(TheNewswire)

Vancouver, BC – May 6 th , 2 025 – Eastfield Resources Ltd. ( “ Eastfield ” )(TSX-V: ETF) is pleased to provide an update on recent and upcomingactivities at its Indata and Iron Lake properties, both located inBritish Columbia.

Indata Project (4,551hectares)

The Indata property is located 120 km north of Fort St.James, BC, and is optioned to Star Copper Corp. (formerly Alpha CopperCorp.), which may earn a 60% interest by completing $2.7 million inexploration expenditures and making payments totaling $440,000 (cashand/or shares) by December 31, 2026.

Star Copper recently announced several financingsintended to fund its 2025 exploration programs, including work atIndata (see Star Copper news release dated April 29, 2025). Thisyear ’ s program will focus on drilling forcopper in the Lake Zone and molybdenum in Area 74.

To date, 84 drill holes totaling 9,517 meters have beencompleted at Indata, including 11 holes in 2022. Notable resultsinclude:

- Hole IN22-82: 174.0 meters grading 0.23% copperfrom 2.9 meters depth, including 29.0 meters grading 0.47% copper.This hole defines the northern boundary of the Lake Zone, which alignswith a 2.4 km-long copper-in-soil anomaly.

- Hole IN22-74 (Area 74): 30.8 meters grading 0.101%molybdenum (0.16% MoS ? equivalent) from 113.7meters to the bottom of the hole, including 7.5 meters grading 0.320%molybdenum (0.51% MoS ? equivalent). Area 74lies 5 km south of the Lake Zone and was discovered in 2022.

Historical results include DDH88-11, which returned 4.0meters grading 47.26 g/t gold. Chip sampling in the same area hasreturned values up to 3.80% antimony and 10.40 g/t gold. A valid drillpermit is in place.

Iron Lake Project (8,035hectares)

The Iron Lake property is located 50 km northeast of100 Mile House, BC, within the Triassic – Jurassic Quesnel Terrane. It hosts volcanic, volcaniclastic,and intrusive rocks in contact with a large ultramafic complex severalsquare kilometers in extent.

Eastfield ’ s option partner,Tech-X Resources Inc. (a private company), has earned a 51% interestin Iron Lake by expending $4 million since 2021. Eastfield retains theremaining 49%.

In 2024, Tech-X completed a green rock vectoring studyto target deeper porphyry copper mineralization. Field sampling wasconducted under the supervision of Professor Jamie Wilkinson ofImperial College London. Results are pending and will assist inrefining drill targets.

While previous work at Iron Lake has focused onmineralization related to the ultrabasic complex, the property wasoriginally acquired for its porphyry potential. An inducedpolarization/re sistivity survey completed in2023 outlined multiple untested anomalies. The results of the greenrock study will help prioritize targets within these zones.
