Vancouver, British Columbia--(Newsfile Corp. - July 24, 2026) - Adelayde Exploration Inc. (CSE: ADDY) (OTCID: SPMTF) (WKN: A41AGV) (the "Company" or "Adelayde") is pleased to announce that it has executed a drilling services agreement with Titan Drilling Ltd. ("Titan") to conduct the Company's fully funded inaugural drill program at its 100%-owned Clayton Ridge Gold Project, located in Esmeralda County, Nevada.

Highlights:

• Drilling expected to commence in the coming days on Clayton Ridge Gold Project, Nevada.

• Adelayde is fully funded to aggressively advance multiple work programs across its portfolio through the second half of 2026, including gold in Nevada and antimony in New Brunswick.

• Data results from the Company's Lake George Antimony Project are expected shortly.

• Well positioned with two critical defense metals projects amid tightening supply, escalating geopolitical hostilities and rising global demand for secure North American sources.

James Nelson, President of Adelayde, stated, "This drill program represents the Company's first drilling campaign on a project that we believe has been under-explored relative to its potential and is an important milestone for the Company. With a strong treasury, we are well positioned and funded to advance multiple exploration programs across our portfolio including the Lake George Antimony project where we expect data results back shortly. Our project portfolio includes both antimony and tungsten, providing us with exposure to two critical defense metals. With global supply chains facing continued disruption and geopolitical tensions increasing, secure North American sources of these strategic commodities are becoming increasingly important. We expect to be very active on multiple projects and look forward to providing updates as our exploration activities progress throughout the remainder of the year."
