Program Confirms Near-Surface Economics, Advances Crucial Data Collection and Further Defines High Grade Core
West Vancouver, British Columbia -
Newsfile Corp. - February 25, 2026 - Surge Battery Metals Inc. (TSXV: NILI) (OTCQX: NILIF) (FSE: DJ5) (the "
Company" or "
Surge") is pleased to announce that Nevada North Lithium LLC ("NNL"), the joint venture formed by Surge and Evolution Mining Limited ("Evolution"), has reported the second and final batch of assay results from its 2025 core drilling program at the Nevada North Lithium Project ("NNLP"). Following the successful step-out results reported in Part 1 (
see news release dated February 17, 2026), these final five holes focused on infill drilling to support the upcoming Pre-Feasibility Study ("PFS"). The results confirm the continuity and high grade of the deposit's core.
Highlights from the Final 5 Holes:- Significant High-Grade Intercepts: Hole NNL-030 intersected a cumulative thickness of 116 meters (381 ft) averaging 3,752 ppm Lithium (Li), including a high-grade upper zone of 32.1 meters (105 ft) grading 4,521 ppm Li.
- Deposit Continuity: Hole NNL-036 confirmed the robustness of the resource, returning 78.6 meters (258 ft) averaging 3,141 ppm Li, including a deep, high-grade basal zone grading 4,580 ppm Li.
- Critical Hydrogeological Data: Hole NNL-035, strategically positioned near Texas Spring, provided essential groundwater monitoring data. While this hole intersected a high-energy fluvial channel (resulting in naturally eroded clay horizons), it successfully installed Vibrating Wire Piezometers (VWPs) to model the basin's hydrology-a key requirement for the PFS and permitting.
- Critical Geotechnical Data: Successfully captured high-resolution televiewer data and completed geotechnical logging across all 2025 drill holes, ensuring precise modeling of fault structures. Representative samples from every lithological unit are now undergoing rock strength testing to define safe pit wall angles for the PFS.
- Strategic By-Product Potential: Infill drilling consistently returns consistently elevated concentrations of Cesium (up to 163 ppm) and Rubidium (up to 349 ppm) directly associated with the lithium core. The Company is actively evaluating the deportment of these high-value critical minerals in the ongoing metallurgical study, representing an opportunity for the project's value proposition.

True Thickness and Interval Calculation Sample intervals were determined based on easily identified lithological contacts, such as the distinct tuff/clay boundary. While nominal sample lengths were typically 5 feet (1.52 meters), some intervals were adjusted to respect these geological contacts. All reported composite grades account for these variations and are length weighted. All drill holes in this program are vertical. Because the local geology generally dips at approximately 20 degrees to the west, the true thickness of the mineralized intervals is estimated to be approximately 94% of the reported drilled thicknesses.
Drill Results DiscussionHigh-Grade Infill (NNL-030, NNL-031, NNL-032, NNL-036) The primary objective of these holes was to convert Inferred Resources to the Indicated and Measured categories. The results exceeded expectations, with consistent mineralization intersected across significant widths. Hole NNL-030 stands out as a top-tier intercept, returning nearly 120 meters averaging >3,700 ppm Li, confirming the presence of a thick, ultra-high-grade core that will likely drive early-year economics in the mine plan. Hole NNL-032, in the center of the current resource, bolsters the high Li grades and thicknesses of horizons in the center of the deposit. Hole NNL-033 fills in a critical area in the north of the resource, connecting the two-hole pad in the northeast to the rest of the mineralized sequence. Hole NNL-035 targeted a strategic hydrogeological location near Texas Spring. Drilling encountered a localized fluvial scour zone, resulting in a thinner mineralized interval (23.1m @ 1,743 ppm Li). Crucially, the hole was successfully completed as a monitoring well with Vibrating Wire Piezometers (VWPs) . This installation provides the essential groundwater data required to calibrate the regional model and de-risk the environmental permitting timeline. Hole...
