Batero Gold Corp. (TSX VENTURE:BAT) today announced its most significant drill results to date at the company's 100-per-cent-owned Batero-Quinchia project in Risaralda Department, Colombia.
Significant highlights include:
- Drill Hole 8: 591.50 metres grading 0.72 g/t gold and 0.13% copper, including 519.70 metres at 0.80 g/t gold and 0.14% copper and 178.20 metres grading 1.0 g/t gold and 0.15% copper
- Drill Hole 5: 398.85m grading 0.46 g/t gold and 0.09% copper; including 149.70 metres at 0.59 g/t gold and 0.10% copper
"These drill results confirm our strategic approach to step-out drilling and strong belief that La Cumbre mineralization extends at depth," said Brandon Rook, President and CEO, adding, "Drill hole number 8 is the most significant intercept to date at our Quinchia project. We look forward to further expanding on these positive results."
Batero's fully funded drill program consists of 4 drill rigs operating 24/7. The company's goal is to define the mineralized extent of porphyry bodies found in 2006, and to test newly discovered target areas. Currently two drill rigs are being used to delineate and further explore the company's La Cumbre porphyry, where five historic drill holes yielded and confirmed the porphyry body. The company is reporting on results from drill hole's 3-8 at La Cumbre porphyry. A total of 11 holes have been drilled at La Cumbre by Batero.
Batero is using a third drill rig at its QAP-DDH-014 La Lenguita target – a new exploration target area discovered by Batero. La Lenguita is situated 500m northeast of the La Cumbre target area and is considered a top priority. Initial visual observation from the current drill hole indicates gold mineralization present with the potential that La Lenguita will be considered a significant new discovery. Results will be released once received, analyzed and verified.
A fourth drill is approaching the completion of its first hole at Batero's other high priority and new exploration target at Matecana, located 340 metres lower in elevation and one kilometre southeast of the La Cumbre porphyry.
Batero commenced its phase 1 – 16,000-metre – drill program in late October 2010. Due to initial positive results, the company will bring a fifth drill rig to the project which is expected to be operational by March 2011. And more significantly, the company anticipates a total of eight drill rigs to be in operation over the coming months.
As planned, Batero Gold Corp's drilling program is beginning to define the extents of the company's La Cumbre porphyry: drill holes QAP-DDH-004 and 006 have been useful in defining the eastern extents of the porphyry body, however QAP-DDH-006 intersected at the bottom of the hole what is interpreted to be a major fault structure (La Cumbre fault) warranting further investigation. La Cumbre porphyry remains open to the southeast and further drilling is planned to define these limits. Drill hole QAP-DDH-008 intersected significant hydrothermal breccia and significant mineralization. Along the NW-SE trending fault structure drill hole QAP-DDH-005 intersected what is thought to be part of the same mineralized hydrothermal breccia system intersected by QAP-DDH-008. These intersections are presently considered significant to the overall area and warrant further investigation.
Additional target areas are planned to be drilled in the near future.
This hole was collared at 420748E, 585249, at 1858m elevation, and was drilled at an orientation of 110/-65 for a total depth of 584.75 metres. This hole tested the south western extents of La Cumbre porphyry and was drilled towards historic drill hole DQ-DDH-018, which intersected 448.0 metres of 0.5g/t Au and 0.11% Cu. Predominantly, the hole drilled through porphyritic medium grained quartz diorite followed by approximately 26.0 metres of magmatic breccia before ending the hole. Mineralization is composed mostly of pyrite and magnetite stockwork veining with minor amounts of disseminated chalcopyrite, and sphalerite. Alteration is mainly biotitic and chloritic throughout, with lesser silicification.

This hole tested the south eastern extents of La Cumbre porphyry. Predominantly, the hole drilled through fault breccia in the top portions of the hole followed by magmatic breccia and porphyritic medium grained quartz diorite. The hole was shut down after cutting a 49.2 metre fault zone. Mineralization is composed mostly of disseminated and stockwork veining with dominantly pyrite with minor amounts of magnetite, chalcopyrite, bornite, and sphalerite. Alteration is mainly silicification at the top and bottom of the hole biotitic and chloritic alteration throughout the middle regions of the hole.
This hole was collared at 420748E, 585249N, at 1858m elevation, and was drilled at an orientation of 010/-60 for a total depth of 503.3 metres. This hole was drilled north to test the La Cumbre fault structure, which trends north west/ south east, and drilled towards the historical drill hole DQ-DDH-007, which intersected 265.3 metres of 0.49 g/t Au and 0.09% Cu and ended in mineralization. The hole drilled through hydrothermal breccia followed by intercalated porphyritic fine and medium grained quartz diorite, and completed the hole in mineralized hydrothermal breccia. Mineralization is composed mostly of disseminated and stockwork veining with dominantly pyrite with minor amounts of magnetite, and trace amounts of chalcopyrite and molybdenite. Alteration is mainly chloritic and biotitic at the top of the hole with a silicification dominant at the bottom of the hole.

Sample preparation, assays and quality assurance/quality control
Core is collected and initially logged at Batero Gold's drilling camp at the project area. The core is then securely shipped in core boxes to Batero's core processing facility in Pereira, Colombia. Here the core is logged in detail, cut and sampled, and all QC samples are introduced before the samples are shipped to ALS Chemex's sample preparation facility in Bogota, Colombia. Prepared samples are then shipped by ALS to their analytical facility in Lima, Peru for analyses.
Gold is fire assayed using a 50.0 gram aliquot sample using an Atomic Absorption finish (AA) and multi-element analysis is by Four Acid Digestion using and Induced Coupled Plasma (ICP) finish.
The Company's QA/QC program includes the regular insertion of blanks, multiple certified assay standards and duplicate samples into the sample shipments. These QC samples are inserted in every assay batch, which is composed of 25 samples. Regular monitoring of these QC samples is a critical part of Batero Gold Corps QA/QC protocols.
