Rosita District -- 100% Owned CXB


The 214 km2 Rosita District is host to a series of advanced targets including the Santa Maria, high grade gold-silver low sulphidation epithermal vein system. Other advanced Targets include Minnesota, Terciopelo, and others previously within the B2Gold Joint Venture.

The Santa Maria Project consists of a well-defined low sulphidation epithermal mineralization. Previous work by Calibre includes 16.3 line kilometres of soil sampling (812 samples), 55 rock samples as well as geological mapping over 9 km2. Low Sulphidation Epithermal vein mineralization is confirmed over 800 metres of strike length, and inferred over a total strike length of three kilometres. Rock sample results include; 64.1 g/t Au, 109 g/t Ag, 0.513% Cu, and 3.75% Pb,. Soil results define a 1000m x 50-100m Au-Pb-Zn ± Cu soil anomaly with results to 666 ppb Au, 1190 ppm Pb, 1050 ppm Zn and 889 ppm Cu.

The central portion of the Santa Maria Project area has been subjected to intermittent artisanal mining activity along a strike length of 800m. Exposures are largely limited to shallow shafts and pits which have been excavated by artisanal groups; rare float material is located in some areas. Sampling by Calibre has consistently returned anomalous gold and silver with highlighted results including;

The 100% owned Rosita District also hosts the Minnesota Gold Project. 2014 reconnaissance diamond drilling program at the Minnesota gold project consisted of seven widely spaced drill holes totaling 992 metres which tested three areas along the 3.5 km by 1.0 km trend of the defined by a strong auger and gold-in soil anomaly and surface rock sampling. Drilling results include: 31.35 metres grading 0.63 g/t Au including 12.40 metres grading 1.07 g/t Au and 47.0 metres grading 0.63 g/t Au including 4.50 metres grading 3.43 g/t Au.

Additional Targets within the 100% owned Rosita District include Terciopelo, Fruta de Pan, and others.
