Nevada Lithium files Technical Report for Bonnie Claire Project. Significantly Increases the Size and Grade of Lower Zone Inferred Lithium Mineral Resources, and Reports Maiden Lithium and Boron Indicated Resources
VANCOUVER, British Columbia, Dec. 16, 2024 (GLOBE NEWSWIRE) -- Nevada Lithium Resources Inc. (CSE: NVLH; OTCQB: NVLHF; FSE: 87K) (“Nevada Lithium” or the “Company”) is pleased to announce that it has filed on SEDAR+ an independent technical report entitled “Mineral Resource Estimate NI 43-101 Technical Report, Bonnie Claire Lithium Project, Nye County, Nevada” dated December 16, 2024, with an effective date of September 24, 2024 (the “Technical Report”). The Technical Report was prepared by Global Resource Engineering Ltd.
The Technical Report was prepared at the request of the Company. The purpose of this Technical Report is to provide updated disclosure on the Company’s Bonnie Claire lithium project located in Nye County, Nevada (the “Project”) in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).
Nevada Lithium’s CEO, Stephen Rentschler, comments:
“We are excited to announce the impact of the new drilling in the Lower Zone of mineralized Lithium and Boron at Bonnie Claire. With the significantly increased tonnage and higher grades, Bonnie Claire is potentially unrivaled by other sediment hosted Lithium projects in Nevada and is amongst the largest and the highest-grade Lithium resources in the world. We have significantly Increased the size and grade of Lower Zone Inferred Mineral Resources at Bonnie Claire to 25.634 Mt LCE at 3,085 ppm Li. We have also reported Maiden Indicated Resources of 5.167 Mt LCE at 3,519 ppm Li and 2.318 Mt B at 8,404 ppm Boron.
Compared to Bonnie Claire’s previous resource report, the new drilling in the Lower Zone has led to a 68% increase in LCE tonnage, at an average grade that has tripled from 1,000 ppm to over 3,000 ppm. It includes intervals where grades exceed 6,000ppm. These increases have occurred using a cut-off grade that has more than doubled to 1,800 ppm. For the first time, we are also able to report a significant high-grade Boron resource that we believe further enhances the Project’s value.
I would like to offer my congratulations and thanks to Nevada Lithium’s Technical Team for this tremendous success. Their dedication and vision have led to results that are of global significance and, in my opinion, will lead to future increases in shareholder value. For further details, please see the Highlights section below as excerpted from the Company’s New Release, dated November 12, 2024.”
Highlights:
- The Bonnie Claire Project comprises an 18,300-acre (74.1 km2; 28.6 mi2) land package with paved highway access, located 2.5 hours by highway from Las Vegas, Nevada. The Project is 100% owned by Nevada Lithium.
- Resources for the deposit have been separated into two Zones; a Lower Zone (i.e., mineralization hosted by Lower Claystone and Lower Sandstone units) and an Upper Zone (i.e., mineralization hosted by an Upper Claystone unit). A very high-grade zone of Lithium and Boron in the Lower Zone remains open in 3 directions.
- The Lower Zone gives an Indicated Resource of 275.85 million tonnes (Mt) at 3,519 ppm lithium (5.167 Mt LCE) and 275.85 Mt at 8,404 ppm Boron (2.318 Mt B), together with an Inferred Resource of 1,561.06 Mt at 3,085ppm Lithium (25.634 Mt LCE). This base-case resource is based on a 1,800ppm Lithium cutoff, constrained by Hydraulic Borehole Mining (HBHM) parameters, and an assumed 60% recovery of the host strata.
- The Upper Zone gives an Indicated Resource of 188.08 Mt at 1,074 ppm Lithium (1.075 Mt LCE) and 152.11 Mt at 1,519 ppm Boron (0.231 Mt B), together with an Inferred Resource of 451.10 Mt at 1,106 ppm Lithium (2.655 Mt LCE) and 270.53 Mt at 1,505 ppm Boron (0.407 Mt B). This resource is calculated at a 900 ppm Lithium cut-off, within a Constraining Pit Shell, and would be mined by conventional open-pit methods
- The updated Mineral Resource Estimate includes assays from eleven (11) additional exploration and infill drill holes completed since the 2021 maiden resource estimate. 2023 & 2024 drilling intersected the lower claystone which hosts the high grade (up to 7,160ppm) Lithium, and which remains open in three directions. It is reasonably expected that the bulk of Inferred Resources can be upgraded to Indicated through additional infill drilling.
- The updated Mineral Resource Estimate will be included into ongoing work on an updated Preliminary Economic Assessment expected for completion at the end of Q1 2025.
Mineral Resource Estimate Details
Lower Zone
While early exploration concentrated on mineralization in the Upper Zone, the Company has shifted its focus to mineralization in the Lower Zone, hosted in the Lower Claystone and Sandstone units and containing the bulk of Lithium and Boron. This Lower Zone remains open to the NW, NE and SE. The current plan is to use an underground Hydraulic Borehole Mining method, with a higher 1,800ppm cut-off. The Mineral Resource Estimate for the Lower Zone is presented in Table 1-1 and the sensitivity of the Lower Zone to cutoff grade is presented in Table 1-2.

Cautionary Statements Regarding Mineral Resource Estimates:
Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. There is no certainty that all or any part of the Mineral Resources will be converted into Mineral Reserves. Inferred Mineral Resources are that part of a Mineral Resource for which quantity and grade or quality are estimated on the basis of limited geological evidence and sampling. Geological evidence is sufficient to imply but not verify geological and grade or quality continuity. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
Quality Assurance / Quality Control (QAQC)
A quality assurance / quality control protocol following industry best practice was incorporated into the drill program by Nevada Lithium. Drilling was conducted by Major Drilling. Core was transported by Major Drilling from the collar location and received by Nevada Lithium staff at the Company storage facility in Beatty, NV. The facility is only accessible to Nevada Lithium staff and remains otherwise locked. Received core was logged and cut at the facility by Nevada Lithium staff. Logging and sampling included the systematic insertion of blanks, duplicates and certified reference material (CRM) MEG Li.10.12 and OREAS 750 into sample batches at an insertion rate of approximately 10%. All core samples collected were transported by Company staff to ALS USA Inc.’s laboratory in Reno, NV. for sample preparation. Sample preparation comprises initial weighing (Code WEI-21), crushing QC Test (CRU-QC), pulverizing QC Test (PUL-QC), fine crushing at 70% <2mm (CRU-31), sample split using Boyd Rotary splitter ((SPL-22Y), pulverizing up to 250g 85% <75 µm (PUL-31), crush entire sample (CRU-21), Pulp Login LOG-24) and a crusher wash (final crusher wash between samples (WSH-21). Samples were shipped to ALS USA Inc.’s Vancouver laboratory in Burnaby BC, where the samples were analyzed using 48-element four-acid ICP-MS (ME-MS61) and B/Li N₂O₂ Fusion – ICP-AES high-grade (ME-ICP82b) procedures.
Data verification by Global Resource Engineering staff included: an on-site inspection of the Project site and core, RC and chip tray storage facilities, check sampling, geologic maps and reports, and manual auditing of the Project drill hole database. GRE’s QPs have been involved with the project since 2018. They visited the site in 2018 after drilling, during drilling in 2020 and 2022. The results from the site inspection, visual sample inspection and check sampling for each drilling campaign are given below. Based on the results of GRE’s QP check of the sampling practices, verification of drill hole collars in the field, results of the check assay analysis, visual examination of selected core intervals, and the results of both manual and mechanical database audit efforts, GRE considers the collar, lithology, and assay data contained in the project database to be reasonably accurate and suitable for use in estimating mineral resources.
The data verification of the drilling campaigns shows that data from the rotary mud drilling was suspect and not used in the resource estimate. Open pit mining and processing methods, costs and infrastructure needs were verified by Ms. Lane in comparison to other similar sized open pit mines operating in the western USA. Borehole mining costs were developed by Kinley Exploration LLC with coordination with GRE. Other cost data used in the report was sourced from the most recent Infomine cost data report. All costs used to determine reasonable prospects for economic extraction were verified and reviewed by GRE and were assessed to be current and appropriate for use.
Metallurgical testing was completed for the Bonnie Claire project by a well-known commercial metallurgical laboratory. GRE reviewed all available metallurgical reports. GRE confirmed that the mineralization found at the Bonnie Claire Project is similar to another project where GRE has performed other consulting work and finds that the test work for Bonnie Claire shows that the material behaves in a similar manner, specifically in Lithium extraction and recovery and reagent consumption. Given the similarities of the Bonnie Claire material to other similar projects, this provides a good basis for benchmarking the metallurgical test. The work appears to be professionally completed and is well documented and is suitable for estimation of Lithium extraction and recovery calculations in this Mineral Resource Estimate.
