Toronto, February 4, 2021 – O3 Mining Inc. (TSX.V: OIII; OTCQX: OIIIF) (“O3 Mining” or the “Corporation”) is pleased to provide new drilling results from the Marban Alliance project on its Malartic Property in Val-d’Or, Québec, as part of its well-funded 150,000 metre drilling program.
Current drilling on the Marban Alliance project focuses on expanding mineralization outside of the proposed pit areas outlined in the Preliminary Economic Assessment (“PEA”) released on September 08, 2020. The 2020-2021 drilling program consists of 50,000 metres to test extensions of the deposits and zones outside of the PEA pit areas. New drilling results from seven drill holes include:
A 3D-model of the Malartic property and the Marban Alliance project is available on the Company’s website at https://o3mining.com/presentations/drill-results.
Late last year, we published a positive PEA on Marban Alliance and committed to making it even better through continued exploration. By investing the time and money into our drill program we continue to grow the various Marban Alliance deposits and the results will be included with the next resource update, which will underline how the development of Marban Alliance is becoming an even more attractive possibility. Drilling has successfully intercepted mineralization in new areas including what we think is a new parallel structure to Marban Alliance called Golden Bridge, which after more work, could be brought into the project economics and further add to the benefits of a future production scenario,”President and CEO José Vizquerra.
The new Golden Bridge zone discovery is defined by three drill holes covering an area of 175 metres by 100 metres at 175 metres vertical depth and remains open to the west, at depth, and up to the surface. O3 Mining believes that the near surface Golden Bridge zone offers the potential to generate a new open pit resource, just 200 metres from the PEA Norlartic pit. Initial interpretation suggests that the Golden Bridge zones are associated with an east-west trending splay of the Marbenite and Norbenite shears. If proven, this would offer a lateral exploration potential of an additional 650 metres along the Golden Bridge structure. The two intercepts associated with albitized dykes in O3MA-20-013 are 65 meters apart in the hole and are located at a vertical depth of 450 metres on average. The zones remain open laterally and at depth.
The intercept in hole O3MA-20-028 expands the near-surface mineralization 30 metres east of previously reported intercepts in holes O3MA-20-005 and O3MA-20-006 (see press release November 03, 2020).The intercept in hole O3MA-20-013 within the Kierens PEA pit shell shows the high-grade nature of mineralization, which will be beneficial to the project economics. The intercept at Gold Hawk supports the continuity of the zone over 75 metres down dip from the previously reported high-grade intercept in hole O3MA-20-008 (see press release November 24, 2020).
The primary objective of these holes was to cross the Kierens-Norlatic corridor at shallow depth while drilling extensions at depth of the Gold Hawk zone. These new results suggest that the Kierens and Norlartic ore bodies come closer to the surface than previously interpreted and, could potentially connect when properly delineated. Additionally, the discovery of the Golden Bridge zone shows the potential to expand resources associated with splay structures connecting the Norbenite and Marbenite shears. A total of 38 drill holes totalling 20,591 meters have been drilled since the beginning of the campaign in August 2020 at the Marban Alliance Project, focusing on the Kierens, Kierens NW, Gold Hawk, Orion, MK, North Shear, North North, and Marban Alliance NE zones. Assay results from 27 drill holes are pending. Now that the winter conditions allow accessing humid lands, the focus will shift over to the Marbenite Deep, Marban Alliance East Deep (both adjacent to Marban Alliance pit) as well as at North North and North Shear. Follow-up drilling on the intercepts released today will occur during the summer months as the Company prioritizes areas only accessible during winter.

The Kierens zone has been intersected at shallow depth in four drill holes. Holes O3MA-20-011 and O3MA-20-013 hit the Kierens zone in the middle of the proposed Kierens pit and confirmed the continuity of the mineralization. Hole O3MA-20-028 is located 175 m SE of the Kierens proposed pit limit and returned 1.5 g/t Au over 6.5 m expanding the open-pit potential further east. The three holes intersected quartz-calcite stockwork associated with up to 5% disseminated pyrite in a basaltic unit crosscut by gabbroic dykes. The Kierens zone is within the hanging wall of the Norbenite shear located at the contact with the ultramafic rocks. Hole O3MA-20-018 intersected the Kierens zone at the western extremity of the proposed pit. It intersected a stockwork of quartz-calcite veins related to gabbroic dykes hosted in sheared komatiite that returned 9.4 g/t Au over 1.0 m.
The Marbenite shear is separated from the Norbenite shear by a 150 m thick tabular granodiorite intrusion. During the fall, O3MA-20-001 intersected stockwork quartz calcite veins in a weakly sericitized and pyritized portion of the granodiorite that yielded 4.4 g/t Au over 1.5 m (see press release November 24, 2020). Holes O3MA-20-012 and O3MA-20-015 show that the previously observed stockwork forms a continuous structure within the granodiorite now recognized as the Golden Bridge zone. Both holes intersected a stockwork consisting of 15% quartz-calcite veins associated with disseminated pyrite as well as molybdenite stringers. Hole O3MA-20-012 intersected 1.2 g/t Au over 9.7 m and hole O3MA-20-015 returned values of 2.0 g/t Au and 2.0 g/t Ag over 5.4 m. The new mineralized zone remains open at depth, up-dip, and 650 m to the west. Follow-up holes will be drilled next summer on the up-dip and westward extensions.
Hole O3MA-20-013 crosscut a series of albitized dykes that resulted in strong biotization of the surrounding ultramafic rocks. Gold is found associated with the biotized ultramafic rocks with few quartz-calcite veinlets as well as within the dykes. The first intercept returned 13.5 g/t Au over 1.3 m where mineralization is restricted to the biotite zone, while the second intercept of 2.8 g/t Au over 4.3 m is related to the dyke and its altered walls.
Hole O3MA-20-012 intersected the Gold Hawk zone 75 m below the high-grade intercept of hole O3MA-20-008 that returned a spectacular grade of 383 g/t over 2.0 m (see press release November 24, 2020). The mineralization in hole O3MA-20-012 related to the Gold Hawk zone yielded an intercept of 4.6 g/t Au over 1.2 m consisting of a 15 cm quartz-calcite-chlorite vein within an iron-rich basalt in contact with a mafic dyke in the hanging wall of the Marbenite shear. The vein is related to a high-grade interval of 9.6 g/t Au over 0.5 m. The geological context is the same as in hole O3MA-20-008 and shows the Gold Hawk zone’s depth potential depth potential of the Gold Hawk zone.

Quality Control and Reporting Protocols
True width determination is currently unknown but is estimated at 65-80% of the reported core length interval for the zones. Assays are uncut except where indicated. 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 QA/QC program. Third-party assays are submitted to other designated laboratories for 5% of all samples. Drill program design, Quality Assurance/Quality Control (“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.
