Iron ore is at a transition point. The same drivers of rising prices through 2019/20 went into reverse from mid-2021: supply constraints started to ease, but more significantly, the long awaited and much talked about cuts to Chinese steel production started to take effect, reinforcing our view that 2020/21 = peak hot metal production for …
Exposure. The iron ore mines in northern Sweden are the biggest underground iron ore mines in the world. They have been in operation for >100 years. All mining has been underground in Malmberget since 1923. The mine in Kiruna started going underground in the mid-1950s and from 1965 all mining has been underground.
