About the Corporation

Through its subsidiaries, Oremex Gold holds gold properties which include the San Lucas, Santa Catarina, Maco and Navidad properties located in Mexico, all of which are considered by Oremex Gold to be promising, early-stage mineral properties. At this stage, preliminary exploration and development work has been conducted on these properties, however there can be no assurances that any significant mineralization will be discovered on any of these properties.

San Lucas is the material property of Oremex Gold, and is the subject of a technical report filed on National Instrument Form 43-101F1. The San Lucas property is located 86 kilometres north of the city of Durango and accessed via paved highway. The property consists of seven mineral concessions covering approximately 1,235 hectares. San Lucas consists of a series of northeast trending gold and silver mineralized shear zones in volcanic and sedimentary rocks. Oremex Gold has designed a drilling program based on field sampling and mapping. Field work has been focused to define drill targets to test the gold mineralization present in a silicified dacite dike, which outcrops extensively on the concessions. A total of 220 samples have been collected along the silicified dacite dike, which also has cross cutting mineralized dikes, significantly adding to tonnage potential. The dike has three more intensely mineralized segments; the 330m long North zone reports silver grades to 1,856 g/t and gold grades to 1.06 g/t, the 800m long Central Zone reports gold grades to 1.68 g/t and the 180m long South Zone reports gold grades to 0.82 g/t. The mapped strike length of the silicified dacite dike is 2.0 km. Access rights to the San Lucas property for a period of 30 years, renewable at the holder's option for another 30 years, have been secured. The work report was completed under the supervision of William Feyerabend, a Registered Geologist and a Qualified Person as defined in National Instrument 43-101.
