Ground investigations have progressed well. The critical data so far has been included in the reports that will be released in draft at the end of August. The extracted drillcore has shown expected geology, such as Awhitu Sand Formation in BH-M03 (drillcore image below). Samples are due to be sent to a laboratory for testing and ground water monitoring will continue beyond the completion of the programme.
