Geophysics and Drilling Collaborations Final Report Deep Diamond Drilling Proposal Carrara Project -EL 30665

Abstract

Teck Australia completed a single diamond drill hole into an interpreted sub-basin within the Carrara Project (EL 30665) with the objective of detecting sulphidic Paleoproterozoic stratigraphy, believed to be prospective for Shale-Hosted Massive Sulphide Zn-Pb-Ag mineralization, interpreted at a depth of 500m to 750m defined by a conductive horizon identified in an extensive AMT survey completed in 2015. The interpreted 4th order sub-basin was identified from magnetics, gravity, and proximal outcrop and was placed proximal to the NE trending Little Range Fault, considered a major basin bounding extensional fault, and a NW trending 'transform' structure. The drill hole, CRDD001, was drilled between the 10th and 26th October 2016, and was completed to a depth of 800.42m terminating within South Nicholson Group sediments after encountering difficult drilling conditions. The target Paleoproterozoic sediments were not intersected, indicating the identified NW trending structure was likely reactivated post Cambrian. The AMT conductive horizon is likely coincident with a large saline aquifer within a porous sandstone host. CRDD001 was the only effective drill hole within the prospective covered Lawn Hill Platform immediately south of the Carrara Range, and has aided the geological understanding of the area.
