Happy Birthday, ICMJ!
September 2020 by Scott Harn
You’ll note the text on the cover now says “Celebrating Our 90th Year.” Yes, we are in our 90th year of publication!
A lot has changed since our gold and black cardstock cover bearing the title California Mining Journal. Through the years, we’ve tried to balance our content to include all levels of experience, from first-time prospectors up to small operations. We’ve sought to provide consistent, quality articles in every issue, and we very much appreciate the feedback and compliments from you, our readers. It’s also been a challenge to adapt to the younger, Internet-based generation, but we now have over 20 years’ worth of articles online along with downloadable 3D issues for the past six years at www.icmj.com. We also have Facebook, Twitter and Instagram accounts. Yes, we are hip 90 year olds!
But we’ve noted that the majority of our readers still prefer to carry a print copy with them around the house or out at their mining site, though there is an increasing crowd of paperless online-only readers too.
To all our readers, we are grateful and we look forward to reaching 100 with your continued support.

The Pay Streak: Redefined With Metal Detectors
The time-honored objective in recovering gold from placers has always been to discover and recover gold from the detritus of both known and unknown lodes. The traditional method to recover gold from desert dry placers was to locate and work the enriched gravels known as the “pay streak.” This pay streak was usually found directly over false or true bedrock and within the upper few inches of the bedrock itself.
Why Did This Silver Mine Close? - Pt III
Narrowing down a closure date will allow you to check the commodity price during that time and possibly confirm that a low price, rather than a lack of ore, was the driving force that closed the operation.
