MINES OF GOLD HILL. 
293 
The property is dotted with small shafts, most of which were sunk by lessees in 
the early period of the mine's history, when each lessee sunk a shaft on his particular 
section of a lode. 
GEOLOGICAL FEATURES. 
The general country rock of the Anchoria-Leland mine is the usual breccia of 
Gold Hill. This is cut by a few unimportant dikes of phonolite and by the City 
View basic dike. This dike is exposed in the Good Will and Cripple Creek and 
Fig. 25.—Plan of level 1 of Anchoria-Leland mine and of adjacent levels of the Jefferson, Geneva, and Half Moon mines, 
showing principal lodes. 
Gold Hill tunnels, in the old Progress workings on the Gold King claim, in the City 
View workings, and on several of the main Anchoria-Leland levels. On the north¬ 
east it approaches the Chance lode and the two apparently come together near the 
Geneva shaft. The Geneva workings, however, were not visited. Like other 
basic dikes in the district, the City View dike frequently branches and pinches. In 
the Good Will tunnel at least four narrow “basalt” dikes are exposed in a zone 
about 300 feet wide. All may be branches of the City View dike. The dike is 
usually less than 2 feet in width.
