Mineralisation:
OREAS 752 has been prepared from RC drill chip samples supplied from Core Lithium’s Finniss Lithium Project located in the Northern Territory, Australia. 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. 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
