ML 32039 Mt Karangahake, Coromandel Peninsula : Report on exploration for the period August 1985 to March 1986

This report summarises work carried out in the area, including geochemical sampling, resistivity surveys and diamond drilling. The exploration target consisted of zones of silicification and quartz stockwork veining. Surface rock chip sampling showed that these zones contain anomalous gold values. Resistivity surveys were used to map the distribution and intensity of silicification and to determine its depth extent as a guide to the position of major conduits or root zones. Drilling targets were selected on the basis of the resistivity results conbined with rock geochemistry, and observed geology. Five diamond core holes were drilled. The drilling results showed that the silicified stockwork zones do not contain ore grade gold values.
