Mine Shaft


 Mine shaft to P30 on one side  P10 on other not descended due to lack of equipment.  
Bottom of the P30 leads to horizontal mine passage with 4 options:
1. Pitch with mine hoppers and rotten beams - not explored due to dangerous condition.  
2. Under the entrance pitch there is a tight rift that appears to connect with the a lower level.
3. Opposite side of bottom of the pitch the passage continues to a pitch that connects to another  pitch to the floor below. - Dangerous conditions so not descended.   
4. An enlarged mine passage leads to a natural passage that is too tight.  This could be enlarged but there is no apparent draft.
