rosita Project;

All intercepts are between 210 and 245 feet below surface in saturated sands (required for ISR). The water table is located approximately 95 - 115 feet below

surface.

*Grade Thickness, or GT, is defined as the product of the mineral grade (at the .02% U

cutoff) multiplied by the thickness of the mineralization at or above

the cutoff value. GT values of 0.3 and above are considered to be the minimum for inclusion in a wellfield. Values of 0.45 are considered typical ISR ore-grade

for shallow deposits.

Rosita Central Uranium Processing Plant (Rosita Plant)

enCore's Rosita Plant, located approximately 60 miles from

Corpus Christi, Texas

, is a licensed, past-producing in-situ recovery (ISR) uranium plant that is

completing refurbishment. The final stage of refurbishment work will be completed with the delivery of six pumps that have been delayed due to unexpected supply

chain interruptions. We remain on budget and the delay is not expected to impact scheduled production startup in 2023. The Rosita Plant is designed to process

uranium feed from multiple satellite operations, all located in the

South Texas

area, and is 1 of 11 licensed and constructed uranium processing plants in

the

United States

, 2 of which are owned by enCore Energy.

Quality Assurance/Quality Control

All drill holes are 5.625-inch diameter rotary-mud holes. Each hole is logged with electrical and gamma methods upon completion. Any anomalous gamma

readings are followed up with Prompt Fission Neutron (PFN) surveys which provide direct and accurate in-situ uranium values eliminating any concerns over

disequilibrium. The Company owns and operates 2 logging trucks and 5 PFN tools.

Many uranium deposits have a degree of disequilibrium, whereby the radioactivity measured in drill holes using traditional gamma methods does not accurately

correspond to ore grade, due to the continued decay of uranium daughter products including potassium, thorium, lead and bismuth relative to radium (Ra226), a

significant gamma emitter. Traditionally, accurate uranium values are therefore determined by chemical assay of drill core which is time consuming and expensive.

Without accurate uranium values, the potential for inaccurate estimates of mineralization on both the high and low side is ever present. Real-time PFN analysis

accurately eliminates potential errors by using neutron activation to directly detect and quantify uranium content in place down the drill hole.

The PFN tool creates very fast neutrons (14MeV) and fires 108 neutrons per second. Therefore, the neutrons emitted by the PFN tool excite, at an atomic level,

in-situ uranium atoms in the drill hole, creating fast (epithermal) neutrons and slow (thermal) neutrons. The ratio of epithermal to thermal neutrons is proportional to

uranium, allowing the U

O

ore grade to be accurately calculated. This provides a relatively inexpensive and instantaneous means for accurate assaying of in-situ

ore grades over large areas, and it allows for accurate ore body mapping, resource estimation, and wellfield planning.
