Edward Shipsey, president; Thos. D. Nestor, secretary; Ray Drain, superintendent. Elevation 3900 feet.

The vein strikes northwest and southeast. Width 3 feet. Granite footwall and porphyry hanging wall.

Developments consist of shaft 520 feet deep, with levels every 50 feet. Present development work confined to the 300-foot level.

Equipment consists of 25-h.p. electric hoist and 5-stamp mill.

Ore mined from the 300-foot level is reported to assay $50 per ton, and during the month of April 100 tons were treated in the mill. Six men are employed.

A massive belt of limestone is exposed on the ridge northeast of Cuddy Canyon, the general strike being northwest and southeast, with a dip to the northeast. The limestone is exposed for a distance of 4500 feet in length and about 300 feet in width. The material is white and crystalline. Analysis reported as 96% CaCo,. Idle.

EAGLE MOUNTAIN DISTRICT.

Iron Chief Mine (gold). Situated in the northern part of Eagle Mountains, forty miles northeast of Mecca, a station on the Southern

Pacific Railroad. Elevation 2500 feet. Owner, Southern Pacific Railroad Company. Holdings comprise six patented claims known as the Gray Eagle Group.

The property was originally located by William Stevens and Thomas Dolfflemeyer of San Bernardino. In 1897 the mine was sold to Mr. Charles Lane of San Francisco, who installed a small mill on the property and operated it for several years. The ore milled is said to have had a value of $40 per ton, of which about 50 per cent was recovered. It is stated that the production was $50,000. Mr. Lane did not complete payments on the property and the original owners then installed a 50-ton cyanide plant, operating the mine and mill until about 1902, when sulphide ore was encountered and operations were suspended. The ore milled is said to have had an average value of $10 gold per ton. The production is reported to have been $150,000.

The ore is largely hematite which carries free gold. It occurs as a

replacement along the contact of dolomite and quartz-monzonite. This contact strikes N. 70° W., dipping 50° N.

Developments: Consist of vertical shaft 140 feet deep. About 500 feet west of the shaft a tunnel has been driven east 1000 feet along the contact, cutting the vertical shaft at a depth of 100 feet. On the north slope of the hill, a crosscut tunnel has been driven south 500 feet to the contact. The ore cut in these lower workings was heavy pyrite ore, with some chalcopyrite. Only the oxidized ore above this level was worked. The ore along the contact fissure had a width of from 2 to 10 feet.

Mine equipment: 25-h.p. Foos gas engine.

Mill equipment: Two Blake crushers, Gates rolls, eight 4' x 18' steel cyanide tanks.

Water was secured from Cottonwood Springs, situated eighteen miles south of the mine. Idle.

Black Eagle Mine (lead, silver, copper, gold). Situated in the northern part of the Eagle Mountains, forty-seven miles northeast of Mecca, a station on the Southern Pacific Railroad.

Elevation 2100 feet.

Cottonwood Springs, Eagle Mountains, Riverside County.

Owner, Edward Harmon of San Bernardino, California. Under option to A. W. Scott and George Hayden of Los Angeles. The property comprises three unpatented claims known as Maleta No. 1, No. 2, and No. 3. Area 60 acres.

Riverside County.

The Black Eagle vein courses through the center of Maleta No. 1 and No. 2 claims, its strike being N. 70° W., with a dip of 85° to the north. At approximately the middle of Maleta No. 2, the vein inter

sects a cross vein which has been formed along a fault fracture. The intersection of these two veins show a mineralized fracture at least 15 feet in width. The Black Eagle vein occurs along the contact of quartzite and diorite, forming a contact fissure. Several hundred feet north of the diorite and running parallel to it are strata of dolomitic

limestone, which in many places are replaced by iron oxide, mainly hematite.

Development: The present development is on Maleta No. 1. On this claim an adit tunnel has been driven N. 70° W. for a length of 255 feet. At a distance of 162 feet, a winze has been sunk to a depth of

100 feet. From the bottom of the winze, drifts have been run 40 feet east and 100 feet west. The adit tunnel was driven along the hanging wall of the vein for a distance of 196 feet, where it cut into the vein at what is known as Stope No. 3, and then continued along the vein to the face of the tunnel. The orebody, as exposed by these workings,

is 150 feet long, with an average width of 4 feet, and is stated to have an average value of $21 per ton in gold, silver, lead, and copper. The vein varies from 3 to 9 feet in width. The ore occurs in lenticular form in the vein. The vein filling is quartz, mineralized with galena, malachite, azurite, cuprite, anglesite, cerrusite, cupro-plumbite, and lead vanadate.
