Production
Production overview - 2025: silver 8724996 oz, gold 59349 oz, lead 18213 t, zinc 51300 kt; 2024: silver 8480877 oz, gold 55275 oz, lead 18320 t, zinc 51288 t.
Processing
The mine operates an ore concentrating mill. The processing method involves a conventional flotation concentrator that produces a gravity gold concentrate, a silver concentrate, a zinc concentrate, and a precious metals concentrate. In 2024, 46% of the tailings were reused as backfill in the underground mine.
Expansion
In January 2026, the U.S. Forest Service approved a five-year plan of operations for the Greens Creek Surface Exploration Project. This project will explore for mineral deposits including silver, gold, lead, and zinc on Forest Service lands on Admiralty Island. Hecla Mining is also investigating the economic potential of recovering and reprocessing critical minerals from the mine's tailings, which contain silver, gold, zinc, lead, copper, and other minerals. There is also an early-stage project for the expansion of the dry-stack tailings facility.

Production
The Phase 1 concentrator produced its first concentrate on November 18, 2025, and is now in its ramp-up phase. The first sale of concentrate was made to Northam Platinum in the fourth quarter of 2025. The concentrator is initially processing lower-grade development ore and is expected to transition to higher-grade ore in the second quarter of 2026. By mid-2026, the concentrator is expected to operate at 80% of its capacity. Production guidance for 2026 has not yet been issued.
Processing
The mine is being developed in three phases. The Phase 1 concentrator has a milling capacity of 770,000 tonnes per annum. The Phase 2 expansion includes a new 3.3-million-tonne-per-annum concentrator module, bringing the total processing capacity to 4.1 million tonnes per annum. A potential Phase 3 expansion would increase processing capacity to 10.7 million tonnes per annum.
Equipment
Underground mining is conducted using mechanised methods, including long-hole stoping and drift-and-fill. Key infrastructure includes Shaft #1, which provides initial access for workers and materials. Shaft #2 is planned to be the main production shaft with a hoisting capacity of 8 million tonnes per annum. Shaft #3 is expected to be operational by April 2026, increasing the mine's total hoisting capacity five-fold to 5.0 million tonnes per annum, which will support the Phase 1 ramp-up and Phase 2 expansion. The mine also has a 5-megawatt solar power facility that was completed in the first quarter of 2025.
Expansion
Project development for the Phase 2 expansion is underway, with a targeted completion in the fourth quarter of 2027. The Phase 2 expansion is expected to increase average annual production to approximately 450,000 ounces of platinum, palladium, rhodium, and gold (3PE+Au), plus over 30 million pounds of nickel and copper. A Preliminary Economic Assessment has been completed for a future Phase 3 expansion, which would further increase annual production to over 1 million ounces of 3PE+Au. A $700 million senior project finance facility for the Phase 2 expansion has been signed.

Approximately 6,000 full-time employees as of February 2025.
Production
Production overview - 2023: copper 393551 t; 2022: copper 333497 t.
Processing
The complex operates multiple concentrator plants. The process design for Phase 1, 2, and 3 concentrators is similar, utilising a commonality of spare parts. Key equipment includes energy-efficient HIGmill regrind mills, Larox PF 60 Series concentrate filters, and TankCell flotation cells from Metso Outotec. The mills are driven by WEG medium voltage VSDs and high voltage motors. A new, on-site direct-to-blister flash smelter with a capacity of 500,000 tonnes per annum commenced operations in late 2025. This smelter is the largest in Africa and is designed to process the majority of the copper concentrate produced by the complex.
Equipment
The underground mining fleet includes 65-tonne payload Minetruck MT65 S haulers, 18-tonne payload Scooptram ST18 S loaders, Boomer 282 face drilling rigs, and Simba E70 S production drilling rigs supplied by Epiroc. Additional underground equipment has been sourced from Sandvik and Normet Oy.
Expansion
The Phase 3 concentrator was completed in June 2024, increasing the total design processing capacity to 14.2 million tonnes per annum. This expansion is expected to increase annual copper production to over 600,000 tonnes. A Phase 4 expansion is planned for later in the decade, which will involve another 5.0 Mtpa concentrator, bringing the total processing capacity to 19.2 Mtpa. A 2023 Preliminary Economic Assessment includes a mine life extension to 42 years, incorporating four new underground mines (Kamoa 3, 4, 5, and 6).
