Abbotsford, British Columbia--(Newsfile Corp. - August 20, 2026) - Super Lithium Corp. (CSE: SL) ("Super Lithium" or the "Company") is pleased to announce it has received results from its initial exploration program on its Railroad Valley Lithium Project in Nevada. The exploration program was designed to build on preliminary work completed in 2022 suggesting brine potential at depth. This program utilized Magnetotellurics (MT) to better define the feature at depth. A supporting soil geochemistry survey was undertaken and shows a geographic correlation between the resistivity zone at depth and high lithium in soil geochemistry.

Geophysics

Previously, a 2-line ~7km CS-AMT survey was completed over the project area that highlighted some brine potential at depth. However, that survey only reached a depth of 600 metres. To follow up on this work, a second survey was conducted using magnetotelluric (MT) methodology, which was able to penetrate to a depth of 1,800 metres and highlighted the zones suggested in the first survey. These zones coincide with elevated geochemical results (discussed below). The images below show the comparison in the 2-D definition in the more recent survey, as well as inversions between the earlier CS-AMT and the recent MT survey showing the increased definition in the resistivity anomaly at depth to the east.

Geochemistry

A total of 166 soils samples were collected at a spacing of 250 metres across the entirety of the property. The historic NURE data observed the highest regional values between 105-247ppm (22 samples). Of the 166 samples collected on this program, 86 returned assays above 105ppm with the highest value of 181ppm (24 of these samples fit into the highest value category from the NURE dataset in the region). The highest values are in the northeastern corner of the property coincident with the previously highlighted geophysical anomaly zone. There is a secondary weaker zone to the northwest, and one in the center of the property.

About the Railroad Valley Property

The Railroad Valley Property consists of 112 unpatented claims comprising a total of approximately 906 hectares (2,240 acres) in Nye County, Nevada. The project is accessible via Nevada State Highways. There is a lack of historic work on this parcel prior to 2017 making it an attractive, underexplored property. Railroad Valley is a classic Basin and Range graben basin bounded on all sides by dip-slip faults. The basin appears to be asymmetric, with a "trap door" configuration with the southeast side of the valley being deeper than the northwest side. There are regional lithium geochemical data from the National Uranium Resource Evaluation (NURE) database throughout the Railroad Valley ranging from 13-247ppm. The geologic setting, combined with the presence of lithium in both active geothermal fluids and surface salts within the Railroad Valley property position match characteristics of lithium brine prospects in other Nevada basins.

The main mineral target at the Railroad Valley project is a playa-related lithium brine deposit similar to productive playas in Clayton Valley, Nevada, and several areas of South America. In 2013, Bradley defined seven characteristics of lithium brine deposits: Arid Climate; Closed Basin containing a playa or salar; Tectonically driven subsidence; Associated igneous or geothermal activity; Suitable lithium source rocks; One or more adequate aquifers; Sufficient time to concentrate brine. The Railroad Valley Project is known to have all seven of these characteristics. While this correlation is no guarantee of a deposit, this provides the Super Lithium Team with strong support for exploration work.
