|Small irregular opening with small mine dump.|
|Larger mine dump: Let's go see what's there!|
|It's a small shaft with old timber as shoring. The round-headed wire nails suggest that this is a relatively recent shaft: probably post-1910.|
This particular hole was unbarricaded.
You always have to ask this question: What were the oldtimers digging on? A few, narrow, high-angle fractures or structures can be seen above the first irregular opening or adit. Iron-staining and possible veining (silica? calcite?) can be seen in the rock at the shaft. Did they mine anything? Hard to say without doing a little more research into the area or more work in the field.
