Two drill rigs have been mobilized to begin an 8,000-metre drill program in the Cameron and Florence sectors of the Kinebik Project

TSXV:OIII | OTCQX:OIIIF - O3 Mining

TORONTO, Nov. 20, 2024 - O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) ("O3 Mining" or the "Corporation") is pleased to announce the start of an 8,000-metre drill campaign at the Cameron and Florence sectors of the Kinebik Project, which straddles over 55 km of strike along the prolific auriferous Casa Berardi trend. The Corporation mobilized two drill rigs to initiate the drill campaign.

O3 Mining's President and Chief Executive Officer, Mr. José Vizquerra commented: "This exploration program represents the first drilling campaign that O3 Mining will begin on the Kinebik Project. Our team has worked hard over the past year to consolidate the Kinebik Project into a district scale property with excellent exploration potential. After completing compilation of data, field work, and identification of exploration targets, we have now mobilized two drill rigs and begun our first campaign on Kinebik. This project will play an important role in our exploration strategy as development continues at Marban Alliance."

The Kinebik Project straddles over 55 km of strike along the prolific auriferous Casa Berardi trend, which extends over 400 km in the northern part of the Abitibi Greenstone Belt. Along its length, there are five mining districts including the +5.0M oz Au world-class Casa Berardi deposit, the Douay deposit (3.0M oz Au at 1.1 g/t Au), and the Vezza deposit (0.3M oz Au at 5.6 g/t Au). The Kinebik Project is easily accessible all year round through the main roads to Matagami and Chibougamau cities. As a result of an ongoing consolidation process, the current project now covers a total of 47,510 hectares.

The Kinebik sector, acquired from NewOrigin Gold Corp. in May 2023, comprises 14,636 hectares and covers over 30 km of strike along the Casa Berardi trend and its host iron formations, 150 km east of the Casa Berardi mine. The Cameron sector, acquired in December 2023 from Globex Mining Enterprises Inc. totals 8,220 hectares and covers several prospective structures. One of them, the Cameron Lake deformation zone, is a structural zone up to 2.0 km wide and forms part of the wider Casa Berardi break corridor.

The Cameron Main mineral occurrence returned historical intercepts of 2.2 g/t Au over 13.8 m and 5.3 g/t Au over 5.5 m associated with quartz veins in sheared graywackes and cherts. The upcoming drilling program is being conducted to validate those intercepts, test their lateral extensions and drill targets along the 10 km segment of the Cameron deformation zone on the property. These targets were designed based on the 2024 summer mapping program, magnetic features and soil geochemical anomalies from the summer 2024 survey.

The Desjardins property acquired from SOQUEM Inc. in September 2024 covers a total area of 2,186 hectares. Several drill intercepts associated with iron formations were obtained on that property, namely 6.6 g/t Au over 4.7 m and 13.7 g/t Au over 5.0 m, and remain open laterally and at depth, offering immediate drilling targets.

Finally, the 16,094 hectares Lac Esther property was acquired from Midland Exploration Inc. in October 2024. It covers the eastern extension of the rocks sequences and structural break found in the Florence sector.

The Corporation believes that the Kinebik Project offers promising discovery potential based on its strategic geological location, confirmed gold occurrences, and limited historical drilling.
