Core Insights - enCore Energy Corp. has announced significant new uranium discoveries in areas near existing wellfields as part of a re-analysis of historic drill holes from the Alta Mesa In-Situ Recovery (ISR) Uranium Project [1][2] - The new roll fronts have been identified in at least three areas, with follow-up drilling ongoing to delineate these discoveries [1][3] Discovery Details - New roll front uranium mineralization has been found close to previously exploited areas, with one roll front advancing to permitting as Wellfield 3 Extension [2] - Two new roll fronts in Wellfield 4 have been discovered, each extending over 2,500 feet in length, located at a depth of 320 to 345 feet, which is nearly 200 feet above previously exploited mineralization [2] - The shallow depth of this mineralization allows for shorter drill times and significant cost savings in delineation and extraction compared to deeper mineralization [2] Drilling Program - The granular re-analysis of drill data is expected to continue through the end of 2025, with follow-up delineation drilling extending into 2026 [3] - A major drill program is set to commence soon on the recently acquired Alta Mesa East Property, which hosts extensions of roll front uranium mineralization [3] Historical Drilling Highlights - Current drilling highlights include several drill holes with varying depths and grades, with the highest grade recorded at 0.277% U3O8 over a thickness of 5.5 feet [4] - Historical drilling data shows previous grades and thicknesses, indicating the potential for further exploration and extraction [4] Project Overview - The Alta Mesa Uranium Project operates under a 70/30 joint venture with Boss Energy Limited and has a total operating capacity of 1.5 million pounds of uranium per year [7] - The project utilizes ISR technology for uranium extraction, which is a non-invasive process using natural groundwater and oxygen [8] - Historical production from the Alta Mesa CPP reached nearly 5 million pounds of uranium between 2005 and 2013 before being curtailed due to low prices [8] Company Background - enCore Energy Corp. is focused on providing clean, reliable, and affordable fuel for nuclear energy and is the only U.S. uranium company with multiple Central Processing Plants in operation [9] - The company is committed to working with local communities and indigenous governments to create positive impacts from its developments [10]
