GREGORY RIVER

OVERVIEW

Gregory River provides a unique opportunity to explore for critical minerals in a highly prospective part of Newfoundland that has been largely overlooked and today remains underexplored. The 100%-owned property is centered on an 11-km stretch of the Gregory River volcanogenic massive sulphide (“VMS”) target corridor that hosts several copper ± gold-zinc-silver VMS prospects, as well as a cluster of high-grade copper + gold veins.

Several campaigns of early-stage exploration by Golden Spike between 2022 and 2024 have significantly enhanced the potential of the Property and built the framework for New Discoveries. 

HISTORICAL WORK

  • 1920s: Copper-rich veins first discovered at Gregory River.
  • 1920s – 1950s: High-grade, vein-type, copper-gold prospects discovered at Court A, Hall, Palmer and Mitchell. Short exploration adits completed at Palmer and Mitchell.
  • 1950s: 28 shallow core holes (<100 m average length) drilled at Court A (17 holes) and Hall/Palmer (11 holes) targeting Cu-Au veins. 
  • 1980s – 1990s: Exploration focused on VMS mineralization along the Gregory River VMS-corridor; prospects discovered at Gregory River, Lode 9, Camp Brook/Moose Brook*, Steep Brook and others.
  • 1984 - 2006: 8 shallow core holes** (~109 m average) test VMS targets at; Camp Brook/Moose Brook (4 holes*), Lode 9 (3 holes) and Steep Brook (1 holes). 
  • 1920s – 2023s: Several hundred rock samples collected, many with high-grade copper and gold values returned, along with anomalous zinc and silver; historical soil surveys over selected target areas – most of the rock and soil anomalies never followed up. 
  • 2023 – August 2024: July 2022, Golden Spike acquires Gregory River and complete land acquisition, prospecting, sampling, soil sampling, and IP.
  • October - December 2024: inaugural Golden Spike drill program.

COPPER & GOLD POTENTIAL

Cyprus-type VMS Targets

The Gregory River VMS Target Corridor is an approximately 11 km long, underexplored trend with only 8 historical drill holes reaching target depth. It is prospective for Cyprus-type VMS deposits, which in Canada typically average over 3% copper and around 2.5 g/t gold. The area hosts multiple VMS targets, including Lode 9, Steep Brook, Camp Brook/Moose Brook, Gregory River, Jumbo South, and Deep Brook. Historical and recent surface samples show high-grade mineralization, averaging approximately 1.75% copper and 0.76 g/t gold, with values reaching as high as 19.6% copper and 27.4 g/t gold. In 2024, exploration activities including IP surveys and diamond drilling were completed at Steep Brook and Lode 9, resulting in the discovery of new mineralized zones.

Vein Targets

The Vein Zone is located in the northeast quadrant of the property and comprised of a series of south-easterly to north-easterly-trending high-grade copper mineralized veins and structures, including the Hall, Palmer, Lodes 6 & 7, Court A, B, & C and Mitchell prospects. These sulphide-rich veins are generally 0.5 metres to 2 metres in width, but locally as wide as 5 to 6 meters. Historical surface sampling, diamond drilling and two underground exploration adits have traced these structures for distances ranging from several meters to more than 350 metres along strike, along which copper grades generally average around 2% to 5% but are often in excess of 10% copper. Most of the target area is covered by a thin veneer of soil and there is excellent potential to extend the length of the known structures and to discover new veins.

Geology

The property is situated within the Lower Ordovician Bay of Islands Ophiolite Complex and is underlain by a north-northeast trending sequence of ultramafic to mafic intrusive rocks, basaltic lavas, and narrow sedimentary zones. This same ophiolitic complex hosts the York Harbour VMS deposit, located 27 km to the south. A broad, gently plunging, north-northeast trending synform is interpreted to run through the southern part of the property, accompanied by local anticlinal fold pairs and potentially extending further north. The north-northeast trending Gregory River Fault transects the western portion of the property, along with numerous associated fault splays and localized zones of shearing and brecciation. Many of the VMS and lode-style prospects on the property appear to be spatially associated with these structures. The VMS-style prospects at Gregory River are interpreted to be Cyprus-type deposits, primarily hosted within basaltic units near their contact with gabbro.

*Mineralization at York Harbour is hosted on an adjacent property and is not necessarily indicative of mineralization hosted on the Company’s Property.

VMS-STYLE MINERALIZATION

(Cu ± Au Zn Ag)

Multiple VMS prospects have been identified along the Gregory River VMS Corridor, which are hosted in basalt near the contact with gabbro and are spatially associated with the Gregory River Fault. The mineralization is stratabound and fracture/veinlet-hosted, comprising disseminated to massive pyrite, chalcopyrite ± bornite, chalcocite, covellite, and sphalerite. The main VMS targets include Steep Brook, Lode 9, Gregory River, Moose Brook/Camp Brook*, Jumbo South, and Rusty Brook. Historical drilling has been limited, with 8 of 11 drill holes successfully reaching target depth—several yielded significant intercepts, but no historical follow-up was conducted. In 2024, Golden Spike initiated reconnaissance drilling, completing 3 holes (654 m) at Lode 9 and 5 holes (921 m) at Steep Brook, intersecting numerous anomalous intervals.

*The Camp Brook/Moose Brook prospect straddles the west boundary of one of the licences on the Property and portions of the mineralization may occur on an adjacent property. Insufficient drilling has been done to estimate the true widths of the drilled intervals. None of the historical core from Lode 9 and Camp Brook/Moose Brook has been kept and the QP is unable to validate these historical drill results. However, recent surface sampling corresponds with the general grades reported from these earlier drilling campaigns and the QP feels that it is reasonable to report these results as historical, as they provide a useful guide for future exploration. A portion of Steep Brook hole CC-2 was re-sampled by the Company returning copper values in a similar range.

Historical Drill Results

  • Lode 9: 0.93% Cu, 0.27 g/t Au over 20.2 m (1991 Noranda hole 91-2, 38.0 - 58.2 m), including 2.12% Cu and 0.60 g/t Au over 7.2 m (51.0 - 58.2 m)
  • Steep Brook: 0.12% Cu over 65.6 m (1984 Duval hole CC-2, 70.6 - 136.2 m), including 0.37% copper over 3.4 m (80.0 - 83.4 m)
  • Camp Brook/Moose Brook*: 0.33% Cu, 0.45% Zn, 0.54 g/t Au over 21.0 m (2005 Playfair hole GGR-06-04, 5.8 - 28.8 m), including 0.78% Cu, 1.05% Zn and 1.19 g/t Au over 8.3 m (6.3 - 14.6 m)

LODE 9 VMS TARGET

(Cu ± Au Zn Ag)

Golden Spike completed an IP Survey (2023), revealing several subparallel anomaly trends, one coinciding with the Lode 9 Prospect.  Follow-on exploration included three diamond drill holes:

  • DDH GR-24-006: drilled 50 m below the Lode 9 Prospect, and 25 m below Noranda hole GR-91-2, intersecting 2 zones of copper-gold mineralization:
    • 1.49% copper, 0.45 g/t gold over 2.88 m including, 2.40% copper, 0.67 g/t gold over 1.56 m and 4.63% copper, 1.24 g/t gold over 0.56 m
    • 0.34% copper, 0.18 g/t gold over 9.43 m (Lode 9 Zone) including 1.49% copper, 0.34g/t gold over 0.5m and 0.99% copper, 0.85 g/t gold over 0.75 m
  • DDH GR-24-007: tested a subparallel IP anomaly to the west intersecting several zones of anomalous zinc +/- copper mineralization, suggesting the possibility of stacked horizons and metal zoning. 
  • DDH GR-24-008: remained in footwall gabbro, only intersecting minor anomalous mineralization.

Historical core from Lode 9 has not been kept and the QP is unable to validate this historical drill hole and the historical sampling. However, the companies that completed the historical work were large, reputable companies that would have had sampling and quality control processes in place that were considered industry standard for the time.  Insufficient drilling has been completed to determine true width of the mineralization intersected in the drill hole.

STEEP BROOK VMS TARGET

(Cu-Au-Zn)

Golden Spike completed an IP Survey (2023), revealing several anomaly trends coinciding with historical soil and rock sampling anomalies. Five reconnaissance drill holes completed during 2024 totaling 921 m tested five different IP anomalies supported by geological interpretations, soil results and rock sampling. Each drill hole returned anomalous results, highlighted by: 

  • 0.33% copper, 0.04 g/t gold over 11.15 m (hole GR-24-003, 69.85m to 81.0 m)
    • including, 1.29% copper, 0.19 g/t gold over 1.50 m (69.85m to 71.35m)
    • and 1.37% copper, 0.02 g/t gold over 0.50 m (79.0m to 79.5m)  (new bullet here)
  • 0.40% copper, 0.08 g/t gold over 11.0 m (hole GR-24-005, 19.0m to 30.0m)
    • including, 1.26% copper, 0.11 g/t gold over 1.47 m (27.27m to 28.75m)

Drilling confirms Golden Spike’s VMS target concept and that wide zones (>10 m drilled width) with higher grade intervals (>1.0% Cu) exist at Steep Brook. Next steps will be to interpret the layers of data to vector into areas where mineralization could be wider and higher in grade.

VEIN-STYLE MINERALIZATION

(Cu-Au)

Vein Zone

The area hosts a cluster of east-trending, high-grade quartz-carbonate-sulphide veins. These veins typically range from approximately 0.5 m to 2 m in width, locally expanding up to 5 m to 6 m, and contain fracture-hosted and semi-massive to massive sulphides with copper content ranging from about 1% to 25%, averaging roughly 2% to 6%. Historical sampling did not consistently test for gold or other metals, but recent surface sampling indicates potential gold values between 0.1 g/t and 3 g/t. The Court A vein was historically tested by 17 shallow core holes drilled in the 1950s, tracing the vein approximately 340 m northwest, down to vertical depths of around 50 m, with veins remaining open in all directions. Historical drillhole sampling was limited to only the highest-grade portions of the veins (two or three assays per hole), leaving much of the surrounding host rock unsampled. Potential exists for wider mineralized haloes surrounding the main veins and for discovering new veins hidden below surface soil and till cover. To test this concept, Golden Spike completed soil sampling, rock sampling, IP, and two diamond drill holes. Selected historical down-hole intercepts at Court A include (note: gold was not analysed):

  • Hole 1: 2.13% Cu over 6.1 m from 90.5 to 96.6 m
  • Hole 5: 4.71% Cu over 1.8 m from 94.2 to 96.0 m
  • Hole 6: 4.65% Cu over 1.5 m from 71.3 to 72.8 m
  • Hole 10: 9.60% Cu over 2.7 m from 76.2 to 78.9 m
  • Hole 13: 4.81% Cu over 1.2 m from 74.4 to 75.6 m

Golden Spike soil sampling revealed several ENE-trending copper anomalies greater than 90 ppm (up to 1,080 ppm), extending up to 1,500 m in length and 50 to 150 m in width. These anomalies coincide with the Court A, B, and C Prospects and continue for considerable distances across soil-covered areas that have no previously documented exploration. Three wide-spaced, north-south IP lines completed in 2024 identified numerous first and second priority IP anomalies, several of which align with soil anomalies and known Prospects. Drill hole DDH GR-24-009 tested the Court C IP anomaly and intersected approximately 40 meters of chlorite-altered gabbro containing 1-15% disseminated and fracture or veinlet-hosted pyrite ± chalcopyrite, coincident with the IP chargeability high. Within this alteration, a roughly 5.95 m interval assayed 0.27% copper (76.05-82.0 m), and further downhole, a 0.5 m section returned 1.25% copper (93.8-94.3 m). Drill hole DDH GR-24-010 had no significant results, but may have been collared too far south.

2024 DRILLING HIGHLIGHTS

Wide-spaced, reconnaissance drilling results support Golden Spike’s exploration concept for VMS mineralization at Gregory River. Drilling in the Vein Zone has demonstrated the potential for wider zones of copper mineralization. Numerous high-priority IP anomalies remain untested at both the VMS and Vein Zone targets. The next steps involve the integration and technical analysis of drill results, combined with surface geochemistry, field mapping, and geophysics, to develop vectors towards wider and higher-grade mineralization, identify new exploration targets, and ultimately conduct additional drilling.

2024 EXPLORATION SUMMARY

  • IP/Resistivity survey: 11-line km over the Steep Brook and 4.5 line-km over the Vein Zone.
  • Rock sampling: Steep Brook and other regional targets.
  • In-Fill Soil Sampling: over crucial data gaps at the Vein Zone.
  • IP Modeling and Drill Target Generation: Covering Steep Brook, Lode 9 and Vein Zone. 
  • First Pass Diamond Drilling: 10 wide-spaced holes, totaling 1,927m testing Steep Brook, Lode 9 and the Vein Zone.
  • Strong copper+/-gold-zinc anomalies returned from most drill holes. Results are being further interpreted and follow up drilling is warranted. Many high priority IP anomalies remain untested.
  • Lode 9 is open at depth and along strike.
  • Steep Brook drilling has intersected several new anomalous zones that remain open in all directions.
  • Vein Zone drilling at Court C has revealed a wide halo of alteration and anomalous copper mineralization coincident with IP chargeability; only two drill holes have tested the many High Priority IP anomalies.

2025 EXPLORATION PLANS

  • Soil Sampling: Steep Brook North and South Targets, both being prime VMS target areas that have never been thoroughly explored.
  • Prospecting, Sampling, Mapping: Continued property-wide prospecting and sampling to develop a base for future targeting. 
  • Diamond Drilling: Following up on the 2024 drill results and continuing to test priority IP anomalies
