First Nickel Inc. (TSX:FNI) announced it has updated its Lockerby Mine Plan incorporating optimized mining and updated costs.
As quoted in the press release:
The prior method of transverse mining has been changed to a longitudinal mining method. This change in mining method, together with optimizing the design of each level (eliminating crosscuts and lateral development, etc.) reduces required development, decreasing the tonnes of waste in the Mine Plan and supports opening multiple levels allowing a second bottom up mining front to be established.
