Gravity Survey Identifies New High Density Structures At The Redlings REE Project

Marquee Resources Limited (“Marquee” or “the Company”) (ASX:MQR) is pleased to announce that it has completed a 1,907 station ground gravity survey at the Company’s Redlings Rare Earth Element Project (“Redlings” or “the Project”). The gravity survey was designed to test for deep-seated carbonatite intrusions and to identify the potential source of surficial rare earth element (REE) anomalism of up to 7,503ppm TREO previously encountered at the Project (Refer ASX announcement 18 May 2023).


  • Ground gravity survey completed and successfully identifies high-density pipe-like structures.
  • Gravity data highlights NNE trending, pipe-like structures which significantly enhances the exploration model.
  • The pipe-like structures are interpreted to be the primary source of surficial values of the REE mineralisation with previous results up to 7,503ppm TREO.

Final data processing and 3D modelling has been completed with results of the survey highlighting 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 geochemical anomaly to assist in interpreting the primary controls on surficial mineralisation. Although historical exploration has focused on NW trending structures, the gravity data has highlighted that the interpreted carbonatite pipes have a NNE trending orientation and the exploration model needs to be refined and shifted to focus on these NNE trending structures. Company geologists have mapped REE-bearing dykes/veins with varying structural orientations which may represent late- stage carbonatite cone sheets or ring dykes. Following the completion of the gravity survey, further mapping and auger geochemistry is planned with deeper reverse circulation drilling to follow. The Company aims to fully test the potential of the Project to host an economic REE mineral resource.

Executive Chairman Comment:

Marquee Executive Chairman, Mr Charles Thomas, commented:

“This infill gravity survey has significantly improved our understanding of the Redlings REE Project. For the first time, we believe we have possibly identified the source of the surficial mineralisation that we have encountered on our last few exploration campaigns at the Project.”

“Acquisition of this new geophysical datasets is a significant next step in unlocking the potential of the geology within the Redlings REE Project area. An exciting pipeline of new exploration activities will now follow over the next 12 months at the Project. I look forward to updating all our shareholders and the wider market as we make further progress at this exciting Project.”

The Redlings Rare Earth Element Project

The Redlings Project (formerly called Jungle Well) is 100% owned by Marquee and comprises exploration licenses E 37/1311 and E 37/1376 (Figure 4). 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 (refer to ASX announcement on 11 November 2020).

The Redlings Project is situated over a 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 which 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.

Western Australia Allocates AU$14 Million to Improving Environmental Approval Process

Western Australia's governmentsaid on Monday (November 11) that it is allotting AU$14 million to support the employment of additional staff at the Environmental Protection Authority (EPA) and the Office of the Appeals.

The boost comes in response to the Vogel-McFerran Review commissioned by the government in 2023. It recommended various steps to speed up the state's environmental approval system and secure major projects.

According to the government, employing additional staff will help address existing backlogs and provide faster decisions “without impacting the high standard for protecting WA's unique environment.”
