and also the Conundrum claim, which is elsewhere described. The mine has been 
worked principally by lessees and made its first shipment in 1895. It continued 
productive until the latter part of 1899; since then but little ore has been shipped. 
The Jefferson mine lies just north of the Anchoria-Leland, with workings confined 
to the Mattie L. claims. It is owned by the Jefferson Mining Company, of Denver, 
incorporated in 1892, with a capital of $1,100,000. The Geneva mine is northeast 
of the Jefferson and belongs to the Stratton estate, having been purchased in 1900, 
with the May Queen claim, for $300,000. Neither the Jefferson nor the Geneva 
mine is at present actively worked. The Half Moon mine is situated south of the 
Geneva and east of the Anchoria-Leland. It is owned by the Matoa Gold Mining 
Company, of Colorado Springs, incorporated in 1892, with a capital of $1,000,000. 
The company owns the Half Moon, Harlan H., and Gold Pass No. 1 claims, with 
other property in Arequa Gulch. Ore was discovered in the Half Moon in 1893 at a 
depth of 250 feet, and shipments were made at intervals for about five years. 
PRODUCTION AND DIVIDENDS. 
The Anchoria-Leland is credited with a gross production of over $1,000,000, 
and has paid $198,000 in dividends. The first dividend, $6,000, was declared in 
1896 and the last, $18,000, in 1899. The gross production of the Jefferson is not 
accurately known, but is probably between $300,000 and $400,000. The Geneva 
shipped considerable ore in 1895, 1896, and 1897, but the gross production has not 
been ascertained. The Half Moon mine has produced between $600,000 and 
$700,000, chiefly through lessees. One dividend, $25,000, was declared in December, 
1898. 
UNDERGROUND DEVELOPMENT. 
The principal workings of this group of mines are on the Anchoria-Leland 
property. The Anchoria-Leland shaft is 1,100 feet deep, the collar being 10,139.46 
feet above sea level. The first main level is 277 feet below the collar. Level 2 is 
65 feet below level 1; level 4 is 153 feet below level 2; the Cripple Creek and Gold 
Hill tunnel is 270 feet below level 4; the Good Will tunnel, or level 6, is 32 feet 
lower; and level 8 is 142 feet below the Good Will tunnel. Levels 9, 10, and 11 
follow at intervals of 96 feet. The levels of chief importance from their extent, 
productiveness, or geological interest are 1, 2, 4, and the two adit levels. The 
principal drifts are on the Chance lode and run nearly north-northeast and south 
and southwest. (See fig. 25.) The Jefferson and Geneva drifts are on the same 
line of Assuring. About 300 feet southeast of the Chance drifts is a series of drifts 
with nearly the same trend, on the Matoa and Potter lodes. Northwest of the 
Anchoria-Leland shaft there has been some irregular and disconnected drifting 
along the City View lode, which is associated with a basaltic dike. These drifts 
are mostly from 200 to 250 feet northwest of the Chance drifts and approximately 
parallel to the latter. There is a fourth series of drifts running north-northwest 
and south-southeast on the Mahoney lode. The Jefferson incline, 450 feet north¬ 
east of the Anchoria-Leland shaft, is about 650 feet deep and has eight short levels.
