Manganese mineralization related to levels of Liditas at the base of the Carboniferous, being originally in the form of carbonates (rhodochrosite); subsequently, by processes related to contact metamorphism, reaction of the primary carbonates with the quartz of the Liditas, a series of manganese silicates formed and later, by alteration, Mn oxides, which were the subject of mining.
In addition to the manganese mineralization are observed minerals from Ni, Co, Sb, Te, and As in the form of small aggregates of sulphides and sulphosalts in the Liditas.

The former exploitation we call generically "Serrana" mine, while in fact these are two different farms, with two separate dumps, one for the "Serrana" mine itself (with horizontal workings), while the other (the most next to the river and vertical workings) would be the mine known as "Manganese." The "Serrana" mine is located some 2.5 km south of El Molar, along the river Siurana; the mining was on manganese oxides resulting from the weathering of Mn-silicates.

Antigua explotación que denominamos genéricamente como mina "Serrana", si bien de hecho se trata de dos explotaciones diferentes, con dos escombreras separadas, una correspondiente a la mina "Serrana" propiamente dicha (con trabajos horizontales), mientras que la otra (la más próxima al río y con trabajos verticales) sería la conocida como mina "del Manganeso". La mina "Serrana" se halla a unos 2,5 km al sur de El Molar, junto al río Siurana. En la mina Serrana se intentaron explotar los óxidos de manganeso, producto de la alteración de los silicatos.
