History & Geology
Bodie, California, in its heyday, was once rumored to be one of the roughest and most lawless towns in the American West.
He found 5 to 7 feet of gravel containing half an ounce per yard. This started a rush of placer activity and several other shafts were sunk, with some large multi-ounce nuggets being found.
The Oatman/San Francisco Mining District’s historic gold production of 2.2 million ounces of gold since the 1880s makes this area Arizona’s greatest primary gold producing district.
The Reno Masonic Lodge was built along the railroad tracks back when Ulysses S. Grant was president and shortly after the Comstock Lode of gold and silver was struck in Virginia City.
My partner had the contacts and it wasn’t long before we had an agreement in place and the company had a geologist on site. I recall a time when he was getting the lay of the land, so to speak, and he broke off a rock sample and inspected it with his magnifier.
While a large number of locations have yielded some placer gold, most of the state’s placer production has come from a few productive districts.
Most of the commercial mineral deposits are on the south and southwest part of the range between Minersville and Milford, though small amounts of gold and silver have also been found in iron-rich outcrops in the basalt to the south of Milford.
The placer deposits of Utah occur in two distinct types of environments. These are 1) placers found adjacent to, and derived from, gold, silver and base-metal deposits; and 2) placers found in major rivers and derived from unknown, distant sources.
The gravels in contact with the bedrock or false bedrock base are often the richest. The same facts apply to the alluvial paystreaks that are formed on gravel bars; the lowest level of the gold-bearing gravel is normally the richest.
It is not necessary to have a PhD in geology, but you need to know the basics, so that’s what I am going to try to dig into here—the understandable basics of these gigantic gold deposits.
There are both hard rock and beach sand types of titanium deposits, but the hard rock deposits need to be at least 10 percent titanium while the beach sands often are economic with only two or three percent titanium.
…it was immediately evident the previous owner had not been using a detector. During just a few months of working the dumps part-time, he recovered gold in quartz specimens valued in excess of $40,000.
With successively lower temperatures as the water mixture cools, new sets of minerals are formed and many of those stable at a higher degree of heat became subject to alteration as the temperature progressively moved lower.
A treasure-seeking young man whose name will forever remain anonymous made the months-long journey either over land or by sailing ship to California after word spread about the gold strike in 1849.
