史料考证与找矿(之三)：铜矿

云南铜矿是历史上开发最早的地区之一,至今已知的大－中型矿区（除边远的羊拉、托顶之外）,历史上几乎都不同程度地被开采过。也有历史上曾采冶辉煌,但至今却没有铜矿产出,找铜工作者也不知道的“古老铜矿”,俞元（澄江）铜矿即是一例。研究、考证采铜史料,认为澄江铜矿、东川茂麓厂、寻甸铜矿、永平宁台厂等,应列为新世纪重新评价的找铜目标。

TEXTUAL RESEARCH ON HISTORICAL DATA AND ORE PROSPECTING (PART 3),CU

Yunnan is one of the areas with the earliest Cu exploitation history.Except the remote Yangla and Tuoding,the large middle mines known so far were exploited more or less in history.However,there are a few "old Cu mines"with splendid exploitation and metallurgy history,which are not exploited for Cu production and known by Cu prospector today,such as the Yuyuan(Chengjiang)Cu deposit.According to the textual research on the historical data of Cu exploitation,the Chengjiang Cu deposit,Maoluchang of Dongchuan,Xundian Cu deposit and Ningtaichang of Yongping must be regarded as Cu prospecting targets for reexamination in the new century.
