The proposal is to drill one deep well through the braided river gravel sequence at McLeans Island and install with 150 mm steel casing and 2 m stainless steel screens. The target termination criteria is the contact with lower permeability silt/clay/mudstone anticipated at the base of the high permeability quaternary braided river gravels.
There are currently no drillholes >150 m in the vicinity and geological interpretation at depth is from geophysical survey and knowledge of the regional geological formation sequence. The drilling and installation of this well will provide field evidence of the deeper geological sequence in the region and will generate a lot of interest from several third parties including agricultural, local council and academic groups. The completion of this deep well will be a notable addition to the resume of the successful bidder.
