(Kitco News) - Hudbay Minerals (TSX: HBM) said yesterday that its mineral reserve growth replaces close to 100% of 2021 mining depletion and extends the mine life at each of Constancia and Snow Lake by one year to 2038.

The company added that annual copper production from Constancia is expected to average approximately 105,000 tonnes over the next seven years, a 35% increase from 2021 levels.

Importantly, Hudbay noted that annual gold production from Snow Lake is expected to average over 180,000 ounces over the next six years, a more than 55% increase from 2021 levels.

Moreover, the company pointed out that positive scoping study on underground mining potential at Constancia Norte results in an initial inferred mineral resource estimate of 6.5 million tonnes at 1.2% copper, adding potential to increase copper production at Constancia after 2028.

Hudbay also said that successful exploration at Lalor and the 1901 deposit in Snow Lake further increases the size of the base metal and gold zones at these deposits; contained gold in Snow Lake's mineral reserve estimates increases by 218,000 ounces to 2.4 million ounces.

The company added that ongoing exploration drilling at Copper World in Arizona has the potential to extend known mineralization on private mining claims; preliminary economic assessment remains on track for completion in the first half of 2022.

"We have continued to grow our copper and gold mineral reserves and resources through successful exploration in Peru, Snow Lake and Arizona," stated President and CEO Peter Kukielski. "While we already have a solid production growth profile for many years to come, our exploration efforts over the past year have been successful in replacing what we have mined, adding reserves to our life of mine plans and expanding our resource base to position us for additional long-term reserves growth."

Hudbay is a diversified mining company primarily producing copper concentrate (containing copper, gold and silver), zinc metal and silver/gold doré. Directly and through its subsidiaries, Hudbay owns three polymetallic mines, four ore concentrators and a zinc production facility in northern Manitoba and Saskatchewan (Canada) and Cusco (Peru), and copper projects in Arizona and Nevada (United States).
