Alchemy Resources Limited (ASX: ALY) (“Alchemy”) is pleased toannounce an exploration update for its Karonie and Lake Rebecca Projects (WA).
HIGHLIGHTS
- Lithium focussed gravity survey completed at Cherry, Hickory, Mesquite and Pecan Prospects. Data processing underway with results expected in March.
- Project wide regional soil geochemical sampling commenced on high priority lithium and gold targets at Karonie and Lake Rebecca.
- High resolution drone magnetics commenced on priority lithium gravity anomalies at Hickory and on regional gold targets at Karonie.
- Access agreements and programs of work submitted to facilitate upcoming drill programs.
Project wide soil sampling has commenced on the high priority Karonie and Lake Rebecca lithium targets aiming to cover the Roe Hills and Manhattan Prospect areas, which sit immediately to the west and east and contiguous with Global Lithium Resources’ (ASX: GL1) Manna deposit prospects. Soil sampling will also be undertaken on the Lake Rebecca Prospects, which showed prospective “Goldilocks Zone” geology after Company geologists conducted a site visit in November 2022.
Gravity data collection at the 5.4km x 1.6km corridor towards Pecan has been completed with data processing in progress. Drone magnetics has also commenced in this area to assist in targeting on the Hickory gravity corridor, as well as additional zones being flown on potential gold bearing structures to the south of Silver Lake Resources’ (ASX: SLR) Aldiss Mining operations.
Chief Executive Officer Mr James Wilson commented: “We are pleased to complete the larger gravity survey at Hickory with the aim of mapping the pegmatite structures over a large area towards Pecan. In tandem with this, the high resolution drone magnetics over this area will provide additional layers of detail to assist with drill targets. We are also kicking off regional soils programs which will give us a broader picture of lithium anomalism surrounding the Manna Project at Alchemy’s Roe Hills Prospect to the west and our Manhattan Prospect to the east, as well as lithium prospective areas at Lake Rebecca to the north. At the same time we continue to progress gold exploration with the high resolution drone magnetics to the south of Silver Lake’s Aldiss Operations which will give us near term targets to test.”
CURRENT ACTIVITIES
ROE HILLS PROSPECT SOIL SAMPLING
Roe Hills lies along a distinctive structural trend from the Pegmatite field that hosts the Manna Lithium deposit (32.7Mt @ 1.0% Li2O1) 5km to the north-east. GSWA mapping has identified a high density of narrow plagioclase dykes, porphyritic dykes and quartz veins mapped adjacent to the granite contact zone. Multi-element soil sampling conducted by Alchemy in 2018-2020 highlighted multiple areas of low-level lithium anomalism and coincident pathfinder anomalism across a broad strike extent. Mapped dykes appear to have a parallel north-south strike extent, parallel to the greenstone/granite contact, however most of the area around the known mapped dykes are covered by alluvium and it is likely that these areas are far more extensive than the known outcrops. Soil sampling programs were originally targeting gold mineralisation and as a result, coverage of the prospective areas is limited.
The current soil sampling campaign at Roe Hills is aimed at gaining a complete dataset on the western side of the Cardunia granite adjacent to the Manna lithium deposit. First pass soil sampling completed in 2019 identified several lithium pathfinder anomalies and this program is aimed to extend and infill these anomalies.
MANHATTAN PROSPECT SOIL SAMPLING
The Manhattan prospect sits immediately east of GL1’s Manna project. Alchemy conducted shallow RAB drilling for gold exploration in 20182 which intersected coarse grained fractionated dolerites in proximity to the regional granite contact. The area has seen no modern exploration for lithium and only limited exploration for gold despite being located along the Claypan shear which extends up towards Breaker Resources’ Lake Roe gold deposit (1.7Moz3) nearby. Multi-element soil sampling is designed on a 400m x 400m offset grid to test for lithium pathfinder anomalies adjacent to the buried granite that lies underneath Lake Roe. No lithium targeted exploration has been undertaken around the Lake Roe area previously.
LAKE REBECCA SOIL SAMPLING
The Lake Rebecca Project includes seven granted exploration licences and three applications covering 570km² of Archean greenstones in the Eastern Goldfields of Western Australia. The Project is located 110km east of Kalgoorlie in a highly prospective geological setting, covering greenstones, numerous internal granites and known gold bearing structures. It is located just 10km southeast of Northern Star Resources’ (ASX: NST) Carosue Dam deposit (4.3Moz4), and 6km west of Ramelius Resources’ (ASX: RMS) Rebecca gold deposit (1.2Moz5).
Alchemy geologists conducted a reconnaissance visit to Lake Rebecca in late November 2022. Multiple feldspar rich granite dykes were mapped throughout the tenement package adjacent to the small regional granite intrusions within the interpreted Goldilocks Zone for pegmatite formation. A coarse-grained quartz-feldspar pegmatite was seen during the recent field reconnaissance visit.
Soil sampling is designed to test for lithium anomalism on a 400m X 400m offset grid. This program is targeting areas where known amphibolite facies metamorphic grade rocks occur, which are the ideal conditions for Lithium-Caesium- Tantalum (“LCT”) pegmatites to form. Previously no exploration for lithium has occurred at Lake Rebecca and Alchemy expects this to be the first of several lithium targeted exploration programs.

Jindalee Lithium
Investor Insight
Jindalee Lithium’s flagship McDermitt Lithium Project (McDermitt) offers investors exposure to a generational, high-margin critical minerals asset. The recently completed Pre-Feasibility Study (PFS) demonstrates robust economics, positioning McDermitt as a key enabler of North America's clean energy transition and a cornerstone of the US critical minerals strategy to de-risk supply chains through increased domestic production.
Overview
Jindalee Lithium (ASX:JLL,OTCQX:JNDAF) is a pure-play lithium company with a strategic focus on the United States. Its 100 percent-owned McDermitt Lithium Project is the largest lithium deposit in the US, boasting a resource of 21.5 million tons (Mt) of lithium carbonate equivalent (LCE).
Backed by a recently released (November 2024) Pre-Feasibility Study (PFS) demonstrating very compelling economics, McDermitt is poised to play a crucial role in meeting North America’s growing lithium demand for battery materials.
As the US continues to transition to clean energy, demand for lithium is expected to exponentially increase. Jindalee’s McDermitt project, located in southeast Oregon, is a game-changer for North American lithium supply, critical for meeting the demands of a fast-growing electric vehicle and renewable energy industries with specific emphasis on developing and de-risking domestic supply chains.
McDermitt also stands to significantly benefit from the US government’s policies and incentives to boost domestic supply of critical resources. In fact, in a move that signifies the US government's support of the McDermitt Project, the US Department of Energy's Ames National Laboratory signed a Cooperative Research and Development Agreement (CRADA) with Jindalee's subsidiary HiTech Minerals to develop cutting-edge extraction methods for McDermitt. Under this agreement the US Department of Energy (DOE) will fund work aimed at reducing costs and improving sustainability outcomes for the Project. The Ames National Laboratory spearheads the DOE's Critical Materials Innovation Hub. Jindalee is also advancing an application for a grant from the US Department of Defense, which has the potential to co-fund a feasibility study and associated work programs at McDermitt.
Key milestones in the US lithium resource space also provide significant insights into the future prospects for McDermitt. Lithium Americas’ (TSX:LAC), has received a US$945 million commitment from General Motors, to fund the development, construction and operation of the Thacker Pass project in Humboldt County, Nevada, located 30km away from and in the same geological formation as Jindalee’s McDermitt Lithium Project. LAC has also closed a $2.3 billion US Department of Energy loan in late 2024 to fund approximately 75 percent of the construction capital cost (US$2.93B).
Another lithium resource developer in Nevada, Australia-based Ioneer (ASX:INR) is expected to receive a total investment of US$700 million through a new joint venture with Sibanye Stillwater, in addition to a conditional loan commitment of US$650 million from the US Department of Energy, both acting to strengthen the development of its flagship Rhyolite Ridge lithium-boron project.
In late 2024, ASX-listed company Patriot Battery Metals Inc (ASX:PMT) announced a C$69 million investment, strategic partnership and offtake agreement with global automotive group Volkswagen which aims underpin the development of Patriot’s upstream lithium project in Quebec, Canada.
These are just a few examples of current market dynamics that point to rapidly accelerating lithium resource development in the US and Canada demonstrating the investment appetite of strategic partners, as well as support from the US government via low-cost concessional debt funding.
An experienced management team, with the right blend of experience and expertise in project development, corporate administration and international finance provides Jindalee with the leadership to fully capitalise on the potential of its assets.
Company Highlights
- Jindalee Lithium is focused on its wholly owned flagship McDermitt Lithium Project, currently the largest lithium deposit in the US
- A PFS for McDermitt – delivered in November 2024 - supports very strong project economics, including a US$3.23 post-tax NPV and a 5 year capital payback period over a 63 year project life
- Jindalee’s McDermitt Lithium Project seeks to assist in the development of US critical minerals supply chains to enable America to meet its energy security and electrification goals
- Jindalee’s wholly owned US subsidiary HiTech Minerals has executed a strategic Cooperative Research and Development Agreement (CRADA) with the US Department of Energy (DOE) as part of the DOE’s Critical Materials Innovation (CMI) Hub
- McDermitt is located in the same geological formation and is of similar size and scale to Lithium Americas’ Thacker Pass Project, which is backed by major investments from General Motors and the US Department of Energy and is currently under construction
- McDermitt is eligible for a wide range of government incentives including tax credits, grants and concessional loans. Jindalee is currently progressing a grant application with the Department of Defense to potentially co-fund a feasibility study at McDermitt
- In collaboration with lead engineer Fluor, Jindalee has produced battery grade lithium carbonate from McDermitt’s lithium bearing ore in metallurgical testwork.
- Experienced management team is focused on maximising the potential of Jindalee’s assets.
Key Project
McDermitt Lithium Project Economics
The economic metrics revealed in the PFS paint a compelling picture of the McDermitt Lithium Project's potential:
Production Capacity: The Project is set to produce 1.8 Mt of battery-grade lithium carbonate over its first 40 years, with an annual output forecast of 47,500 tonnes per annum (tpa) in the initial 10 years, and averaging 44,300 tpa over the first 40 years.
Financial Metrics: The Project boasts a post-tax net present value (NPV) of US$3.23 billion at an 8 percent discount rate, with an internal rate of return (IRR) of 17.9 percent. These figures underscore the Project's strong economic viability.
Payback Period: Investors can expect a payback period of less than five years, a relatively short timeframe for a project of this magnitude.
Robust margins: Exceptional EBITDA margins of 66 percent over the first 10 years of operations, with C1 costs in the bottom half of industry and 17 percent pre-tax net operating cashflow margins (including sustaining capital) at current bottom of the cycle spot prices (October 2024 spot of US$10,888/t of lithium carbonate)
Significant future upside. Several opportunities identified in the PFS have potential to significantly enhance returns, which includes process optimisation to reduce opex/capex as well as potential for production of by-products. Additionally, there remains significant optionality to further exploit the ore body, with only ~15 percent of the current resource included in the PFS schedule (on contained metal basis).
The PFS estimates a total project cost of US$3.02 billion, which includes a conservative 21 percent contingency provision estimated on P70 basis (70 percent probability total capital cost will be lower), prepared by US headquartered global engineering and construction firm, Fluor Corporation. This substantial investment is expected to provide the platform for a long life, stable supply of domestically sourced battery grade lithium chemicals, which is expected to be highly attractive to partners in the battery value chain.
Project Overview
The McDermitt Project is located in Malheur County on the Oregon-Nevada border and is approximately 35 kilometres west of the town of McDermitt. The 100-percent-owned asset covers 54.6 square kilometres of claims at the northern end of the McDermitt volcanic caldera.
The Project is characterised by its unique sedimentary lithium deposits, primarily composed of lithium-bearing clays, a geological formation that sets McDermitt apart from many other lithium projects worldwide. This sedimentary nature of the deposit offers several advantages, including:
- Consistent grade distribution throughout the ore body
- Potential for large-scale, low-cost mining operations
- Amenability to environmentally friendly extraction methods
The lithium-rich clays at McDermitt are part of a broader geological context that includes volcanic tuffs and sedimentary rocks. This geological setting is indicative of a complex depositional history, which has resulted in the concentration of lithium in economically viable quantities.
The 2023 mineral resources estimate (MRE) for McDermitt contains a combined indicated and inferred mineral resource inventory of 3 billion tonnes at 1,340 parts per million (ppm) lithium for a total of 21.5 Mt LCE at 1,000 ppm cut-off grade. As part of the PFS, a maiden ore reserve estimate was declared of 251 @1,761 ppm Lithium for 2.34 Mt LCE (representing only ~11 percent of MRE)
Project Highlights:
- Rare Sediment-hosted Lithium Deposits: The McDermitt asset supports low-cost mining operations due to its flat-lying sediments. This type of lithium deposit is amenable to low-cost mining operations, while still producing excellent metallurgical results.
- Low cost mining. Ore is soft, free-digging material, located at surface with a strip ratio of only 1.3 over project life. As a result mining costs are relatively low.
- Fluor recommended processing route: In March 2023, US engineering group Fluor reviewed all testwork undertaken at McDermitt and recommended beneficiation and acid leaching as the optimal processing route (similar to that used by more advanced peers in the region).
- Battery-grade lithium carbonate successfully produced: Process flowsheet was validated through PFS test work program, which produced battery grade lithium carbonate in July 2024. This is an important milestone validating all steps of the processing flowsheet for the Project from ore beneficiation and leaching to purification and production of battery-grade lithium carbonate.
- High metallurgical recovery. PFS test work demonstrated exceptional recoveries through beneficiation and acid leaching steps, with an average metallurgical recovery of 84.4 percent over first 40 years, comparing favourably to industry peers.
