Highlights
- In 2025, Rush Gold Corp. acquired the Legal Tender Property to extend its land position in the Republic Mining District.
- The company outlined multiple high-grade silver-gold targets across a 1.65 km vein corridor.
- Historic mining along 19 shafts highlights priority areas with no previous diamond drilling.
- Satellite data indicate Legal Tender and Skylight may belong to the same hydrothermal system.
- Field programs and WorldView-3 imagery are underway to refine drill targets.
Rush Gold Corp. (CSE:RGN | FSE: B6H) is rapidly expanding its exploration footprint in Nevada’s Republic Mining District. The company is focused on historic silver-gold mines, untested vein systems, and satellite-defined alteration zones. The company is advancing its Legal Tender and Skylight projects through a strategic, step-by-step expansion approach.
Recently, the company expanded its U.S. investor access with an OTCQB listing. Read more.
Building the District Footprint
In September 2025, Rush Gold moved to broaden its presence in Nye County by securing an option to earn full ownership of the Legal Tender Property from Silver Range Resources Ltd. (TSX-V: SNG). The ground lies a few kilometers north of the Skylight Project and covers most of the Republic Mining District, a historic epithermal camp that saw limited production in the early 1900s.
The property hosts past-producing workings at the Farris, Hyland and Black Butte mines, along with numerous shafts, adits, and surface excavations developed along mineralized structures. The option terms required staged cash payments totaling US$200,000 and 1,000 metres of drilling over four years, while a net smelter return royalty and a defined resource payment remain in place.
From Acquisition to Target Definition
After consolidating the ground, exploration shifted to understanding the structural framework of the project. Work identified northeast and northwest-trending vein systems with parallel and en echelon structures extending over a combined strike length of 1.65 kilometers.
These veins had been historically mined through 19 vertical and inclined shafts, yet the property shows no record of diamond drilling. Historic selective grab samples returned assays of up to 1,875 g/t silver and 4.94 g/t gold, indicating the presence of high-grade mineralization, though not representative of the entire property.
Linking Legal Tender with Skylight
As the dataset grew, satellite spectral analysis began to connect Legal Tender with the nearby Skylight Project. Similar ASTER alteration anomalies across both properties suggested they may form part of the same hydrothermal system.
Silica cap rocks mapped at Skylight and high-grade silver veins at Legal Tender are interpreted as representing different levels within a low-sulphidation epithermal environment. Surface mapping indicates that parts of this system may be preserved and largely untested.
Moving Exploration to the Ground
With targets defined, the focus turned to field verification. Geological crews were mobilized to assess rock and soil geochemical anomalies and to follow up on newly identified satellite-derived zones.
At the same time, tasking of the WorldView-3 satellite began over both properties. The aim is to obtain cloud-free imagery and generate high-resolution alteration intensity maps to refine exploration priorities and support drill planning.
The progression from land acquisition to target generation and then to field validation outlines a continuous exploration approach. Legal Tender now forms a key part of Rush Gold’s district-scale strategy, working alongside Skylight to evaluate known mineralized zones and newly identified anomalies across the Republic Mining District.
