UPPER BEAVER

The Upper Beaver project hosted 2.8 million ounces of gold and 54,930 tonnes of copper in probable mineral reserves (23.2 million tonnes grading 3.71 g/t gold and 0.24% copper), 0.5 million ounces of gold and 12,118 tonnes of copper in indicated mineral resources (7.6 million tonnes grading 2.03 g/t gold and 0.16% copper) and 0.4 million ounces of gold and 10,649 tonnes of copper in inferred mineral resources (3.0 million tonnes grading 4.12 g/t gold and 0.36% copper) at December 31, 2025.

The Company continued to accelerate project development at Upper Beaver through a phased approach to project de-risking that includes developing an exploration shaft to a depth of 760 metres and an exploration ramp to a depth of 160 metres that will be used to establish underground drilling platforms.

Development activities during 2025 continued to advance ahead of schedule. The exploration ramp progressed by 507 metres, reaching a depth of 70 metres at year-end, and shaft sinking began with the first blast completed in November to reach a depth of 155 metres by year‑end 2025.

A high‑intensity drilling program from surface began at Upper Beaver in 2025 and is ongoing. The program is similar in design to the high-intensity drilling program recently completed at Detour Lake that has contributed to improved planning for the potential development of underground mineral resources.

The high-intensity drilling program at Upper Beaver is targeting the lower level of the deposit, which is dominated by intrusion-suite host rocks, with the objective of validating the resource model and grade variability at greater depths in the most representative geological zones of the deposit.

Depending on the results, this high-intensity drilling program could replace a planned bulk sample at the 760‑metre level and has the potential to bring forward initial production to early 2030.

In 2026, the Company expects to spend approximately $56.1 million at Upper Beaver, including approximately $52 million on the exploration ramp, exploration shaft and the first bulk sample, and approximately $4.1 million for 10,500 metres of high-intensity drilling. The bulk sample will be taken from the ramp at a depth of 160 metres from the upper level of the deposit, which is dominated by basaltic host lithologies, and will provide material for testing selective mining assumptions in this area of the deposit.

Exploration results from recent years at Upper Beaver show the potential to increase the mineral resources and to convert inferred mineral resources at depth using underground access via the planned exploration shaft and ramp infrastructure.

Regional exploration will continue to develop and advance the pipeline of targets in the Kirkland Lake area.
