for determining the original water level of the mine. The height to which the water 
rises when pumping is stopped has slowly decreased since the shaft was sunk to its 
present depth. 
GRANITE MINE. 
INTRODUCTION. 
The Granite mine, owned by the Granite Gold Mining Company, of Denver, 
capital $1,000,000, is situated on the northern edge of Victor, between the Portland 
and Monument mines on the east and the Ajax, Dead Pine, and Gold Coin mines on 
the west. The workings are embraced within the generally north-south Granite 
claim. The mine is operated under the leasing system. 
PRODUCTION. 
The Granite mine is credited with a gross production of 8400,000 prior to Janu¬ 
ary 1, 1900. We have been unable to secure any later statistics. 
UNDERGROUND DEVELOPMENT. 
The main shaft, 1,000 feet in depth, is situated on the eastern edge of the claim, 
250 feet from the northeast corner. The first level below the collar of the shaft is 
the so-called level 5, 445 feet below the surface. Level 6 is 150 feet below level 5. 
Then follow levels 7, 8, and 9, 100 feet apart, and finally level 10, 80 feet below 
level 9. The workings lie mainly south of the shaft, comprising on most levels a 
main north-south drift, reached by a westerly crosscut from the shaft, and various 
spur and parallel drifts with their connecting crosscuts. Level 6 is the most exten¬ 
sive, connecting on the west with the Dead Pine mine and on the east with the 
Portlaifd mine. A drift on this level also passes under the Monument shaft. About 
380 feet from the south end of the claim is the South shaft, about 200 feet deep, 
connecting with three short levels. These were not visited. 
LODE SYSTEMS. 
In the Granite, as in the Monument and Dillon mines, two prevalent systems 
of fissures are recognizable, one set striking nearly north, while the other set strikes 
nearly northwest. The most prominent of the nearly north-south fissure zones is 
the Granite lode, striking N. 8° E. This lode varies in dip on the different levels, 
but on the whole is nearly vertical. West of the Granite, at a distance near the 
middle of the claim of about 100 feet, is the West lode, striking in general due north 
and also approximately vertical. About 50 feet east of the Granite is the East 
lode, striking N. 5° E. This fissure zone has been drifted only on level 9, but, like 
the others, seems to be about vertical. On level 10 a fourth fissure zone, striking 
north, has been followed between the Granite and West lodes. 
The most prominent northwest fissure zone is the Bobtail—clearly the same 
lode as the Bobtail of the Portland mine. It dips about 60° SW. On level 5 the 
Bobtail crosses at the shaft. On level G it lies about 90 feet and on level 7 about 130 
feet southwest of the shaft. On levels 8, 9, and 10 the Bobtail is supposed by those
