LBD001 drill hole - drill core observations, assessment of geochemistry and exploration implications

Abstract

This report is based on logging the LBD001 core, an assessment of whole rock and trace element geochemical data from drill-hole samples, and observations from an examination of nine petrographic sections from the core. The report summaries the main geological and geochemical observations and discusses the exploration implications arising from this data.

A brief geological log is given in Appendix I. Significant geological observations, including photographs of the core and comments arising from the logging are given in Appendix II. Results of petrographic examination of thin sections and a report on examination by Scanning Electron Microscopy of one polished thin section are presented in Appendix III A and B respectively. Assay data are given in Appendices IV and V and these data are discussed in Appendix VI.

The main focus of the report is on the nature of the mafic rocks intersected in LBD001 with the aim of determining what, if any relationship they have with the Antrim Basalts and to evaluate their exploration potential for magmatic Ni-Cu-PGE sulphide mineralization. Although the mafic rocks are the main focus other geological and geochemical features of significance are also briefly discussed.
