Location and Description

The Godiva Mine lies on the north eastern slopes of Godiva Mountain, and is opened by a shaft and tunnel. The collar of the shaft is at an elevation of 7,025 feet, and is 900 feet deep with 9 levels (probably turned every 100 feet). The Godiva Mine also connects with the nearby Tetro Mine via a connection on the 500 foot level. The connection consists of a 1,300 foot long tunnel that ascends 200 feet towards the Tetro Mine, where there is a 500 foot vertical shaft that ascends to the main Tetro tunnel.

Workings and Ore

The ore was largely oxidized, and mainly consisted of cerussite, anglesite, and galena, with small amounts of silver averaging 9 ounces a ton. The ore bodies follow northerly trending fractures in the Limestone, with several offsets along local cross fractures. On the 100 foot level there are stopes that extend nearly continuously for 300 feet north and 500 feet south of the shaft, trending a few degrees northeast-southwest, with a width of 30-40 feet. The ore bodies found on the 200, 400, and 500 foot levels are smaller than on the 100 foot level. On the 200 and 400 foot levels, irregular ore bodies were discovered 100 and 400 feet west of the shaft, respectively.

Geology

There is a rhyolite-limestone contact very close to the collar of the Godiva shaft. All of the lower slopes of Godiva mountain are covered by rhyolite. On the 200, 500, and 600 foot levels, the same rhyolite-limestone contact is exposed. The rest of the workings in the mine are in the Pine Canyon limestone, with principle fractures striking North 30° west, wheras the limestone has a strike of north 15° west. On the Godiva tunnel level, which is the 200 foot level of the shaft, the contact with the rhyolite is sharp, vertical, and somewhat overhanging. The rhyolite is clayey, with a lot of fine grained pyrite and gypsum. The contact also adjoins a mass of limestone detritus, with its coarse fragments being distinctly oxidized. Very little mineralization occurred in the contact, but 25 feet away, in a limestone fracture, small amounts of ore were discovered. On the 600 foot level, a pipe of fragmental rhyolite appeared in the limestone. On this same level, the contact is thought to be exposed, but very little rhyolite was actually found.
