Pilley’s Island Project

Overview

The Pilley’s Island Project hosts high-grade VMS mineralization with a rich mining history and strong exploration potential

  • Location

    Consists of 8 mineral licenses encompassing a total land area of 12.25km2 and is located in Notre Dame Bay, Newfoundland – Canada.

  • Accessibility

    Located about 25 km east of Springdale, 210 km from Gander, and 150 km from the Pine Cove Mill and Port. The Project benefits from excellent road accessibility and proximity to key infrastructure.

  • History

    It has a long-established mining history dating to the late 1800s, with about 450,000 tonnes of ore produced by the Pilley’s Island Pyrite Company Ltd., demonstrating significant mineral potential.

  • Volcanogenic Massive Sulfide

    Hosts several Volcanogenic Massive Sulfide (VMS) systems with high-grade zinc, lead, copper, and silver mineralization. Its geological features resemble those of the Buchans camp, indicating strong potential for additional massive sulfide lenses.

Geology and Mineralization

Geology

  • Pilley’s Island is located within the Notre Dame Subzone of the Dunnage Tectonostratigraphic Zone
  • Most of the Project is underlain by Ordovician submarine volcanic rocks of the Roberts Arm Group which is regionally identified as part of a mature arc sequence referred to as the Buchans-Roberts Arm Belt that also hosts the historic Buchan’s mine.
  • Mineralization occurs as low grade (Spencer’s Dock); medium grade (Old Mines); and high grade (3B-Zone/Clifford Jones).
  • The deposits that are of both sub-seafloor replacement and exhalative varieties. The deposits are often flanked by extensive chlorite, sericite, silica, K-feldspar and epidote alteration often observed in bimodal-felsic VMS systems.
  • The Spencer’s Dock area displays sericite/silica alteration that generally increases in intensity near mineralized zones, while the 3B / Old Mine areas display sericite/silica alteration that is abundant but less widespread and is more intense when proximal to mineralized zones.

Mineralization

From north to south this Project is underlain by:

  • Lushes Bight Group – Lower Ordovician

    Composed of pillow basalts, pillow breccias, aquagene tuffs, massive basalt flows, flow breccias, and chlorite schist.

  • Springdale Group – Silurian

    Terrestrial sequence of volcanics, pyroclastics, epiclastic to volcaniclastic sediments.

  • Roberts Arm Group – Middle Ordovician

    The Roberts Arm Group, which hosts known mineralization, is complexly faulted and consist of an older tholeiitic terrane overlain by more calc- alkaline thrust slices. It is suggested that it represents an evolution from tholeiitic, back arc basalts to calc-alkaline intermediate to felsic volcanics deposited at about the time of continental collision in a neritic to littoral environment.

Why VMS (Volcanogenic Massive Sulphide)?

VMS Deposits are Polymetallic, High-grade and Understood Geologically

Polymetallic Revenue Streams

• Copper, zinc, lead, gold, silver (± cobalt) in a single asset
• Diversified exposures reduces reliance on a single commodity and provides a natural hedge against price volatility

High Grades & Strong Economics

• VMS deposits are known for compact footprints with robust grades in copper/zinc
• By-products (gold/silver) lower effective cash costs

Geological Predictability & Camp Scale

• Well-understood geological model; exploration is de-risked
• VMS deposits occur in clusters - one discovery often leads to several

Strategic Alignment

• Supplies critical metals for electrification (copper, zinc, cobalt)
• Governments and majors increasingly prioritizing securing supply, VMS systems are a priority given multiple commodities present

M&A & Exit Potential

• Juniors advance discoveries, natural acquisition targets for mid-tiers/majors
• Track record of premium takeouts in established VMS camps (Noranda, Kidd Creek, Flin Flon, Iberian Pyrite Belt)

Near-Term Exploration Opportunities

  • Further systematic exploration, particularly at depth and along strike of the Clifford Jones/Fragmental Zones is currently being planned

    Many historic programs focused on shallow high-grade showings; deeper targets were only sporadically tested. Deep drilling has confirmed a large hydrothermal system with significant sulfide development. Many historic programs focused on shallow high-grade showings; deeper targets were only sporadically tested.

  • Geophysical anomalies adjacent to known zones were not followed up with drilling

    Jasper Zone intersections (deep sulfides) were recognized but not fully explored with modern vectoring techniques.

  • Consolidate 100+ years of geological information and apply modern exploration techniques

    See Appendix for detailed overview of historic exploration work.

Timing

  • Initial exploration commences in late 2025: MAG + EM survey and 1,500m of drilling to be completed
  • Drilling will be focused on Bull Road target
  • Geophysics will be focused on Bull Road and 3B

Prospective Areas

Bull Road – Clifford Jones Zone / Fragmental Showing

  • The showings at Bull Road are significant, indicating the potential for an ore-grade deposit source, characterized by re-sedimented, polylithic breccia containing abundant high-grade Zn-Pb-Cu sulfide clasts similar to the breccia ores found at Buchans.
  • The Bull Road showing describes a steeply dipping tabular volcanic breccia with high concentrations of copper, lead, zinc, and silver and features massive sulphide clasts.
  • Trenching conducted by Great Atlantic Resources Corp. and Unity Resources Inc. exposed significant sulfide mineralization trending northwest-southeast over a length of approximately 200.00 meters with mineralization varying in width between 1.00 – 7.00 meters.
  • This would be completed by interpretation of existing geophysics and rock outcrops with extensive new trenching as to better explain location geology and structure.
  • More detailed and relevant geophysics and possible downhole probing to be conducted as to better understand the geology and possible modeling.
  • The best results from channel sampling (over 1.05 meters) from the trench include:
    • 1.05 meters returned grades of 15.40% Zn, 6.60% Pb, 4.66% Cu, 111.50 g/t Ag
    • 0.70 meters returned grades of 17.30% Zn, 0.10% Pb, 2.97% Cu, 31.20 g/t Ag
    • The best results from bedrock grab samples from the trench returned up to 40.8% Zn, 20.0% Pb, 8.36% Cu, 148.1 g/t Ag, 2.28 g/t Au
  • Recent exploration and sampling have provided updated data, indicating a continuation of substantial mineralization within the project area which shows stack sequences of the debris flow which warrants detailed remapping.
