Lithium Butte Claystone Property Encourage Results

VANCOUVER - Rockland Resources Ltd. reported encouraging assay results on channel samples from lithium-mineralized claystones on the Lithium Butte Property in Juab County, Utah. Channel samples returned a continuous interval of 25.2 meters at 1,388 parts per million ("ppm") lithium ("Li") including 8.0 meters at 2,155 ppm Li, and 0.7 meters at 3,540 ppm Li. The 4,460 ha (11,020 acre) Lithium Butte Property is located in the Basin and Range geological province of west-central Utah and is interpreted to be highly prospective for lithium (Li) and beryllium (Be) mineralization hosted in claystone volcanic tuff-breccia units.

Twenty-one (21) channel samples were taken from an exposed outcropping of claystone on the Property in July 2022. Fifteen (15) channel samples with lengths from 1.0 to 2.0 m were taken from a single stratigraphic section of claystone exposed beneath the rhyolite cap rock that forms the top of the exposed butte. The total length of the main channel section (15 samples) is 27.0 m. True stratigraphic thickness is estimated at approximately 70% of the channel length. This main channel section returned 25.2 m at 1,388 ppm Li. The lower portion of the mineralized section returned a higher-grade interval of 8.0 m at 2,155 ppm Li. The sampled section represents the upper part of the prospective unit and the mineralization is open at depth.

Additionally, two shorter channel sections, each with 3 channel samples, were taken over the exposed outcrop of the prospective unit, from 15 m northwest and 28 m southeast along strike from the main channel. These shorter sections returned 1,732 ppm Li over 1.25 meters and 1,925 ppm Li over 1.7 meters, respectively. The shorter channels indicate Li claystone mineralization over a strike length of at least 43 m with mineralization being open along strike and below the channels. The southeast channel section contained the highest-grade lithium mineralization in this sampling program with 0.7 m grading 3,540 ppm Li.

Richard Sutcliffe, President, said, "These channel sample results are an excellent validation of the initial grab sample results from this Project that Rockland reported in June. Importantly, the samples confirm a significant stratigraphic thickness of lithium-rich mineralization on the Property. To advance our exploration program, we have recently established an office in Delta, Utah and are in the process of setting up a facility to provide rapid analysis of rock and soil samples using a Laser Induced Breakdown Spectrometer (LIBS). This technology will allow Rockland to quickly evaluate additional exploration and drill targets. We look forward to developing this program to evaluate regional lithium mineralized claystone targets in the Basin and Range Province of Utah. The Company is currently staking additional claims and we will provide additional Property details once staking has been completed."
