a Quebec-based geophysical consulting firm carried out a series of ground magnetometer and gravity surveys over several main targets including the Gagnon and Elizabeth taconites and over the James, the Houston, the Malcolm-1 and the Howse direct shipping (DSO) iron ore deposits.
LIM is also on track to complete new and initial mineral resource estimates on the Malcolm deposit (nearby Houston), the historic crushed ore stockpiles in both Quebec and Labrador and its first inferred mineral resource estimate on the Elizabeth Lake Taconite.
An initial mineral resource estimation will also be provided on the Elizabeth Lake Taconite.
