“Over one million tonnes of cobalt from 1773- 1898”

”The Skuterud Mine produced over one million tonnes of cobalt from 1773- 1898, and at the time was both the world’s largest cobalt producer and the largest company in Norway.”

Can you believe, almost 10000t of cobalt every year ?
Is it wrong?
And in the IPO prospectus, “The Skuterud deposits are metasomatic-hydrothermal, Cu-Co deposits in Modum municipality. The main part of the disused Skuterud mines are located in the southernmost 3 km of a 12 km long, 100–200 m wide, mineralised zone called a fahlband. There were five mined areas and three other deposits. Mining occurred from 1773 to 1898, until ore reserves rapidly decreased. Total production is estimated as 1 million tons with 0.1–0.3 % Co, up to 2.0 % Cu and Au up to several parts per million locally.”
How do you think about it ?
