Detailed Information

Treasure Mountain Mining Property

The Treasure Mountain mining property is a historic mine in the Elliston mining district located in Powell County, Montana. The Treasure Mountain has an adit of several hundred feet and a shaft of another several hundred feet. On the adit dump, vein quartz containing tourmaline and pyrite has been found.

The Treasure Mountain property is 20.66 acres. The mine consists of several collapsed adits and shafts with multiple drifts and a large ore shoot as seen in the pictures on our website. 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. We have done our best to extract the information from each source and determine exactly 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.

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 of silver, 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.

When we visited it, this past fall all the adits/shafts were collapsed and we were not able to enter at that time. There is plenty of ore on the dumps. 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.

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 veins. 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.

2 Veins-Big Dick strikes N and dips 20N. Blanket vein-strikes E and dips 20N. Blanket vein cuts the other and is the main source for the mine. The folding squeezed and crushed the rocks, opening them for mineralizing solutions which partly replaced them with silica and introduced gold bearing pyrite. Some quartz contains large columns of black Tourmaline intergrown with pyrite. The Northern Rocky Mountains physiographic province of the Rocky Mountain System characterize the geomorphology of the surrounding area. TOURMALINE IN WALL ROCK, TRACE OF CHALCOPYRITE IN SPHALERITE. Ore body width 3.51 feet. Minerals at the mine: Calcite, Pyrite, Quartz, Tourmaline, Chalcopyrite, Galena, Gold, Sphalerite, Silver, Copper, Zinc. 3 OUNCE PER TON GOLD, SOME UP TO 5 OUNCE PER TON GOLD.
