3. Cordilleran magmatism in northwestern Mexico. The Cordilleran magmatism in northwestern Mexico began in the Permian during the Pangea break-up, according to U-Pb zircon dates on plutonic rocks, with ages between ~275 and ~258 Ma (Arvizu et al., 2009).Apparently, these rocks are part of a magmatic arc that extends …
Silver ore refers to natural deposits of silver-containing minerals that are mined and processed to extract silver metal.

The property is aligned with a 1,500km-long belt, rich in porphyry copper deposits, that runs from the south-western US to Guerrero State in Mexico. Reserves The North Zone is estimated to contain an indicated resource of 561 million tonnes (t), grading 0.33% copper, 0.008% molybdenum, 0.027g/t gold, and 2.1g/t silver as of October 2023.
For geochemical analysis, fresh rock samples were ground into powder in an agate ball mill through a ∼200 µm mesh. For major element determination, the samples were heated in two steps in separate ovens at 105 °C and 1000 °C, respectively, to measure loss on ignition (LOI). ... The ore-related porphyry shows Sr, Nd, Hf, and O …
The mineralisation at Santo Tomas is closely associated with intrusive rocks formed during the Laramide orogeny. The property is aligned with a 1,500km-long belt, rich in porphyry copper deposits, that …
The Suaqui Verde porphyry copper deposit is a small ore body of about 20 million tons of oxide ore grading 0.29% copper, located ~ 8 km E-NE of the town of Suaqui Grande in east-central Sonora, northwestern Mexico.The largest and better-known deposits occur in northern Sonora, whereas those from central and southern Sonora are smaller …
The oldest porphyry copper deposits (~77-74 Ma), which are coeval with the El Espíritu and Tresoro gold deposits, are distributed along a strip of land between the north coast of Sonora and the ...
Although porphyry Mo deposits are often volumetrically smaller than porphyry Cu systems, they are still a significant source of Mo owing to higher ore grades. Understanding the timing of mineralization within a magmatic region is important for making accurate regional ore predictions. High-silica granite-related porphyry Mo deposits
Porphyry copper deposits are best developed in association with the Laramide intrusive centers of northern Mexico and the mid-Tertiary intrusions in southern Mexico.
