Ophir—Possibly the Best Kept Secret in Alaska!
November 2013 by Chuck Merritt...I decided to excavate the semi-frozen high-bank that was resting on a soft shale bedrock footing. Within three feet, I encountered an intrusive!
Depth is not an issue unless the site is thoroughly cleaned of shallow trash, and it is far easier to isolate and remove targets using a small coil in a target rich location.
I am going to break bedrock down a bit and explain my view of the varying scenarios I come across in the field.
Some creeks have nuggets, while others, particulary the rivers, nothing but fine gold.
This article is intended to try to help someone who is breaking into gold detecting and using a pulse induction (PI) detector.
I believe dry washing is an underappreciated prospecting method. There are plenty of places where there is some pretty decent gold to be had, but the spot is a long way from any water and dry processing may well be the best way to go.
Easing around the bedrock ledges and rock hopping, Terry and I came out into the open and were looking at a nice run of bedrock.
