Treaty Creek Terminal technical

"Seabridge Gold announces substantial completion and successful energization of the Treaty Creek Terminal"

hydroelectric power technical

"means KSM has access to reliable, clean and economic hydroelectric power"

Hydroelectric power is electricity generated by using the energy of moving water—typically from rivers or reservoirs—turned through turbines to make power, like a waterwheel driving a mill. It matters to investors because hydro projects are large, long-lived assets that can produce steady, low-cost electricity and predictable cash flow similar to a toll bridge, but they also carry risks from construction expense, water availability, regulation and environmental impact.

critical minerals financial

"The Project can serve as a significant long-term source of critical minerals"

Materials needed to build modern technologies—like batteries, electronics, renewable energy systems and defense equipment—that have few easy substitutes and often come from a small number of countries or mines. Investors care because their supply can be disrupted, expensive or slow to increase, which affects the cost, availability and growth prospects of companies and industries that rely on them; think of them as critical spare parts for the global economy.

Golden Triangle technical

"principal assets are the KSM and Bronson Corridor projects in British Columbia's Golden Triangle"

Getchell Gold Belt technical

"Additional projects include Snowstorm in Nevada's Getchell Gold Belt"
