During the month ofFebruary 1915, of the copper occurring in the form of sul-phides was recovered. The mill has been visited by mining men fromall parts of the world.

The mill receives 200 tonsper day of crude mine ore. After being crushed to 2-inch size, thisore is passed over a picking-belt, where one ton of high-grade ore andfour tons of waste are removed each day. The remaining 195 tons ofsecond-class ore is crushed in stamp-batterip«; t
