Flynn Gold (ASX:FG1) reports ‘encouraging’ Ultra-fine Fraction (UFF) soil sampling results have been returned at the Mount Dove Project, located 25km north-northwest of the Wodgina Lithium Mine.
Follow-up soil sampling and geophysics programs are currently being planned.
The company reports 11 lithium anomalies have been identified within exploration licence E45/5055. A high priority lithium anomaly over 1200m x 400m has also been identified with coincident pathfinder trace element (Sn-Rb-Ce) anomalism. There is also anomalous gold geochemistry potentially coincident with intrusive margins and structural trends.
UFF soil sampling is a new exploration technique developed by LabWest Minerals Analysis in conjunction with CSIRO as a more sensitive method to explore for minerals including gold, lithium and nickel under transported cover. The UFF technique analyses only the sub-2 micron fraction of a soil sample, and hence the results from UFF assays may not be directly comparable to results from a conventional coarser fraction sample.
Flynn Gold notes in total 497 ultra-fine fraction soil samples were collected during the program. Exploration licences E47/3888 and E45/5055 were covered with a broad, 400 x 400m spaced grid, with more detailed sampling (400 x 200m) along the southern boundary of E45/5055.
Flynn Gold notes Mount Dove is situated 34km west-northwest of the Pilgangoora Lithium Mine and 12km to the southwest of De Grey’s (ASX:DEG) Hemi gold deposit, in the Pilbara region of Western Australia where the largest known lithium deposits are hosted by lithium-caesium-tantalum (LCT) pegmatites.
Addressing the results, Chief Executive Officer Neil Marston commented: “The company’s first exploration activity for lithium and gold has been completed at our Mount Dove Project in the minerals-rich Pilbara region of Western Australia.
“We are very pleased with these ultra-fine soil sampling results as several lithium anomalies have been identified to follow-up, including a 1.2km long, high priority target, which may represent a lithium-pegmatite association.
Follow-up geophysical assessment and in-fill sampling will be undertaken at Mount Dove ahead of further exploration of this largely un-explored project.
“Flynn has secured a significant land holding in Western Australia with several of our recent tenement applications located close to world-class lithium deposits”
Flynn has secured a significant land holding in Western Australia with several of our recent tenement applications located close to world-class lithium deposits. We have recently initiated historical data collection and desktop geophysical studies on these projects so that as the tenements are granted, we can commence field work, exploring for lithium and other battery metals, without delay.”
The geology of the Mt Dove project is predominantly obscured by transported alluvium and soil cover varying up to 20-25m thick. However, significant geological and geophysical evidence of large granitic plutons underlying the cover exists and the results from this UFF soil sampling survey suggest that the granitic rocks at Mt Dove have the potential to be fertile for pegmatitic type lithium deposits. Mafic rocks have been recorded subcropping in the northern portions of Exploration Licence E45/5055.
