Impact Minerals Encounters Thick Widths of Silver and Base Metals
THE DRILL SERGEANT: Impact Minerals announced interim results from the first two follow up diamond drill holes at the high-grade gold-silver discovery at the Silica Hill prospect, part of the company’s 100 per cent-owned Commonwealth project north of Orange in New South Wales.
Impact Minerals said the drilling returned thick widths of stockwork and narrow veins spaced 30 centimetres to 50cm apart that contain extensive visible silver minerals and zinc, lead and copper sulphides.
The company stressed that the nature and extent of these minerals have been estimated visually and with a hand held XRF instrument that is not capable of detecting gold, however previous results indicate that gold is likely to be present in places.
Hole CMIPT063 tested a modest north-east extension of the mineralised zone and returned a 116 metre thick zone of veins from 57m down hole comprising a lower 70m thick zone of silver and base metal-rich veins and an upper 40m thick zone of silver-rich veins.
The lower zone comprises veins of zinc, lead and copper sulphides that are up to a few centimetres thick and spaced every 50cm to 1 metre down hole.
There are thicker veins up to 20cm thick in places, which, although narrow, contain high grades of zinc and lead (up to 20%), good grades of copper (up to 2%) and very high to exceptional grades of silver (commonly in the hundreds of grams and up to 7,000 g/t silver).
Accessory metals such as molybdenum, antimony, tin, bismuth and arsenic are also present in measurable amounts.
“The nature of the veins and the unique metal assemblage are interpreted to be characteristic of the edges of a high-grade ‘feeder zone’ to the large mineralised system at Silica Hill,” Impact Minerals said in its ASX announcement.
“This is the first indication of this type of feeder vein at Silica Hill and which were postulated to be present in a previous announcement by Impact.
“The feeder zone is interpreted to possibly extend for a further 1,000 metres to the north east.”
