ATHA drills high-grade zone 4km from Lac 50
ATHA Energy has outlined a new uranium discovery at Lac 50 Northwest at its Angilak Uranium Project in Nunavut, about 4km along strike from the Lac 50 deposit area. The result came from the first regional test along the Lac 50 Deposit Corridor in the 2026 Angilak Exploration programme.
Hole L50W-DD-002, the second drill hole at the discovery, intersected 11.5m of total composite uranium mineralisation across five zones from 305.0m to 479.9m. That interval included 7.0m of continuous mineralisation from 415.6m to 422.6m averaging 7,974 counts per second. Within that section, 1.6m returned high-grade mineralisation with maximum radioactivity of 40,162 counts per second.
Geologists described the mineralisation as basement-style and hosted in brecciated basalts. Quartz-carbonite veining fills the rock, while albite-hematite alteration halos and silicification overprint the host unit. ATHA compared the grade, width and style with Athabasca basement-style deposits.
At Lac 50 Northwest, drilling tested a 3D MMT inversion anomaly with a coincident broad gravity offset. As a result, L50W-DD-002 supports the prospectivity of the full 4km strike length between Lac 50 Northwest and the Lac 50 deposit area.
This find is the sixth regional discovery outside the Lac 50 deposit area in the past 15 months at Angilak. ATHA also reported a 100% success rate when using 3D EM inversion to target drilling across its 100%-owned Angilak Uranium Project.
Chief executive Troy Boisjoli said the latest hole shows both the scale of the Angilak system and the company’s ability to execute. He said the hit of high-grade uranium mineralisation 4km from the Lac 50 deposit area and the nearest drilling highlights the project’s unrealised potential.
Mineralized RIB Corridor results
Meanwhile, the discovery forms part of ATHA’s ongoing 2026 Angilak Exploration programme. The company expects to release additional preliminary drilling results from the Mineralized RIB Corridor following this first regional test along the Lac 50 Deposit Corridor.
Boisjoli also linked the exploration progress to projected growth in global energy demand and a larger role for nuclear power. According to his comments, supply stability from secure jurisdictions could strengthen the long-term case for Angilak.
Vice-president of exploration Cliff Revering described the result as a new high-grade mineralised zone more than 4km from the Lac 50 deposit area. In turn, the discovery expands the mineralised footprint along the corridor and gives ATHA another area to follow up in the current campaign.
