O3 Mining Outlines 2021 Objectives

January 21, 2021

Toronto, January 21, 2021 – O3 Mining Inc. (TSX.V: OIII; OTCQX: OIIIF) (“O3 Mining” or the “Corporation”) is pleased to announce its 2021 exploration and development plans focused on unlocking value in the historic Val-d’Or gold region of Québec. It includes a 150,000 metre drilling campaign using up to 12 rigs on the Marban project and Alpha property, and to initiate a Pre-Feasibility Study (“PFS”) on Marban.

2020 was a landmark year for O3 Mining and 2021 is on track to surpass its success, with important catalysts on the horizon,” 

“Having successfully negotiated the partnership of our Garrison project in the Timmins district of Ontario (See press release January 14, 2021), the company has strategically prioritized its attention on its properties in the Abitibi District of Quebec as we continue the largest drill program in company history. Our strategy is two-fold, we aim to build on the momentum of the Marban PEA by defining more resources as we move the project towards a PFS, while on Alpha, continue with the bulk of the drilling as we target resource definition drilling across our land package. Stay tuned for the regular release of drilling results in what promises to be a very busy year for the company.” commented José Vizquerra, President and CEO of O3 Mining.

2021 Outlook

In June 2020, O3 Mining initiated a well-funded 150,000 metre drilling campaign on its projects in Val-d’Or Québec, which will continue through 2021.


Marban is our flagship project and we aim to build on last year’s PEA by initiating the PFS in 2021. We believe there is a lot more gold that we can bring into the existing resources by expanding the existing deposits and drilling other nearby prospective areas with the potential to grow the mining operation we are planning. We are dedicated to advancing Marban as fast as we are able and realizing our vision of becoming a gold producer,” said Mr. Vizquerra.

  • 50,000 metres of drilling.
  • Test extensions of the ore deposits included in the September 2020 PEA (See press release September 8, 2020) to grow the mineral resource base specifically focused on the Norlartic–Kierens, North-North, North Shear, Marban, and the Gold Hawk deposits.
  • Other drilling targets, Orion #8, MK, Malartic H, Marban NE, and Camflo deep, include extensions of historical mineralized zones within 3 kilometres of the PEA pit shells, which offer additional potential to increase resources within the Marban mining project area.
  • Initiate Marban PFS in 2021, with a focus on fieldwork, metallurgical test work, and economic trade-off studies, in addition to advancing environmental impact studies. The company will also continue to explore the geological potential of the Marban project.



At Alpha, we have a three-pronged strategy on a pipeline of targets from grassroots to deposit delineation and expansion, which we are drilling simultaneously. Alpha is often overshadowed by Marban but it is just as exciting due to the significant land position we have in the heart of the Abitibi district. With a purchase option agreed on the Aurbel mill last year, O3 Mining has the opportunity for a relatively low-cost mining operation, once we have defined and delineated sufficient resources and completed economic studies. For this reason, the bulk of the drilling this year is focused on Alpha to rapidly provide up resources so that we can begin to conceptualise possible mining scenarios. As the recent partnership of our Garrison project shows, the appetite for gold deposits in the principle gold-producing regions is growing, which bodes well for the future advancement of Alpha and is why we are also pursuing discoveries,” said Jose Vizquerra.

  • 100,000 meters of drilling.
  • Expand known deposits to depth at Orenada, Simkar, Akasaba, and Bulldog and proceed to a resource estimate when we feel there is enough resource to generate an economic scenario.
  • Follow-up on significant drill intercepts to prove up the continuity of grades and widths with the aim of turning into new deposits at Epsilon, Pontiac East, Omega, Valdora, and El Sol.
  • Test targets across the property to make new discoveries on the four mineralization types: Cadillac Fault, Skarn/porphyry, Anamaque Sill, and Sigma–Lamaque corridor. These targets were generated last year from a combination of in-house compilation, summer trenching program, and use of Artificial intelligence (“AI”) targeting study by Mira Geoscience.

2020 Milestones

2020 was a year of achievement at O3 Mining as we achieved many significant milestones. These include the delivery of a PEA on Marban with an after-tax net present value (PNV) of C$423M and a 25.2% internal rate of return (IRR) at a US$1,450/oz gold reference price, the delivery of a PEA on Garrison with an after-tax NPV of C$321M and 33% IRR, the purchase option on the Aurbel mill for Alpha, and the completion of 68,263 meters drilled, surpassing the 50,000 meters we originally planned for the year (See press release January 20, 2020). In addition, O3 Mining raised C$40.2 million via a bought deal (See press release June 19, 2020) and is now listed on the OTCQX Market to help strengthen our US shareholder base.


Qualified Person

The scientific and technical content of this news release has been reviewed, prepared, and approved by Mr. Louis Gariepy. (OIQ #107538), VP Exploration, who is a “qualified person” as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

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.
