TORONTO, June 8, 2023 /CNW/ - O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) ("O3 Mining" or the "Corporation") is pleased to provide additional assay results from our winter drill program on our Marban Engineering Project in Val-d'Or, Québec, Canada. In this news release, the Corporation is reporting 22 significant intercepts in 13 drill holes from the Malartic H deposit drill program completed in March 2023, which expands upon the 17 significant intercepts disclosed in O3 Mining's new release dated May 16, 2023 (entitled "O3 Mining Intersects 5.9 g/t Au Over 10.1 Metres on Malartic H"). The Malartic H deposit consists of multiple stacked lenses now covering an area of 950 metres along strike and 300 metres wide.

Highlights:
4.0 g/t Au over 36.5 metres in hole O3MA-23-485 at a vertical depth of 66 metres, including 231.0 g/t over 0.5 metre and 1.2 g/t over 14.4 metres2.8 g/t Au over 16.9 metres in hole O3MA-22-471 at a vertical depth of 182 metres7.2 g/t Au over 4.5 metres in hole O3MA-22-476 at a vertical depth of 219 metres
O3 Mining's President and Chief Executive Officer, Mr. José Vizquerra commented: "These new robust and shallow intercepts from our 2023 winter drill program bring us confidence ahead of the maiden near surface resource estimate to be released shortly. Additionally, higher grade intercepts deeper in the system could signal potential for an underground operation."
The 2023 winter drill program on Malartic H covered a one kilometre stretch, filling gaps covered by historic drilling in the shallow part of the Malartic H deposit to achieve an 80 metre spacing. Historic drilling was completed by NioGold Mining Corp. and Aur Resources Inc., with QA/QC procedures applied and documented. All assays have been received (except a portion of hole O3MA-23-491 that replicate hole O3MA-23-485, 6 metres apart), and O3 Mining expects to release a maiden mineral resource estimate on the Malartic H deposit later this month.
Malartic H is located within five kilometres of the proposed processing plant described in the current pre-feasibility study on the Corporation's Marban Engineering Project.

About the Malartic H deposit
The Malartic H deposit has a recognized strike length of 950 metres, 300 metres wide and down to a vertical depth of 500 metres. The mineralized system is partially open laterally and completely open at depth. It is located about 1 kilometre to the north of the Malartic Hygrade former mine, near the hinge of a regional Z-shaped fold. More importantly the Malartic H deposit is also located between the northwestern extensions of the Marbenite and Norbenite shears, which host most of the resources of the Marban Engineering Project. At Malartic H, the two shears are northwest-trending and dipping around 70 degrees to the northeast. The deposit is hosted by an alternance of mafic and ultramafic volcanic sequence of the Jacola formation. Similar to the Hygrade area, numerous intermediate to felsic dyke systems are injected in the volcanic sequence. The mineralization occurs as disseminated pyrite with local visible gold in quartz veins and veinlets and disseminated in the host rock. Zones are spatially correlated shears within mafic volcanic units or with the intermediate to felsic dykes. All zones are roughly subparallel.
The 2023 winter drilling program on the Malartic H deposit comprises 23 drill holes totaling 6,948 metres. The parameters are listed in Table 3 for the entire program. Assay results are completely received except for the one twin hole mentioned above (which results are pending).

Qualified Persons
The scientific and technical content of this news release has been prepared, reviewed and approved by Mr. Sébastien Vigneau (OGQ #993), Principal Geologist of O3 Mining, who is a "qualified person" within the meaning of National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101").
Quality Assurance/Quality Control
Intercepts occur within geological confines of major zones but have not been correlated to individual vein domains at this time. Half-core samples are shipped to Agat laboratory in Val-d'Or, Québec, and Mississauga, Ontario for assaying. The core is crushed to 75% passing -2 mm (10 mesh), a 250 g split of this material is pulverized to 85% passing 75 microns (200 mesh) and 50 g is analyzed by Fire Assay (FA) with an Atomic Absorption Spectrometry (AAS) finish. Samples assaying >10.0 g/t Au are re-analyzed with a gravimetric finish using a 50 g charge.
Commercial certified standard material and blanks are systematically inserted by O3 Mining's geologists into the sample chain after every 18 core samples as part of the quality assurance and quality control ("QA/QC") program. Third-party assays are submitted to other designated laboratories for 5% of mineralized samples. Drill program design, QA/QC, and interpretation of results are performed by qualified persons employing a QA/QC program consistent with NI 43-101 and industry best practices.
