Summit Mine

The Summit mine is just west of Melendreth Pass, on the trail descending Sawmill Canyon, at an elevation of 5,700 feet. It is opened by an incline of unknown depth sunk on a quartz vein 1 to 2 feet wide that dips 75° W. The ore as seen on the dump contains galena, tetrahedrite (gray copper), malachite, and azurite rather widely disseminated through the quartz gangue. The sulphides begin at the surface².
