STAR COPPER ANNOUNCES CLOSING OF OVERSUBSCRIBED FLOW-THROUGH SHARE PRIVATE PLACEMENT

Star Copper Corp., further to its news releases dated Feb. 17, 2026, and March 3, 2026, has closed its non-brokered private placement for gross proceeds of $7,306,000 from the sale of 5,844,800 flow-through (FT) shares of the company at a price of $1.25 per FT share. Due to investor demand, the company further upsized the offering for additional gross proceeds of $1,306,000 from the sale of an additional 1,044,800 FT shares. The FT shares were issued as flow-through shares, as defined in Subsection 66(15) of the Income Tax Act (Canada).

The gross proceeds from the offering will be used to incur Canadian exploration expenses that are flow-through critical mineral mining expenditures, within the meaning of the tax act, on the company's flagship Star project in British Columbia. The company expects the flow-through funds to directly support an aggressive 2026 drill program, including expanded stepout drilling, deeper testing of priority targets and follow-up drilling, guided by continuing three-dimensional geological modelling and planned deep-penetrating 3-D geophysics.

The company paid cash finders' fees in connection with subscriptions to the offering totalling $420,332.50. All securities issued under the offering have a hold period of four months and a day from the date of issuance.

The company's private placement of charity flow-through units is continuing as announced on March 3, 2026.

Star Copper is an exploration and development company focused on developing high-potential copper projects in mining-friendly jurisdictions. The company aims to advance its 100-per-cent-owned Star project in British Columbia's prolific Golden Triangle and Sheslay district. The project hosts multiple copper-gold porphyry-style targets, including Star Main, Star North and Copper Creek.

The company further plans to advance its Indata project with follow-up drilling to expand on previous high-grade copper and gold intercepts, trenching and surface sampling to delineate mineralized zones, and infrastructure improvements for site accessibility and operations. With a commitment to sustainable development and value creation, Star Copper aims to position itself to support surging industrial demand to meet growing global electrification needs.
