Alchemy Resources Limited (ASX: ALY) (“Alchemy” or “the Company”) is pleased to provide an update on its exploration activities at the 100% owned Bryah Basin Project in Western Australia. Recent work has confirmed the Valley Bore prospect target is highly prospective for Iron Ore. Mapping and sampling by Alchemy in 2008 and 2009 discovered high grade hematite and banded iron outcrops over 2km in strike and up to 66.3% Fe+1 & 2. Recent rock-chip sampling by Alchemy returned similar high grades up to 65.9% Fe. Alchemy believes the combination of high-grade outcropping hematite mineralisation on a granted mining lease near major roads and infrastructure highlights the significant near-term development potential of the project.
HIGHLIGHTS
- Significant high grade iron ore enrichment identified on Alchemy’s Bryah tenement package. Alchemy owns 50% of iron ore rights via wholly owned subsidiary Alchemy Resources (Three Rivers) Pty Ltd.
- High grade rock-chip assays from Valley Bore return grades up to 64.9% Fe with Calcined Fe grades up to 67.4% Fe.
- Total strike length of multiple mapped BIF ridges exceeds 2,000m with new regional areas recently identified with grades up to 65.9% Fe which could extend this further.
- Southern Ridge Target high grade hematite outcrops range from 10m to 80m thickness over a 900m strike.
- Planning for drill testing of the high-grade iron formations underway.
- Alchemy remains well funded with cash on hand of $3.5m as at 31 March 2024.

Chief Executive Officer Mr James Wilson commented: “Iron ore rock-chip grades above 58% Fe are very encouraging and highlight the DSO potential of the project. It’s an exciting opportunity with our leases surrounded by majors in the sector such as Sinosteel Midwest Corporation to the south. Hematite outcrops are evident over a 900m strike extent at the Southern Ridge target, and we have high grade rock-chip assays from new areas 3km away, so there’s a lot of potential to grow the project. Furthermore, Alchemy has identified a second iron ore occurrence at Old Highway Prospect which has the potential to add further scale. With its proximity to the Great Northern Highway and its advanced Mining Permit status, the Company believes there’s a significant opportunity to rapidly advance this asset in the near term.”

Jindalee Lithium
Overview
Jindalee Lithium (ASX:JLL,OTCQX:JNDAF) is an Australia-based exploration and development company advancing North America’s largest lithium deposit. After a spinout of its Australian assets, Jindalee has become a pure-play lithium company focused exclusively on its promising 100-percent-owned McDermitt project. Jindalee recognises the vast opportunity for lithium projects in the US as the country progresses towards its sustainable energy transition and developing a robust domestic supply chain for critical minerals.
As the US strives to transition to clean energy, demand for lithium will continue to increase as this critical mineral is necessary to achieve the country’s net-zero goals. With its favorable mining policies and infrastructure, the US actively supports the advancement of new projects to strengthen its domestic supply chain.
Jindalee’s McDermitt asset, located in southeast Oregon, contains a unique type of lithium mineralisation. Most lithium projects in North America are lithium brine or pegmatite deposits; however, the McDermitt project is an unconventional sediment-hosted lithium asset.
Sediment-hosted lithium deposits such as McDermitt are long-life assets with low strip ratios and low mining costs. Jindalee can leverage this advantage over other lithium assets, both in terms of reaching production faster and reducing operating expenses.
There is currently no commercially operating sediment-hosted lithium project in North America. Two recently announced projects, however, are under development and demonstrate McDermitt’s future trajectory as both companies move toward production.
The 2023 mineral resources estimate (MRE) for McDermitt contains a combined indicated and inferred mineral resource inventory of 3 billion tons at 1,340 parts per million (ppm) lithium for a total of 21.5 million tons (Mt) lithium carbonate equivalent (LCE) at 1,000 ppm cut-off grade. At 21.5 Mt LCE, McDermitt is the largest lithium deposit in the US by contained lithium in mineral resource, and a globally significant resource, with the deposit remaining open to the west and south.
In June 2023, Jindalee commenced a pre-feasibility study (PFS) on the McDermitt Lithium Project appointing Fluor Corporation as lead engineer. The company expects completion of the PFS by mid-2024. Jindalee also announced initial metallurgical results from acid leaching of the beneficiated samples of McDermitt ore. Lithium extraction from composite samples averaged 93 percent (250 micron (µm)) and 94 percent (75 µm) while lithium extraction from all units exceeded 98 percent with higher acid additions.
An experienced management team, with the right blend of experience and expertise in geology, corporate administration and international finance, leads Jindalee to fully capitalise on the potential of its assets.
Company Highlights
- Jindalee Lithium is a pure-play lithium exploration and development company focusing on its flagship McDermitt lithium project, currently the largest lithium deposit in North America.
- The United States has ambitious electrification goals but lacks the critical minerals to reach them. Jindalee aims to strengthen the North American supply chain to enable the country to reach net-zero emissions targets.
- Globally, most of the lithium is currently sourced from either pegmatite or lithium brine deposits. The company’s McDermitt deposit, however, is sediment-hosted, an emerging style of lithium deposit with the potential to be a long-life, low-cost source of lithium.
- There are presently no sediment-hosted lithium assets in North America that have reached production. Jindalee is ideally positioned to help fill this void in the market.
- Other companies in North America are moving towards production, and their progress indicates Jindalee’s future trajectory.
- An experienced management team leads Jindalee towards capitalising on the potential of its assets.
Key Project
McDermitt Lithium Project
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. Following positive results from its 2022 drill campaign, the resource at McDermitt has increased to 21.5 Mt LCE, making McDermitt the largest lithium deposit in North America.
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.
- Resource Increased by 62 percent early 2023: Compilation of the 2022 drilling results saw the estimated indicated and inferred resources at McDermitt increase to 3 billion tons at 1,340 ppm lithium, a 62 percent increase in contained lithium. The updated resource released by the company contains a combined indicated and inferred total of 21.5 Mt LCE at 1,000 ppm cut-off grade.
- Memorandum of Understanding (MOU) with POSCO Holdings: Jindalee entered into an MOU with POSCO Holdings (NYSE:PKX), under which POSCO will fund metallurgical testwork on McDermitt ore and undertake joint research for the asset. POSCO is partnering with General Motors to supply cathode active material (including lithium) for its electric vehicles.
- 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.
- Highly encouraging metallurgical testwork: Results from beneficiation and acid leaching tests have exceeded expectations. Beneficiation testwork completed in late 2023 (on sample representing a nominal life-of-mine average feed) recovered 92 percent of the lithium to leach feed and rejected 25.3 percent of the mass at a cut size of 250 µm. Additionally the acid leach test work announced in early 2024 demonstrated very high lithium extraction rates on beneficiated ore. Specifically, the calculated lithium extraction for a composite sample using 250 µm leach feed was 92.9 percent which compares favourably with the extraction rate (94 percent) achieved through testwork from the finer (75 µm) leach feed using 500 kg/t acid. Further testwork is now underway.
- PFS in progress: Jindalee has appointed Fluor Corporation to commence the PFS for McDermitt, set to be completed by mid-2024.

Unconformity Uranium Drill Targets Identified from 2024 Geophysical Data
Key Highlights
- Final data received and interpretation completed for the ground electromagnetic geophysical surveys from the winter 2024 program at the Marshall and North Millennium projects.
- Several conductive anomalies identified at Marshall, located above and below the unconformity, consistent with regional exploration model.
- Stacked anomalies concurrently with multigenerational geophysical data provides a base to assess the exploration targets and refine drillhole targets.
- The projects are located 15 kilometres from the majority Cameco owned Millennium deposit, and just 40km from the world class McArthur River mine.
- Basin remains funded for the next round of field exploration.
The ground electromagnetic successfully identified 3 main targets which confirms the geological and exploration model. Of note is Target 1 (Figure 1), where modelled EM plates below the unconformity align with a sandstone ZTEM anomaly, which is interpreted to be alteration within sandstone. The identification of these targets is encouraging and consistent with regional trends in the southeastern Athabasca and provides increased confidence in drill hole targeting. Basin is currently reviewing options and priorities of how to progress exploration of these confirmed targets.
Basin’s Managing Director, Pete Moorhouse, commented:
“Conducting ground geophysical surveys on Marshall and North Millennium was a milestone in advancing these underexplored projects in Basin’s uranium portfolio. The form of these anomalies is highly encouraging given the proximity to some of the world’s largest uranium deposits.”
Key results
Following the encouraging conductive anomalism highlighted by the 2023 3D inversion of two historic airborne Electromagnetics (Z‐Tipper Axis) (“ZTEM”) datasets partially covering the current North Millennium and Marshall projects3,4, Basin contracted Discovery International Geophysics5 to carry out ground Stepwise Moving Loop Transient Electromagnetic (‘Ground EM’) surveys on areas of immediate interest within the Projects.
Figure 1 Three main anomalies shown from 2024 ground EM, in plan view (top diagrams) and cross- section looking northeast (bottom diagram). The ground EM anomalies are displayed with the modelled plates against the historical ZTEM data.
The 2024 Ground EM survey data returned six conductive anomaly picks producing three main target areas (Figure 1). The anomalies correlate strongly with the southern edge of the circular ZTEM conductive anomaly at Marshall and the interpreted northern edge of the circular anomaly identified in the historic data. A weaker EM pick was also interpreted centred between the two prominent ZTEM conductivity anomalies.
Three-dimensional modelling using Maxwell produced six electromagnetic conductive plates within the basement stratigraphy, all below the unconformity (Figure 1). The two southeastern plates are clearly aligning with a conductive sandstone ZTEM anomaly identified from the historic data, which is above the interpreted unconformity. This is interpreted as potential basal sandstone alteration proximal to the EM anomalies and constitutes a high-priority drill target area, refer figure 2.

Airborne EM over Multiple Targets on Ti-Tree Project
- Augustus Minerals has contracted UTS Geophysics to conduct a VTEM Max survey over several Copper, Cu-Ni-PGE, Zn-Pb-Ag and Uranium targets along the money Intrusion and within proximity of the prospective 85k long Ti-Tree Shear.
- The surveys will cover:
- The Money Intrusion, prospective for Cu-Ni-PGE mineralisation.
- Copper Ridge and Nics Bore over anomalous Copper Drilling results
- The Coo Creek prospect where drilling by Augustus in 2023 identified strongly anomalous Zn-Pb-Ag mineralisation.
- The Munaballya Well North area which shows potential for economic Uranium mineralisation.
- The surveys will help to advance the untapped potential of the Ti-Tree project to host economic mineralisation of multiple commodities.
Andrew Ford, GM Exploration
“The VTEM survey will provide key targeting data over three highly prospective and different prospects with potential for multiple commodities. Whilst the high prospectivity for copper mineralisation has been well documented, the addition of uranium and Broken Hill base metal style mineralisation highlights the quality of the underexplored Ti-Tree project”.
VTEM
UTS Geophysics has been engaged to conduct a helicopter borne VTEM Max survey comprising 646-line km over three separate survey areas. The system is excellent for locating discrete conductive anomalies as well as mapping lateral and vertical variations in resistivity which helps map structure, alteration and rock type. The system also collects magnetic data through a caesium magnetometer. The transmitter/receiver loop is suspended on a cable approximately 40m below the helicopter (Figure 1).
Figure 1 VTEM Max helicopter deployed electromagnetic survey arrangement.
Figure 2 Prospects and VTEM Survey areas.
Money Intrusion
The Money Intrusion, which has proven potential to host Ni-Cu-Co-PGE (platinum group elements), is part of the regional Mundine Well Dolerite Suite, a regionally extensive dolerite (strike length >80km). This extensive mafic intrusion, which is comprised of a variety of lithologies, including gabbro in the core, olivine dolerite on the chilled lower contact or keel and fine-grained dolerite on the outer edges. Mapping, aeromagnetics and multi-spectral imagery show that the Money Intrusion within the Ti-Tree Project covers a strike length greater than 16km, reaching widths >600m in the north of E09/23241.
