邦德国际黄金有限公司所属的里士满希尔金矿已于1988年12月的第一周投产。该矿位于美国南达科他州的利得附近,系一座露天开采的堆浸矿山,预计黄金年产量大约为1337.45公斤。该矿现有的估计储量为3538万吨,金的位品是1.65克/吨,采矿生产的边界品位确定为0.47克/吨。 随着相邻区域矿源的增加,预计矿山现有的4年服务年限可以延长。在近矿区域内,正在进行的勘探工作包括碳酸岩分析,这是勘探的初级阶段,还有矿床的验证工作,这是勘探的可行性阶段。 The Richmond Hill Gold Mine owned by Bond International Gold Ltd. was put into operation in the first week of December 1988. Located near Leet in South Dakota, USA, the mine is an open-pit heap leach that is estimated to produce about 1337.45 kilograms of gold a year. The mine currently has an estimated reserve of 35.38 million tonnes, a gold unit of 1.65 g / t, and a border grade of 0.47 g / t for mining production. With the increase of mineral resources in adjacent areas, it is expected that the mine’s existing 4-year service life can be extended. In the near-mine area, ongoing exploration work includes carbonatite analysis, which is the primary exploration phase and the verification of the deposit, which is a viable stage for exploration.
