prices for copper and silver are moderately high. In Howson basin
mineralization has taken place along fracture zones in volcanics,
or along the walls and in granitic dykes. The minerals are mainly
copper with low silver and traces of gold. Most deposits (Duchess,
Evening, Silver Heels) are irregularly and sparsely mineralized,
although in some places as much as 5 per cent of the veins contain
minerals. On the Santa Meria a well-defined replacement vein
along the bedding has been traced for 450 feet with a width of

5 feet, in which there are irregular bands and streaks of massive
sulphides, but these are not continuous in the vein. The massive
sulphides are usually less than a foot of the total, but in places
range up to the full width of the vein. At a depth of 120 feet no
ore was found in the northern part of the vein. The ore is largely
chalcocite, which is secondary, and bornite, which may be in part
primary. From mining operations on one small section of the vein
239 tons were Gel secear noses hand sorting and shipped to give returns
of 17 per cent copper and 9.05 ounces of silver to the ton. The
primary minerals are believed to be chiefly chalcopyrite and
pyrite. The vein has a marked iron cap. This deposit is of
special interest because of the apparent secondary enrichment.
This appears to be limited Ponieae than 120 feet in the workings
and in places probably is not present since elsewhere primary
minerals occur at the surface.

Two groups, the Duchess and Contention, were optioned
and worked in 1928 and 1929 by the Consolidated Mining and
Smelting Company, but were cropped.
