Niukutou concealed iron polymetallic deposit is a large scale skarn-type deposit, The main strat um is the carbonate rock of the upper Carboniferous Shijiaoyanggou formation and the intrusive rocks are the Indosinian monzogranite in this deposit. The deposit mainly occurs in the vicinity of the outer contact zone between the two. Mine exploration work began in 1969, which mainly focused on the smaller sporadic iron-polymetallic ore body near-surface. The previous exploration work has been little progress in prospecting due to lacking systematically recognizing the mining geological characters. Until the year of 2006, we made significant breakthroughs in prospecting on the basis of comprehensive analysis of geophysical characteristics, metallogenic theory of skarn deposits, and successfully geophysical prospecting methods for concealed ore forecast.
