and between it and the Sand rock there is a bed of good porous light ore, 4″ to 6″ thick. The same bed occurs at Keever’s & Phillip’s banks.
North flank of Shade mountain.
On the south side of the Lewistown valley, along the north flank of the Shade mountain and Blue Ridge, the ore developments are very meager, owing both to the steep dip of the Ore sandstone which carries the outcrop of the fossil-ore bed high up the mountain flank, and to the uncertain quality and thickness of the ore. Through this part of the field the Ore sandstone and Iron sandstone pass into the high terrace of the mountain, and no longer form separate ridges as in Union and Snyder counties.
East Shade mountain ore
On East Shade mountain, south of Painterville, the Ore sandstone is about 25″ thick and dips 50° to 60° N. W. The Sand Vein was found here 12″ thick in an old tunnel, but hard fossil and lean. The Ore sandstone is about the same thickness south of Wagner Station at Oswell’s Gap, and in an old shaft here the “Sand Vein” is found 10″ to 12″ thick, yielding the following analysis:
| Iron, | 42.700 | per cent. |
| Sulphur, | trace. | |
| Phosphorus, | .138 | |
| Insoluble residue, | 28.080 |
The Sand Rock, beneath the Ore sandstone, is a coarse, sandy ferruginous rock, from 2′ to 3′ thick, and the Danville beds, though not opened, show a considerable quantity of soft fossil-ore at the outcrop. At Mowry’s Gap, next west, and about 10 miles east of Lewistown, both the Sand Vein and Danville beds show outcrops of good soft fossil ore.
South of Maitland Station, the Sand Vein is said to have have once been opened in a shaft sunk by William How, and showed a soft fossil 16″ to 18″ thick. The dip here has flattened to 40° N. W. The Ore sandstone continues to make a high terrace ridge from here as far as Jack’s creek and
