Mistango Launches 3-D Geophysical Modeling for Drill Targeting at its Kirkland West Gold Project

TORONTO, Aug. 31, 2021 - Mistango River Resources Inc. ("Mistango" or the "Company") (CSE: MIS) is pleased to announce that Mira Geoscience has been commissioned to complete integrated 3-D geophysical and geological modeling on the Kirkland West Gold Project in the southern Abitibi Greenstone Belt, Ontario. The modeling program is designed to generate high priority drill targets for the upcoming drilling campaign in October 2021.

Constrained 3-D geophysical modeling of publicly available aeromagnetic and gravity data will be performed for the Baldwin Zone in the northern part of the Kirkland West Project. The resulting models will serve as a basis to construct 3-D surfaces for the main geological contacts and fault structures. The objective will be to define discrete exploration drill targets that would be associated with geological and structural environments similar to those that host world-class gold deposits such as the Macassa mine, within the Kirkland Lake mining camp that is located a few kilometres to the east.

Drilling is expected to kick off in October, 2021 and will represent a total of approximately 5,000 metres. The upcoming drilling campaign will represent an expansion of the 10,000 metre Phase 1 drilling program that was temporarily halted in April, 2021, after approximately 7,000 metres (18 holes) had been completed due to difficult conditions during the spring thaw season (News Release dated July 26, 2021). The constrained 3-D geophysical models and structural interpretations will lead to increased confidence in the definition of high priority targets at the Baldwin Zone.

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 differentiated and highly prospective geological setting.
