RPM Hole 4 Drill Core (AN-24-05) at 401 meters depth. Top image: Abundant, visibly disseminated awaruite grains (typically 50-100 microns, with some up to 323 microns). Bottom image: Awaruite grains from RPM DDH004 at 401 meters depth under a microscope, showing grains well above 10-micron size required for effective magnetic separation and recovery.
