O3 Mining Intersects 1.5 g/t Au over 44.3 Metres at Kierens-Norlartic Infill Program, Marban Engineering
O3 Mining Inc. has provided an update on its Marban Engineering Project in Val-d'Or, Quebec, announcing assay results from 14 drill holes completed in December 2022. The infill drilling program aimed to convert part of the 50,000 ounces of gold in the Pre-feasibility Study resource pit from inferred to indicated. Notable results include 2.1 g/t Au over 84.5 meters in hole O3MA-22-335. The company expressed confidence in expanding resources and updating the mining feasibility study expected in Q1 2024. The infill program consisted of 64 holes totaling 12,153 meters with ongoing assays and multiple rigs actively drilling.
- Drill results indicate potential for resource expansion at Marban, particularly in the Kierens-Norlartic areas.
- High-grade intercepts include 2.1 g/t Au over 84.5 meters and 1.6 g/t Au over 27.0 meters, reflecting strong grades.
- The feasibility study update is expected in Q1 2024, bolstering investor confidence.
- None.
TORONTO, Feb. 23, 2023 /PRNewswire/ - O3 Mining Inc. (TSXV: OIII) (OTCQX: OIIIF) ("O3 Mining" or the "Corporation") is pleased to provide an update on its continuing drilling program on its Marban Engineering Project in Val-d'Or, Quebec, Canada. The Corporation is reporting assay results from 14 holes from the Kierens-Norlartic infill drilling program completed in December 2022 (Press Release – December 22, 2022) seeking technical justification to convert a portion of the remaining 50,000 ounces of gold located within the Pre-feasibility study ("PFS") resource pit shells from the inferred to the indicated category (The Marban PFS, titled "Pre-feasibility Study of the Marban Engineering Project" in accordance with National Instrument 43-101 –Standards of Disclosure for Mineral Projects ("NI 43-101") and dated October 7, 2022 (with an effective date of September 6, 2022) is available on SEDAR (www.sedar.com) under O3 Mining's issuer profile). The 2022 infill program totaled 64 drill holes completed in and around the Norlartic, North, North-North and Kierens pits, of which five holes have assays pending.
"Not only do the results offer us the potential to expand the Kierens-Norlartic resources, but we are also seeing consistency with the estimated grades, giving us confidence that we can convert more material not considered in the PFS to ore, which will be reflected in the Feasibility Study in Q1 2024. We expect to receive more assay results from our drilling campaign in the next weeks and it promises to continue unveiling Marban's resource potential while we continue drilling with three rigs at our Marban project," said O3 Mining President and Chief Executive Officer, Mr. Jose Vizquerra.
- 1.5 g/t Au over 44.3 metres in hole O3MA-22-356 starting at 257.4 meters in the hole in the Norlartic PFS pit shell.
- 1.6 g/t Au over 27.0 metres in hole O3MA-22-385 starting at 356.4 meters in the hole at the bottom of the Norlartic PFS pit shell.
- 2.1 g/t Au over 84.5 metres (true width of approx. 19 metres) in hole O3MA-22-335 starting at 17.6 meters in the hole near surface and at the eastern limit of the Norlartic PFS pit shell.
Most of the results published today are consistent with the estimated grades of the inferred blocks they were aiming to convert. Some of the intercepts are located immediately outside of the PFS pit outline thus offering the possibility to increase the tonnage of the resource if a future pit expansion can be demonstrated. In the case of the Norlartic deposit, it is interesting noting that drill hole O3MA-22-335 returned a notable intercept right next to the property boundary in the south-east corner of the pit shell, where it remains open. The process of updating the ore wireframes is ongoing and will be completed as soon as the full assay results are received. We will then be working with our consultants to update the resource estimate that we expect will form part of the Feasibility Study.

The 2022 infill program comprises 64 drill holes totaling 12,153 metres. The parameters are listed in Table 2 for the entire program. Many significant intercepts have been published in the last months (Press Release – July 6, 2022, and December 22, 2022). Those drill holes also contain a significant amount of intercepts with grade-thickness values between 5 and 20 m*g/t Au.
