Metal-Mineral Identification Utilizing a Detector
November 2005 by Jim StraightSeldom is a metal detector used for ore sampling today. Nevertheless, this procedure still works as all BFO and VLF detectors have a non-conductive mineral zone and a conductive metal zone with a neutral null zone between them.
There were some exceptional times in the far-flung history of the West. Rich finds of minerals that set men’s souls ablaze. From the rich gold fields of California, men who arrived too late to find riches went searching in every direction. The trail that we will follow leads east, past the shining silver district of the Comstock Lode.
Lately I’ve been having success utilizing two types of detectors in succession. The first is a pulse induction (PI) detector with a blanket-style antennae, and I follow it up with a very low frequency (VLF) detector.
The idea of decisive action in 2014 will be at the heart of my presentation at the ICMJ Gold Prospecting and Mining Summit of April 5-6 in Placerville. I look forward to meeting you all then.

The Bureau of Land Management (BLM) has added some useful tools to their website. The Land and Mineral Use Records system has been meshed with a map viewer that allows users to obtain mining claim information in a useful format.
