The Sleeper deposit presents the opportunity to study the details of gold (and silica) depositional processes over a wide vertical interval, extending from depths of 500m to almost the original paleosurface. The proposed research consists of 1) detailed (band-scale) isotopic, trace-element geochemical, and textural studies of the shallow banded ore to document the isotopic and geochemical signature of the ore-forming fluids; 2) studies of deep veins, which will include fluid inclusion, isotopic, mineralogic, textural, and trace-element geochemical analyses. The data generated should provide input for thermochemical modeling, which should in turn provide tests of hypotheses formulated to explain salient features of the banded high-grade ore at the Sleeper deposit. Results will provide new insights into gold depositional processes in shallow epithermal vein systems and how the processes change with depth. It also will refine existing genetic and exploration models for these vein systems.

卧铺存款提供了研究细节的机会 金（和硅）沉积过程 从500米深处延伸到 几乎是原始的古地表 拟议 研究包括：1）详细的（带级）同位素， 微量元素地球化学和结构研究 浅条带状矿石，以记录同位素和地球化学 成矿流体的特征; 2）成矿流体的研究 深部矿脉，包括流体包裹体，同位素， 矿物、结构和微量元素地球化学 分析。 生成的数据应提供输入， 热化学建模，这反过来又提供了 假设的测试制定来解释的突出特点， Sleeper存款的带状高品位矿石。 结果将为金沉积过程提供新的见解 浅成低温热液脉系统中， 这些过程随着深度而变化。 它还将改进现有的 成因及找矿模式 系统.
