The Obdulia concession, nº 24532, was registered by Enrique Fernández Alberdi in the Oviedo Mining Office on July 27, 1940, and it was given that name because the owner's wife was called Obdulia Zaballa Uribe, which was quite common in mining claims in those days. Immediately afterwards, the mine began operation, as before the Spanish Civil War, Celestino Llaneza and Federico Otlet Dewolf had carried out some development on the site, which suddenly stopped due to the war.
The death of Enrique Fernández Alberdi in 1943 left the mining operation in the hands of his family. Works went on intermittently for a five-year period and eventually, in 1949, the mine was sold to the company Importación de Minerales S.A.E. This was led by Ángel Pérez de Leza. This company was to become the parent of Fluoruros S.A., the last and main company that carried out fluorspar mining in this concession.
Along with Melfonso shaft, the Obdulia Mine was one of the most important of all the mines operated by this company in the Caravia area. This statement is subject to the unusual geological features of the area, such as the presence of wide karst regions that caused significant ore deposits, reaching up 30 m of width. On the other hand, the occurrence of local faults, that were the cause of the mineralization, allowed other work near to the main vein that gives its name to this mine.
The mineral extraction was made through a shaft located in the headwaters of the Esplón stream. This shaft was deepened in the mid-50s. The mining was carried out through two galleries corresponding to the 30 and 60 floors and the mineral was transported using horses within these cross galleries and was then lifted to the shaft entrance using a primitive tub-cable mechanism. The works of this underground mine finished completely in 1978. Basically, this closure was due to the lowering of the costs of open cast mining versus underground mining, because of better machinery and a more effective mineral transport system. As early as 1971, Fluoruros S. A. started open cast extraction from the Valnegro pit in Pie de Potro.
From a mineralogical point of view, the paragenesis is similar to the rest of the mines of Caravia district, which it is to say: fluorite, barite, quartz, calcite, several sulfides and the very few crystallized specimens that have been preserved look like the ones collected in the neighboring mines, such as Valnegro, Jaimina and El Vallín, although perhaps their color is deeper and darker.
