The Doctor-Jackpot and Morning Glory group includes a number of mines which were formerly worked under individual ownership, but which are now controlled by three companies. The Doctor-Jackpot Company owns the Ingham, Mattie D., Jack G., Doctor, Elizabeth Cooper, Jackpot, and other claims, which were consolidated November 30, 1901. The Work Mining and Milling Company owns the Morning Glory, Morning Glory No. 2, Morning Glory No.4, Ida B., and Little Clara claims.

The Morning Glory, Doctor, Ingham, and Mattie D. mines began to ship ore in 1893, and the Elizabeth Cooper and Jack G. in 1895. In August, 1895, rich ore was found in the Doctor, and during the month of September, 1896, this mine was reported as shipping 600 tons of 10-ounce ore. In 1898 the Jackpot began to ship, and in the following year paid dividends amounting to $150,000. In 1900 the Doctor and Jackpot companies became involved in a legal contest for possession of the great ore shoot, which was settled by the consolidation, as previously stated, of the two companies in November, 1901. The Doctor-Jackpot mine continued to ship ore during 1902, but the company was much hampered in its operations by water. In 1903 the main pay shoot had been nearly worked out down to the water level and the company suspended operations. The mine is at present operated by lessees.

The workings of this group of mines are extensive, the numerous drifts and crosscuts penetrating a large portion of the western half of Raven Hill. The area exploited has a length from west to east of about 2,800 feet, and from north to south of about 1,800 feet. The principal access to the workings at present is the vertical Morning Glory shaft, near the "Low Line" station of the same name. This shaft is a little over 700 feet in depth and has three levels situated 100, 550, and 700 feet below the collar. Of these the 550-foot level is most extensive. The mouth of the Doctor inclined shaft is 950 feet east of the Morning Glory shaft and about 200 feet higher up the slope of Raven Hill. It follows the northwest dip of the Doctor-Jackpot lode down to a point about 40 feet above the 700-foot level of the Morning Glory shaft. The Doctor levels are about 50 feet apart vertically, the 700-foot Morning Glory level corresponding to level 17 of the Doctor, and the 550-foot Morning Glory level to level 14 of the Doctor. The general angle or dip of the incline is 55°. The Doctor shaft house was destroyed by fire a year or two ago, and the incline is no longer used. None of the levels above 10 were accessible at the time of visit. On the Jackpot claim are two shafts, one vertical and one inclined. The vertical shaft, 300 feet southeast of the Morning Glory shaft, connects with the 550-foot Morning Glory level and is still in use. A small shaft on the Elizabeth Cooper claim is also in use by lessees. Scattered over the property are a number of other shafts, such as the Ingham and Chief, on the Ingham lode, which are no longer in use. There are also two adits, formerly of more importance than now. These are the Doctor tunnel, with its portal near the collar of the Doctor incline; the Orehouse tunnel, which is level 1 of the Doctor shaft, and the Mattie D. tunnel, about 500 feet east-southeast of the Doctor incline. The Mattie D. tunnel follows the Mattie D. lode, which has been worked also through an inclined winze to a depth of nearly 300 feet below the adit level.
