Ontario's largest copper resource, the Thierry Copper Project spans 7,907 hectares and historically produced 5.8 million tonnes grading 1.13% copper, and 0.14% nickel. Thierry currently hosts two resource-stage deposits—Thierry Underground, known as K2 and the K1 Open Pit, both with National Instrument 43-101. Thierry has two additional near surface zones—J & G zones—with historical resources. Thierry can be easily accessed via all-season road and is proximal to other necessary infrastructure including hydroelectric power, rail and airport. Both XXIX’s Opemiska and Thierry Mine historically shipped its copper concentrates to the Horne Smelter in Rouyn-Noranda.

La propriété Thierry abrite une ressource conforme à la norme NI 43-101 répartie sur deux zones : le dépôt souterrain Thierry (K2-1) et le dépôt à ciel ouvert K1-1, ainsi que des ressources historiques dans les zones J et G.

L'acquisition de Thierry augmente de 70 % la base actuelle de ressources en cuivre d'XXIX. XXIX rappelle à ses actionnaires l'Opemiska, la ressource de cuivre à ciel ouvert la plus riche du Canada.

The Thierry Property, and specifically the Thierry underground deposit, was the subject of a PEA study by P&E Mining Consultants in 2021 that outlined a 17-year mine life, producing at a rate of 4,000 tpd, recovering 567Mlbs Cu, and 21Mlbs Ni. The PEA showed an after-tax NPV8% of $177.9M, an IRR of 18.9% and a payback period of 3.2 years. It is important to note that the PEA did not include the K1-1 open pit deposit and that XXIX will seek to drill out the open pit resources and evaluate a larger bulk tonnage scenario for the Project.
