Investigated herein are water and sediment geochemistry, and metal attenuation processes associated with natural acid rock drainage originating from black shale formations in the Macmillan Pass area, Clear Lake prospect and Engineer Creek by the Dempster Highway in the Yukon Territory, Canada. The most metalliferous water having pH 3.0, 150 mg/L Zn, 39 mg/L Ni, 2.8 mg/L Cu and 9.1 mg/L As was found in a tributary stream of Engineer Creek with no known mineral deposits occurring in the vicinity. For all three study areas, the water and sediment geochemistry is significantly affected by the local lithology and prevailing metal attenuation processes. Despite their anomalous acidity and metal contents, the natural acid...

This publication discusses fossil fuel and geothermal energy resource in the Copper River-Chugach in Alaska. Topics covered include the energy supply to support Alaska's economy and the geography in the Copper River-Chugach Energy Region. An overview of the mineable coal resource potential, the conventional oil and gas resources, and the unconventional resources including coalbed methane, shale gas and gas hydrates is also provided.
