The mine is larger than expected for the reported production. The source map indicates that the recovery rate was very low; rooms extend only one-third the distance to the outline shown on the map. The mine may have had previous operators (see the unlocated mines), but the most likely factor in the size discrepancy is most likely the over-generous mine outline. Large blocks of unmined coal probably exist within the large outline (few rooms are shown on the source map).

Geological Problems Reported
One room has a cave-in labeled on the source map. The legend on the source map says the mine was closed due to flooding and falls. The flooding must have been fairly serious, because the legend also states they lost all machines and steel and copper contents of the mine. Both slopes were very near the stream.

Notes
- ↑ This slope may have been an airway only. The air course is labeled and ventilation arrows are drawn showing it to be an intake airway.
- ↑ The source map is dated 12-28-1961, and the next line states “closed June 27, 1963". No production was listed in the Coal Reports between 1959 and 1963.
- ↑ The photocopy is of the same map shown on the microfilm document 352203, reel 03138, frame 256.
