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 the results of three diamond drill holes recently completed on the Indata Project located 120 kilometers northwest of the community of Fort Saint James, British Columbia. Three holes totaling 532.8 meters were drilled with two of them in the recently discovered "Area 74".

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

Area 74 Results
| Hole Id | From – To (meters) | Intercept (meters) | Element and Value |
| IN25-87 | 6.7-113.1 | 106.6 | nickel 0.14%, magnesium 18.0% |

The significance of the discovery of nickel and magnesium mineralization at Indata can be attributed to activity by First Point Minerals Corp. who is exploring a new type of mineralization hosted by serpentinized ultramafic rock at the Decar property located approximately 50 kilometers to the south of Indata. At Decar ultramafic rocks have been shown to contain minor concentrations awaruite (an iron nickel alloy) and traces of high nickel tenor nickel sulfide. In 2011 two float samples similar to the Decar rocks were found at Indata and were subsequently examined using a scanning electron microscope (Dr. P. Lecouter). The results of the scans (of all bright metallic domains) indicate an average nickel content of 36% and 56% respectively for metallic specks in the two float samples suggesting that the small amount of metallic specks present is most likely nickel-iron alloy (awaruite) or high tenor nickel sulfide. The ultramafic rocks encountered in holes IN25-87 and IN25-89 are similar to the 2011 float samples and consequently may be the source of them.
At the Lake Copper target, 5 kilometers to the north, hole IN25-88 was drilled in a northwesterly orientation to elucidate the mineralized trend encountered in 2022 in hole IN22-82 which intersected 170.7 meters grading 0.23% copper including 26.0 meters grading 0.47% copper. Although returning a narrower intercept than IN22-82 hole IN25-88 has a higher gold to copper ratio suggesting two populations of copper-gold mineralization may exist. A summary of results from hole IN25-88 is as follows:
Hole IN25-88 Results
| Hole Id | From – To (meters) | Intercept (meters) | Element and Value |
| IN25-88 | 20.0-26.0 | 6.0 | 0.42% copper, 0.136 g/t gold |
| 147.0-179.0 | 32.0 | 0.25% copper, 0.023 g/t gold | |
| 224.0-239.0 | 15.0 | 0.13% copper, 0.032 g/t gold | |
| 284.0-290.0 | 6.0 | 0.22% copper, 0.070 g/t gold |
Analyses were performed by MSA LABS of Langley, BC using ICP multi-element analysis and 30- gram fire assay. Standards and blanks were inserted by the company and additional samples by the laboratory and sampling was conducted at approximately 3-metre intervals. Recoveries were generally >85%. Sample results were verified by comparing results from the standards against their posted values. The assay lab completing the work, MSA Labs, is completely independent from Star Copper Corp and Eastfield Resources Ltd. Drill core, 4.5 cm in diameter, was cut longitudinally using a diamond tipped saw with one half going into the sample bag and one half kept on site for future work.
The Indata property, encompassing 4,551-hectares (11,240-acres), is a copper-gold-silver-molybdenum porphyry prospect with additional potential for nickel and antimony. It is under option to Star Copper Corp. who may earn a 60% interest by completing $2,700,000 in exploration and paying $440,000 (cash and/or shares) by Dec 31, 2026. Eighty-seven (87) drill holes (10,049 meters) have now been completed at Indata of which 11 were completed in 2022 and 3 in 2025. Results include IN22-82 with 174.0 meters grading 0.23% copper starting at 2.9 meters (including 29.0 meters grading 0.47% copper starting at 2.9 meters). A new zone of molybdenum mineralization was discovered in 2022 five kilometers to the south of the Lake Copper Zone in what is now called "Area 74" where hole IN22-74 intersected 30.8 meters grading 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 2.0 meters grading 86.40 g/t gold. Antimony mineralization discovered incidentally in bedrock includes 1-meter chip samples grading up to 3.80% antimony and 10.40 g/t gold.
