Exploration/Denial open hole rotary percussion drilling and surface sampling program Coronation Hill, NT, 1987.

Abstract

The report describes site clearance drilling and geochemical sampling to the north, south and east of the identified deposit at Coronation Hill. 32 holes were drilled to the north, and 32 to the south and east. These were to a depth of either 30m or 60m, and either vertical or angled at 60degrees. The areas were also covered with soil and rock chip sampling. The maximum value obtained in drilling was 0.315g/t, and most values were below the detection limit. Surface samples gave some anomalous values (to 6.1g/t Au), but these samples are believed to have come from transported material. The conclusion was that the sites were clear of mineralisation for development, but the report point out that the location of site facilities has since been changed, so that further site clearance work is needed. It is also possible that the deposit extends further south than is established from drilling.
