• Resumen

  • If Toronto-based Avalon Rare Metals' project near the Warren Township at Timmins, Ontario is given the go-head, it will need seasonal ice roadwork. Likewise, its calcium feldspar project is still in pre-feasibility stage and might need ice road support. The Nechalacho rare earth project at Thor Lake in the Northwest Territories is expected to complete permitting in 2015, while its lithium project at Separation Rapids, also in Ontario, is seeking investment for a demonstration plant and is preparing to restart permit applications with the state government.

    Once the ice thickens to 70cm over the entire road, trucks with very light loads are allowed to cross; when it becomes a metre thick along the entire road, it is strong enough for a Super B tanker (a truck hauling two tanks of fuel and weighing up to 42 tonnes) fully loaded with up to 50,000 litres of fuel to drive across, according to U-Haul. At this point, ice roads are officially open for the winter season. Depending on the region and seasonal temperatures, ice roads can last from a few weeks to several months.
