DALLAS, March 13, 2025 /PRNewswire/ - enCore Energy Corp. (NASDAQ:EU) (TSXV:EU) (the "Company" or "enCore"), America's Clean Energy CompanyTM, today announced the successful startup of its second Ion Exchange ("IX") Circuit at its South Texas Alta Mesa In-Situ Recovery ("ISR") Uranium Central Processing Plant ("Alta Mesa CPP"). IX Circuits collect uranium from process water pumped from recovery wells in the wellfield. This second IX Circuit at Alta Mesa doubles the total flow capacity from 2,500 gallons per minute ("GPM") to 5,000 GPM. Flow rate is an essential factor in expanding the amount of uranium captured.
In conjunction with the expansion of processing capacity, enCore has installed additional injection and extraction wells in the currently permitted and operational Wellfield 7 ("PAA-7"). The combination of the second IX Circuit and wellfield expansion utilizes approximately 75% of the current processing capacity. Additional wells will be brought online systematically in order to reach CPP capacity and increase the capture of uranium.
Executive Chairman, William M. Sheriff, stated: "At any given concentration of dissolved uranium in water, the more solution you pump, the more uranium that can be captured. At the Alta Mesa CPP, we have learned that our extraction process is faster than anticipated, which is expected to be positive for revenue and return on investment. The work on the second IX Circuit and additions to the wellfield have been underway for several months. While we are pleased to see the second IX Circuit operating, we look forward to full utilization of this increase in capacity. With additional drill rigs and accelerated effort, we look forward to steady advancement of our uranium capture rates."

Significant Highlights:
- The wellfield decline curve at Alta Mesa is quite steep, achieving approximately 80% uranium capture in just over 4 months. While total capture of uranium is comparable between most Wyoming ISR operations and Alta Mesa, the wellfield decline curve at other projects tends to be much flatter, taking 12 to 15 months for 80% recovery months due to differences in physical and chemical properties of the host rock and the process water;
- With this capture rate, enCore experiences a very quick recovery of uranium, however this necessitates an aggressive drilling and well completion schedule with an emphasis on logistics, urgency and oversight in the continued development and expansion of the wellfield;
- With the addition of the second IX Circuit, the Alta Mesa CPP now has a total flow capacity of 5,000 GPM, operating two of its three fully licensed IX Circuits at the Alta Mesa CPP;
- Work is underway for systematic and more aggressive expansion of Wellfield 7 with 22 drill rigs now operating on the Company's projects; 17 drill rigs are currently working on increasing uranium extraction at Alta Mesa. The drilling program has been expanding since year end and the Company is actively engaged in further increasing this number of drill rigs in the coming weeks and months;
- During the past six months, an additional 43 injection wells and 36 recovery wells have been added to Wellfield 7 feeding the second IX Circuit at the Alta Mesa CPP with a total flow rate of 1,450 GPM. Ongoing development of the wellfield to supply additional uranium bearing water to the second IX Circuit is continuing toward total circuit flow capacity with the addition of 13 injection wells and 13 recovery wells anticipated over the next 6 weeks;
- Work is underway to return Wellfield 6 ("PAA-6") to operation within the next 6 months. Wellfield 6 was in operation when Alta Mesa shut down in 2012/2013 with 370,000 lbs. of a Measured uranium ("U3O8") resource remaining1;
- There is currently 1 drill rig operating at the Upper Spring Creek Project where drilling will be completed in the next few days. The drill rig will be redeployed to Wellfield 7, bringing the total there to 18, after a short program at the Rosita Extension where a series of close space fences will delineate a portion of the wellfield that has not been exploited to date. Depending on the outcome, drilling of additional wells may be expected to come online within the next 3 to 4 months at the Rosita CPP;
- Construction and installation of the wellfield at the Upper Spring Creek Project will commence once the final permits have been received, this is expected before year end;
- A third IX Circuit is on site and recommissioning is planned for 2026. Once the third IX Circuit is online, it will bring processing capacity to 7,500 GPM, which will bring the Alta Mesa CPP to 100% of its IX capacity;
- An IX Circuit is similar to a water softener treatment which selectively removes hardness ions from water. Each IX Circuit at the Alta Mesa CPP contains four upflow columns and 2 downflow columns that contain the IX resin used to capture uranium from the produced water before it is recycled back into the wellfield, thereby minimizing the amount of water consumed in the ISR process.
About the Alta Mesa Uranium CPP and Wellfield
The Alta Mesa Project hosts a fully licensed and constructed ISR Central Processing Plant and operational wellfield located on 200,000+ acres of private land and mineral rights in and regulated by the state of Texas. Total operating capacity at the Alta Mesa CPP is 1.5 million lbs. U3O8 (uranium) per year with additional drying capacity of 0.5 million lbs. The Alta Mesa Project operates under a 70/30 joint venture with Boss Energy Limited ((ASX: BOE, OTCQX:BQSSF) that is managed by the Company.
The Alta Mesa CPP historically produced nearly 5 million lbs. of uranium between 2005 and 2013 when production was curtailed as a result of low prices. The Alta Mesa Project utilizes well known ISR technology to extract uranium in a non-invasive process using natural groundwater and oxygen. Currently, oxygenated water is being circulated in the wellfield through injection or extraction wells plumbed directly into the primary pipelines feeding the Alta Mesa CPP. Expansion of the wellfield will continue with production to steadily increase from the wellfield as expansion continues through 2025 and beyond.
