First Results from Metallurgical Testwork at Mcdermitt Lithium Project

Jindalee Resources Limited (Jindalee, the Company) is pleased to advise initial head assay results have been received for metallurgical samples from Jindalee’s 100% owned McDermitt Lithium Project in Oregon, USA (McDermitt, Project).


  • Head assays received for McDermitt metallurgical samples being tested at Hazen (US) and managed by Fluor
  • Head assays average 1790 ppm Li, 34% higher than average McDermitt resource grade (Indicated and Inferred) of 1340 ppm Li1
  • Benefication currently underway expected to further increase head grade prior to acid leach testwork

These samples average 0.179% Li (1790 ppm) (Table 1), 34% higher than the average grade of the current McDermitt Indicated and Inferred resource grade of 0.134% Li (1340 ppm)1, suggesting excellent potential to process shallow, higher grade ore early in the mine life, with positive implications for Project economics.

Discussion

In March 2023 Jindalee announced that global engineering, procurement, construction and maintenance (EPCM) company Fluor Corporation (NYSE: FLR) (Fluor) had reviewed metallurgical testwork undertaken at McDermitt and had determined that acid leaching with ore beneficiation (to upgrade the leach head grade) delivered the lowest operating costs and best financial outcome among the alternatives considered2.

Fluor also noted that the very large Mineral Resource at McDermitt (21.5 Mt LCE, Table 2)1 allows flexibility in development, providing the opportunity to optimise mining and feed higher grade ore early in the mine life and recommended that a comprehensive metallurgical testwork program be undertaken to provide information upon which the preferred flowsheet for the processing of McDermitt ore can be defined.

Jindalee’s geological team has recently relogged all holes drilled at McDermitt and this work has resulted in the recognition of up to 12 distinctive stratigraphic units which can be tracked across the Project (Figure 2). Four of these units (Units 4, 6, 8 and 10) carry elevated lithium grades and selective mining of these units has the potential to deliver higher grade material for processing.

In June 2023 leading mine engineering group Cube Consulting generated conceptual pit shells using the McDermitt MRE geological model (Figures 1 & 2) to assist with selection of samples for the metallurgical testwork program, which is being managed by Fluor3. Samples from Units 4, 6, 8 and 10 within the Indicated portion of Pit Shell 5 (nominal 20 years) were selected and approximately 700kg of drill core was despatched to consultant metallurgists Hazen for testing, with initial results from this work now being reported.

Arizona Lithium Updates Development Plan for Prairie DLE Facility, Outlines Modular Approach

Arizona Lithium (ASX:AZL,OTCQB:AZLAF) provided an update on development plans for its Prairie lithium brine project, saying the Saskatchewan-based asset will be brought into production in three phases.

The company said on February 6 that Phase I will involve the start of production at Pad #1. It will use a commercial-scale direct lithium extraction (DLE) unit that can produce 150 tonnes of lithium carbonate equivalent annually.

The goal is to process brine at about 1,000 cubic meters a day to ensure the system works under real conditions. Arizona Lithium said it will use the resulting product to de-risk end market opportunities.

Stardust Power Signs Lithium Offtake Deal with Sumitomo Corporation

Stardust Power (NASDAQ:SDST) has signed a non-binding offtake agreement with Sumitomo Corporation, a major trading company headquartered in Japan, for up to 20,000 metric tons per annum of battery-grade lithium carbonate.

“This is a huge milestone for our company, having an offtake partner such as Sumitomo, a very credible and prestigious organization,” said Roshan Pujari, founder and CEO of Stardust Power. “And they can provide a lot of value add other than just acquiring the product — they can help with our marketing efforts.”

Under the agreement, Sumitomo will have the option to buy up to 20,000 metric tons of battery-grade lithium annually, which represents 80 percent of Phase 1 and 40 percent of the total annual capacity of Stardust’s planned lithium refinery.

Rio Tinto, Eurodia Team Up for Argentina Lithium Extraction

Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO) has selected French engineering firm Eurodia to supply the industrial extraction unit for its Argentine lithium subsidiary Rincon, which holds the Rincon lithium project.

Rio acquired the Rincon asset from Rincon Mining in March 2022. The property is located in the Lithium Triangle in Argentina’s Salta province, which hosts more than half of the world’s lithium reserves.

According to an initial mineral resources and ore reserves report, released in December, Rincon's mineral resources, inclusive of ore reserves, stand at 1.54 million tonnes of lithium carbonate equivalent in the measured category, with 7.75 million tonnes in the indicated category and 2.29 million tonnes in the inferred category.
