The Orani - Guzzurra - Sos Enattos area is located in central Sardinia and is composed of two distinct zones: one to the northeast of the city of Nuoro (Guzzurra - Sos Enattos) and the other to the southwest of Nuoro (Orani). The Orani area covers an area of 130 square kilometers, equivalent to 3.5% of the total surface of the Geomineral Park of Sardinia. Its geomineralogical importance lies in the presence of a significant talc-steatite deposit, a recently developed feldspar deposit, and numerous marble and granite quarries.

The region is partly mountainous and rugged, and partly made up of gentle and moderate hills. Its morphological structure shows a clear connection to the lithological characteristics of the outcropping formations. The highest altitude is represented by Mount Gonare, which consists of two cone-shaped peaks with elevations of 1,083 meters (Mount Gonare) and 1,045 meters (Mount Gonareddu). On the highest peak, a fascinating sanctuary was built. Other elevations rarely exceed 800 meters.

The entire area was known as early as the Late Neolithic for the presence of steatite, which was crafted into high-value and ornamental objects and statuettes of the Mother Goddess. Industrial-scale talc extraction began in 1917 as quarry material and, from 1927 onward, as a first-category material, although this raw material was already known since the mid-19th century.

The archaeological significance of the Orani area is marked by the presence of the Nurdòle Nuragic temple, located atop a hill. This monument, built in an inland area of Nuoro at a crossroads of penetration routes from the western and eastern coasts, features complex architecture and has yielded a significant quantity of artifacts.

The Guzzurra-Sos Enattos zone is situated in the northern Barbagia region, in central-eastern Sardinia. It covers an area of 133 square kilometers, also equivalent to 3.5% of the total surface of the Geomineral Park. The mining interest in this area is due to the presence of metal deposits of lead, zinc, copper, and silver, remnants of an extraction activity now completely ceased.

The main morphological features are typical of hilly areas, with relatively gentle forms, small hills barely exceeding 400 meters in altitude, and weakly defined valleys oriented along the area's main tectonic directions.

The landscape around the mine is characterized by the proximity of Mount Albo, a 30-kilometer-long limestone bastion, offering views over much of the Baronie and northern Barbagia regions, the eastern coastal landscape, Mount Senes, Mount Tuttavista, the island of Tavolara, the Supramonte, and the Marghine-Goceano and Gennargentu mountain ranges.

The geology of the area includes Paleozoic crystalline basement rocks (metamorphites intruded by Hercynian granites and a complex network of dikes) overlain in the eastern sectors by Mesozoic limestones and dolomites from Mount Albo in Siniscola.

The Sos Enattos deposit, the area's main mining site, has been known and exploited since ancient times. Some galleries identified in the past have been dated to the Roman era, while certain wells date back to the 11th century. The extraction of lead and zinc ores reflects a deep-rooted mining tradition. Although at its peak the mining activity employed hundreds of workers, it began facing a severe crisis in the 1960s, eventually leading to the progressive closure of the mines over the years.
