Quaterra In-Fill Drilling Confirms Continuity of High-Grade and Bulk Mineable Mineralization At Nieves
- QTA-84: 32 meters averaging 212 g/t silver (6.2 oz/ton) starting at a down hole depth of 72 meters, including a two-meter interval averaging 0.98 g/t gold and 2254 g/t silver (65.8 oz/ton). This mineralization is shallow, starting about 60 vertical meters below surface.
- QTA-89: 23 meters averaging 272 g/t silver (7.9 oz/ton) starting at a down hole depth of 141 meters, including 10.5 meters averaging 437 g/t silver (12.8 oz/ton). This intercept, together with hole QTA-87, suggests additional potential to the east and at depth.
- QTA-94: 42 meters averaging 127 g/t silver (3.7 oz/ton) starting at a down hole depth of 106 meters, including 2.1 meters averaging 548 g/t silver (16.0 oz/ton).
A 400-meter section of the Concordia-Gregorio Vein drilled on 50-meter centers during 2008 resulted in the delineation of an indicated and inferred silver resource completed by independent consultant Caracle Creek International Consulting Inc. (See press release of March 2, 2009).
The current program, with an increased drill density of approximately 25 meters between holes, aims to overcome difficulties constraining the initial resource model. Thirteen core holes, totaling 2902.70 meters, were completed in November and December 2009. Additional in-fill drilling to complete the 5,000-meter program is in progress with completion expected by late February. After receipt of all assays, a new resource model and resource estimate will be completed before undertaking additional work programs.
Detailed geologic mapping and veinlet sampling along the Concordia-Gregorio Vein and in the San Gregorio Hill area have identified multiple mineralized sheeted veinlet systems with the potential for relatively shallow silver mineralization. These data will be used to plan additional drill tests designed to discover new mineralization similar to the La Quinta style of stockwork veinlet mineralization.
Exploration maps illustrating all of these features are posted on the Quaterra website. A table of drill-hole results is attached to this news release and posted on the Company’s website. All holes were drilled at an azimuth/inclination of 340 degrees/-60 degrees. The approximate location of each drill hole at the mid-point of its intersection with the stockwork veinlet zone is shown in the long section. True thicknesses are about 80% of intercept widths reported.
Core samples were prepped and analyzed by ALS Chemex in Guadalajara, Mexico and Vancouver, B.C. respectively. Property-specific standards were routinely submitted with each batch of samples. Samples were initially run using a conventional 35-element ICP analysis with an aqua regia digestion process. A 30-gram fire assay with gravimetric finish for gold and silver was run on all samples. ICP results are reported for silver values up to 100g/t; fire assay results are reported for silver assays > 100g/t. Samples containing more than 1% lead, copper or zinc were analyzed using AA with aqua regia digestion.
