PPX Mining Corp. announced that the company has received results from four additional infill and resource confirmation/expansion diamond drill holes on the Callanquitas structure at its Igor Project in northern Peru. This drilling is part of a comprehensive underground test mining and bulk sampling program designed to expand and upgrade the existing Inferred resource leading to a Pre-Feasibility Study ("PFS") evaluating mine development opportunities at Igor, expected in First Quarter 2018. The drill results reported below demonstrate continuity in the highest-grade portions of the resource, defining a northerly raking geometry to the higher-grade mineralized zones. In addition, the high-grade zones remain open at depth, further underscoring the gold and silver resource expansion potential of the Callanquitas structure. Diamond drill hole CA-17-86 was designed to in-fill and validate previously drilled high-grade gold and silver resources along section NW4690. The thick interval of high grade gold and silver mineralization intercepted by this drill hole (12.6m grading 8.34 gpt Au and 207 gpt Ag (11.10 gpt Au Eq) including 2.0m grading 17.41 gpt Au and 200 gpt Ag (20.08 gpt Au Eq)), coupled with previous drill intercepts in this portion of Callanquitas structure, defines a northerly trending rake to high precious metal grades. Individual assays within this intercept range up to 58.24 gpt gold with 510 gpt Ag (65.04 gpt Au Eq) over 0.65m (250.25 ­ 250.9m), some of the highest grades seen in drilling to date at Callanquitas. This zone is open down-rake to the north. Drill hole CA-17-87 was targeting an area down-dip from previously reported drill holes CA-17-77 and -79 on section NW4780 (Please see PPX Mining Corp. press release dated November 7, 2017). Hole -87 cut the Callanquitas structure approximately 55 metres vertically below hole CA-17-77 (2.6m grading 9.21 gpt Au and 9.3 gpt Ag) and successfully intercepted the down-dip extension of this gold and silver mineralized zone: 5.5m grading 8.46 gpt Au and 104 gpt Ag (9.85 gpt Au Eq) including 2.0m grading17.41 gpt Au and 200 gpt Ag (20.08 gpt Au Eq). The Callanquitas structure seems to be getting thicker and high grade along this portion of section NW4780 and remains open at depth. Diamond drill hole CA-17-85 was drilled on Section NW4315 and cut the Callanquitas structure approximately 55 metres vertically above drill hole CA-08-01B (1.6m grading 2.56 gpt Au and 471 gpt Ag, 8.84 gpt Au Eq). These two drill holes help define a northerly raking zone of high silver grades in this portion of the Callanquitas structure, parallel to that seen in the vicinity of drill hole CA-17-86 The zone is open to the North and is unconstrained by drilling at depth, a priority target for resource expansion drilling. Drill hole CA-17-88, drilled on section NW4870, was targeting an undrilled portion of the Callanquitas structure between sections NW4805 and N4990. The drill hole successfully intercepted the Callanquitas structure, 0.4m grading 8.52 gpt Au, 35.2 gpt Ag (9.00 gpt Au Eq), confirming the continuity of gold and silver mineralization in this previously undrilled area. An additional drill hole will be completed on this section to follow up on the results from drill hole CA-17-88.
