GOLD Gold was first discovered by the Spaniards in the Pot Hole area, near Yuma Arizona. The first mining operations began in the Quijotoa Mountains as early as 1774. Seventy years later, the gold rush spawned massive gold discoveries in Yavapai, Mohave, and Yuma counties. Since then, gold has been discovered almost everywhere in the state. Placer Deposits A placer deposit is a concentration of a natural material that has accumulated in unconsolidated sediments of a stream bed, beach, or residual deposit. Gold derived by weathering or other process from lode deposits is likely to accumulate in placer deposits because of its weight and resistance to corrosion. In addition, its characteristically sun-yellow color makes it easily and quickly recognizable even in very small quantities. The gold pan or miner's pan is a shallow sheet-iron vessel with sloping sides and flat bottom used to wash gold-bearing gravel or other material containing heavy minerals. The process of washing material in a pan, referred to as "panning," is the simplest, most commonly used, and least expensive method for a prospector to separate gold from the silt, sand, and gravel of the stream deposits. It is a tedious, back-breaking job and only with practice does one become proficient in the operation. Thankfully, technology finally caught up with our gold fever and brought us metal detectors! You can always ask for permission to hunt on any private property, but there are also several places you can pan and metal detect in public access areas. As always, please respect other's claims. The following Public Access Areas are controlled by the BLM (Click Here) or the National Forest Service (Click here). Contact the designated authority for more information including maps and regulations.
GEMS Arizona is one of five States that has commercial production of gem garnets. Arizona's gem garnet is red pyrope from two locations in the extreme northern portion of Apache County on the Navajo Indian Reservation. One location is at Garnet Ridge which is about 8 km west of the town of Mexican Water, and the other location is in Buell Park on the Arizona and New Mexico border, about 16 km north of Fort Defiance. Faceted stones cut from materials from these locations average 1/2 to 1-1/2 carats in size, but stones as large as 5 carats are known from these locations. Additionally, fine-quality andradite specimens, some suitable for cutting, are available from an area near Stanley in Graham Co. Arizona is well known for its petrified wood because of the Petrified Forest National Park, and petrified wood ranks third in value of commercially produced gemstones. It is generally accepted that the Park contains the most colorful examples of silicified logs in the world. Petrified wood occurs in every county in the State, but the commercial production is essentially from privately owned lands in Navajo and Apache Counties near the Petrified Forest. Federal regulations restrict collecting petrified wood on public lands to 250 pounds plus one piece per person per year, none of which is supposed to be sold commercially. The regulation essentially eliminates production from federal lands. Pieces as small as 1/4-inch to sections of logs 5 feet in diameter are recovered from the surface of the ground or with minimum excavations for use in the lapidary trade. Arizona petrified wood has the broadest range of applications of any gem material produced in the State. The material is suitable for tumble polishing for use in baroque jewelry or for cutting into cabochons for jewelry and display. Freeform and calibrated slabs are polished for pen and pencil set bases and bases of other items, and polished slabs are used for clock faces. Additionally, large blocks, limb sections, and geometric shapes are used as bookends and decorator pieces. Objects of art, principally carvings, are produced, and furniture such as coffee and end tables are made from the petrified wood. Arizona is the only State currently to have commercial production of fire agate. Fire agate is a form of chalcedony which contains inclusion of iron oxides that result in a play of colors much like that of precious opal. Eleven operations in Arizona report either commercial production of fire agate or dig-for-fee production. The material is produced in Graham, Greenlee, Maricopa, Mohave, and Yuma Counties. Fire agate is cut into freeform and calibrated cabochons for use in the manufacture of silver and gold jewelry. The material is popular in the southwest and with hobbyist lapidaries throughout the United States. Fire agate also has been used and is currently used in Indian style jewelry. Large, fine-quality brownish to yellow colored stones have been cut from scheelite crystals from a deposit in the Hualapai Mountains in Mohave County. Some of the finest-quality, bright red facet grade wulfenite in the world comes from the Red Cloud Mine in Yuma County. Small to medium-sized pieces of light brown bytownite from Arizona and New Mexico can be faceted into 0.5- to 2-carat, eye-clean stones. Two commercial mining operations in Arizona produce blue precious opal. The body color is a light or pale blue with strong play of color in red, blue, green, and orange. The two operations sell most of its material as finished stones at the Tucson Gem and Mineral show and other local gem shows. Currently, the United States is the basic suppler of peridot to the world gemstone industry. Deposits in Arizona are the major source of U.S. peridot. Faceted Arizona peridot is highly prized locally, but also enjoys widespread popularity for the manufacture of birthstone and other jewelry. The bright green, yellow-green to olive-green peridot is used both as a faceted and tumbled gem. The faceted stones are used in rings, earrings, pendants, bracelets, and as accent stones. The tumbled gems can be set in baroque jewelry, drilled and strung as beads, used in mosaics, and in the manufacture of gem trees. Peridot Mesa, located on the San Carlos Apache Indian Reservation east of Globe in Gila County, is the most productive locality for peridot in the world. A second Arizona location from which peridot is recovered is Buell Park Apache County, Arizona, about 16 kilometers north of Fort Defiance. However, it is estimated that 80% to 95% of the world's production of peridot comes from the San Carlos Reservation. The peridot occurs as individual grains and aggregates of grains in a basalt which is about 3 to 35 meters thick that forms the top and sides of Peridot Mesa. The material is recovered after it has weathered out of the basalt, in the gullies and canyons which lead down the sides of the Mesa or it is recovered in place in the basalt. The latter method of recovery requires drilling and blasting. The peridot grains that are commercially recovered are typically 6 to 13 millimeters in size. Therefore, the faceted stones produced from this material are generally about 1 carat in size; 2 to 3 carat stones are not uncommon, but stones, particularly flawless ones, 5 carats and over are unusual. Stones as large as 15 and 22 carats have been cut from San Carlos peridot. On the Reservation, peridot can be mined only by individual Native Americans or by individual families of Native Americans from the San Carlos Reservation. In the past, the miners have not marketed the peridot directly to the gemstone industry. They marketed the material in random size lots, from as small as a coffee can full to as much as a 55-gallon barrel full, to local brokers or mineral dealers. These local brokers/dealers may or may not sort and grade the material, but they do tend to market to the industry in uniform size lots. Currently, some of the large volume miners are marketing the material directly to the industry and are also contracting for cutting services and are marketing cut stones. In Arizona turquoise ranks first in terms of value of production and is also the best known of its gem materials. As stated earlier, nearly all important deposits of turquoise are located near copper occurrences or in copper deposits in arid desert regions of the world. Thus, the world famous turquoise deposits associated with certain of the large Arizona copper deposits are to be expected. Turquoise is or has been mined from a number of these copper mines as a byproduct, usually by outside contractors. The financial and operating terms of the collecting contracts vary from mine to mine. Some of the operations are little more than the efforts of individual commercial collectors. Some are essentially full-scale mining operations that are simultaneous with, but separate from, the regular mining operations; and still others operate on an on-call basis as turquoise is uncovered by the regular copper mining operation. Regardless of the size or the sophistication of the initial mining or recovery operation, the actual turquoise is recovered by careful extraction using hand methods. COINS, JEWELRY, & RELICS Arizona offers many incredible opportunities. If this is your interest, here's a few ideas to get you started:
LOST TREASURE As in other areas of the US, there are
several tales of lost treasure in Arizona
concerning caches buried for safety. In many of these stories,
people either died or forgot where they buried the stash.
Contributing factors include: 2. Distrust of banks during the Great Depression.
