Diamond drill core assaying & structural interpretation MCN1297 and MCN1298 Lewis Prospect

Abstract

In 1972, the Northern Territory Geological Survey carried out an assessment or some gossanous quartz veins in an area about 3.2 kms southeast of Mount Wells Battery. This work showed that the veins carried the following; The vein system is described as more than 0.5 kms in length with a width ranging from 0.6 to 3 metres. Only small intervals of core were assayed for gold. The purpose of this report is to set out the results of assaying all the core from these holes for gold and arsenic and to give an opinion on the prospectivity of the area based on these results and on structural information gleaned from examination of the core, and aerial photographs. Three hundred and twenty nine samples, each representing about 1 metre length of diamond drill core were obtained from the 3 holes which were put down on the Mineral Claims. The highest gold assay obtained is 0.31 g/t and the highest arsenic value 7800 g/t. A statistical analysis of the arsenic assay results shows a strong result. There are two distinct populations of arsenic. The logical explanation is that one population represents the normal unmineralised rock, and the other population represents the mineralised rock. Bedding is not discernible in most of the core. However, what is present suggests that an anticline is present and that the vein represents a saddle reef. An air photograph study gives an antieline to the west of the Mineral Claims, but within Exploration Licence 5092.

Suggestions for further exploration are made.
