  abstract = {{T}his work aims to elucidate the factors governing the mobility of metals in soils of a lateritic nickel ore deposit in {N}ew {C}aledonia. {T}he transfer of nickel and associated metals is determined along a topographic sequence ranging from a plateau to a thalweg. {M}ining exploration borehole data and soil pit data enabled us to define the general geochemical trends of the lateritic weathering. {T}he homogeneous topsoil, which consists mainly of iron oxy-hydroxides, exhibits various amounts of plant available metals. {T}wo interrelated factors control the differences in metal availability: (1) the presence of nickel-rich soil horizons underlying the topsoil and formed of silicate minerals, and (2) the biological cycling of metals from these horizons to the surface. {T}hese results have major implications for topsoil management during the mining activity where it is important to minimise metal inputs to water systems and to restore endemic vegetation after mining.
