St George Mining Limited announced that drilling will start this week with the launch of a multi-faceted exploration campaign at its flagship high-grade Mt Alexander Project, located in the north-eastern Goldfields. DHEM surveys on the deeper drill holes completed last year identified 11 off-hole EM anomalies. The highest priority targets were identified from DHEM surveys in MAD185 and MAD192. Each of these holes intersected thick mafic-ultramafic units with disseminated nickel-copper sulphides ­ indicative of a fertile intrusive structure with prospectivity for higher grade mineralisation proximal to the hole. Five off-hole EM anomalies were identified from the DHEM survey in MAD185. Two of these are modelled with EM plates that have very strong conductivity of 33,100 Siemens and 14,225 Siemens, respectively. The DHEM survey in MAD192 identified two off-hole anomalies that have been modelled as EM plates with very strong conductivity of 55,550 Siemens and 26,000 Siemens, respectively. The MT survey completed at Mt Alexander in 2020 identified deep conductive features along the Cathedrals Belt. Deep drilling of these features confirmed the presence of thick intrusive-style rocks with potential to host significant nickel-copper sulphide mineralisation. The MT survey also identified a series of similar deep conductive features about 2km north of the Cathedrals Belt. These features are located on E29/548 (100% St George) and are parallel to the Cathedrals Belt. The shallow nickel-copper sulphides already discovered at Investigators have recorded strong yellow (conductive) responses in the data. Similar conductive responses were recorded on E29/548, which are shown as extending from surface to depths beyond 1km from surface. An aeromagnetic survey completed over E29/548 in 2016 by St George also recognised numerous east-west trending structures to the north of the Cathedrals Belt. A number of these features are coincident with the MT anomalies and may indicate deep seated structures. Drill holes MAD180 and MAD181 were designed to test the deep Investigators MT anomaly, which dips to the north-northwest, and the holes were therefore located to the north of the previous drilling. Both drill holes intersected mineralised ultramafic rocks approximately 500m to the north of Investigators. This supports the potential for other similar MT survey structures to host intrusive mafic- ultramafic units that are prospective for massive nickel-copper sulphide mineralisation. A MLEM survey ­ a ground-based EM survey ­ is planned for First Quarter 2021 over a priority area of E29/548 where deep structures were identified by the MT survey. The MLEM survey will search for conductive bodies at depth that may represent nickel-copper sulphides. This is the first EM survey that has been specially designed to investigate the east-west structures on E29/548. A drill programme for E29/548 will then be prioritised subject to a review of the survey results. MAD181 was drilled at Investigators to a downhole depth of 794.5m to test a broad conductive feature identified by the MT survey. The hole intersected a 49.45m thick mafic-ultramafic unit from 502.3m downhole. Petrographic analysis was completed on 7 samples of drill core across the intrusive interval. Polished thin sections of the core were examined using optical microscopy in transmitted and reflected light using an Olympus BH2 microscope. The petrography was completed by Dr Ben Grguric, principal of Mineralium Pty Ltd. and a mineralogist with industry leading credentials particularly in the field of nickel sulphide systems. The petrology has identified two main intrusive rocks, an upper leuconorite from 502.3m to 541m and a basal mela-olivine gabbronorite unit from 541m to 551.75m downhole. This is a suite of intrusive mafic and ultramafic rocks that is highly unusual in the Archean central Yilgarn where Mt Alexander is located.
