It is incredible having an engineer on the team. Cas Dobbin is able to look at the equipment within the mine and help us all understand how operations might have worked. This becomes mission critical when trying to find new targets for exploration. Tonight he described two theories about how the mine was dewatered from such incredible depths with 100 year old technology. He has also surmised how and where miners were able to tap into steam pipes to run their drills. This knowledge is helping us understand what we are looking at and envision where other infrastructure might be located. It makes it all that more interesting and gave us a refreshed vision of our unfolding map. My conclusion is that there are months if not years of work needed to explore and document this remarkable place.
