• Updated 2026-2030 five-year average annual gold production to 185,000 ounces from continued strong mill throughput rates at New Britannia and higher gold recoveries at Stall, representing a 37% increase in total gold production from an additional 250,000 ounces produced over the same five-year period in the 2021 technical reporti.
  • Total life-of-mine gold production increased by 60% to 2.8 million ounces from 1.8 million ounces in the 2021 technical reporti.
  • Updated 2026-2030 five-year average gold cash costsii to $821 per ounce and five-year average sustaining cash costsii to $1,379 per ounce, maintaining industry leading operating margins.
  • Snow Lake mineral reserve estimates increased to 27 million tonnes containing 2.0 million ounces of gold, representing a 38% increase in tonnage from the January 1, 2026 mineral reserve estimate.
  • Snow Lake mineral resource estimates increased to 21 million tonnes containing 1.5 million ounces of gold, representing a 26% increase in tonnage from the January 1, 2026 mineral resource estimate, despite significant resource-to-reserve conversion.
  • Life-of-mine plan based on reserve estimates and represents a conservative view based on Hudbay’s historical high resource-to-reserve conversion rate of 90%iii and ongoing exploration activities.
  • 1901 exploration and development activities are progressing well, and the project is on track to achieve full production in late 2027.
  • Stall hot tailings project is underway and is expected to be commissioned in early 2028, resulting in further increases in gold and silver recoveries.
  • Longer-term production profile enhancement and reserve mine life extensions expected from continued conversion of mineral resources at Lalor, exploration at 1901 to unlock gold potential, reprocessing of Anderson tailings in Snow Lake, and additional exploration at existing satellite deposits in pursuit of a new anchor deposit.
  • The Britannia Gold Project presents a new anchor deposit opportunity to meaningfully add gold production and significantly extend mine life well beyond current reserves.
