Long Canyon is a sediment-hosted disseminated gold deposit.The gold mineralization at Long Canyon is best described as sediment-hosted, Carlin-type gold mineralization.The mineralization identified at Long Canyon shares many of the characteristics of Carlin-type gold mineralization, including:- Stratigraphic control on mineralization - mineralization is hosted primarily in limestone, particularly in silty, thin-bedded units; - Structural control on mineralization - mineralization occurs in karstic cavities, collapse breccias, and anticlinal fold hinges;- Geochemical association - elevated arsenic, mercury, antimony, and thallium accompany the gold mineralization, while silver and base-metal concentrations are low; and- Alteration - mineralization is associated with decalcification, silicification/jasperoid, oxidized variants of pyrite and arsenical pyrite or arsenopyrite, and clay alteration.The Long Canyon project also displays some characteristics that are unlike typical Carlin-type gold deposits. The prevalent association of hematite with gold mineralization at Long Canyon is not a common characteristic among all Carlin-type deposits, although this phenomenon is associated with weathered/oxidized portions of some of the deposits.
