With close to 100 years of history, Hudbay is proud to be the third-largest copper producer in Canada with operations in British Columbia and Manitoba.

Our Canadian business can trace its history back almost a century, to our first mines in Manitoba’s Flin Flon Snow Lake Greenstone Belt. It was there we laid the foundation for the mine-building expertise and community engagement that distinguish Hudbay to this day. Our operational focus in Canada, with two operating mines in British Columbia and Manitoba, is core to our ability to create sustainable long-term value for shareholders.

With the addition of the Copper Mountain Mine, Hudbay has become the third-largest copper producer in Canada. The Copper Mountain Mine, located south of Princeton, British Columbia, is a conventional open pit, truck and shovel operation. Hudbay owns 75% of the Copper Mountain Mine, with the remainder owned by Mitsubishi Materials Corporation. The mine has a 45,000 tonnes per day plant that utilizes a conventional crushing, grinding and flotation circuit to produce copper concentrates with gold and silver credits. Hudbay will be releasing an updated technical report for Copper Mountain later in 2023 to provide reserve and resource estimates and an updated life of mine plan.

Manitoba’s Snow Lake region continues to be an area of opportunity as our reserves, processing capacity and exploration activities expand in the region, setting the stage for a new phase of growth. Our Lalor mine (gold, zinc, copper, silver) in Snow Lake is a meaningful low-cost gold producer that substantially benefited from the refurbishment of the New Britannia mill in 2021. Hudbay has been actively conducting drilling activities testing the down-plunge gold and copper extensions of the Lalor deposit, in the first step out drilling in the deeper zones at Lalor since the initial discovery of the gold zones in 2009.

Environment

We take environmental performance seriously, and are implementing the Mining Association of Canada’s TSM (Towards Sustainable Mining) protocols for Biodiversity, Energy and Greenhouse Gas and Tailings at all of our operations. These protocols provide clear guidelines for monitoring, measuring and reporting on performance. They emphasize management processes, senior executive oversight and expert third-party reviews, which help to ensure appropriate technical standards of construction, maintenance and operation.

AAA Rating
Attained for tailings management in the latest TSM Progress Report

Community

Hudbay didn’t just build a successful business in northern Manitoba – it helped build successful communities like the city of Flin Flon. We recognize and acknowledge the land on which we will operate in Manitoba is on the traditional territory of the Swampy Cree and Woodland Cree, the Anishinaabe, OjiCree, Dene and homeland of the Métis Nation peoples.

We acknowledge that we operate in British Columbia on the unceded territories of the Upper and Lower Similkameen Indian Bands. Copper Mountain has participation agreements in place with the Upper Similkameen Indian Band and the Lower Similkameen Indian Band as well as support from the town of Princeton and the province of British Columbia.

Through jobs, business opportunities, taxes and royalties, community development programs and infrastructure investments, we support and advance long-term socio-economic development. Developing job skills within indigenous communities not only helps the communities; it also benefits Hudbay by growing the base from which we hire and increasing the number of qualified suppliers from which we procure goods and services.

People

We recognize that employing people with different backgrounds, experiences and perspectives makes us stronger and fosters collaboration. In Manitoba, we partnered with the Northern Manitoba Sector Council to increase recruitment of indigenous employees. Twelve people have been hired under the program so far. Separately, two women in our Manitoba Business Unit founded the Hudbay Women’s Network, an employee-led voluntary resource group. The group’s founding principle is gender inclusion and its goal is to empower Hudbay employees by providing a vehicle for professional growth and a strong voice.

Hudbay will be releasing an updated technical report in the second half of 2023.

The current technical report for the Copper Mountain mine was filed by Copper Mountain Mining Corp. ("Copper Mountain") on September 30, 2022 and a copy is available on Copper Mountain's SEDAR profile.

Note: totals may not add up correctly due to rounding.
1 Mineral resources are exclusive of mineral reserves and do not have demonstrated economic viability.
2 Mineral resources do not include factors for mining recovery or dilution.
3 Base metal mineral resources are estimated based on the assumption that they would be processed at the Stall concentrator while gold mineral resources are estimated based on the assumption that they would be processed at the New Britannia concentrator.
4 Long-term metal prices of $1.20 per pound zinc, $1,650 per ounce gold, $3.60 per pound copper, and $22.00 per ounce silver with an exchange rate of 1.33 C$/US$ were used to estimate mineral reserves and resources.
5 Lalor mineral reserves and resources are estimated using NSR cut-off ranging from C$137 to C$168 per tonne assuming a long hole mining method and depending on the mill destination.
6 Individual stope gold grades at Lalor were capped at 10 grams per tonne as a prudent estimate until reserves-to-mill reconciliations can be developed to support the recovery of higher-grade gold. This capping method resulted in an approximate 3% reduction in the overall gold reserve grade at Lalor.
7 1901 mineral reserves and resources are estimated using a minimum NSR cut-off of C$166 per tonne assuming the material is mined via post pillar cut-and-fill methods and is processed at the Stall mill.

4 Long-term metal prices of $1.15 per pound zinc, $1,500 per ounce gold, $3.45 per pound copper, and $20.00 per ounce silver with an exchange rate of 1.30 C$/US$ were used to confirm the economic viability of the mineral reserve estimates.
5 WIM mineral reserves are estimated using a minimum NSR cut-off of C$150 per tonne, assuming processing recoveries of 98% for copper, 88% for gold and 70% for silver based on processing through New Britannia mill's flotation and tails leach circuits.
6 3 Zone mineral reserves are estimated using a minimum NSR cut-off of C$150 per tonne, assuming processing recoveries of 85% for gold based on processing through New Britannia mill's leach circuit.
7 New Britannia mineral resource estimates have been reported at a minimum true width of 1.5 metres and with a cut-off grade varying from 2 grams per tonne (at the lower part of New Britannia) to 3.5 grams per tonne (at the upper part of New Britannia).
8 Mineral reserves and resources were initially estimated using metal price assumptions that vary marginally over the assumptions used to estimate mineral reserves at Lalor. In the Qualified Person’s opinion, the combined impact of these small variations does not have any impact on the mineral reserve and resource estimates.

5 Pen II mineral resources are estimated using a minimum NSR cut-off of C$75 per tonne.
6 Watts and Pen II mineral resources were initially estimated using metal price assumptions that vary marginally over the assumptions used to estimate mineral resources at Lalor. In the Qualified Person’s opinion, the combined impact of these small variations does not have any impact on the mineral resource estimates.
