THUNDER BAY, ON , June 29, 2026 /CNW/ - Errington Metals Corp.(TSXV: EM) ("Errington" or the "Company") is pleased to announce that it has been awarded a total of $700,000 in direct support from the Government of Ontario through two separate initiatives: the Critical Minerals Innovation Fund ("CMIF") and the Ontario Junior Exploration Program ("OJEP"). The funding will support technical studies and exploration at the Company's Sudbury Basin Project, which is being advanced as a potential near-term source of copper and zinc--both recognized as critical minerals by the Government of Canada--and associated precious and base metals.

"This funding is a strong endorsement of the critical-minerals potential of the Sudbury Basin Project and the importance of advancing domestic sources of copper and zinc," said Matthew Gollat, President and CEO of Errington Metals. "Support from CMIF and OJEP allows Errington to accelerate metallurgical work, evaluate new exploration targets and advance a project that is well aligned with Ontario's critical minerals strategy."

The CMIF initiative supports research, development and commercialization of innovative technologies, techniques, processes and solutions that strengthen Ontario's critical minerals supply chain. Errington Metals will receive a total of $500,000 to advance a systematic metallurgical study using conventional methods and recently developed techniques designed to improve recovery of copper, zinc, gold, silver and lead from polymetallic sulphide mineralization. The funding is expected to contribute approximately 50% of the metallurgical program over the next year and will help evaluate processing pathways that could enhance future critical-minerals recovery from the Project.

The $200,000 received from OJEP was used to explore new areas with high potential to host mineralization similar to the known mineralized centres on the property. Interpretations of bedrock geology and airborne geophysical surveys identified several areas where the prospective host-rock sequence may occur below cover but has not yet been tested. This work supports Errington's objective of building a pipeline of copper- and zinc-rich critical-minerals targets across the Sudbury Basin Project.

In addition, OJEP funds were used to complete a magnetotelluric geophysical survey across the Errington mineralized zone. This method measures resistivity to depths of approximately 500 metres to 1,000 metres below surface and may assist in detecting sulphide mineralization characterized by low-resistivity responses. The geophysical data continue to be evaluated; however, preliminary results indicate that the method has successfully identified known areas of mineralization and detected additional low-resistivity areas that have not yet been drilled.

About Errington Metals

Errington Metals Corp. is a focused Canadian exploration and development company targeting critical and precious metals. The Company is advancing its wholly-owned Sudbury Basin Project, which hosts high-grade volcanogenic massive sulphide ("VMS")-style mineralization in the world-renowned Sudbury mining district. The Project contains copper and zinc, two metals identified as critical minerals in Canada, together with associated gold, silver and lead. Errington Metals aims to efficiently assess this opportunity and advance high-quality targets through systematic drilling, metallurgical studies and other technical work.

In 2026, the Company is completing a 45,000–metre drill program designed to support an initial mineral resource estimate and test regional targets.
