Indata Drilling add Nickel and Silver to Targets

(TheNewswire)

Vancouver, British Columbia –TheNewswire - January 19, 2026 - Star Copper Corp.(TSX-V: STCU) “Star Copper” and Eastfield Resources Ltd (TSX-V:ETF) “Eastfield” are pleased to report theresults of three diamond drill holes recently completed on the IndataProject located 120 kilometers northwest of the community of FortSaint James, British Columbia. Three holes totaling 532.8 meters weredrilled with two of them in the recently discovered “Area74”.

2025 Drill Hole Details

In 2022, hole IN22-74, drilled in “Area 74”, intersected amineralized biotite-granite which graded 0.102% molybdenum over thebottom 30.8 meters of the hole and ended at 144.5 meters inmineralization still grading 0.04% molybdenum. Hole IN25-87 drilled in the current campaign to adepth of 136.8 meters was a 50 meter step out to the north from holeIN22-74. This hole intersected 106.6 meters of altered ultramafic rockmineralized with nickel and magnesium followed to the bottom of thehole by 23.7 meters of biotite-granite mineralized with copper,molybdenum, silver and antimony. Hole IN25-89, the final hole in thecurrent campaign, was drilled to a depth of 103.1 meters was a 330meter step out to the north from hole IN22-74 and intersected 21.8meters of altered ultramafic rock mineralized with nickel andmagnesium followed to the bottom of the hole by 77.5 meters ofbiotite-granite locally weakly mineralized with gold, silver andantimony. A summary of 2025 results from “Area 74” is as follows:

Area74 Results

The significance of the discovery of nickel andmagnesium mineralization at Indata can be attributed to activity byFirst Point MineralsCorp. who is exploring a new type ofmineralization hosted by serpentinized ultramafic rock at the Decarproperty located approximately 50 kilometers to the south of Indata.At Decar ultramafic rocks have been shown to contain minorconcentrations awaruite (an iron nickel alloy) and traces of highnickel tenor nickel sulfide. In 2011 two float samples similar to theDecar rocks were found at Indata and were subsequently examined usinga scanning electron microscope (Dr. P. Lecouter). The results of the scans (ofall bright metallic domains) indicate an average nickel content of36% and56%respectively for metallic specks in the two float samples suggestingthat the small amount of metallic specks present is most likelynickel-iron alloy (awaruite) or high tenor nickel sulfide. Theultramafic rocks encountered in holes IN25-87 and IN25-89 are similarto the 2011 float samples and consequently may be the source ofthem.

At the Lake Copper target, 5 kilometers to the north,hole IN25-88 was drilled in a northwesterly orientation to elucidatethe mineralized trend encountered in 2022 in hole IN22-82 whichintersected 170.7 meters grading 0.23% copper including 26.0 meters grading0.47% copper. Although returning a narrower intercept than IN22-82 holeIN25-88 has a higher gold to copper ratio suggesting two populationsof copper-gold mineralization may exist. A summary of results fromhole IN25-88 is as follows:

HoleIN25-88 Results

Analyses were performed by MSA LABS of Langley, BCusing ICP multi-element analysis and 30- gram fire assay. Standardsand blanks were inserted by the company and additional samples by thelaboratory and sampling was conducted at approximately 3-metreintervals. Recoveries were generally >85%. Sample results wereverified by comparing results from the standards against their postedvalues. The assay lab completing the work, MSA Labs, is completelyindependent from Star Copper Corp and Eastfield Resources Ltd. Drill core, 4.5 cm in diameter, was cut longitudinallyusing a diamond tipped saw with one half going into the sample bag andone half kept on site for future work.

The Indata property, encompassing 4,551-hectares(11,240-acres), is a copper-gold-silver-molybdenum porphyry prospectwith additional potential for nickel and antimony. It is under optionto Star Copper Corp. who may earn a 60% interest by completing$2,700,000 in exploration and paying $440,000 (cash and/or shares) byDec 31, 2026. Eighty-seven (87) drill holes (10,049 meters) have nowbeen completed at Indata of which 11 were completed in 2022 and 3 in2025. Results include IN22-82 with 174.0 meters grading 0.23% copper startingat 2.9 meters (including 29.0 meters grading 0.47% copper startingat 2.9 meters). A new zone of molybdenum mineralization was discoveredin 2022 five kilometers to the south of the Lake Copper Zone in whatis now called “Area 74” where hole IN22-74 intersected 30.8 metersgrading 0.102%molybdenum (0.16% MoS2 eq.)starting at 113.7 meters and continuing to the bottom of the hole.Results of gold exploration at Indata include hole DDH88-11 with 2.0meters grading 86.40 g/tgold. Antimony mineralization discoveredincidentally in bedrock includes 1-meter chip samples grading up to3.80% antimony and 10.40 g/tgold.
