Historic Blackman Gold Mine – 20 acre Lode Mining Claim for Sale – Twin Bridges, Montana


The Blackman Mine is a very unassuming site at first glance. At the uppermost section of the claim, there are some small prospects. These prospects lead down to some larger workings that were likely a series of adits and shafts. The ores show native gold deposits, some showing on quartz, others in a granodiorite type of hard rock. Both lend well to crushing and separating. Production would be expected at .75-1 OPT Gold. Under casual use an operator could expect to process 1-2 tons per week. If larger deposits are located, it would require some road repair to ship larger amounts of ore down the hill.

Historic Blackman Gold Mine and Camp

20 Acre Lode Claim – Silver Star District – Madison County, MT

Aerial view of claim and boundaries.

Overview of the Claim

This is a third party sale and is not eligible for financing.

Gold Rush Expeditions, Inc. is proud to present the Historic Blackman Gold Mining Claim. This is a 20 acre lode mining claim for sale exclusively through Gold Rush Expeditions, Inc. The claim is located just outside of Twin Bridges, Montana and has been properly staked and marked at all corners. All Gold Rush Expeditions, Inc. claims have been meticulously surveyed, mapped and researched. Field work is completed by our own experienced, well versed Mine Survey Team.

The Blackman Mine is a very unassuming site at first glance. The claim sits in a very remote area of the district and is rarely visited. Small prospects dot the uppermost section of the claim. These prospects lead down to some larger workings that were likely a series of adits and shafts. Time has been unkind and there is significant overburden and dirt that has started to fill the mines at this level. An old miners shack at the edge of the gulch seems to be the end of the workings. As the mine works its way down the gulch, the main workings of the claim begin to emerge. A large adit entrance, once fully timbered, is still visible today. There is wide, thick track protruding from one of the adits, mostly covered with sage and grasses. The amount of overgrowth on the claim is a testament to how long its been since anyone has visited. The adit is in relatively good shape but needs some clearing and shoring to be completely safe.

The ores show native gold deposits, some showing on quartz, others in a granodiorite type of hard rock. Both lend well to crushing and separating.

Access to the mine is limited to 4WD only. Modified 4WD is recommended for clearance and some tight road sections. Once at the claim, there is limited room for parking. Likely only 2-3 vehicles will be able to park at one time.  The area is mostly devoid of natural resources. There is some non-potable water inside the mine that could be utilized for tasks. No timber or wood is available on the claim.

This site would lend itself well to a small, casual use operation. Production would be expected at .75-1 OPT Gold. Under casual use, an operator could expect to process 1-2 tons per week. If larger deposits are located, it would require some road repair to ship larger amounts of ore down the hill.

Overview of the Mines

The Blackman Mine was originally owned by George Blackman as well as can be determined. The mines are a series of cuts and adits along a general trend running down the hillside. The main ores seen are gold in quartz and some silver and likely lead. The lower most workings are hidden and difficult to locate. This has kept the mine and ores relatively untouched. A drift cut on a hanging wall drives into the mountain for an estimated 150′, it is assumed that these workings intersect the shafts and declines above. All of the workings are cut for gold production and  silver and lead ores have been largely discarded. There are 2 good veins of gold ore visible in the lower drift. These veins run back into the mountain as well. There is a small collapse 30′ into the mine that should be cleared before further exploration can be completed. This is mostly in the form of one large rock that has come down.

Air is good throughout the mine and stays constant at 20.8% with no abnormal CO2 or LEL gases detected.


Newly weds and pioneers, George and Augusta Blackman decided to take their honeymoon to Virginia City, Montana in hopes to establish gold mines. Over the years they claimed numerous mines, including this particular claim in 1889. Due to the nature of the west’s instability of law and order, George would live by his mines to keep it guarded, even during the grueling winters. During that time, Augusta established a boarding house for miners to stay. George lived his final years in Silver Star where he got to witness Montana achieve statehood before he passed away in 1892. Augusta journaled these adventures and even got to see her work get printed before she died in 1914

[learn_more caption=”Surveyor’s Observations”]
The upper workings at the claim are interesting in that they show some gold ores in selected areas. There is a lot of collapse and overburden that has filled in the adits and shafts and will need to be dug out to accurately assess the source of the gold. Contrarily, the lower adit on the claim shows very good deposits of gold ore and visible gold, this running in two veins inside the mine that is nearly hidden to the casual passerby. The lower adit also needs to be cleared but shows that it likely connects to the rest of the workings on the claim. Native gold will be the primary element of interest on the claim. There is some silver and lead but not in any appreciable quantities seen during the survey.

Silver Star Mining District Information


Silver Star, the third oldest town in Montana, was founded in 1866 by a prospector by the name of Greene Campbell. While prospecting in the hills west of the Jefferson River, he discovered an out crop of gold at the side of a hill. He named this initial claim after himself. Afterwards, he started to employ workers to help build his business. News of the newly discovered gold began to circulate, and families began to move into the district.  Between 1867-68 the first log cabin was built in the district. Many of the early settlers were transients trying to find prospects. They wanted to make sure they were near a water source, so they constructed cabins near Cherry Creek and the Jefferson River. By 1873 a hot spring was piped into the district and the population began to grow to 2000 inhabitants with hundreds of workers. Since the decline of the mining operations, the population has decreased significantly to less than 200 people today.

The Silver Star mining district is northwest of the town of Silver Star, about 25 miles airline southeast of Butte, in the northern part of Madison County. The geology and ore deposits of the district have been described by Winchell (1914, p. 139-144). The rocks exposed in this district are Tertiary granite, Cambrian ( ?) limestone, and Precambrian schist, slate, and quartzite. The limestone is metamorphosed and replaced by garnet, epidote, magnetite, and pyrrhotite at its contact with granite. Gold, silver, copper, and lead occur in tactite deposits and a quartz vein. The Broadway mine, about 2 miles northwest of Silver Star, is on a tactite zone in the Cambrian limestone near the granite contact. A small glory hole exposes a U Shaped sulfide ore body composed mainly of gold-bearing pyrrhotite surrounded by tactite and hornfels containing magnetite, garnet, and epidote. The tactite zone extends northeast from the glory hole for about 700 feet, through two smaller opencuts, and southwest for about 500 feet. Ore deposition appears to have been controlled by a northeast-trending fault that approximately parallels the limestone-granite contact.

This claim and property come with the full backing of Gold Rush Expeditions and our legal resources. We take mining rights seriously. Hopefully you will never have any problems with the Forest Service or BLM employees, but if you ever do you can rest assured that we will fight to protect your mining rights. We have a lawyer on retainer and offer free no-cost legal representation. We are here for you long after you buy a claim from us.

As usual, we recommend that you file a Notice of Intent with the BLM or local Forest Service office before working your claim. This doesn’t cost anything as long as you are operating under casual use. We would like to see that everything goes according to your plans. Some activities may require permitting with the local Forest Service or BLM offices. We have created a page on our website with helpful information on writing a Notice of Intent and, also if you are unsure about what activities are permitted under casual use, we’ve got some helpful links at the bottom of that page.

“The most important piece of your mining claim is that actual mining claim documentation and location. While other fly by night operations may have the best of intentions, they often get it wrong. This results in you, as a customer, not getting what you paid for. GRE has been documenting, writing and transferring mining claims for over 10 years. We know what we are doing. From our in-house notaries to our master land surveyors, we get the job done right, and we back it up in writing. GRE Guarantees that this mining claim has been written correctly and accurately. It has been physically staked on all corners with GPS embedded images for clear verification. GRE will provide documentary evidence of all paperwork and location staking for the claimant.

GRE works hard to make sure that everything we do is perfect, but occasionally we may make a mistake. So while it is understood by the Customer and GRE, that all attempts have been made to verify accuracy and location in relation to this claim, we want to go one step farther. In the case of inaccuracies or other issues that may impact your claim, GRE will amend or modify and record any documents and physical monuments as deemed necessary at no cost to the buyer.

GRE guarantees this mining claim to be exactly as described and pictured. Please view all images and read complete claim description. We spend a lot of time and effort to document all aspects of each mining claim.

This Guarantee is not any sort of guarantee of mineral content, reserves or future earnings. Assay reports, Reserves, and mineral values are provided as they have been recorded by United States Geological Surveys, and state and local mining reports. Historical records and production are provided for information only. GRE strongly advises all potential claim owners to educate themselves about mining claims. Please be fully aware of what is conveyed with this mineral claim. If you have questions about mining, mining law, processing or even other properties, please contact us; our offices are open from 9am to 5pm MST, Monday through Friday. We are here to help the small miner work and support the development of mining in this new era of Mining in America.

It’s hard to make an accurate assessment of mines and mining claims today. The history, the books and the documents change over time. Universities and Agencies seem to write and release documentation designed to deter the average miner.

We examine each mine, and determine its actual potential. This is based on documented and verifiable history, as well as field observations and mapping of the sites. This helps us thoroughly and accurately describe our claims, as well as help you make informed decisions regarding the purchasing of a mining claim. In addition, the geological and historical information provided gives claim owners the tools to know where to look. After all, the gold, precious metals and minerals are out there, and there is a lot of it, you just have to know where to look. If you need more information, please feel free to contact our office and set an appointment to discuss your desired property.

Legal Notes:

*This claim is not for any Speleothems, Stalactites or Stalagmites. This claim is not for any cave formations of any sort. *This claim is not for ownership of a cave or any sort of cave related items. It is for control of locatable minerals and the ability to secure the land on which your minerals are located. *This claim is for Mining Claims. Mining Claims are administered by the BLM. They are not administered, nor are they under any control by the US Securities and Exchange Commission. *This sale does not constitute any sale of stocks or other security interests that represent a current investment ownership interest in an entity. Nor does this sale represent any effort by individuals to raise money or find investors for Businesses. A mining claim is not ownership of the land. It is full control of locatable minerals. The BLM defines located minerals as: * Locatable minerals include both metallic minerals (gold, silver, lead, copper, zinc, nickel, etc.) and nonmetallic minerals (fluorspar, calcite, mica, certain limestone and gypsum, tantalum, heavy minerals in placer form, and gemstones). (Edited from:
__AND_RESOURCE_PROTECTION_/energy.Par.26680.File.dat/MiningClaims.pdf) The General Mining Law of 1872, as amended, opened the public lands of the United States to mineral acquisition by the location and maintenance of mining claims. Mineral deposits subject to acquisition in this manner are generally referred to as “locatable minerals.” A lode claim is defined as: “Jefferson-Montana Copper Mines Co., 41 L.D. 321(1912), established the full test for a lode claim: “To constitute a valid discovery upon a lode claim, three elements are necessary: 1. There must be a vein or lode of quartz or other rock-in-place, 2. The quartz or other rock-in-place must carry gold or some other valuable mineral deposit, 3. The two preceding elements, when taken together, must be such that as to warrant a prudent man in the expenditure of his time and money in the effort to develop a valuable mine.” Additionally, Federal statute does not describe what constitutes a valuable mineral deposit; therefore the government has adopted the “prudent man rule.” This rule determines value based on whether or not a person will consider investing time and money to develop a potentially viable mineral deposit. This rule was first stated by the DOI in 1894, in the adjudication of Castle v. Womble, 19 L.D. 455 (1894), the holding of which states: “…where minerals have been found and the evidence is of such a character that a person of ordinary prudence would be justified in the further expenditure of his labor and means, with a reasonable prospect of success in developing a valuable mine, the requirements of the statute have been met.” Note, this is site is not subject to the Cave Protection act of 1988, as Federal Law states: 16 USC Sec. 3378&01/08/2008 Sec. 3378. Miscellaneous provisions -STATUTE- (d) Existing rights Nothing in this chapter shall be deemed to affect the full operation of the mining and mineral leasing laws of the United States, or otherwise affect valid existing rights. -SOURCE-(Pub. L. 100-691, Sec. 9, Nov. 18, 1988, 102 Stat. 4550.) REFERENCES IN TEXT The mining laws and mineral leasing laws of the United States, referred to in sub sec. (d), are classified generally to Title 30, Mineral Lands and Mining. The information above is cited from the official Department of the Interior Bureau of Land Management page.
