Dayao, Ju Copper Deposit Creek - Shimenkan The Ore Block Metallogenic Prediction And Prospecting Program

Copper is a wide used and important metal, which is secondly to iron and aluminum. Because of the China's copper consumption, and supply shortages, the situation of long-term dependence on import is very difficultly change in the future. Copper consumption in China in 2002 for the first time the United States, has been the highest in the world for seven consecutive years. Domestic copper consumption in 2006 is up to 4,390,000 tons. Of which: domestic produced 1.43 million tons of copper (750,000 tons was produced, recycling 680,000 tons of waste copper), self-sufficiency rate of only 33%. Imported 2.96 million tons of copper (830,000 tons of refined copper, copper concentrate,1.13 million tons,1,000,000 tons of waste copper).Metal mines in China has been the exploitation of many decades or even centuries, proved reserves to maintain the verge of depletion of resources. Countries in 2005 to replace the national crisis resource exploration mining pilot screening a total of nine national pilot project, "Xiaohe-Shimenkan mineral resources of Luju Copper mine in Dayao county, Yunnan Province prospecting succeeding paragraph," is one of the pilot project, aiming to carry out the old deep mines and prospecting with the external current and long-term economic and social significance.The Chuxiong Basin is the main sandstone copper mineralization concentration area in China, and the Liuju copper deposit is one of the typical sandstone copper deposits in this basin. Based on features of regional geology, mine geology and deposit geology, the paper analyzes the datum of geological exploration and geological scientific research. Combined with the mining production and prospecting, and the results of the geochemistry applicing and the EH-4 measureing, it points out that the Xiaohe-Shimenkan ore block which located in the south and depth of Liuju copper deposit is the favorable segment for prospecting. The prospecting scheme of pitting and drilling is given in the paper. The inferred resources (333) and predicted resources (334) of total copper resource estimation are 0.15 million tons. It has important significance for enlarging the replacement resources, and metallogenic prognosis prospecting of the old mine in the depth portion and the periphery area.
