Chain Lakes is located in an area of rugged cirques and sharp ridges where mining has been occurring since 1896. The mine has been called Dutch Miller mine where prospecting has been on sulfide minerals and high grade copper deposits found in quartz - tourmaline shoots in the granodiorite rock.
Artisanal mining can include activities as simple as panning for gold in rivers, to as complex as development of underground workings and small-scale processing plants. . Miners use a variety of methods to locate minerals, including historical knowledge, the observation of other minerals or rocks, or technology such as mineral detectors and audio-based reflection seismology surve

An uncut, rough yellow sapphire found at the Spokane Sapphire Mine near Helena, Montana.

Although blue is the best-known sapphire color, it occurs in other colors, including gray and black, and also can be colorless.
The soft stone is easily carved and is not degraded by heating. The slick surface of soapstone allows the finished object to be easily removed. Welders and fabricators use soapstone as a marker due to its resistance to heat; it remains visible when heat is applied. It has also been used for many years by seamstresses, carpenters, and other ...
Malachite is a copper carbonate hydroxide mineral, with the formula Cu 2 CO 3 (OH) 2.This opaque, green-banded mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses, in fractures and deep, underground spaces, where the water table and hydrothermal fluids provide the means for chemical precipitation.
An uncut/rough yellow sapphire found at the Spokane Sapphire Mine near Helena, Montana "Yogo sapphire" is the preferred term for gems found in the Yogo Gulch, whereas "Montana sapphire" generally refers to gems found in other Montana locations. [18] More gem-quality sapphires are produced in Montana than anywhere else in North America. [18]
