Rush Gold Reports on ASTER Image Processing and Highlights Epithermal System Footprint for Skylight Property
thenewswire.com
VANCOUVER, BC, September 18, 2025 – TheNewswire - Rush Gold Corp. (“Rush” or the “Company”) (CSE: RGN | FSE: B6H) is pleased to announce the results of a recently completed *Advanced Spaceborne Thermal Emission and Reflection Radiometer (“ASTER”) satellite image processing.
“The ASTER spectral alteration study results at Skylight, highlight the presence of a widespread precious metal hydrothermal system, says Anthony Zelen, CEO of Rush Gold, he continues, these findings give us better insights into Skylight’s mineralization, guiding exploration toward targets with the strongest potential to create shareholder value.”
Image processing of publicly available ASTER shortwave infrared (“SWIR”) and near-infrared (“VNIR”) bands was completed over the Skylight Property located 60 km northwest of Tonopah in the Royston Hills, Nye County, Nevada. Skylight ASTER image processing has highlighted the presence of combined N-S tending lateritic iron, kaolinite clay, and silica quartz index anomalies that are interpreted to represent alteration footprint of a low-sulphidation epithermal gold-silver system over 1.2 km (Figure 1).
Prior exploration at Skylight which included reconnaissance rock and soil geochemical sampling and limited reverse circulation (RC) drilling indicates that these new alteration anomalies are consistent with anomalous arsenic and silver in soil; gold and silver in rock samples; and RC drilling gold and silver anomalies; in addition to the presence of argillic alteration and dickite clay as identified by hyperspectral analysis of surface rock samples 1.
The ASTER alteration anomalies are observed to flank surface outcrop mapping which indicates the presence of a possible preserved silica cap. The combined exploration dataset to date at Skylight indicates the presence of a significant potentially intact low sulfidation epithermal gold-silver system, which remains largely untested.
