Nevada Lithium Resources Inc. (CSE: NVLH) (OTCQB: NVLHF) (FSE: 87K) is pleased to provide the core assay results for the second and final diamond drill hole from the 2024 drill program at its 100% owned Bonnie Claire lithium project, located in Nye County, Nevada. BC2402C is an infill hole, collared 817 feet (249 m) to the southeast of BC2301C. The hole reached a total depth of 3,002 feet (915 m) and intersected thicker, deeper high-grade mineralized rock towards the southeast for the first time.
Nevada Lithium’s CEO, Stephen Rentschler, comments:
“The results from our final hole of the 2024 drilling program are tremendous. Hole BC2024C generated two exciting and important conclusions. The first is the remarkable continuity that exists in the deep high-grade Lithium and Boron mineralized zone that we first encountered in our 2023 drilling program. We anticipate that this demonstrated continuity will significantly increase the geostatistical confidence in this zone.
This demonstrated continuity is extremely important for the support of the mine planning that is currently underway to update our existing PEA. This update will, for the first time, include the impact from the deep high-grade Lithium and Boron zone that now extends over 1km from the southwest to the northeast.”
He continued, “Although designed as an infill hole, BC2402C also confirmed the extension of the high-grade Lithium and Boron zone to the southeast. With the results of this hole, we have confirmed that the high-grade mineralization remains open in at least two directions. Our technical committee also remains confident that this high grade mineralization extends in yet another direction, to the northwest.
Bonnie Claire’s massive, existing Lithium resource currently does not include the tremendous results from our past two drilling programs. However, the data suggest that we have yet to find the deposit’s sweet spot. Therefore, the potential to add high-grade Lithium and Boron tonnages to Bonnie Claire in the future is nowhere near exhausted. We are moving as quickly as possible to demonstrate the enhanced world-class attributes of Bonnie Claire and anticipate the first of a series of updates to be completed in the very near future.”
Highlights:
The 2024 drill program completed two holes with complementary goals. Drill Hole BC20241C was completed to examine the northeast extension of the deep high-grade mineralization that was intersected in the 2023 campaign. In contrast, BC2402C was completed to investigate grade continuity within the existing mineral resource to support mine planning.
BC2402C is collared 817 feet (249 meters) to the southeast of BC2301C. It was planned as an infill hole to:

Results and Interpretation
Mineralization Continuity
BC2402C tightens the drill spacing in the southeast part of the mineral resource area. The drill results from BC2402C have increased confidence in the grade continuity of the high-grade deep Lithium and Boron mineralization with the nearest hole BC2301C, which returned 3,076 ppm Lithium over 1,100ft (335 m) (See the Company’s news release dated November 20, 2023).
A visual examination of the downhole grade graphs provides a remarkable visual correlation between BC2301C and the new hole BC2402C, particularly in Boron (Figure 1). These assays will be included in an ongoing mineral resource estimation being conducted by Global Resource Engineering. It is anticipated that infill holes like BC2402C will increase the geostatistical confidence in grade with surrounding drillholes. This increased geostatistical confidence is necessary to move mineral resources in the vicinity from Inferred to Indicated category.
While BC2402C displays great similarity with BC2301C in downhole grade distribution, the grades and thicknesses intersected are significantly larger. The 600 ft (183 m) of 4,089 ppm Lithium encountered in BC2402C was significantly thicker than the 360 ft (110 m) of 4,291 ppm Lithium encountered in BC2301C. The same interval in BC2402C has a weighted average Boron assay of 1.47%, indicating the high-grade Boron mineralization also continues to the southeast.
The general increase in grades seems to correlate with an increase in depth, as the highest Lithium grades occurred roughly 100 ft (30 m) deeper in BC2402C than in BC2301C. The highest assay in BC2402C is 6,150 ppm Lithium from 2,307 ft (703 m) to 2,327ft (709 m).
The upper mineralized zone maintained a similar thickness to elsewhere, but was slightly lower grade in BC2402C, averaging 909 ppm Lithium over 260 ft (79 m).
High-Grade Extension to Southeast
Previous deep drilling at Bonnie Claire has been focused on following the increasing grades to the northeast, and BC2402C is the first hole to see this trend occurring to the southeast as well (Figure 2). Hole BC2402C extends high-grade deep mineralization 817ft (249m) to the southeast. Grades and thicknesses increase to the southeast and remain open in that direction. The trend of deeper mineralization providing higher grades continues and has now been demonstrated to the northeast and southeast of the existing resource area (Figure 2).

Quality Assurance / Quality Control (QAQC)
A quality assurance / quality control protocol following industry best practice was incorporated into the 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.
Standards, duplicates and blanks in the drill results to date have been approved as acceptable. The standards performed well (100% within 95% confidence limits for lithium and boron) as did duplicates (R2 = 1) and all blanks (average 16ppm Li, <0.02%B).
