Kirkland Lake Discoveries Announces Uplisting to the OTCQB Venture Market

TORONTO, ONTARIO – March 20, 2026 – Kirkland Lake Discoveries Corp. (TSX-V: KLDC, OTCQB: KLKLF) (“KLDC” or the “Company”) is pleased to announce that its common shares have been approved for uplisting from the OTCID to the OTCQB® Venture Market (the "OTCQB").

The Company’s shares will begin trading on the OTCQB at the market open today under the symbol "KLKLF." The Company’s common shares will continue to trade on the TSX Venture Exchange under the symbol "KLDC."

The OTCQB is recognized by the U.S. Securities and Exchange Commission (SEC) as an established public market and is designed for developing and entrepreneurial companies. To be eligible, companies must be current in their financial reporting, pass a minimum bid price test, and undergo an annual company verification and management certification process.

Strategic Value for U.S. Investors

The uplisting to the OTCQB provides several key advantages for the Company's growing U.S. shareholder base, including:

• Ease of Trading: U.S. investors can now trade KLKLF shares in U.S. Dollars (USD) during U.S. market hours through their preferred online or full-service brokerage.

• Real-Time Transparency: Investors gain access to Real-Time Level 2 Quotes, providing greater price discovery and market depth than previously available on the OTCID.

• Broker Compatibility: As an SEC-recognized "Established Public Market," the OTCQB typically removes restrictions and surcharges often applied by brokerages to lower-tier markets, facilitating broader broker-dealer coverage.

• DTC Eligibility: Enables electronic clearing and settlement, significantly reducing the time and cost associated with trading Canadian-listed securities in the U.S.

“Our move to the OTCQB is specifically designed to bridge the gap for our American investors,” said Stefan Sklepowicz, CEO of Kirkland Lake Discoveries Corp. “By meeting the OTCQB’s rigorous standards for financial reporting and corporate governance, we are providing U.S. investors with the transparency they deserve. This increased accessibility comes at a critical time as we ramp up exploration at our KL West property and integrate the Mirado Gold Project into our portfolio.”

The uplisting follows a series of significant milestones for the Company, including the successful closing of the Mirado Gold Project acquisition earlier this month and the commencement of a 25,000m drill program.
