GRAYCLIFF SHAKESPEARE DRILLING UPDATE

Graycliff Exploration Ltd. has provided an operational update on the continuing exploration drilling campaign at its 100-per-cent-owned Shakespeare gold project located near Sudbury, Ont. The company has completed the first two drill holes of this phase, advancing both its metallurgical testing objectives and its gold zone definition efforts.

"We are making meaningful logistical and geological progress at Shakespeare," stated James Macintosh, chairman.

He added: "Encountering strong alteration zones and dark sulphide-bearing fractured quartz vein material where we anticipated it should be keeps us optimistic that we will see more significant gold assays. The core has been logged, processed and is on its way to Agat Laboratories, and we look forward to sharing the assay results with our shareholders as soon as they become available."

Drilling highlights:

• HQ metallurgical hole D: drilled to a total depth of 225 metres. The hole intersected a visually distinct zone of black smoky quartz from 185 m to 205 m. This large-diameter core provides critical structural data and representative material for coming extraction and concentration testing. This hole was added as a metallurgical sample hole based on the strong results reported in drill hole A (see press release dated June 2, 2026).
• First NQ exploration hole J-62-26: drilled to a total depth of 250 m. This drill hole was designed to test for gold mineralization between metallurgical drill holes A and B, and it encountered a highly prospective mineralized zone between 109 m and 117 m.
• Next hole under way: Drilling on the next exploration hole, hole J-63-26, commenced Monday, Aug. 24.

Core from the two completed holes has been logged and split and is being shipped to Agat Laboratories for preparation and analysis at its facility in Thunder Bay. Assay results will be released immediately upon receipt and verification by the company.

Qualified person and quality assurance/quality control

Bruce Durham, PGeo, a qualified person as defined by National Instrument 43-101, a director of Graycliff, has reviewed and approved the technical content of this release. Core samples are processed under strict QA/QC protocols, including split core sampling, reference standards and analysis at ISO 17025-accredited Agat Laboratories in Thunder Bay, Ont., utilizing screen metallic gold analysis where visible gold is present.
