St George Mining finds more EM nickel-copper sulphide drilling targets at Mt Alexander

  • 25 February

Growth focused Western Australian nickel company St George Mining Limited (ASX: SGQ) has reported further outstanding exploration results from ongoing work at its flagship Mt Alexander nickel-copper sulphide project, located in the north-eastern Goldfields.


HIGHLIGHTS:

West End Prospect lights up with moving loop electromagnetic (MLEM) survey: 

  • Multiple EM anomalies identified at West End Prospect by high temperature SQUID MLEM survey 

  • These new EM anomalies are located to the north-northwest of the high-grade nickel-copper sulphide discoveries at the Investigators Prospect and are coincident with the western extension of the Cathedrals mineralised trend

Downhole electromagnetic (DHEM) surveys at Investigators record multiple new EM anomalies:  

  • Multiple off-hole EM anomalies identified in several of the deeper drill holes completed at Investigators in late 2019 

  • New EM anomalies are excellent targets for further down-plunge extensions of the shallow deposits at Investigators

Magnetotelluric (MT) survey to commence shortly at Mt Alexander:

  • MT survey is an electromagnetic geophysical survey that records the Earth’s electric and magnetic fields, resulting in the identification and mapping of geological structures and stratigraphy to very significant depths 

  • The MT survey at Mt Alexander is designed to map the structures and ultramafic intrusives at the Cathedrals Belt to a potential depth of 5km and will also identify any repetitions of similar structures and ultramafic stratigraphy in the under-explored tenements adjacent to the Cathedrals Belt  

  • Data from the MT survey will assist in planning deeper drilling at the Cathedrals Belt to further investigate the down-plunge extensions of the shallow nickel-copper sulphide deposits in the Belt

Multi-rig drill programme to test large number of EM targets:  

  • A combined reverse circulation (RC) and diamond drill programme will commence shortly to test a large number of EM targets in the Cathedrals Belt and to complete resource definition at the Stricklands Prospect  

  • In addition to the new West End EM anomalies and deep DHEM anomalies at Investigators, drilling will test new EM anomalies at the Fish Hook Prospect and over 30 EM anomalies at the Investigators Prospect that were identified in 2019 and remain untested by drilling

  • With all EM conductors tested in the Cathedrals Belt to date confirmed as nickel-copper sulphides, the upcoming drilling has the potential to significantly increase the volume of high-grade mineralisation at Mt Alexander

Metallurgical testwork continues: 

  • Testwork in progress on sulphides from metallurgical hole MAD177 to optimise recoveries of nickel, copper, cobalt and PGEs 

  • Preliminary test work produced a nickel concentrate that included 13.5g/t PGEs, including 9g/t Palladium and 1.2g/t Rhodium  

  • Both of these precious metals are trading at or about record highs with Palladium at more than USD2,600/oz and Rhodium at more than USD11,000/oz
