Arizona, the Copper State, not only has considerable copper, but is also rich in gold, silver and other metals. More than 16-million ounces of gold and 500-million ounces of silver mined in Arizona since the 19th century, places the state as 8th largest gold producer in the US!In this book, the author guides you to gold deposits in several mining districts, mines, and prospects using his experience as a gold hunter - a member of a geology team that found one of the largest gold deposits in history. So, take the opportunity to tap into the author's experience in searching for gold in Arizona. Prospects and mines are discussed with Public Land Survey System (PLSS) locations and/or GPS coordinates so you can visit these gold properties using aerial photography and satellite imagery available on the internet. If you visit these in the field, access and ownership is left up to reader, as mining properties and prospects often change ownership or are abandoned. The best advice for any prospector, rock hound or geologist, is learn about geology along with prospecting techniques. Any discussion on prospecting requires some knowledge of geology, so geological terms are used throughout this book with explanations. Start your search in known gold and silver mining districts - these have proven mineral deposits. Remember, the old timers found some gold and silver, but they also overlooked many deposits and ignored those that were too low-grade to mine at low precious metal prices of the past. Today's gold price is 40 to 75 times higher than in the distant past, suggesting many so-called, 'mined-out' gold properties, could still have considerable ore. As an example, some past commercial gold mines were closed during World War II to focus industry on mining primary and recycled metals needed for the war effort (copper, manganese, molybdenum, iron, chromium, lead, zinc, etc). Many of these gold mines remain a casualty of the war and did not reopen. But, if commercial at a $35/ounce gold price in 1942, they are likely commercial at recent gold prices ($1,200 to 1,500 per troy ounce). As you search for gold prospects, look for mine symbols on topographic and geological maps, and search for linear patterns of mines and prospect pits suggesting possible, continuous, linear, mineralized, fractures, veins, and structures (trends) that likely have considerable unprospected ground in between prospects. As you prospect, be careful around old mines - there are thousands in Arizona, and most have hazards you may not be familiar with such as rattlesnake dens, shafts and stopes in the middle of tunnels, unstable rock, bad air, and unstable dynamite to name a few. Most elect to search for gold in nearby drainages and stay away from mine hazards. But in Arizona, you must be aware of land ownership, weather changes, flash floods and excessive heat. And if you explore southern Arizona, illegal aliens and drug cartels are another concern and some may be heavily armed. So, when you prospect, use caution and good judgement - and remember, you are responsible for your own actions and decisions. Gold is found in many wet and dry placers, and gold and silver also occur in veins, replacement deposits and fault-controlled deposits such as those mined by Wyatt Earp and Doc Holiday in the Tombstone Hills. Other gold deposits include rich veins at Vulture near Wickenburg, and extensive prolific, structurally-controlled, gold veins surrounding Oatman. Wet placers occur along the Colorado River near LaPaz, Bullhead City, and Lake Havasu City in western Arizona. Other placers of note include Lynx Creek south of Prescott, and many dry gold placers such as those surrounding Quartzsite and Yuma.

Follow in the footsteps of successful gem and gold hunters and search the hills for rough diamonds, colored gemstones, lapidary minerals, precious metals and interesting minerals and rocks. Written for the geoscientist, prospector and rockhound; the first part of the book focuses on physical characteristics of gems and minerals. This is supplemented with the second part of the book that describes dozens upon dozens of colored gem, diamond, gold, mineral and rock localities using the Public Land Survey System and GPS coordinates so the reader can visit these sites on a home computer with aerial and satellite imagery to gain an understanding of what to look for in the field. With these same coordinates, the reader can visit some occurrences, deposits and areas suggested for prospecting to further their gem hunter prospecting education and potentially lead to new discoveries. Now you can learn what to look for when searching for Mother Nature's treasure.

Increased leisure time and increased interest in the out-of-doors is leading more and more families to experiment with placer mining of gold, and sometimes even to going on into small-scale production. This book supplies basic information on areas of occurrence, equipment needed, prospecting, sampling, mining, and regulations concerning the possession and sale of gold. Selected references are given for further study. Placer gold has tantalized many a person who has tried his luck and skill in the hope of striking it rich. Separating gold from embedded materials is basically simple, and can be done effectively on nearly any scale, depending upon the deposit and the capital available for investment. The final product is consistently in demand at a relatively stable price. Historically, however, one must be advised that rewards for the majority of small-scale miners-those who operate "on a shoestring"-have been depressingly small. First of all the placer miner must know where the placer deposits are located and he must have the technical knowledge to extract the gold. Additionally, he must face problems of land ownership, water supply, and water pollution, all of which have grown in complexity with the population. The costs of labor and equipment are relatively high now, although this may not seem significant to an individual mining a small deposit. Secondhand equipment may become available at relatively low cost because of a slowdown in construction or as surplus at the end of a war. By taking advantage of such opportunities, one can sometimes make an otherwise unprofitable operation successful, at least as long as the equipment holds up. To the novice or "weekend prospector," the more complex of placer mining may seem hard to comprehend. At any rate, the novice is often more interested in the recreational values offered by gold placering than in its profitability. Thus, the search for and discovery of even a small grain or nugget of gold is an achievement worth of considerable effort. As a start, the beginner may gain some benefit from visiting one of the many pan-for-a-fee tourist establishments typically found in gold-mining areas.

This book introduces the Original Nation scholarship to examine the historical genealogy of the nation’s struggles against the state. A fundamentally different portrait of history, geography, politics, and the role of law emerges when the perspective of the nation and peoples is placed at the center of geopolitical analysis of global affairs. In contrast to traditional and canonical state-centric narratives, the Original Nation scholarship offers a diametrically distinct “on-the-ground” and “bottom-up” portrait of the struggle, resistance, and defiance of the nation and peoples. It exposes persistent global patterns of genocide, ecocide, and ethnocide that have resulted from attempts by the state to occupy, suppress, exploit, and destroy the nation. The Original Nation scholarship offers a powerful and widely applicable intellectual tool to examine the history of resilience, emancipatory struggles, and collective efforts to build a vibrant alternative world among the nation and peoples across the globe.

The paragon of physical perfection and a sparkling example of Earth's forces at work, the diamond has fascinated all realms of society, from Russian tsars and Hollywood stars to scientists and brides-to-be. The Nature of Diamonds is an authoritative and richly illustrated look at nature's most coveted gem. Leading geologists, gemologists, physicists, and cultural observers cover every facet of the stone, from its formation in the depths of the Earth and its explosive ascent to the surface, to its economic, regal, social, and technological roles. The book takes the reader to cutting-edge research on the frontiers of diamond exploration and exploitation, from Arctic wastes to laboratories that create industrial diamonds for cutting tools that slice through rock. Charting the history of mining from its origins in India and Brazil, the book follows the diamond rush in South Africa to today's high-tech enterprises. It provides a glimpse into the economics of the diamond trade, and an overview of diamond cutting, from the rough uncut stones in early Indian and Roman jewelry to the multifaceted stones we see today. The cultural history of the diamond as both a revered and a social symbol is explored, from its early history as the exclusive property of royalty to today's brilliant-laden jewelry as an emblem of wealth and status. The engaging text is complemented by more than 200 lavish illustrations which span fine art, earth science, and cultural studies and capture the brilliance and beauty of this extraordinary gem.
