The Zoro Dyke 1 metallurgical program investigated the feasibility of lithium beneficiation by dense media and dry magnetic separation with the goal of producing a 6% Li2O concentrate from a Master Composite, at a fairly coarse particle size of -12.7/+0.5 mm. Completed heavy liquid separation (“ HLS”), DMS and dry magnetic separation test work confirms that HLS demonstrates excellent potential for the recovery of an on-spec lithium concentrate from the Master Composite by dense media separation. For Phase one of the project, the results of which were released in December of 2022, the HLS and DMS (dense media separation) test work concluded Dyke 1 spodumene mineralization is amenable for production producing a final spodumene concentrate assaying 5.93% Li2O, with a lithium recovery of 66.9% in 26.5% mass after magnetic separation. For Phase two of the project, the results of which was released in March of 2023, the DMS and flotation of DMS Middlings together achieved a global lithium recovery of 81.6% at a spodumene concentrate grade of 5.88%, demonstrating that our spodumene concentrate is capable of producing both battery grade lithium products, lithium carbonate (Li2CO3) or lithium hydroxide (LiOH), while returning an extremely favourable OPEX/CAPEX to our Company.

Chain of Custody, Quality Control and Quality Assurance, and Data Verification

Drill core for assay purposes was sawn in half after logging and core mark-up by the Company’s geologist. Samples were collected based on an appropriate sample interval and washed to remove mud from cutting the core with the core saw. The core sample was placed into a clear plastic bag and the sample number written on the bag. An assay tag was inserted into the sample bag, one tag was inserted into the core box marking the sample location and the third tag was retained in storage. All core samples were placed into a white vinyl pail with a sample inventory, labeled and stored in a locked facility until enough samples were available for shipping. At this point the sample pails were taken to the local shipping company and loaded into a sealed transport truck. A bill of lading was signed by the geologist after the number of sample pails were counted and the shipping address confirmed. Receipt of the sample pails was acknowledged by the assay laboratory. Blanks, duplicate samples, and internal standard reference materials were included with each sample
