Gold's Distant Cousin - Pyrite

On a recent trip to the desert prospecting, I stumbled upon a glint in the sand. I was heading to an area when I caught a sharp flash in my left eye. Bending over for inspection, I found a small quartz pebble with what I first thought was gold.
As you have probably done in the past after the initial excitement, I discovered it only to be pyrite. I still think it is a pretty material, so I usually save it all anyway. Iron sulfide has made many a man a fool! There is a tiny vein of it diagonally and three distinct spots. Anyway, from Wikipedia -
Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold. The color has also led to the nicknames brassbrazzle, and Brazil, primarily used to refer to pyrite found in coal.The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide materials.
The name pyrite is derived from the Greek πυρίτης (pyritēs), "of fire" or "in fire",in turn from πύρ (pyr), "fire". In ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite.
By Georgious Agricola's time, c. 1550, the term had become a generic term for all of the sulfide minerals
Pyrite is usually found associated with other sulfides or oxides in quartz veins, sedimentary rock, and metamorphic, as well as in coal beds and as a replacement mineral in fossils, but has also been identified in the sclerites of scaly-foot gastropods. Despite being nicknamed fool's gold, pyrite is sometimes found in association with small quantities of gold. Gold and arsenic occur as a coupled substitution in the pyrite structure. In the Carlin-type gold deposits, arsenian pyrite contains up to 0.37% gold by weight.

The Methods and Tools of Mining in Yesteryear Were Impressive


It was the Romans who developed large scale mining methods, especially the use of large volumes of water brought to the mine head by numerous aqueducts. The water was used for a variety of purposes, including removing overburden and rock debris, called hydraulic mining, as well as washing comminuted, or crushed, ores and driving simple machinery.

Read about a number of tools the ancients used in mining in Phoenicia, Greece, Rome, and Egypt. See how modern mining techniques evolved.

Metal Detecting Locations Revealed

Want 70 ideas about locations for metal detecting? This article is very comprehensive. I have chosen many of these spots, but I must confess, I have missed about half of them. From the URL below, here is a quote. "A good site for metal detecting is an area that has been utilized by a few people over a long period of time, or an area that has been utilized by thousands over a brief period of time."
I highly recommend this read.

Whydah Sinking Described in Original Detail

"Relying heavily on a 1717 map of the wreck site – a true "pirate treasure map", Barry Clifford found Whydah's wreck in 1984 ... a discovery of unprecedented proportions. 
As Clifford describes in this National Geographic video, more than 200,000 artifacts have been retrieved including the ship's bell, inscribed with the words "THE WHYDAH GALLY 1716". 
It is definitely worth the time - see the video.

Walt Disney Gold and Silver Collectible Coins

Though I am not a coin collector, I enjoy looking at facets of the gold industry that may offer the opportunity for profit. Collectibles can afford the opportunity for profit. Here is an article about Disney coins that I found interesting.

Original News Articles About the Silver King Mine, Pinal County, Arizona

The Silver King Mine traces its beginning to 1870, during the Apache Wars General George Stoneman, desiring an easier access route to Apache strongholds, had ordered the construction of a road from Camp Picket Post into the Pinal Mountains.[The road became known as the Stoneman Grade. A soldier named Sullivan, who was assigned to the construction, discovered some heavy black rocks that flattened when struck. Interested in the rock, he collected several samples but did not mention this to his fellow soldiers.After completing his term of service, Sullivan went to work on a ranch owned by Charles Mason. Sullivan routinely showed off the rocks, known as "nugget silver" to prospectors of the region, but never divulged the location of the discovery. After a time, Sullivan disappeared and was assumed to have been killed by Apache. 
Mason, joining with Benjamin W. Regan, William H. Long, Isaac Copeland, and another companion went searching for the location of Sullivan's find. On March 21, 1875 the group was attacked by Apache and the unnamed companion was killed and buried near the summit of Stoneman Grade. Following the burial, one of the group's mules strayed. Copeland was sent to find the wayward animal, locating it near the base of Stoneman Grade. Upon finding the mule, Copeland noticed an unusual rock outcropping and upon closer inspection saw markings that had been left by Sullivan. Sullivan's find had been located.
