    Compañía Minera Malú S. A.: un caso de evaluación de inversiones
    (Universidad ESAN. ESAN Ediciones, 2002-06-30) Mendiola Cabrera, Alfredo; Villanes Vergara, Liz
    This study addresses the case of a mining company that needs to evaluate the feasibility of a new attractive prospect in the Callejón de Huaylas, department of Ancash, for having estimated gold reserves of 1.4 million ounces. Attending to this objective, it sets out in detail the set of variables to be considered for the evaluation: exploration period, detail engineering need, estimation of the ore grade and exploitation period, investment requirements, operation, and administration costs, financing needs, and taxes pressure. With these data and an intermediate assumption about the price of gold, it is established that the project would be viable with an investment of 40% of own resources and 60% of resources of third parties with an interest rate of 9%. A fall in the price of gold would force an increase in the proportion of own resources.

    Coppermine: riesgos de la no concentración
    (Universidad ESAN. ESAN Ediciones, 2005-12-30) Jáuregui, Kety; Centeno, Adolfo; Solano, David
    Major greenfield mining projects are usually surrounded by conflict between the mining company and neighboring communities caused as much by the operator’s mistakes as by anti-mining coalitions and other organized groups rallied around sustainable development issues. For four years while preparation work was underway the mining company put into practice several strategies aimed at addressing claims, including participatory workshops all the way to hiring anexpatriate professional expert charged with addressing environmental issues. A few months before the beginning of mine operations however tension peaked. A multi-sector technical commission was set up including government, residents and company representatives. The technical committee has already issued its report on the issue, including recommendations to keep a watchful eye on the company’s operations. In view of such developments, Coppermine must reframe its policies and strategies.

    Toxicología ambiental en minería: herramientas para la evaluación del impacto
    (Universidad ESAN. ESAN Ediciones, 2003-12-30) Zegarra Macchiavello, Darío; Frías Martinelli, Óscar
    The growing interest in the effects that mining causes on the environment has given rise to new forms of prevention and control in this industry. The start-up of a mining operation can be understood as an alteration of an ecosystem in equilibrium it is already part of a system seeking equilibrium. But how much has the balance been broken and for how long? How to quantify the effect on biota inventories of the affected area? How to consider the bioaccumulation of xenobiotics in the habitat? How to include so many variables their relationships and their temporal evolution? The analysis through the time of these alterations or redefinitions of the variables present in the environment must be considered for a study of the impact on the environment. This paper presents criteria and tools for the analysis of the effects that a mining or industrial operation causes in its surrounding environment. The Probabilistic Risk Assessment (or Monte Carlo Simulation) and the Modelling of Dynamic Systems are analysed tools whose common base is the simulation of models as an approach for the development of summary representations of reality. In order to show the practicality relevance and applicability of these approaches a case study of each of them is reviewed.

    Cía. minera Milpo S.A.A.: valorización de una empresa minera
    (Universidad ESAN. ESAN Ediciones, 2007-06-30) Mendiola Cabrera, Alfredo
    Bailey Investments Inc. (BII) was restructuring their investment portfolio and examining the possibility of extending their exposure towards the Peruvian mining industry. Specifi cally, they were interested in investing in the Milpo Mining Company, about which they had very good references. For this reason, they asked MC Peru, who is one of their primary foreign customers, to create a report about the convenience for realizing this investment. They expected a comparison between the market price and the value of ordinary Milpo stock. Analyst Ernesto Valdez, who was in charge of this work, knew that he would only have a short time (three days) to do so, meaning that there would not be any time to converse with Milpo representatives, and his analysis would have to focus on public information available through the Internet.
