ENCORE ENERGY PROVIDES ALTA MESA ISR URANIUM CENTRAL PROCESSING PLANT UPDATE AND NEW DISCOVERY

EnCore Energy Corp.'s South Texas Alta Mesa in situ recovery (ISR) uranium central processing plant upgrades and refurbishments are ahead of schedule and under budget. This follows the previously announced (EnCore news release -- March 15, 2023) formal production decision for the resumption of uranium production in early 2024. The company has also released continuing positive results from the wellfield delineation drill program and a newly discovered mineralized zone at the Alta Mesa wellfield.

Presently there are six drill rigs working at Alta Mesa with a seventh rig to be added shortly. The wellfield drilling operations, within production authorization area 7 (PAA), which commenced in March, 2023, are advancing rapidly with 81 holes drilled to date with drilling delineating the roll front mineralization within PAA-7. The Middle C unit, a productive sand, essential for ISR, in PAA-3 was not previously known to be mineralized under PAA-7. The drilling program has encountered unexpected significant grade in the Middle C unit underlying PAA-7, with grade thicknesses multiplied by the thickness of the mineralization at or above the cut-off value ranging from 0.481 to 1.888 in four of the holes. Further drilling along trend will continue to delineate this new mineralized sand and is likely to increase the overall mineralization within PAA-7.

Of these holes, 14 are being cased as injection wells and 14 as recovery wells while further refined delineation drilling within the PAA continues to establish the exact pattern of injection and recovery wells from which to maximize production efficiency.

The Alta Mesa central processing plant (CPP) is advancing toward a restart of production and presently completing minor scheduled renovations with equipment upgrades and refurbishments under way. A thorough equipment evaluation determined 90 per cent of the piping and valves are operational with limited maintenance requirements. Of 40 pumps and motors evaluated, including major pumps, 30 are being rebuilt and refurbished on site, mitigating some supply chain risks. Longer lead time items now ordered are not critical for initial plant production start-up.

Alta Mesa in situ recovery uranium central processing plant and project

The Alta Mesa CPP and project is a fully licensed and constructed ISR uranium project and CPP currently on standby, located on over 200,000 acres of private land in the state of Texas. Alta Mesa will be EnCore's second producing location following resumption of uranium production at the South Texas Rosita uranium processing plant scheduled for 2023.

Total operating capacity is 1.5 million pounds U3O8 (triuranium octoxide) per year. Alta Mesa historically produced nearly five million lb of U3O8 between 2005 and 2013, when full production was curtailed as a result of low uranium prices at the time.

Alta Mesa processing plant and project highlights include:

• The Alta Mesa CPP is EnCore's third fully licensed production facility, along with Rosita and Kingsville Dome CPPs, 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.
• The Alta Mesa processing plant can reach commercial production levels with limited required capital, from funds on hand, within an estimated 10 months of announced production decision.
• 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 ISR uranium production in the U.S.
• Alta Mesa's operations are located on private land, with 100 per cent 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 using natural groundwater and oxygen, coupled with a proven ion exchange process, to recover the uranium.

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 in the known mineral resource areas.

Year-end financial statements

The company also announces that its annual information form, consolidated annual financial statements, and management's discussion and analysis for the year ended Dec. 31, 2022, have been filed with Canadian securities regulatory authorities. EnCore has also filed its annual report on Form 40-F for the year ended Dec. 31, 2022, with the U.S. Securities and Exchange Commission. Copies of these documents may be obtained on SEDAR, EDGAR (for the Form 40-F) or EnCore's website.

Shareholders may also receive a hard copy of these documents without charge upon request to EnCore Energy, 1200-750 W. Pender St., Vancouver, B.C., V6C 2T8, or to info@EnCoreuranium.com.

Stock option grant

The company also announces that it has granted incentive stock options to certain of its directors, officers and related party consultants to purchase an aggregate of up to 2,075,000 common shares in the capital of the company at a price of $2.79 per share for a five-year period, in accordance with its stock option plan. Vesting will occur over a period of 24 months, with an initial 25 per cent of the options vesting six months following the date of grant, followed by an additional 25 per cent of the options every six months thereafter until fully vested.

About EnCore Energy Corp.

EnCore Energy 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 using 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 its proprietary uranium database that includes technical information from many past-producing companies, from its various non-core assets and by leveraging its 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.

We seek Safe Harbor.
