Highlights include:

Murphy Lake South (17,676 acres) is strategically located adjacent to the LaRocque Lake Conductive Corridor—host to IsoEnergy's high-grade Hurricane Deposit
Previous drilling by Denison Mines has identified anomalous uranium and pathfinder elements, highlighting the potential for a meaningful new discovery.
Exploration permit covers ground geophysics, surface sampling, and up to 30 drill holes

VANCOUVER, British Columbia, June 05, 2025 (GLOBE NEWSWIRE) -- Foremost Clean Energy Ltd. (NASDAQ:FMST) (CSE:FAT) ("Foremost" or the "Company") is pleased to announce the receipt of a three-year exploration permit from the Saskatchewan Ministry of Environment for the Murphy Lake South Property ("Murphy"), located in the world-renowned Athabasca Basin region of northern Saskatchewan. The permit, valid until December 31, 2027, allows the Company to conduct mineral exploration activities including geochemical surveys, geophysics, and drilling of up to 30 holes. Foremost is currently planning the final details of a fully-funded summer drill program.

Jason Barnard, Foremost's President and CEO states "The receipt of this permit is exceptionally well-timed. Murphy is strategically positioned within and alongside the LaRocque Lake Conductive Corridor that hosts the high-grade Hurricane Deposit. Our property shares several geological characteristics with those found at Hurricane, including graphitic basement structures and shallow depth to the unconformity. Historical drilling at Murphy between 2008 and 2017 has already intersected anomalous uranium and pathfinder elements, which are indicative of a potentially significant mineralizing system. With this permit in hand, and significant historic exploration information obtained from previous work completed on the property by Denison Mines Corp. (("Denison", NYSE:DNN), we are in an enviable position where we are finalizing plans for a summer drill program with several exciting discovery-ready drill targets."

Mr. Barnard continues "We are also pleased to have David Cates, President & CEO of Denison, join us for today's webinar as we update the market on our exploration progress and strategic collaboration. Together, we will detail our plans to develop and drive growth on this prospective uranium portfolio, as well as provide investors a unique opportunity to engage with us directly during the live Q&A session."

Murphy is comprised of 6 mineral claims totaling 17,676 acres / 7,153 hectares, located approximately 30 kilometers northwest of the McClean Lake mill (see figure 1 below) towards the eastern edge of the Athabasca Basin region in northern Saskatchewan. The property is proximal to the La Rocque Lake Conductive corridor, which is host to multiple occurrences of high-grade uranium mineralization, including the Alligator zone, Larocque Lake Zone, and IsoEnergy's Hurricane Deposit, which is amongst the world's highest grade uranium deposits with estimated Indicated Mineral Resources of 48.6M lbs U₃O₈ from 63,800 tonnes at an average grade of 34.5% U₃O₈¹

Murphy is considered highly prospective due to its geological setting, which shares several similarities with the geological conditions present in proximity to the Hurricane Deposit. Notably, the property is highlighted by the following features:

Proximity to the LaRocque Conductive Corridor: A major conductive trend of graphitic rocks known to host complex structure and control high-grade uranium mineralization.
Shallow Unconformity: The interface between the sandstone and basement rocks is relatively shallow (approximately 200 - 350 metres depth), making it cost-effective to drill.
Mineralization: A mineralized system has already been identified on the property, with 400 metres of strike length open in both the east and west directions.
- Drilling in 2015 (MP-15-03²) intersected 0.25% U₃O₈ over 6 metres
- Drilling in 2008 (MP-08-01³) intersected 618 ppm U and 757 ppm U in two 20-centimeter zones.
- Weak mineralization intersected in 2016, averaging 0.03% U₃O₈ over 22.5 metres from 255 metres to 277.5 metres in MP-16-17⁴.
- Drill results immediately above the unconformity in 2016 (MP-16-11) intersected 0.13% U₃O₈ over 12.5 metres.

Alteration: The elevated uranium assays are paired with anomalous pathfinder elements, fault structures, and strong alteration indicating classic unconformity-style mineralization in a significant hydrothermal system.
Untested Basement Potential: Historical drilling on the property primarily targeted mineralization at or near the unconformity. Strong potential for mineralization exists in the faulted basement rocks.
Offset Unconformity: Up to 96 metres of vertical displacement of the unconformity has been identified at Murphy. Basement wedges are a common feature of significant uranium deposits and are considered prime targets for further exploration.
Conductive Trends On-Property: Ground geophysics has identified conductive packages that are thought to represent graphitic metasediments, prime targets for uranium mineralization.

Planned Exploration Program

Foremost is planning a two-phase drill program to test high-priority targets:

Phase 1 Drilling (Summer 2025): Approximately 1,500 meters of diamond drilling targeting the unconformity and underlying basement rocks along semi-brittle graphitic faults. These targets were identified from historical drilling and geophysical surveys, where anomalous uranium and pathfinder elements were detected.
Phase 2 Drilling (Winter 2025/2026): Follow-up drilling to test geophysical anomalies (including electromagnetic conductors) and any targets generated from Phase 1 results. This phase will focus on identifying brittle structures and graphitic horizons with associated clay alteration, which are typical hosts for high-grade uranium in the Athabasca Basin.

The combination of strategic location, under-explored basement potential, and systematic geological indicators makes Murphy a high-priority project within Foremost's 10-project uranium exploration portfolio.
