白马寨镍矿位于金平县城西北，发现于1957年，1960年正式转入勘探，1965年提交了储量报告。该矿床是个中型镍矿，保有镍储量5.32万t，镍品位1.23%。含矿岩体侵入于下奥陶统第三四组地层中。岩体呈向北西倾伏的扁柱体，倾伏延伸大于600m，宽190m，厚47m。岩体由辉长岩、辉石岩、橄榄岩组成，并依次由外向内呈环带状分布。不同岩相之间呈突变接触。矿床为一复合矿体，呈扁柱状产于含矿岩体的中部(下图)，其体积约占整个岩体的1/3。形态、产状与岩体一致。矿体由稀疏浸染状、海绵晶铁状和致密块状三种矿石组成。白马寨镍矿矿石的特点是含银、铟高，尤其在块状矿石内，并形成银镍黄铁矿和银金矿。矿床地质特征表明，含矿岩浆，乃至矿浆沿同一构造裂隙多次上侵形成的，贯入作用属脉冲式活动，故称其为岩浆深部熔离-脉冲式贯入矿床。

Located in the northwest of the city of Jinping Baimazhai Nickel ore, discovered in 1957, 1960 officially transferred to the exploration, 1965 submitted reserves report. The deposit is a medium sized nickel, nickel reserves have 53 thousand and 200 t, nickel grade 1.23%. Ore bearing intrusion in the lower Ordovician formation in the three or four groups. The rock mass is a flat column in the west to the north, and the bend is larger than 600m, and the width is 190m, and the thickness is 47m. Rock composed of gabbro, pyroxenite and peridotite, which in turn is zonal distribution from outside to inside. Mutation contact between different lithofacies. The ore deposit is a compound ore body, which is in the middle of the ore bearing rock (below), which is about 1/3 of the whole body. Form, production and consistent. The ore body is composed of three kinds of ore, which are sparse disseminated, spongy crystal and dense block. The characteristics of Baimazhai Nickel minerals containing silver and indium is high, especially in the massive ores, and the formation of silver nickel pyrite and silver gold deposit. Show that the geological characteristics, ore magma and ore pulp, along the same tectonic fissures repeatedly invaded formation, penetration effect is pulse, so it was the deep magmatic liquation pulsed penetration deposit.
