Cornerstone and SolGold Define Additional Gold-Copper Soil Anomalies and Geological Targets at the Cascabel Project, Ecuador


MOUNT PEARL, NEWFOUNDLAND--(Marketwire - Dec. 20, 2012) - Cornerstone Capital Resources Inc. ("Cornerstone") (TSX VENTURE:CGP) (FRANKFURT:GWN) (BERLIN:GWN) (OTCBB:CTNXF) is pleased to provide an update on exploration activities at the Cascabel gold-copper porphyry project in Ecuador. The 5,000 hectare Cascabel Project is optioned to SolGold Plc (AIM code: SOLG), which is earning a 65% initial interest in the Project by spending $7.8 million over 4 years. SolGold is directing the exploration program and Cornerstone is implementing the program.

Exploration has progressed in 4 key areas -

  1. Further soil sampling continues to deliver very encouraging results
  2. Rock alteration mapping delivers very encouraging results
  3. Trench sampling confirms outcropping gold-copper mineralization
  4. Progress with components of the drill permitting process

Soil Sampling Survey

The regional-scale soil sampling program has progressed to cover the southern portions of the concession and to partially complete infill sampling of the northern area. The results have defined additional gold, copper and molybdenum anomalies, along with other supporting elements. The anomalies are clustered and cover a broad aerial extent as shown in Figures 2a, 2b and 2c of the following map link: http://cornerstoneresources.com/i/pdf/NR12-26Cascabel.pdf. The broad and coherent area of molybdenum anomalism in the south is considered most significant because of the association with strong and extensive alteration and supporting anomalism of other elements.

This is very encouraging and further supports and enhances the definition of the T1 target area, with coincident gold, copper and molybdenum. This target has been further strengthened by recent geological work (rock alteration mapping) outlined below.

Additional soil anomalies have been defined in other areas and these will be further investigated.

It is considered significant that extensive areas of gold, copper and molybdenum anomalism have been defined, and that these anomalous areas are open in most directions. The soil sampling program will need to be extended to define the limits of these anomalous areas.

Rock Alteration Mapping

A comprehensive 'rock alteration mapping' survey is being undertaken in conjunction with the soil sampling program. This survey identifies alteration minerals that may form in association with gold-copper porphyry systems. This exploration technique has been successfully applied elsewhere in the search for gold-copper porphyries, and in particular during the exploration phase of the Candrian prospect adjacent to the giant Tujuh Bukit porphyry deposit in Indonesia (Norris, 2009). Used in conjunction with other datasets it assists in locating the central parts of a mineralized system, and therefore provides vectors for drill planning.

Figure 3 (see map link) shows the 'spectral alteration map' and highlights areas of high temperature clay alteration coincident with the T1 geophysical target and areas of coincident gold-copper-molybdenum from soil sampling.

Trench Sampling

Rock saw trench channel sampling at Quebrada Moran has been expanded, and has been undertaken at Quebrada America and Tandayama. The results support the geological mapping and have defined some areas of anomalous copper and gold.

At Quebrada Tandayama 6 channels were sampled and delivered anomalous results of gold and copper (see Table 1 below). At Quebrada America 10 channels were sampled and delivered anomalous, but lower level assay results.

The results show that the area of Q. Tandayama and Q. America is a copper system with some supporting molybdenum, and weak gold, while results of sampling at the area of Q. Moran show that it is a gold-copper system. These differing geochemical signatures may also be related to erosional level. Drilling will ultimately test these concepts. The areas that have been channel sampled to date all lie outside of the main target (T1) at Cascabel. Future channel sampling will be conducted in the Quebrada Alpala area which lies within the principal target.

Drill Permitting Progress

The drill permitting process requires the concession holder to prepare water management plans, an environmental impact assessment (EIA) of the proposed drilling program, and to undertake a structured community consultation and endorsement program.

These activities are currently underway. The baseline studies for the EIA have commenced and a team from consulting firm Cardno-Entrix is on site and working with our community officer and the local communities. A draft EIA is expected by mid-January. Applications for water permits have been submitted to the Water Agency regional office (SENAGUA) for the sourcing of water from 5 potential sites to support the drilling program.

The anticipated first pass drilling program will be based on a 2,500 m program comprising man portable drilling rigs with very low environmental impact. Members of the local community have been taken to tour an active drilling program in southern Ecuador so that they may see first-hand the responsible way in which Cornerstone undertakes the exploration program.
