NEWS RELEASE

ARBOR METALS COMPLETES PROSPECTING PROGRAM AT ERNST RARE EARTH ELEMENTS PROJECT IN NORTHERN QUEBEC

Vancouver, Canada - November 9th, 2026 - Arbor Metals Corp. ("Arbor" or the "Company") (TSXV: ABR, FWB: 432) is pleased to announce the completion of its inaugural prospecting program at its wholly owned Ernst Rare Earth Elements ("REE") Project in northern Quebec.

The field program focused on examining the property's principal showing and identifying additional prospective targets using radiometric surveying. The exploration crew successfully evaluated the principal showing and used radiometric measurements to identify areas of interest for further investigation.

In total, eight grab samples were collected, and ten backpack drill holes were completed for a combined drilling length of 4.32 metres. The program was designed to provide geological and geochemical information to assist Arbor in evaluating the property and prioritizing potential follow-up exploration.

Samples collected during the program will be submitted to ALS Laboratories for analysis using the ME-MS71L method, a super-trace ammonium bifluoride (NH4HF2) digestion method with inductively coupled plasma mass spectrometry (ICP-MS) determination. The Company will assess the analytical results when available to help determine the next steps for the Ernst Project.

As previously disclosed, prospecting conducted by Golden Goliath Resources in 2023 identified nine additional radioactive anomalies on the property. The Company's current program included examination of the principal showing, which was not examined in detail during that earlier work. Radiometric responses can help identify exploration targets but do not, by themselves, establish rare earth element grades or economic potential.

Francis R. Newton, PGeo (OGQ No. 2129), a consultant to Arbor and a qualified person under National Instrument 43-101 - Standards of Disclosure for Mineral Projects, has reviewed and approved the scientific and technical information in this release.
