OPTEGRA VENTURES ANNOUNCES REINSTATEMENT OF TRADING ON THE TSXV

Vancouver, British Columbia, September 11, 2025 – Optegra Ventures Inc. (the “Company” or “Optegra”) (TSXV: OPTG) announces that the TSX Venture Exchange (the “Exchange”) has accepted the Company’s application for reinstatement of trading in the Company’s common shares (“Common Shares”) on the Exchange, effective on or about September 16, 2025. This follows the successful resolution of the failure-to-file cease trade order (FFCTO) issued by the BCSC on April 2, 2025, and revoked on April 28, 2025.

The FFCTO was issued because of the delay in filing the Company’s annual financial statements for the year ended September 30, 2024 and its interim financial statements for the fiscal quarter ended December 31, 2024, its management’s discussion and analysis for the year ended September 30, 2024 and the fiscal quarter ended December. 31, 2024, and the related filings. The Company filed the required filings on April 25, 2025.

The Company acknowledges and appreciates the patience of its shareholders and stakeholders during this process and reaffirms its commitment to adhering to high standards of compliance and corporate governance.

Exchange Review for Reinstatement

As disclosed in the Company’s audited financial statements for the year ended September 30, 2023, the Company entered into an agreement with Premier Silver Corp. (“Premier”) on September 15, 2022, to provide a US$140,000 convertible loan to Premier (the “Premier Loan”), which included an option for an additional royalty purchase payment up to US$1,000,000 on the Mallay Mine in Peru (the “Royalty Purchase Payment”). The Premier Loan was secured and convertible into common shares for a period of 3 years and accrued interest at a rate of 12% per year and was to form part of the Royalty Purchase Payment. An exclusive 90-day option to negotiate the Royalty Purchase Payment was later extended by 60 days but ultimately expired unexercised. Due to uncertainty of collection, the Company wrote down the Premier Loan receivable in full as of September 30, 2023, being $189,980. At the time the Premier Loan was made, it was intended to be part of a larger transaction with Premier, for which the Company was relying on section 8.1(b) of Exchange Policy 3.2 in respect of any required filings with the Exchange. Ultimately the larger transaction with Premier did not proceed and the Company failed to provide the Exchange with notice of the Premier Loan pursuant to section 8.2(f) of Exchange Policy 3.2. The Company confirms that Premier is an arm’s length party. On July 30, 2025, the Company and Premier entered into a debt settlement agreement (the “Debt Settlement Agreement”) whereby the Premier Loan and all accrued and unpaid interest was settled for (a) common shares in the capital of Excellon Resources Inc. having an aggregate value of $48,250 and (b) the first $48,250 of the stream share revenue received by Premier from the Mallay Mining Unit pursuant to an Agreement of Purchase and Sale between Premier, Adar Mining Corp., and

1267104 B.C. Ltd. The Exchange did not accept the Premier Loan and the Debt Settlement Agreement for filing, and no Exchange approval was provided for these transactions.

Corporate Update

The Company currently has a working capital deficiency of over $900,000 and is actively pursuing debt settlements and financing alternatives to remedy the situation and meet the working capital requirements set out in Exchange Policy 2.5. The Company expects to have the situation resolved in the coming months.

The Company continues to explore joint venture and other opportunities to advance its Mt Turner and Cumberland projects in Queensland Australia.

The Company also continues to investigate additional opportunities where it can advance high-quality exploration and development projects which can be incubated through an option earn-in model without the issuance of vendor shares whenever possible. This strategy has the potential to accelerate the growth in shareholder value for Optegra by earning an interest in a range of projects of merit in a much shorter time frame than otherwise would be possible and allowing Management’s time to be shared across several different projects.
