Prospecting & Detecting
Proper Assaying of Placer Samples
November 2012 by Jim Halloran
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.Chasing Float Gold—The Starry Night Wash
The sun was beginning to set, which put the light at just the right angle against the hillsides to where I believed that I spotted a very small dig and tailings pile up the hill near the top of the second wash.

I suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
A Father and Son Prospecting Adventure
As I write this, I am still on a rush from taking my 9-year-old son, Jeffrey, prospecting for the first time this past weekend. It’s not that he hasn’t been along on numerous outings before: this is the first time that just the two of us went out for a day of drywashing and detecting under the desert sun.
That First Nugget
After getting all the gear together we headed up the old road that led us to an old ground sluice site. George and Kaleb were using lightweight VLF (very low frequency) detectors. I carried a newer technology unit that is just a tad coil-heavy in the front.
Cold Alaskan Gold—Part I
Crowds may be great for football games or the Fourth of July, but not for prospecting. So, this summer, while thousands of gold seekers were heading to the coast of Alaska, I headed to a remote part of the Interior.
