Workforce
As of September 2023, the operation employed over 1,000 people (520 full-time, 560 contractors). In 2022, it sustained over 600 jobs annually, expected to double to 1,200 during expansion construction.
Overview
The Island Gold District comprises the Island Gold underground mine and the adjacent Magino open-pit mine in Ontario, Canada. It is undergoing a significant multi-phase expansion to increase production and extend mine life.
Production
For 2025, the district produced 250,400 ounces of gold. 2026 guidance is 290,000-330,000 ounces. Post-2028 expansion, annual production is expected to average 534,000 ounces over the first 10 years.
Processing
Currently, ore from the Island Gold underground mine is processed at the 1,200 tpd Kremzar mill, with some at the Magino mill. The Kremzar mill is expected to be decommissioned in 2025. All ore from both mines will then be processed through an expanded and centralized Magino mill, which is being expanded to 20,000 tpd with a new parallel circuit.
Equipment
The Island Gold underground operation is accessed via a ramp system. A new shaft is being installed to an initial depth of 1,379 metres, designed for an ultimate depth of 2,000 metres. A new paste plant for backfill is also included in the expansion.
Expansion
The mine is undergoing a significant, multi-phase expansion, including the Phase 3+ Expansion to be completed in late 2026, doubling underground throughput to 2,400 tpd. A larger district expansion to 20,000 tpd is expected by 2028, increasing underground mining rates to 3,000 tpd and open-pit processing to 17,000 tpd. The adjacent Magino mine was acquired in July 2024 and is being integrated to form the Island Gold District, utilizing Magino's larger mill and tailings facility. A February 2026 study outlines a US$542 million investment for milling capacity upgrades.
