Arizona Lithium Limited provided an update on metallurgical test work currently being undertaken by Hazen Research. Big Sandy Lithium Project (Arizona): The Big Sandy Project, as a very shallow, flat lying mineralised sedimentary lithium resource and with excellent available infrastructure, has the potential to be developed with a very low environmental footprint. Hawkstone's successful 2019 drill program at Big Sandy resulted in the estimation of a total Indicated and Inferred JORC resource of 32.5 million tonnes grading 1,850 ppm Li for 320,800 tonnes Li2CO3 1. This represents 4% of the Big Sandy Project area that contains an estimated exploration target of between 271.1Mt to 483.15Mt at 1,000 - >2,000 ppm Li 2. Note that the potential quantity and grade of the estimated geological potential (Exploration Target) is conceptual in nature.

There has been insufficient exploration to estimate a mineral resource and it is uncertain whether future exploration will result in the definition of a mineral resource. It has been estimated using a range of thicknesses for the mineralised sediments calculated from drill intercepts, surface sampling and geological mapping. The grade estimates a range of values demonstrated from drilling and surface sampling.

In April 2021, a 132kg of lithium mineralised material of ½ core from the 2019 diamond drill programme at the Big Sandy Lithium Project was dispatched to Hazen Research. The ½ core samples were amalgamated and blended by Hazen to provide a uniform bulk sample representative of the mineralised material from the Big Sandy deposit. Samples weighing 0.9 to 1.7 kg, cut from the blended bulk sample, were subjected to beneficiation tests to determine what percentage of the coarser carbonate (acid robbing) material could be removed using attrition scrubbing and hydro-cyclone classification while still providing a significant Li recovery and concurrently lowering the total acid consumption.

A total of 3 beneficiation and comparative screening tests were completed. At the end of each test both the coarse reject and concentrate were analysed to determine contained Li. It was determined that scrubbing and hydro-cyclone classification produced a concentrate nearly doubling the whole ore Li content.

The beneficiated concentrate contained 71% of the original Li and 8% of the original carbonate while reducing the whole ore mass to 36% of the starting mass. This equates to a 64% reduction in the amount of mineralized material requiring processing and in turn reduces the original whole ore acid consumption of approximately 500 kg/mt by 64%. Following the previously described beneficiation process, three samples of the beneficiated concentrate weighing from 0.2-0.32 kg were leached with sulfuric acid to extract the lithium.

Leach tests were completed at varying temperatures of 25, 70 and 80oC, yielding lithium extractions ranging from 85 - 94%. Sulfuric acid consumption ranged from 432 - 490 kg/mt, the equivalent of 155-176 kg/mt for un-beneficiated ore.
