Significant Beryllium Assays On The Lithium Butte Claystone Property


VANCOUVER - Rockland Resources Ltd. reported additional grab sample assay results from the Lithium Butte Property in Juab County, Utah, that show significant beryllium concentrations with values up to 4,810 ppm beryllium. The Lithium Butte Property is located in the Basin and Range geological province of west-central Utah and is interpreted to be significantly prospective for lithium (Li) and beryllium (Be) mineralization hosted in claystone volcanic tuff-breccia units. The Company has staked an additional 27 claims (540 acres) at the Lithium Butte property bringing the total number of claims to 551 claims or 11,020 acres (4,460 ha).

Ten grab samples from the property were taken on a reconnaissance sampling program in May, 2022. Three of the grab samples returned significant beryllium concentrations with assays of 4,810 ppm Be, 4,290 ppm Be, and 1,790 ppm Be. These samples also contain anomalous Li with 380 ppm Li, 440 ppm Li, and 402 ppm Li respectively. The Be-mineralized samples were collected from an outcrop of bedded tuff-breccia approximately 340 meters east-southeast of the claystone tuff-breccia samples that contained previously reported high lithium values ranging from 4,080 ppm to 1,200 ppm Li.

Richard Sutcliffe, President, said, "Our early work at Lithium Butte is demonstrating that the Property hosts a volcanic formation that has a unique endowment in light metals including lithium and beryllium. This formation exhibits strong similarities with the Miocene Spor Mountain Formation that hosts currently mined Be deposits. Our initial results at Lithium Butte suggests that the Spor Mountain Formation may be more widespread than previously thought and has encouraged Rockland to significantly extend its property position in this region."

Company personnel have recently conducted additional sampling from the clay altered rhyolite tuff breccia that returned the lithium assays up to 4,080 ppm lithium . The exposure has a stratigraphic thickness estimated to be greater than 20 meters and contains at least two intervals of claystone mineralization, each of which is several meters in thickness. Channel sampling was conducted across the stratigraphic section and along strike on an exposed dozer road cut. A total of 24 additional samples including 20 channel samples have been submitted to ActLabs laboratory for multi-element analysis using using sodium peroxide fusion and inductively coupled plasma mass spectrometry (ICP-MS).

The geochemical soil sampling program previously announced has been completed, involving approximately 1,000 soil samples taken at 150 meter intervals on east-west lines spaced at 300 meters for a total of 145.5 line-km of sampling, over the entire Lithium Butte property. North American Exploration of Layton, Utah was retained to complete the geochemical soil sampling program. A handheld Laser Induced Breakdown Spectrometer (LIBS) capable of light metal detection (including lithium and beryllium) has been purchased from SciAps Inc., of Woburn, MA, and is currently being shipped to the property. The soil and rock samples from the property will be scanned using the LIBS instrument to fast-track the identification of anomalous targets, for additional exploration and drill targeting.
