March 2016 by Chris RalphCan a metal detector be used to find limonitic gossan material?
Every time we prospected here we found gold, sometimes some really coarse flakes, but no large nuggets (yet).
You keep all you find at Ganes, with weekly tallies kept for a loose competition that I find helps motivate me. I seriously try to find more nuggets than anyone else in a given week, and usually make it or close to it.
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.

Looking for nugget laden bedrock in forested mountain regions, you first need to explore the banks of the gold-bearing streams and look for the bedrock that is exposed as this is your starting point.
Last month, in “Following Clues to a Hidden Gold Deposit,” I ended the article with the direction that we were on the hunt! We were getting prepared and ready to roll with our detectors, then snow came, and lots of it. We had already found the seam diggings mine on the mountainside in wild, rough brush and trees. It had been well hidden.
I love to dry wash old nugget patches found by detector operators, and I have found my fair share of gold dry washing those areas. I have also found a few nuggets using a detector on the bedrock exposed by dry washing the patches.
