VANCOUVER, BC, May 29, 2026 – Adelayde Exploration Inc (ADDY:CSE, SPMTF:USA, A41AGV:WKN) (the “Company” or “Adelayde”) wishes to announce that it has elected to rely on Coordinated Blanket Order 51-933 Exemptions to Permit Semi-Annual Reporting for Certain Venture Issuers (the “Blanket Order“) and move to semi-annual financial reporting.

James Nelson, President of Adelayde Exploration Inc., stated, “Transitioning to semiannual reporting reflects our continued commitment to operating efficiently while maintaining a strong focus on advancing our projects and creating shareholder value. At the same time, we are expanding our market presence through the engagement of a Europe-focused marketing initiative as we prepare for what management believes will be one of the busiest and most transformative periods for the Company in recent years. With multiple exploration programs expected to commence in the near-term, we believe the Company is entering an exciting new phase of growth and activity across our portfolio.”

The Blanket Order permits eligible venture issuers to voluntarily move from quarterly to semi-annual financial reporting. The Company has determined that it meets the eligibility criteria under the Blanket Order, including that it is a venture issuer listing on the Canadian Securities Exchange (the “CSE”), has annual revenue of less than $10 million, and has a clean 12-month continuous disclosure record.

Under the Blanket Order, the Company will be exempt from filing interim financial reports and related management’s discussion & analysis (“MD&A”) for its first and third quarters. The Company’s fiscal year ends on January 31. The initial period for which the Company will not file an interim financial report and related MD&A in reliance of the Quarterly Reporting Exemption will be for the three-month period ended April 30, 2026. The Company will continue to file its audited annual financial report and related MD&A (due within 120 days of January 31) and six-month interim financial report and related MD&A (due within 60 days of July 31).

This news release is being filed pursuant to the Blanket Order.

Adelayde also wishes to announce it has engaged Dr. Reuter Resources GmbH (“Dr. Reuter“) to provide investor relations services to Adelayde (the “IR Agreement“). The IR Agreement, which was executed on May 26, 2026 (the “Execution Date”), has a term of six months effective on the Execution Date, and has a three-month review period whereby this IR Agreement can be terminated by either party within 14 days of this date with no penalty.

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.

Vancouver, B.C. – February 27, 2026 – Adelayde Exploration Inc. (the “Company” or “Adelayde”) (ADDY-cse) (SPMTF-usa) (A41AGV-wkn) is pleased to announce that the Company has engaged New-Sense Geophysics Ltd. (“NSG”) of Markham, Ontario, for a work program encompassing a helicopter aeromagnetic/radiometric/VLF survey on the Company’s Sisson North tungsten project in New Brunswick.

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.”⁽¹⁾ 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.

James Nelson, President of Adelayde, stated, “The Company is well financed and excited to be hiring a geological team with experience in New Brunswick, as we begin working on the Sisson North Tungsten Project. Critical minerals, and tungsten in particular, have received increased attention in recent years as governments and industry seek to strengthen domestic supply chains and reduce reliance on foreign sources. Critical minerals are increasingly important as supply chains remain highly concentrated and demand continues to grow across defense, energy, and advanced technology sectors. This environment, as well as the rising price of tungsten ⁽²⁾, is driving renewed focus on domestic exploration and development.” James Nelson went on to say, “In addition, according to tradingeconomics.com, lithium prices have nearly tripled since June 2025 and the Company recently entered into a joint-venture agreement to explore the deepest sections of the only lithium brine basin with production in North America located in Clayton Valley, Nevada, directly bordering and completely surrounded by energy giant SLB (formerly Schlumberger). We look forward to a very active start to 2026 as the Company is well financed to execute multiple planned exploration and work programs, with multiple chances for exploration success.”

Adelayde recently announced (January 28, 2026) it entered into a joint venture agreement (“JV”) to explore the deep basin lithium brine potential in Clayton Valley, Nevada. The 115 mineral claims comprising the 2,300-acre JV land package are all located within, and completely surrounded by, SLB’s (formerly Schlumberger) and Pure Energy Minerals’ Lithium Deposit (see map below). Clayton Valley, Nevada is the only long-established producing lithium brine basin in the U.S., home to Albemarle’s Silver Peak lithium brine mine, which extracts lithium from subsurface brines. It has been the sole U.S. producing lithium brine operation since the 1960’s.

Adelayde recently announced (January 22, 2026) that it has joined the National Defense Industrial Association (NDIA) in support of the advancement of its critical and strategic mineral portfolio. The NDIA is a U.S.-based organization promoting national security by connecting industry and government.

Vancouver, B.C. – January 28, 2026 – Adelayde Exploration Inc. (the “Company” or “Adelayde”) (ADDY:CSE) (SPMTF:OTCID) (A41AGV:WKN) announces it has entered into a joint venture agreement (“JV”) with Sienna Resources Inc. (“Sienna”) and Cruz Battery Metals Corp. (“Cruz”) to explore the deep basin lithium brine potential in Clayton Valley, Nevada. The 115 mineral claims comprising the 2,300-acre JV land package are all located within, and completely surrounded by, SLB’s (formerly Schlumberger) and Pure Energy Minerals’ Lithium Deposit (see map below). Clayton Valley, Nevada is the only long-established producing lithium brine basin in the U.S., home to Albemarle’s Silver Peak lithium brine mine, which extracts lithium from subsurface brines. It has been the sole U.S. producing lithium brine operation since the 1960’s.

James Nelson, President of Adelayde stated, “Lithium prices are currently at 2-year highs and are now up well over 150% since June 2025, according to tradingeconomics.com⁽¹⁾. With the recent resurgence of investor attention back into the lithium sector, management feels this is an opportune time to explore the deep basin lithium brine potential within Clayton Valley, Nevada. The main reason the JV was formed was to create one large block in the center of the Clayton Valley lithium brine basin to formulate a drill program to test the deepest part with a shared cost and benefit to the JV participants. The Company is well financed to execute its planned exploration and work programs, and we look forward to a very active start to 2026.”
