Mistango Announces 5,000 Metre Phase 2 Drill Program at the Kirkland West Gold Project

TORONTO, Oct. 4, 2021 - Mistango River Resources Inc. ("Mistango" or the "Company") (CSE: MIS) is pleased announce the start of a Phase 2 drilling program at its 100%-owned Kirkland West Gold Project, adjacent to Kirkland Lake Gold's Macassa Mine near Kirkland Lake, Ontario. The Company has engaged a drilling contractor and the drilling program is planned to begin on or around the second week of October, 2021.

The Phase 2 program in the Baldwin Zone will include 5,000 metres of drilling and is designed to test exploration targets hosted by geological and structural environments that are determined to be highly prospective based on comparison with gold deposits in the adjacent Kirkland Lake mining camp such as the Macassa mine that is located a few thousand metres to the East of the Baldwin Zone. New interpretations of geological and structural environments and exploration drill targeting in the Baldwin Zone are informed by the results of new 3-D inversion models of aeromagnetic and gravity data that are constrained by available geological data (see News Release dated August 31, 2021). Mistango is confident that the application of constrained modeling of geophysical data is the best approach to exploration drill targeting at the scale of the project area and will allow the Company's exploration program to advance most efficiently towards discovery at the Kirkland West Gold project.

Further Technical Detail
Additional information on the Kirkland West Gold Project can be found here. Phase 1 exploration drilling was focused on the Baldwin Zone where 7,014 metres, representing 18 drill holes, had been completed prior drilling being paused on April 30, 2021 due to difficult ground conditions in the locally rugged terrain arising from an early and rapid spring thaw (News Release dated May 4, 2021).

Mistango's drilling programs in the Baldwin Zone are aimed at discovering mineralization hosted by structural domains that would be similar to, or extensions of mineralized structures within the Kirkland Lake gold mining camp. The Company believes these might include extensions of known structures at the Macassa mine.

About the Kirkland West Project
The Kirkland West Project is adjacent to Kirkland Lake Gold's (KL:TSX) Macassa Mine and includes two main zones, the Baldwin Zone and the Eby Zone that are distinguished by different geological settings. The Baldwin Zone includes land holdings in the western Teck, Grenfell and Eby townships and share a similar geological setting with the Kirkland Lake mining camp. The Eby Zone is 3 km to the southwest within Eby township and features a geological environment that is somewhat distinct from the Baldwin Zone and that is considered to be highly prospective.
