The Argentine company "Sierra Invest Patagonica S.r.l." has its registered office in Puerto Madryn, (Argentine Republic), in the Province of Chubut, legal domicile: Mitre 150, Piso 1, of. 3, and CUIT number: 30-65179790-6. The Province of Chubut with capital Rawson is one of the provinces of Argentina, located in the Patagonia region. Puerto Madryn is considered one of the most beautiful destinations in Patagonia for a rare combination: spectacular nature, unique animals, and wild but accessible landscapes. Puerto Madryn is one of the best places in the world to see the southern right whale in the Valdés Peninsula, as well as penguins (Punta Tombo), sea lions, elephant seals, and orcas. Puerto Madryn is also famous for its unique contrast between the Patagonian desert and the Atlantic Ocean. In the Patagonian desert there are also deposits/quarries of "porphyra" stone (= porphyry), which is a very resistant volcanic rock, used since ancient times. The main world production deposits are located in northern Italy, Argentina and Mexico. Currently extraction also takes place in southeastern China, Iran and Bulgaria. In Argentina, the area of economic interest is located within what in Argentine regional geology is known as the Meso-Jurassic volcanic unit: the "Marifil Complex", composed of rocks called rhyolitic ignimbrites due to their texture and mineralogy. These rocks are found in extensive outcrops, located mainly in the northeastern region of the Province of Chubut. The history of extraction and commercialization of porphyry in Argentina is directly linked to the development of the sector in the city of Puerto Madryn. The "porphyry area" of Puerto Madryn includes quarries that allow the extraction of ignimbrites in slabs. The dimensions of these slabs vary from site to site or quarry to quarry, and often both horizontally and vertically within the same site. Ignimbrites can also be massive, which makes them suitable for block extraction.
