Doctor Vein/Ore-Shoot Description
The course of the Doctor vein is N. E. and S. W., dipping N. W. at surface 38 degrees, and with depth 60. The ore-shoots pitch with the dip of the vein to the N. W. In June, 1895, there was in this mine the best surface showing ever seen in Cripple Creek. Characteristic cubes of gold ⅛ by ½ inch were abundant through an uncovered area 12 inches wide by 15 feet long.

FIG. 3. PLAN OF SHOOT IN DOCTOR VEIN.

There are three well defined ore-shoots on this vein. None of them improve in value with depth; in fact the richest ores were mined within 60 feet of the surface.

In the North Star vein, with N. and S. course, dip W., the ore-shoot pitches north at 360 feet; the shoot yields from a 3-foot vein the best ore it has ever shown. A peculiar feature appears in the main shoot of the Doctor. Fig. 3 will give an idea of the S-like shape of the shoot. This figure S occurs on the hanging wall. Pay streak is richer on the hanging wall and only twice has it crossed from hanging to footwall.

In the Chief the course of vein is N. and S., dip vertical; pitch of ore-shoot, north. The ore occurs in association with two dykes in the breccia, one striking north and south the other north of west and south of east. The ore-shoot pitches to the north and south dyke.

At 210 feet, in the Doctor, the shaft encountered a nearly square chimney of mineralized rock 10 inches square, value $75.00 per ton ; continuing 16 feet, at 226 feet the chimney broke of abruptly. It had no connection with the vein and when first struck was supposed to be the apex of a new ore shoot.

1Info Title:
Doctor is Connected to Jack Pot
CONNECTION MADE.

In the tenth level of the Doctor mine a connection has been made into Jack Pot ground. The connection was made Sunday and now the air in both properties is good and clear. For the past ten days the air has been so foul that a large force of men were laid off, but with the connection just made the air supply in the future will be good.

When the connection was made doubt as to the conflict was set aside and it is proven that the Jack Pot is on the vein the Doctor is working.
