Marquee Resources Limited (“Marquee” or “the Company”) (ASX:MQR) is pleased to provide an update of ongoing exploration and targeting activities at the West Spargoville Project (“WSP” or “The Project”). Recently, Company geologists completed further mapping and sampling to better define targets for the planned upcoming drilling programmes. Leveraging off previously acquired geochemical, geophysical and drilling data, the Company has identified a pegmatite swarm with over 40 fertile pegmatites identified with mapping, sampling and portable-XRF (p-XRF) analysis confirming the presence of spodumene in 10 of the individual pegmatites (Figure 2). The recent sampling returned a best rock chip assay of 3.01% Li2O (24WS0010) with numerous results >1% Li2O (Table 1). The Company continues to collaborate closely with Joint Venture Partner Mineral Resources Limited (ASX:MIN) regarding all facets of the WSP Project and the ongoing 2024 exploration campaign.
HIGHLIGHTS:
- Ongoing mapping and sampling has delineated 10 individual spodumene bearing pegmatites at the West Spargoville Project.
- Recent High-Grade rock chip assay results with numerous results >1% Li2O which include:
- 3.01% Li2O (24WS0010)
- 2.76% Li2O (24WS0017)
- 2.60% Li2O (23SW0039)
- 2.36% Li2O (24WS0004) &
- 2.02% Li2O (23WS0047)
- Detailed ground gravity data acquisition complete and data processing underway to target mineralised pegmatite bodies at depth.
- Drilling approvals partially complete with remaining items progressing to allow drilling to commence as soon as possible.
- The Company continues to collaborate closely with Joint Venture Partner Mineral Resources Limited (ASX:MIN) regarding all facets of the WSP Project and the ongoing 2024 exploration campaign.
Exploration Update & Forward Work Plan
The Company has received assay results from 51 whole-rock samples taken during a recent mapping program of the Company’s focus area (Figure 2 & Table 1). An additional 156 p-XRF sample points were also collected from pegmatites to assist in delineating the prospectivity and strike extents of the mapped pegmatites (Table 3). Over ten pegmatites have been identified in the focus area with the tenor of mineralisation varying between the various pegmatites, but also within individual pegmatites. A peak assay from the recent rock chip sampling returned 3.01% Li2O (24WS0010) while historical rock chip sampling previously returned a peak assay of 3.12% Li2O (10686). Multiple assays from rock chip sampling have returned high-grade assays >1.0% Li2O. The controls on the zonation of mineralisation are currently not fully understood with further work required to determine the controls on the location of high-grade mineralisation.
In conjunction with the recent mapping and sampling, p-XRF mapping program was undertaken to increase data density and assist in further delineation of fertile pegmatites. The use of a handheld p-XRF, while no substitute for whole-rock geochemical analysis, is standard industry practice and an effective and dynamic targeting tool used in LCT-pegmatite exploration. p-XRF data can be used to identify and assess granitic parent rock fertility with respect to the hosting potential of LCT pegmatites and can differentiate potential rare metal-bearing pegmatites from barren, more typical pegmatites with granitic composition. When used in conjunction with whole-rock analysis, the p-XRF can assist in mapping fertile vs barren pegmatites at a fraction of the price and in a fraction of the time. When assessing granitic parent rock fertility, fertile granites exhibit elevated Rb, Cs, Sn, and Ta, as well as lower K/Rb ratios than typical granites. From analysis of whole-rock assay data Company geologists note:
- Where the sampled pegmatite contains economic mineralisation (>1.0% Li2O), the K/Rb ratio is <10.
- However a K/Rb <10 in whole-rock assay data does not always correlate directly with economic lithium mineralisation.
Although the whole-rock assay data highlights the limitations of using the K/Rb in LCT-pegmatite exploration, correct application of both the p-XRF and K/Rb ratio can be an effective targeting tool to delineate more- prospective vs less-prospective pegmatites.

The Company also wishes to advise the market that it has completed a ~3,900 station, highly detailed ground gravity survey over the priority focus area. The detailed gravity survey is designed to aid in targeting the mineralised pegmatites at depth. The hypothesis is that the mapped pegmatites may converge and blow-out at depth and the gravity survey will assist in identifying the controlling structures to mineralisation. Data processing is now underway, with the results of this to be released once completed.
The Company is currently working through the approvals process to complete drilling over the main focus area. The Program of Work (PoW) has been approved by DMIRS, whilst liaison with the Native Title party to complete a Heritage Survey is still ongoing. The Company will update the market once all approvals have been received.

- 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 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.
