ing the coming year
Mill and Flotation Plant.
While the property was shut down
extensive alterations and additions
were made to the mill and flotauon
plant, with the result that the milling
efficiency has been greatly increased
We are now shipping a zinc product
averaging from 80 to % per cent zinc;
the lead shipments are averaging 50
per cent with silver values averag-
ing over 20 ounces to the ton These
results have been brought about by
the changes in the mill, and the oper-
alton of the new sorting plant which
was built during the summer. This
sorting plant does away with all ore
sorting underground and the tram
ming of waste rock over the aerial
tramway from the mine to the mill
