Historic Slim Sam

20 Acre Placer Claim – Park District – Broadwater County, Montana

The Historic Slim Sam Placer Mining Claim for sale, a 20 Acre Unpatented Placer Mining Claim. The claim is located just outside of Helena, Montana and has been properly marked. All claims have been carefully surveyed, mapped and researched. MT105766648

This is a remote Montana gold mine. Slim Sam Creek runs through the middle of the claim, provides plenty of year round water for all your mining needs. During surveying gold was easily found in the material by panning. The valley bottom is old river bed material. The higher benches also hold old river bed material. The claim boasts good access and does get visitors driving through on the road. The claim was originally surveyed and sampled for rich, free gold deposits in the gravels. There are plenty of areas to camp near this claim.

The creek bed is over 600 feet on this claim and there is water year round. It is likely there is some native silver, sapphires, and possibly some relics to be found on the claim but the primary commodity will be gold. Slim Sam Creek is known for it’s gold and there are multiple lode mines in the area that have been feeding good gold into the creek over the years. This is not a claim to pass up!

It is likely there has been some work done after 1900 based on the remnants and items seen in the area. It is estimated by the surveyors that the claim has been worked intermittently in the early 1900’s. No effort to mine for many decades is evident. The gold that you will find on this claim has been washing down from the mines, hills and gulches above and depositing and replenishing the gold on this claim. There is plenty of room to setup your sluice or highbanker and shovel material right next to it.

There is direct road access to this claim and room for staging, parking and other operations. This is an unpatented mining claim for sale. Mineral rights only for recreational mining. The land is public land. This is not a homestead or land for sale.

The best gold is on bedrock. Slim Sam Creek is one of the creeks in the district that was mined by hand in the late 1800’s. There is still good gold in the creek, benches and on bedrock on this claim.

Slim Sam Creek flows into Crow Creek which is historically known for a substantial amount of gold. There are multiple sources of the gold in Crow Creek and Slim Sam Creek is one of them. The gold in Slim Sam Creek is fine and found both in the creek bed as well as the benches. One report talking about the production from Crow Creek states ‘Slim Sam Creek … considered favorable.’ Production from … Slim Sam Creek District from 1908 to 1957 more than 20,130 oz. of gold (Schell 1963).

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. (Earthsearch, Inc. 1983)

Overview of the Mines
The Slim Sam Mine is in an area with rich gold mining history. Estimates of total production for the district by 1911 were between $2 and 8 million. But as with all old mines and mining districts in the Western U.S., the old timers NEVER got it all!

Don’t wait, get your own gold mine before it’s too late. The Slim Sam mine is located in the northeast quarter of section 26. Slim Sam unpatented gold mining claim is about 5500 feet in altitude.

While it is sometimes said old mines have been ‘worked out’ as the saying means there is no gold left, the truth is “it is better to say they are worked over; it is also true that the primitive methods used and the wasteful haste to get rich indulged in, left much of the gold in the ground, so that improved methods … will give even better results than those first obtained.” (MBMG Open Report 466)

Gold And Mineral Mines of Montana Slim Sam

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.

Mining District Information

Slim Sam Creek aka Park aka Hassel District

The Park District has been known under a few different names – Slim Sam Creek and Hassel. Some online references use Slim Sam Creek and others use Park. The Certificates of Location list Park Mining District but either of the other names would be legal also.
The Slim Sam Creek mining district is located ten miles west of Townsend on the Northern Pacific Railway. The district first began to be worked in 1866 when good placer grounds were discovered in Slim Sam Creek. By 1871 it is estimated that $50,000 had been taken from the gravels. Some bars yielded as much as $50 per man per day; the 100 men working the creek averaged $7 per man per day. The work was seasonal for as long as the water lasted. A dam was constructed in the 1870s to control the flow of water and to extend the placer season (Stone 1911; McCormick 1990).
The original placers were found in benches above Slim Sam Creek. Materials ranged from small boulders to clay and sand, all of which were derived from andesite and sediments to the west. The lower Slim Sam Creek placers worked in the 1940s were found in a false bedrock that was one to six feet in thickness and overlain by eight to ten feet of barren gravel (Lyden 1948).
The town of Saint Louis, which was later renamed Hassel, was established in 1875 and, for a time, 35 to 40 miners resided there. The Hassel mining district consists of a cluster of claims at or near the site of the historic mining camp of Hassel. Sometimes referred to in the mining literature as “the mines near Hassel” and other times as “the Hassel mining district,” the area experienced several periods of mining activity. Groupings of mines within the area reflect these periods of activity. The oldest group consists of placer claims which follow the bed of Slim Sam Creek and were located in the 1860s. The Little Giant and W. A. Clark claims, located on Giant Hill in the northeast quarter of Section 2, were discovered in the late 1860s and later worked in the 1870s and 1880s. Two other groups of claims — the Diamond Hill group in Section 36 and the Blacksmith group in Section 1 just west of the the townsite of Hassel — were located as early as the 1860s and 1870s, but the Diamond Hill is primarily associated with the 1890s developments centering on the construction of a 120 stamp mill. In 1890 the Slim Sam Creek district listed the Cyclone group — Patsywa-tomie, Mineral Hill and Silverware — as active. The Park district listed the Clipper, the Gold Dust, Switzerland, Uncle Ed, Silver Bell, Jaw Bone and Hard Cash as active. At that time the Dumphy 20-stamp mill, the Smith 20-stamp mill and the Emanuel 5-stamp mill were actively reducing the ore (McCormick 1990; Ferguson 1906; Swallow 1891).
As with most mining districts, the Park / Hassel / Slim Sam Creek mining district on the east side of the Elkhorn Mountains has been discussed both in combination with other districts or separately with several different boundaries.
Corry (1933) makes no distinction between the Winston, Radersburg and Townsend districts, and discusses the common geological and historical development of the greater district. Pardee and Schrader (1933) define the district as an area on the east side of the Elkhorn Mountains between the Winston and Radersburg Districts. It is drained by Slim Sam Creek and branches of Slim Sam Creek and is reached by a road that goes west from Townsend. Reed includes the upper part of Slim Sam Creek and Eagle Creek which covers the main lode claims.
Small eddy basins on either side of the rocky projections into the stream bed should carry placer gold and are worth careful prospecting ( Corry 1933).
Production from Park (Slim Sam Creek District) from 1908 to 1957 more than 20,130 oz. of gold (Schell 1963), at a gold price of $1800/oz. that works out to more than $36 million.
