This property, owned by the Isabella Mines Company, consists of about sixteen claims forming an irregular area of 160 acres on the northern slope between Bull Cliff and Bull Hill. It was one of the most productive mines of the camp from 1895 to 1900. In 1899 the output reached the maximum, $968,000. The total sum is between $3,000,000 and $4,000,000, and dividends have been paid to the amount of $675,000. For the last few years the mine has been worked in a small way by lessees.

The mine is opened by the vertical Lee shaft, from which fourteen levels are turned. The elevation of the collar is 10,460 feet, and of the sump 9,332 feet. The first eight levels average 70 feet apart, while from 8 to 14 the distance between them is 100 feet. Level 3 is 202 feet below the collar; level 7, 438 feet; level 8, 520 feet; level 10, 720 feet; level 14, 1,120 feet. The Buena Vista incline. is sunk on the vein 800 feet north-northwest of the Lee shaft, and follows it down to level 7. Level 3 corresponds with Victor level 5, and level 11 with Empire State level 11. There are several miles of drifts and crosscuts: chiefly on the Buena Vista and Cheyenne veins, which have been opened for a horizontal distance of 3,400 feet.
