gold ore shoots

Ore shoot Wikipedia

In mining and geology, an ore shoot is a long seam of mineral or metal bearing rock that can be profitable to extract. The term may have originated in the 17th and 18th centuries when various theories existed on the origins of ore deposits, including some that suggested they grew like trees.

GOLD RUSH: Ore Shoots and How to Trace Lode Veins

Mar 28, 2013· Ore Shoots and How to Trace Lode Veins The Duncan mine and mill as they appeared in 1977 (photo by Dan Hausel). Prospectors need to focus on finding ore shoots in veins. Nearly all veins in gold districts will have some gold and silver, but the values are alway erradic. Thus if you were able to follow a vein for some distance you will likely

GOLD RUSH: Ore Shoots

Many chemically formed ore shoots yield good ore deposits. During vein formation, hot silica (quartz-rich), hydrothermal acidic fluids react with rocks with favorable chemistry; particularly rocks with calcium carbonate (limestone, dolomite). Thus, following a vein that cuts through limestone could lead prospectors to find skarns, replacement deposits, etc for gold and other valuable minerals.

Gold in Wyoming: The Lewiston Gold Mining District, South

Gold placers occur downstream from the shear structures in Strawberry Creek, Deep Creek, the

Prospecting for Gold The GOLD HUNTER

Ore shoots. Many veins have sporadic gold values with localized ore shoots enriched in gold. Some of these shoots may be enriched 100 to 1000 times the average value of the vein. The challenge given the prospector is how to recognize these shoots. Ore shoots can be structurally or chemically controlled.

GOLD-BEARING VEINS AND SHEAR ZONES

Difficulty in blocking out ore shoots was one of the major obstacles to large-scale development of the deposits. Geochemical sampling of surface exposures indicates that in most places the veins and shear zones contain 0.1 to 5 parts-per-million gold; the highest value obtained was 18 parts per million. A. A.

Prospecting Lode Gold Deposits

Prospecting for lode deposits begins with a search for mineralized outcrops, the key to the existence of which may often be found in mineralized float (pieces of rock from the lode that have been loosened by weathering and washed downhill). Geologists now generally agree that most valuable mineral deposits have a magmatic origin and, therefore, that the most promising areas to prospect are in

Gold ore shoot development in the Antamok Mines

Various possible ore shoot controls in the Antamok mines have been recognized by using actual veins as models. The results indicate that ore shoots are of two distinct types: (1) subhorizontal pitching ore shoots and (2) moderately to steeply pitching ore shoots.

» The Basics of Successful Gold Mining-Part 1

Some people get into gold mining as a get-rich-quick solution to other problems they have created in their lives. Any person who is giving up or quitting in their personal life hasn’t much chance of succeeding at gold mining! If you are not finding enough gold, you cannot blame the claim, the river, the club you belong to, or anything else.

Vein deposits include most gold mines, many large silver mines and a few copper and lead-zinc mines.. Many outcrops of good looking veins are barren of gold or other ore minerals, but rich ore shoots may occur unexposed on surface, either down dip or along strike. Therefore, geochemical pathfinders are required. These include arsenic
