Canada (and US) likely has half the world’s remaining precious metal deposits (especially silver). This is why mining has been “slow-walked” for nearly 100 years now (since around 1909-1913). People forget that most of Central Canada was locked up as private “Hudson Bay Company” (Crown-controlled) until the late 1800s. Ref “Mining Acts” of 1866 and 1872: https://en.m.wikipedia.org/wiki/General_Mining_Act_of_1872

Speculated reason for large deposits remaining is historical lack of access to North and South America mining sites compared to Africa, Mid-East, Europe, and Asia (Per our currently published history).
