CHAPTER IV —MINES OF BEACON HILL. 
GENERAL INTRODUCTION. 
Beacon Hill, like Guyot Hill, is merely a prominent knob on the general south¬ 
west spur of Raven Hill. The principal geological feature of the hill is a vertical plug 
of phonolite, elliptical in plan, which is intrusive into the Pikes Peak granite and has 
been described on page 34. Tliis phonolite forms approximately the upper 150 feet 
of the hill, the lower slopes being granite. There are a number of prospects in the 
phonolite, but the productive mines are all in the granite. They lie in two belts 
parallel to the longer or northeast-southwest axis of the elliptical plug. One of 
these belts is on the northwest side of the hill and includes the El Paso, C. Iv. & N., 
Old Gold, Henry Adney, and other mines and prospects. The other is on the south¬ 
east side of the hill and embraces the Prince Albert, Gold Dollar, Zoe, Mabel M., 
Agnes, and St. Thomas mines. The general relation of the veins to the phonolite 
plug is shown in fig. 40 (p. 351). 
The Beacon Hill mines are noteworthy as lying at a greater distance from the 
main area of breccia than the other productive mines in the district. Their relation 
to the phonolite plug strongly suggests a genetic connection between this intrusion 
and the formation of the veins. 
EL PASO MINE. 
INTRODUCTION. 
The El Paso mine is situated on the northwest slope of Beacon Hill and is owned 
by the El Paso Consolidated Gold Mining Company. The original El Paso com¬ 
pany, organized in 1894, with a capital of $900,000, owned the Orizaba No. 1, 
Orizaba No. 2, Fannie B., Vulcan, and Bryan Fraction claims, covering about 
25 acres. Later the company was reorganized under its present title, with a capital 
of $2,500,000, and the Columbia No. 1, Columbus, Australia, Old Hickory, and 
Little May claims acquired. 
PRODUCTION. 
The gross production of the El Paso mine up to the end of the year 1903 was 
$1,698,576. The production for 1904 (with December conservatively estimated 
by the company) was $1,337,735, making a total of $3,036,311. The dividends 
paid in the same period amount to $506,250, besides which the company has added 
considerabh r to its holdings and has equipped' the mine in a very substantial 
manner. 
UNDERGROUND DEVELOPMENT. 
There are two important shafts on the El Paso property—the old El Paso 
shaft, near the east end of the Orizaba No. 1 claim, and the present main shaft, on 
the Columbia No. 1 claim, 600 feet north of the old shaft. The former is no longer
