St George Mining intersects further high-grade nickel-copper sulphides at Mt Alexander Project

St George Mining Limited (ASX:SGQ) (FRA:S0G) has announced further significant exploration results at its flagship Mt Alexander Project, with high-grade nickel-copper sulphides intersected 125 metres down plunge in the first step-out hole for the MAD199 discovery. The drill hole MAD201 was a large step-out from the 10.96 metres nickel-copper sulphides intersected in MAD199 to test for extension of mineralisation at depth, and intersected a 16-metre-thick intrusive unit from 421 metres downhole that included a 2.4 metre interval of nickel-copper sulphides from 434.6 metres downhole. In addition, three very strong off-hole electromagnetic (EM) conductors were identified from the downhole EM survey in the drill hole, with modelled conductivity of 120,400 Siemens, 30,000 Siemens and 23,000 Siemens, respectively. All the conductors are interpreted to have a massive sulphide source and are up-dip from the mineralised interval - suggesting the potential for significant nickel-copper sulphides to be present along the 125-metre plunge from MAD199 “Growing the footprint of high-grade mineralisation” St George Mining executive chairman John Prineas said: “The mineralised intersection in MAD201 is an excellent result for the large step-out from the MAD199 discovery as it has identified a potential 125 metres down-plunge extent of mineralisation. “The strong EM conductors identified from the downhole EM survey in MAD201 further support the likelihood of additional mineralisation being present in this area. “Our systematic exploration approach of the large intrusive mineral system at the Cathedrals Belt is now delivering tangible breakthrough results. “We are confident that further drilling will continue to grow the footprint of high-grade mineralisation at the Cathedrals Belt coinciding with strong capital markets focus on identifying the next generation of nickel sulphides supplies.” Drill core from the mineralised interval in MAD201 showing massive sulphides as well as stringer and disseminated sulphides. Drilling of gravity target commences A high-resolution ground gravity survey was recently completed over West End and Investigators, with a number of gravity highs identified that are interpreted as prospective for nickel-copper sulphides. The new gravity targets are favourably located along the mineralised trend of the Cathedrals Belt, supporting the potential for the targets to represent intrusive rocks and massive sulphides. The largest of the ‘bulls-eye’ gravity highs is located at West End and has dimensions of around  100 metres x 200 metres. Drilling of MAD202 is underway, which has a planned downhole depth of 450 metres, and has been designed to test this large gravity target.
