Arian Silver has uncovered the widest intersections of economic grade silver mineralisation so far at its 100%-owned San Jose Property in Zacatecas State, Mexico.The results from the first two holes in the Guanajuatillo area along the San Jose Vein comes as the group completes 24 holes of its phase 3 drilling campaign, about half the planned total."We are highly encouraged by the latest results from our current phase of drilling along the SJV," chief executive Jim Williams said. Proceeds from the 68 tonnes of concentrate sold to date are about $580,000.Central Asia Metals has agreed to sell its Tochtar subsidiary to Wildorf Holding Limited for US$2.5m made up of $825,000 in cash and $1.675m of historical cost liabilities. The company decided to stop mining at Tochtar, which is in Kazakhstan, in 2009.Australia-focused miner Thor Mining said samples from its Daicos prospect near Harts Range in the Northern Territory have not given any indication of economically significant mineralisation at the prospect. Assays from further reconnaissance surface sampling at the Dundas gold project in Western Australia have identified additional anomalies for follow up and potentially drill testing, the company said.
