Delta Gold Technologies plc

Provisional Patent filed following University of Toronto Research Team Discovery

Delta Gold Technologies PLC (Aquis: DGQ / OTCQB: DGQTF) (the "Company" or "Delta") is pleased to announce that, under the Research Sponsorship Agreement ("RSA") dated 19 June 2025 with the University of Toronto ("UofT"), an invention has been made that has triggered Delta's option to enter into a Technology Licence Agreement ("TLA"). In connection with this important milestone, the Company has filed its first provisional patent application ("Provisional Patent"), securing an early priority date for the intellectual property arising from the research. The provisional patent application relates to:

The provisional patent application covers novel transducer structures for quantum devices.

Following UofT's formal confirmation of the invention, Delta exercised its licence option under the Research Sponsorship Agreement and entered into the TLA, positioning the Company to obtain an exclusive, global licence to the resulting intellectual property.

The Provisional Patent and TLA milestone is a clear example of the Company delivering against its communicated objectives and delivering shareholder and Company value drivers.   This broader Company objective was further evidenced in March 2026 through the signing of a new separate sponsored research agreement entered into with The Pennsylvania State University ("Penn State"), extending Delta's university led innovation and collaboration model beyond the UofT and strengthening access to additional world class research capabilities.

Next Steps:

The details of the filing of the Provisional Patent filing will remain confidential for a period of 18 months. During this period the UofT and the Company will collaborate on the potential filing of specific patent applications. During the 18 month period, additional work within the broad theme filed today will be completed with the objective of further detailing the inventions.

R. Michael Jones CEO of Delta Gold said:

"We are very excited about the discovery made at the UofT and the progress being made at Penn State. The first Provisional Patent filing, which protects the date of our initial invention , represents a very important milestone and the work continues at pace. We recently visited the UofT and Penn State and are very pleased with the progress being made across these research programs and we look forward to establishing direct collaboration across the teams in the near term."

Under the Technology License Agreement the Company will, upon completion of the Research Sponsorship, hold an exclusive, global license on the IP held by the UofT.

At its core, the UofT describes itself as "a catalyst for discovery, innovation and progress, creating knowledge and solutions that make a tangible difference around the globe".

The team at the UofT is led by Principal Investigator Professor Harry Ruda. Professor Ruda, Chair in Nanotechnology at University of Toronto, completed his PhD at MIT and a post-doctoral fellowship at IBM's Thomas J. Watson Research Center in Yorktown Heights. His work has been cited over 8,897 times in his field of expertise.
