A giant sinkhole has opened up, near a Lundin Mining Corp. Copper mine in Chile, forcing the Canadian miner to suspend, some development work at the site.<br /><br />Chilean authorities are investigating the cause, and Toronto-based Lundin has suspended development work, at the Alcaparrosa mine in the northern part of the country.<br /><br />Chile’s geology and mining regulator, Sernageomin, posted a picture of the 25 meter-wide sinkhole, on Twitter on Monday. Sernageomin is analyzing the sinkhole, and will issue recommendations in due course.<br /><br />Alcaparrosa is part of Lundin’s Candelaria copper gold and silver complex, which is 80 per cent owned by Lundin, and 20 per cent by Japan’s Sumitomo Metal Mining Corporation Limited.<br />
