| 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. |
| Company geologists regularly visit stopes and development headings to gather samples, map local geology, and give direction to miners. |
| This meant we had to carry heavy battery-powered lights into the old stopes. |
| Several pockets up to 1.3 meters and containing calcite crystals were exposed in the walls of the stopes. |
| By this time the mine had three shafts, many large stopes and hundreds of metres of drives. |
