PolarX Announces Outstanding Geophysics Results and Sampling Assays from Their Alaska Range Project

Together the Results Highlight Potential for a Major Copper-Gold System

ANCHORAGE, Alaska, May 28, 2026 /PRNewswire/ -- PolarX Limited (ASX: PXX; OTCQB: PXXXF) announced outstanding geophysics results and surface sampling assays that together highlight the potential for a major copper-gold system at the company's Alaska Range Project.

New 3D magnetic inversion modeling has identified a large magnetic body with a diameter of 3.5km that extends north from the Zackly magnetite skarn deposit across Jupiter to the Gemini prospect. High-grade surface mineralization directly overlies several magnetic apophyses interpreted to emanate from the deeper intrusive body, significantly enhancing the prospectivity of the system for large-scale intrusion-related copper-gold mineralization.

A total of 128 rock chips were collected and samples, returning widespread high-grade copper and gold results at the Jupiter and Mars and surrounding prospects.
