For the next ten years it was leased to tributors who worked the old stopes of the conglomerate lode above the adit level. |
Open stopes extending upward to grass roots are not uncommon in the area, and hikers and tourists should take note of this danger. |
The remnant ore inside the old stopes, pillars and tailings used as backfilling are being leached with mild acid solution. |
We explored the areas that were not being mined, including miles of old abandoned drifts and stopes. |
Company geologists regularly visit stopes and development headings to gather samples, map local geology, and give direction to miners. |
Dunham noted that fluorite was more common in stopes developed on veins lower down in the Melmerby Scar Limestone than in the upper flats. |
