“…Tistl y Salazar (1994)). It's crucial to underscore that, apart from this remarkable discovery, the economic and social significance of platinum holds prominence, both in the history of Colombia and on a global scale (as explored in McDonald y Hunt, 1982;Lane, 2011;Aristizábal-Fúquene, 2015).…”

“…In the latter half of the 18th century, the platina had transitioned from a political matter to a subject of scientific intrigue on the European continent (Aristizábal-Fúquene, 2015). The introduction of platinum to Europe can be linked to two significant events: the writings of Ulloa, as previously mentioned, and the influx of platinum specimens originating from the illicit slave trade passing through New Granada via Jamaica (Lane, 2011, and references therein).…”

In Colombia, after nearly 500 years of the quest for the platinum source rock, a remarkable discovery of a fossiliferous limestone with gold and platinum now resides under the watch of the Geological Survey's Museum in Medellín, registered as RS 2.2.1.1.3. Platinum group minerals, long sought after in Colombia's placer deposits since the 19th century, typically found in the form of nuggets, have received special attention due to the missing link that exists between authigenesis in mafic/ultramafic rocks to detrital alluvium associations. Consequently, this finding unveils an entirely new environment hosting platinum. In this article, we delve into the historical context and the heritage value of a sample boasting 300 g/t of platinum and 33 g/t of gold, embedded in a dolomitized biosparite. Various analyses, encompassing atomic absorption spectroscopy, X-ray diffraction, micropetrographic characterization, and scanning electron microscopy coupled with energy-dispersive spectroscopy, were performed on the sample. The sample baffled experts due to its unassuming sedimentary rock appearance and the unusual circumstances of its arrival at the museum. Hence, it stands as one of those uncommon scientific curiosities with an unforeseen origin, accessible only through a stroke of chance and an unbiased perspective regarding its origin. Beyond its historical and geological significance, this specimen, safeguarded within the museum's collection, encourages education and awareness regarding geosites, advocating for the preservation of one of the planet's most biologically diverse regions, where platinum was first discovered.

“…When Ulloa y Juan (1748) unveiled the high platinum content in Chocó and Barbacoas, an issue emerged concerning the platina's impact on the Royal Mint of Bogotá (see excerpt from Book VI, Chapter ingots). This conundrum, aptly termed "the platina problem", was viewed as a threat to the Royal Treasury (Lane, 2011;Aristizábal-Fúquene, 2015). The Pinto's platina, purportedly discovered in the Pinto River within the Province of Popayán-a region to which Chocó was once attached (Espinosa Baquero, 1986)-was considered an impurity that tainted the gold (Cano Borrego, 2016).…”
