ABSTRACT:Middle Island Resources Limited (Middle island, MDI or the Company) is pleased to update shareholders on the status of diamond drilling and ore sorting trials on the Two Mile Hill tonalite deeps deposit at the Company’s 100%-owned Sandstone gold project in WA. The Two Mile Hill tonalite deeps deposit is located 4km north of the Company’s 600,000tpa Sandstone gold processing plant. The deposit comprises an Exploration Target of 24Mt to 34Mt at 1.1g/t to 1.4g/t Au (0.9M-1.5Moz of gold - refer ASX Release 29 November 2017) situated between 140m (the base of quantified open pit resources) and 700m vertical depth, below which it remains open. The potential quantity and grade of an Exploration Target is conceptual in nature, as there has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. Initial mineralogical assessment, which involved the assaying of a series of hand-sorted composites of quartz vein material and un-veined tonalite, suggested that >99% of the gold is hosted in the quartz veins (refer ASX release 11 October 2017). As such, an ore sorting study was initiated on gold mineralised material sourced from the Two Mile Hill tonalite deeps deposit. The results of initial trials suggest that ore sorting can deliver a 185%-257% increase in grade, with gold recoveries in excess of 93%, and 64% of the sorter feed material being rejected (refer ASX Release 15 January 2018). Given the considerable encouragement derived from indicative ore sorting testwork,
