Marquee Resources Limited (“Marquee” or “Company”) (ASX:MQR) is pleased to update the market about the ongoing exploration activities at the West Spargoville Project (“WSP” or “Project”).


HIGHLIGHTS:

  • Results from aircore drilling confirm the presence of Lithium-Cesium-Tantalum (LCT) pegmatites as the source of surficial geochemical anomalism.
  • Large LCT halo (extending over 2km and up to 300m wide) identified in aircore drilling to be followed up with reverse-circulation drilling to test for bedrock mineralisation.
  • Follow-up mapping identifies outcropping, spodumene bearing pegmatite within an interpreted pegmatite dyke swarm.
    10 reverse-circulation drillholes of the 57-hole program completed with drilling initially targeting the interpreted pegmatite dyke swarm.

The company has received results from a 93-hole, 5,470m aircore drilling program, which has confirmed the presence of highly fractionated LCT-type pegmatites as the source of surficial geochemical anomalism. Aircore drilling was completed in the eastern portion of the tenure, where the depth of weathering extends up to 60m deep, with elevated lithium-cesium-tantalum values in weathered material associated with elevated pathfinder elements (Table 1). A large geochemical halo (90th percentile Li > 64ppm) extending over 2 kilometres and up to 300m wide has been identified from the aircore drilling, with the bedrock source to be targeted in follow-up reverse-circulation (RC) drilling.

In preparation for RC drilling further mapping was completed which identified a NE-striking, spodumene bearing pegmatite (Figure 1) in an area considered highly prospective due to the results from auger geochemistry and deep ground-penetrating radar (DGPR) (Refer: MQR ASX Release 21st April 2022). RC drilling has begun to test the NE-striking corridor with multiple pegmatites intersected in drilling thus far. The first batch of samples have been delivered to the laboratory with results expected in 4-6 weeks.

In relation to the disclosure of visual mineralisation the Company cautions that visual estimates of spodumene abundance should never be considered a proxy or substitute for laboratory analysis. Laboratory assay results are required to determine the widths and the grade of visual mineralisation repo

Executive Chairman Comment:

Marquee Executive Chairman, Mr Charles Thomas, commented: “To identify pegmatites with clear LCT geochemical signatures is highly encouraging and confirms the prospectivity of the West Spargoville Project. There had been no lithium exploration completed at the Project 12 months ago so we are making great progress and look forward to keeping the market updated as more results come to light. We are currently systematically exploring the Project with RC drilling continuing for the forseeable future and will begin another round of aircore drilling in the last week of June so it is a very exciting time for the Company.”

Exploration Update & Forward Work Plan

Results have been received from a 93-hole, 5,470m aircore drilling program. The aircore program was completed in the eastern portion of the tenure where there is a well-developed weathering profile up to and beyond 60m deep. As such, the aircore results are from highly weathered material where geochemical dispersion is prevalent. The assay results show a clear LCT-pegmatite association with tantalum concentrated preferentially in the upper saprolite and lithium concentrated in the lower saprolite (Figure 2). Follow-up RC drilling is required to test for the bedrock source of the geochemical dispersion halo. The geological setting is analogous to the Cade Pegmatite at the Dome North Project where mineralised pegmatite is hosted within the Black Flag Beds beneath a well-developed weathering profile (Refer ESS ASX Release 14th January 2022).

RC drilling has begun to test multiple geochemical anomalies detected during the auger program (Refer: MQR ASX Release 21st April 2022). The first drillholes of the program have targeted an interpreted dyke swarm in the vicinity of recently mapped outcropping spodumene-bearing pegmatite dyke (Figure 3). Multiple pegmatitic dykes have been intersected of varying thicknesses (Figure 2), with the first batch of assays at the lab for analysis. Results are expected within 4-6 weeks.
