B&N Mining Commences Spring 2026 TEM Geophysical Survey at the Lida Valley Lithium Project, Nevada

Lida Valley, Nevada — March 2026 — B&N Mining Company LLC (“the Company” “B&N Mining”) announces that it has commenced its Spring 2026 Transient Electromagnetic (TEM) geophysical survey across the Lida Valley Lithium (LVL) Project in southwestern Nevada.

The program represents the next phase of basin-scale exploration designed to refine drill targeting across the consolidated LVL, EZ, and Gemini claim blocks, which together form a district-scale lithium claystone exploration project within the Walker Lane structural corridor. The survey is being conducted by Zonge International, a geophysical contractor specializing in electromagnetic surveys for mineral exploration and basin studies.

The current program consists of five new TEM survey lines strategically positioned to connect with previously completed geophysical lines across the Gemini Basin and extend coverage eastward toward existing LVL drill holes. By tying the new survey lines directly into the earlier Gemini dataset, the Company aims to create a continuous geophysical framework across the broader Lida Valley basin system.

The LVL Project currently encompasses more than 17,000 acres across 849 unpatented mining claims administered by the Bureau of Land Management, providing control of the principal basin floor and multiple structural lows interpreted to host lithium-bearing claystone deposits.

Purpose of the TEM Survey

Transient Electromagnetic (TEM) geophysics is particularly effective in lithium claystone systems because lithium-bearing clay units typically exhibit elevated electrical conductivity relative to surrounding basin sediments.

The current survey program is designed to:

• Extend geophysical coverage from the Gemini Basin into the LVL/EZ basin
• Map conductive claystone horizons associated with lithium mineralization
• Identify structural lows that may host thicker lithium-bearing clay sequences
• Refine drill targeting for the Company’s planned 2026 drilling campaign

Previous TEM surveys conducted in the Gemini Basin identified conductivity anomalies that were subsequently tested by drilling and successfully intersected thick lithium-bearing claystone intervals. The results provided confidence in the effectiveness of the geophysical method and helped establish the current basin-scale exploration model.

The new TEM lines will build on this success by expanding the geophysical grid eastward across the LVL Project and integrating the Gemini dataset with the Company’s growing drilling database.

Integration with the 2026 Exploration Program

Interpretation of the TEM results will directly guide the location of planned drill holes for the Company’s upcoming exploration campaign. The program currently anticipates approximately 10 drill holes totaling 12,000–17,000 feet, designed to test basin geometry, extend known mineralization, and advance priority targets toward resource definition.

Statement from the Chief Geologist

“Launching this TEM program represents an important step in refining our understanding of the Lida Valley basin system,” said Liam Eades, Chief Geologist for the Lida Valley Lithium Project

“Earlier geophysical work in the Gemini Basin successfully identified conductive claystone targets that were later confirmed by drilling. By tying this new survey directly into those earlier lines and extending coverage toward our LVL drill holes, we are building a continuous geophysical picture of the basin and improving our ability to target the thickest parts of the lithium-bearing clay system.”
