Silverton Metals Begins Exploration at Pluton Project

Silverton Metals has announced the beginning of exploration activities at the Pluton silver-zinc-lead project in Durango, Mexico.

Pluton is a 6,534-hectare property comprised of three contiguous exploration concessions, located along the eastern front of the Sierra Madre Oriental in northern Durango near Excellon Resources’ Platosa mine, one of the highest-grade silver producers in Mexico. The Platosa mine was graded at 506 g/t silver with a silver equivalent metal production of over one million ounces. Silverton’s Pluton project not only shares a similar geological environment to Platosa, but it also lies along strike from the past producing La Ojuela mine, historically one of the richest silver mines in Mexico and one of the first mines developed by Peñoles in the late 1800’s. Exploration targets at Pluton silver-lead-zinc and chimney carbonate replacement deposits, which may lie beneath the shallow alluvium and strongly altered clastic rocks that overlie the productive carbonate rocks.  

The company reports that the vein mineralization discovered is interpreted as leakage into the nonreactive shale-hornfels and is potentially connected to mineralized bodies in the carbonate rocks below. The high-grade target of silver-rich massive sulfides could lie at the contact of the limestone and the downward projection of the mineralized fractures seen in the hornfels.

“I am very pleased to start working on Pluton, the district is a major hydrothermal system with favorable lithologies, structure, alteration and widespread mineralization yet despite this remains relatively unexplored. Pluton is a district scale project targeting high-grade carbonate replacement type silver-zinc-lead deposits which are typically in the range of tens of millions of tons such as the Santa Eulalia mine in Chihuahua and represent robust exploration targets. The nearby Platosa mine is Mexico’s highest-grade silver mine with a silver equivalent grade of over 1,000g/t2”, said John Theobald, President & CEO of Silverton.
