El Habal

El Habal Summary

The El Habal precious metals project comprises 4,000 hectares and is located 75 km east of the modern coastal port of Mazatlán, and 10 km on a paved road from the historical mining town of Rosario, Sinaloa, Mexico.

El Habal’s mining concessions cover a 6 km long by 1 km wide trend, containing a series of historical shallow and small-scale underground artisanal mining sites, all resembling the Rosario Mine’s geology.

El Habal hosts excellent infrastructure for future mine development.

Regional Geology

The El Habal project lies on the southern edge of a major geological structure, “Panuco Graben”, highly analogous to the Rosario mine, which occurs on the edge of a similar geological structure nearby, Rosario Graben. Both El Habal and the Rosario mine are located in a region where two major NW and NE oriented trends intersect. GR Silver Mining considers this an ideal setting of geological structures, hosting highly prospective exploration targets on the western edge of the Sierra Madre Occidental, one of the most prolific geological environments for discovery of world-class deposits.

Recent exploration results returned gold mineralization outcropping along a series of low elevation rolling hills, represented by a prevalent stock work system in the major NW-SE structures hosted by oxidized Upper Tertiary Volcanic (Rhyolites and volcanic flows) and Lower Tertiary Volcanic (andesites). Sampling results from this exploration program also identified hydrothermal breccias and localized epithermal veins, resembling typical low sulphidation textures and mineralogy.

Exploration Status

In late 2017, GR Silver Mining completed a successful surface channel sampling and trenching program. The study revealed wide oxidized mineralized zones over a 2 km strike length, not only on historical mine sites, but also on the host rocks, including 4 new prospects: “La Reina”, “El Arenal”, “Santos” and “Octavio”.

Mapping along the 6 km long by 1 km wide geological trend together with a ground geophysical program generated additional targets for an additional drilling program.

The integration of the historical (non 43-101 compliant) drill data, combined with recent exploration results led to a drilling program by GR Silver Mining in 2018, aiming to define resources for both an open pit amenable project as well as underground potential.

Recent exploration concentrated in a 1.5 km long portion of the trend along the mineralized zone.  GR Silver Mining is focused on defining new mineralized zones, by way of continuing surface trenching, underground mapping and channel sampling, a ground geophysical survey (CSAMT) and a 4,000 metre drill program (completed in Q2 2018). The existing mineralized zone shows potential to expand along the 6 km trend.
