Corporate Shareholding - SIERRA INVEST PATAGONICA SRL - Based in Argentina

The company operates in Chubut Province (capital Rawson), located in the heart of Argentine Patagonia.

The city of Puerto Madryn represents one of the strengths of the entire region: overlooking the Atlantic Ocean and set in the Patagonian desert, it offers a unique landscape contrast. It is world-famous for its accessible and extraordinary biodiversity, especially in the nearby Valdés Peninsula, and is considered one of the best places for sighting the southern right whale, as well as penguins (at Punta Tombo), sea lions, elephant seals and orcas.

Mineral Resource: Patagonian Porphyry
 

Besides its tourist and naturalistic value, the desert area around Puerto Madryn boasts important mining and quarrying deposits of porphyry (porphyra). Porphyry is a volcanic rock prized since antiquity for its high strength and durability.

Global Context: The main global porphyry quarrying hubs are in northern Italy, Argentina and Mexico, with significant quarrying activities also in southeastern China, Iran and Bulgaria.

Local Geology and Extraction

In Argentina, the history of porphyry extraction and trade is inextricably linked to the industrial development of Puerto Madryn.

• Geological Framework: The deposits fall within the "Marifil Complex", a Meso-Jurassic volcanic unit outcropping mainly in the northeastern area of Chubut.

• Rock Characteristics: From a mineralogical and textural point of view, these are rhyolitic ignimbrites.

• Extraction Type: The quarries in the Puerto Madryn area allow the extraction of ignimbrites both in the form of slabs (with variable thicknesses and dimensions within the different quarry benches) and in massive blocks, making the raw material extremely versatile for the natural stone industry.
