Mining Study Confirms Potential for Long Mine Life


  • Initial mining study points towards low-cost open pit mining at Rhyolite Ridge
  • Potential for long-life mining operation at rates of 2 million to 4 million tonnes per annum
  • Based on only the high-grade (lithium-boron) component of the South Basin Resource
  • The Resource is likely to increase substantially with additional drilling outside of the current Resource at both South Basin and North Basin
  • Two stage development being considered:
    • ➢ A 2Mtpa starter pit (constrained) based on 26Mt Resource that may be eligible for fast-track permitting due to its small footprint
    • ➢ A large, unconstrained pit based on 87Mt Resource and sufficient to support 4Mtpa operation
  • The mining study provides the basis for estimating the cost of feed to the processing plant and is an integral part of the Preliminary Feasibility Study currently underway
  • Together with recently announced favorable heap leach results (12/12/17), the mining study supports the potential for low capital and operating costs for the mining and acid-leaching stages of the project
