Lithium-bearing pegmatite dykes represent a significant source of lithium for global markets. Over the past decade, SRK Consulting has conducted numerous studies, disclosure of mineral resources, and due diligence reviews on Li-pegmatite deposits around the globe. SRK has noted that the geological assessment of these hard rock Li sources shares common features, gaps, and challenges. Successful resource risk assessment requires the evaluation of dyke mineralogy, textures, and chemistry along with overall dyke geometry, continuity, internal dilution, and cross-cutting features which directly impact project viability and resource classification. In additional, most pegmatite projects require detailed structural geology assessment, geometallurgical domain characterization, tight-spaced diamond drilling, and 3D modeling at deposit-scale to provide sufficient detail for successful mine planning, metallurgical assessment, and economic assessment for project viability.
