Toronto, Ontario – July 26, 2022 – Mistango River Resources Inc. ("Mistango" or the "Company") (MIS:CSE) is pleased to report multiple gold intercepts at its Omega Gold Project, including one that yielded 13.83g/t Au over 1 meter in hole OMG22-006. Mistango will follow up on these gold intercepts at the Omega Gold Project in a subsequent drill program. The Company is also expected to resume drilling at its flagship Kirkland Lake West project located adjacent to Agnico Eagle Mines Limited's Macassa Mine in Kirkland Lake, Ontario.

Details on Gold Intercepts of Omega's 2022 Drill Program:

The winter program at Omega yielded results of 13.83g/t Au in hole OMG22-003 at 33 to 34 meters and several 1 to 2-g/t intercepts in holes OMG002-001, OMG22-002, OMG22-003 and OMG22-004.

The following are details of the key Diamond Drill Hole intercepts:

• OMG22-006: 13.83g/t Au from 33 to 34 meters and 2.56g/t Au from 165 to 169 meters, including 3.82g/t Au from 165 to 167 meters
• OMG22-001: 2.81g/t Au from 162 to 163 meters
• OMG22-003: 0.58g/t Au from 380 to 388 meters and 1g/t Au from 467 to 469 meters, including 1.82g/t Au from 468 to 469 meters and 0.72g/t Au from 574.64 to 578.5 meters, including 1.23t/t Au from 575.64 to 576.64 meters
• OMG22-004: 1.24g/t Au from 52 to 52.67 meters and 1g/t Au from 55.2 to 57 meters
• OMG22-005: 1g/t Au from 130 to 133.6 meters including 1.79g/t Au from 132 to 133 meters and 0.83g/t Au from 144 to 147 meters, including 1.68g/t Au from 146 to 147 meters and 1g/t Au from 245 to 246 meters

Mistango is planning to follow up this program at Omega to expand the known high-grade zones and test for additional gold zones. Mistango will seek to drill five 500-meter holes in the Southwest Extension. This area was not part of the winter program due to permitting challenges, which have since been resolved. This round of drilling will test beneath previous high-grade intercepts on Omega.

About Omega Gold Project

The Omega Project is located in McVittie Township, Ontario, adjacent to the town of Larder Lake. The Project includes a segment of the regional-scale Larder Cadillac Faut Zone that is an important controlling structure for gold mineralization at Orefinders Resources' McGarry Project, located about 8 kilometers to the east of Omega and at the former Kerr-Addison Mine (about 12 Moz Au total production) that is located 12 kilometers to the east of Omega.

The Omega Project consists of two adjacent and contiguous blocks of properties; one block that includes the Omega Mine Resource and another block to the southwest of the mine properties that is referred to as the Southwest Zone. The Omega Mine historically produced gold during two periods, first in the 1920's and again from 1935 to 1947. The Project benefits from access via all-season roads, access to an electrical power grid, and its location within a large and active gold mining district.

Follow Up on 86.2g/t Gold Intersection on its Kirkland West Project:

Preparation for a new drill program on Mistango's Kirkland Lake West Project is set to begin. This program will follow up on January's 86.2g/t Au intercept in hole BAL21-024 at 922.81 to 923.31 meters. The plan is to wedge off of hole BAL22-025 and to test the mineralization 100 meters below and 100 metres east and west of the most recent high grade intercept.  Mistango will also drill unfinished drill holes from the Winter drill program into the same geophysical anomaly. Lastly, the team will drill beneath BAL21-021 as the grade appears to increase with depth. The Company hopes that this drill program will test the continuity of mineralization from the adjacent Macassa mine to Mistango's Kirkland Lake West mine.

About the Kirkland Lake West Project

The Kirkland West Project is adjacent to Agnico Eagle Mines Limited (AEM: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 shares 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.
