Historic Big Treasure Mountain
20.66 Acre Placer Claim – Elliston District – Powell County, Montana
The Historic Treasure Mountain Lode Mine for sale, a 20.66 Acre Unpatented Lode Mining Claim on federal land managed by the U.S. Forest Service. The claim is located just outside of Elliston, Montana in the Elliston Mining District in Powell County, MT and has been properly marked. All claims have been carefully surveyed, mapped and researched. MMC #241031
The Treasure Mountain claim is 20.66 acres. The claim consists of several collapsed adits and shafts with multiple drifts and a large ore shoot as seen in the pictures. Treasure Mountain mine is also known under the following names: Big Dick/Evening Star/Golden Anchor. Although the Golden Anchor is actually located slightly away from this mine, there are reports that include the Golden Anchor as the Big Dick/Evening Star/Treasure Mountain mine. As if that wasn't confusing enough another mine, the Black Jack/Big Nine mine is also referenced as part of the Big Dick Mine. Gold And Mineral Mines of Montana LLC own the Big Nine/Black Jack mine as well and it can be viewed on our website. We have done our best to extract the information from each source and determine eaxctly which mine is which. To the best of our knowledge all the information on this listing pertains only to the Treasure Mountain/Big Dick/Evening Star mine.
The Treasure Mountain Mine is a short drive out of Elliston, MT. A dirt road winds up into the hills and right to the base of one of the dumps. This is an old and rarely visited area. The road runs to the base of the hill below the mines then from there the road to the mine is ATV or UTV only. There is a good spot for parking near the dump, in a small clearing at the mine. The claim covers a full 20.66 acres, and has been written to cover the general trend of the lode along with a majority of the buildings in the area. There are numerous buildings in disrepair including a hotel, supervisors residence, the Big Dick Mill and shaft. We spent two days photographing as much as we could before we were chased out by a snow storm and even with that much time we didn't get everything photographed! We have over 150 pictures included with this listing. This is a very extensive mine and a lot of work was done here. The mine was one of the largest producers in the district. This is not a mine to let pass you by.
The mine is an old cut. It appears to have been one of many mines in the area that worked the Big Dick and Blanket Veins. The Big Dick (or Evening Star) is located near the summit of Black Man Mountain about eight miles south of Elliston. The mine recorded production nearly every year from 1905 to 1940. In 1905 the mine extended the shaft from 250 to 300 ft and did 575 ft of drifting. A steam hoist and pump extracted the ore and water from the mine. The mine development ultimately included a 1,000 ft long adit connected to the 300 ft shaft and a 200 ft raise. The mine worked the Big Dick vein and the Blanket vein. Some of the ore shoots were 3.5 ft thick and some of the ore returned 5 ounces of gold to the ton. The mine produced gold/silver/lead ore from 1906 to 1910 which was shipped to the East Helena and Washoe smelters. The mine was again briefly operated in 1923 and 1927. Total production was said to have been about $500,000 (Pardee and Schrader 1933; Walsh 1906).
Production from mines reported by McClernan (1973) spanned the years of 1902 to 1954, intermittently, and totaled 16,200 ton of ore yielding 7,687 ounces of gold, 51,236 ounces ofsilver, 1,870 pounds of copper, 716,553 pounds of lead and 3,800 pounds of zinc. The majority of the production came from the years between 1905 and 1923.
The tailings offer a good mining opportunity. Over the years some of the gold has washed down to the bottom of the tailings pile from the top. The previous miners used the best technology of their time but they left a huge amount of good ore behind in the tailings. In addition, sulfide ore was harder to treat back then and most times it was thrown out on the tailings piles at old mines. Some of the lode mines from the 1800's are full of gold to this day because the technology to process sulfide ore was not available back then so they threw it out and over time the ore has been sitting out in the weather oxidizing which then releases the gold. Many old mine dumps are very profitable for this reason alone. You'll find unprocessed gold ore throughout the hillside.
OVERVIEW OF THE MINES
Several adits and a shaft are included in this claim and several buildings are included. The mines are on the Big Dick and Blanket veins but currently none of the adits or shaft are open. The new owners will want to dig out the portals of the adits to get to the gold/silver viens. Opening the portals will also help to dry out the mine. A dry mine is safer than a wet one. We estimate it would take about a few of days for 1 or 2 guys to dig out each portal.
The historical documents show the mine was active from 1915 to 1930 no production figures have been found for the mine. Once the adits portals are opened a locked gate would be required by law to prevent people from going inside and getting injured. The drift and raise are directly on the rich ore bodies. The shaft connects lower drifts on the rich gold/silver veins and to access these lower drifts would require opening the shaft and building a safety platform.
The fact that such rich samples are so easily found right from the start make this mine an easy one to begin making a profit from right away. The workings are impressive, the entire mine site is currently very large but could quickly be made larger.
Mine operations consist of surface and underground workings. There is one known shaft. Subsurface depth reaches a maximum of 91 meters (300 feet) and extends 457 meters (1,500 feet) in length. The ore mined is composed of sphalerite, gold and galena with waste material consisting primarily of pyrite, tourmaline and quartz. The ore body takes a blanket shape extending 1.07 meters (3.51 feet) thick.

MINING DISTRICT INFORMATION
|The Elliston mining district is about 20 miles west of Helena and south of the Little Blackfoot River. It includes the town of Elliston which is the first town on the Northern Pacific Railroad west of the Continental Divide. The mining district includes the town of Elliston but is generally south of the river in mountainous, heavily-forested terrain. Early reports on the district described about 15 productive mines, most of which were from five to 11 miles south of the town.|
|The geology in the vicinity of Elliston consists of an apparently conformable succession of limestone, quartzite and sandstone. The lowest formation is the Madison limestone which is overlain by the Quadrant quartzite, near the top of which occurs a bed of high-grade phosphate rock. To the south of Elliston rhyolites are present and persist on the flanks of the mountains to 6,200 ft. The ore deposits of the Elliston district contain values chiefly of lead-silver, some of which contain considerable gold. The ore minerals are galena, pyrite, sphalerite, arsenopyrite and tetrahedrite in a quartz-carbonate gangue (Schrader 1929; Pardee and Schrader 1933).|
|The Elliston district began as a placer operation along the Little Blackfoot River during the 1860s... It was not until the 1890s, when lode mining was developed south of town, that the district began to produce significant amounts of ore. Most of the production from the lode mining occurred between 1890 and 1908, at which point the total production was estimated at $2,750,000. Most of this production came from the Big Dick (or Evening Star), Monarch, Julia, Flora, Ontario and Twin City mines. However, during the first half of the 1890s, the town and the area's primary economic base was woodcutting. Cutting cord wood for the Anaconda Copper Mining Company's smelter at Anaconda employed more than one hundred wood cutters and it was during this period that the town of Elliston reached its peak in population and activity. However, in 1894 and again in 1895, fires destroyed the town (Lyden 1948; Robertson 1956; Wolle 1963).|
|Knopf (1913) reported that by 1911 there was little mining in progress in the Elliston district and throughout the region. Pardee and Schrader (1933) indicate that some sporadic mining occurred in the Elliston district during the 1910s and 1920s with a total production of about $200,000, with $70,000 of this coming from gold and the remainder from 90,000 ounces of silver, 700,000 pounds of lead and 90,000 pounds of copper (Pardee and Schrader 1933).|
|Robertson (1956) reported periodic mining activity in the district since then, although no important mines have been developed. He estimates the total production for the district at somewhat more than $3,100,000. During the period from 1909 to 1954 the district marketed about 7,600 ounces of gold, 149,000 ounces of silver, 98,000 pounds of copper, 1,560,000 pounds of lead and 197,000 pounds of zinc (Anderson 1990; Robertson 1948).|
|The country rock is a coarse andesitic breccia, apparently bedded; the strike is N. 50° E. and the dip 20° NW. It is much jointed so that determinations of strike and dip of bedding are likely to be unsafe. The ore deposit is said to be a blanket vein developed by a shaft 300 feet deep and is said to dip north at a low angle. The ore carries galena, pyrite, sphalerite, and arsenopyrite in a quartz gangue; some of the quartz contains numerous large columns of black tourmaline intergrown with pyrite. The ore is reported to have been high grade, carrying as much as 3 ounces of gold a ton. During 1906 a gold-silver-lead ore was shipped to the East Helena smelter and a production was maintained until 1910. The deposit was worked to the west end line; during 1911 the lessees were engaged in sinking a shaft near this end line on the adjoining claim, which is one of a group known as the Finnish or Weston group. It was expected that the Big Dick vein would be struck at a depth of 150 feet.|
