(What the “BLEEP” is a SULFIDE anyway??)
As of October 2018 thru 2019 the Tuscarora mine is our primary focus. The Tuscarora has over 640,000 tons of above ground tailings and mine waste. We are currently permitted, as a non-mechanized/no chemical to process 34,000 tons per year per mine. Our independent assay of the Tuscarora is as much as 1.79 ounces of gold per raw ton. Right now, thanks to the new hammer mill we just received, we will be able to process 300 to 400 pounds per hour.
Our initial goal is to produce at least 10 or more ounces of gold and other precious metals per month. At that point we will be completely self-funding and will open the other mine properties accordingly. The Tuscarora above-ground assay of gold and other precious metals is valued at over 1/2 a billion dollars. And, if we learn how to extract the Rare Earth Metals, the assay indicates the worth would be over $1 billion.
Our independent assays have verified that our Tuscarora Nevada mine has as 1/2 an ounce to as much as 1.79 ounces of gold per raw ton.
THE TRICK IS EXTRACTING IT. The gold isn't going to suddenly appear out of the rock on its own.
A combination of knowledge, skill, alchemy, metallurgy, financial backing and shear man power is what will unearth it.
A Dore' Bar is essentially raw gold plus other precious metals - it is a bar smelted from our concentrates and contain an average of 50% to 72% gold - the rest of the metals are; silver, platinum, copper, lead and various rare-earth's.
Our DORE' bars would be considered 14 to 18 karat gold. Very sellable at most gold exchanges and pawn shops - as well.
*** Eighteen-karat gold is 18/24ths, or three-quarters pure gold. Jewelry of this fineness is marked "18k" or "750," the European designation meaning 75 percent gold. In the United States, 14-karat gold is used most commonly for jewelry. Fourteen-karat gold is 14/24ths, or slightly more than one-half pure gold. ***
To obtain gold, and to make a Dore’ Bar from the gold (and other precious metals) extracted from the Tuscarora mine waste and tailing piles is a complicated process.
Working with limited funding, which we are very thankful for, has been an exceptional challenge.
Through a rough process of trial and error we have discovered that our ore is part of the Carlin Trend type deposit region that is overabundant with sulfides.
As a prime example the largest gold mine in North America is in Nevada along the Carlin Trend deposit region where as much as 10 tons of raw ore must be extracted to obtain just one ounce of gold.
Fortunately, we can concentrate the sulfides using a complex process where we finely grind the rock ore then use a vibration process causing the ore to separate from the waste rock, leaving us with a high concentrate of sulfides that are rich with gold, silver and other precious metals. This process is very effective and allows for the gold, copper, silver and platinum group metals to be concentrated into a product with much higher values and a much smaller mass than was originally mined.
Our concentrates come from the Carlin Trend deposit region and hard rock from mines in the Nevada mining district. We hand dig rock and dirt out of the mine the tailings, then run it through our mill process to crush it into sand type concentrates. That material is then run through our shaker table and then what is left in the journals is what makes our concentrates.
We don’t take gold out or add Gold into the dirt! Gold was first discovered at our mine in the 1800's.
Our precious metal concentrates are so apparent in an X-Ray Fluorescence Metals Analysis Report that we will try every avenue available to us to get them extracted.
Our Tuscarora Nevada mine tailings are part of the Carlin Trend type deposits. We're in the Nevada's Basin and Range, where the crust is stretched and comparatively thin to much of the Earth’s crust. Magma takes advantage of these types of zones of weakness and intrudes into the rocks. Water and air then circulating through the crust and gets heated by the magma then lots of stuff dissolves in it: gold, silver, copper, sulfur, iron, arsenic, and other minerals. The hydro-thermal fluid that leaves behind rich deposits of vein gold, also creates veins heavily saturated with iron sulfides.
Sulfur hasn’t always been recognized as being that important in gold recovery but research in the Carlin Trend deposit region has found that it enhances gold solubility. It is a very important step in forming a gold deposit. In many cases, in the region, detecting as much as 8 times the amount of gold if sulfur was also present.
Sulfide ores, and pyrites, have caused and continue to cause difficulty in recovering the gold values from these Carlin type deposit ores. In most instances, visible gold cannot be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to -200 mesh, a high rate of visible specs of gold can be seen under microscopic. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns down to 2 or 3 microns.
Also, the incidence of the fine gold's quantity appears to be related to the gold concentration found in the area sulfide as well. If the assay is 2 ounces per ton, there Pyrite is considered present as much as 10 times the gold content and the most common of the minerals, is iron sulfides. But the gold found encased in these sulfides is often present in its purest form.
With our Tuscarora Nevada based mine we are dealing with sulfide rich tailings that have been exposed to an additional water and air chemical reaction during the early mining processes of the 19th and 20th centuries, this chemical reaction has created a sulfuric acid base – basically a pool of dried battery acid.
We must eliminate these corrosive acids through a specific type of the gold recovery process. This is not a task taken lightly.
Millions of dollars’ worth of gold is just sitting above ground waiting to be properly harvested.
How we process our ore to liberate the contained precious minerals is determined by how and why these minerals were originally formed or deposited in the rocks hundreds of millions of years ago.
The fields of geology, mining engineering and metallurgy are requiring an in-depth understanding of the best way to find, mine and process (extract) the payable minerals.
Critically, to efficiently liberate gold from the host mineral of the particles themselves has determined the process we’ve decided to use for optimal gold recovery.
