曹家坝矿区位于湖南新邵县北东35公里。地表原见铁锰矿,仅有数处孤立露头,每个露头面积数平方米至百余平方米不等。1958年大炼钢铁及其前后曾经开采。1971年省地质局四六八队曾经检查评价,认为属风化淋滤型锰矿床,富矿采空,埋藏矿石不多,无进一步工作之必要。但在存在问题中指出:岩矿鉴定有石英石榴子岩,光谱分析Sn、W、Cu、Pb等金属元素含量稍高。1973年在1:20万涟源幅区调时,省局区调队六分队曾在矿区西侧溪流重砂中有六个样品含白钨矿,圈了一个白钨矿异常区;对铁锰矿石拣块样化验,其中W、Bi、As、Cu、Pb、Zn等金属元素含量偏高,但未进一步工作。
Caojiaba mine is located in Xinshao County, Hunan Province, 35 kilometers north east of Shaodao County. The original manganese iron ore surface, only a few isolated outcrops, each outcrop area of several square meters to hundreds of square meters. In 1958 steelmaking and its mining have been around. In 1971, the Provincial Bureau of Geology Brigade had checked and evaluated that it belongs to the weathered leaching-type manganese deposit, which is empty of mined ore and has few burial ores, so it is not necessary for further work. However, in the existing problems, it is pointed out that quartz and pumiceite are identified in rock and mine, and the contents of Sn, W, Cu and Pb are slightly higher than those of other metal elements. In 1973, 1: 220,000 Lianyuan amplitude region tune, the Provincial Department of Regulated Force Sixth Brigade had in the west side of the stream of heavy sand in six samples containing scheelite, surrounded by an area of scheelite anomaly; iron Manganese ore sorting block test, in which W, Bi, As, Cu, Pb, Zn and other metal elements were high, but did not work further.
