JRG Energy provided reservoir input to Altamin’s scoping study for a geothermal lithium project at Cesano. The scope included a review of legacy data, estimation of well output and resource longevity, and delivery of a concise technical report chapter suitable for inclusion in the scoping study. Conclusions were supported by calibrated wellbore models. Work was completed to Competent Person standard, compliant with JORC requirements and sufficient to satisfy ASIC reporting obligations for a scoping study level assessment.
