peer agreement (net): +1hochgradig vererzte Goldlagerstätte Explanation: So würde ich das formulieren. High-grade bezieht sich auf den Goldgehalt des Erzes, Olafs Referenzeintrag enthält inhaltlich bereits alle Argumente, die ich (als Geologe mit einigen Jahren Erfahrung in der Goldexploration) hier anführen und belegen könnte. -------------------------------------------------- Note added at 1 Tag6 Stunden (2015-10-19 17:43:44 GMT) Post-grading -------------------------------------------------- Gerne & viel Erfolg! |

| Reference: high-grade gold mine Reference information: http://www.investopedia.com/ask/answers/022315/what-does-gra... What does the grade of a gold mine refer to? Gold mines and gold deposits are often categorized by the average proportion of gold contained in the ore at the site; this is also known as the ore grade. Higher-quality mines have higher ore grades, and lower-quality mines have lower grades. When gold ore has a high grade, it takes relatively less effort to extract an ounce of gold from the ground; less ore has to be dug out, which reduces input costs for the gold mining company. Another, less common definition of high grading refers to the concealment of precious metals ore by workers who have mined it. This definition had greater applicability and was used more frequently during the 19th century, when so-called high-graders would often hide gold ore in their lunch pails. To combat this problem, mining companies often required their employees to open their lunch pails, turn out their pockets and shower following their shifts. Understanding Precious Metals Grading All precious metals are graded by the proportion of metal in the ore. Grams per tonne, or g/t, is the most common metric used to represent the grade of an ore. The value of a precious metals mine is determined by its total estimated weight, the grade of the ore, and how difficult it is to extract and distribute. Precious metals are found in a wide range of geological sites. They show up in open pits, underground, under bodies of water and in single nuggets resting on the ground. Grading is usually only applied to open pits and underground deposits. The standards of high- or low-grade gold ore are set by the World Gold Council, which is a non-profit organization that was established to promote the use of gold and gold products internationally. In addition to marketing and supporting gold producers, the World Gold Council also researches gold mines and creates standards by which to evaluate gold mining prospects. The World Gold Council defines a high-quality underground mine as having a gold ore density between 8 and 10 g/t (grams per tonne), while a low-quality underground mine has a gold ore density of 1 to 4 g/t. Open-pit mines tend to have a lower grade, but they can be considered very valuable because of the lower average operating costs necessary to obtain them. The council recommends using cost per ounce, not gold ore grading, to evaluate a gold mine. Highest Grade Gold Mines in the World The highest-grade gold mine in the world, by far, is the Tua Tona mine in South Africa, according to 2013 data. With a gold ore density of 28 g/t, the Tua Tona has a 30% higher grade than the next-highest density mine, the Great Noligwa (also in South Africa). Of the 10 highest-grade gold mines, six are located in South Africa, including the top three: Tua Tona, Great Noligwa and Moab Khotsong. The Mponeng, a South African mine with the ninth-highest grade at 14.24 g/t, contains more estimated total gold than all of the other top-10 graded mines combined. All told, South African gold mines have the highest average grade, 6 g/t, of any country in the world. The next highest, Tanzania, only has an average ore grade of 2.84 g/t. |
