Marquee Resources Limited (“Marquee” or “the Company”) (ASX:MQR) has commenced a ground gravity survey at the Company’s Redlings Rare Earth Element Project. The gravity survey aims to test for deep-seated carbonatite intrusions to identify the potential source of surficial rare earth element (REE) anomalism up to 7,503ppm TREO (refer ASX announcement dated 19 May 2023).
- Ground gravity survey has commenced to test for deep-seated carbonatite intrusions.
- Gravity survey aims to identify source of surficial values up to 7,503ppm TREO associated with previously unrecognised REE-bearing dykes.
- Auger geochemistry previously identified a 4.9 km x 1.2 km zone of REE anomalism.
The ground gravity survey will consist of 1,908 survey stations over the Redlings Project extents and is expected to take approximately 2 weeks to complete. The gravity survey is focused on a ~4.9 km x 1.2 km geochemical anomaly with results of the survey to be used to further delineate drill targets (Figure 1). Company geologists have recently mapped REE-bearing dykes/veins with varying structural orientations which may represent late-stage carbonatite cone sheets or ring dykes. The ground gravity survey aims test for possible deep-seated, carbonatitic intrusion(s) for follow-up drill testing. In conjunction to the gravity survey further mapping and auger geochemistry is being planned to further understand the potential of the Project to host an economic REE mineral resource.
Executive Chairman Comment:
Marquee Executive Chairman, Mr Charles Thomas, commented:
“We are excited to have commenced the next phase of exploration at the Redlings REE Project. Ground-gravity has proven to be a direct targeting tool for REE deposits in the past, and we are confident that our survey will provide us with compelling targets for our next phase of drilling later in 2023.”
“I look forward to updating our shareholders on the progress and results of the survey as they come to hand.”

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 1). The Project is located approximately 40km west of Leonora, and 77km north of Menzies. Lynas’s Corporation’s (ASX:LYC) Mt Weld Project lies approximately 150km east of the Project. The Redlings REE Project covers an area of approximately 108km2 of tenure with historical rock-chip samples up to 7.8% TREO.
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 and are interpreted to be the controlling structures on the emplacement of REE bearing mafic dykes within the Project. Currently, only the Redlings dyke has been identified during prior exploration activities, however numerous parallel structures are observed in the magnetics data and form prospective structural targets for the discovery of additional REE bearing dykes.
