菱刈金矿位于九州鹿儿岛市以北约85公里,海拔265米。该地区火山活动频繁。鹿儿岛地区早在十七世纪中叶就开始采金。住友金属采矿公司于1968年开始勘探,1983年公布该矿矿石储量为150万吨,金品位为80克/吨。矿山于1982年开始掘进一条斜坡道,1985年7月穿入矿体,头三个月的矿石平均品位达162克/吨。矿石品位随深度的增加而逐渐下降,海拔标高-10米(斜坡道口以下 Ling Kari gold mine is located about 85 kilometers north of Kagoshima City, Kyushu, 265 meters above sea level. Volcanic activity is frequent in the area. Kagoshima started gold mining as early as the mid-seventeenth century. Sumitomo Metal Mining began exploration in 1968 and announced in 1983 that it had 1.5 million tonnes of ore and a gold grade of 80 g / t. The mines started to ramp up a ramp in 1982 and penetrated into the ore body in July 1985 with an average ore grade of 162 g / t in the first three months. Ore grade decreases with increasing depth, elevation elevation of 10 meters (below the ramp
