  • (A Method) Return to Cookie Mountain is the third full-length album by the American rock group TV on the Radio.
  • The process or industry of obtaining coal or other minerals from a mine
  • the act of extracting ores or coal etc from the earth
  • laying explosive mines in concealed places to destroy enemy personnel and equipment
  • (mine) get from the earth by excavation; "mine ores and metals"
  • made from or covered with gold; "gold coins"; "the gold dome of the Capitol"; "the golden calf"; "gilded icons"
  • An alloy of this
  • A yellow precious metal, the chemical element of atomic number 79, valued esp. for use in jewelry and decoration, and to guarantee the value of currencies
  • A deep lustrous yellow or yellow-brown color
  • coins made of gold

Geological Methods in Mineral Exploration and Mining
This practical step-by-step guide describes the key geological field techniques needed by today's exploration geologists involved in the search for metallic mineral deposits. The techniques described are fundamental to the collection, storage and presentation of geological data and their use to locate ore. This book explains the various tasks which an exploration geologist is asked to perform in the sequence in which they might be employed in an actual exploration project. Hints and tips are given and the steps are illustrated with numerous examples drawn from real programmes on which the author has worked. Traditional skills are emphasised to show how they can be combined effectively with modern high-technology approaches. For instance this second edition also reviews new techniques geophysics along with GPS applications in exploration and the application of state-of-the-art software to mapping, 3D modelling and resource estimation. Another important facet is the discussion of harm minimisation, especially during the exploration stage, beginning with landowner and community consultation, through exploration planning, leading to sustainable and environmentally responsible mining practices.

Miner and gold mine drill
Miner and gold mine drill
Charlie, a fourth-generation miner, shows a modern mining drill inside the depths of Sutter Gold Mine. The drill is power by compressed air piped in from above ground and also has water running through it to cool the drill and keep silica dust from becoming airborne and causing silicosis, which is deadly. The drill is used to make holes that are filled with explosives and detonated to blast away rock to get to quartz veins that hold gold deposits. Among the tidbits of info gleaned from Charlie, we were told that there is some real background to the Snow White and the Seven Dwarfs song "Whistle While You Work". The dwarfs are miners in the Disney Animation. Charlie pointed out that the explosives handlers, called powder monkeys, had to whistle while they handled dynamite, because the nitroglycerin would leach out of the dynamite sticks and be absorbed through their skin. One symptom of excess nitroglycerin in the system is numbness of the lips, which makes it hard to whistle. So if a powder monkey stops whistling, the others would get him out of the mine as he was likely to pass out in a few minutes. I guess this was in the times before rubber gloves, so it could have been true as late as WW2 era? Also, all miners have their own methods of high-grading, which is trying to keep some of the gold ore for themselves. Today's mines have metal detectors, although Charlie claimed that some miners still had ways of getting around them.

This is Homestake's Open Cut Mine, one of the best known landmarks in the Black Hills. It is the site of the original discovery in 1876 of the Homestake claim, named for "making a man rich enough to make his home stake (enough money to return home and live comfortably)". Homestake mined this area periodically from 1876 to 1998. Two noteworthy expansions of the Open Cut occurred in the 1980s -- the first in the north end and the second and much larger expansion toward the south. Both projects employed conventional open pit mining methods involving drilling, blasting, and hauling. Haul trucks capable of holding 85 tons of material were used to move the ore to a mill for processing. Left behind was waste rock -- rock with no economic value -- that had to be moved to access the gold ore. The Open Cut is 1200 feet deep and one-half mile wide. In open pit mines such as the Open Cut, waste rock is stacked in waste rock facilities and then reclaimed (restored to beneficial use). Of the three peaks seen here, the Bobtail and Highland are waste rock facilities, while Rhyolite Peak -- with its bands of light and dark rock -- is Mother Nature's work, and may be up to two billion years old. Two additional waste rock facilities are located near the Open Cut but unseen from this view -- the East and Sawpit.
