In 2012 Kluane Drilling Ltd. visited the Samp prospect and collected samples showing up to 18 ppbgold, 55.5 ppm molybdenum, 129 ppm lead, 5,600 ppm silver, 840 ppm arsenic, 70 ppm bismuth,8639 ppm barium, >300 ppm tungsten, 45 ppm tin, 0.73 ppm tellurium, and 3.25 ppm thallium,including one sample containing an extremely rich 604.5 grams per tonne Au and >300 ppm silver.These numbers and other features found at the property were thought to be indicative of Carlintype mineralization.However, new research done with the support of an Engage Grant supports a completely differentmineralization scenario (intrusion-related, potentially polymetallic), and additional data are necessary to obtainresults that the company can use to design an efficient and effective exploration program.The purpose of the proposed study is to test the hypothesis that the Samp prospect represents anintrusion-related deposit by mapping specific geological features and collecting samples for whole-rockgeochemical assay, petrography, and electron probe microanalysis. This will expand on the mapping andmineralogical and geochemical work done in the original study and will include a detailed evaluation of allparts of the mineralizing system. The results will show if the hypothesis of an intrusion-related deposit iscorrect and will enable the industrial partner to design a suitable exploration program.

2012年，Kluane钻探有限公司访问了Samp勘探区，并收集了高达18 ppp金、55.5 ppm钼、129 ppm铅、5600 ppm银、840 ppm砷、70 ppm铋、8639 ppm钡、300 ppm钨、45 ppm锡、0.73 ppm碲和3.25 ppm铊的样品，其中一个样品中每吨金和银的含量分别为604.5克和300 ppm。这些数字和其他特征被认为是卡林型成矿的指示。然而，在Engage Grant的支持下进行的新研究支持了一种完全不同的矿化情景（与侵入有关，可能是多金属），并且需要额外的数据来获得结果，公司可以使用这些数据来设计高效的勘探方案。该研究的目的是通过绘制特定的地质特征和收集样品进行全岩地球化学分析、岩石学和电子探针显微分析，来验证Samp远景代表一个与侵入有关的矿床的假设。这将扩展在原始研究中所做的测绘、矿物学和地球化学工作，并将包括对矿化系统所有部分的详细评估。研究结果将表明与侵入有关的矿床假设是否正确，并将使工业合作伙伴能够设计合适的勘探方案。
