STAR COPPER ANNOUNCES CLOSING OF CHARITY FLOW-THROUGH UNIT PRIVATE PLACEMENT

Further to the news releases dated March 3, 2026, Star Copper Corp. has closed its non-brokered private placement for gross proceeds of $2,000,001.10 from the sale of 1,156,070 flow-through units of the company at a price of $1.73 per FT unit to charitable purchasers.

Each FT unit is composed of one flow-through common share issued as a flow-through share, as defined in Subsection 66(15) of the Income Tax Act (Canada), and one transferable common share purchase warrant. Each warrant also qualifies as a flow-through share (as defined in Subsection 66(15) of the tax act). Each warrant entitles the holder to purchase one non-flow-through common share of the company for a period of two years at a price of $1.75 per warrant share.

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 3-D geological modelling and planned deep-penetrating 3-D geophysics.

All securities issued under the offering have a hold period of four months and a day from the date of issuance.
