Gold-Ore Resource Assessment Of Zhulazhaga Gold Deposit In Inner Mongolia

The Zhulazhaga was found out in the prospect area of Alashan the Inner Mongolia which is the largest and unique gold deposit. Layer bound characteristic of the mineral ore controlled by stratum and lithology being obvious. It's very important for searching mineral additionally in the northern of Inner Mongolia.On the basis of collecting and using the known data of the mining area, we do the deep drilling verification and identify the attitude, distribution, class, mineralization characteristic and type of the mineral ore preliminarily. The purpose of the work is that augmenting resources quantity of the known deposit and summarizing regional metallogeny rules through the spot deepened dissection and the comprehensive study of areal quality, then evaluat the potential of regional mineral resources. Because the comprehensive geophysical survey through the aligement is abnormal, we get the following stand point through studying the principle of control mineralization, analysing distributing rules of mineral ore and geological characteristic of the deposit.1. The Wulanneihasha-Zhulazhagamaodao-Hubuhete, whose mineral-formation geological condition and principle of control mineralization are similar to the ones of the Zhuzhalaga gold deposit, is the most potential zone to find the same and large or tremendous deposit.2. The study on hydrothermal alteration of host rocks are focus on antinolite, the mineralization of chlorite, sericite, silica, antinolite, tremolite can attribute into hydrotheramal alteration, which is associated with minralization of gold.3. Analyzing characteristics of magnetic anomaly and IP anomaly, according to which, combined geophysical anomaly of working area can classified into three parts.4. Most gold is situated in the gap between the grains of gangue minerals, few grains are fixed in ore-bearing minerals (limonite, pyrrhotite) or around it, which is different from that situated in sulfide and pyrite of common gold deposits.5. Feasibility study on Zhulazhaga gold mine have involved in occurrence of orebody, distribution, grade, characteristics of mineralization and value of application.
