Jason Kosec, President, CEO & Director of Hemlo Mining, commented: “Q1 was transformational for the Company, representing our first full quarter of ownership of the Hemlo Gold Mine and laying a strong foundation for the year ahead. We delivered production in line with expectations while upholding our standards for health, safety, and environmental performance. During the quarter, we advanced our strategy of optimization, reinvestment, and growth across multiple fronts—transitioning to an owner-operated model ahead of schedule; launching our 130,000-metre drill program; advancing an updated mineral resource estimate; initiating key mining trade-off studies to support a future technical study; making strong progress transitioning off legacy Barrick systems; hiring key personnel across corporate and site functions; and executing a strategic royalty buyback. We also strengthened our financial position through the full repayment of our revolving credit facility. The pace and breadth of progress in the first quarter reinforce our confidence in the opportunity ahead at Hemlo.”

First Quarter 2026 Operating Highlights

1. Gold produced represents gold poured during the period.
2. Operating statistics are presented on a 100% basis. The Interlake claims are subject to a 50% net profits interest (“NPI”) royalty with Franco-Nevada Corporation.
3. Attributable gold is calculated as 100% of gold from Williams and 50% of gold from Interlake.

The Hemlo Gold Mine (“Hemlo” or the “Mine”) continued its strong safety performance in Q1, with no environmental non-compliances and no Lost Time Injury (“LTI”) events recorded. This marked 33 consecutive months of no LTIs. During the quarter, Hemlo was awarded the prestigious John T. Ryan Trophy for continued improvements in safety. The John T. Ryan Safety Trophies are presented annually by the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) to recognize mining operations in Canada that achieve the lowest reportable injury frequencies in their respective categories during the previous calendar year.

The Hemlo Gold Mine successfully transitioned from an underground mining contractor workforce to owner-operated on March 16, 2026, two weeks ahead of schedule with 97% of the contractor workforce accepting positions as part of the transition. An additional 42 positions were filled during the period to support operational optimization efforts and future production increases. While the primary underground mining tasks have been transitioned to owner-operated mining, long-term partnerships with certain contractors will be maintained, specifically for a portion of underground development, Alimak mining and production drilling. The upgrade to the mining fleet continued to progress during the quarter with two of the 21 planned pieces of new equipment being commissioned in Q1.

Various maintenance activities were undertaken during the quarter, with the most significant tasks being the refurbishment of an underground crusher and the replacement of the hoist cable, which was completed ahead of schedule. The Company also completed an evaluation of all existing equipment to  support refurbishment, replacement, and fleet expansion for future production increases.

In addition, intensive training programs have been implemented to upskill the workforce and build a pipeline of future employees, with focus being placed on people residing in the communities nearby, including Marathon, Manitouwadge, White River and the Biigtigong Nishnaabeg and Netmizaaggamig Nishnaabeg First Nations.

The Company expects to provide 2026 operating and cost guidance in the second half of 2026.
