This fault is defined approximately by the limits of the dacitic intrusive that in part host the copper-gold-silver-molybdenum mineralization of the Emigrant District. Subsequent ground preparation events produced the fracture systems and breccia pipe structures that became the loci for later mineralizing fluids that formed the breccia-pipe-hosted mineral deposit of the district. Analysis of the work completed to date indicates that ten highly mineralized breccia-pipes are part of the same mineralization event and are zoned from a molybdenum rich core through copper gold to copper silver on the outer edges of the central area. is focused on the exploration and development of several targets within a fifteen square kilometer (six square mile) area, located in the core of the mineralized and intensely altered Emigrant Mining District, South-central Montana.As many as ten highly mineralized breccia-pipes and two porphyry targets exist within the property boundary and have been variously explored by historical drilling including 12,874 meters (42,237 feet) in 83 holes, induced polarization geophysical surveys, rock chip sampling and geologic and alteration mapping.
The Emigrant Stock is intrusive into these dacitic volcanics, forms the core of the Emigrant District and is also the center for alteration and mineralization.This mountain building event also resulted in the emplacement of early Tertiary intrusive stocks and the extrusion of voluminous volcanic rock sequences of the Absaroka-Gallatin volcanic field along reactivated structural zones of Precambrian crustal weakness.Five historic mining districts, including the Emigrant District, are geologically and genetically related to these intrusive centers.The House bill would push back the capital provision's enactment date to March 31, 2010, by which point Emigrant had fallen below the billion mark.So a more honest title for the legislation would be: "A bill to prevent Emigrant Bank from losing 0 million in Tier 1 capital."To be sure, there is a reasonable argument in favor of changing the law for the benefit of Emigrant.
