Louis Lake batholith (a possible source for some of the gold in the construction) (photograph by the creator). A examine of sand and gravel deposits for gold occurrences resulted in the identification of gold colours at many of the areas sampled (Hausel and others, 1992). This widespead incidence of gold could result in the restoration of by-product gold from some sand and gravel operations. Some gems have distinctive white colours and GIA coloration grades as high as D-E-F (grading system ranges from D to X with diamonds of grades D to I being most desirable; see Hurlbut and Switzer, 1979, p.130-132). The metamorphic grade in the South Move area is favorable for a wide range of aluminuous gems together with garnet, andalusite, sillimanite, cordierite, ruby and sapphire. The readability of the gems varies from VVS (very very slightly included) to I (imperfect), thus some gems are evenly included, although near inclusion-free diamonds also occur. As an illustration, the Fisher operation piled gravel and loam on the ore physique while mining different parts of the creek; thus there may very well be considerable virgin floor in Rock Creek (Determine 12). Whether or not there’s enough gold for a business operation remains unknown.
At the time, the dredge had solely been in operation a very a short time, thus we know practically nothing concerning the operation after 1934 till the outbreak of World Conflict II when all gold mining operations were ordered closed by the federal government.. One of those deposits will quickly become considered one of the largest gold mines on the planet. The jade recovered in past years has included material ranging from the poorest high quality black jade to a few of the highest quality apple green jade ever discovered on this planet. A minimum of one false bedrock layer was present in Rock Creek and in Smith Gulch. Sam virtually satisfied by to spend time at CSM to do some isotopic geochemistry on the diamond deposits, but at the time, I was thinking about mapping.

After beginning reconnaissance at South Go within the 1980s, I was awarded a series of COGEOMAP grants from the US Geological Survey, which led me to a nearly decade of geological mapping of the 400 mi2 greenstone belt, its mines, and gold.
