18 | AcmeLabs Schedule of Services & F ees 2013 Rock & Drill Core Soil, T ill & Sediment Lithogeochemical Whole Rock Major & T race Element Analysis Gr oup 4 NILA T F or Nick el-Laterite Exploration and evaluation of nickel laterite requires total determination and mass balance accounting of the major rock-forming elements and the commodity elements Ni, Cu and Co. Acme delivers these requirements with Group 4A-7TD that combines a cost ef fective whole-rock determination and a total- digestion, multi-element assay . The package contains four separate analytical tests that report 23 parameters (11 major oxides, 10 minor and trace elements, loss on ignition and SUM). SUM is the sum total of these con - stituents that gives a mass balance close to 100% when all the major constituents are accurately determined and accounted for . The redundancy of two separate Ni determinations (Group 4A and Group 7TD) provides an additional check on accuracy . Samples must be dried (prep method D105) prior to analysis.
