Mining

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Sixteen to One Mine MRDS #10310678 AU

Ore shoots range from small masses of gold and quartz yielding a few hundred dollars to ore bodies yielding many hundreds of thousands of dollars. One ore shoot in the Sixteen to One mine, with a length of only 40 feet, contained nearly $1 million $20/troy ounce, while another in the Oriental Mine, measuring only 14 feet long, yielded

Gold

Gold is the most malleable of all metals. It can be drawn into a wire of single atom width, and then stretched considerably before it breaks. Such nanowires distort via formation, reorientation and migration of dislocations and crystal twins without noticeable hardening. A single gram of gold can be beaten into a sheet of 1 square metre 11 sq ft, and an avoirdupois ounce into 300 square feet
