Size: 299 hectares
Location: Nayarit, Mexico
Target: Silver Zin Lead (Epithermal Veins)
Development Stage: Resource Definition
Location and Access: The La Frazada Project is located in the Mexican state of Nayarit. Specifically, the Project is located within the central portion of the Mexican state of Nayarit, approximately 55 km northwest of Tepic, the capital of the state of Nayarit and 300 km to the northwest of the city of Guadalajara, the second largest city in Central Mexico. The Project is situated in the El Zopilote mining district within the Region de Ruiz mining area.
Summary: La Frazada was mined in the late 1890’s until about 1910 when the Mexican revolution effectively stopped all activity. Two parallel quartz veins with galena and sphalerite have been traced for over 1800m along strike and host mineralization in three known mineralized shoots. These resources were near surface and within the existing mine workings that are accessible today.
Geology: The La Frazada property lies along the contact between the Upper and Lower Volcanic series on the western edge of the Sierra Madre Occidental geological province. Specifically, the regional and property geology consists of volcanic rocks of Tertiary age, which include andesites of the Lower unit and lava flows, ignimbrites, tuffs and breccias of rhyolite and dacite composition of the Upper unit. All the rock sequences are affected by stocks of granodiorite, diorite and andesite porphyry. The contact between the Upper and Lower Volcanic series has been and continues to be highly prospective for precious metal mineralization, as a majority of the other known gold and silver mines and prospects in the belt occur close to, or just below, the contact interval.
The La Frazada Project consists of two parallel quart-veins and breccias which outcrop intermittently along a 3 km strike length within the property boundaries. Silver, zinc and lead mineralization appears associated with the quartz veins and a breccia at the footwall and hangingwall of the La Frazada and La Jabalina veins. Within the property, there are a series of underground workings which are presently accessible over a strike length of 3,000 m.
Exploration Upside: The down dip and along strike extent of the historically worked veins is not fully understood and further exploration has potential to lead expansion of existing resources. Based on the resource estimation previously completed by channel sampling significant tonnage and grade improvements can likely rapidly be made by modern drilling methods and more robust resource confidence.
Additionally preliminary samples from the host rock within altered zones returned low silver values that are associated with a stockwork and veinlet zones. This may be part of an extension structural process along the main vein system and may represent potential low grade bulk tonnage resource potential.
