There has been some problems finding this one. Updated coordinates and giving instructions. There is somewhat of a trail along the foundation on the uphill side. Follow the trail, cache is between trail and foundation.
In 1859 The Hancock Mining Co incorporated and by 1860 had 2 shafts (the #1 located under the dorm at Finladia, and the Dupuis, located in a small building just down White St), 2 addits and a stampmill on Portage Lake (downhill of the #1). The money was poorly spent and the mine closed to tribute in 1866. Re-opened in 1873 as the Sumner Mining Co, but closed within the year. Re-opened again in 1880, but problems soon began. Iron began to be found with the copper, and when smelted, the copper output wasn't pure. The stampmill tailings also started to clog the waterway and the mine closed again in 1885. In 1906 re-opened as the Hancock Consolidated Mining Co. The #1 was re-opened (was at 1052') and the #2 was started. A massive 30' by 10' vertical shaft, it reached 1300' by Nov 1908. The mine closed in 1920 at a depth of 4100'.
The ruins of the rock house can be found across the street. The property along Elevation St is private, but the ruins are on city property and can be accessed off 2nd St. The large concrete slab with the pipe in it is the cap over the shaft.
Cache is by the Engine House. The east side housed two air compressors. On the west was a smaller hoist that was used from 1906 to 1911. A larger hoist took over as the mine deepened (hoist was to the east, now mostly burried in rock when the aparment building uphill was built). 17.5 million lbs of copper was recoverred.
