Ongoing 3-Dimensional Structural Analysis and Mineral Resource Evaluation on the Colibri, Ramard, and Leon Properties, Sonora, Mexico

Vancouver, January 22/CNW/ Colibri Resource Corporation has contracted Dr. Jonathan Nourse (B.Sc. Colorado School of Mines, 1983; PhD. Caltech, 1989) to carry out a detailed 3-dimensional analysis of the geology, structure, and mineral resources on three company properties in Sonora, Mexico. Nourse will integrate his ongoing geological mapping with the latest results from drilling, surface assays, and IP/Resistivity surveys. His focused work will guide Colibri in their planning of new drill targets within the structurally-controlled mineralized zones that exist on all three properties. The study areas include a promising gold property (named “Colibri”), an extensive silver-zinc-garnet scarn/porphyry property (“Ramard”), and a silver-molybdenum property (“Leon”). All three mineral concessions are centered within historical mining districts. Diamond core drilling is currently underway on the Colibri property, while Air-Trac percussion drilling is sampling shallow levels of the scarn at Ramard.

Dr. Nourse has been conducting geological field mapping in Sonora since 1985. He is coeditor of a recent Geological Society of America Special Paper on the Mojave-Sonora megashear, a major Jurassic transform fault system that appears to have facilitated the structural preparation for gold mineralization on the Colibri property as well as several nearby gold deposits of the Sonoran gold belt that include La Herradura, El Chanate, Noche Buena, and La Choya. In Nourse’s words: “I am excited about this opportunity to focus several months of my time on intriguing structural problems in Sonora. Normally, I have to squeeze my Mexican field work into one-week sessions during quarter breaks at Cal Poly Pomona, usually in December, March, and sometimes September. This project provides a timely mechanism to mesh my research experience on Sonora structure with the pressing economic interests of Colibri Resource Corporation.” Colibri Corporation is funding a sabbatical for Nourse, releasing him from Winter quarter, 2007 teaching duties with the Geological Sciences Department at California State Polytechnic University, Pomona.

Dr. Nourse has served on the Colibri Board of Directors as Vice President of Exploration since May 1, 2006. He has conducted preliminary studies of all three company properties during six trips to Sonora since January of 2005.
