Track 3: Environmental Stewardship

322 Table 2 – Average chemical contents by lithology for mafic rocks and gabbros Table 3 – Chemical results for samples collected from basaltic rocks at the N4E mine bench 4.2 Mineralogical Characterization Among the 37 samples analyzed, just one (SSDFD00962AE016) reached 30 wt%, exceeding the equivalent maximum quartz content permitted for soil remineralizer applications of 25 vol% (Figure 3). Overall, the samples show high modal abundances of biotite, chlorite, and K-feldspar, reflecting hydrothermal alteration of variable intensity with a predominantly potassic signature consistent with descriptions reported from the CMP literature.
