The Martha Q mine is in Denali National Park and Preserve.
Location: The Martha Q mine (Cobb, 1980 [OFR 80-363]) is on the western- most spur of Quigley Hill at an elevation of about 2700 feet. The location is accurate within about 250 feet. The mine is included in location 8 of Cobb (1972 [MF 366]) and in location 6 of MacKevett and Holloway (1977). Martha Q is a patented claim. The location of the claim is shown at a scale of 1:12000 in Hawley and Associates (1978), and the location of the mine shaft is about coincident with their deposit number 129.
Geology: The area of the Martha Q mine is underlain by low-grade metamorphic rocks of the Spruce Creek sequence (Bundtzen, 1981). The mine is on the west flank of a northwest-trending body of locally conglomeratic quartz schist (Seraphim, 1962; Hawley and Associates, 1978, fig. 4.1-A(1)-3). The deposit consists of a mineralized quartz vein that strikes NNW, about parallel to the orientation of the quartz schist body. The vein dips steeply NE. It occupies a fault that strikes obliquely to the dominant, northeast- striking veins of the Quigley Hill area. Locally, the vein consists mostly of galena. A selected sample from the mine assayed 0.08 ounce of gold per ton and 284.2 ounces of silver per ton (Davis, 1923, p. 125). Four tons of this high-grade vein material was picked and shipped with ore mined at the Gold Dollar (MM110) in 1921-22.
Workings: A shallow shaft and a few trenches were excavated in 1921-22 (Davis, 1923). In 1983, the property was owned by Kantisna Mines Inc., and Maurice Butler (Thornsberry, McKee, and Salisbury, 1984, v. 2, location 29).
Age: The deposit is assumed to be Eocene (see record MM091).
Production: Four tons of ore shipped in about 1921-22 contained 1136 ounces of silver (Bundtzen, Smith, and Tosdal, 1976, table 1).
