RE:RE:SEA Maiden Resource Estimate There has been a ton of work since 2010 at KSM. KSM now hosts 76 million ounces of gold in the measured and indicated category plus 17.1 billion pounds of copper. Of this total 39 million ounces of gold and 10.1 billion pounds of copper are classified as proven and probable reserves.
In the inferred category, KSM hosts an additional 66 million ounces of gold and 33.2 billion pounds of copper.
Since the 2012 Preliminary Feasibility Study, an updated PFS was completed in 2016, a PEA in 2016 and a new PEA in 2020. Each successive engineering study showed a significant improvement in the project's economics. The most recent PEA showed a project with a US$9.6 billion after tax NPV. They have limited all their mine plans to date to the 2.4 billion tonnes that are already permitted in their proposed tailings facility.
Seabridge says it's now preparing a new PFS incorporating their recent acquisition of Snowfield that is expected to increase proven and probable reserves and further improve the project's economics.
In addition, KSM has successfully gone thru the environmental assessment process with permits in hand to commence construction.
