陕西银母寺铅锌矿床深部东延找矿进展与启示

银母寺铅锌矿是上世纪八十年代勘查探明的一个高品位(平均铅+锌品位大于10%)中型铅锌矿,其中的Ⅰ-4号主矿体以115°方向向东倾伏,倾伏角20°~30°,从银母寺铅锌矿向东到西河全长3500 m的范围内分布着四家采矿单位,其中三家都在采矿的过程中发现了Ⅰ-4号主矿体,截止目前主矿体已由原来的长度1000 m,增加到2000 m,资源储量相当于又增加了一个小型铅锌矿。矿体向东依然没有封闭的迹象,仍有很大的找矿空间。银母寺铅锌矿深部东延的发现和发展,揭示了凤太地区深部找矿仍有很大的空间,找矿的思路应从地上转向地下。

Development in Yinmusi Eastward Extension Deepened Prospecting for Pb-zn Deposit

The Yinmusi lead-zinc deposit was surveyed and proven to be a high grade medium lead-zinc deposit minein the 1980s, with average lead +zinc grade of more than 10%) , The main ore bodies from No .1 to 4 plung towards east at 115° with pitching angle of 20°to 30°.Within the scope of a total length of 3500m from east of Yinmusi to the Sihe , distributed four mining organizations , three of which have found the 1-4 main orebody in the mining process .So far the main ore body has been extended from the original length of 1000 meters, up to 2000 meters, and reserves were added by that of a small lead-zinc mine.Signs of ore body enclosure is still unforeseen , so there are still a lot of space for mineral prospecting .The discovery and development of deep eastward extension of Yinmusi lead -zinc deposit reveals that great prospecting potential exists in the deep prospecting in Fengtai region .
