Vancouver, B.C. – September 4, 2026 – Adelayde Exploration Inc. (ADDY – CSE) (SPMTF – OTC) (A41AGV – WKN) (“Adelayde” or the “Company”) is pleased to announce that its common shares have become eligible for electronic clearing and settlement through the Depository Trust Company (“DTC”). DTC eligibility is expected to simplify the process for U.S.-based brokers and investors to trade and hold shares of the Company electronically.

Highlights

• The Company’s common shares are now eligible for electronic clearing, settlement and custody through DTC in the United States.
• DTC eligibility allows shares to be electronically transferred between brokerage accounts, eliminating the need for physical share certificates and manual transfer procedures.
• The Company expects DTC eligibility to improve trading efficiency, reduce settlement times, and broaden access to Adelayde’s shares for U.S. retail and institutional investors.

“Achieving DTC eligibility is an important milestone for Adelayde,” said James Nelson, President, CEO and Director of Adelayde. “It removes a real barrier for our U.S. shareholders and makes it significantly easier for American investors and brokers to buy and hold our stock. As we advance our antimony, tungsten, and lithium projects in New Brunswick and Nevada, improving accessibility and liquidity for our shareholder base is a priority, and this is a meaningful step in that direction.  We also expect to be drilling on our gold project in Nevada in September giving Adelayde multiple projects that could provide meaningful growth for the Company.  The remainder of 2026 is shaping up to be one of the most active periods in history of Adelayde at a time when gold and commodity prices are showing signs of renewed strength.⁽¹⁾”

Why DTC Eligibility Matters

The Depository Trust Company is a U.S. financial institution that provides clearance, settlement and asset servicing for securities on behalf of its participants, including most major U.S. brokerage firms. When a company’s shares are DTC-eligible, U.S. investors can buy, sell and hold those shares through their existing brokerage accounts in the same electronic, “street name” fashion as shares of U.S.-listed companies — without the delays, costs, or manual paperwork associated with physical share certificates or off-DTC transfers.

For a growth-stage exploration company, DTC eligibility is an important step in building a liquid, accessible shareholder base. It removes a common barrier that U.S. brokers and investors face when considering foreign-listed or OTC securities, can narrow bid-ask spreads by making shares easier to trade, positions the Company to be more easily added to U.S. brokerage platforms and, in time, considered by a broader range of institutional and retail investors. Management views this milestone as a key component of the Company’s broader strategy to strengthen its capital markets profile in the United States.

Vancouver, B.C. – August 28, 2026 – Adelayde Exploration Inc. (ADDY – CSE) (SPMTF – OTC) (A41AGV – WKN) (“Adelayde” or the “Company”) is pleased to announce results from a newly completed airborne magnetic survey and 3D geophysical inversion over its 100%-owned George Lake South Antimony Project (the “Property”) in York County, New Brunswick. The work, completed and interpreted by independent geoscience consultants Geoscience North, has identified multiple discrete, previously untested magnetic targets on the Property that appear to share a similar geophysical signature of the mineralized system at the adjacent, past-producing Lake George antimony-tungsten-molybdenum-gold mine. Management cautions that past results or discoveries on properties in proximity to Adelayde may not necessarily be indicative of the presence of mineralization on the Company’s properties.

Highlights

• A new, high-resolution total magnetic intensity (TMI) survey flown directly over the Property outlines several coherent, discrete magnetic highs within Adelayde’s ground, similar in character and intensity to the anomalies associated with the historic Lake George deposits.
• Three-dimensional magnetic vector inversion (MVI) modelling of the new survey data confirms that these magnetic sources are real, near-surface geological features rather than survey artifacts, and defines their approximate size, depth and orientation for follow-up planning.
• The Property’s magnetic targets sit along the same regional structural corridor, associated with the Magaguadavic Fault trend, that hosts the Lake George mine and other tin-tungsten-antimony occurrences in southwestern New Brunswick.
• The Property lies within the contact metamorphic aureole of the Pokiok Batholith, the same geological setting associated with mineralization at the Lake George deposits, and within the broader footprint of a regionally significant antimony-in-till geochemical trend centred on the Lake George camp.
• None of the newly identified magnetic targets on the Property have been previously drill-tested, representing multiple new, high-priority exploration targets for the Company.

“This new geophysical dataset gives us, for the first time, a clear picture of what lies beneath our George Lake South ground, and it shows several targets we did not know we had,” said James Nelson, President of Adeylade. “Our Property sits directly along strike from a mine that operated intermittently for decades, and these new targets show similar geophysical fingerprints as the mineralized system there. We see this as a strong basis to plan a focused, cost-effective follow-up on our own ground.  We are immediately formulating plans to follow up on this positive news with a more detailed work program with plans to drill as soon as possible.”

About the George Lake South Antimony Project

The George Lake South Antimony Project is located in York County, New Brunswick, immediately southeast of the historic Lake George mine, which was intermittently mined for antimony, tungsten, molybdenum and gold beginning in the early 20th century. The Property covers ground along the same regional geological trend and lies within the contact aureole of the Pokiok Batholith, a setting the Company considers prospective for antimony and related mineralization.

Vancouver, B.C. – May 21, 2026 – Adelayde Exploration Inc. (the “Company” or “Adelayde”) (ADDY-cse) (SPMTF-usa) (A41AGV-wkn) is pleased to announce that the Company has completed two work programs encompassing a helicopter aeromagnetic/radiometric/VLF survey on the Company’s the Sisson North Tungsten Project, and the George Lake South Antimony Tungsten Project, both located in New Brunswick.

James Nelson, President of Adelayde, stated, “We are pleased to be actively advancing work programs across both our Sisson North Tungsten Project and our George Lake South Tungsten Antimony Project as we continue to strengthen our exposure to strategically important critical minerals. Evidenced by strengthening tungsten prices¹, antimony and tungsten have become increasingly important as governments and industries focus on securing reliable domestic supply chains and reducing dependence on foreign sources. With global supply remaining highly concentrated and demand continuing to expand across defense, energy, and advanced technology sectors, we believe these critical materials are positioned to play an increasingly important role in economic and national security. Our geological team is currently underway with reviewing and interpreting the data provided by these two exploration programs. Additionally, we look forward to commencing a gold drill program shortly. Supported by a strong treasury, we remain well financed to aggressively advance our portfolio and generate multiple catalysts across several projects in the months ahead.”

The Sisson North Tungsten Project directly borders the Sisson Tungsten Mine in New Brunswick. On November 13, the Sisson Tungsten Mine was selected by the Prime Minister of Canada, Mark Carney, as one of the first “Nation-Building Projects.” ² Additionally, on August 7, 2025, Northcliff Resources Ltd. announced it secured approximately $29 million CAD in combined funding from the U.S. Department of Defense and the Canadian Government to advance its project. Management cautions that past results or discoveries on properties in proximity to Adelayde may not necessarily be indicative of the presence of mineralization on the Company’s properties.

Sisson North Tungsten Project

Antimony is an essential component in semiconductors and battery storage technology and has several military applications. As trade tensions escalate between China and the United States, where access to raw material units is already tight, restrictions on critical mineral exports from China clearly emphasize the urgent need for Western nations to secure reliable long-term sources of these critical minerals, which are now at the forefront of the global supply chain crisis.
