ERRINGTON METALS APPOINTS HAROLD GIBSON AS TECHNICAL ADVISOR AND BEGINS FALL DRILL CAMPAIGN

Errington Metals Corp. has appointed Dr. Harold L. Gibson, PGeo, as a technical adviser to the company and has commenced its fall drill campaign, focused primarily on the Vermilion property.

"One of the most rewarding aspects of growing this company and advancing the project has been the calibre of people we continue to attract. We are very pleased to welcome Harold as a technical adviser to Errington. Harold brings highly relevant technical knowledge to our team. He has over four decades of global VMS expertise, plus has direct exploration and research experience within the Sudbury basin," commented Matthew Gollat, president and chief executive officer of Errington Metals. "In addition, with our strong balance sheet, we are entering the next phase of the company's development and growth with the initiation of our fall drill campaign. We are committed to executing our plan in a methodical and thoughtful manner, supported by the quality of our people and a disciplined focus on maximizing value per share."

Dr. Harold L. Gibson

Dr. Harold L. Gibson, PGeo brings more than 40 years of expertise in VMS (volcanogenic massive sulphide) systems, developed through the study of VMS deposits, and their diverse volcanic environments around the world and on the modern seafloor. He is currently vice-president, exploration, for VMS Mining Corp. and exploration consultant, as well as an emeritus professor of volcanology and ore deposits at the Harquail School of Earth Sciences at Laurentian University in Sudbury, Canada. Dr. Gibson formerly served as director of Laurentian University's Mineral Exploration Research Centre and was the scientific lead and founding director of the $104-million metal-earth research project, Canada's largest multiuniversity, industry and government-financed mineral exploration research initiative.

Dr. Gibson has authored or co-authored more than 100 peer-reviewed publications and has received numerous awards recognizing his contributions to economic geology and mineral exploration, including the William Harvey Gross Award and Duncan R. Derry Medal from the mineral deposits division of the Geological Association of Canada; the Barlow Memorial Medal and Julian Boldy Memorial Award from the Canadian Institute of Mining, Metallurgy and Petroleum; and Laurentian University's Research Excellence Award.

Before entering academia, Dr. Gibson had a successful 12-year career in mineral exploration. Throughout his career he has consulted for numerous global mining companies and been part of several VMS discovery teams. Of particular relevance to Errington is his work with Falconbridge Ltd., directing exploration within the Sudbury basin focused on discovery of new mineralized systems analogous to Errington and Vermilion.

Fall 2026 exploration program

The company has mobilized an initial drill rig to Vermilion to test the potential extensions of the mineralized zone along strike and down dip as well as validate historic drilling to improve future resource estimations. A second drill rig will also commence shortly thereafter to accelerate the program. Additional targets near Vermilion will also be tested based on geological and geophysical data interpretations. The drilling program at Vermilion is expected to extend through the fall. A third rig is expected to arrive in October that will focus on collecting representative mineralized material from Errington for a planned mini-pilot metallurgical test schedulled for 2027.
