Company Also Announces Renewal of IR Program VANCOUVER, BC / ACCESS Newswire / March 6, 2026 / Green Bridge Metals Corporation (CSE:GRBM)(OTCQB:GBMCF)(FWB:J48, WKN:A3EW4S) ("Green Bridge" or the "Company") announces that it plans to ship selected diamond drill core from its Titac Project in Minnesota to a Canadian laboratory to conduct metallurgical testing focused on evaluating potential extraction pathways for titanium dioxide (TiO2) from ilmenite mineralization using the chloride process. The Company is currently conducting a diamond drilling program at the Titac deposit designed to test copper mineralization associated with oxide ultramafic intrusions within the South Contact District of the Duluth Complex. While drill testing for copper, the Company will also utilize recovered drill core to advance its understanding of the metallurgical characteristics of ilmenite-hosted titanium mineralization present at the Titac. The Titac deposit forms part of the Company's broader South Contact District property package, which hosts mineralization containing copper, nickel, titanium, vanadium and other critical minerals within Minnesota's Duluth Complex. Please see the Company's technical report dated September 18, 2024, a copy of which may be obtained under the Company's profile at www.sedarplus.ca for more information. The Company notes that the Titac deposit includes inferred mineral resources. Inferred mineral resources have a great amount of uncertainty as to their existence and as to whether they can be mined economically. It cannot be assumed that all or any part of the inferred mineral resources will ever be upgraded to a higher category. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Importance of the Metallurgical Program Evaluating titanium extraction potential The Titac deposit is hosted in an Oxide Ultramafic Intrusion which contains an average grade of 15% TiO2 and low grade (0.3-0.4%) copper over long intervals making the deposit appealing as a multi-commodity asset1. However, a critical component of the value at Titac is the understanding how the metals can be extracted from the host rock. Metallurgical testing is expected to provide important data regarding the recoverability of TiO2 from ilmenite mineralization at Titac, representing a key step in evaluating the p...
