ore varies from 18″ to 2′ in thickness with some “Jack” near the bottom and dipping S. 15° E. 40°. One drift had been carried through the Ore sandstone about 20′ thick, in search of the Danville beds, but they were found to be worthless, spread through about 2′ of calcareous slates.
R. Nankewell has again opened the Sand Vein about three-fourths of a mile west of Aughey’s; but no mining had been carried on there since June, 1887, when the last shipments were made to the Logan I. & S. Company. It was claimed that the ore improved in quality considerably coming westward from Aughey’s, but there was no evi- dence of the truth of this statement in the appearance of the ore itself. Both localities should furnish an ore containing from 40 to 42 percent. of metallic iron and from 18 to 25 per cent. of siliceous matter. One drift at Nankewell’s was carried in northwards from the road at his house for a distance of about 10 yards, and a gangway carried west- ward from there on the ore bed for 250 yards additional. A second opening further west is carried into the bed upon a slight northwest pitch in order to avoid the excessive length of a drift which would have been necessitated by the gentle slope of the terrace. Mr. Nankewell reports the bed as dipping 45° S. E. and with the following average section:
| Roof, clay slate. | ||
| Ore breaking in square blocks, | 12″–14″ | 2′± |
| “Jack,” | 7″–10″ | |
| Ore, soft and good | 2″ | |
| Foot wall, sand rock. |
Several thousand tons of ore have been mined and shipped from this point, the last mining being conducted entirely upon the upper thick bench. The bed is a mixture of soft and hard ore, the soft variety rarely extending much below 30′ from the outcrop.
The Geiss mines are located between these two properties under similar circumstances, where, however, all the soft ore has been worked out and the mines abandoned.
The outcrop of the Ore sandstone and fossil ore can be traced with more or less success for 5 miles west of Nanke-
