CMC Announces that North Bay Resources has significantly advanced its planned operations at Bishop Gold Mill, Inyo County, California

September 26, 2024. Vancouver, B.C. CMC Metals Ltd. (TSX-V: CMB) (Frankfurt:ZM5P) ("CMC" or the "Company") is very pleased to acknowledge that North Bay Resources Inc. (OTC:NBRI) have announced yesterday that they have made significant progress as follows:

dot the arrival of its first gold ore shipment at the Bishop mill facility from its Fran Gold Project and commencement of test milling operations has been initiated. NBRI will immediately begin testing and optimization of milling for extraction of gold from ore.

dot The initial shipment consisted of 22 tons of surface material loaded into one metric tonne (2200 lbs.) super-sacks and placed on flat-bed tractor trailers.

dot Target material from its Fran Gold Project was recently assayed and graded 1.2 to 2.3 ounces gold per ton (see NBRI Press Release dated August 26, 2024). The actual grades and recoveries will be determined after test processing is completed and reported assays should not be currently relied upon in any manner as they have not been verified by the Company.

dot NBRI has received a tailings pond inspection report from its environmental engineering firm, NewFields, indicating no issues or degradation of the tailings pond liner in the Waste Management Unit of the Bishop Gold Mill and its civil and process engineering firm SRK Consulting (Reno) is completing a De-watering Plan and updated Waste Management and Closure Plan as part of its ongoing information requirements with California State regulatory authorities.

dot NBRI also notes that its has filed the required Federal Mining Authority (MSHA) operating plan and expects to commence operations at the Mt. Vernon Gold Mine in October. The initial detailed extraction plan for the drill, blast, load, and removal of a 500-ton high grade bulk sample is being updated and completed, based on prior 3D modelling, by the Company's mine engineering consultant, RESPEC Company, and is expected shortly; site preparations are expected to commence thereafter. -2-

This is a significant milestone in that project.
