The Haujiahe deposit in the Mouding Copper Mine is a Mesozoic lacustrine sedimentary sandstone copper-bearing deposit. The main ore body of No. Ⅲ-1 is inclined at 17-23 °, with a thickness of 1.0-17.5 meters (averagely 7 meters) and a length of 150-450 meters 284 m) with an extension of 2800 m. The feldspars quartz feldspar f = 10-12, grade 0.94-2.56% (average 1.23%). The top plate is light-colored feldspar quartz sandstone f = 10-14 and the chassis is purple Feldspar quartz sandstone f = 8 ~ 10, stable ore rock stability.Crop plate exposed area of 1400 ~ 2700 m ~ 2, during the one-year exposure period
