The Emigrant Creek Project contains several targets within a fifteen square kilometer area owned or controlled by Lucky Minerals. The project area is located in the center of a large core of highly mineralized and intensely altered geology known as the Emigrant Mining District, which is part of the Absaroka-Gallatin volcanic field that covers an area of 23,000 kilometers and is the largest Eocene volcanic field in North America, and follows a northwest trending pattern for over 250 kilometers from west-central Wyoming to Livingston, Montana.
Five Zones within the project area have been explored by various methods over the years and have been identified as highly desirable target areas for further exploration by the company. These target zones are known as St. Julien, DUV, Allison, Base Metal, and Emigrant Creek. 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.

The Emigrant Creek Project
Lucky Minerals Inc. 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 analysis of the work completed to date indicates these 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.
Emigrant Creek Mining Project
The Emigrant Mining District occurs along the western edge of the Absaroka Range of the Beartooth uplift, a northwest-trending fault-bounded structural block of Precambrian basement rock that creates the Beartooth Plateau physiographic province in the Middle-Rocky Mountains of south-central Montana. This Precambrian basement block comprises the deeper basement rock of the Emigrant Mining District. The Yellowstone River and the deep alluvial fill of the fault bounded Paradise Valley form the western margin of the Absaroka Range, Beartooth Uplift and the Emigrant Mining District. During Paleozoic and Mesozoic eras a thick sequence of marine and marginal marine sedimentary rocks were deposited in a shallow inland seaway that covered much of the area. During late Tertiary time, the region was uplifted to approximately the present altitude by the Larimide Orogeny. 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. These districts have been mapped over distances of at least 120 kilometers (75 miles) from northwestern Wyoming to south-central Montana along the northwest-trending Cooke City Structural zone, the most prominent of these Precambrian basement faults zones.
The Emigrant Mining District has been the site of small scale lode and placer operations since the 1870’s. During the period 1864 to 1935 an estimated 40,000 ounces of gold was produced dominantly from placer operations. The most recent phase of modern exploration started in 1990 when Kennecott drilled six helicopter supported core holes on the south flank of DUV Ridge. All of these holes intersected anomalous to ore grade gold and copper mineralization.

Emigrant Project Location Map
Project and Regional Geology
The Emigrant Mining District is centered on one of several intrusive centers localized on Cooke City Structural Zone at its intersection with the local Mill Creek fault. This intersection is the locus for the emplacement of the Emigrant Stock that is spatially, genetically and temporally related to the deposits of the district. The Lucky Minerals properties are underlain by Tertiary rocks of the Eocene (49-54 million years old) Absaroka-Gallatin volcanic field that consist of intermediate composition, calc-alkaline andesite and dacite rocks. Eruptive centers of several kinds are present including volcanic necks and plugs, intrusive breccia pipes, vent and caldera complexes and ring dike and cone complexes. 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. The stock is elongate northwest-southeast and is about 6.5 kilometers (4 miles) wide and 11 kilometers (7 miles) long. A bounding fault between the older andesites and the dacite porphyry intrusive Emigrant Stock appears to be localized along what is likely a collapsed and resurgent caldera complex. 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.
