Samples obtained from the reconnaissance sampling program represent chip-grab, chip-channel samples, as well continuous channel samples, either in outcrops or in jasperoid boulders and fragments within float. Most samples were obtained along lengths of 1.0 to 1.5 meters.
Next-step activities for the Petate project:
The Apartadero area (in the Petate West zone), and the Petate East areas are prime targets which require a trenching program in zones where the best precious metal anomalies occur, particularly along the northeastern margin of the Apartadero trend which hosts discontinuous outcrops of dikes. Channel sampling in the trenches should provide a better understanding of the length, width and grade of the mineralized zone(s).
Additional reconnaissance mapping and sampling is required west of the Apartadero area and in the southwestern sector of the district.
The Tecolotes area is believed to host several silicified reefs yet to be mapped and sampled in more detail.
The geology of the project is characterized by an anticlinorium/dome of the Mesozoic fold belt of the Sierra Madre Oriental. All mineral occurrences are hosted in the El Abra limestone of Lower Cretaceous age. A north-south trending remnant of the Upper Cretaceous clastics of the Mendez Formation is as yet un-eroded in a recumbent syncline between the Petate West and Petate East zones (see Figure 1). Scattered outliers of overlying andesites of the Tertiary Pachuca Group do not host alteration or hydro-thermalism, thus suggesting the hydrothermal system is more akin to the age of the Zimapan skarn/replacement type deposit (approx. 42 Ma), than the age of the Pachuca vein deposit (approx. 23 Ma).
In summary, the Apartadero zone highlights stronger gold values associated with Ag-Hg-Sb-As, whereas the Petate East areas are characterized by stronger silver values in association with Au-As-Ba-Fe-Mn. These preliminary results show strong geochemical signatures in the Apartadero and Petate East target areas, including multi-ppm values in gold at Apartadero, and greater than 50 ppm Ag at Petate East. Given the length of the silicified reefs, the Petate project area represents a robust system with excellent potential to host a preserved replacement type deposit at depth with elevated precious metals.
Fluid inclusion petrography indicates the fluids associated with deposition of crystalline quartz are relatively low temperature and salinity (130 degrees C to 230 degrees C; 0-3.0 wt.% NaCl equiv) indicating the surface exposures across the project area correspond to the upper portions of a preserved mineralized system at depth.
-- The geochemical signature of the western Petate zone (Au-Ag-Hg-Sb-As) is more indicative of low-sulfidation hydrothermalism, whereas-- The East Petate zone geochemistry (Ag-Au-Fe-Mn) is more indicative of intermediate-sulfidation hydrothermalism.
