THE STARPROJECT

NORTHERN BRITISH COLUMBIA

The Golden Triangle is a loosely defined region that hosts a significant amount of major gold, silver and copper deposits in northwestern British Columbia.*

The Star target is an advancing copper-gold system with potential for extension both laterally and at depth. Additional high priority targets, backed by geochemical and geophysical anomalies remain untested and have potential for discovery of new mineralization.

District-Scale Exploration Thesis

Multiple mineralized centres surrounding Star Main

Star Main: established porphyry copper-gold system with a preserved supergene cap and broad hypogene mineralization.
Copper Creek: first modern hole confirmed 111 m of copper-gold mineralization; 2026 follow-up drilling tested larger geophysical targets.
Star North: inaugural drilling confirmed fertile alteration and sulphide vectoring beneath a large IP + Cu-Au soil anomaly; 2026 follow-up completed.
Star East: first-ever drill test completed in 2026 with porphyry-style mineralization logged.
Star West: remains a priority satellite target within the fully funded program.
Working model is a nested / clustered porphyry system; assays and new 3D Induced Polarization (IP) and Magnetotellurics (MT) are intended to test this interpretation.

The Company believes the Star Project has the potential to evolve beyond a single porphyry discovery into a significant copper-gold district within British Columbia’s Golden Triangle.

Our 2026 program has been deliberately structured to accomplish several objectives simultaneously whereby we aim to tighten the drill spacing required to advance Star Main toward a maiden resource, expand the hypogene system to the north and northeast, and build a much more sophisticated three-dimensional understanding of the entire porphyry system through 3D IP and MT.

Darryl Jones, President & CEO

STAR NORTH

The Star North target is located approximately 1000m northeast of the Star porphyry

2025 inaugural 402 m hole confirmed fertile porphyry-style alteration.
2026: hole SN-26-002 completed to 246 m.
2026: Vector toward stronger mineralization within large IP/geochemical target.

From first drill test to 2026 follow-up

Located approximately 1 km northeast of Star Main and defined by a large Cu-Au-in-soil anomaly coincident with strong IP chargeability.
2025 mapping and 119 rock samples included semi-massive chalcopyrite grab samples reported at 17.6% Cu + 0.942 g/t Au and 3.21% Cu.
SN-25-001: first-ever drill hole, 402 m. Assays were modest overall but confirmed intrusive-volcanic architecture, patchy potassic alteration and sulphide-bearing veining consistent with a fertile porphyry environment.
2026 follow-up SN-26-002 completed to 246 m; the Company reported porphyry-style copper mineralization visually and submitted samples for assay.
Follow-up targeting will use assays and integrated geophysics to vector toward stronger parts of the system.

Drilling Snapshot 2025 assay vector + 2026 follow-up

The Star North target mirrors the Star Main target in its geophysical and geochemical signature. Star North boasts a 500m x 1,000m soil anomaly which was used as a vectoring tool for drilling.

STAR EAST

2025:Previously untested satellite;
2026: inaugural hole SE-26-001 completed to 230.6 m with porphyry-style mineralization logged.

COPPER CREEK

The Copper Creek target is the initial (1937) discovery showing on the property

2025: CC-25-001: 111 m @ 0.348% CuEq incl. 57 m @ 0.614% CuEq.
2026: holes CC-26-002/003 completed.
2026: Test broader geophysical system and porphyry source.
Soil and associated geophysical anomalies open to north, south and east.
Extensive malachite-azurite gossans over the area.

Click/tap image to enlarge.

Modern drilling confirms copper-gold mineralization

CC-25-001 was the first modern drill test since 1970s work and confirmed broad structurally controlled copper-gold mineralization.
Mineralization is associated with shearing, brecciation and quartz-epidote-sulphide veining, with chalcopyrite as blebs, disseminations and vein-hosted sulphides.
The target is supported by a 550 m x 1,000 m Cu-Au soil anomaly, IP chargeability and extensive malachite-azurite gossans.
2026 follow-up drilling targeted the larger geophysical system on both sides of the Copper Creek gully.

2026 Follow-Up: Testing scale beyond the 2025 discovery hole

2026 drilling is designed to move from structurally controlled mineralization toward the broader porphyry-style source interpreted from geophysics and geochemistry.
Assays remain the key next data point for evaluating grade, continuity and follow-up priorities.

Copper Creek has the potential to host a significant copper-gold system. Over the past two years we have systematically advanced Copper Creek from a historic occurrence into one of the most compelling targets within the Star district.

Darryl Jones, President & CEO

PYRRHOTITE CREEK

Linear 1800m by 750m altered and mineralized corridor.
High copper in soil anomalies on margin of 1.2 kmIP anomaly.
Historical hand trenching results of 130m @ 0.40 % Cu.

Notably, deep-penetrating IP and MT technologies were instrumental in advancing the geological understanding of the Red Chris Mine, where deeper high-grade mineralization was identified beneath the known deposit, demonstrating the importance of imaging the full vertical extent of porphyry systems.

Darryl Jones, President & CEO

STAR WEST

Priority satellite target with chargeability/geochemical support.
2026: Planned follow-up under 15,000 m campaign.

Star Copper intends to deploy advanced 3D induced polarization (“IP”) and magnetotelluric (“MT”) geophysical surveys to refine the geological and structural model at depth.

Darryl Jones, President & CEO

There are currently no known mineral resources or reserves of historic mining operations on the Property and no known environmental liabilities.
There are no known significant factors that may affect access, title, or the right or ability to perform work on the property.

GEOLOGY

The Star project is an example of an alkalic porphyry copper-gold system.

The regional geological setting comprises island arc volcanic, marine sedimentary, and plutonic rocks of the Middle to Late Triassic Stuhini Group that forms a dominant portion of the accreted geological terrane of Stikinia in the northern Intermontane Belt of the Canadian Cordillera.

In this region, several large Late Triassic calc-alkalic to subalkalic plutons (Stikine suite), including the Kaketsa pluton and Star stock, intrude the Stuhini Group.

Click/tap image to enlarge.

The Kaketsa pluton, in the western part of the property, is about 7 km long by 4.5 km wide at surface, and elongated in the north–south direction.

A separate intrusion of similar age intrudes the Stuhini volcanic rocks in the eastern part of the property.
Numerous dykes occur throughout the property, trending northwest-southeast.
Several faults influence patterns of mineralization and alteration by late mineral and/or post-mineral displacement.

The Star property displays typical porphyry style mineralization in supergene and hypogene settings.

The supergene zone locally extends to between 80-100 m depth and is characterized by disseminated azurite and malachite with fractures coated in tenorite.
Hypogene mineralization at the Star target is defined by vein-hosted and disseminated sulfides (i.e., chalcopyrite, pyrite, bornite, and molybdenite).
Chalcopyrite is volumetrically the most abundant copper sulfide found on the property.

MINERALIZATION

There are three main areas of copper-gold mineralization; the Star (including the Star East and Star North, Copper Creek, and Pyrrhotite Creek zones.

Mineralization is related to zones of intense fracturing near the contact of the Kaketsa and/or related intrusive rocks with the surrounding Stuhini Group volcanic and volcaniclastic rocks, and has many of the characteristics of alkalic porphyry copper-gold mineralization.

Star Main Deposit

The Star stock is a multi-phase intrusion, approx. 500x1000m, comprised of mineralized diorite to tonalite (including qtz-monzodiorites and monzodiorite dykes) and later unmineralized phases of monzonite including crowded pink feldspar porphyry.

The Star Main target is covered by a large, strong, coincident copper-gold soil anomaly that measures 500x500m.

Anomalous gold-in-soil values occur within this area and continue northeast beyond the limits of the copper anomaly.
