Here's another with a better cash cost despite lower grade. Perhaps a better DLE process.
Hub City Lithium Corp. PEA results for the Viewfield oil field brine project in Saskatchewan, Canada.Koch absorption DLE together with Saltworks refinery technologies into an average 12,175 tpa lithium carbonate facility operating over 23 years. The relevant inferred resource grade averages 128 mg/L Li, ranging from ~200 mg/L to ~100 mg/L Li by end of project.The project’s capital cost is estimated at US $571M, operating costs US $3,319/t LCE. Using a flat long-term price of US $20,000/t LCE, the NPV8% comes in at US $1.07B post-tax. Adamas Intelligence note: "Koch Technology Solutions is fast becoming to go-to technology provider scoped for North American oil field brine projects. Although expensive to build, the projected operating cost estimates of Viewfield are very competitive resulting in a 45% project IRR."
