A prospector was a job within the mining industry that some inhabitants of the galaxy held. In the High Republic Era, the designation "prospector" gained another meaning, referring to hyperspace prospectors, also known as hyperspace surveyors, who were dedicated to the discovery and mapping of new hyperspace routes. Among the many prospectors of that time was Radicaz Dobbs. Prospectors also worked on planets such as Tatooine. There was a period when several prospectors thought that the mineral bene could be located at Plibene Rock.
During the High Republic Era, a period defined by extensive exploration, prospectors journeyed across the Galactic Frontier. Saretha von Beel, a prospector, conducted her operations from Black Spire Outpost on Batuu around 382 BBY. The Grafs together with the San Tekkas were two families known as hyperspace prospectors. The Nihil and her family made use of Mari San Tekka's talent for finding the Paths, which were unconventional hyperspace routes.
Dexter Jettster, a Besalisk prospector, discovered Kaminoan saberdarts while prospecting on Subterrel sometime before the Clone Wars.
