dc.description.abstractThe genesis of gold placer deposits is related to different superficial processes, having varied characteristics and complex mechanisms of mineral concentrations. They are often exploited by medium to small-scale miners, with high geological uncertainty and/or without proper geological characterisation. This represents a difficulty for mineral resource estimation, and usually simpler geometric methods are employed. The Cordón Baquedano Gold Mining District (CBGMD) in southernmost South America has been a source of detrital gold for over a century. Some attempts of industrialised mining occurred but without success. Furthermore, the existing metallogenic models are over 30 years old and do not represent the complexity and variety of the deposits found in the district. This research follows the common practices for mineral inventory estimation to create a resource model for the Mina Nueva Deposit (MND) in the CBGMD. Mineralisation and resource models are proposed by using traditional and geostatistical methods. The results of this study indicate that the gold resources in the MND varies from 8,070 to 10,730 ounces using newly acquired dataset, and from 16,720 to 18,280 ounces for a database that incorporates new and historical information. This illustrates the great complexity and variability of results when estimating mineral resources within placer gold deposits in this area.
