Using the Discount Cash Flow Model in Preliminary Assessment for Gold Mine Projects

This study aims to the examination of the economic potential for the Abu Marawat Gold Project (AGP) in the Eastern Desert of Egypt and prediction the decision about go/not-to-go to invest in the deposit location. Discount Cash Flow (DCF) model used to calculate the Net Present Value (NPV) for the proposed gold mine project. NPV calculated by taking the risk and uncertainty produced from geological and technical factors into account. The actual production and cost data for Sukari Gold Mine (SGM) of Egypt used a benchmark for the theoretical calculation for production and cost data of AGP. From the valuation processes for AGP the NPV for the project predominantly positive, so, the project is acceptable to investment.

Effect of Cutoff Grade and Stripping Ratio on the Net Present Value for Hamama Gold Project, Eastern Desert, Egypt

This paper represents an attempt to examine the effects of Cutoff Grade (COG) and Stripping Ratio (SR) on the Net Present Value (NPV) for the proposed gold mine in Hamama area, hence to attain best operating condition corresponding to the optimum COG and SR in the proposed gold mine. Discount Cash Flow (DCF) model has been established to calculate NPV by taking the change in the COG and SR into account. This detects the effects of COG and SR on the NPV of this project. The actual production and cost data of Sukari Gold Mine (SGM) of Egypt have been taken as an indicator in creating DCF for the proposed gold mine where maximum NPV results proved the optimum COG and SR.

Fuzzy logic, parity theories and two currencies valuation for emerging markets with de discount cash flow model

The discount cash flow model must incorporate, in emerging economic systems, a conceptual framework for the inflation and valuation in two currencies treatment. The start point are the parity theories and Fisher effect, adding fuzzy logic for project uncertainty variables: interest rates, inflation, exchange rates and quantities, becoming one of its main contributions. The structure of the paper as follows: they are developed the parity theories and model´s equation at the fuzzy logic framework. Its functioning is illustrated with case of a firm located in an emerging and inflationary economy like Argentina, using spreadsheets. Finally, the results obtained showed the consistency with the parity theories, adding fuzzy logic for the uncertainty treatment, at the comprehensive framework of discounted cash flow model in two currencies.

Geographical proximity on the valuations of unlisted agrarian companies: Does distance from company to company and to strategic points matter?

This paper is a first attempt to examine the role played by the geography on agrarian firms’ valuations. The geography was evaluated through the physical proximity from agrarian companies to other companies and to some strategic points which ease their accessibility to external economic agents. To get our purpose, we developed an empirical application on a sample of non-listed agrarian Spanish companies located in the region of Murcia over the period 2010-2015. We applied Discount Cash Flow methodology for non-listed companies to get their valuations. With this information, we used spatial econometric techniques to analyse the spatial distribution of agrarian firms’ valuations and model the behavior of this variable. Our results supported the assertion that agrarian firms’ valuations are conditioned by the geography. We found that firms with similar valuations tend to be grouped together in the territory. In addition, we found significant effects on agrarian firms valuations derived from the geographical proximity among closer agrarian companies and from them to external agents and transport facilities.

Poly Real Estate Value Evaluation Research

This paper made valuation research on poly real estate by combining the actual situation of poly real estate and special factors affecting real estate industry assessment, using relative valuation method p/e ratio method and price-to-book ratio method, and discount cash flow method in absolute valuation method respectively. Three methods valuation results have little difference from the actual price, and are in line with the actual situation. By contrast, two methods valuation results are slightly lower than the actual price, which means that poly still has a certain rise space. From overall analysis, discount cash flow method is more rational comparing with valuation method.

Assessment of irrigation dam using real options and discounted cash flow approaches: a case study in Greece

This article extends the evaluation techniques of an irrigation dam in northern Greece, called “Petrenia”, by comparing the real options approach along with, a traditional one, the discount cash flow. By introducing first a Monte Carlo simulation, the various uncertainty factors can be simulated and alternative value options can be computed, feeding them later in the real options model. Results from the case study in Greece clearly demonstrate that the irrigation dam can be classified as a profitable investment, by applying traditional discount cash flow analysis, while by applying the real options approach the project cannot be classified as profitable. Taking into consideration the uncertainty factors, the real options approach reveals that the investment could be postponed and decision makers can keep the option of investing open. Sequentially, discount cash flow analysis accompanied by the real options approach facilitates decision making and improves the investment assessment analysis. In this particular project assessment, two uncertainty factors, variation in dam capacity and water price, restrict the profitability of the irrigation dam, according to the results of the real options approach.

Thermo-Economic Analysis of Combined Cycles

The paper presents a thermo-economic analysis of gas/steam combined cycle. The stated objective is achieved by optimizing thermo-economic parameters for simple combined cycle (large and medium range) and to apply this to economic model of these cycles. The economic parameters evaluated in the present study include discount cash flow rate of return (DCRR) and gross payout period (GPO), two terms commonly employed in engineering economic analysis. DCRR and GPO are calculated for various electric sale and fuel prices. It has been found that maximum value of DCRR and minimum value of GPO are found with large size plant.
