August 2013 by Chris RalphQ: Will my detector react to fine gold?
Once a seam is found it can be traced for miles in either direction. While you are tracing a clay line, you are looking for indicators. The indicators that I look for are ironstone, hematite, different color clays intermingled with the clay line, and a very iron-rich, brown gritty soil.
The old timers typically washed these areas down to bedrock, and some areas appear terraced. I would imagine this is because these hydraulic mines were generally where the miners found old Tertiary river channels on the sides of mountains that were gold-bearing.
These gritty clay lines were only a quarter of an inch up to three inches wide. Once the line had been laid out, they would look at the wall of gritty clay material and seek more indicators.
A number of visiting gold miners were quite impressed with our operation and the amount of gold we had recovered in only three hours. No one usually likes digging and slugging buckets all day long, but we actually began to enjoy it after a few good...
Historically, Montana has been an important gold producer, in terms of both lodes and placers, and it still produces gold for the prospector today.
My first personal experience with placer diamonds was on a gold prospecting trip in Indiana about 8 years ago, when a fellow prospector was cleaning his gold concentrates.
