Aston Bay Holdings Ltd. (TSX-V: BAY) (“Aston Bay” or the “Company”) is pleased to announce the results of 2018 drill target generation from its 2017 high-resolution airborne gravity gradiometry survey over the Seal Zinc deposit and prospect. The 2017 survey covered 15,327 line kilometres (km) over the >1,000,000 acre (4,145 km2) Aston Bay Property in the Polaris mining district, Somerset Island, Nunavut. Several significant untested anomalies were identified adjacent to and along strike from the Seal deposit (Figure 1), the subject of this release, and target refinement is ongoing in advance of the planned summer 2018 drill campaign. Significant gravity anomalies spatially associated with high-grade copper mineralization were also identified in the vicinity of the Storm Copper prospect and along a mineralized trend extending 80 km to the south (see November 30, 2017 press release). Analyses of these copper-related anomalies and drill hole target generation will be the subject of an upcoming future press release.

 

Description of Seal and Comparison with Polaris

The Seal Zinc deposit occurs within 200 metres (m) of tidewater and contains a current Inferred Mineral Resource of 1.01 Mt at a grade of 10.24 % zinc (Zn) and 46.5 grams per tonne (g/t) silver (Ag). The deposit is open along strike and at depth. Seal is characterized by stratiform massive and replacive sphalerite-pyrite mineralization within the Lower Ship Point Formation and an associated locally mineralized pseudobreccia in the underlying Turner Cliffs Formation. The style of mineralization and the presence of pseudobreccia are both comparable to the Polaris Mine to the north, which Cominco Ltd. operated for 21 years producing 21 million tonnes ore grading 13.4 % Zn. Although comparable, these features do not necessarily imply that a deposit of the same scale is present at Seal.

The Polaris deposit does not outcrop, and was discovered by Cominco’s drilling of a gravity anomaly north and down-dip of three relatively small zinc showings (Figure 2). Aston Bay has modeled publicly available Polaris gravity data to allow predictive estimation of the scale and magnitude of potential gravity anomalies that may be spatially associated with analogous mineralized bodies at varying depths and sizes.

New Targets Generated by 2017 Gravity Gradiometry Survey at Seal

Aston Bay’s 2017 airborne gravity gradiometry survey provides the first comprehensive gravity coverage of the Seal deposit and its along-strike and down-dip potential. Modeling and inversion of data has identified numerous gravity anomalies along and across strike from the deposit (S12-S16, Figure 3). In addition to an incompletely drill-tested anomaly immediately northwest of Seal (S15), a distinct target (S16) has been identified approximately 600 m along strike northwest of the Seal deposit, where a surface showing returned grab samples of up to 12% Zn. The only previous drill hole in the vicinity, AB95-12, intersected pyritic mineralization at shallow depth.

The Seal deposit is underlain by an over 1 km-long footwall “pseudobreccia” intersected in three widely spaced historical drill holes (Figure 3). One of these holes, 96AB01-29, returned multiple mineralized intervals within the pseudobreccia, including 7% Zn over 1.1 m and 1.5% Zn over 2.2 m core length at the end of a hole. The Seal pseudobreccia is approximately 100 m stratigraphically below the Seal deposit, and closely resembles pseudobreccia present at the Polaris mine. Importantly at Polaris, the pseudobreccia occurs in the same horizon as the orebody as a lateral alteration and mineralization halo. The untested strike and depth extensions of the mineralized pseudobreccia at Seal are therefore considered targets.

The strata host to Seal and the pseudobreccia appear to be fault-repeated across a steep reverse fault immediately east of the deposit (Figure 3). Only one historical drill hole, AB96-18, tested this fault block, and intersected 2.5% Zn over 2.0 m core length in a zone stratigraphically above the target horizon. The gravity survey has identified an untested anomaly (S12) along strike southeast from this hole, approximately 600 m east of Seal. Aston Bay interprets this area to be prospective for fault-offset and/or distinct zones of mineralization outboard of the main Seal target area.

 

Targets at Seal South

The Seal South target area is on a peninsula directly southeast and along strike from the Seal deposit, across a northwest-trending fault (Figures 1, 3, 4). The fault offsets the host strata and also the Seal gravity anomaly, which persists southwards ~2 km along the peninsula (target S12), and is coincident with a 7,000 parts per million (ppm) Zn-in-soil anomaly (Figure 3). There are no previous drill holes in this target.

Further southeast across a normal fault, the gravity survey has identified multiple targets (S1-S11) in the Seal South area (Figure 4). Pseudobreccia in the same stratigraphic position as at Seal has two associated gravity anomalies (S1, S2). Soil samples returned anomalous results of up to 10,600 ppm zinc within the Thumb Mountain Formation host to Polaris, which is underlain by several gravity anomalies including S4, S7, and S8. The four 0.7 to 1.5 km-spaced historical drill holes at Seal South did not test these targets.

Note the presence of mineralization-associated pseudobreccia in the same stratigraphic position as at Seal, and highly zinc-anomalous soil samples.

 

2018 drill program

Aston Bay is planning a drill program to be carried out during the 2018 June-August field season, which will include targeting Polaris-type zinc mineralization at Seal and Seal South. The program will also target high-grade copper mineralization in the vicinity of
Storm Copper and adjacent prospects, where the 2017 gravity gradiometry survey identified significant untested gravity anomalies along strike from known mineralization, which will be the subject of an upcoming press release.
