Jon Dugdale, Mindoro's CEO, said his company would use IFC advice on following "recognised best practices for the mineral exploration industry, the environment, and for working with local communities." Drilling results this far show limonite intersections with 1.09% nickel and 49% iron; and high-grade saprolite intersections with 1.39% nickel; some smaller cobalt deposits have also been discovered.
report on the differences in particle size, shape, and degree of sorting, and the density of associated clay minerals, in hard subsoils derived from transported (by wind or water) material compared with those derived in situ from saprolite. The hard subsoils were found to contain rounded quartz grains and transported, rounded aggregates of clay (spherites), while saprolite contained angular quartz grains in a more porous kaolin clay matrix.
