以上儲量的所有信息由 Phil Fillis 和 Chris Arnold 兩位先生負責匯總，這兩位先生都是澳大利亞礦產冶金協會的成員。
2005 年 5 月份開工建設年處理 80 萬噸金礦石，年產黃金 10 萬盎司規模的生產線。2006年11月12日選廠竣工并舉行了試車投產典禮。目前選廠正在調試生產階段，預計07年 3月份能夠進入正常生產。礦山服務年限約12年，最終產品為合質金，生產期年均產黃金2412.11公斤。
礦山的基礎設施已基本完善， 35kv 電網將已經架設到礦山。水源地離礦山約 2 公里遠， 礦區已通聯通和移動手機通訊網和高速因特網，現場的新生活區已投入使用。項目按照北美環境準則進行建設，同時也嚴格遵守中國環境法。礦山對環境的影響將會很小。
采礦將在金龍溝和青龍灘同時進行露天開采，年采剝量約 150 萬立方。目前已首先處理青龍灘的礦石，青龍灘的礦石運至 19 公里遠的金龍溝選廠進行處理。采礦主要由本公司的采礦隊伍來承擔，月平均剝離量為60萬立方。2007年計劃剝離總量為20，500，000立方米。
選廠以碳氰法工藝處理氧化礦，并通過浮選 / 焙燒流程來處理原生礦。選廠的年設計處理能力計劃為 80 萬噸。北京礦冶研究總院，具體負責選廠的詳細設計、設備采購和建筑施工，英國 GBM 選冶有限公司做為業主代表對選廠建設施工進行了監管。
目前公司共聘用了員工 450名，其中青海本地員工 403名，占員工總數的89.56％。公司以人為本，重視員工的發展和培養，對員工進行專業技能培訓，讓員工充分發揮其專業才能和技術特長。公司根據員工的能力和工作業績表現向員工提供了優厚的薪酬和福利待遇。
