Location:

The Carol Project is located in southern Sonora State, 20 km north of the city of Alamos in the foothills of the Sierra Madre Occidental belt. The Carol property is approximately 5km North East of the Piedras Verdes Copper Mine, the 3rd largest mine in Mexico, 198 million tonnes @ 0.39% Cu, M&I (source Cobre del Mayo NI-43-101 Feb 12, 2010).

Deposit Model: 

Copper-silver-zinc-gold skarn.

Size: 

Six mining claims that cover 758.14 hectares (7.6 km² or 1873 acres)

Summary:

The Carol Project is a drill-ready exploration project with initial targets generated from multiple field seasons. Work completed to date consists of detailed geological mapping, soil geochemistry, rock chip sampling, and trenching.

Future exploration on the Carol Project will consist of ground geophysics and drilling of the most promising targets.

Geology:

The Carol property hosts two skarn zones: Balde South and Balde North. The Balde South measures approximately 1,100 metres long and 400 metres wide, while the Balde North, located 800 metres away, measures approximately 300 metres by 800 metres. Between the two is the La Escondida zone, which appears to be a mineralized structure that may be associated with the formation of the skarns. 

The oldest rocks within the property area are fine grained metasediments of Permian - Carboniferous age. These rocks have been intruded by early Tertiary granodiorite, and so the metasediments occur as roof pendants within the granodiorite. The metasediments have locally been altered to skarn or hornfels along the intrusive contact. Skarns within the property likely formed as a result of infiltration metasomatism involving magmatic hydrothermal fluids from the nearby granodiorite stock.

Each of the seventeen trenches revealed continuously mineralized intervals over widths between 4 and 48 metres. Of the 232 samples taken 185 were taken within skarn with each sample being two metres in length. Within the trenches there were many high grade sections. The highest copper assay received was 7.67 % and 38 samples returned greater than 1% copper. The highest zinc assay received was 15.30 % and 62 samples returned greater than 1% zinc. The highest gold assay received was 2.24 g/t (La Escondida) and 30 samples returned greater than 0.3 g/t gold.

In several locations deeper than expected overburden did not allow for the sampling of the underlying bedrock as the trenches were dug by hand, hence several of the zones remain open in at least one direction. This is significant in that there is the potential, with additional trenching, to show mineralization over much wider widths.

Averages from all sampling are shown in the table below.
