Jindalee Lithium (ASX:JLL)

Battery-Grade Lithium Carbonate Produced from McDermitt

Jindalee Lithium Limited (Jindalee, the Company) is pleased to announce that battery-grade lithium carbonate has been successfully produced from ore from the McDermitt Lithium Project (the Project) (Figure 1). This marks an important milestone, with all steps of the processing flowsheet for the Project from ore beneficiation and leaching to purification and production of battery-grade lithium carbonate now validated (Figure 2).


HIGHLIGHTS:
  • First production of Battery-Grade Lithium Carbonate (>99.5%) from test work completed at Hazen Research Inc. in collaboration with Fluor - lead engineer for the PFS underway at the McDermitt Lithium Project
  • Production of Battery-Grade Lithium Carbonate marks a major milestone with all steps of the McDermitt flowsheet now validated
  • Flowsheet for McDermitt is very similar to Lithium Americas’ Thacker Pass Project currently under construction 30km to the south of McDermitt
  • Results will support the PFS, due for release in Q4 CY 2024
These findings, together with other recently identified value optimisation opportunities, will be incorporated in the Pre-Feasibility Study (PFS) currently underway and due for completion Q4 2024.

Jindalee’s CEO Ian Rodger commented:

"The successful production of battery-grade lithium carbonate from McDermitt ore is a major milestone for Jindalee. This achievement substantially de-risks our processing flowsheet and demonstrates the potential for McDermitt to supply high-quality lithium chemicals to the expanding US battery value chain.

We have been greatly encouraged by the exceptional results we have achieved since commencing the PFS metallurgical test work program with Fluor and Hazen in mid-2023 and anticipate that these results will meaningfully support the outcomes of the McDermitt Lithium Project PFS which is now due for release in Q4 CY 2024.”

Discussion

After investigating various alternatives, in March 2023 acid leaching with beneficiation (see Figure 2) was selected as the preferred flowsheet for the Project2. This decision followed a review of prior test work and high-level benchmarking of five comparator lithium projects by the global engineering, procurement, construction and maintenance company Fluor Corporation (Fluor), which indicated that acid leaching with beneficiation was expected to produce the best economic outcome for the Project. The resultant McDermitt flowsheet (Figure 2) is very similar to that utilised and extensively validated by Lithium Americas Corporation (TSX: LAC) at its Thacker Pass project, which is currently under construction and is also located in the McDermitt Caldera (~30km south of the McDermitt Lithium Project).

Fluor was subsequently appointed as lead engineer for the McDermitt PFS in June 20233, including managing an extensive bench scale metallurgical test work program at Hazen Research Inc. in Colorado, USA, aimed at validating the preferred flowsheet and providing data to inform the PFS (PFS Test Work). To date Jindalee has announced exceptional results from the McDermitt PFS Test Work including results from beneficiation test work in November 20234 and acid leaching in January 20245. Respective highlights include:

  • Beneficiation: Beneficiation of a composite sample of McDermitt ore using attrition scrubbing (250μm cut-size), recorded 92.0% Li recovery with 25.3% mass rejection, demonstrating the excellent potential to remove acid consuming material and increase the Lithium grade of leach feed4.
  • Acid Leaching: Excellent lithium (Li) extraction rates were achieved from sulphuric acid leaching of beneficiated McDermitt ore. Li extraction from composite samples averaged 93% (250μm) and 94% (75μm) using 500kg sulphuric acid per tonne of leach feed5.

Subsequent to the acid leaching test work described above, an additional 300 kg composite sample (250 µm, comprising Units 4, 6, 8, and 10) was leached, yielding lithium in solution (leachate) for downstream test work (post-leach process steps – see Figure 2). The purification of the lithium-rich solution was successfully completed, resulting in the first production of battery-grade lithium carbonate, assaying 99.8% Li₂CO₃ with acceptable levels of deleterious elements in accordance with a typical third-party contract specification. This achievement significantly de-risks the Project by demonstrating the effectiveness of all process steps of the flowsheet at bench scale. Reaching this milestone provides strong validation of the flowsheet developed for McDermitt.

Game-changing, economically significant lithium resource for North American battery supply chain

Resolution Minerals Ltd  To Develop U.S. Government Engagement Strategy with Clewett Global Services

Resolution Minerals Ltd To Develop U.S. Government Engagement Strategy with Clewett Global Services

Adelaide, Australia (ABN Newswire) - Resolution Minerals Ltd (ASX:RML) (FRA:NC3) (OTCMKTS:RLMLF) is pleased to announce the selection of Clewett Global Services as external affairs advisers to support the development of the Horse Heaven Antimony-Gold-Silver-Tungsten project in Idaho, USA.

Highlights

- Engagement in Washington D.C. is a critical step in positioning RML as a trusted partner in the U.S. critical minerals supply chain

- Resolution to consider applying for U.S. Department of Defense (DOD) funding to expedite Horse Heaven Project in Idaho

- Neighbouring Perpetua Resources (PPTA.NAS) was fast-tracked for development in April 2025, and received up to US$74 million in DOD funding, highlighting strong U.S. Government commitment and support for antimony and other critical metal projects

- By aligning with U.S. Government strategic priorities, RML is actively enhancing its ability to progress Horse Heaven on a faster schedule

- Antimony, Silver, Gold and Tungsten trading at record-high prices

CLEWETT GLOBAL SERVICES APPOINTED TO WORK WITH RESOLUTION TO DEVELOP U.S. GOVERNMENT ENGAGEMENT STRATEGY

The Horse Heaven Project is located directly adjacent to NASDAQ-listed Perpetua Resources' $2 billion Stibnite Gold and Antimony Project, which recently gained final record of decision approval from the U.S. Forest Service.

Horse Heaven has strong gold, antimony and silver mineralisation in two highly prospective structurally controlled mineralised corridors, and includes past-producing antimony, tungsten and gold mines.

Historical exploration results from Horse Heaven are highly encouraging and indicate similar geological characteristics to the neighbouring Stibnite project.

Given the importance of antimony to the U.S. Government's critical minerals strategy, Resolution Minerals is excited to develop the Horse Heaven Project and will be actively seeking the support of the U.S. Government to expedite its progress.

Founding Partner of Clewett Global Services, Todd Clewett, is a seasoned external affairs executive with a track record of success in engaging decision makers in Washington D.C. regarding mining and critical minerals projects. Clewett formerly headed up the external affairs function for both Newmont Corporation and Fortescue.

Background

The U.S. government has prioritised domestic and allied sources of key minerals such as antimony, tungsten and gallium recognising their importance to defense applications and renewable technologies.

Until now, the U.S. has relied mainly on China for the supply of many critical metals. Following China's total ban on exports of these metals to the U.S. in late 2024, a priority of the new Administration is to shore up its own domestic supply chains of these materials.

Fast-41 Program

The FAST-41 program, established by Title 41 of the Fixing America's Surface Transportation Act (FAST Act), is a program designed to improve the timeliness, predictability, and transparency of the federal environmental review and permitting process.

FAST-41 is designed to streamline and expedite the permitting process for infrastructure and mining projects deemed nationally significant. FAST-41 can offer benefits to project developers, including increased predictability, transparency and faster decision-making.

Some projects currently covered under FAST-41 include:

- Perpetua Resources' (PPTA.NAS) Stibnite Gold Project in Idaho

- Stillwater Palladium & Platinum Project in Montana

- Jindalee Resources' (ASX:JLL) McDermitt Lithium Project in Oregon

- BPH and RIO's Resolution Copper Project in Arizona

- South32's (ASX:S32) Hermosa Critical Minerals Project in Arizona

Resolution Minerals' efforts to participate in the FAST-41 program follow the precedent set in April this year by next-door neighbour, NASDAQ-listed Perpetua Resources (PPTA.NAS), whose Stibnite Gold Project in Idaho became the first mining project accepted under FAST-41, and by ASX-listed Jindalee Lithium Limited (ASX:JLL), whose McDermitt Lithium Project in Oregon was also successfully fasttracked under FAST-41 in April.

2025 Budget Reconciliation Bill ('Big Beautiful Bill')

The proposed 2025 Budget Reconciliation Bill includes US$2.5 billion to support U.S. production of critical minerals via the National Defense Stockpile. In addition, there is US$500 million allocated to the Department of Defense Credit Program for loans, loan guarantees, and technical assistance aimed at developing reliable sources of critical minerals - both within the U.S. and among key international allies.

Congress is expected to pass this bill (in some form) by the end of July 2025. Resolution has commenced plans to pursue all its available options to apply for funding that may become available upon passing of this proposed bill.

Resolution is considering opportunities under the U.S. Department of Defense's Title III and Industrial Base Analysis and Sustainment (IBAS) programs, which support the development of reliable and resilient supply chains for critical minerals.

RML's Executive Director, Aharon Zaetz commented:

"We are extremely honoured for Todd Clewett to want to work with us. We feel very excited that he shares the enthusiasm for the Horse Heaven project and sees the massive potential here. Todd's experience in working with governments to develop mining projects will be an invaluable asset to RML.

Todd's experience, knowledge and network in the White House provides him with an extremely rare and unique skillset that RML shareholders are extremely privileged to benefit from.
