en.Wedoany.com Reported - Critical One Energy Inc. has received new assay results from drill hole HWL-2026-006 at the Howells Lake Antimony-Gold Project, showing that the lower antimony mineralization zone extends further at depth. The project is located approximately 120 kilometers west of the "Ring of Fire" corridor in Ontario, Canada.

The new assays returned 15.3 meters grading 1.76% antimony from 114.7 meters to 130 meters downhole, extending the lower antimony mineralization zone previously announced by the company on May 15, 2026. The drill hole also identified associated gold and zinc mineralization, with gold grades up to 1.17 g/t and zinc grades of 0.54%, along with anomalous antimony over a 3-meter interval, supporting the interpretation that the East Zone may represent part of a broader, vertically extensive antimony-gold mineralized system.

Previously released assays from hole 6 identified massive stibnite over an 8-meter interval grading 42.2% antimony, including a 4-meter interval grading 70.2% antimony. Antimony mineralization in hole 6 now extends from 79 meters to 130 meters downhole, supporting the company's interpretation that the East Zone remains open at depth.

To date, 18 drill holes totaling approximately 4,000 meters have been completed at the project. The company has finalized a budget to support drilling through December 2026, targeting 20,000 meters.

Duane Parnham, Founder, Executive Chairman, and CEO of Critical One, stated that hole 6 continues to provide evidence of high-grade, large-scale antimony mineralization at the Howells Lake project. The expansion of the lower antimony mineralization zone, along with associated gold and zinc mineralization, provides justification for further exploration of the polymetallic potential.

On the operational side, the company is optimizing site logistics, core handling, and sample submission to shorten the cycle from drilling to disclosure. New assay results will be integrated with core observations and the geophysical model announced on December 2, 2025, to prioritize subsequent drilling.

Samples were analyzed at AGAT Laboratories in Thunder Bay, Ontario. Gold was determined by fire assay using a 50-gram sample with ICP-OES finish, while antimony and 30 other elements were determined by sodium peroxide fusion and ICP-OES. Overlimit antimony samples were re-analyzed semi-quantitatively by wavelength dispersive XRF. AGAT Laboratories is an internationally accredited laboratory.
