    re: somethings gotta be wrong...hmmnn Note the release on the 15th. June did highlight as a bold header "Intense native copper over 46m in New Discovery Hole DORC 87."

    On reading the report one might ask: are ALL the copper results AUM have reported "native copper".

    The following is an interesting read:

    "What is an ore?

    An ore is a rock that has enough metal in it to make it worth extracting the metal.

    The main ores of copper are:

    Chalcopyrite
    Bornite
    Malachite

    Over 50% of the World's copper comes from chalcopyrite and bornite.

    Native copper

    Copper is an unreactive metal - it reacts only slowly with the atmosphere. This means that huge lumps of copper metal are found buried in the ground as nuggets. This is called native copper. The largest nugget of native copper ever found came from Minnesota, USA and weighed over 400 tonnes. Native copper isn't mined because there is so little of it. Therefore it is of little commercial importance."
