(NASDAQ: EU) (TSXV: EU) (the "Company" or "enCore"), America's Clean Energy Company TM , reports positive results from the ongoing drilling program at the Alta Mesa East Project, located immediately adjacent to the established Alta Mesa Wellfields and Central Processing Plant in South Texas. The Alta Mesa East Project drilling program targets the continuation of productive roll fronts from several Alta Mesa Wellfields. Alta Mesa East Project Drilling Highlights Drill hole number 12-20 intersected 8.5 feet of mineralization grading 0.199% U 3 O 8 , for a Grade Thickness ("GT") of 1.69, from a depth of 487 feet.    The Company considers a GT value of 0.3 as being suitable for inclusion in a wellfield; The latest results include 20 drill holes, of which 12 were found to be mineralized (see June 1, 2026, news release for initial results); Six of the ten drill holes have returned GT values ranging from 0.43 to 1.76; The ongoing drill program has discovered uranium mineralization within sands at an average depth between 400 and 460 feet, and within sands between 480 and 520 feet; The drill program continues to make excellent progress with six rigs typically drilling on 400 to 500 foot spacing with an average depth of 600 feet; Seven widely spaced east-west fences of drilling are underway to generally characterize the mineralization across the entire property.

Our aggressive exploratory drilling program continues to provide results that support our thesis," William M. Sheriff
