The Kootenai country of Lincoln County in the far northwest corner of Montana was among the last regions of the state to attract systematic mining development. The mountains along the Canadian border were remote, the winters were severe, and the transportation connections that made mining economically viable elsewhere in Montana were slow to reach the Kootenai drainage. When gold was finally discovered in the district that would produce the camp of Sylvanite, the men who came to work the deposits were working at the edge of the accessible world, dependent on supply routes that stretched across difficult terrain and subject to the particular hardships of a high-latitude mining frontier.

The gold deposits in the Sylvanite district were discovered in the 1890s, when prospectors working through the mountains of Lincoln County found ore in the quartz veins that cut through the metamorphic rocks of the Kootenai Range. The camp that grew up around the discovery took the name Sylvanite from the gold-silver telluride mineral that was present in the ore, a name that was used for mining camps across the West wherever telluride ores were found. The mineral's name itself came from the Latin word for silver, a reminder of the classical education that the nineteenth century's mining engineers often brought to their work.

The initial development of the Sylvanite district was hampered by the same transportation problems that limited mining activity throughout Lincoln County. The nearest railroad connection was distant, and the cost of moving ore to a smelter and supplies back to the camp was high enough to make marginal ore bodies unprofitable. The men who worked the district in its early years were working on the assumption that the ore bodies would prove rich enough to justify the transportation costs, and for a period in the 1890s that assumption seemed justified.

The camp's most significant period of development came in the early twentieth century, when Canadian investors recognized the potential of the Sylvanite district and formed the Lincoln Gold Mining Company in 1910 to operate the Keystone and Goldflint mines. The Canadian capital brought new energy to the district, and the company's operations were more systematic and better capitalized than the individual prospectors who had worked the area in the 1890s. The Keystone and Goldflint mines were the district's principal producers, and the camp that supported them had the character of a company town rather than the loose collection of independent operators that characterized the earlier phase of development.

The Lincoln Gold Mining Company's operations at Sylvanite were productive for a period, but the combination of the remote location, the high cost of transportation, and the difficulty of the ore bodies made sustained profitability elusive. The company worked the Keystone and Goldflint mines through the 1910s, but the returns were insufficient to justify continued investment, and the operations were scaled back and eventually abandoned. The camp contracted as the company's workforce was reduced, and by the time of the First World War Sylvanite had entered the long decline that would eventually leave it an abandoned site.

The Kootenai country of Lincoln County was transformed in the early twentieth century by the arrival of the Great Northern Railway, which opened the region to timber and agricultural development that proved more durable than the mining economy. The towns that grew up along the Great Northern's route, including Libby and Troy, became the centers of economic life in Lincoln County, and the mining camps in the mountains above the railroad corridor were left to decay as the population concentrated in the valley communities.

The history of Sylvanite reflects the particular challenges of mining in the far northwest corner of Montana. The ore was real, the gold was there, and the men who worked the district were skilled and determined. But the combination of remoteness, severe winters, and high transportation costs imposed limits that even well-capitalized operations could not overcome. The Lincoln Gold Mining Company's investment in the Keystone and Goldflint mines was a serious attempt to develop the district's potential, and its failure was a function of geography and economics rather than a lack of effort or capital.

The mineral name sylvanite itself carries a history worth noting. The gold-silver telluride mineral was named for Transylvania, the Romanian region where it was first described by European mineralogists in the eighteenth century. When prospectors in the American West encountered the same mineral in their ore samples, they adopted the name, and it appeared in the names of mining camps from Colorado to Montana wherever telluride ores were found. The Sylvanite camp in Lincoln County was one of several in the West that carried the name, a small reminder of the global connections that linked the mining industry of the American frontier to the scientific traditions of Europe.

The Great Northern Railway's arrival in the Kootenai country in the 1890s transformed the region's economic geography, but it did not transform it in the way that the mining interests had hoped. The railroad made the timber resources of Lincoln County accessible to markets, and the lumber industry that developed along the Kootenai River proved far more durable than the mining economy. The towns of Libby and Troy grew as lumber and railroad towns rather than mining towns, and the camps in the mountains above the valley were left to decay as the population concentrated in the communities that the railroad had created.

What Remains Today

The Sylvanite site is located in the mountains of Lincoln County, in the Kootenai country near the Canadian border. The physical evidence of the mining operations includes the mine workings, waste rock piles, and whatever structural remnants may survive in the forest. The site is not developed for public interpretation, and access requires travel on forest roads through the Kootenai National Forest.

The surrounding landscape is part of the Kootenai National Forest, and the area provides opportunities for hiking, hunting, and backcountry travel in the mountains of the far northwest corner of Montana. The combination of the mining history and the remote mountain landscape makes Sylvanite a destination for visitors interested in the less-visited corners of the state's history.

Visiting

Sylvanite is located in Lincoln County, accessible via forest roads from the Kootenai River valley. Libby, the Lincoln County seat, is the nearest city with visitor services, located on US Highway 2 along the Kootenai River. The Kootenai National Forest's Libby Ranger District can provide current road and access information for the Sylvanite area.

Troy is approximately 18 miles west of Libby on US Highway 2 and is the nearest town to the Sylvanite district. Kalispell, the Flathead County seat, is approximately 90 miles east of Libby on US Highway 2.
