Some of the largest gold nuggets found in Alaska are from the district, which lies along the Yukon River.〔Alaska Resource Data Files ''http://ardf.wr.usgs.gov/ardf_data/RB_refs.txt''〕 The placers are mostly deeply buried, and most were originally worked with shafts and drifts. Dozens of creeks in the district were mined, many more bear gold prospects. Cassiterite, platinum, scheelite, allanite, and native bismuth have been recovered along with gold from placer mines in the district.〔Significant Metalliferous Lode Deposits and Placer Deposits of Alaska, Nokleberg, et al., USGS Bulletin 1786, 1987〕 ==Swift Creek== The largest gold nugget in Alaska (294.10 troy ounces) was found on Swift Creek in 1998.〔(Alaska's Largest Gold Nuggets )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Ruby–Poorman mining district」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
