| 1858 | Active again above adit as part of Llywernog United. |
| 1872 | Re-opened as Cardigan Old Bog with James Overton as manager, where new lode revealed good ore in a shaft 9fm deep sunk on it. |
| 1873 | 33ft x 3.5ft iron water wheel installed for pumping and drawing. This installed some distance from the mine. Company folded with equipment coming up for auction including ‘T bob balances, pullies, standards, 440 yards of iron rope and 25 fathoms of 6 inch pumps’. |
| 1882 | Lease secured by Craignant Bach company when lead prices were at their lowest point for 50 years. Pumping and drawing by endless iron ropes. Shaft fitted with skip road for ore raising. At 24 fathoms deep, the agent reported that the equipment would not stand another lift of pumps to go any deeper. The company gave up, and the mine closed. |
