Press Release, Slave Lake Zinc Corp.: Significant Airborn Survey Completed Exploration Update

Vancouver, British Columbia--(Newsfile Corp. - April 28, 2021) - Slave Lake Zinc (CSE:SLZ) ("Slave Lake" or "the Company") has now completed the data acquisition phase of the planned detailed airborne geophysical survey at the Company's O'Connor Lake, NWT, exploration project.

The airborne magnetic and VLF EM survey was flown by the Company's contractor, Precision Geophysics, at a line spacing of 50 meters using a helicopter-based geophysical system. A total of 880 line kilometers was flown covering the property's structural control corridor.

Data processing and interpretation is underway with target recommendations for follow up ground-based exploration and drilling programs expected shortly.

Slave Lake Zinc's O'Connor Lake property has had significant historical exploration work completed by a developer in the early 1950's (as reported previously). At that time work included constructing a 45 kilometer winter access road, 62 drill holes totalling 4121 meters of core drilling and sinking of a three compartment shaft to 55 meters with a level established at 45 meters to access the vein. A 26.3 ton bulk sample sent to the Trail smelter graded 55.0% Pb, 13.5% Zn and 2.7 OPT Ag.

The Company is looking forward to sharing the compiled data with their "Collaboration Agreement" partners in the Northwest Territory Metis Nation in order to discuss its plans for further exploration at O'Connor Lake.

About Slave Lake Zinc

The property is located south of Great Slave Lake and to the east of Osisko Metals' Pine Point project.

Slave Lake Zinc Corp. believes that it is well positioned to advance this project and to expand significantly the historic potential of the property.
