Lithium occurs as Spodumene in pegmatites in the Georgia Lake area. The pegmatites are hosted by metasediments. All of the pegmatites are Albite-Spodumene type. Spodumene is the dominant Li-bearing mineral in all of the pegmatites.
Overall, the pegmatite dike internal zonation increases in complexity from north to south within the Georgia Lake pegmatite field:
• Nama Creek – the Main Zone North (MZN) and Main Zone Southwest (MZSW) have simple zonation: aplite or granitic border zone and a Spodumene zone with minor alternating aplite and pegmatite layers.
• Harricana (HAR), Line 60 (LIN60), and Conway (CON) have aplite or granitic border zone, a Spodumene zone and common alternating aplite and pegmatite layers.
The mineralization in the Property consists of coarse-grained fresh pale green spodumene crystals, oriented perpendicular to the strike of the pegmatite dike in homogeneous dikes, and randomly oriented within the inner spodumene zone in simply zoned pegmatite dikes. The spodumene may be altered to muscovite or fine-grained muscovite near the contacts with the host rocks and near diabase dikes.
The altered spodumene has low lithium content and a high iron content.
Nama Creek
The Nama Creek area holds most of the resource on the Georgia Lake Property within four pegmatite dikes. These dikes are: MZN, MZSW, HAR, and LIN60. Several other dikes have also been identified in the area and include Kenogamisis, Line 2 ........
