Top soil to be used as bund wall protection with 3m bench from the pit crest
Overburden waste to be utilised for construction of ROM pad, road and other earthworks
Low grade material to be stockpiled inside pit area
Medium grade and high grade ore to be stockpiled separately on ROM pad

Drill from Stage 1 to Stage 4.
Over 300 holes for at least 4000m in total
Drill test both high grade layers and +2m.
0.25m depth sampling including 0.5m either side of ore
Submit in pit ore zone samples to NTEL for assay
Retain samples in ore below pit for future assay
