August 22, 2025 / Vancouver, BC / Lithium South Development Corporation (the “Company” or “Lithium South”) (TSX-V: LIS) (OTCQB: LISMF) (Frankfurt: OGPQ) has engaged Patrick Sullivan at Whitelaw Twining to file a petition in Ontario Supreme Court against CEO.CA to identify a trio of users that are making false and misleading posts on their forums.
The purpose of the petition is to provide identifying information for the users “R1505”, “78Brooks” and “Amiga500”. The information is to include names, addresses, phone numbers, e-mails, payment information or anything else that might provide the identities of the users. The reasoning behind this request is that these users wrote material that is clearly defamatory against the Company as well as certain officers and directors. Once the Company is in possession of their identities, the Company will be in position to pursue a lawsuit over the material of these posts.
Company President and Chief Executive Officer Adrian Hobkirk is quoted as saying “While websites like CEO.CA provide a forum for investors to discuss public company matters, there is a difference between providing thoughts and opinions and making accusatory and defaming comments. Instead of asking the Company questions, certain individuals are disseminating false and misleading material misinformation, and they need to be held accountable.”
