Seabee

High Grade Underground Mine

Seabee is located in Northern Saskatchewan, Canada approximately 125 kilometers northeast of the town of La Ronge. The Santoy underground mine has been in continuous commercial production since 2014. Commercial production at the Seabee underground mine commenced in 1991 and exhausted Mineral Resources in 2018. All ore is processed at the Seabee mill facility, which has been in operation since 1991. The Seabee mill facility produces gold doré bars that are shipped to a third party refinery. Access to the mine site is by fixed wing aircraft to a 1,275-meter airstrip located on the property. Equipment and large supplies are transported to the site via a 60-kilometer winter ice road, which is typically in use from January through March.

SSR Mining acquired Seabee on May 31, 2016 as a result of our acquisition of Claude Resources Inc. and filed a technical report in October 2017, which included the results of a Preliminary Economic Assessment evaluating an expansion of Seabee.

Highlights of Seabee include:

  • Mineral Reserves: Proven and Probable Mineral Reserves of 500,000 ounces of gold at an average grade of 10.17 g/t as at December 31, 2019.
  • Potential for mine life extension: Measured and Indicated Mineral Resources of 1,050,000 ounces of gold at an average grade of 10.61 g/t. Inferred Mineral Resources of 583,000 ounces of gold at a grade of 8.50 g/t. Mineral Resources are as at December 31, 2019. Mineral Resources are inclusive of Mineral Reserves.
  • Delivered record gold production: Produced a record 112,137 ounces of gold in 2019.
  • Exploration potential: Exploration programs in 2020 focused on expansion and definition of Santoy Gap Hanging Wall, and surface drill programs at the Seabee and Fisher properties following up on targets identified in 2019.

Seabee September 2017 Preliminary Economic Assessment Highlights:

  • Extends production profile: Estimated gold production averages 100,000 ounces per year over the period from 2018 to 2023, a 29% increase from 2016 production.
  • Expanded operating margins: Estimated life of mine cash costs of $548 per payable ounce of gold sold due to higher sustained throughput and an average mill feed grade of 8.51 g/t gold.
  • Improved processing plant performance: Estimated mill production averages 1,050 tonnes per day beginning in 2019, a 21% increase to 2016 throughput, with a projected 96.5% recovery.
  • Low capital investment: Development near existing infrastructure reduces projected total capex to $90 million, driving low all-in sustaining costs of $682 per payable ounce of gold sold.

The Seabee Preliminary Economic Assessment is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the Seabee Preliminary Economic Assessment will be realized.
