Vancouver, British Columbia--(Newsfile Corp. - May 27, 2021) - Slave Lake Zinc (CSE: SLZ) ("Slave Lake" or "the Company") commenced its 2021 exploration season in April at the Company's O'Connor Lake property completing a gradient magnetic and VLF electromagnetic survey. The survey totalled over 880 line kilometers with the survey area centered over a historic exploration shaft developed in 1952. This helicopter based survey is the first exploration work of its kind conducted in this region. Application of this modern, state-of-the-art technology should help guide Slave Lake Zinc to identify additional headframe-type mineralization analogs should they exist within the project area.

Slave Lake Zinc has now received final data from the contractor. An initial examination indicates the survey has detected multiple northwest trending structures. These structures intersect favorable host rock lithologies and have created extensional fractures which may host the main zone mineralization which has been reported upon by the Company earlier.

Detailed analysis and compilation of the results has been undertaken by Aurora Geosciences of Yellowknife on behalf of the Company. This study is designed to define additional structures on the property that are similar to those hosting known mineralization. With the exciting results from the data processed to date, only approximately one third of the survey area has been analyzed, the Company is confident of developing additional exploration targets.

About Slave Lake Zinc

Slave Lake Zinc Corp. intends to develop the potential of its O'Connor Lake property, an historic zinc lead copper property located in the Northwest Territories of Canada. The property is located south of Great Slave Lake and to the east of Osisko Metals' Pine Point project. The property was initially developed after the Second World War and subsequently abandoned in 1952 when the prices of zinc and lead collapsed post war. Slave Lake Zinc Corp. believes that it is well positioned to advance this project and to expand significantly the historic potential of the property.
