Older Triassic and Permian layers of phyletic argillite, sandstone, and shale are also present, pressing against the younger rocks along thrust faults. Steep, north-trending faults cut the entire area, and the creek itself flows over Quaternary alluvial depositstypically 6 to 12 feet of silt interspersed with layers of slate fragments. Both historical and recent sampling have confirmed the presence of gold and scheelite in these deposits. Placer mining at Little Boulder Creek dates back to 1917, with nearly continuous operations through the 1930s. Mining resumed intermittently from 1967 through the early 2000s, including overburden stripping, trenching, test hole digging, sluicing, and bulldozer-assisted sampling. Operators included Farrell & Higgins, J.L. Wood, Vern Petefish, and Windy Hill Mining. Notably, sluicing operations in the 1990s processed thousands of cubic yards, confirming the continued presence of gold and scheelite. Despite extensive historical activity, no comprehensive public records of production exist, highlighting the site's potential for modern exploration. Little Boulder Creek offers a rare opportunity to explore a historically productive placer system with demonstrable mineralization. Its favorable geology, historical workings, and proven recovery of gold and scheelite provide a strong foundation for renewed mining operations. The property is well-suited for contemporary placer mining techniques and presents a compelling investment prospect for those seeking both economic potential and the experience of mining in interior Alaska's rugged, largely undeveloped wilderness.
