State of the art of gold deposition and extraction knowledge in 1891 and 1893. Search "nitre" from edit/find in page blackmask.com This is a long but good read on what was known and guessed at in gold theory back then. More geologists today should read it as their courses in economic geology don't teach what these fellows knew then. I would venture to say Johnson was more right than wrong and many people are just finding out today what he thought was correct 111 years ago. Particularly interesting is his theory about cold exsolution of placer nuggets from carbonic acid streams in alluvial placers. Howard Lovell from Kirkland lake (OGS) thought it could be true and so did others. More work needs to be done here as vein formation theory lags in modern geological science. What did the prospector probably know and use? I would say close to all of it, if he had worked in the gold fields. Read down to "rules of thumb" and that is the practical guide. Harry Oakes was a doctor from Maine who had worked in the gold fields of Australia. When he found the Lakeshore Mine, he thought it would go down about a mile. Many geologists knew better. It did, however behave according to Harry's guess work. EC<:-}
