發(fā)現(xiàn)銀礦的區(qū)域位于河南省小秦嶺南部，行政區(qū)隸屬于靈寶市朱陽(yáng)鎮(zhèn)，面積約22平方公里，處于華北克拉通南緣成礦帶，構(gòu)造演化復(fù)雜、巖漿活動(dòng)頻繁，成礦條件優(yōu)越，優(yōu)勢(shì)金屬礦產(chǎn)有金、鉬、鉛、鋅、銀等。位于此地的小秦嶺金礦田為我國(guó)第二大黃金生產(chǎn)基地。經(jīng)過(guò)30多年的開(kāi)采和利用，已面臨資源枯竭的局面。為挽救這一“危機(jī)礦山”，從2010年起國(guó)土資源部、河南省政府決定加強(qiáng)小秦嶺區(qū)域深部及外圍地質(zhì)找礦工作，在此過(guò)程中發(fā)現(xiàn)上述大型銀礦。
此前，河南省已擁有我國(guó)最大的銀礦，即桐柏銀礦，位于南陽(yáng)市桐柏縣朱莊鄉(xiāng)，已探明C+D級(jí)銀金屬量2661.5噸，為中國(guó)四大銀礦之首。
