Even though plunderers were still present, archaeological investigations of the Hacienda Malagana cemetery were attempted in March 1993, but had to be discontinued after only a few days. The Malagana Treasure of the Colombia, South America, is the group of gold and other artifacts plundered in 1992 in a mob \"gold rush\" after an ancient cemetery near Hacienda Malagana in western Colombia, was discovered in 1992. Later that year, some of the artifacts were donated to the Museo del Oro Museum of Gold in Bogotá. Archaeological excavations at the site established a new cultural complex, designated as Malagana, that dates between 300 BC to AD 300 . A radiocarbon date of AD 70 plus or minus 60 (uncalibrated) was obtained from the debris inside the pottery vessel. After the site had finally been abandoned by the treasurer hunters, more extensive excavations were conducted late in 1994.
