EASTFIELD RESOURCES LTD. TO SELL ZYMO AND INDATA PROPERTIES EASTFIELD TO RECEIVE 10.0 MILLION SHARES OF STAR COPPER

Eastfield Resources Ltd. has signed a definitive agreement to sell its 100-per-cent interest in the Zymo mineral property and its 95.3-per-cent interest in the Indata mineral property to Star Copper Corp. for 10 million shares of Star Copper. Star Copper shares acquired in this transaction will initially be held for investment purposes but may be distributed to shareholders at a later date. Star Copper holds the Star property, a significant copper-gold property in the Stikine region and has a strong corporate structure with a market capitalization of $67.56-million, with approximately $16-million in the treasury.

This transaction constitutes a reviewable disposition by Eastfield and a related-party transaction, and is subject to both shareholder approval and TSX Venture Exchange acceptance.

Zymo property

The 100-per-cent-owned, 18,184-hectare Zymo copper-gold porphyry project is located 45 kilometres west of Smithers, B.C. The property lies along the Skeen Arch, a 160-kilometre-long structural trend that associated with the placement of several porphyry deposits. The property is underlain by Hazelton, Bowser Lake and Skeena lithologies intruded by porphyritic diorite and granodiorite believed to be Cretaceous in age. It was acquired in 2007 through an arm's-length option that was fully satisfied in 2012. In 2024, the claim group was expanded to cover additional airborne geophysical targets. Since acquisition, the company has spent approximately $5-million on exploration. Of major significance is the discovery of an eight-kilometre-long-by-two-kilometre-wide open-ended strong induced polarization anomaly defining a copper-gold porphyry system containing several one-square-kilometre targets with extensive areas having chargeability responses greater than 20 millivolts per volt. Thirty-four drill holes (10,810 metres) have been completed. Mineralization occurs in a porphyritic intrusive and adjacent sediments in zones of strong potassic alteration. Two of the more notable zones discovered to date are the Hobbes and FM zones (five zones in total discovered). Results to date include the following drill intercepts which are provided as examples of the copper-gold endowment.

Peripheral precious metal veins have returned up to 10.78 grams per tonne gold with several per cent lead, zinc and anomalous silver. Topography is generally flat to undulating covered with a variable depth of overburden (generally not deep). Logging roads and clear-cuts now extend to the northeastern side of the property. A valid five-year permit authorizes 50 drill sites.

Indata property

The 95.3-per-cent-owned (Imperial Metals Corp. 4.7 per cent owned) 4,551-hectare Indata copper-gold-molybdenum-silver porphyry project with additional unevaluated antimony and nickel mineralization is located 120 kilometres north of Fort St. James, B.C., and adjacent to the south of Northwest Copper's Kwanika-Stardust property. Indata was previously optioned to Star Copper, which had the right to earn a 60-per-cent interest by completing $2.7-million in exploration and paying $440,000 (cash and/or shares) by Dec. 31, 2027. Eighty-seven drill holes (10,049 metres) have been completed at Indata, of which 11 were completed in 2022 and three in 2025. Results include IN22-82 with 174.0 metres grading 0.23 per cent copper starting at 2.9 metres (including 29.0 metres grading 0.47 per cent copper starting at 2.9 metres). This hole constitutes the northern boundary of the Lake zone, which lies at the northern end of a 2.4-kilometre-long coincident induced polarization chargeability and copper soil anomaly. Mineralization is predominantly hosted in an assemblage of andesitic volcanic rock intruded by a diverse suite of intrusive rocks. Both the volcanic and intrusive rocks have been affected by a high-temperature event. A new zone of molybdenum mineralization was discovered in 2022 five kilometres to the south of the Lake zone, in what is called Area 74, where hole IN22-74 intersected 30.8 metres grading 0.102 per cent molybdenum starting at 113.7 metres and continuing to the bottom of the hole. Results from historical drilling and soil geochemical sampling indicate other significant exploration targets, including gold-antimony veins such as hole DDH88-11, with 2.0 metres grading 86.40 g/t gold. Antimony mineralization in bedrock includes one-metre-wide chip samples grading as high as 3.80 per cent antimony and 10.40 grams per tonne gold.

In 2025, hole IN25-87 (in Area 74) intersected 107 metres grading 0.14 per cent nickel and 18.0 per cent magnesium and 24.0 metres grading 15.2 g/t silver (within a serpentized ultramafic intrusion). Airborne magnetic anomalies outline extensive zones of these intrusions. Indata is fully permitted to 2030.

The transaction is transformative for Eastfield and changes the strategy of advancing and creating value from Zymo and Indata for shareholders from direct physical ownership to indirect equity ownership in Star Copper. At the closing of this transaction, Eastfield's interest in Star Copper will be approximately 14.80 per cent.
