Equinox Gold Corp. (TSX: EQX, NYSE American: EQX) is pleased to provide an update on construction and commissioning progress at its Greenstone Project in Ontario, Canada. The Greenstone Project is being developed as a 60/40 partnership, respectively, by Equinox Gold and Orion Mine Finance Group, and will be one of the largest gold mines in Canada, with average annual gold production of more than 400,000 ounces over the first five years and more than five million ounces of gold produced over its initial 14-year mine life.

Greenstone Project construction progress is documented weekly in a photo gallery on Equinox Gold’s website at www.equinoxgold.com and select photos are included in this news release.

Recent Highlights (at November 10, 2023 unless otherwise noted)

  • Schedule – The Greenstone Project is 96% complete. Pre-commissioning1 activities are ongoing in most of the main process plant areas, including the crushing and grinding circuits, and wet commissioning1 is underway in select areas.
  • Budget – The Greenstone Project remains on track for a total spend of $1,225 million. At September 30, 2023, $1,087 million (89%) of the budget had been spent (100% basis).
  • Facilities completed – The realigned 4.7 km of Highway 11 was opened to traffic in August and the power plant was turned over to the operations team in September, both ahead of plan. The permanent effluent water treatment plant, truck shop, warehouse, sewage treatment plant, potable water treatment plant, pit and plant site fuel stations, reagent storage, site mixed emulsion (explosives) plant and natural gas pipeline to site were previously turned over and are all in operation.
  • Construction progress – All major equipment is now on site and construction is 96% complete. The focus is on remaining electrical and instrumentation installations in the process plant. In October, the tailings storage facility (“TSF”) was completed to planned elevation. Commissioning of the TSF is on track for December 2023.
  • Commissioning – Pre-commissioning activities are ramping up in coordination with final construction activities, with systems checks underway at the crusher, ball mills, ore storage dome and high-pressure grinding rolls (“HPGR”) areas. Wet commissioning has commenced at the leach tanks and in the crusher area.
  • Pre-production mining – The third Epiroc Pit Viper 235 drill has been commissioned. Commissioning of CAT 793F haul trucks 9 and 10 is underway, and haul trucks 11 to 14 and the LeTourneau 1850 loader will be ready for service in early Q1 2024. More than 15 million tonnes of material has been moved to date and build-up of the ore stockpile is ahead of plan and on track to exceed the 800,000 tonnes start-up target.
  • Operational readiness – Operational readiness activities and hiring are progressing in-line with plan. An update on Greenstone 2024 operating costs and production estimates will be reported in connection with the Company’s annual production and cost guidance in Q1 2024.

Greg Smith, President & CEO of Equinox Gold, commented: “With the Greenstone Project 96% complete and the power plant fully operational, the priority is now on completion and commissioning of the process plant, commissioning of the TSF and ramp up of mining and operations. The project continues to advance on budget and on schedule. We look forward to pouring gold in the first half of 2024 and then achieving commercial production.”

1. Pre-commissioning is the completion of the construction phase for each equipment and system, including the completion of all inspection test plans, confirmation of all motors and rotations, and confirmation of all signals from equipment and instruments to the control systems. Wet commissioning includes a dry run of equipment, running motors, vibration and temperature monitoring, loop tests, and testing of safety devices, interlocks and speed control. Hot commissioning follows wet commissioning with the introduction of reagents and ore.
2. Total Recordable Injury Frequency Rate is the total number of injuries excluding those requiring simple first aid treatment.
