The Nagambie Mine site is underlain by the Shepparton Formation, which is typically composed of fine to coarse grained, well to poorly-sorted sand and gravel “stringers”. To the west of the Nagambie Mine site, the Shepparton Formation is underlain by the Calivil Formation which includes sub-angular to sub-rounded fine to coarse grained, poorly sorted sand and gravel deposits in a well defined palaeochannel or deep lead. The deep lead runs north-south and its eastern verge is likely to reach in the western portion of the Nagambie Mine site.
Nagambie Resources proposes to develop these sand resources, initially by extending the West Pit further west on Nagambie’s freehold land. Drilling undertaken by Nagambie in this area has indicated the presence of a significant sand and gravel resource that is suitable to use as concrete sand, packing sand, filter sand and decorative pebbles. Planned additional testing will indicate if the sand resources are suitable for use as a silica sand in glass manufacturing.
