Mineralización de las zonas de Colquipucro y Ayawilka, Proyecto Colquipucro, San Pedro de Pillao-Pasco

Abstract

The foregoing treatise serves as Thesis to obtain the professional degree of Geologist Engineer of the Universidad Nacional de Ingeniería (National University of Engineering), Faculty of Geological, Mining and Metallurgical Engineering, and Professional School of Geological Engineering. It was performed the study of mineralization in the areas of Colquipucro and Ayawilka, property of the Canadian explorer junior company TINKA RESOURCES S.A.C., located at the community of Colquipucro in the region of Pasco. These areas have been explored by many companies during the years, such as Buenaventura, and Sierra Minerals; Tinka Resources obtained the concession in 2007. Inside the lithological units located in the project area, it has been recognized Excelsior Group, Mitu Group, Pucará Group, and Goyllarisquizga Group. The exploration areas Ayawilka and Colquipucro have polymetallic mineralization of Cu, Pb, Zn, and Ag. The mineralogy presented in the areas corresponds to chalcopyrite, galena, sphalerite, among the minerals with economic value and others related to them; highlighting the presence of pyrrhotite. Its mining resources are in the order of 13.3 million of TM with 5.8 million of ounces of Ag which makes this area a mining project of exploratory interest. (The resource calculation must be indicated through the respective NI 43101 or JORC). According to the studies performed until now in the areas of Colquipucro and Ayawilka, and in the basis of the interpretation of mineralization characteristics of the deposit, the Colquipucro project could be related to the model type polymetallic stratabound of Pb-Zn-Cu-Mo hosted in sedimentary rocks type limestone of Pucará Group of the lower Jurassic. With this new interpretation proposal, it is expected to also contribute to improve the knowledge and economical expectation of the project for further mining operations.
