This paper motivates the problem of frequent subgraph mining on single uncertain graphs, and investigates two different - probabilistic and expected - semantics in terms of support definitions. First, we present an enumeration-evaluation algorithm to solve the problem under probabilistic semantics. By showing the support computation under probabilistic semantics is #P-complete,
Copper mining in Mongolia is a major industry and source of income for the country. There are only two companies that produce copper concentrate, Erdenet Mining Corporation, a Mongolian-Russian joint venture, and the Oyu Tolgoi mine, a joint venture between Rio Tinto Group, Turquoise Hill Resources, and the Government of Mongolia.Until 2010 copper was Mongolia's
Mining investment in Peru is expected to grow 9% this year when compared to 2016, marking the end of a three-year decline than began in 2014, to reach $10 billion next year thanks to these projects.
In this paper we develop a dynamic model to assess the financial viability of a mining project in exploration stage using the real options approach. The model simulates the decision making process and determines the value of the real options associated with the mining project. The firm has the option to defer investment, and once invested, to abandon or expand the project. On

This paper shows how CBA can be applied to mining projects. The main examples are from coal mining but the evaluation process is general. Sections 2 and 3 describe the cost-benefit approach and estimation methods for the major costs and benefits of mine projects respectively. Section 4 discusses six major issues in the evaluation process

Classification of renewables in mining projects – paper. As the number and variety of mining in renewable projects develops there is a greater need for a common nomenclature and taxonomy in order to better understand the market potential. For developers looking to build business plans around renewables in mining, for policy-makers aiming to move the extractive industries

The Berejiklian government will pause new approvals for mining under Sydney's catchment until well into 2020 as it considers an advisory panel's report
Financial analysis of mining projects can be known by studying the financial statements. Financial statements are official records of the financial actions of a company, firm or other unit over a period of time which provide a general idea of a company or person's financial situation in mutually short and long term. They give a precise representation of a company's condition and working

Mining lenses are divided into panels and are mined using a bottom-up sequence in a continuous 45 degree retreating either towards or away from level access drives. The nature of this mining sequence causes fluctuations in the grade profile of the short-term schedules. Each stoping panels contain between 3 and 5 sub-levels with crown pillars left in-situ between the backs of
