Prospecting & Detecting
Sampling Placer Stockpiles
August 2013 by Jim Halloran
Sampling other people's stockpiles or dumps has some inherent risks that sampling undisturbed ground does not have.
Gold From Black Sand Tailings
The pile up on the small hill had to be a couple yards of black sand. I’m not one to ignore a little gold even if it is small in size—I have always believed that gold fever comes in all sizes.
Diamond Prospecting in Indiana
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.
Colorado to California for Gold
The total after a great day added with the previous days put them up to 9.07 pennyweight—just under a one-half ounce of beautiful California gold.

Clues for Detecting Ancient River Channels and Flats
The gold in this area can get quite large. Most of the pieces are about half a pennyweight on average.
