Evaluation of ore deposits potential in the Andahuaylas – Yauri Batholith

INGEMMET through its Resources Mineral and Energy Direction – Metallogenic Program, signed an international cooperation agreement with the Korean Geological Survey (KIGAM) with the purpose of evaluating the ore deposits potential in the Andahuaylas – Yauri Batholith. This investigation includes metallogenetic interpretations using geochronological, isotopic, petromineralogy, structural studies, as well as geochemistry of rocks and sediments. The importance of this area has increased over the years, during which many exploration works were carried out and consequently, many mineral occurrences have been discovered. Considered now as a probable extension of some copper belts of Chile (Perelló et al., 2003); nearly 70% of the area has been granted as mining concessions to different mining companies. Initially, this was considered exclusively a Fe-rich zone, but later on more detailed studies came to the conclusion that it hosts a series of ore deposits related to Cu – Au – Mo porphyry systems. The international cooperation project lasted approximately 9 months, and included three field trips. During this period, mines, projects, prospects and potential areas free from mining claims were evaluated. The Andahuaylas - Batholith domain was divided into two study subzones, known as “A” and “B”. One of the main areas in the subzone “A” was Cotabambas, where a series of porphyry deposits are located and are known collectively as the Cotabamba cluster. In the surroundings of this cluster, the Colca area was recognized, which has some potential to host an ore deposit. The geologic features are very similar to those of the Cotabambas cluster and small outcrops of malachite along fractures can be observed. Several mineral occurrences were visited in zone B, such as: Angostura, Santa Rosa de Virundo, Yuringa, Atacancha, San Diego, Lahuahi, Jara Jara, Utupara and the surrounding areas of Las Bambas. Within this subzone, the Jalaoca area was recognized as an important potential area. This is located about 8 Km west from the Mollebamba city, very close to the inactive mines of San Diego and Lahuani. Polymetallic vein-type mineralization (quartz – molybdenite – hematite – chalcopyrite – bornite and galena) has been identified, as well as stockwork structures with piryte and chalcopyrite probable related to porphyry deposits. Another interesting area in the subzone “B” was Supamarca. This occurrence is located on the left side of the Abancay – Andahuaylas road. Copper suphide mineralization and hematite in thin laminates associated with siliciclastic rocks such as the sandstones of Muñani Formation (Upper Cretaceous – Paleocene) have been identified. These occurrences share some common features with such copper occurrences in red beds in the eastern sector of the Andahuaylas – Yauri Batholith. This document presents new geochemical interpretations based on geochemical analysis of rocks and stream sediments. Geochemical graphic representation of major and trace elements give us an idea about the type of magmatism developed in the area and its associated potential. Isovaloric maps of stream sediments confirm the potential that some areas. Interpretation of the data that polished and thin sections offer, confirm the type of rock and magmatism in the area of study. Finally, using the isotopic data collected from different studies it related the isotopic signatures with the expected tonnage for some porphyry deposits. In this investigation, samples were collected from the Cotabambas cluster for isotopic and geochronology studies. Those samples are being currently analyzed at KIGAM laboratories (Korea). This INGEMMET and KIGAM joint work tries to gather all the information related to the Andahuaylas – Yauri Batholith, and to update the existing geological data with the new data obtained from the field and office work, with the final purpose of providing exploration companies a new regional tool that will help them to better conduct their exploration campaigns

Labor absenteeism and its economic cost in a social enterprise of the northeast state of Antioquia, January 2017 to October 2018

RESUMEN: Objetivo: Caracterizar el ausentismo laboral de origen médico y no médico de una empresa social del estado del nordeste antioqueño en el periodo de enero de 2017 a octubre 31 de 2018. Metodología: Se realizó un estudio descriptivo, transversal, retrospectivo en el que se analizaron 285 registros de ausencias, identificando los grupos de diagnósticos de acuerdo con la clasificación de enfermedades CIE 10, las causas del ausentismo laboral de origen no medico como los permisos, el comparativo del ausentismo por sexo, número de días de ausencia, incapacidades médicas y el costo económico generado por cargos. Resultados y discusión: Se revisaron 76 historias laborales, 44 funcionarios se ausentaron, el 76% ausentismo no médico y el 24% de origen médico. El 97% de las incapacidades se debió a enfermedad general, el rango de edad de 50 a 54 años fue donde más se presentaron las ausencias de origen médico. El 25% de las causas son las enfermedades musculoesqueléticas, similar a lo reportado por otros investigadores. El 43,3% fueron permisos para citas médicas y un 22% para diligencias personales. Las incapacidades médicas correspondieron a enfermedad general. Las mujeres se ausentaron más del trabajo; el mes de agosto es donde se incrementaron las incapacidades médicas. Los cargos en los que se presentó mayor ausentismo fueron la enfermera profesional, odontólogo y médico general. El ausentismo laboral genera costos directos e indirectos en las empresas, se hace necesario implementar un programa de vigilancia de salud ocupacional de factores de riesgo al ausentismo laboral.ABSTRACT: Objective: To characterize the absenteeism of medical and non-medical origin of a social enterprise of the northeast Antioquia state in the period from January 2017 to October 31, 2018. Methodology: A descriptive, cross-sectional, retrospective study was carried out in which 285 records of absences were analyzed, identifying the diagnostic groups according to the classification of ICD 10 diseases, the causes of work absenteeism of non-medical origin such as permits, Comparison of absenteeism by sex, number of days of absence, medical disabilities and the economic cost generated by charges. Results and discussion: 76 labor histories were reviewed, 44 officials were absent, 76% were non-medical absentees and 24% were of medical origin. 97% of the disabilities were due to general illness, the age range of 50 to 54 years was where medical absences were most present. 25% of the causes are musculoskeletal diseases, similar to that reported by other researchers. 43.3% were permits for medical appointments and 22% for personal inquiries. Medical disabilities corresponded to general illness. Women were absent more from work; the month of August is where medical disabilities increased. The charges in which there was greater absenteeism were the professional nurse, dentist and general practitioner. Labor absenteeism generates direct and indirect costs in companies, it is necessary to implement a program of occupational health surveillance of risk factors to work absenteeism. Key words: Work absenteeism, disability, permit, diseases, costs

Copper in Peru: Present status and future challenge

The copper mineralization in Peru is intimately associated with porphyry Cu deposits and subdivides into three porphyry Cu belt as Paleocene, Eocene-Oligocene, and Miocene. Up to now, the total copper production from them reach 28 Mt Cu. The total copper production from the Paleocene Cu belt, including Toquepala, Cuajone, and Cerro Verde, accounts for approximately 57% of total copper production from Peru. But focusing mineral exploration on middle southern (Eocene-Oligocene) and northwestern part (Miocene) of Peru results in new discoveries, including La Granja, El Galeno, Las Bambas, Toromocho, and Rio Blanco, which have an estimated annual production more than 200,000 t Cu. In addition to them, thirteen Cu deposits are discovered from the Paleocene, Eocene-Oligocene, and Miocene Cu belts. Thus, Peru is supposed to produce Cu production from 2014 and increases annual production from 143 Mt Cu in 2012 to 490 Mt Cu in 2019. Due to new discoveries, it is expected that mineral exploration activities in Peru are likely to move from Paleocene Cu belt to Eocene-Oligocene and Miocene Cu belts

Gold in Peru: Present status and future challenge

Total reported gold resources in Peru is about 192 Moz. Gold production in Peru was 4.9 Moz in 2013, which was ranked first in Latin America and sixth in the world. Historic cumulative gold production in Peru is 118 Moz, and production from main gold belts including Miocene epithermal belt, Carboniferous-Permian orogenic gold belt and Upper Cretaceous intrusion-related gold belt corresponds to 84%. Most of production areas are located in Northern part of Peru, which corresponds to 63.5% of the total domestic production. Annual production onces in Yanacocha mine and Alto Chicama were 1 Moz and 0.606 Moz in 2013, which were ranked first and second in Peru, respectively. Gold production in Peru is expected to be 6.5 Moz in 2017. To accomplish the expected production, ongoing 14 projects should be developed to the production stage in three years
