Legacy Iron Ore (ASX:LCY) said the grade control drilling program of 5,838 metres comprising 223 holes at its Mount Celia project in Western Australia was completed during May, and the data is being reviewed, according to a Tuesday Australian bourse filing.

The company has commenced drilling north of the Kangaroo Bore deposit to support waste rock characterisation studies, with planned intersections into ore zones.

Data from the recent drilling programs is being incorporated into an updated mineral resource estimate for Mt Celia, the filing added.

The company added that metallurgical test work and feasibility studies are progressing to evaluate the potential development of an independent on-site processing facility, and the studies will provide essential inputs for ore reserve estimation.
