RE: Sooty black stuff " tetrahedrite"i am not sure if it was bunker hill or sunshine, bit one of the mines had a banner year , pulling out 12 million ounces of silver in the year , with an average of 40 ounces per tonne. I would be happy with those numbers, but 19 % sounds allot better. There is silver all around them it would be hard for them to drill and not hit any silver. I sure they feel they have hit the motherload, as lond as Russel get Plus 25% grades he will be extremly happy. It will be interesting to see what Morgan has to say about this
