Formation Metals has commenced the construction of mine site earthworks at its cobalt project, located in east-central Idaho, US.

The firm has started portal bench mine site earthworks, along with concurrent mill and concentrator site earthworks.

DAHLE CONSTRUCTION has mobilised earth moving heavy equipment and established a crushing facility nearby to provide raw materials for construction.

Formation Metals project and construction manager JDS Energy & Mining is conducting a review on the earthworks quantities of materials required to reduce time schedules and cost.

The firm has also sent a proposal package for vendors for the design, supply and installation of the cobalt beneficiation plant, which is expected to commence in the second half of August 2011.
