Pegmatite Geochemistry: An Insight A sample from an active lithium mine (~3% Li₂O) was analyzed using a handheld XRF and gave the following results: Rb = 4400 ppm, Cs = 263 ppm, Ta = 0 ppm, Sn = 50 ppm, Nb = 6 ppm. Despite coming from a lithium-rich zone, the Ta, Sn, and Nb values are quite low compared to other LCT (Lithium-Cesium-Tantalum) pegmatites observed in Nassarawa State of Nigeria. This suggests that: 1. The Li enrichment may have occurred independently of Ta–Nb–Sn mineralization, poss

17 reactions | Why the Spodumene Contains less Rb compared to pegmatite sampled at surface ? pure spodumene at depth = earlier crystallization = low Rb Surface pegmatite pockets = late-stage enrichment = high Rb #MineralExploration #MiningNigeria #NCGideon #lithiumexploration #lithium | NC Gideon | Facebook

Core Drilling for Lithium (Spodumene) Mineralization Our current drilling operation is focused on testing lithium-bearing pegmatites within a granitic–gneissic terrain. Drilling is being conducted at an inclination of 60° facing west, using NQ-size rods with a maximum drilling capacity of 300 m. The target zone for spodumene mineralization is projected between 25 m and 40 m, based on surface geological mapping and prior structural observations. The host lithologies include granite, granitic gnei
