Ann: Maiden Lithium Resource Drilling Nearing Completion, page-4

"The geometry of the pegmatites allows access to near-surface (2-20m)
medium-high grade ore, within current permitted pit design, for initial
production"

@africadale , this is probably the reason why in AMAL's Half Yearly Results (9/02/2017) it mentions Deeper extensional drilling (it's within the current permitted pit design).

"Deeper extensional drilling has commenced on the Bald Hill mining lease, on a nominal 320m x 160m grid. Core drilling also commenced to obtain additional metallurgical samples. The drilling confirmed the continuity of the pegmatites previously mined at Bald Hill some hundreds of metres at depth and along strike beyond the current resource models and identified another thick mineralised pegmatite approximately 30-100 metres below the current AMAL resource model."
