20.66 Acre Lode Claim – Rochester District – Madison County, Montana

Montana Gold And Silver Mines is proud to present the Historic Gold Nugget Mine Mine Unpatented Lode Mining Claim for sale. This is a 20.66 acre unpatented lode mining claim for sale exclusively through Montana Gold And Silver Mines. The claim is located just outside of Twin Bridges, Montana and has been properly staked and marked. All Montana Gold And Silver Mines claims have been carefully surveyed, mapped and researched. Field work is completed by our own experienced, well educated Mine Survey Team.

Remote Montana gold mine. The heart of the Rochester Mining District has a long and detailed history. The Gold Nugget Mine Mine is in a quiet area in the historic Rochester mining district. The ores show substantial amounts of native gold (common in the area), iron, copper, quartz and pyrites. The mine dumps could most likely be processed at a very good profit.

The shaft would need to be rehabilitated but a few days work could get it secure and you to the high grade ore body.

Remnants and items seen in the area indicate there has been work done after 1950. It is estimated by the surveyors that the claim has been worked intermittently in the 1900’s.

There is direct BLM road access to this claim and room for staging, parking and other operations.

The Bureau of Mines has estimated that demonstrated U.S. reserves of gold are 85 million ounces. Approximately one-half of the total resources are estimated to be by-product gold, while 40% of the remaining one-half (56 million ounces) could be mined for gold alone … Most U.S. gold resources are in the nation’s western states. About 80% of the U.S. gold resources are estimated to be in Alaska, California, Idaho, Montana and Washington. Nearly 75% of all resources are estimated to occur in lode deposits.

History of the Mines


Montana is ranked 7th by the USGS for total gold production in the US and has 31 mining districts. Gold production for the 1800’s to 1968 is 17.8 million ounces and large amounts of gold have been mined from 1968 to present. Geologists have predicted that based on the past and the geology of Montana that several large gold and silver deposits will be found and developed in the future.


The Gold Nugget Mine Mine Mine is located in the northeast quarter of section 32. It is about half a mile northeast of Rochester.

Rocks in this district are dominantly schist and gneiss that are locally intruded by small plutons of quartz monzonite, diorite, and aplite related to the Boulder batholith. Ore deposits are mostly northeast-trending veins in gneiss and schist; they contain gold, silver, arsenopyrite, pyrite, and lesser amounts of lead, zinc, and copper minerals in a quartz gangue. Much of the ore has been oxidized to a depth of 600 feet and consists of quartz, limonite, and oxidized copper and lead minerals.

Rochester District Information

The Rochester or Rabbit mining district was discovered in the 1860s when outcroppings of rich, oxidized gold ores were found on Watseca Hill on the south slopes of the Highland Mountains northwest of Twin Bridges. By 1869, eight hundred men lived in tents and log cabins on the surrounding hills. The Watseca lode, which was discovered in the 1860s, was the key to the region. The region was too dry for successful placer mining. Several arrastras such as the White’s and the Ward’s along with stamp mills such as the Rochester mill and the Allen mill successfully reduced the gold ore. A ten-stamp mill, built in 1868 at a cost of $34,000, cleaned up $15,286 in gold in nine weeks.
The passage of the 1872 mining laws gave lode mining a shot in the arm by revising antiquated claim laws based on placer mining. Lode mining was revived in the district in 1873 with the successful operation of the Day, Julia Homes, Pavcippa, and Watseca mines. By 1880, mining was back in full swing with many new claims operating. By 1896, F.R. Merk owned the Watseca mine, the largest property continuously operating within the district. Through lessees, free-milling gold averaging $30-75 at ton was recovered. The Buffalo mine, which adjoined the Watseca, was also extensively developed. Although gold was the prevailing deposit in the area, lead and small amounts of copper were also found. To treat these varied ores, concentrators and small lead smelters were built in or near the town.
The period of greatest activity was from 1898 to 1905 when the Watseca was in full production. The district produced gold ore valued at several million dollars , as well as appreciable amounts of lead and silver. At this time the population of the town of Rochester reported rose to 5,000. Stamp mills, chlorination mills, and other types of concentrators, as well as lead smelters were built in the district. The increased cost of labor and materials cut production profits to such an extent that by 1906, only eight mines continued to operate. Owners began to sell off their properties or to abandon them. By 1907 the district was almost deserted and remained so until 1926. A brief three year boom resulted from production on the Emma, Colusa, and Jack Rabbit claims, as lead-silver properties. A mill, erected at the Emma mine by the Butte Madison Mines Corporation, ran until 1932. Since then the district has lain dormant.
Geologically, the district is composed of fine grained gneisses and mica and hornblende schists of Archean age. Sills and dikes of aplitic granite have been intruded roughly parallel to the banding in the metamorphic rocks which in general trend northeast and dip 15-40 degrees to the northwest. Stocks of diorite and andesite flows are also present in the area east of Rochester. Basalt flows occur to the west. The main body of the Boulder batholith is exposed a few miles to the north and the igneous bodies of Rochester may be upward reaching fingers of the main bodies which may underlie the whole region.
The ore deposits are in well defined veins which usually strike north or northeast and dip steeply to the west. The veins are associated with the granite dikes. They are commonly narrow but locally very rich. A few veins are wide and of low grade. Most veins are valued chiefly for their gold content but some are silver-lead veins. The ore minerals include: native gold, argentiferous galena, cerussite, malachite, chrysocolla, pyrite in a gangue of quartz. Vanadinite and exdemite have also been reported.
Although statistics are not available for the early years, it has been estimated that the district produced $2 million from 1868 to 1904. From 1904 to 1912 the district produced 10,314 tons of ore that was reduced to 4,893.1 ounces of gold worth $101,149; 24,923 ounces of silver worth $15,496; 1,913 pounds of copper worth $321; and 382,086 pounds of lead worth $17,685. Total value of the ores during this period was $134,651. Prior to 1932 the district was credited with a total production of 2.5 million.
