The Cerro de Cobre project targets high grade copper in a brecciated limestone host, where existing prospects appear to be at the margin of a strong MMI soil anomaly that has not yet been drill tested.

Project Summary:

The Cerro de Cobre property hosts high grade copper and silver replacement-style mineralization within brecciated Paleozoic carbonate sediments.

Location and Mining History:

The property is 100% controlled by CMJ, and is covered by 283 hectares of contiguous mineral contracts. Cerro de Cobre, also known as Gachala, occurs in the Chivor-Gachala Mining District, Department of Cundinamarca, Colombia, and is located approximately three hours by car from Bogota. Although no copper production has been recorded in this region, a strong tradition of emerald production in ongoing.

Economic Geology:

The copper mineralization at Cerro de Cobre is structurally controlled, and is localized along a series of low angle, imbricate thrust slices. The low angle structural setting is related to the regional scale La Colonia thrust fault, and the property also occurs near the axial hinge line of the El Diamante anticline which may be an important regional control on mineralization. Copper mineralization consists entirely of chalcopyrite replacement and open space filling in silica flooded, brecciated carbonate sediments within the thrust faults.

Historic exploration data suggests the main Cerro de Cobre zone is up to 10 meters wide, and Colombian Mines sampling has shown up to 3.36% copper locally. Outcrop rock sampling at the property's Way Tunnel copper mine by CMJ geologists has returned a composite interval of 22.8 meters (10 meters true width) grading 3.16% copper and 15.3 g/t silver. Individual samples within this interval return values ranging from 0.24% to 8.89% copper and up to 29.1g/t silver. The Company's reconnaissance work has located several old tunnels and prospects, and identified apparent extensions of the copper mineralization along strike from the Way Tunnel. CMJ sampling 500 meters to the southwest along this projected structural trend at the Ladino Tunnel returned 5.2 meters with an average grade of 2.23% copper. Prospecting has also identified additional mineralized structures proximal to the main Cerro de Cobre zone.

Underground selective mining methods are well suited to the high grade mineralization and steep topography at Cerro de Cobre. Importantly, an underground mining method minimizes the environmental footprint and surface impact of a future operation in the area. The property is accessible via paved roads, and has access to water and hydroelectric power sources in the area.
