Slave Lake Zinc Update

Vancouver, British Columbia--(Newsfile Corp. - December 20, 2023) - Slave Lake Zinc Corp. (CSE: SLZ) (the "Company") recently acquired additional historical information dating from the 1950s on the Company's large-scale O'Connor Lake high-grade Critical Metals zinc-lead property. The Company continuously updates its database as new information becomes available. As a result, several highly prospective new areas have been outlined that will form part of next season's fieldwork. These new targets lie within the Company's main structural corridor centered over the MWK Headframe Deposit. These newly acquired results are summarized in the company's update (https://zinccorp.ca/wp-content/uploads/2023/12/SLZ-Opportunity.pdf).

The new information from a 1952 trench, documents mineralization within the MCO structure, which occurs 7 kilometers west of the Headframe Deposit and returned a trench assay of 0.97 ounces of gold per ton, 21% lead, 6.7% zinc and 1.2 ounces of silver per ton. Another historical sample at MCO from 1965 assayed 11.6 ounces of silver per ton, 0.40% lead and 1.1% zinc. This result indicates silver may occur in its natural state or as distinct silver minerals. Historic 1952 sampling at the BSM claims, approximately 5 kilometers northwest of the Headframe Deposit, reported a trench sample assaying 0.88 ounces of gold per ton,4.2% lead and 19.4% zinc. These new targets lie along strike of the main deposit structures. Lakes or swamps cover most of the intervening area. These are historic results and require verification.

The nature of the base metal mineralization is considered to be from a common, deep-seated hydrothermal source. The distribution of the precious metal showings indicates the possibility of regional-scale depositional zoning, a prospecting tool overlooked by the early zinc-lead explorers.

During the 2023 field season forest fires forced the closure of much of the NWT and prevented Slave Lake, and all other regional explorers, from accessing their project. The Company looks forward to detailed field work for the 2024 exploration season including the verification of these historic results and expanding the known resource by drilling priority targets at O-Connor Lake. Mr. Gary Vivian, P. Geol and Qualified Person, of Aurora Geosciences, has reviewed the contents of this release.

Slave Lake CEO Ritch Wigham commented, "The Company continues to integrate historic information and expand our database. We intend to systematically pursue our inventory of highly prospective exploration targets. The application of modern exploration techniques will be used to evaluate the historical showings and new "yet-to-be-discovered" targets. The O'Connor Lake land package is under-explored. The Company is working toward a drill plan for late 2024, or early 2025."
