en.Wedoany.com Reported - Critical One Energy has released drilling results from the Howell Lake antimony-gold project in Ontario, Canada, revealing high-grade antimony mineralization and visual extensions of stibnite mineralization.
Located approximately 120 kilometers west of the "Ring of Fire" corridor, the project primarily reported assay results from drill holes HWL-2026-001, HWL-2026-002, and HWL-2026-007, while hole HWL-2026-016 provided only visual observations, all as part of the 2026 drilling campaign at Howell Lake.
The company reported that the seventh hole of the 2026 drilling program, located down-dip from hole six, intersected a 4.17-meter interval grading 27.35% antimony, including a 1.1-meter section with a high-grade grade of 70.3%. Additionally, holes one and two revealed near-surface antimony mineralization, with hole two recording a peak antimony grade of 3.1% at a depth of 26 meters over a thickness of 1.09 meters. The mineralization zone occurs within an intrusive chlorite-feldspar porphyry, which is connected to a northeast-trending structure in the region.
Visual assessment of hole sixteen indicated a 53.6-meter interval of massive stibnite, which remains open to the northeast. Geologically, the high-grade antimony cuts through the porphyry at a dip of approximately 55 degrees, while lower-grade zones are concentrated near the contact with graphitic tuff layers.
Critical One stated that further drilling is planned to expand the identified mineralization zone and test the continuity of massive stibnite, potentially providing a direct-shipping ore supply for North American buyers. Company founder, Executive Chairman, and CEO Duane Parnham noted that early drilling results confirm high-grade, continuous antimony mineralization extending well beyond historical resource boundaries, with these intercepts demonstrating grade continuity and thickness, highlighting the project's upside potential. He mentioned that the partnership with EFN will continue to assist Critical One in jointly evaluating the grade, scale, and strategic relevance of Howell Lake to meet antimony supply chain demands for Western energy security and defense sectors.
