Each unit will consist of one common share of the company and one-half of one common share purchase warrant. Each warrant shall entitle the holder to purchase a common share at a price of 35 cents from the 62nd day after issuance until the date that is 24 months following the closing date (as herein defined).

Offering highlights:

• $5.0-million LIFE financing with Research Capital as exclusive finder;
• Attractive structure: 25 cents per unit with warrant exercisable at 35 cents;
• Immediate liquidity: units issued under the listed issuer financing exemption are expected to be freely tradable;
• Dual-asset advancement: financing to accelerate both the Magno project (British Columbia) and Copecal gold project (Brazil);
• Near-term catalysts: fully financed to execute and expand an approximately 10,000-metre drill program at Magno in 2026;
• Approximately $4.0-million total capital directed toward the Magno project in 2026, including recently completed flow-through financing;
• The company has received strong preliminary interest and is currently building its order book.

Chief executive officer commentary

Rob Birmingham, CEO of Goldhaven, commented: "This financing positions Goldhaven to aggressively advance both of our core assets. At Magno, we are now fully funded to execute and expand a significant 2026 drill program across multiple high-priority zones while continuing to build on the strong initial drilling success at Copecal. We believe this dual-track approach provides shareholders with near-term discovery potential and longer-term growth across two highly prospective districts."

The company intends to use the net proceeds from the offering for the advancement of its Magno project in British Columbia, including permitting, geophysics, drill targeting, and continued and expanded diamond drilling, as well as for continued diamond drilling, follow-up drilling and target advancement at the Copecal gold project in Mato Grosso, Brazil, and for general working capital purposes.

Combined with the company's recently completed flow-through financing, this offering is expected to fully finance and expand the company's 2026 drill program at the Magno project.

Subject to compliance with applicable regulatory requirements and in accordance with National Instrument 45-106 (Prospectus Exemptions), the units will be offered for sale to purchasers resident in Canada, except Quebec, pursuant to the listed issuer financing exemption under Part 5A of NI 45-106. The securities issuable from the offering under the listed issuer financing exemption are expected to be immediately freely tradable in accordance with applicable Canadian securities legislation; however, the warrants will not be exercisable until the 62nd day after issuance.

There is an offering document related to the offering that can be accessed under the company's profile on SEDAR+ and on the company's website. Prospective investors should read this offering document before making an investment decision.
