Other gold deposits were found in Montana resulting in considerable production and the geology of the state indicates that there are many other deposits that remain to be discovered. Several have already been identified. Finding gold requires good geological detective work. The US Geological Survey ranked Montana as number 7 in gold production in the US and reported that the state included 3.

Bergendahl and Koshmann, 1. Based on geology, it is predictable that several large undeveloped and undiscovered gold deposits will be found, identified and developed in the future. Rocks And Diamonds Levels' title='Rocks And Diamonds Levels' />The principal placer districts are in the southwestern part of the State. The most productive placer deposit was Alder Gulch near Virginia City in Madison County. Ps2 Games With Elf Binaries. Other important localities are on the Missouri River in the Helena mining district. The famous Last Chance Gulch is the site of the city of Helena. There are many districts farther south on the headwaters and tributaries of the Missouri River, especially in Madison County which ranks third in total gold production in the State. Gold was produced at many places on the headwaters of the Clark Fork of the Columbia River, particularly in the vicinity of Butte. Placer production from the Butte district, however, has been over shadowed by the total output of byproduct gold recovered from the mining of lode deposits of copper, lead, and zinc. Bannack district. Following discovery of significant gold in the streams within the Bannack district in 1. Grasshopper Creek and several tributaries at the southern end of the Pioneer Range. Mining included placer, hydraulic and some lode activity during the period of 1. Grasshopper Creek from 1. More than 1. 32,0. Rocks And Diamonds Levels' title='Rocks And Diamonds Levels' />At todays gold price, this district produced more than 1. The geology of Bannack was described by Winchell 1. Paleozoic Madison Limestone. Immediately above the Madison are remnants of the Quadrant Quartzite. These sedimentary rocks were intruded by granodiorite that is nearly circular in plan on the south side of Grasshopper Creek. A minor granodiorite intrusion is also found on the north side of the creek to west of Bannack. The eastern portion of the district is overlain by Tertiary volcanics. Lode deposits are interpreted contact replacement mineralization with some fissure veins. The ores are dominantly gold with some silver, lead and copper and generally found along the contact between the limestone and granodiorite, or in stringers or small fissures. Large amounts of garnet, with some epidote, are also along the contact. One of the principal lode deposits, the Golden Leaf group included the Golden Leaf, Priscilla, Hillside Placer, Wadams, Wallace, French, and Excelsior mines. The underground workings were ultimately integrated through an extensive network of more than 1. Dunn, Priscilla, Golden Leaf, and Thompson lodes. The Golden Leaf group produced 2,5. Based on the type of mineralization, this area is ripe for additional discoveries. Such replacement deposits are typically erratic and follow zones of brecciation exploration geophysics around the granodiorite plugs and a search for additional plugs could be productive. Alder Gulch Virginia City. The Grasshopper Creek gold rush led to other discoveries in Montana including rich placers at Alder Gulch Google. Earth coordinates 4. N 1. 12o. 053. 8W near Nevada and Virginia cities about 4. Bannack in 1. 86. Placers at Alder Gulch were mined upstream for 8 to 1. This was the richest placer operation in the world at its time of discovery. At one point, 4 dredges operated in this gulch. In three years, 3. Up until the 1. 93. As prospectors worked their way upstream, the gold became coarse and lodes were found near Summit Mountain to the southeast. Gold was later mined at Oro Cache, Kearsarge, Keystone, Atlas and the Bartlett mines. Sizable nuggets were recovered from the district. In 1. 90. 2, the New York Times reported a 4. California Gulch this followed the recovery of an 8. These nuggets support that a major undiscovered lode or ore shoot is found in the immediate area potentially under the gulch. The district is underlain by Archean gneiss interbedded with iron formation, marble, graphitic schist and amphibolite intruded by pegmatite and ultramafic dikes. Gold was found in place in northeast trending shear zones associated with pyritiferous veins and breccias that exhibited both sericitic and potassic alteration. Exploration by Kennecott resulted in discovery of a 1. Apex Kearsarge property. At the nearby Atlas property, Anaconda identified 3 to 5 foot wide vein with a 2,0. This vein averaged 0. Au and 0. 3 opt Ag with a minimum resource of 5. The nearby Oro Cache mine produced gold from 1. This vein contains gold in quartz ankerite pyrite breccia and stockworks in potassically altered gneiss. Surface samples yielded an average grade of 0. Au. Alder Gulch along the Ruby River has headwaters a short distance upstream from Virginia City. Based on the amount of gold found in lodes in this district, it is likely that other deposits remain to be discovered. The identified lodes do not account for the amount of gold found in the placers. And the presence of 2 million ounces in resources identified by Kennecott and Anaconda in this district should make this area very attractive for future exploration. Based on current gold prices, this district produced gold worth about 5. With detailed geological mapping, other deposits will be found in this district. During regional examination of this district, I was able to identify some cryptovolcanic structures in this region. Can you find these Are they diamondiferous kimberlitesDiamondiferous kimberlites, numerous lamproites and lamprophyres and some detrital diamonds have been found in this craton Hausel, 1. Confederate Gulch. Nearly 9. 0 miles to the north northeast of Alder Gulch is Confederate Gulch coordinates 4. N 1. 11o. 243. 7W. This gulch contained some of the richest placer ground in Montana and lies on the western slope of the Big Belt Mountains between Helena and Townsend east of the Missouri River. A rush followed the discovery of gold in 1. During the boom, miners worked placer claims on the upper stretch of Confederate Gulch and its tributaries, especially at Boulder Creek, Montana Gulch and Cement Gulch. The district continued to produce gold from both lode and dredge operations, at least into the late 1. Malone et al. 1. 99. Wolle 1. 96. 3 Lyden 1. The principal rocks underlying Confederate Gulch are sedimentary, including shales of the Spokane and Greyson formations and limestones of the Newland Formation. These are cut by diorite and quartz diorite dikes, stocks and sills. Narrow quartz veins along fractures in the diorite and along bedding planes in the shale contain high grade gold. Ore values decreased at depth in the lode mines, and few were developed deeper than 1. In addition to the quartz veins in shales, the diorite contains low grade mineralized shears Sahinen 1. Pardee and Schrader 1. Reed 1. 95. 1. The decrease in gold at shallow depth is puzzling and likely due to supergene enrichment.
