Trigg Minerals Limited announced positive Brine Assay and BMR Results from Lake Throssell. 29 brine samples have been assayed from exploration air-core drilling and monitoring bores screened in the basal aquifer as part of the 2022 exploration field season. The potassium grade results range from 4,260 mg/L to 4,970 mg/L K, with an average of 4,549 mg/L, consistent with the low variability of the deposit.

Results from the screened sections of basal aquifer were between 4,330 mg/L and 4,500 mg/L, which is consistent with the previous air-core assay results from depth, validating the brine sampling approach of exploration drilling to date. Results confirm the consistency of brine grades across the Lake Throssell deposit. Borehole magnetic resonance (BMR) geophysical logging was completed on three monitoring bores to measure in-situ porosity, specific yield and estimate hydraulic conductivity across the resource profile and assist with test production bore planning.

BMR logs have provided unrivaled resolution on the formation porosity, permeability and lithological aspects of the Lake Throssell deposit. Sand zones of the Basal Aquifer are shown to measure specific yield from 0.2 to 0.22 on average which is aligned with the current Resource value of 0.19 on average for the Basal Aquifer. All of the data from the 2022 exploration campaign will contribute towards an upgraded Mineral Resource Estimate (MRE) for Lake Throssell, targeted for later this month.
