Amazon is currently seeking opportunities to further develop additional partnership agreements to aid in the projects progress.

Subsequent Period Summary

• Bench scale agronomic tests are being completed using ThermoPotash that has been processed at the company's pilot plant. Initial solubility tests using concentrated nitric acid have shown the process has succeeded in making 95.8% of the contained potassium (K₂O) soluble and potentially available to plant roots in trial versions of the fertilizer product, made from the insoluble verdete rock.
• Lab scale tests are advancing on the generation of muriate (KCl), sulphate (K₂SO₄) and carbonate (K₂CO₃) of potash from our verdete ore.
