Yes, this made people rich; but those who became rich, sat at the top of companies and didn't get out and get dirty.

Then there are the other mineral discoveries over the years while camping in an old, $100 tent, in ghost towns, wilderness, and on the top of mountains. I walked hundreds of miles, breathed clean air, was bit by a tick, surrounded by rattlesnakes and coyotes, and met many entertaining cowboys, prospectors and geologists in local pubs. So, I am rich in memories. </p><p style="text-align: justify;">When I entered college a long time ago, my parents taught me to value what a person did with their life, rather than how much they could buy with inherited or stolen bank accounts. How sad is it to see so many billionaires and multi-millionaires who steal, build phony foundations, and give nothing back to the world, and then brag about their contributions. Good luck with the eye of the needle.</p><p style="text-align: justify;"> Those who know me realize I'm not all that bright, but I'm driven to discover. I search for mineral deposits based on science, and as soon as I find what I'm looking for, I will study the deposit only long enough to gain more insight into structure, setting, chemistry, etc, and then I move on to the next treasure hunt and leave the last one to others. </p><p style="text-align: justify;"></p><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto;"><tbody><tr><td style="text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPYnI9jjpUpGvC-RACEVlWmKPYdJRGV1j-KdD8lattwm2wLjo2C57JW_DE8_hjD928x-BBPZGmLeoMm6Qm63YRZXzmCIacaa8z2FQuEnNOuhTypVoWd-El-GPYwopWY3ov-bR4yGMGykKx/s2048/Corundum-kyanite+vermiculite+schist%252C+Wyoming.JPG" style="margin-left: auto; margin-right: auto;"><img border="0" data-original-height="1330" data-original-width="2048" height="416" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjPYnI9jjpUpGvC-RACEVlWmKPYdJRGV1j-KdD8lattwm2wLjo2C57JW_DE8_hjD928x-BBPZGmLeoMm6Qm63YRZXzmCIacaa8z2FQuEnNOuhTypVoWd-El-GPYwopWY3ov-bR4yGMGykKx/w640-h416/Corundum-kyanite+vermiculite+schist%252C+Wyoming.JPG" width="640" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;"><i>Vermiculite schist from Palmer Canyon with blue kyanite and pink-red corundum.</i></td></tr></tbody></table><br /><div style="text-align: justify;">In the 1990s, I went looking for rubies that were misidentified as garnets. After I found the deposit in Palmer Canyon in the Laramie Mountains west of Wheatland, Wyoming, I recognized other potential <a href="https://wygemstones.blogspot.com">gemstones</a> including sapphire, kyanite and possibly similar alumina-silicates. Looking, nearby; I discovered some incredibly, beautiful, <a href="https://iolite-wyoming.blogspot.com ">iolite</a>, another aluminum-rich gems. I don't think iolite and ruby are genetically linked, but they do have similarities in their geological (metamorphic) settings and rock chemistry. So, if I find another metamorphic ruby deposit, I don't believe I will always find another iolite deposit nearby, but because of these aluminum-rich rocks (meta-pelites) being formed under similar metamorphic grades (pressure and temperature), there is a chance of finding iolite and other alumina gems in the area. Some rubies and sapphires (i.e. corundum) appear to have a connection to a particular host rock known as vermiculite schist (the host for ruby, sapphire, and kyanite at Palmer Canyon), iolite does not. This association is important, and after I recognized this characteristic, I searched the literature for information on vermiculite deposits, visited them, and all of a sudden, I had another 6 discoveries. And I found some other iolite deposits based on the reported presences of a mineral geologists know as cordierite. So, yes, there is a link between geology, chemistry, setting, and even wisdom. </div><p></p><div style="text-align: center;"></div>The Gem Hunterhttp://www.blogger.com/profile/08140441375536836992noreply@blogger.com0tag:blogger.com,1999:blog-6859851055712077311.post-41984351542512457892017-06-06T09:26:00.007-07:002022-03-07T11:05:35.425-08:00Prospecting for Gemstones<div style="text-align: justify;">

I searched for gemstone deposits in Wyoming, something that was nearly unknown in the cowboy state other than jade and some agates. The more I looked, the more I found, and then I began to uncover geological clues.</div><div style="text-align: justify;">
<br />
Found more gemstone deposits and previously unknown minerals in Wyoming than any other person. More than anyone should have been able to do. After developing some good <b>prospecting</b> models for finding <b>gold</b> and <b>gemstone</b> deposits - I went searching for more mineral deposits. </div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Gemstones have unique qualities that make them attractive. If they are translucent to transparent, or have bright colors or color combinations, they could potentially be used in jewelry. Others just have unique shapes that make them attractive, such as some <a href="https://geology.com/minerals/staurolite.shtml">staurolite</a> or cordierite (iolite) specimens. Sounds simple, but gemstones were almost completely ignored in Wyoming prior to 1977, and because some geologists stated that there were none (other than jade), people believed them. But, I wasn't so sure, and after I began searching, I even found gemstones adjacent to highways and the interstate. The only other person to look for gem characteristics in minerals was Dr. J.D. Love of the US Geological Survey! Why? Well it likely goes back to education. In geology, students are not taught to look for gems - it's that simple. And instead of calling peridot "<b>peridot</b>", <b>geologists</b> call it "<b>olivine</b>". Instead of calling iolite "iolite", we are taught to call it "cordierite".<br />
<br />
Then there are <b>gemologists</b> - they can recognize <b>gems</b>, but most have no idea how to find them in the field and few have any idea what they look like in nature, since they rarely see raw gemstones. So, the education system for <b>geologists</b> and <b>gemologists</b> has this one major flaw that worked in my favor. So, do you think universities bothered to correct this flaw? Not yet.</div>

Take for instance the discovery of gem-quality <a href="https://peridot1.blogspot.com"><b>perido</b>t</a> in Wyoming. Some years ago, while searching the <b>Leucite Hills</b> near <b>Rock Springs</b> for evidence of near-surface, buried, olivine-rich <b>lamproite</b> similar to those in Western Australia at <b><a href="https://en.wikipedia.org/wiki/Ellendale_Diamond_Field">Ellendale</a></b> and <b><a href="https://en.wikipedia.org/wiki/Argyle_diamond_mine">Argyle</a>,</b> where some of the more attractive <a href="https://argylepinkdiamonds.com.au/"><b>fancy diamonds</b></a> in the world are found and <a href="https://s-media-cache-ak0.pinimg.com/736x/f0/7f/26/f07f26e96381a673f6b4e99c1a91a016.jpg">mined</a>. Nope, didn't find any diamonds associated with those lamproites, but did find some diamond-indicator minerals with good chemistry that suggest a diamond or two might be found in the Leucite Hills, while searching, I recovered over 1,300-carats of gem-quality peridot! Some famous geologists from the past looked at those same olivine crystals and saw nothing much of interest. I looked at them, and I saw gemstones!</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">In 1986, the Wyoming Geological Survey had a competent director who requested a special appropriation from the legislature to send me to Western Australia to study the newly discovered diamond pipes for about a month. Three things I brought back from Australia with me - (1) they have jack rabbits that are much taller than the Wyoming rabbits and the Aussie jack rabbits also have pockets, (2) the people speak funny, (3) and the newly <a href="https://www.bing.com/images/search?q=lamproite&qpvt=lamproite&qpvt=lamproite&qpvt=lamproite&FORM=IGRE">discovered</a> <b>diamond</b> deposits occurred in <b>olivine <a href="https://en.wikipedia.org/wiki/Lamproites">lamproite</a></b> - not <b>kimberlite</b>. And guess who had the largest <a href="http://leucitehills.blogspot.com/">lamproite field</a> in North America? That's right - Wyoming! So, I had another project for my <i>'to do' </i>list.<br />

So, after I returned from the International Kimberlite Conference in <b>Australia</b>, I went back to work mapping <a href="http://wyprospector.blogspot.com/">Wyoming's principal gold district</a> - the 500-square mile <b><a href="http://southpassgreenstone.blogspot.com/">South Pass</a> greenstone</b> belt near Lander. I don't want to get into a discussion on greenstone belts at this point, but you can read about them at <a href="https://en.wikipedia.org/wiki/South_Pass_greenstone_belt">wikipedia</a>. </div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">In 1991, I finished the <b>South Pass greenstone belt</b>, published numerous papers, eight 7.5 minute quadrangles with geology, wore out a few pairs of field boots, tipped several beers with locals at the <b>Atlantic City Mercantile</b>, mapped 3 dozen underground mines, and published a summary of the district with a 1:50,000 scale map. I was proud of those accomplishments and even found some <b>gemstones</b> in the district: native <b>gold</b> (of course), helidor beryl (which led a prospector from Lander, by the name of Elmer Winters, Jr., to find a fabulous <b>aquamarine</b> gemstone in the Louis Lake pegmatites along the western edge of the greenstone belt). Elmer (RIP), was a good friend of mine and part owner of the Duncan mine. He dug on a solid pegmatite over one weekend using an old method known as <a href="http://miningcontest.com/SINGLE_JACK.html">single jacking</a> from working in a mine. Good thing he dug it out, if it would have been me, it would have been in 10,000 pieces - but Elmer got it out in two pieces!<br />
<br />
<div class="separator" style="clear: both; text-align: center;"></div>Then, I had another project, another, and another. I mapped the <b><a href="http://seminoe.blogspot.com/">Seminoe</a> Mountains</b> <a href="https://en.wikipedia.org/wiki/Seminoe_Mountains_greenstone_belt">greenstone belt</a> north of Sinclair Wyoming, searching for <b>gold</b> and <b>gemstones</b>. The project was very positive - and at the end, I published several papers on the area, stepped on a rattlesnake, learned I could jump 10 feet high without a pole-vault, and found <b>lapidary</b> material in the <b>banded iron formation</b>, some fuchsitic quartzite, cuprite, malachite, chrysocolla, visible gold specimens at the Penn mines. Likely, the two most valuable discoveries were the occurrence of a potentially giant, Tertiary to Recent <b>gold</b> and <b>pyrope garnet</b> paleoplacer along the northern flank of the Seminoe Mountains. Actually, I did not discover <b>gold</b> in the paleoplacer. This was made by two wonderful people - Donna and Charlie Kortes! Yes, the Kortes Dam and everything else out there with the Kortes namesake, is named after Charlie and his family tree, but, if it wasn't for that mapping project, I would never have met the Kortes's, and we would most likely not know about that paleoplacer.<br />
<br />
I still remember meeting them at the <b>Sunday Morning mine.</b> They wired together a couple of step ladders and lowered me into the mine. While I was exploring the extension of the mine tunnel, the thought occurred to me - <i>"Hey, I don't even know these two. They could easily pull out the ladder and no one would find me for weeks"</i>. But, these two were absolutely wonderful, and they did let me out of the tunnel. Thank God!<br />
<br />
Anyway, Charlie and Donna took me out near the <b>Miracle Mile</b> on the <b>North Platte River </b>which I wrote about in one a <a href="https://www.amazon.com/Guide-Finding-Gemstones-Minerals-Rocks/dp/1502513889/ref=asap_bc?ie=UTF8" style="font-weight: bold;">Gemstone Book</a>. We started dry panning some of the dirt from the paleoplacer and finished panning at the North Platte - it all contained a few colors. While panning, I was more impressed by all of the <b><a href="http://gem-garnet.blogspot.com/">pyrope garnets</a></b> I found. Later, I was able to get some of the <b>garnets</b> tested for chemistry at a lab in Russia due to my connection with a co-author (Dr. Ed Erlich) on a <a href="https://www.amazon.com/Diamond-Deposits-Exploration-History-Discovery/dp/0873352130/ref=asap_bc?ie=UTF8">diamond book</a> we wrote. Later, we tested other <b>pyrope garnets</b> at the UW microprobe lab - and every garnet tested (not many as I didn't have any budget to speak of), tested to have a favorable combination of magnesium and chromian enrichment comparable to diamond inclusion garnets, that indicate somewhere in that region, there are some <b>diamond deposits</b>! So, when you are out in this paleoplacer <a href="http://searching-for-gold.blogspot.com/"><b>searching for gold</b>,</a> there is a good chance you may <a href="http://aupan.blogspot.com/">pan</a> out <b><a href="http://diamond1872.blogspot.com/">diamonds</a></b>.<br />

<tr><td class="tr-caption" style="text-align: center;"><i>After finding significant gold in the Rattlesnake<br />Hills, I published the above book and several other<br />papers.</i></td></tr>
</tbody></table>
Anyway, I next went on to map the <b>Rattlesnake Hills <a href="https://en.wikipedia.org/wiki/Rattlesnake_Hills_greenstone_belt">greenstone belt</a></b> and found evidence of gold. In addition to gold, there was a jasperoid deposit with some uncommon fossil leaf imprints. After I finished reconnaissance mapping and exploring of the <b><a href="http://rshgold.blogspot.com/">Rattlesnake Hills</a></b>, I published several more papers on the geology and mineralization of that district.<br />
<br />
So, how did I find so many gold deposits in the Seminoe, South Pass, Rattlesnake Hills greenstone belts and other mining districts in Wyoming? It was easy. I found hundreds of gold anomalies by using the following <b>prospecting </b>method. I went to places that had already been prospected! Then I lined up the prospect pits on aerial photos, and looked for evidence for additional mineralization, such as vegetation anomalies, quartz outcroppings, narrow resistant ridges (indicating silicification, i.e., veins), lineaments, and gossans. And I went searching the Rattlesnake Hills primarily because it was a greenstone belt with rocks enriched in gold, with several alkalic volcanoes that intruded the greenstone belt, providing heat engines and breccias necessary to mobilize gold from the rocks and concentrate the gold.<br />

But, they only mined what they could find that was minable at a profit when gold prices were only $20.67 per ounce. Last I looked, the gold price was just under $1,300 per ounce. Because of the high gold prices of today, we can mine a lot of material that the old timers ignored and threw away. So, if you want to find a gold deposit, examine old gold districts, figure out the controlling structure(s) (where do all of the old mine dumps, head frames and prospect pits line up), and start walking along that structure. In between each pair of mines and prospect pits, the same gold structure is still under your feet, maybe just below a few inches of dirt, but its there. But also keep an eye out for low-grade gold. At the <b><a href="http://carissa-au.blogspot.com/">Carissa mine</a></b> at South Pass, I found evidence of a giant gold deposit - a shear zone that was as much as 1,000 feet wide and more than 1,000 feet long, with a minimum depth of 970 feet deep and likely continues a thousand feet or more at depth. That is a lot of gold! And then, how much more gold has been missed from the Carissa to the Duncan and the Tabor Grand mines? Wow, there is a real gold mine out there! Now, look at these gold structures and where are they cut by streams and gullies - yep, there are gold placers down slope and stream from these. Now this is a simple prospecting method.<br />

After I found gem-quality <a href="http://wygem.blogspot.com/">iolite</a> at Palmer Canyon, it occurred in association with other <a href="http://iolite-wyoming.blogspot.com/">gemstones</a> including ruby, sapphire and kyanite. The close association of the corundum minerals with a rock type known as <a href="http://www.clays.org/journal/archive/volume%2010/10-1-61.pdf">vermiculite schist </a>led me to five new ruby discoveries almost over-night. Arthur Hagner wrote a book on <a href="http://sales.wsgs.wyo.gov/wyoming-vermiculite-deposits/">vermiculite in Wyoming</a> in 1944. I had a copy, so I read through it and after a short time it was clear to me that the aluminum-rich vermiculite was an alteration product related to relatively high-grade metamorphism and such deposits will have aluminum-rich minerals - and hopefully some of those aluminum-rich minerals will have good color and clarity and yield gemstones. Corundum (ruby and sapphire) is aluminum oxide. Some other minerals such as kyanite, cordierite (iolite), andalusite, sillimanite and staurolite are all aluminum-rich silicates created at high metamorphic pressures and temperatures. So, all I had to do was to take Hagner's book and visit all of the vermiculite deposits I could in Wyoming. I couldn't get access to all, but five yielded rubies. For those of you who would like to find a ruby deposit for yourself, try doing the same in Montana and you will likely find some ruby deposits.<br />

After finding iolite in <a href="http://iolite-wyoming.blogspot.com/">Palmer Canyon</a>, other discoveries were made. These included a half-dozen ruby-sapphire (corundum) occurrences, and a couple of kyanite deposits. I was amazed at how many gemstones, diamonds, and gold deposits had been overlooked.</div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
But there are still more gemstone deposits to find. Based on geological models, many more deposits of diamond, ruby, sapphire, garnet, zircon, spinel, kyanite, varisite, minyulite, emerald, gold, helidor, aquamarine, staurolite, sillimanite, iolite, opal, agates, jasper, specularite, labradorite, chromian diopside, etc, are likely. There is even one deposit listed as gem-quality garnets in the Hartville uplift, that has yet to be investigated. </div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">As you think about rubies and sapphires, keep three rock types in mind while prospecting in Montana, Wyoming Colorado, Utah, and California: <a href="https://geologyscience.com/rocks/skarn/">skarn</a>, <a href="https://en.wikipedia.org/wiki/Vermiculite">vermiculite</a> schist, and <a href="https://www.sandatlas.org/serpentinite/">serpentinite</a>! These are possible host rocks for ruby and/or sapphire. To find out more about these, characteristics of <a href="http://www.amazon.com/Guide-Finding-Gemstones-Minerals-Rocks/dp/1502513889/ref=sr_1_1?s=books&ie=UTF8&qid=1423159510&sr=1-1">ruby, sapphire</a> and their <a href="http://www.amazon.com/Gems-Minerals-Rocks-Wyoming-Prospectors/dp/1439218560/ref=sr_1_2?s=books&ie=UTF8&qid=1423159510&sr=1-2">host rocks</a> are described in a couple of recent books.</div>

When you think of <strong>ruby </strong>and<strong> sapphire</strong>, you probably think of spectacular, faceted, over-priced gems in rings and necklaces. Unfortunately, mother nature does not facet gems: so a gem prospector must learn to recognize the natural, physical, characteristics of this gem to identify raw material in the field. And a prospector also needs to learn where to look in the field, and how to identify possible host rocks. <br />
<br /><div style="text-align: justify;">Some time ago, I received a 25-year longevity pin from the State of Wyoming for my service to the State. It was a tiny, plastic pin about the size of nickel that had a tiny, red, ruby. So, I took this spectacular gem to my lab to examine with a binocular microscope, and it was obvious that it was a synthetic ruby almost too tiny to weigh. The ruby may be worth about $1.00 and and the pin another $1.00 (pre-<a href="https://www.frontpagemag.com/fpm/2021/12/bidenflation-soars-while-biden-fiddles-joseph-klein/">Biden</a> prices). No idea where it was made, but my guess is China. If the state government had any creativity, one would think they would search for a good, Wyoming rock hound to dig some Wyoming rubies (and other gems), facet them, and make them into longevity and dedication pins for their employees. As such, Wyoming would actually contribute to the state's economy and also provide a great means of advertising for the state's natural resources. Employees would be proud, particularly after they learned a little information about the history and gemology of the gems! </div>
<div style="text-align: justify;"><br /></div><div style="text-align: justify;">When it comes to learning to identify minerals, there are flaws with most gemstone and mineralogy books - they are not designed for prospectors or rock hounds. Essentially, all books show spectacular, faceted, gems or museum-quality mineral specimens that are rare. </div>

The two photos above show the characteristic <a href="https://geology.com/minerals/crystal-habit/">crystal habit</a> of corundum (geologists' term for ruby and sapphire). The upper photo shows a cross-section of ruby in schist with a characteristic hexagonal (6-sided) crystal habit, while the lower photo shows another corundum (pink sapphire) with its crystal habit perpendicular to crystal in the upper photo. This lower mineral is still hexagonal, but now we are viewing the long, crystal axis, which shows what geologists call a prism (or prismatic crystal habit). One mineral that is sometimes mistaken for ruby or sapphire, is garnet. But don't feel bad as I've known geologists who make that same mistake.</div>

Ruby and sapphire exhibit atomic flaws known as crystal <a href="http://www.galleries.com/minerals/property/parting.htm">parting</a>: linear, structural (atomic) planes in a crystal. This are actual planes in a mineral that gemologists might to break a mineral, or avoid when cutting the mineral, because they are a zone of weakness in the crystal. These are useful in identifying minerals like corundum (ruby, sapphire) and they do not appear in garnet. Few people are familiar with the term 'parting', but it is similar to mineral "<a href="http://www.galleries.com/minerals/property/cleavage.htm">cleavage</a>". Corundum (sapphire and ruby) typically exhibits <a href="http://www.galleries.com/Corundum">three</a> directions of parting.</div>

Corundum (H=9) is the second hardest naturally occurring mineral: only diamond is harder. As a result, gemstones made from corundum are durable. Raw corundum occurs as barrel-shaped hexagonal prisms with rough, rounded surfaces often exhibiting distinct parting. Because of good rhombohedral and basal parting corundum prisms often terminate at basal pinicoids & display striations due to repeated twinning.</div></strong>
<div style="text-align: justify;"><br /></div><div style="text-align: justify;">Corundum exhibits a variety of colors including gray, grayish green, blue, pink, brown, red & purple. Some corundum is used to produce extraordinary gemstones. <strong><span style="color: #cc0000;">Ruby</span></strong> is the deep pigeon’s-blood red translucent to transparent variety of corundum with adamantine luster and <strong><span style="color: #6fa8dc;">sapphire</span></strong> includes all other colors.</div>
<div style="text-align: justify;"><br /></div><div style="text-align: justify;">It will display a striking adamantine to vitreous luster noticeable in faceted gemstones. High specific gravity (4 to 4.1) is favorable for its concentration in black sand concentrates in streams. During sampling in the central Laramie Range, we recovered tiny rubies and sapphires in several sample concentrates in that region, suggesting that several corundum deposits remain to be discovered.</div>

</tbody></table><div style="text-align: justify;">Metapelite may contain a variety of alumino-silicate porphyroblasts such as mica, kyanite, sillimanite, andalusite, vermiculite & cordierite. The corundum itself is typically found in vermiculite schist and aluminum-rich serpentinites. Vermiculite schist is considered an alteration product of a former metapelite in which metapelite was desilicated leaving mica-rich rock known as vermiculite schist or glimmerite schist. After noting the close association of vermiculite & ruby, I discovered several more ruby deposits in Wyoming. This was also true of iolite and pelitic schist. Using geology proved to be extremely valuable.</div></div><div>
<div style="text-align: justify;"><br /></div>
<strong><div style="text-align: justify;"><strong><span style="color: #3d85c6;">Localities</span></strong>. Corundum has been found at a number of places in Wyoming. Wyoming could easily develop a major ruby and sapphire industry along with many other commodities - such as diamond, gold, palladium, rare earths, iolite, labradorite, copper, zinc and silver - but its political regime with the US Forest Service have worked for more than 30 years to withdraw nearly all non-energy mineral resources from public lands - something that should be considered illegal. Over the years, we provided evidence for major and world-class mineral deposits and several companies found significant base metal deposits, only to find government interference at every level.</div></strong>

The corundum forms small, hexagonal, pink, red and white grains from about 0.1 to 0.3 inch across. Many grains have well-developed parting which limits the size of facetable material. Even so, significant percentages have excellent color, and are transparent to translucent (Personal field notes, 1997). Locally, the schist may contain >20% corundum.
