Development - Lebanon tunnel 1,082 feet long; 2,500-foot tunnel on Edinburgh vein.
Production - $500,000 or more.
Veins - Network of branching and crossing lodes with general northeast trend. Most branches open to east. Alhambra: Strike, N. 55° E.; dip, 60° NW.; branch of Morning Star; intersections usually enriched, slickensides horizontal. Edinburgh: Parallel to Elija Hise vein. At junction with Scott vein, Edinburgh is a 6- to 8-inch quartz seam. Elija Hise: Strike, N. 75° W.; joins Alhambra. Everett: Strike, N. 65° E.; branch of Alhambra. Morning Star: Strike, N. 80° E., dip, 50°-65° NW.; eastern extension is East Peru lode; unites with Alhambra to west. Number 9: Extension of Peru. Peru: strike, west; dip, vertical. Scott: northeast extension of Alhambra.
Wall rock - Gneiss having northeast trend. Morning Star vein is partly on contact of Silver Plume granite and porphyry dike. Silver Plume granite along Scott vein.
Ore and sulfide minerals - Chiefiy galena, sphalerite, and tetrahedrite but some chalcopyrite and pyrite. Also iron oxides in Edinburgh vein and some barite in Peru vein.
Gangue minerals - Quartz.
Ore shoots - Rich shoots at junction of Alhambra with Morning Star vein; stoped 100 feet above tunnel level.
Tenor - At junction of Alhambra with Morning Star: 100 to 125 ounces of silver per ton, 26 percent of zinc, and 19 percent of lead. Sorted shipment contained 26 percent of lead, 14 percent of zine, 42 ounces of silver per ton, 0.1 ounce of gold per ton.
