Yellow Bucket Placer, Cedar Creek Mining District, Mineral Co., Montana, USA
Physiography and General Geology: See: US Geological Study
On September 11, 1971, John B. Burleson, mining engineer, Regional Office, Missoula, Montana, accompanied by Geoffrey F. Wilson, resource assistant, USFS Superior Ranger District, conducted a mineral examination of the Yellow Bucket Placer Mining claim, noting in their report (No. 2810-May 15, 1972) “ The Yellow Bucket Placer Mining Claim is located in the vicinity of the confluence of Bonanza, Missoula, and Oregon Gulches; roughly 2 miles north of Oregon Peak. The area is mountainous with a maximum altitude of 6,863 feet at Mink Peak. The slopes support a relatively thick cover of timber. The area of the claim is generally sloping, however, the relief above is quite extreme.
Bedrock in this portion of the Bitterroot Mountains has been assigned by Ross (1963), Northwest quarter geologic map of the Belt Series to the Wallace Formation. The formation is composed of quartzite, argillite, limestone, dolomite, and a wide range of mixture of these rock types. The most diagnostic characteristic of the formation as a whole is the presence of calcite, ferro-dolomite, or low-iron ankerite, or a mixture of these minerals. A thickness of about 10,000 feet of Wallace Formation is exposed in the Dry Creek valley approximately 7 miles north of this site. Colors range from white to dark gray with shades of reddish to yellowish-brown; typical of weathered surfaces.”
The 1971 report references the mining developments at that time, stating, “Placer gravel is being washed from two, hand-dug pits located about 150 feet due east of the cabin and Oregon Gulch. Water is conveyed to these pits by approximately 400 feet of 2-inch plastic pipe which then moves the screened gravel 150 feet through 10-pipe to a sluice box at the water’s edge of Oregon Gulch.”
Mineral Values: In the 1971 evaluation of mineral values, the USFS report advises, “ Seven pans of gravel were washed. The material was taken from two, hand-dug pits as indicated by the claimants. Montana Laboratory Company, Philipsburg, Montana, reported 145.39 milligrams of free gold in the concentrated black sands saved from the seven pans of gravel. This gold calculates to a value of $11.71 per yard, assuming a fineness of 900 and a $49 gold value.”
Do the math - 50 years ago when this sample was assayed, the price of gold was less than $50 an ounce . Today's gold price is almost 40 times higher!
