DENVER, COLORADO--(Marketwire - Nov. 14, 2012) - Bellhaven Copper & Gold Inc. (TSX VENTURE:BHV) ("Bellhaven" or the "Company") describes ongoing target generation work and upcoming drill testing of four distinct targets near the La Cantera and Middle Zone resources in Colombia. These efforts will include at least 5,000 meters of diamond drilling, and continued work on geophysical target modeling. In addition, the Company is set to conduct a ZTEM (airborne electro-magnetics) survey over the entire La Mina property.
Since so much of the La Cantera and Middle Zone deposits cropped out and exhibited obvious geochemical and geophysical anomalies, the next stage of exploration around the La Mina district was deferred for a time. The initial drilling focused on these known targets at surface. The team has now commenced the next round of targeting. This work includes investigations of historic mining in the area, large-scale soil sampling, as well as mapping and sampling over this large mineral system. The drilling is advancing into these areas where the latest geological interpretation has identified some strong targets with potential to grow the resources.

Patrick Highsmith, Bellhaven's CEO, commented on the program: "It is exciting to see these new targets emerge from the work of our technical team. We now have coincident soil and geophysical anomalies defined over an area of 3 kilometers by 1.5 kilometers, stretching well beyond the existing gold and copper resources. The patterns we see in the geophysics, sampling, and mapping are indicative of a very large mineral system, confirming our early assessments of the potential at the La Mina Project. We look forward to reporting the results as we systematically advance through these targets."
Discussion of Ongoing Target Generation Results and Drill Plan
The program has thus far succeeded in defining four drill-ready targets using a combination of methods. These are: (1) possible historic underground mine workings immediately west of Middle Zone; (2) geophysical and geological targets between the La Cantera and Middle Zone deposits; (3) an east-west linear target between La Cantera and the La Garrucha mineralized porphyry; and (4) a large geophysical and geochemical target at Cristalina, about 500 meters south of La Cantera. The geological team will conduct a drill program of at least 5,000 meters shared among these targets.
As part of ongoing geological work on the La Mina Project, geologists have been conducting mapping, sampling, and interviews of miners from the local community. While information is incomplete, a number of people identified an area of historical mining immediately west of the Middle Zone deposit. Soil and rock sampling in the area revealed silver, antimony, and gold anomalies indicative of possible epithermal veining. The historic mine workings were covered by minor landslide deposits, but geochemical anomalies identify a structural trend cutting the area. The Company will target at least 1 drill hole in the area to test for evidence of these veins.
The technical team is also conducting a rigorous 3D modeling exercise of all the available geophysical data around the La Cantera and Middle Zone deposits. The objective is to define the 3D structure of known and potential porphyry systems on the property. The work was contracted to the world-leading geophysical experts of Condor Consulting, located in Denver, Colorado. The geophysicists incorporated the entire database in their study, including: two aeromagnetic surveys, ground magnetics, IP, radiometrics, and down-hole magnetic susceptibility. These data are integrated with geology, structural measurements, and resource drilling to aid in a full interpretation. Though the work by Condor Consulting is ongoing, the Company has received encouraging initial results. Results to date suggest that the La Cantera resource and the La Garrucha porphyry have a magnetic connection at some depth (see Figures 1 and 2 for a plan view and a 3D image viewed from the south). Also of interest are several distinct chargeability and resistivity features between the La Cantera and Middle Zone resources. These complement prior magnetic interpretations suggesting possible links between the two deposits.
New field measurements by Bellhaven geologists show evidence for a number of geological structures to the east and south of La Cantera. An interpreted NE trending regional lineament has been confirmed by numerous faults observed in the Cristalina area, approximately 500m south of La Cantera. These structures conform to patterns seen in local drainages that align with the La Garrucha porphyry. Another important discovery is evidence of an EW trending connection between La Cantera and La Garrucha. Fault and vein traces in rock exposures, along with drainage and topographical patterns, point to a possible set of faults that lie parallel to the observed magnetic response noted above. These fault and vein patterns may be significant as they could define the controls for emplacement of porphyry, breccia, and vein deposits.
Approximately 500 soil samples now cover the area surrounding La Cantera, Middle Zone, and La Garrucha, all the way to the southern property boundary. The area between La Cantera, Middle Zone, and La Garrucha is characterized by high arsenic and zinc in soils (100+ ppm As, 200+ ppm Zn - see Figures 3 and 4). Anomalous As and Zn are known to occur as halos to mineralized porphyries. There are also significant gold anomalies (50+ ppb Au - see Figure 5) associated with the faults to the east of La Cantera and Middle Zone. These geochemical anomalies echo the significance of the area between La Cantera and Garrucha as a drill target.
Large and robust arsenic and zinc anomalies also exist in the Cristalina area, at least as intense as in the area described above. The Cristalina anomaly lies directly in the north-south corridor defined by La Cantera, Middle Zone, and El Limon, at approximately regular intervals, 400 to 500 meters. The geochemical response associated with this corridor suggests the presence of a porphyry system, though none has been mapped, and no anomalous gold is noted in sampling. A positive magnetic anomaly exists on the SE shoulder of this area. The current interpretation is that the target is a mineralized porphyry buried by volcanic rocks, altering the geochemical and geophysical responses.
Drilling has already commenced in these areas and is expected to run through to January. Any other drilling program that may initiate during this time will be run in parallel by contracting additional drill rigs.
Discussion of ZTEM Survey
Bellhaven has contracted Geotech Ltd., a Canadian geophysical survey company, to run a helicopter-borne ZTEM survey over the entire La Mina property (1,800 Ha). The EM and magnetic survey will cover approximately 132 line kilometers and use flight lines at 200 meter spacing. The survey is expected to define the mineralization and alteration associated with large mineral systems to considerable depth, as well as enhance understanding of large structures. In addition, the information will supplement the current understanding of geophysical properties around the known mineralized porphyries. The survey is expected to be completed in the next month.
Drilling at the El Limon Target
The Company has just completed additional drilling at the El Limon porphyry target, located approximately 300m north of the Middle Zone resource. Five new drill holes tested the western and southern portions of the geochemical and geophysical anomalies. The completed results from this latest drilling are expected before the end of November.
