Aston Bay Holdings Ltd. is pleased to announce additional results of targeting at its 100% owned Aston Bay Property. Based on modeling and inversion of the >15,000 line-kilometre (km) airborne gravity gradiometry (AGG) survey flown in 2017, and integration with existing VTEM, geochemical and geological datasets, the company has generated multiple priority drill targets at the Storm Copper prospect for testing during the summer drill program. Reprocessing and modeling of the AGG data was performed by geophysicists at Gedex Systems Inc. Storm Copper lies within the Company’s >1,000,000 acre (4,145 km2) Aston Bay Property in the Polaris Mining District, Somerset Island, Nunavut. Drill targets were previously announced for the Seal Zinc deposit and surrounds (see the Company’s news release dated May 31, 2018). The Storm Copper prospect contains high-grade copper mineralization hosted in gently dipping Paleozoic carbonate rocks, along and adjacent to the northern and southern margins of a west-northwest to east-northeast trending, ~1 km wide, fault-bounded valley or graben. The mineralization is constrained by geochronological dating as part of a regional copper and zinc mineralization event that also formed the past-producing (21 Mt at 13.4% Zn (Dewey et al., 2007)) Polaris mine, and by analogy, the Seal Zinc deposit. At Storm, disseminated and fracture-controlled chalcocite is present over a strike length of >4 km at the sub-cropping, 2200N, 2750N and 3500N and sub-surface 4100N zones. Highlights from previous drilling are shown in the accompanying Table 1, and include 32.8m grading 5.40% Cu (ST97-08), 24.6m grading 6.17% Cu (ST99-19) and, most recently, 8.0m grading 5.45% Cu (STOR1601D). The 2017 gravity survey detected anomalies coincident with known zones of mineralization and identified additional anomalies beyond the previous limits of drilling.
