Upper Beaver is a Au-Cu mineral deposit associated with magnetite-bearing veins and breccias, and hosted by altered volcanic and plutonic rocks. It is thus a type of mineralization that is different from the typical lode gold veins of the Kirkland Lake and Larder Lake area. The origin of the Upper Beaver deposit is presently poorly constrained and several deposit models have been proposed to classify it, including Archean intrusion-related and Iron-Oxide-Copper-Gold (IOCG) deposit types. Understanding the origin and setting of the Upper Beaver deposit has important implications to orient mineral exploration for similar types of mineralization in the Superior Province. The proposed research program will investigate the regional tectonic and magmatic setting of the Upper Beaver deposit environment in order to integrate the deposit-scale studies to the larger scale. In this context, the proposed research program will aim to document several relevant aspects of the deposit in order to constrain its origin: 1) the structural geology of the deposit breccias in order to place constraints to their origin; 2) document the mineralogical paragenesis and its spatial distribution in 3 dimensions; 3) geochronology to constrain magmatic and hydrothermal events; and 4) use stable isotope (H, C, O, S) and fluid inclusion to decipher the origin and evolution of the hydrothermal fluids that formed the deposit. In addition, the research program will measure the petrophysical properties of representative samples and along downhole surveys to provide key data needed to interpret geophysical surveys in mineral exploration. Collectively, these results will be integrated into a regional framework that will be useful for more efficient predictive targeting for this type of Au-Cu mineralization by the Canadian mining industry.

上海狸是一种与含磁铁矿的静脉和角砾岩相关的Au-cu矿物质沉积物，并由改变的火山岩和岩石岩石托管。因此，它是一种矿化类型，与柯克兰湖和拉德湖地区的典型矿物静脉不同。上海狸沉积物的起源目前的约束较差，并且已经提出了几种沉积模型来对其进行分类，包括与大老式的入侵相关和氧化铁 - 氧化 - 氧化 - 氧化矿床（IOCG）的沉积物类型。了解上海狸沉积物的起源和设置对上省类似类型的矿化类型的方向矿物勘探具有重要意义。拟议的研究计划将研究上海狸沉积环境的区域构造和岩浆环境，以将沉积尺度研究整合到更大范围内。在这种情况下，拟议的研究计划将旨在记录存款的几个相关方面，以限制其起源：1）存款角砾岩的结构地质，以便对其起源施加约束； 2）记录矿物学旁催化剂及其空间分布在3个维度上； 3）限制岩浆和热液事件的年代学； 4）使用稳定的同位素（H，C，O，S）和流体包含来破译形成沉积物的热液流体的起源和演变。此外，该研究计划将测量代表性样品的岩石物理特性和沿井下调查，以提供在矿物勘探中解释地球物理调查所需的关键数据。总的来说，这些结果将集成到一个区域框架中，该框架将对加拿大采矿业对这种类型的Au-Cu矿化进行更有效的预测定位有用。
