The famous Florence Mine as it stands now. The majority of what you see was built in 1906. About 9 million dollars in Gold was produced from this mine from 1904-1912 when Gold was $20.67 an ounce. It is now an historical landmark. Tours are given of this fabulous Mine. The Florence and Rustler #2 are the only mines in the Goldfield mining district that still have their original buildings and equipment.

The Rustler #2 Mine, Goldfield Nevada. This mine is where the miners at the famous Rogers Lease discovered exceedingly rich Gold ore, in just four months from 1906-1907, over 35,000 ounces of Gold was produced, in today’s price of Gold, that would have a value of over 45 million dollars !! During the time period of 1904-1908, it was common to find lenses of ore that assayed from 35 - 1,500 and sometimes over 2,000 ounces of Gold to the ton... The Rustler #2 and Florence are the only two mines that still have their original buildings and equipment. These buildings and head frame are from 1906.

12th Apr 2019 22:49 BSTJeff Weissman Expert

Jon, thanks for posting - all very interesting. I wonder why the old miners left such high grade ore lying around?

12th Apr 2019 23:19 BSTJon Aurich

Thanks Jeff, a good portion of the sorting, “Cobbing” was done underground, at the time, the Western mines were illuminated by candlelight, with the poor lighting, moisture and huge amounts of Kaolinite, the blasted ore and waste rock were mixed with the clay and hard to see, many high Grade specimens were lost with the waste, later, the waste piles on the surface of the mine were washed with garden hoses to reveal rich lumps of high grade ore. It has been said that around 1908, after huge down pours of rain, that the mine superintendent discovered many lumps of high Grade on the waste piles, giving the idea of washing a good portion of the lease waste piles....

This beauty is from the famous Nixon, Wingfield and Sweeney Lease on the Florence Mine. This lease is where George S. Nixon, (U.S. Senator of Nevada) and George Wingfield, (future multi millionaire) made their first money in mining. In 1905, Very rich ore like this example was discovered in this lease, over $600,000 was mined within four months, when Gold was $20.67 an ounce !! A year later, with a systematic compilation of interests of the rich mines in Goldfield, Nixon & Wingfield organized the Goldfield Consolidated Mines Company, in 1907, it became the 17th largest corporation in the U.S. the stock holders earned more than 32 million dollars in dividends in 11 years.. This Brecciated specimen contains Quartz, Bismuthinite, Milltown Andesite, Alunite, Cryptocrystalline Quartz. Dacite, Goldfieldite, Famatinite and Native Gold. Size: 3 3/4” x 1 3/4” x 3/16”.....

Mohawk Mine, Goldfield Nevada. Worthy was the Mohawk to receive worldwide praise from 1906-1918, the mine became the number one producer of the district with more than 50 million dollars in Gold produced in just 12 years, and that was when the value of Gold was $20.67 an ounce !! The Mohawk became the crowned jewel of the Goldfield Consolidated Mines Company. During the early years of the leasing period of 1906-1908, millions of dollars in Gold were produced from the Florence, Mohawk, January, Red Top, Clermont and Jumbo Mines. This rich high grade Gold specimen shows brownish rust areas all through the specimen, most of which is Native Gold. Size 6” x 3 1/2” x 3 1/2”.... Probably the only true exceedingly rich high grade specimen from the Mohawk that exists.....

. Jumbo Mine, Goldfield Nevada. The Jumbo was one of the first mines to find good ore in 1903, it was also the first mine to ship ore in the Goldfield mining district. It’s amazing that there are so many different species of high grade and milling ore. Pretty well all of the seven rich mines have their own characteristics of ore. On the Florence alone, there are 9 different species of ore that I have seen and many others on different mining claims. These specimens have different sizes..

Thank you Paul !! I’ll have to put up some more specimens, once I figure out why I cannot insert photos here or at any other thread......

John 

It may be easier turning this thread into an article and just keep updating the article.
I think it would be easier and you could easily rearrange it if need be.

23rd Aug 2019 08:31 BSTBart Cannon Expert

I believe that the first piece in the series would assay at hundreds of ounces of gold per ton.  2 ounces per ton is way low.

23rd Aug 2019 14:28 BSTJon Aurich

Hi Bart, that specimen that you referred to would have an Assay of around two ounces of Gold per pound, not per ton...   exceedingly rich ore !!

23rd Aug 2019 20:46 BSTPaul Brandes Manager

Ridiculously rich ore actually..... 12.5%!!!

Goldfield Nevada. Bonanza Ore. This High Grade Gold specimen lays in a waste pile, untouched since it was brought out of the mine and dumped by a miner from 1906-1907. Its amazing to think that this specimen would assay at hundreds of ounces of Gold per ton !! The size of the ore body that this specimen came from could have been a few tons, to 50 or even larger. Some of the ore discovered at the Florence Mine at Goldfield assayed at over 2,800 ounces of Gold per ton !!

This specimen is fantastic !! The Native Gold is running through the specimen. Rare and impressive

Goldfield is the namesake for the ore mineralization model based around quartz / alunite hydrothermal alteration.  Is alunite easy to find on the dumps ?

7th Sep 2019 17:04 BSTJon Aurich

Hi Bart, Alunite can be found on certain dumps at Goldfield, it is also associated with Famatinite and Bismuthinite in the ore. Sometimes it is in large quantities around these other Sulfides or just in minuscule areas of the ore.
