Aston Bay Announces 48 Metres of 2.92% Copper Intersected at Storm Project, Nunavut

September 8, 2022

TORONTO, Ontario, September 8, 2022 – Aston Bay Holdings Ltd. (TSXV: BAY) (OTCQB: ATBHF) ("Aston Bay" or the "Company”) is pleased to announce further assay results from drilling 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 an option agreement with Aston Bay in March 2021.


Drill hole ST22-02 has intersected:

  • 48m @ 2.92% copper (Cu) from 8 metres (m) downhole, including;
    • 1m @ 21.9% Cu from 14m downhole, and;
    • 8m @ 7.86% Cu from 29m downhole, including;
      • 3m @ 12.12% Cu from 34m downhole, and;
    • 2m @ 10.24% Cu from 48m downhole
  • Result further confirms continuity of the near surface high-grade copper at the 2750N Zone
  • Further assays for Storm are expected in the coming days.

“These assay results from the 2750N Zone are impressive and again demonstrate the quality of the mineralized system,” stated Thomas Ullrich, CEO of Aston Bay. “These are spectacular copper grades over significant thicknesses very near surface. This increases our confidence in the continuity of the mineralization and confirms the potential to define a shallow copper resource that can support a low cost, small footprint direct shipping product mining operation.

“In addition to moving the 2750N Zone toward development, a compelling discovery story is emerging with the immense potential demonstrated by the intersection of a zone of sediment hosted style of copper mineralization in drill hole ST22-10. Assay results for that hole are still pending, but confirmation of copper would validate our predictive exploration model with significant implications for the potential copper endowment in this region. We eagerly await those results.”

Drill Hole ST22-02 Details

ST22-02 was drilled to a downhole depth of 155m and was designed to test the continuity of the copper mineralization in the central 2750N Zone (Figure 1).

The drill hole intersected a broad, 83m zone of vein and fracture style copper sulfide mineralization from approximately 5m downhole. The volume of copper sulfide throughout the interval is variable and is controlled by the intensity of rock fracturing within the broader fault zone.

The stronger mineralization in ST22-02 (and throughout the 2750N Zone) consists of massive and semi-massive chalcocite and/or bornite and is hosted within large fractures and breccia zones (Table 1 & Figure 2).

The drill core from ST22-02 will be used for beneficiation and metallurgical test work to produce a direct shipping product (DSP) from the 2750N Zone mineralization.

Table 1 summarizes the significant intersections from ST22-02. Intersections are expressed as downhole widths and are interpreted to be approximately 90% of true width. A cut-off grade of 0.5% copper is used to define a significant intersection and is based on ore mineralogy, mineralization habit and expected beneficiation performance.

Drill Hole ST22-01 Details

ST22-01 was drilled from south to north to a downhole depth of 128m and was also designed to test the continuity of the copper mineralization in the central 2750N Zone (Figure 1).

An 18m wide zone of copper mineralization was intersected in ST22-01, which appears to have been part of a much thicker intersection that has been truncated by a high-angle fault (Figure 4).

The preserved copper rich portion of the interval lies on the interpreted footwall of the fault, and appears identical to that in drill hole ST22-02, with massive and breccia sulfides in places over 10% copper. The upper, hanging wall zone of the mineralized interval contains dark grey sooty iron oxides (after pyrite?) and intermittent copper sulfides.

The strong presence of fine grained and sooty pyrite, highly fractured dolomite and weathered nature of the rock package all confirm the presence of a late-stage structure which has likely offset the mineralization on this drill section (Figure 3). Larger examples of these north-south oriented faults can be seen at surface and appear as weathered gullies, one of which is present to the immediate west of the 2750N Zone (Figure 1).

Further drilling either side of this section will define the displacement direction of the typically wide (approx. 50m) zone of mineralization in this part of the mineralized system.

Table 2 summarizes the significant intersections from ST22-01. Intersections are expressed as downhole widths and are interpreted to be approximately 90% of true width. A cut-off grade of 0.5% copper is used to define a significant intersection and is based on copper sulfide mineralogy, mineralization habit and expected beneficiation performance.

2750N Zone: Advancing to a Mineral Resource Estimate

All drill holes completed at the 2750N Zone have successfully intersected thick zones of breccia and/or massive copper sulfides (mostly chalcocite) hosted within much broader intervals of vein and fracture style mineralization.

Of the total of 1,534m drilled during the 2022 program, 997m has been completed at the shallow and high-grade 2750N Zone. The drilling has failed to close off the mineralization, which is over 200m in strike and remains open to the east and west, and at depth. 

There is excellent potential for further extensions to the 2750N Zone with strong copper anomalism in soils and rock chips along strike for over 1km from the known mineralization. Massive chalcocite has been mapped in outcrop to the west of the 2750N Zone, with assays of rock chips up to 62% copper (Figure 5).

Planned Program

Work will continue to progress the near-surface mine development and exploration/discovery paths for the Storm Project in parallel.

Further diamond drilling is planned for next season to expand the shallow, high-grade 2750N Zone, and to define initial resources at the 4100N and 2200N Zones where shallow high-grade copper mineralization has also been intersected in historical drilling.

Exploration activities including drilling and geophysics are also planned for next season to follow-up the significant new discovery of sediment hosted style copper mineralization, which is associated with a large EM anomaly to the west of the previously recognized and highly mineralized 4100N Zone (see August 23, 2022 news release). With six EM anomalies similar to that intersected remaining to be tested, there is strong potential for multiple large-scale mineral system to occur at these deeper levels.

Beneficiation and metallurgical test work will soon commence on the remaining half drill core (ST22-02) from this year’s program. The aim of this work is to create a definitive flow sheet for a direct shipping product operation from the 2750N Zone mineralization. Previous test work on Storm drill core has produced a >53% copper direct shipping product using a full-scale ore sorter and with no further processing or optimization (see April 11, 2022 news release).

Investors can expect further news as the laboratory assays for the remaining drill holes are received over the coming days and weeks.
