Project Highlights

  • District-scale land package positioned as Utah’s leading claystone lithium project
  • Lithium mineralized claystones as well as lithium in brine potential
  • Similar geology to Nevada’s hotbed of activity in the Clayton Valley – Tonopah area
  • On site company testing facility set up with LIBS analyzer for faster project advancement

Project Overview

Rockland’s Utah project is comprised of two properties located 185 km south-west of Salt Lake City. The project is road accessible and has excellent regional infrastructure with power, rail and nearby communities. Both properties are located in Juab County, Utah and are interpreted to be prospective for lithium claystone and brine mineralization.

Lithium Butte


The Lithium Butte property is situated 185 kilometres southwest of Salt Lake City and hosts claystone volcanic tuff breccia units interpreted to be highly prospective for lithium (Li), beryllium (Be) and rare earth mineralization. Summer 2022 sampling returned up to 4,080 parts per million lithium (ppm Li) from a grab sample, while channel sampling returned 25.2 metres at 1,388 ppm Li, including 8.0 metres at 2,155 ppm Li and 0.7 metre at 3,540 ppm Li. Multiple prospective targets have been indicated.

Fish Springs

The Fish Springs property is comprised of both mineral claims directed at claystone lithium mineralization and placer claims focused on lithium brine targets.

In summer 2022 a total of 2,285 soil samples were taken over Rockland’s land positions. Soil samples were tested using a handheld Laser Induced Breakdown Spectrometer (LIBS) for lithium and beryllium at the company facility in Delta, Utah by Rockland personnel. After a significant lithium-in-soil anomaly was identified on the Fish Springs property, a total of 151 soil samples were selected and sent into the laboratory for validation. The results confirmed the existence of a 4km by 9km lithium-in-soil anomaly and validated the results from LIBS testing. The lithium is hosted in clay-rich lake sediments covering most of the Fish Springs property. The identification of this soil anomaly is a significant step forward in advancing this green fields project.

Exploration Targets

Rockland continues to evaluate the extent of claystone lithium mineralization in both properties:

  • Geological mapping has identified Li and Be enriched volcanics and Li enriched lake sediments
  • Utah Geological Survey has identified Fish Springs as having Li-brine potential
  • Over 1,000 soil samples from Lithium Butte and 1,400 soil samples from Fish Springs have been collected
  • Rock and soil samples continue to be rapidly analyzed at Rockland’s testing facility in Delta, Utah with the state-of-the-art Laser Induced Breakdown Spectrometer analyzer
