Name of the Project
KSM gold/copper/silver project.

Location
Northern British Columbia, Canada.

Project Owner/s
Seabridge Gold.

Project Description
An updated prefeasibility study (PFS) has shown a considerably more sustainable and profitable mining operation than its 2016 predecessor.

The project now comprises 33 years of all openpit mining operation that includes only the Mitchell, East Mitchell and Sulphurets deposits.

The updated PFS proposes mining only 25% of the KSM resource inventory and does not include material from the copper-rich Kerr and Iron Cap deposits. The primary reasons for the improvements in the plan arise from the acquisition of the East Mitchell openpit resource and an expansion to planned mill throughput.

The updated PFS has increased the mill throughput from 130 000 t/d to 195 000 t/d. Over the entire life-of-mine, ore will be fed to a flotation and gold extraction mill. The flotation plant will produce a gold/copper/silver concentrate for transport by truck to a nearby seaport at Stewart, British Columbia, for shipment to Pacific Rim smelters. The KSM operation will produce an average of 1.4-million ounces a year of gold, 251-million pounds a year of copper, 3.8-million ounces a year of silver and 2.1-million pounds a year of molybdenum. A separate molybdenum concentrate and gold/silver doré will be produced at the KSM processing facility.

Potential Job Creation
Not stated.

Net Present Value/Internal Rate of Return
The net present value has risen from an after-tax net present value, at a 5% discount rate, of $1.5-billion in the 2016 PFS to US$7.9-billion in the updated PFS. The after-tax internal rate of return has risen from 8% to 16.1%. The payback period has fallen from 6.8 years to 3.7 years.

Capital Expenditure
Total cost of the project has been reduced from $10.5-billion in the 2016 study to $9.6-billion in the updated PFS, with increases from inflation and mill expansion being wholly offset by the elimination of block cave mining from the PFS plan.

Planned Start/End Date
Not stated.

Latest Developments
None stated.

Key Contracts, Suppliers and Consultants
