| Description: OREAS 750 has been prepared from a blend of RC drill chip samples supplied from Core Lithium’s Finniss Lithium Project located in the Northern Territory, Australia, barren granodiorite and quartz. The project area contains the Grants lithium pegmatite deposit, within the Bynoe Pegmatite Field. Lithium-Caesium-Tantalum (LCT) Type pegmatites in the Finniss area intrude Palaeoproterozoic metasediments of the Burrell Creek Formation. Lithium mineralisation typically occurs as coarse spodumene and accessory amblygonite with muscovite, quartz, albite and k-feldspar gangue. The barren granodiorite was sourced from the mafic, S-Type, Late Devonian Bulla Granodiorite complex located in northern Melbourne, Australia.
Seventeen commercial analytical laboratories participated in the program: • Sodium peroxide fusion with full suite elemental package by ICP-OES and/or MS finish
• Lithium borate fusion whole rock analysis package by X-ray fluorescence
• Thermogravimetry: Loss on Ignition (LOI) at 1000°C
• 4-acid digestion for full suite elemental package by ICP-OES and MS finish
