Geophysical assessments of the Valentine Lake gold deposit property, Central Newfoundland

将在纽芬兰西部的瓦伦丁湖财产上进行严格的地面地球物理调查，该财产含有两个重要的金矿和至少三个额外的前景。 由硕士生和本科生进行的主要目标是：用探地雷达（GPR）绘制地表覆盖图，以计算水储量，帮助未来矿山的钻探和上部结构放置，并绘制隐藏断层图;并利用GPR结果，使用地表重力测量来描绘金矿所在区域。 其他计划中的活动包括沼泽和湖泊沉积物岩心取样以及磁力和自然电位调查。采样，除了允许深度校准的探地雷达数据，将提供有关纽芬兰沉积物的碳和水预算的信息，并可能表明过去的侵蚀模式。磁测结合探地雷达的结果，将有助于描绘出勘探区附近的地下构造. SP测量是在存款上测量表面电压，是探索性的：不知道它们是否会提供与矿化、结构或表面物质相关的数据。 所有的测量仪器都是纪念大学最先进的地球物理设备库的一部分。 这项研究将提供有价值的信息，业主和更广泛的资源勘探界对地面地球物理学的效用超过一个存款类型，发生在整个纽芬兰岛的带。 虽然没有地球物理调查可以直接探测黄金，但这些调查将有助于找到最佳的钻探区域，并以最小的环境影响规划矿山。 该项目雇用的学生将在一个环境中接受一些高精度地球物理方法和数据分析方面的培训，使他们能够成为高素质的人才。

Rigorous ground geophysical surveys are to be carried out in western Newfoundland over the Valentine Lake Property, which contains two significant gold deposits and at least three additional prospects. The main aims, carried out by an MSc candidate and undergraduate students, are: to map surficial cover with ground penetrating radar (GPR) in order to calculate water reserves, help with drill and superstructure placement for the future mine and map hidden faults; and utilizing the GPR results, to use surface gravity measurements to delineate the region hosting the gold. Other planned activities include bog and lake sediment core sampling, and magnetic and self-potential (SP) surveys. The sampling, in addition to allowing depth calibration for the GPR data, will provide information on carbon and water budgets of Newfoundland sediments, and may indicate past erosion patterns. Magnetic surveys, in combination with GPR results, will to help delineate subsurface structures near the prospects. The SP surveys, where the surface voltage is measured over the deposit, are exploratory: it is not known they will provide data relevant to the mineralization, or to structure, or to surficial materials. All the survey instruments are part of the state-of-the-art geophysical equipment pool at Memorial University. This research will provide valuable information both to the property owners and the wider resource exploration community on the utility of ground geophysics over a deposit type that occurs in belts across the island of Newfoundland. Though no geophysical surveys can directly detect gold, the surveys will help in finding the best regions to drill and for planning the mine with minimal environmental impact. Students employed in the project will be trained in a number of high precision geophysical methods and data analysis in an environment that will prepare them for employment as highly qualified personnel.
