Moneta to Acquire Garrison Project from O3 Mining to Create a Leading Canadian Gold Development Company with 4.0m Oz Gold Indicated and 4.4m Oz Gold Inferred

Toronto, Ontario--(Newsfile Corp. - January 14, 2021) -  Moneta Porcupine Mines Inc. (TSX: ME) (OTC PINK: MPUCF) (FSE: MOP) ("Moneta" or the "Company") is pleased to announce that the Company has entered into a definitive share purchase agreement (the "Purchase Agreement") with O3 Mining Inc. (TSX.V:OIII; OTCQX:OQMGF) ("O3 Mining") pursuant to which Moneta will acquire all of the issued and outstanding shares of Northern Gold Mining Inc., a wholly-owned subsidiary of O3 Mining, which owns 100% of the Golden Bear assets, including the Garrison Gold project ("Garrison") located adjacent to and contiguous with Moneta's Golden Highway project in the Timmins Gold Camp (the "Transaction").

Under the terms of the Purchase Agreement, O3 Mining shall receive approximately 150 million common shares of Moneta ("Moneta Shares"). Upon completion of the Transaction, and prior to the financing described below, O3 Mining is expected to own approximately 30% of the outstanding Moneta shares.

Concurrent with the Transaction, Moneta will raise approximately $20 million in equity.

Transaction Highlights:

• Creation of a leading gold exploration and development company with 3,967,000 ounces (oz) gold (Au) in the indicated category and 4,399,000 oz Au in the inferred category located in the prolific Timmins Gold Camp
  • 3,335,000 oz Au open pit indicated gold resources and 2,270,000 oz Au open pit inferred gold resources
  • 632,000 oz Au underground indicated gold resources and 2,129,000 oz Au underground inferred gold resources
• Addition of 1,822,000 oz Au in the indicated category and 1,062,000 oz Au in the inferred category to Moneta's mineral inventory immediately adjacent to the Golden Highway project
• Substantial development and operating synergies through an integrated project
  • Potential for a much larger scale project than originally envisioned for the Preliminary Economic Assessment ("PEA") on the South West deposit announced in September 2020
  • Potential starter pit at Garrison with outcropping gold resources at higher grades and a lower strip ratio to augment the development of Moneta's open pit resources
• Addition of 9,269 hectares (ha) (92.69 square kilometres (sq.km)) of adjacent and contiguous prospective ground to Moneta's claim base in the Timmins Gold Camp
• Concurrent $20 million equity financing to fund an aggressive drill campaign
• Enhanced capital markets profile and exposure
• Platform for further district consolidation

Gary O'Connor, CEO of Moneta, commented; "The acquisition of the Golden Bear assets will transform Moneta into one of the largest gold development companies in North America with a significant resource and land holding in Canada's most prolific gold mining camp. The Golden Bear assets, including the Garrison Gold deposits, are adjacent to our flagship Golden Highway project and provide significant synergies and multiple options for the development of our gold resources. Moneta will hold 3,967,000 ounces of indicated gold resources and 4,339,000 million ounces of inferred gold resources including both high-grade bulk tonnage underground deposits and near surface open pit resources. With completion of the proposed equity financing, the Company will be well funded to test the expansion potential of the integrated project. The Transaction provides a good endorsement of our project and adds a highly successful project development company as a partner".

José Vizquerra, President and CEO of O3 Mining, commented: "O3 Mining is pleased to unlock value for our shareholders through our investment in, and support of, Moneta, and the possible future development of a large and long-life gold project in Timmins, Ontario - one of Canada's most productive gold camps. The consolidation of these two historically fractioned mining camps will allow for a more systematic exploration strategy going forward, and unlock value for our shareholders and other Moneta shareholders alike as the project develops. We look forward to partnering with Moneta's management team, through our board representation, and being part of Moneta's growth story in the Timmins Mining Camp, in our role as a significant shareholder".

Benefits to Shareholders

The Transaction is expected to result in the following benefits for our shareholders:

• One of the largest undeveloped gold mining projects in North America
• Potential for a much larger scale project than originally envisioned in the PEA studies recently completed on the Golden Highway and Garrison gold projects (The "Tower Gold Project") with substantial economic benefits to be realized from operational and development synergies
• Land position increased by 73% for resource expansion in the prolific Timmins Gold Camp
• Potential starter pit at Garrison containing 1,070,000 oz Au at a grade of 1.04 g/t Au at a low strip ratio (2.7:1) and a cash production cost of US$721/oz of Au with outcropping gold mineralization to augment the development of Moneta's open pit resources
• Significant increase of gold resources in the indicated category
• Combined exploration agreements and consolidation of good working relations with the Wahgoshig First Nation
• Continued resource expansion potential and opportunities

About the Golden Bear Assets

O3 Mining holds 9,269 ha of prospective land within the Golden Bear project located adjacent to or in near proximity to Moneta's Golden Highway project, 100 km east of Timmins. O3 Mining completed an updated resource estimate and preliminary economic assessment (PEA) study on the Garrison Gold project within the Golden Bear project in December 2020. The study highlighted a measured and indicated open pit resource of 1,822,000 ounces contained within 66.3 Mt @ 0.86 g/t Au and an inferred open pit resource of 1,062,000 ounces contained within 45.3 Mt @ 0.73 g/t Au at a 0.30 g/t Au cut-off. The PEA study showed an open pit mining operation consisting of a 12-year mine life with an after-tax NPV5% of C$321MM, IRR of 33% and a 2.3 year payback. The project envisaged open pit mining producing 121,000 oz/pa in years 1 to 8 (94,000 oz/pa LOM), at a strip ratio of 2.7:1 at a cash cost of US$721/oz using a gold price of US$1,450/oz and an exchange rate of C US$0.75/C$.
