Project Overview
Indata is a 4,551-hectare copper-gold-molybdenum-silver porphyry project, with additional unevaluated antimony and nickel mineralization, located 120 km north of Fort St. James, BC, adjacent to the south of Northwest Copper's Kwanika-Stardust property. Access is via an 18-kilometre road originally built by Eastfield in 1996 and since upgraded by logging operators. Eastfield holds a 95.3% interest, with Imperial Metals Corp. holding the remaining 4.7%. The property was previously optioned to Star Copper Corp. (TSX-V: STCU), which commenced diamond drilling in October 2025; 87 drill holes (10,049 metres) have been completed on the property to date. Transaction notice: On June 30, 2026, Eastfield entered into a definitive agreement to sell its 95.3% interest in Indata (Imperial Metals Corp. holds the remaining 4.7%), together with its 100% interest in the Zymo property, to Star Copper Corp. (TSX-V: STCU) for 10.0 million common shares of Star Copper. The transaction constitutes a Reviewable Disposition and a Related Party Transaction and is subject to shareholder approval and TSX Venture Exchange acceptance. The transaction has not closed.
Geology & Target Model
Mineralization is predominantly hosted in an assemblage of andesitic volcanic rocks intruded by a diverse suite of intrusive rocks; both the volcanic and intrusive rocks have been affected by a high-temperature event. Exploration targets include the Lake Zone copper porphyry system at the north end of a 2.4 km coincident IP chargeability and copper-in-soil anomaly, the Area 74 molybdenum-nickel zone, and structurally controlled gold-antimony veins.

Exploration Highlights
- 01
87 diamond drill holes (10,049 metres) completed on the property to date, including 11 holes in 2022 and three in 2025.
- 02
Hole IN22-82 returned 174.0 metres grading 0.23% copper from 2.9 metres (including 29.0 metres grading 0.47% copper), defining the northern boundary of the Lake Zone at the north end of a 2.4 km coincident IP chargeability and copper-in-soil anomaly.
- 03
Area 74 molybdenum discovery (2022): hole IN22-74 intersected 30.8 metres at the bottom of the hole grading 0.102% molybdenum, including 7.5 metres grading 0.320% molybdenum.
- 04
In 2025, hole IN25-87 (Area 74) intersected 107 metres grading 0.14% nickel and 18.0% magnesium, and 24.0 metres grading 15.2 g/t silver, within a serpentinized ultramafic intrusion.
- 05
Historical gold-antimony vein results include hole DDH88-11 with 2.0 metres grading 86.40 g/t gold; bedrock antimony chip samples grade up to 3.80% antimony with 10.40 g/t gold.
- 06
Porphyry copper mineralization is supported by historical trench results of 0.36% copper over 75 metres and 0.20% copper over 148 metres.
- 07
In the northeastern sector of the property, a separate open-ended area (approximately 250 metres north-south) of select grab samples returned high-grade results exceeding 3.0% copper and 0.50 g/t gold, with only minimal follow-up.
