Entry is free and there will be evening meal also. More details to follow...
To do an accurate positioning on the surface :hmmm...... we have survey data that puts Astronomer's passage nearby but closer to the river. We are hoping if no actual inlet cave there to use the shale band that we should soon encounter to dig towards Astronomer's shaft. 'Proven right' we shall see!
We have used a Distox survey on the surface and so far surveyed most of Astronomers passage need to add new bit on and future finds, Shows passage near shaft to be 8m away horizontally and 12m depthTo do an accurate positioning on the surface :
- Arva measuring from inside and outside ==> this will give you an idea where to dig. But not 100%
- Arcana measurement from inside and outside ==> 100%
Sorry for late reply been away......yes you are right same mineralisation and possible connectionWhere the figure B is on the survey of the initial post, is a silt choked rift heading straight to the Dry Wath /Frog Pot connection. Presumably that's the mineralised area you spoke of in the past, same mineralisation in the rift walls on the Hardy Pools side.
