Natural Gold
This spectacular gold nugget weighs 5.17 ounces and was recovered in late April of 2007 in Mariposa County, California. The gentleman who found it was using a metal detector to look for gold nuggets. It was covered by about one foot of soil. The finder valued the piece at approximately $10,000 because of its beautiful specimen quality. Only a few weeks before another large nugget, weighing in at over three ounces, was recovered about 50 feet away.
Montana Bob Dansie assembled this fantastic collection placer of gold using various Minelab metal detectors. He dug each flake, one nugget at a time. Most if this placer material is from Arizona, but it also includes some gold from other locations. The upside down jar with the small gold contains several pounds of small flakes and pieces placer gold.
This is a fine 7.5 ounce nugget taken from the north Fork of the Yuba River in Sierra County , California The Yuba river is famous as a gold producer and has been producing gold for more than 150 years. The specimen value of this piece
River rounded placer gold looks like these nuggets. These specimens show the smoothing effects of being transported in a stream where rocks and gravel pound the gold into rounded shapes. Most of the placer gold recovered by miners is of this type. These are from the Mother Lode country in California and were recovered by the author from the Yuba River and nearby streams.
These angular pieces of gold have not been shaped by the flows of a stream. They were mined on the hilltop near the rocks in which they were formed. They are from California and were also recovered by the author.
I have known of gold specimens being sold around the western USA for a number of years that are marketed as coming from the "Mad Mutha" mine in Nevada. Well, I finally got to meet Mr. "Mad Mutha" himself at a recent mining conference in Sparks, Nevada. He uses a GP Extreme and and a Gold Bug II metal detectors to find gold. The gold he produces is very spongy, the kind of stuff that PI detectors sometimes have a bit of trouble with sometimes. The photo at left shows some of the gold he markets from the Mad Mutha claim.
I had a chance to see some gold quartz specimens offered for sale at a conference of mining folks. I wanted to post these so you all could see how expensive nice crystal gold is going for.
The next 3 photos are from the Eagle's Nest mine in Placer County. The specimens are made by treating high grade gold quartz with Hydrfluoric acid to etch away the quartz. The price on No. 3 was a bargain $4,500. I would estimate it contains about 3/4 or an ounce of gold. No. 4 is $1500 and probably has about 2 dwt of gold - I saw that it did sell at the conference. The specimen in No. 5 has a spray of gold around 3 inches tall, and probably does have 2.5 to 3 ounces of gold.
Another fine specimen from the Eagle's Nest mine in Placer County, California.
It can be seen that nice crystalline gold specimens and the specimens that can be created out of higrade gold-quartz by those with tools, talent and a few quarts of Hydro Fluoric acid. Just a disclaimer: HF acid can be very dangerous if mishandled.
Here is another fine specimen from the Eagle's Nest mine in Placer County, California.
