r <br />began reworking the tailings from the first operation. They <br />found that the tailings contained what they described as a <br />new formed amount of gold. <br />I have witnessed this same type of reaction on gold <br />ores that were mined in the Ironsprings Divide. I worked <br />with my Father and Mother and Great Uncle, sluice gold <br />from a mining property in this area when I was ten years old. <br />When I learned to pan, my job was to check our recovery <br />by panning the tailings for gold that we had lost. When I <br />checked the tails I did not find very much gold. After the <br />tailings set for a long time they would change color. I <br />decided to pan some of these tailings and found that there <br />was more gold in the tailings than there should have been. <br />This mystery. stayed in my mind for many years. <br />We used the advice of one of the guys from the Bureau <br />of mines on how to have the ore assayed. We were told <br />that you should send a split of the same sample to several <br />assayers. The results were so different that we did not know <br />which report was correct. <br />This is why I started studying all the information on <br />different ways to treat and assay different types of ore. This <br />way if I found gold in the sample then I knew there was gold <br />in it and did not have to wonder if an assayer report was <br />true. The source of where the gold came from that is in the <br />Ironsprings Divide has been a mystery for many years. The <br />early day prospectors and miners searched all the surrounding <br />areas trying to find the source and failed. President Herbert <br />Hoover wrote a report on the area and stated that the gold <br />does not show evidence of being transported very far. The <br />gold is angular and has sharp edges and is not typical of gold <br />that-has. een transported for long a distance. Herbert Hoover <br />stated that the gold looks as it has come from decomposed <br />tellurides and sulphide 4-he,gold appears to have been <br />decomposed after it was deposited`Tha`aSGS produced a <br />map and a preliminary report on this same in-1-96, and <br />could not find the source of the heavy mineral suit and the <br />gold. <br />My family and I have assayed many samples from <br />this area. When we found the sulphide deposit, we thought <br />we had found the source of the gold. We fire assayed many <br />hundreds of samples from this sulphide ore. Our results <br />varied a lot, but most only showed a trace to .02 ounces <br />per ton. We ground a large sample and table concentrated <br />some of the sulphide ore hoping it would reveal more gold. <br />I panned a sample of this concentrate and it was not very <br />good, so the rest of this concentrate was stored on a shelf in <br />the lab. I can recall when we found out that the sulphide did <br />contain a lot of gold. It was on January 2, 1969 and there <br />was a lot of snow on the ground. My cousin was working <br />with a uranium ore that contained some sulphide, and he <br />wanted to compare our sulphide to his. When he called me, <br />I told him the only sample of sulphide we had was one that <br />we had table concentrated around a year ago. I explained <br />that there may not be very much sulphide left because it <br />had oxidized a lot. When I finished panning the sample I <br />got a very big surprise, it contained a lot of free gold. The <br />larger unit we built worked fair, but the pressure that the <br />roast made was too much for the unit to control. I tried to <br />obtain some help from a lab in Nevada that was headed by a <br />Mr. Kenneth Broadhead. I sent him two samples of ore, both <br />were from the same head ore only one sample I treated and <br />the other was untreated. Mr. Kenneth Broadhead sent me <br />an assay that showed the following results, the roasted 6.31 <br />ounces per ton gold and .441 ounces per ton platinum. The <br />untreated showed .005 ounces per ton gold and .009 ounces <br />per ton platinum. After I reviewed the reports, I called Mr. <br />Broadhead and asked if he could explain the difference in <br />the two samples. I explained that both were from the same <br />head sample, only one was roasted and one was not.. Mr. <br />Kenneth Broadhead told me the name of the chemist that <br />would be doing the test and to send another sample and <br />include the instructions on,how to roast it. I sent the sample <br />and felt that here was the opportunity to finally get some <br />real backup on this complex ore. hen I received the report <br />the results were the same as the first untreated sample, next <br />door to nothing. I then called the chemist that was supposed <br />to follow my instructions and asked him how you treated the <br />sample. He stated I did not feel that your method was"eeded, <br />so I treated it my way. I argued with him but just wasted my <br />-breath. I wish I would have had a copy of the Russian article, <br />that was described earlier in this document, and then I could <br />have shown him that-the-procedure is widely used by some <br />of the top chemists in the assay of precious metals. <br />Carpco Inc. ran some separation tests on a concentrate <br />that was obtained from some of the placer material that came <br />from the Ironsprings Divide. All the free gold was removed <br />from this sample. After these samples were separated, they <br />were sent to the University of Georgia for microprobe work. <br />The values are reported in percentages and very interesting. <br />They found .1 in gold and 1.2 to 8.0 in iridium (a platinum <br />group metal) and identified some platinum. The major <br />mineral the sample contained was monazite. In addition <br />the University of Georgia performed quantitative chemical <br />analyses of the monazite and iridium. The report shows that <br />the rare earth concentration in the iridium contained Gd203, <br />Dy203, Ho203, Er20, and Yb203. This shows that these rare <br />earth metals were in combination with the iridium. This <br />would explain why a sample of the rare earths that was tested <br />earlier by another geologist showed the specific gravity to be <br />15 to 16; all the rare minerals are much lighter than this. <br />I found another method that worked on releasing the <br />gold, but it was very time consuming. This new method <br />would vary from four to eight weeks on each different <br />sample on the time it took to release the gold. I have now <br />developed a method that after five minutes of leaching can <br />be panned and free gold can be seen. Most samples need to <br />leach around one or two hours to show the best results. Most <br />of the gold that is liberated is in very fine particles, with the <br />exception that some of the gold will form tiny spheres (tiny <br />round beads). The sample will show copper colored, silver <br />colored, grey colored pieces of metal that has the same shape <br />as the gold. <br />I am building a grinding unit that will handle around <br />three hundred pounds of ore. The largest sample that I have <br />treated was one hundred pounds and took me several hours <br />to grind it in a small Bico disk mill. I had to save the tailings <br />and retable those several times to recover the gold. I then <br />fire assayed the concentrate and recovered 1.45 grams of <br />gold. I have the documents and assays to back up the reports <br />above. <br />Mr. Zimmerman owns and operates the Blue Jet <br />Mning Inc. company based in Colorado.
