Annual Report for ML 22934 Groundrush for the period 14 September 2014 to 13 September 2015

Abstract

A total of five air core holes were drilled, totalling 437 meters, targeted into the low quartz veined rise. In order to maximise the sample size collected for analysis, each meter was collected directly into a green plastic bag, and a sample collected by spear. Average sample size was 922grams. Water became a problem at depth within the quartz vein zone, restricting the size and quality of sample collected. Drilling intersected massive dolerite, followed by a broad contact zone of clay and indeterminate totally altered rock, with zones of broad quartz veining, emerging into very felsic coarse grained greywacke rock commonly with a granitic appearance. Petrology carried out on a sample of the greywacke confirmed the greywacke-arkosic nature of the sediment. Quartz veining commonly displayed haematitic staining and cockscomb textures and although the width of individual quartz veins is not possible to be determined from aircore chips, the zone appeared to be a more intense veining, rather than a single massive buck quartz blow. Correlation between the surface trace of quartz veining, and between holes suggests that the quartz veining and alteration contact zone is vertical to steeply westerly dipping, and varies in width 20 - 30 true width. The percentage of quartz veining within the clay alteration contact zone varies between sections. Although haematite staining is intense through the quartz-clay-alteration zone, there is no other indication of mineralisation
