GRAYCLIFF EXPLORATION UPLISTED TO OTCQB VENTURE MARKET

Graycliff Exploration Ltd. has been approved to uplist from the OTC Pink market to the OTCQB Venture Market, operated by OTC Markets Group Inc. The OTCQB, established in 2010, is the premier U.S. marketplace for early-stage and developing companies. Designed to provide improved visibility and greater access to U.S. investors, the OTCQB is recognized by the U.S. Securities and Exchange Commission as an established public market. The uplisting was effective as of July 7, 2026, and the company will continue to trade under the ticker symbol GRYCF in the United States, with its shares also listed on the Canadian Securities Exchange under GRAY and on the Frankfurt Stock Exchange under GE0.

Graycliff believes this milestone will support increased liquidity, enhance transparency, and attract a broader base of retail and institutional investors in the U.S. capital markets. The company has also submitted an application to The Depository Trust Company to make its common shares eligible for electronic clearing and settlement in the United States. DTC eligibility, once obtained, is expected to simplify the process of trading and transferring the company's securities between brokerage firms, which may enhance liquidity and improve access for U.S. investors.

James Macintosh, chairman of Graycliff, commented: "This uplisting marks an important step in our growth strategy. Trading on the OTCQB Venture Market aligns with our commitment to increasing shareholder value, improving market visibility and maintaining high standards of corporate governance."

The company also announces that it has entered into an advertising and investor awareness campaign with Dig Media Inc. doing business as Investing News Network. INN is a private company headquartered in Vancouver, Canada, dedicated to providing independent news and education to investors since 2007. For the six-month term of the agreement starting July 30, 2026, INN will provide advertising on its website to increase awareness of the issuer. INN does not provide market-making services. The cost of the campaign is $60,000.
