| ABSTRACT: | A diamond core extension to drill hole MSDD156 was completed at the Two Mile Hill tonalite deeps deposit during September. The 230.9m NQ2 diamond core extension on MSDD156 (730m total depth) comprised the remaining drilling available under Round 14 of the WA Government’s Exploration Incentive Scheme (EIS) grant, following a successful variation request. The original MSDD156 generated an intercept of 415.2m at 1.34g/t Au from the commencement of coring at 83.7m depth to the end of the hole at 498.9m. This broader intercept ended with an intersection of 66.9m at 3.27g/t Au from 432m to end of hole at 498.9m, finishing in strongly mineralised material. Details of the original hole can be found in the Company’s ASX release dated 7 June 2017, and updated in an ASX release dated 11 October 2017. The primary purpose of the MSDD156 extension was to establish to what extent the higher grade zone persisted with depth. The initial 95m of the extension was visually strongly mineralised, characterised by intense sheeted quartz veining and associated sericite-carbonate alteration, including logged instances of visible gold. At 599m depth the hole transitioned into basalts comprising the western (hangingwall) contact of the tonalite. Navigational drilling (during which there is no core recovery) was employed to bring the hole back into the tonalite. A further 90.1m of more weakly quartz-veined tonalite was then intersected before the hole once again deviated into the hangingwall basalts. As this process would likely be repeated, given the expense of navi-drilling and having reached the anticipated limit of the EIS grant funding, the hole was terminated in basalt at 730m depth. | |
