Quaterra Announces Two Properties Added To Goldcorp IFA

Drilling planned during fourth quarter 2011

VANCOUVER, B.C. — Quaterra Resources Inc. today announced that Goldcorp Inc. has elected to include two properties recently acquired by the Company under the terms of the Investment Framework Agreement (IFA) signed by the two companies early in 2010.

  • The El Calvo gold property covers 5,830 hectares located in the Altiplano region of the central Mexican state of San Luis Potosí. Multiple sediment-hosted gold targets have been identified by mapping and sampling over a four square kilometer area within an isolated block of sedimentary rocks rising about 150 meters above a flat plain of post-mineral cover. El Calvo sedimentary rocks include favorable lithologic units that host disseminated/stockwork gold mineralization in the Camino Rojo and Peñasquito gold deposits about 100 and 150 kilometers north, respectively. Drilling will begin at the San Jose target within the next month.
  • The Microondas gold-silver property consists of 9,057 hectares in Zacatecas State, Mexico, located within the Fresnillo silver trend that has produced several billion ounces of silver (see Quaterra news release dated July 4, 2011). The property is easily accessible by paved highways connecting to the city of Zacatecas, 120 kilometers to the southeast and to the town of Rio Grande, 15 kilometers to the northeast. The initial target is a 1.4 square kilometer area with widespread argillic alteration prospective for a high sulfidation type precious metal system. Quaterra’s surface sampling produced gold values from trace to 0.3 g/tonne and silver values from trace to 29 g/tonne, along with strongly anomalous arsenic, antimony and mercury. Quaterra plans to begin drilling in early November 2011. 

Progress on other prospects under the Goldcorp IFA is summarized below:

The Sierra Sabino project is in San Luis Potosí State, Mexico, about 120 kilometers south of Goldcorp’s Peñasquito mine. It is prospective for intrusive-related precious and base metal mineralization and is an Advanced Project as defined in the Goldcorp IFA. A total of 16 core holes have been drilled, primarily to evaluate a northwesterly-trending zone of anomalous gold geochemistry related to jasperoid and silicified limestone close to the western contact of a quartz porphyry stock. None of the 15 holes drilled within this zone intersected significant gold mineralization. One hole drilled into the contact of the quartz porphyry intrusive contains a 24 meter zone beginning at 388 meters of semi-massive to massive sulfide skarn averaging .0021 opt Au; 1.67 opt Ag; 0.33% Cu; 0.1% Pb; 0.23% Zn; 631 ppm W and 12 ppm Mo. Data evaluation is in progress to determine if additional work is warranted.

The Americas project is located in southern Durango State, close to its border with Zacatecas State and near the small village of Doce de Diciembre. Recent work has focused on the area in and around the Marimar vein, where core hole AMD-03 intersected 2.5 meters averaging 222 g/tonne silver, beginning at a downhole depth of 85.75 meters. As a deeper test, a second drill hole, AMD-11, was drilled in the same plane and below AMD-03. It intersected 1.29 meters of 83 g/tonne silver beginning at a downhole depth of 644 meters. Additional mapping and data review suggest that the most prospective search depth will be within the top 150 meters of the vein. A drilling program will begin in November to test the Marimar vein and a nearby vein swarm for near surface precious metal mineralization.

The Santo Domingo project is a copper-gold system hosted by both sedimentary rocks and a quartz porphyry intrusive. It is located about 120 kilometers west-northwest of Durango in Durango State. Seven widely spaced core holes have been drilled during 2011 to test a number of geochemical and geophysical anomalies. Although low-grade copper mineralization is widespread, no ore grade mineralization has been encountered. Two additional holes will be drilled this year to test structures with anomalous gold and silver geochemistry.

Other prospects. The Tecolotes mining concession consists of approximately 11,000 hectares and is located in the southeastern corner of the state of Durango. Geologic mapping, ground geophysical surveys and geochemical sampling have identified three targets on the property. The targets appear to be favorable for sediment-hosted gold-silver-base metal mineralization with potential for both open pit and underground type mining. It is expected that an initial drilling program will commence before the end of 2011 depending on drill availability.
