Athabasca-Style High-Grade Mineralization Discovered at RIB East Target

ATHA has discovered high-grade mineralization at the RIB East site, part of the 2025 Angilak Exploration Program. The discovery is the second new uranium deposit found during the program, within the Angikuni Basin along the 31 km RIB-Nine Iron Trend. Mineralization is defined by three drill holes, all intersecting shallow uranium mineralization, with a currently defined strike length of 400m.

ATHA Energy (OTCQB: SASKF) has announced a significant uranium discovery at its RIB East target within the 100%-owned Angilak Uranium Project in Nunavut. The company completed three successful drill holes that intersected shallow uranium mineralization, representing the second new discovery during the 2025 Angilak Exploration Program [1].

Key findings include high-grade mineralization in RIBE-DD-002 with a maximum radioactivity of 16,947 CPS, and RIBE-DD-003 showing continuous high-grade mineralization with a maximum radioactivity of 30,730 CPS. The mineralization is hosted within a graphitic structure, similar to uranium deposits in the Athabasca Basin [1].

The RIB East Discovery spans a 2-km long by 500m wide gravity anomaly with coincident conductors. The discovery is part of ATHA's broader 10,000m diamond drilling program along the 31km RIB-Nine Iron Trend, demonstrating the potential of the Angikuni Basin as an emerging uranium district [1].

Troy Boisjoli, CEO of ATHA Energy, commented on the discovery, stating, "The RIB East Discovery represents the second new discovery during the 2025 Angilak Exploration Program, beyond the Lac 50 Deposit Trend in the Angikuni Basin. These results continue to confirm the Company's exploration approach and thesis, while demonstrating our technical team's ability to execute and discover. The Company is thrilled with the fact that the RIB East Discovery has high-grade mineralization hosted within a graphitic structure - a known setting for mineralization in all major Athabasca Basin deposits and mines. We are at the early stages of understanding the potential of RIB East, with drilling covering just 400 m of a 2 km long anomaly. The early successes of the 2025 Angilak Exploration Program truly illustrate how underexplored and robust the mineralizing system is in the Angikuni Basin" [1].

Cliff Revering, VP Exploration at ATHA Energy, added, "The success of our first 3 holes in the RIB target area continues to demonstrate the effectiveness of our targeting strategy being employed at our Angilak Project. As well, with new discoveries at both the KU and RIB targets during our first exploration campaign along the 31 Km Rib-Nine Iron structural corridor, we remain confident in our view that the Angikuni Basin is an emerging uranium district and highly prospective for discovery of additional uranium deposits" [1].

The RIB East site is currently defined by a 2-km long by 500 m wide gravity anomaly with coincident NE to SW conductors. The site is located ~1.5 km within the Angikuni Basin and ~2 km to the northeast of the historic RIB Discovery [1].
