Alchemy Resources Limited (ASX: ALY) has completed its first pass, project wide regional reconnaissance at the 100% owned Lake Rebecca Project in Western Australia.
The company has also received the results from a targeting review by Lithify Pty Ltd on the tenement package. The outcome of the study showed that Lake Rebecca is highly prospective with regional scale flexures on both the Keith Kilkenny and Claypan shear zones and proximity to nearby large scale >1Moz gold deposits.
The review focussed on generating “camp scale” prospective areas for follow-up based on structural and lithological criteria. The study outlined seven target areas for lithium exploration and five target areas for gold exploration.
A recent reconnaissance visit discovered the presence of pegmatites and granite dykes in the region, which require additional mapping and follow-up. No exploration for lithium has been undertaken historically on the Lake Rebecca tenements.
Lake Rebecca have never been explored for lithium and have had very little exploration.
“This review is a great outcome and highlights the prospectivity of the Lake Rebecca tenements,” CEO, James Wilson, said.
“Targets in the north of of any kind historically. Near term we are looking forward to conducting further reconnaissance exploration to determine if the numerous granite bodies and mapped pegmatites and other felsic dykes in the region display fertile chemistry for Lithium-Caesium-Tantalum (LCT) mineralisation.
“We aim to piggyback our gold exploration in tandem with this work. The structural review reaffirms the exceptional prospectivity of our large tenement package for LCT mineralisation at Lake Rebecca in what has historically only ever seen gold and base metals exploration.”
The Lake Rebecca Project includes seven granted exploration licences and three applications covering 570 sq. km of Archean greenstones in the Eastern Goldfields of Western Australia. The Project is located 100km east of Kalgoorlie in a highly prospective geological setting, covering greenstones, numerous internal granites and known gold bearing structures. It is located just 10km southeast of Northern Star Resources Carosue Dam deposit, and 6km west of Ramelius Resources Rebecca deposit.
Previous explorers around the Lake Rebecca area have primarily undertaken gold and base metal exploration, including BHP Minerals, Newmont, Renaissance Minerals and Troy Resources from 1960-1990, and more recently St Barbara. Gold exploration has seen wide, ~800m spaced aircore drill lines along the Keith- Kilkenny and Claypan major structures in the southern areas with very little drilling completed in the northern tenements.
Several gold targets were generated by field mapping consultants for St Barbara in the northern tenements in 2013 which have never been tested. Pegmatites were mapped during a traverse in the north, but the areas were never sampled. Geological Survey of Western Australia (GSWA) mapping was completed in 1990-1991 and several granite dykes and pegmatites were mapped throughout the area. Lake Rebecca has never been explored for lithium previously.
Current Activities
Alchemy has completed a targeting review by Lithify Pty Ltd on the Lake Rebecca tenement package. The outcome of the study showed that Lake Rebecca is highly prospective with regional scale flexures on both the Keith Kilkenny and Claypan shear zones with proximity to nearby large scale >1Moz gold deposits.
Alchemy geologists conducted a reconnaissance visit to Lake Rebecca in late November 2022. Multiple feldspar rich granite dykes were mapped throughout the tenement package adjacent to small regional granite intrusions within the interpreted Goldilocks Zone for pegmatite formation, and a coarse-grained quartz-feldspar pegmatite was noted during the recent field reconnaissance visit.
Next Steps
• Progress access agreements with the Native Title Groups to enable access into the areas around the northern tenements.
• Additional reconnaissance mapping and sampling of lithium and gold targets to identify prospective areas for follow-up soil sampling and aircore drilling.
