Aston Bay Announces Thick Intersections of Copper Mineralization in Initial Drillholes at Storm Project, Nunavut

TORONTO, ON / ACCESSWIRE / July 25, 2022 / Aston Bay Holdings Ltd. (TSXV:BAY) (OTCQB:ATBHF) (“Aston Bay” or the “Company”) is pleased to announce the excellent visual results confirming the presence of copper mineralization for the first two drill holes completed at the Company’s high-grade Storm Copper Project (“Storm” or the “Project”) on Somerset Island, Nunavut. This is the maiden drilling program for American West Metals Limited (“American West”), who are the project operator, since entering the option agreement with Aston Bay in March 2021.


  • Visual geological observations of the first two diamond drill holes at the high-grade Storm Copper Project indicate that both holes have intersected extensive copper sulfide mineralization near-surface;
  • ST22-01 has intersected 72.1metres (m) core length of mineralization including 23.74m core length of breccia and massive copper sulfides over multiple intervals;
  • ST22-02 has intersected 81.22m core length of mineralization including 22. core length of breccia and massive copper sulfides over multiple intervals;
  • Drilling at Storm continues with an additional 15-20 diamond drill holes planned to test priority high-grade copper targets, including a number of new electromagnetic (EM) conductors that have the potential to deliver new sulfide copper discoveries; and
  • Shallow high-grade copper mineralization at Storm has the potential to support a low-footprint direct shipping product (DSP) operation.

“Drilling at Storm has produced outstanding results in the initial two drill holes, with over 72m of dominantly chalcocite mineralization visible in the core from drill hole ST22-01 and over 81m of similar mineralization visible in ST22-02,” stated Thomas Ullrich, CEO of Aston Bay. “These are significant results and demonstrate the continuity between historical copper intersections at the 2750N Zone, where our partners are working to define a copper resource. Previous ore sorting test work has demonstrated that the area can produce a high-value >53% copper direct ship product, highlighting the potential to support a low cost and low footprint direct ship mining development option.”

Drill holes ST22-01 and ST22-02 have successfully intersected thick zones of breccia with locally narrow zones of semi massive to massive chalcocite (copper sulfide) hosted within much broader intervals of vein and fracture style copper mineralization. Laboratory assays are pending and required to confirm the copper content in the drill core.

The drill holes are part of the extensional and resource definition drilling program for the 2750N Zone where historical drilling has encountered significant copper mineralization, including 110m core length at 2.45% copper (Cu) from surface (drill hole ST97-08), and 56.3m core length @ 3.07% Cu from 12.2m (drill hole ST99-19). Significantly, the 2750N Zone copper mineralization remains open at depth and along strike with further drilling planned.

The results from ST22-01 and ST22-02 confirm the continuity of the near-surface mineralization in this area and provide strong support for the potential to delineate a shallow, high-grade resource at the 2750N Zone.

The 2750N Zone is the focus of initial resource work to define resources for a potential open-pit direct shipping product (DSP) mining operation. Initial ore sorting test work on mineralization from Storm generated a DSP product grading more than 53% Cu (see news release dated April 11, 2022).

The combination of high-grade and shallow mineralization at Storm provides a potential pathway to a very low footprint, ESG sensitive mining operation scenario with the potential for low initial capital and operating costs.

ST22-01 is the first hole to be completed as part of the 2022 program and was drilled to a downhole depth of 128m.

The drill hole was designed to test the continuity of thick mineralization intersected in historical drill holes ST97-08 and ST99-19. These two historical drill holes are situated approximately 100m apart (Figure 3).

ST22-01 intersected over 72.1m of chalcocite and chalcopyrite mineralization hosted within dolomite of the Allen Bay Formation. This host unit is present throughout the Storm Project area and is comprised of massive-to-thinly bedded dolomicrites (dolomitized limestone).

The mineralization encountered within ST22-01 is comprised of six zones of breccia to massive sulfides hosted within a broad mineralized package of mostly vein and fracture style mineralization. Fracturing and sulfide mineralization are likely controlled by graben formation, which is interpreted to be located immediately south of the 2750N Zone.

The dominant copper mineral observed within ST22-01 is chalcocite, with minor local chalcopyrite and other copper sulfide minerals.

Chalcocite is an important copper mineral due to its high copper content (79.8% copper) and favorable metallurgical properties. The simple mineralogy of the Storm mineralization is a further feature that makes it amenable to producing a high-grade direct shipping product.

Mineralization as observed in ST22-01 is summarized in Table 1. Intersections are expressed as downhole widths and are interpreted to be close to true widths. Visual estimates of sulfide quantity and habit should not be considered a substitute for laboratory assays.

ST22-02 was drilled to a downhole depth of 155m. The drill hole was also designed to test the continuity of mineralization between drill holes ST97-08 and ST99-19.

ST22-02 has intersected similar geology and mineralization to that of ST22-01, suggesting continuity of the main ore zone.

Drilling Continues

The diamond drilling is continuing at the 2750N Zone with drill holes now targeting eastern extensions to the mineralization.

Preparations are also underway for drill testing a number of high-priority EM conductors that were identified by the 2021 fixed loop electromagnetic (FLEM) survey within the Storm Project area.
