Getty Drills 68.5m of 0.81% Cu from 39.5m and 184m of 0.37% Cu in First Holes at Getty South

Highlights: Getty South delivers near-surface, high-grade copper mineralization, including 68.5m grading 0.81% Cu from 39.5m depth and 184m grading 0.37% Cu Copper mineralization extended 72m below historical intercepts and remains open within broader Induced Polarization (IP) geophysical anomaly First significant drill program at Getty South in ~30 years Step out assays pending for 11 additional holes at Getty South and 3 holes at Getty North Vancouver, British Columbia--(Newsfile Corp. - September 2, 2026) - Getty Copper Inc. (TSXV: GTC) (OTCQX: GTCDF) ("Getty" or the "Company") is pleased to report the initial assay results from its 2026 drilling at the Getty South target, part of the Company's Getty project in the Highland Valley District of British Columbia. Drilling at Getty South has returned broad intervals of copper mineralization, including higher-grade zones near surface, confirming and expanding mineralization identified by historical drilling. These results represent the first significant drilling at Getty South in 30 years and support the Company's ongoing work towards building a modern mineral resource base and discovering additional copper mineralization across the Project. "These first results from Getty South exceeded our expectations. Unlike the drilling at Getty North, the Getty South target is a lot less understood, with limited core available, and historic holes dating as far back as the 1950's missing location, survey or assay data. This program is the first significant modern drilling at Getty South in approximately thirty years. Drillholes GS26-01 and GS26-02 both test a geophysical anomaly that is open beneath the historic mine workings. They demonstrate both bulk intercepts and high-grade zones, with copper grades that are markedly higher than the mined grades within the Highland Valley District. A pattern of stepout assay results is pending to define the orientations of the higher grades, which remain open to the north, south and at depth." - CEO, Ryan O'Regan Results: GS26-01: 184m of 0.37% Cu and 0.4 g/t Ag from 110m depth Including 28m of 0.83% Cu and 0.3 g/t Ag from 113m Which includes 10m of 1.90% Cu and 0.7 g/t Ag from 113m GS26-02: 68.5m of 0.81% Cu and 0.3 g/t Ag from 39.5m depth Including 13.8m of 1.83% Cu and 0.4 g/t Ag from 43.7m Drilling at Getty South was designed to confirm and expand zones of higher-copper grade, test exploration targets based on the Company's new interpretations of historical data and develop a new geological model for the target to support exploration and future resource modeling. Assays are pending for 11 additional holes that were completed at Getty South as part of the spring program.

The mineralization and associated hydrothermal brecciation are developed within a larger breccia body which encompasses most of the Getty South target area, based on historical mapping and relogging of limited historical core. This larger breccia zone has a matrix predominantly of rock flour and contains clasts of older host equigranular intrusive rock and porphyry intrusions, as well as juvenile flow-banded porphyry intrusive clasts interpreted to be synchronous with the breccia-forming event. Both the breccias and mineralization are interpreted to have a porphyry-related origin. The true width of mineralization in the drill holes is yet to be determined. Local supergene oxidation of copper mineralization is present near surface and along faults and will be more fully characterized by ongoing sequential leach assaying. The Company collects a multi-element assay suite with a full QA/QC protocol that may be used to support future mineral resource estimation work.

The Company is preparing for its fully funded 4,000-6,000 metre fall drilling program, which is expected to test exploration targets and additional resource expansion drilling at Getty North and Getty South. Permitting and drill targeting are ongoing at the Company's 100%-owned Dot Property, providing an additional exploration opportunity within the Company's pipeline. Results from the ongoing programs will continue to inform geological modelling, future mineral resource estimation work and exploration targeting across the Getty Project.

Drill holes were sampled at continuous 3m intervals, though samples may be shorter to accommodate geological boundaries. Samples were halved by core saw on site, with one half sent to ALS Laboratories in Kamloops or North Vancouver for preparation and pulps were assayed in North Vancouver. Samples were prepared and assayed following ALS method codes: PREP-31, ME-MS61, and Au-ICP21. Selected samples were also assayed by sequential leach package Cu-PKG06LI, for which a split of the pulp was analyzed at ALS Laboratories in Lima, Peru. The Company followed a QA/QC program involving the use of blanks, standards and duplicates. Incentive Grant Pursuant to the Company's Equity Incentive Compensation Plan, the Company has granted 100,000 stock options (the "Options") to a consultant at an exercise price of $0.98 per share. The Options are exercisable for a period of five years and will vest over a two-year period.
