CEO AND SHAREHOLDER COMMENTARY

Jody Kuzenko, President and Chief Executive Officer of Torex, stated:

“The Los Reyes Project represents a unique opportunity for the Torex team to develop a high-quality asset with the potential for a high margin, low capital, and long-life operation in a jurisdiction that we know very well. The acquisition of Prime Mining, and the previously announced all-cash acquisition of Reyna Silver, support our strategy to systematically build a diversified, Americas-focused precious metals producer with a portfolio of producing, development, and exploration stage assets.

“Our extensive due diligence reinforced the scarcity of an asset of this quality, and we look forward to demonstrating the significant value we see in this exciting project. Los Reyes has multiple high-potential mineralized zones which remain open along strike and at depth, and we are confident that the project has strong untapped upside with numerous avenues for growth.

“Over the last 15 years, the Torex team has demonstrated the technical and in-country expertise to successfully advance projects from exploration through to development and production in Mexico, delivering considerable value to our shareholders. We will leverage these competencies, along with our significant expected free cash flow from the now completed Media Luna Project, to unlock and maximize the value of Los Reyes through development and production. We look forward to building strong relationships with the local communities in Cosalá, and we will work with them to ensure that the project delivers meaningful and sustainable benefits, just as we have and continue to do at Morelos.”

Scott Hicks, Chief Executive Officer and Director of Prime Mining, added:

“The addition of Prime Mining’s high-quality Los Reyes Project to the Torex pipeline as its next development asset presents both Prime Mining and Torex shareholders with substantial value enhancement through this share-based acquisition. In addition to gaining exposure to Torex’s free-cash flowing Morelos Complex, Prime Mining shareholders can continue to realize significant value creation as Los Reyes is developed with the benefit of Torex’s operational and development experience in Mexico. Both companies are aligned in their community and employee-focused values, approach to environmental stewardship and commitment to ensuring that all stakeholders will benefit through this combination. Prime looks forward to working with Torex through the transitionary period.

“Our Board, Management, and key shareholders view this opportunity as a great way to de-risk and unlock the full exploration and project potential that we collectively see in Los Reyes through our meaningful pro-forma ownership in Torex. I would like to take this opportunity to thank the Prime Mining team, Board of Directors, and our other stakeholders for all their outstanding contributions in getting Prime Mining to this exciting stage.”

Pierre Lassonde, commented:

“I am truly excited to be a part of this business combination. Jody and her team are, like us, proven creators of shareholder value. The Morelos Complex is a world class asset that, combined with our high-grade Los Reyes gold-silver deposit, will deliver outsized shareholder returns. I would like to thank Scott, Murray, and the team at Prime Mining for advancing the high-grade, gold-silver system at Los Reyes, and I look forward to working with Jody, Rick, and the team at Torex as we aim to do our part in building a new high-margin, intermediate gold producer.”
