[eng] From a dust rain that took place in the urban nucleus of Palma on May 5, 2017, we describe for the first time the presence of a particular type of golden spherules accompanied by copper flakes along with mud spherules already known since 1983. One of the components of these spherules are copper flakes (which also present small zinc needles). They have been detected on 39 occasions in observations made since 1979, apart from the dust spherules already registered since 1983. Although it has been observed that Cu flakes are always linked to dust rains, we have not been able to recognize when they are incorporated into the African dust cloud. Until now the golden spherules have been found only in one occasion, which only have a formal resemblance to the classical mud spherules.
