Ore Grades Hi All
can someone comment regarding the grades at RG. Seems like they are good in reference to below and article
World Copper Resources A copper ore deposit is a localized zone in the earth’s crust that contains copper-bearing minerals in unusually large quantities. On average, the continental crust contains about 0.0058 percent copper, or 58 parts per million. A deposit of copper-bearing minerals is classed as an ore reserve if there are sufficient quantities and concentrations of minerals to be extracted at a profit. Commercial copper ore deposits today contain from 0.5 to 6 percent copper, or between 100 and 1000 times the crustal average. In contrast, iron and aluminum constitute around 5.8 percent and 8 percent of the earth’s crust, respectively, and their commercial deposits need to be only 3 to 10 times as concentrated as the crustal average. Thus, copper may be considered a relatively scarce element geochemically.<br /><br /> Read more at: <a href='https://www.miningequipments.org/faq/copper-resources-and-technology-in-mining-industry/'>https://www.miningequipments.org/faq/copper-resources-and-technology-in-mining-industry/</a><br />Copyright © BINQ
