MESQUITE GOLD MINE

AVERAGE 130,000 OZ/YEAR FOR LAST 10 YEARS

Equinox Gold completed its acquisition of the Mesquite Gold Mine on October 30, 2018, bringing immediate production and cash flow to the Company and transforming Equinox Gold from a developer to a producer. Mesquite is an open-pit, run-of-mine (“ROM”) heap leach gold mine located in Imperial County, California with a long history of successful operations. The mine has produced more than four million ounces of gold since it commenced operations in 1985 with average annual gold production of approximately 130,000 ounces over the last 10 years.

* Resources are inclusive of Reserves.

MESQUITE GOLD MINE

Mining is performed using owner-operated conventional truck and shovel open-pit mining methods and ROM ore is hauled directly to the leach pad for processing.

For 2021, Equinox Gold expects Mesquite to produce between 130,000-140,000 oz of gold at AISC of $1,375-$1,425 per ounce of gold sold. During Q3 2021, the Company transitioned from waste stripping to mining oxide ore from the Brownie deposit. Ore tonnes and ounces placed on the pad were close to double Q2 2021 quantities, resulting in a significant decrease to processing and G&A costs per tonne, which are calculated based on tonnes stacked. The Company has also had significant exploration success at Mesquite resulting in conversion of resources to reserves and mine life extension, as outlined in the September 8, 2021 press release.
