Peter Cragg - Introduction to Treasure Talk

November 26, 2010 09:12am

Peter or as he is known on detecting forums as ‘Qld Sandy’ was first introduced to gold prospecting by a new neighbour in 1983. In that year he purchased his first VLF metal detector. His first gold find was a 0.1 gram piece and the sizes grew as his experience did. In those early years he spent as much time as possible detecting for nuggets and sometimes coins for a different challenge. He has through the years graduated to nearly every new Minelab SD, GP and GPX metal detector.

Because of Peter’s interest in detecting and his desires to assist others learn and become proficient in this hobby he recently opened ‘Gold City Detecting’ in April 2010...

Why Pulse Induction metal detectors work so well for gold detecting

November 22, 2010 11:51am

So as not to make this article enormous, if you see apparently strange new terms or acronyms, please consult our Terminology reference. (http://www.minelab.com/aus/consumer/knowledge-base/terminology)
By now, I would imagine that many metal detector operators have come up against the problem of mineralised ground when looking for gold. This is ground that produces noise from a conventional detector. Many gold fields around the world contain mineralised ground to varying degrees. In Australia, the gold fields contain exceptional levels of mineralisation.

Hot rocks - Part 1

November 18, 2010 02:57pm

Persons new to the hobby of metal detecting will probably realize fairly quickly that it isn't just the ground that can cause false signals. There are other things lurking in the goldfields that can be just as noisy; namely the dreaded hot rocks!

A hot rock can loosely be defined as: any rock or stone not containing a valuable mineral (gold, silver, or copper) which generates an audible signal response on a metal detector. The exact cause of this phenomenon has been debated among detectorists for some time.

Why do coins sink?

November 15, 2010 02:08pm

Several months ago while conducting a routine field test of a Minelab detector, I got a signal from just underneath a fallen log – I moved the log and found a coin target which as it turned out was on the surface hidden from view by just a few leaves – the date was 1946. A few feet away another signal produced a 1986 coin from around the six inch level.

At the time I didn’t think much about it as it was a routine test and many targets were located that day and that’s what I wanted, as many targets as possible to assess the detector.

Chris Gholson - Introduction to Treasure Talk

November 12, 2010 05:15pm

Chris Gholson’s introduction to gold prospecting started as a young boy when his grandfather began taking him along on his many excursions into the Arizona desert to search for Indian artifacts, relics, and of course gold.

In 1998, Chris wrote his first book, Metal Detecting for Placer Gold. In 2002, he authored another book about gold mining with his colleagues from the University of Arizona and California State University. He is a columnist for Lost Treasure Magazine, and is contributing author for several other magazines including: The Gold Prospector, and the International California Mining Journal.

The power of positive thought

November 08, 2010 02:11pm

Do you know your mind is a far more important part of a successful electronic prospecting equation than even the technology in your detector? Well it’s true, and for a very good reason! Without positive thought there is very little reason to get out of bed in the morning, becoming confident in what your detector can do by learning what it has to offer is a very big part of the equation which then leads you to becoming more confident in succeeding.

A lesson I learned very early on in my career was to always look at the glass as being half full rather than half empty, so in the field I will always leave something in reserve as a positive motivator. A good example of this is...
