Stellar Project

Stellar Project (100% Owned)

The Stellar Project comprises 231 contiguous State Mining Claims located immediately adjacent to the Company’s Caribou Dome/Senator Copper Project. Together they comprise the Alaska Range Project.

The claims cover a total area of ~150 km² and form a major footprint within the broader Alaska Range Project. Stellar is also currently being aggressively advanced via a US$39 million Joint Venture earn-in agreement with major ASX gold miner Northern Star Resources.

High Grade Gold and Copper at the Zackly Deposit

The high-grade Zackly magnetite Skarn deposit was discovered in 1979. Following transformative validation and step-out drilling programs by PolarX, the resource was upgraded to a JORC Mineral Resource Estimate containing 4.0Mt @ 1.6g/t Au, 1.1% Cu, and 12.6g/t Ag.

The resource is heavily concentrated within the sub-vertical Zackly Main Skarn, which averages a true width of 4–6m and extends over 1,050m in strike length.

Step-out drilling has confirmed that the broader structural system extends over 2.5km of strike length at Zackly East and remains completely open down-dip and along strike. Recent validation mapping continues to yield high grades at surface, including 4.0g/t Au and 2.3% Cu at Zackly.

Thicker, flatter-lying skarn mineralisation has been discovered at the Zackly East Skarn, which holds significant potential for open-pit mining, high-grade gold and copper mineralisation.

The Zackly East Skarn host unit (originally a limestone) was emplaced via thrust faulting and sits in the hanging wall, while the Main Skarn lies below the thrust fault in the footwall.

Both skarns were formed when mineralised fluids derived from the newly modelled 3.5km deeper intrusive source travelled up the fault system and reacted with the limestones.

Under the 2024 Alaska Range Scoping Study, Zackly’s high-grade underground ore is intended to directly follow open-pit feed from Caribou Dome into a centralized 750ktpa flotation mill.

District-Scale Intrusive Target

• 3D magnetic inversion modelling has revealed a massive, deep magnetic anomaly measuring 3.5 kilometres in diameter.
• The Intrusive Core: This deep magmatic system tracks directly north from the Zackly magnetite skarn deposit, sitting beneath the Jupiter prospect and extending toward the Gemini target corridor.
• Surface Validation: High-grade surface copper and gold mineralisation directly overlies several magnetic finger-like offshoots (apophyses) branching upward from this deeper intrusive body. This strongly validates the potential for a large-scale, intrusion-related copper-gold system across the property.

Mars Porphyry Cu-Au-Mo Deposit

The Mars target comprises a large copper-gold-molybdenum-arsenic system defined by a multi-kilometre geochemical footprint and a coincident IP anomaly sitting 100–150m below surface.

• Surface Validation: Recent surface sampling has returned spectacular, ultra-high-grade rock-chip outcrops of mineralised veins and breccias, yielding peak values of 27.3% copper and 1.20g/t gold.
• Strategic Corridor: Mars sits at the critical intersection of a major terrane boundary along the 12km-long WNW corridor linking the Mars, Zackly, and Saturn targets.

Discovery Drill Hole (19MAR001)

PolarX’s deep discovery angled hole reached a final down-hole depth of 417m, intersecting continuous porphyry-style mineralisation from within 6m of the surface to the bottom of the hole. Mineralisation intensity and strongly oxidised, gypsum-dominated fluid alteration increase significantly past 321m depth, indicating close proximity to a hotter, higher-grade core.

Key Mineralised Intersections:

• 308.02m to 410.09m: 102.07m @ 0.22% Cu, 0.07g/t Au, and 20ppm Mo.
  • Including: 36.23m @ 0.26% Cu, 0.08g/t Au, and 43ppm Mo.
  • Including: 28.24m @ 0.28% Cu, 0.09g/t Au, and 52ppm Mo.
