The Legal Tender and Skylight properties are 3 kilometers apart.

The winter 2025 Royston Hills geologic reconnaissance resulted in the collection of 124 surface rock grab samples. The samples have been submitted for gold fire assay, multi-element geochemical, and TerraSpec® analysis to ALS Global (“ALS”), Vancouver, Canada. Assay results are expected early in the new year.

The Company confirms that it has received notice from its satellite provider Vantor Inc. and PhotoSat that a successful cloud-free image acquisition occurred on December 3, 2025. Full results of the alteration mineral mapping study area are expected in the coming days.

Anthony Zelen, CEO of Rush Gold, stated the company is pleased to have successfully completed its first ground sampling campaign in Nevada at its Legal Tender and Skylight properties and looks forward to reviewing assay results in the new year, in addition to the results of the satellite alteration mineral mapping study.
