will feed a single processing plant. There is also a potential for a mining phase to feed multiple <br /> processing plants. Planned mining areas are described below and are shown on Map C-1 and <br /> Map C-2. <br /> • Mining Area I <br /> Mining Area 1 surrounds the most recent area worked by Hallenbeck. Grades are very close to <br /> the cutoff grade, but volumes are sufficient to target. It is possible, based on drill hole spacing, <br /> that higher grade zones were missed south of the observable workings. Resistivity logs also <br /> indicate a paleochannel that was missed by drill holes and was thus unexplored. The northern <br /> portion of Mining Area 1 has relatively high grades but transitions to moraine material and <br /> possibly was too difficult to wash with Hallenbeck's equipment, hence the lack of mining. The <br /> eastern edge of this area is targeted for additional exploration and may be the largest remaining <br /> resource in the entire project. It follows the water course of Corske Creek that is the most <br /> probable gold source for the deposit. <br /> • Mining Area 2 <br /> Mining Area 2 lies immediately north of the Derry Dredge workings. Grade data indicates that <br /> values are generally lower than the main northern channel but still remain above cutoff grade for <br /> modern equipment. Additionally, the area was likely difficult to access with a dredge. <br /> Resistivity logs indicate a number of paleochannels perched higher than historic dredge <br /> workings. These are very compelling targets especially when metallurgical test data presented in <br /> the Aurora dataset is considered. <br /> • Mining Area 3 <br /> Mining Area 3 targets material missed by General Gold Corp's floating dredge. Based on <br /> available datasets and site visits an observable buffer of material was left between the Derry <br /> Dredge workings and the General Gold Corp Dredge. It is likely that this buffer was left to <br /> maintain and support the pond for the dredge. If the Derry Dredge workings were intercepted, it <br /> would likely become difficult to maintain the desired pond elevation. It is likely this area is the <br /> highest-grade remnant left from previous mining operations. <br /> Box Creek Placer Mine Greg 1. k*i and A&%cintm PUA <br /> September 2018 D-3 <br />
