Aston Bay Announces Drill Targets at Storm Copper

June 21, 2018

Aston Bay Holdings Ltd. (TSX-V: BAY) (“Aston Bay” or the “Company”) 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. (“Gedex”). 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).

Description of Storm Copper

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 (Figure 1). 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.

Storm West Drill Targets

A series of new gravity targets partly coincident with VTEM conductive anomalies have been identified along strike to the west (Storm West, Figure 2) and to the southeast (Storm East, Figure 3) of the Storm mineralization. To the west, four discrete anomalies (SW1-SW4) occur adjacent to the northern fault bounding the Storm graben, along strike from the 4100N zone. These lie partially to completely within a previously identified ~4 km x 2 km VTEM conductive anomaly, where surface soil samples returned anomalous results of up to 221 ppm Cu. Two historical and relatively shallow (~150m) drill holes in the easternmost part of the VTEM anomaly were drilled between the newly defined gravity features (see inset, Figure 2); the remaining areas have not previously been drilled. On the southern flank of the Storm graben, two gravity anomalies (SW5 and SW6) have been identified along strike from the 3500N zone, which, although associated with surface rock and drill core copper mineralization, lacks a significant associated gravity or VTEM anomaly. The eastern of these (SW5) is coincident with soil samples that returned up to 303ppm Cu and has a strike length of ~1km immediately adjacent to the 3500N zone, whereas the western, ~2 km long anomaly (SW6) is subtle and may represent a deeper target.

Storm East Drill Targets

East of the 4100N and 2200N zones, the Storm graben turns southeastwards and has received only limited drilling (Figure 3). Coincident with the change in strike is a ~4 km x 1.5 km VTEM anomaly within which the gravity survey identified three separate anomalies (SE1 to SE3). The northernmost of these (SE1) has associated anomalous Cu values in soil samples (up to 592 ppm); two holes drilled in 2016 were collared to the south of and oriented away from the gravity feature (inset, Figure 3). The other two gravity features within the VTEM anomaly (SE2 and SE3) are untested. Further south, four gravity anomalies lie within the projected trend of the graben (SE4 to SE7, and additional anomalies flank the graben to the east (SE8) and west (SE9 to SE11).

“We are pleased with Gedex’s ability to delineate large, kilometre-scale, near-surface density anomalies from within the broader anomalies defined by the original AGG survey,” stated Thomas Ullrich, CEO of Aston Bay. “These are the priority targets for our summer drill program.”

Dr. David Broughton, Chief Geologist for Aston Bay, commented “We are very encouraged by the success of the gravity survey both in detecting known mineralization as proof-of-concept and in identifying new targets within the prospective Storm graben trend.”


Summer 2018 Drill Program

Mobilization of crew and equipment to the Aston Bay site via Yellowknife and the air base at Resolute has commenced. Approximately 6000 m of drilling is planned for the summer 2018 program. The Company expects to commence drilling before the end of June, initially at the Storm Copper targets and subsequently at Seal Zinc. “The 2018 drill program will soon be underway, and we look forward to updating investors on developments and results as they become available,” remarked Mr. Ullrich. “The Storm Copper and Seal Zinc areas examined thus far represent just 14% of our property on Somerset Island. Targeting continues outside of these areas, and we expect to present additional copper and zinc targets in the coming weeks.”
