The state prosecutor in the trial of five people accused of a million-dollar gold theft in Western Australia's Goldfields has described the nature of their dealings as "nefarious" and "surreptitious".

In his closing address on day 12 of the trial, prosecutor Paul Usher walked the 14-member jury through the state's evidence against the five accused, which includes WA mining executive Patrick Rhyan Keogh.
