Santa Maria Project

Overview

High grade underground silver-gold mine located in the mining friendly jurisdiction of Chihuahua, Mexico.

43-101 PEA completed on September 15, 2018 by Mineral Resources Engineering.

Significant vein structures within the property provides future exploration and mining opportunities.

The mining and processing of mineralized material can start quickly due to existing infrastructure.

Robust vein system not fully explored, providing future exploration and mining opportunities.

The Santa Maria deposit type can be described as an epithermal quartz – calcite vein system.

Typically banded epithermal textures are observed in underground working and drill core.

Brecciated mineral textures filled by quartz and calcite are common. Low concentrations of galena and sphalerite and the presence of silver minerals indicate an elevated level of exposure within the epithermal system.

It is common for epithermal deposits to have higher-grade lineation trends internal to the structure’s plane often related to regional structures or preferential host lithologies. Modeling to date has defined two such shoots.

Past exploration programs have been planned in the context of mineralized structures, assuming the Santa Maria and Santa Maria Dos deposits are approximately planar and follow the general structural trends observed on surface and through out the underground workings. Successful exploration drilling down-dip of the workings supported the past assumption that the Mineralization structures follow oriented structural trends.

Blue Sky Exploration Potential

  1. High grade silver-gold property located in the mining friendly jurisdiction of Parrall, Chihuahua, Mexico.
  2. The Parral mining district is situated in the centre of the Mexican silver belt epithermal silver-gold vein districts. The belt has been recognized as a significant metallogenic province, which has reportedly produced more silver than any other equivalent area in the world.
  3. 43-101 PEA completed in September 15, 2018 by Mineral Resources Engineering.
  4. Significant vein structures within the property provides future exploration and mining opportunities.
