Abstract In this paper the main results of the first archaeological dig in Colombia of a pre-Hispanic goldsmith workshop are presented succinctly; this workshop worked over 800 years in the lower basin of the Saldaña river (Magdalena Valley). Human groups settled there during the late period (9th-17th c. AD) had technical expertise (hammered-annealing, lost wax casting and emptying), tools (refractory ceramic and lithic industry) and forest resources and minerals needed to produce parts in copper and gold high quality, complexity and size (heartlike pectorals, anthropomorphic and zoomorphic figures with tips on bracket).
