The prospect is on land that has been selected for patent by the Sealaska Native Corporation and the Kake Tribal Corporation.
Location: In 1969, a claim was staked for gold on a small creek locally called 'Little Creek'. The claim was centered about 0.2 mile inland and about 0.4 mile north of hill 815 in about the middle of the north boundary of section 30, T. 57 S., R. 72 E.
Geology: This prospect is one of a group of similar deposits (PA021 to PA031) that are scattered along the south shore of Saginaw Bay, on the peninsula north of Saginaw Bay, and on the Keku Islands. They occur in a heterogeneous section of unmetamorphosed volcanic, carbonate, and clastic rocks that vary in age from Silurian to Triassic (Muffler, 1967). The mineralization generally consists of veins, veinlets, and irregular pods that contain base metals and barite (Still and others, 2002). There are no plutonic rocks in the immediate vicinity; however, the sedimentary rocks are cut by scattered gabbro dikes. The origin of the deposits is uncertain although most appear to be epigenetic. Various origins have been proposed including that they are remobilized massive-sulfide deposits, that they are related to a buried intrusive, or that they are Mississippi-Valley-type deposits. A single claim was staked at this site for gold in 1969 on what is informally called 'Little Creek'; there has apparently been no activity since. Still and others (2002) investigated the area and collected several samples. A sample of altered volcanic rocks contained 1,359 parts per million barium but no gold or other metals. The rocks in the area are rhyolite flows with jasper veinlets and volcanic breccia of the Keku Volcanics of Triassic age.
Workings: A single claim was staked for gold in 1969; there has apparently been no activity since. Still and others (2002) investigated the area and collected several samples.
Age: The mineralization, if any, is younger than the Triassic, volcanic host rocks.
Reserves: None.
