The 36-year evaluation history of the AK1 lamproite of the Argyle diamond mine (1980–2016) captures an important chapter in the development of diamond deposit evaluation. The resource potential was recognized early in the evaluation process, despite indications of a fine diamond size-frequency distribution and lower-quality stones. High diamond density and the size-frequency distribution characteristics allowed development of sampling methods. These included large-diameter core sampling and analysis of 20-kg samples of NQ/split HQ core for microdiamonds, which were significantly cheaper than traditional methods and unique to the diamond industry at the time. These methods permitted increasingly deep evaluation programs that...
