All through this range the Ore sandstone is from 20′ to 25′ thick.
Nowhere do the Danville ore beds, though presenting in places a more or less profuse outcrop, seem to have been found sufficient good for development.
The Old Stackpole opening, whose ore was used at Glamorgan furnace, shows on the south side of the south anticlinal, a short distance west of McCord’s, where a drift has been ran through the overlying olive slates and the outcrop robbed for some distance east and west on a southeast dip of 30°. The ore breasts are very short here, and the ore itself is nearly all a lean hard fossil.
Some little development had been made on the property of Michael Aultz; and also at the John Allen property in a deep ravine about ½ mile further west. But the two ore-anticlinals have become so depressed in this vicinity that it was not possible to get good stoping ground, so that comparatively little ore was ever mined there.
At Peter Rush’s house, the ore ridge becomes almost imperceptible, the lower Salina red shales arching over the anticlinal and completely hiding the Ore Sandstone and Sand Vein ore-bed. From this point westward only the mountain outcrop is seen above water level, making a high terrace on the side of the mountain and a rather obscure ore outcrop.
The Stevenson mine, on the Cutman farm, is opened on this mountain dip of 70°, southeast, half way up the flank of the mountain and developed by a shaft a short distance east of Cutman’s house. This mine was formerly leased and operated by Rosenberry; but during the season of 1888 some perfunctory work was done there by Mr. W. P. Stevenson of McVeytown, and by Mrs. Cutman. The shaft was 105′ deep, sank 23′ vertically from the surface to the ore-bed and then following down the dip. It was not possible to get down the shaft at the time of visit, as the mine was not active; but the bed is said to be double here, 12 and 14 inches thick, separated by about 20 inches of white clay. The lower bench, however, is merely a ferruginous
