St George Mining is drilling a second diamond drill hole into the exciting Windsor X3 conductor at its 100%-owned East Laverton project after new modelling work suggested potential for nickel sulphides at greater depths.
The company’s first drill hole at Windsor X3 targeted a conductor at a downhole depth of 275 metres, however a downhole electromagnetic survey suggested the conductor was still below the bottom-hole depth of 340 metres.
Modelling of the latest down-hole survey results indicates a bedrock conductor about 160 metres further down. While the target has deepened, the new modelling suggests it is around twice the size of the originally modelled conductor at 600 metres x 225 metres.
The first hole at Windsor X3 intersected a number of ultramafic sequences, which are host rocks to magmatic nickel sulphides and provided more encouragement for drilling of a deeper target.
St George Mining Executive Chairman, John Prineas, said: “Our systematic exploration at Windsor is continuing to provide high priority targets for nickel sulphide mineralisation.
“The DHEM survey data has allowed for more definitive modelling of the Windsor X3 conductor and we are pleased to be able to immediately commence a further drill hole to test this large and exciting target.”
The Windsor X3 target is a high priority for St George because it is coincident with a magnetic feature and the edge of gravity feature. The conductor is also nearby magmatic nickel sulphide mineralisation intersected by previous drilling at Windsor, which included 30 metres at 0.31% nickel.
