Marquee Resources Limited (“Marquee” or “the Company”) (ASX:MQR) is pleased to provide an update on ongoing exploration works at the Redlings Rare Earth Element Project (“Redlings”), Leonora, Western Australia. Following the completion of a ground gravity survey at the Project (refer ASX release 04 October 2023) the Company has embarked on another auger soil sampling program to further define the extents of surficial REE anomalism interpreted to be related to the intrusion of REE-bearing carbonatite pipes. Historical exploration has focused on NW trending structures, however, the recently acquired gravity data highlighted that the interpreted carbonatite pipes have an NNE trending orientation and the exploration model has been refined accordingly. Company geologists have mapped REE-bearing dykes/veins with varying structural orientations which may represent late- stage carbonatite cone sheets or ring dykes. Drill planning is well advanced with the results of the auger program to provide critical information to best target future drill holes as the Company aims to fully test the potential of the Redlings Project to host an economic REE mineral resource.

Executive Chairman Comment:
Marquee Executive Chairman, Mr Charles Thomas, commented:
“With our significantly improved understanding of the Redlings REE Project we believe we have possibly identified the source of the surficial mineralisation that we have encountered at the Project and are honing our drill plans accordingly.”
“The auger program will be the final step in our data acquisition process before drilling that will be completed in Q1-2024. It’s an exciting phase for the Company and Project and we’re looking forward to completing deep, targeted drilling into the dense pipe-like structures we have identified. We have an exciting pipeline of new exploration activities over the next 12 months, and I look forward to updating all our shareholders and the wider market with further progress at this exciting Project.”
1,218 auger soil samples have been collected as part of a ~2,500 soil sampling program designed to test for surficial anomalism of new targets identified from a recently completed ground gravity survey at the Project. 3D modelling of the gravity data highlighted a complex structural architecture intruded by dense bodies, which are interpreted to represent carbonatite pipes, extending to significant depths. The gravity survey focused on a ~4.9 km x 1.2 km historical geochemical anomaly to assist in interpreting the primary controls on surficial mineralisation. Following the completion of the auger geochemistry program, drilling will be undertaken with holes up to 500m deep aimed to test the pipe like features. The Company aims to fully test the potential of the Project to host an economic REE mineral resource in 2024.

The Redlings Rare Earth Element Project
The Redlings Project (formerly called Jungle Well) is 100% owned by Marquee and comprises exploration licences E 37/1311 and E 37/1376 (Figure 3). The Project is located approximately 40km west of Leonora, and 77km north of Menzies. Lynas Corporation’s Mt Weld Project lies approximately 150km east of the project. The Redlings Project covers an area of approximately 108km2 of tenure with historical rock-chip samples up to 7.8% TREO (see ASX release 18 May 2023).
The Redlings Project is situated over an NNW trending high magnetic biotite-hornblende monzogranite granite that has intruded into the surrounding granite pluton. A series of NW trending faults run obliquely through the granite were targeted historically for REE bearing mafic dykes within the Project. This was due to the identification of the Redlings dyke identified during prior exploration activities. The Company has greatly enhanced the understanding of the Redlings Project through geophysics, geochemistry and drilling and carbonatite intrusions are now interpreted to strike NNE and the Company will use these recent advancements to identify targets for the discovery of additional REE bearing dykes.

Highlights
- First cash of $2 million to be received in Q3, 2024 from gold sales.
- Repayment of $1 million working capital in Q3, 2024.
- Milling notice signed to toll treat 150,000 tonnes of ore.
- Processing to commence 24 July 2024 with campaign to last 6-7 weeks.
- 75,000+ tonnes already delivered to Greenfields Mill or on ROM Pad at mine.
- Further toll milling campaigns scheduled in Q4, 2024.
- JV on target to process 300,000 tonnes at Greenfields Mill in 2024/2025.
Management Comment
Managing Director, Mark English, said:“We’ll bank $2 million this quarter, first proceeds to Auric from the 2024 mining of Jeffreys Find. It’s an early payment from our JV partners, reinforcing to us that we’re in for a great year at Auric.
“With another $1 million coming back from our earlier working capital contribution to Stage 2 at Jeffreys Find, we find ourselves in a robust position.
“The Coolgardie mill has now agreed with BML that it will toll treat 150,000 tonnes of gold ore starting 24 July 2024. This second gold campaign of the year is expected to generate in excess of $20 million in gross revenue for the joint venture, setting the stage for ongoing cash distributions to Auric.
“BML has a contract with the mill to process 300,000 tonnes in 2024, but it will extract considerably more tonnes than that. Discussions are underway as to where this excess tonnage will be toll milled.
“We are exceeding our targets and with the gold price holding around $AUD3,500 an ounce the timing is perfect. Jeffreys Find will be a substantial cash producer for Auric in 2024 and 2025,” said Mr English.

As of 3 July 2024 a total of 43,402 tonnes of ore has been transported to the Greenfields Mill (Greenfields) at Coolgardie by BML Ventures Pty Ltd of Kalgoorlie (BML), Auric’s joint venture partner.
BML is mining around the clock with an estimated 30,000+ tonnes of high grade ore on the ROM Pad at Jeffreys Find, awaiting transport to Greenfields.
Greenfields and BML have executed a toll milling notice to process 150,000 dry metric tonnes of ore. Milling will take place across approximately six to seven weeks, commencing 24 July 2024 and concluding in early September 2024.
BML is planning on mining more than 300,000 tonnes of ore during Stages 2 and 3 of the Project in 2024 with further gold milling campaigns scheduled later in 2024 and early 2025.
Auric has also received notification from BML that it will receive $2 million in cash, being the first distribution of surplus cash for Stage 2 of the Project, this quarter.
In addition BML has advised it will repay $1 million to Auric this quarter, working capital AWJ had advanced to the JV for the commencement of Stage 2 mining at Jeffreys Find.

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.
