CHAPTER VIII. 
-MINES OF BATTLE MOUNTAIN (WEST GROUP) AND 
OUTLYING PROSPECTS. 
STRONG MINE. 
INTRODUCTION. 
The Strong mine, situated on the southern slope of Battle Mountain, near the 
northern limits of the town of Victor, is owned by the Strong Gold Mining Com¬ 
pany, of Colorado Springs, incorporated in 1892 with a capital of $500,000. It lies 
between Stratton’s Independence mine on the east and the Dillon mine on the west. 
On the north it joins the Portland property. The Strong workings were originally 
confined to the Strong claim, running about N. 6° W. By compromise with the 
Portland company, however, 250 feet from the north end of the Strong claim were 
exchanged for a triangular area extending southward from the Portland property 
between the Strong claim and the Maggie claim of Stratton’s Independence mine 
and tapering to a point about 600 feet south of the northeast corner of the original 
Strong claim. 
PRODUCTION. 
Statistics of the gross production of the Strong mine are not obtainable, but 
for a comparatively small mine it has been a remarkably regular and profitable 
producer. The dividends paid are as follows: 
1892-189G 
1897 . 
1898 . 
1899 . 
190C.

UNDERGROUND DEVELOPMENT. 
Access to the Strong workings is through the vertical Strong shaft, 904 feet in 
depth and situated about 340 feet from the south end of the claim. There are 
nine levels, approximately 100 feet apart. These are of generally linear plan and 
run nearly north and south. The principal development has been north of the 
shaft. The northern portions of levels 2, 3, 4, and 5 were not accessible at the 
time of visit, being partly caved in and partly bulkheaded. 
LODE SYSTEMS. 
There is but one important lode in the Strong mine—a nearly north-south zone 
of sheeting, which usually dips to the east at angles ranging from 80° to 90°. The 
general dip is about 84°. As will presently be shown, this lode is closely related to 
two nearly north-south dikes, one of phonolite and one of basalt.
