Annual Report EL 31406 Marantha Farm 21 February 2018 to 20 February 2019

Abstract

This report describes a short program of RAB drilling undertaken on 14 July 2018 on Maramatha Station which is held by Darwin Christian Ministries Incorporated. The objective of the exercise was to identify shallow water resources. The Area of Interest is located about 93kms southeast of Darwin and can be reached by following the Arnhem Highway to the Maramatha Homestead turnoff 64kms east of the Stuart Highway Arnhem Highway Junction. The total useable area associated with and extending beyond the Area of Interest covers 86ha. The work completed was the drilling of a total of six shallow holes varying from 14.5 to 23.0m depth. The material recovered from the drill holes was logged and is predominately unconsolidated sediments ranging from clay to gravel sized material. Occasionally the holes encountered gravel lag beds and bedrock of meta-siltstone. The bedrock is interpreted to belong to the early Proterozoic Koolpin Formation. The presence of water was identified in three of the drill holes based upon the material recovered being either damp or wet. The shallowest depth at which wet sediment was recovered was at 14.Sm in two of the drill holes. The results of the drill program confirm that the area investigated is underlain predominantly by sediments of alluvial origin as indicated on the government geological maps. Drilling indicates that within the area these sediments have a minimum depth of 14.Sm and a maximum depth in excess of 23.0m. Water was encountered during drilling at depths as shallow as 14.5m
