Zimtu Capital : Aduro Clean Technologies Announces Investor Relations Agreement with Digitonic Limited

Sarnia, ON, August 17, 2021 - Aduro Clean Technologies Inc. (CSE: ACT) (OTCQB: ACTHF) (FSE: 9D50) (the 'Company' or 'Aduro Clean Technologies') is a developer of patented water-based technologies to chemically recycle plastics and transform heavy crude and renewable oils into new-era resources and higher-value fuels. The Company is pleased to announce that it has entered into an agreement with Digitonic Limited ('Digitonic') to provide marketing and investor relations services.

Digitonic, a mobile marketing and investor relations firm based in Glasgow, Scotland, will provide content creation, distribution, and advertising services focused on the North American market. Under the terms of the agreement, dated July 27, 2021, Digitonic has agreed to provide services to the Company in exchange for an aggregate amount of US$216,000 in cash for a period of six weeks. The term of service will commence after Aduro Clean Technologies announces the successful demonstration of the Company's Hydrochemolytic™ technology (HCT) for upgrading heavy petroleum feedstock to lighter petroleum oil using its continuous-flow pre-pilot reactor to be witnessed and validated by a third party.

'The completion and independent validation of HCT in the pre-pilot system is an important step in our journey, as it is the formal affirmation that our novel chemical conversion technology is effective and it sets the stage for our pilot unit and eventual commercialization,' said Ofer Vicus, CEO of Aduro Clean Technologies. 'With DTC eligibility anticipated in the near future for electronic clearing and settlement in the US, the digital marketing capabilities of Digitonic will ensure the broad investment community and potential commercial partners are fully informed of our progress.'
