Greenfield Update

TomCo Energy plc (AIM: TOM), the US operating oil development group focused on using innovative technology to unlock unconventional hydrocarbon resources, provides the following update in respect of the work being undertaken by Greenfield Energy LLC ("Greenfield"), the Company's 50/50 joint venture with Valkor LLC ("Valkor"), with respect to Petroteq Energy Inc's ("Petroteq") existing oil sands plant at Asphalt Ridge, Utah (the "POSP").

As announced on 18 May 2021, Utah's Division of Oil, Gas and Mining ("DOGM") issued a Cessation Order (the "CO") on 14 May 2021 in respect of the POSP's operations at the Temple Mountain Mine being operated by Greenfield. Greenfield is pleased to report that following a conference with the DOGM on 21 May 2021, Petroteq received notice from the DOGM on 25 May 2021 that it was modifying the CO so that operations could immediately recommence at the site. The modified CO will allow processing and testing operations at the POSP to take place until 30 June 2021. Operation of the POSP after that date will be subject to Petroteq submitting a complete Notice of Intent before 1 July 2021, satisfactory to DOGM, covering, inter alia, mineral processing methods and facilities, waste handling and management and reclamation plan. Greenfield intends to work with Petroteq with a view to ensuring that this requirement is met.

Further updates will be made as and when appropriate.
