Arbor Metals Redirects Fall 2026 Exploration Program to Ernst Rare Earth Elements Project in Quebec

NEWS RELEASE ARBOR METALS REDIRECTS FALL 2026 EXPLORATION PROGRAM TO ERNST RARE EARTH ELEMENTS PROJECT IN QUEBEC

Vancouver, Canada – October 19, 2026 – Arbor Metals Corp. (“Arbor” or the “Company”) (TSXV: ABR, FWB: 432) announces that it has revised its Fall 2026 explora�on plans and will redirect its field crew from the previously announced Phase 3 program at its wholly owned Kemlee Lake Lithium Project in Ontario to its wholly owned Ernst Rare Earth Elements (“REE”) Project in northern Quebec.

The decision reflects the growing strategic importance of rare earth elements and the Company’s inten�on to priori�ze near-term explora�on opportuni�es across its cri�cal minerals por�olio. The Company con�nues to recognize the explora�on poten�al of Kemlee Lake, where previous programs iden�fied priority lithium targets, and will evaluate the �ming of further work at that property as part of its ongoing explora�on planning.

The planned Ernst program will focus on systema�c sampling of the property’s principal mineralized showings using a combina�on of man-portable Shaw drilling and surface trenching. This approach is intended to provide addi�onal geological and geochemical informa�on on historically iden�fied REE enrichment and help establish priori�es for future explora�on.

Prospec�ng conducted on the property by Golden Goliath Resources in 2023 iden�fied nine addi�onal radioac�ve anomalies. However, that program did not include a detailed examina�on of the principal showing, where anomalous REE enrichment has historically been documented. The principal showing will therefore be a priority target for the upcoming program. Radioac�vity is not, on its own, a measure of rare earth element grade or economic poten�al.

The Company an�cipates mobilizing its field crew to Ernst within the next few weeks, subject to customary opera�onal considera�ons. The property is accessible via Quebec Highway 389, with the principal showing located north of Manic-Cinq and within walking distance of the highway. This proximity is expected to support efficient field access and program logis�cs.

Management Commentary

“Our decision to focus the Fall 2026 field program on Ernst reflects our assessment of the opportunity to advance a historically iden�fied rare earth target through a focused and efficient explora�on campaign,” said Mark Ferguson, President and Chief Execu�ve Officer of Arbor Metals Corp. “The principal showing has not been examined in detail in the more recent prospec�ng work, and the combina�on of targeted sampling, Shaw drilling and trenching should help us be�er understand its geological characteris�cs. Kemlee Lake remains an important part of our project por�olio.”

Arbor Metals remains commi�ed to conduc�ng its explora�on ac�vi�es in a safe, responsible and environmentally sustainable manner.
