Thanks, Bamako, for an understandable explanation. The simple picture is worth a thousand geo terms. Could you provide any insight into how big one the larger or main pumbing branch might be in feet or metres, and are you aware of any examples/ pictorials at any mining websites ? I've some background in a lot of things, nil in geo, and am trying to get a laymans understanding of what we think we might be looking for. Any Canadian examples with similar geology. All info/insight appreciated.
