There have been some reports of gold dust (along with fool's gold) being found in placer deposits southwest of Hot Springs. However, since this area is highly tourist oriented, you might want to consider that this story may be perpetuated just to increase business.  There is a discussion board linked to this site that seems to have more questions than answers. The Akansas Geological Commission has a short write up documenting USGS efforts and previous AGC efforts to find gold. They have concluded that no commercial quantities exist. However, their report does confirm the placer deposits SW of Hot Springs and is likely the source of all the reports. \n\nFrom a geologic standpoint, there is little likelihood of finding gold in Arkansas. Gold is associated with hydrothermal deposits created by igneous processes (often associated with plutons). Gold is often precipitated in veins along with quartz and other minerals found in these hydrothermal waters. From the reports I have read, the few instances of this type of geologic process in Arkansas, probably related to the Ouchita Orogeny did not seem to carry gold along in the hydrothermal solutions. \n\nA gold mine operated unsuccessfully in Rogers Arkansas around the turn of the last century. http://www.rogersarkansas.com/museum/donationOfTheMonth/10-02.asp\n\nAs was true even during the 1849 Gold Rush in California, there is often more money to be made selling shovels and picks (and Levi's) than prospecting for gold. I would suggest selling your fines (gold dust) on eBay where you will likely earn more than the gold value. There are collectors of  gold nuggets and gold dust from various locales that will pay more than face value for gold in it's natural condition. Good luck and have fun.

My husband went to Lima, Peru about 15 yrs ago and brought me home some beautiful peices of silver.  They mine silver there and it is extremely reasonable.  Maybe you could try searching the web for some wholesalers out of Peru.  Just a thought.  I didn't understand you to say you were going on-line to sell these, do you have a storefront or what?

Modern mines, in Minnesota and Michigan in the US, and Eastern Canada mine taconite. Taconite is a term to describe magnetite ore that is very hard and fine-grained. Taconite must be first processed into iron oxide pellets by crushing and magnetic separation of the magnetite to concentrate the iron to about 66% before it can be used in steel-making.\n\nTaconite mining involves moving tremendous amounts of ore and waste. The waste comes in two forms, bedrock in the mine (mullock) that isn't ore, and unwanted minerals which are an intrinsic part of the ore rock itself (gangue). The mullock is mined and piled in waste dumps, and the gangue is separated during the beneficiation process and is removed as tailings. Taconite tailings are mostly the mineral quartz, which is chemically inert. This material is stored in large, regulated water settling ponds.\n\nIn Australia iron ore is won from three main sources; massive magnetite ore as at Savage River, Tasmania; pisolite "channel-iron" ore derived by mechanical erosion of primary banded-iron formations and accumulated in alluvial channels such at Robe River, Western Australia; and banded iron formation related ores such as at Newman, Hamersley and Koolyanobbing, Western Australia. Other types of ore are coming to the fore recently, such as oxidised ferruginous hardcaps, for instance iron ore deposits near Argyle, Western Australia.\n\nWorld production averages one billion metric tons of raw ore annually. The world's largest producer of iron ore is the Brazilian mining corporation CVRD, followed by Australian companies BHP Billiton and Rio Tinto Group. China is currently the largest consumer of iron ore, which translates to be the world's largest steel producing country. Iron ore is common worldwide, but commercial mining operations are dominated by the countries listed below:\n\nEstimated iron ore production in million tons for 2004, according to U.S. Geological Survey[2] \nChina 280 \nAustralia 220 \nBrazil 220 \nIndia 110 \nRussia 95 \nUnited States 54 \nUkraine 66 \nSouth Africa 40 \nCanada 31 \nSweden 22 \nVenezuela 18 \nKazakhstan 17 \nIran 16 \nMauritania 10 \nMexico 12 \nOther countries 40 \nTotal world 1250 \n[edit]\nRefining\nPure elemental iron is virtually unknown on the surface of the Earth except as wüstite from meteorites and very rare forms of deep mantle xenoliths. Therefore, all sources of iron used by human industry exploit iron oxide minerals, the primary form which is used in industry being hematite.\n\nHowever, in some situations, more inferior iron ore sources have been used by industrialised societies when access to high-grade hematite ore was not available. This has included utilisation of taconite in the United State, particularly during World War II, and goethite or bog ore used during the Revolutionary war and the Napoleonic wars. Magnetite is often used because it is magnetic and hence easily liberated from the gangue minerals.\n\nInferior sources of iron ore generally required beneficiation. Due to the high density of hematite relative to silicates, beneficiation usually involves a combination of crushing and milling as well as heavy liquid separation. This is achieved by passing the finely crushed ore over a bath of solution containing bentonite or other agent which increases the density of the solution. When the density of the solution is properly calibrated, the hematite will sink and the silicate mineral fragments will float and can be removed.\n\nMagnetite is beneficiated by crushing and then separating the magnetite from the gangue minerals with a magnet. This is usually so efficient that lower grade ore can be treated when it is magnetite than a comparable grade of hematite ore, especially when the magnetite is quite coarse.\n\nTo convert an oxide of iron to metallic iron it must be smelted.

There are zinc mines throughout the world, with the largest producers being Australia, Canada, China, Peru and the U.S.A. Mines in Europe include Vieille Montagne in Belgium, Tara, Galmoy and Lisheen in Ireland, and Zinkgruvan in Sweden. Zinc metal is produced using extractive metallurgy. Zinc sulfide (sphalerite) minerals are concentrated using the froth flotation method and then usually roasted using pyrometallurgy to oxidise the zinc sulfide to zinc oxide. The zinc oxide is leached in sulfuric acid and the resulting solution is purified using zinc dust. The metal is then extracted by electrowinning as cathodic deposits. Zinc cathodes can be directly cast or alloyed with aluminium.\n\nAnother process to produce zinc is flash smelting, a pyrometallurgical process. Then zinc oxide is obtained, usually producing zinc of lesser quality than the hydrometallurgical process. Zinc oxide treatment has much fewer applications, but high grade deposits have been successful in producing zinc from zinc oxides and zinc carbonates using hydrometallurgy.

Here is a map of US mining and mineral production:\nhttp://minerals.usgs.gov/minerals/pubs/mapdata/\n\nHere is a USGS Geographic Information System that allows you to see the location of mineral resources around the world. Go to \nhttp://tin.er.usgs.gov/mrds/\nThen click on "Browse World" on the left side. This will open and interactive map. You can turn on the data layers and refresh the map on the right hand side of the map and you can zoom in to see the data better using the icons across the top. \n\nIf you use the icon with the i in the center you can click on the small triangles on the map and you will get a location and type of mineral resource displayed at the bottom of the page. You can also build queries, and after you have made a map that you want to keep, you can print it. \n\nOther than that you can go to the Perry-Castaneda library site, where they have thematic maps of most countries, including maps and links for mineral resources. I only found one world-wide map there for mineral resources. \nhttp://www.lib.utexas.edu/maps/thematic.html\n\nIf you are looking for minerals other than economic resources, you can go to mindat.org. At that site you can search for specific minerals of all kinds, and locations are listed. \nhttp://www.mindat.org/index.php\n\nNational Geographic has a GIS that shows either coal fields or surface geology. \nhttp://plasma.nationalgeographic.com/mapmachine/

I remember that they have stored oil in disused mines. This may have been in South Africa during the apartheid years, but I am not sure.\n\nI found a link that references this: http://www.mbendi.co.za/indy/oilg/af/sa/p0010.htm\n\nThe premier engineering faculties in South Africa are the University of the Witwatersrand and University of Pretoria. \n\nTheir civil/mining engineering faculties would likely be able to help you.

Chrysotile, or white asbestos, CAS No. 12001-29-5, is obtained from Canadian serpentine rocks.\n\n    * Amosite, CAS No. 12172-73-5, also known as Grunerite or brown asbestos, is an amphibole from Africa, named as an acronym from Asbestos Mines of South Africa. One formula given for Amosite is Fe7Si8O22(OH)2.\n\n\nCrocidolite, or blue asbestos, CAS No. 12001-28-4, is an amphibole from Africa and Australia. It is the fibrous form of riebeckite. Blue asbestos is commonly thought of as the most dangerous type of asbestos (see above and below). One formula given for Crocidolite is Na2Fe2+3Fe3+2Si8O22(OH)2.\n\nNotes: Serpentine rocks are those with curled fibres. Amphiboles have straight, needle-like fibres.\n\nThe amphiboles, in their fibrous form, are friable and therefore the most carcinogenic, although they also exist in safer non-fibrous forms. Asbestos with particularly fine fibers is also referred to as "amianthus".\n\nOther asbestos minerals, such as tremolite, CAS No. 77536-68-6, Ca2Mg5Si8O22(OH)2; actinolite (or smaragdite), CAS No. 77536-66-4, Ca2(Mg, Fe)5Si8O22(OH)2; and anthophyllite, CAS No. 77536-67-5, (Mg, Fe)7Si8O22(OH)2; are less-used industrially but can still be found in a variety of construction materials and insulations and occur in a few consumer products, such as talcum powders and vermiculite. In the United States, the Environmental Protection Agency (EPA) has banned all construction-related products that have asbestos content of 1% or greater. It has also banned asbestos in all other friable (easily crushed by finger pressure) products.

I would try looking in New England, more specifically New Hampshire. Ruggles Mine is one of hundreds of pegmatite deposits in New England. Pegmatite is a valuable mineral made up of feldspar and quartz among other ingredients.

THere are gold mines throughout the world. The largest mines are in Russia and So. Africa. There are many mines in the US West, and now, with the price over $700 per ounce, there is enough incentive to start digging again. \n\nThe problem is that the "easy" gold has largely been extracted already. The remaining gold is such a small proportion of the mined ore, that it's getting increasingly expensive to process.

There's the mining guild, of course, if you have 60 mining.  Otherwise the mining spot in the lumby swamp has 7 coal rocks.  There's a few coals rocks in the Al Kharid mine, as far as I know.  And there's the hobgoblin mine in the wild.
