Slave Lake Zinc Confirms High-Grade District Potential at O'Connor Lake; Assays Return Up to 7.75% Lead and 6.62% Zinc

About this update from Slave Lake Zinc Corp

Vancouver, British Columbia--(Newsfile Corp. - January 7, 2026) - Slave Lake Zinc Corp. (CSE: SLZ) ("the Company" or "SLZ") is pleased to announce encouraging geochemical results from its late 2025 geologic review at the O'Connor Lake exploration property in the South Slave area, Northwest Territories. The program has successfully validated the Company's regional exploration model, identifying high-grade mineralization in multiple new structures several kilometres distant from the historic Shaft Zone. Highlights of the 2025 Program: Program Overview and Geological Context During late September and early October 2025, Slave Lake Zinc contracted Aurora Geosciences Ltd. of Yellowknife to conduct a short 10-day geological reconnaissance program of the O'Connor Lake property. Operating from a float aircraft-supported tent camp, the field crew concentrated on evaluating historic showings along structural corridors located several kilometres from the historic "Shaft Zone." The results from this program help transform the Company's regional strategy into reality. The similarities in orientation and mineralogical character between these new discoveries and the original Shaft Zone vein strongly validate the hypothesis that the O'Connor Lake property hosts a regional-scale mineralizing system. The multi-element nature of the assays-highlighted by high-grade lead and zinc paired with significant copper and silver mineralization-points to a complex and fertile hydrothermal system capable of hosting substantial tonnage. CEO Commentary Ritch Wigham, CEO of Slave Lake Zinc, commented: "The results of this season's field program are a major step forward for the Company. We have successfully demonstrated that high-grade mineralization is not confined to the Shaft Zone but is part of a much larger, district-scale system. These results allow us to design a targeted exploration program to resolve the complex structural controls that localized this mineralization. By understanding the timing and orientation of these events, we can prioritize our most promising drill targets. Detailed structural mapping and geophysical surveying will now provide the critical data needed to unlock the full value of this property." Next Steps The Company is currently analyzing the findings of this successful program to define the nex...
