It is probably the oldest lead-zinc camp in Montana ... The Lee Mountain Lode was discovered in 1864 and the Eureka Mine in 1865. However, little mining occurred until 1885 when the Northern Pacific spurline was constructed to the district. During the 1880s a number of mines were developed with the most productive ones being the East Pacific, Lady Washington, John McGraw, Eureka and Porphery Dike. Some of these mines were opened to depths of up to 500 or 600 ft. One of the deepest, the Lee Mountain, has produced more than $1.5 million and the Valley Forge, which is 325 ft deep, has produced more than $200,000.

*The main road through Rimini was completely excavated and backfilled to remediate contaminated material. Approximately 18,000 cubic yards of waste were removed from one mile of Rimini Road. Removal of this waste reduces the potential for residents to be exposed to contamination as well as prevents future erosion and distribution of wastes via the adjacent Tenmile Creek. *Nearly all of the residential yards were remediated, with newseptic systems A septic tank is an underground chamber made of concrete, fiberglass, or plastic through which domestic wastewater ( sewage) flows for basic sewage treatment.

Approximately 6,000 cubic yards of waste were removed from the yards in Rimini and 9,000 cubic yards from the Lee Mountain site.
