La Frazada Silver Project


La Frazada Silver Project Mining Claims
The La Frazada project is 100% owned by First Majestic Silver Corp. as the project was acquired in 2012 as a result of the acquisition of Silvermex Resources. First Majestic holds the La Frazada project through one exploitation concession which totals 299 hectares. The Company is currently assessing La Frazada to determine if the property fits within the Company's portfolio.


The La Frazada Mine is located in the historic mining district of 'Real del Zopilote' within the state of Nayarit, Mexico. The property is approximately 300 km northwest of Guadalajara.

Local Geology

The La Frazada property lies along the southwest margin of the Sierra Madre Occidental. It is along the contact between the Upper and Lower Volcanic Series, which is an unconformity that hosts many of the significant precious metal deposits in the area.

Specifically, the geology consists of Tertiary age, Lower Volcanic andesites overlain by Upper Volcanic rhyolites, tuffs, breccias and ignimbrites. All of the volcanic rocks have been affected by intrusions of granodiorite, diorite and andesitic porphyry. The primary mineralized zones are La Jabalina and La Frazada Veins. These two parallel structures lie between 10 and 15 metres apart and vary in width from 3 to 15 metres.
