The Canadian mining sector has to be innovative and invest in the development of sustainable mining technologies to maintain its international leadership. Natural Resources Canada (NRCan) collaborated with the Canada Mining Innovation Council (CMIC) to define the Green Mining Initiative (GMI) and in order to focus its R&D activities on industry and other stakeholders? needs. The GMI was launched in 2009 to spur innovation in the mining sector and further enhance its environmental performance. The initiative, led by CANMET- Mining and Mineral Sciences Laboratories (MMSL), takes a holistic approach looking at the entire mining life cycle, from design to closure and beyond, through four innovation and research pillars: ? Footprint Reduction, ? Innovation in Waste Management, ? Mine Closure and Rehabilitation, and ? Ecosystem Risk Management. The Canada Mining Innovation Council has also been creating a new initiative on Sustainable Mining, which will bring further focus to environmental aspects of mining, and engaging wide range of research providers to develop research programs complementary to GMI goals.

This document presents estimates of future "total cash cost per ounce" and "minesite cost per tonne" that are not recognized measures under United States generally accepted accounting principles ("US GAAP"). This data may not be comparable to data presented by other gold producers. These future estimates are based upon the total cash costs per ounce and minesite costs per tonne that the Company expects to incur to mine gold at the applicable projects and do not include production costs attributable to accretion expense and other asset retirement costs, which will vary over time as each project is developed and mined. It is therefore not practicable to reconcile these forward-looking non-GAAP financial measures to the most comparable GAAP measure. A reconciliation of the Company's total cash cost per ounce and minesite cost per tonne to the most comparable financial measures calculated and presented in accordance with US GAAP for the Company's historical results of operations is set forth in the notes to the financial statements included in the Company's Annual Information Form and Annual Report on Form 20-F, for the year ended December 31, 2009, as well as the Company's other filings with the Canadian Securities Administrators and the SEC.

Au printemps 2011, la Corporation minière Osisko met en production le gisement Canadian Malartic, qui devient la plus importante mine d?or à ciel ouvert au Canada. Pour lui faire place, elle a déménagé un quartier de 205 maisons et construit 6 nouveaux bâtiments institutionnels. Les démarches ont commencé en 2006. La compagnie a d?abord établi l?emplacement du nouveau quartier résidentiel, en collaboration avec la Ville de Malartic, puis fait la conception de ce quartier de manière à refléter au mieux les caractéristiques du quartier à déménager. Elle a ensuite effectué une opération d?assignation consistant à proposer à chaque propriétaire intéressé un lot dans le nouveau quartier. Au total, 140 résidences ont été déménagées en 2008 et 2009 et 65 été rachetées par la compagnie, le tout par des ententes de gré à gré sauf pour un seul cas. La réussite d?une opération d?une telle importance sociale n?a été possible que parce que la compagnie s?est assurée d?un soutien massif de la population et des autorités pendant tout le processus. Cette expérience peut être fort utile pour les nombreux projets miniers dont l?insertion dans la communauté est un enjeu important.

Over the last 100 years industry in general has been trying to advance the ability to maintain systems through management processes. Mining has looked to utilize onboard data systems in our mobile mining fleets to compliment these processes. Combining the two concepts build the concept that Rio Tinto refers to as asset health. These programs can generate a cost shift between $20,000 and $100,000 per piece of equipment annually. Even with the documented savings many operations struggle to justify the systems, why?

Many mines combine open pit with underground mining, and on many occasions the underground mine is an extension of the open-pit. In these circumstances the decision about where the open-pit stops and the underground starts is crucial and driven by many factors. This paper looks at some of the ways that this cut-over can be calculated and specifically examines the calculation of it using modern mine optimization software. The paper provides a case study which will review various outcomes using these techniques, and demonstrates the influence of various factors on the optimal transition cut-over point.

This paper summarizes current underhand paste backfill mining as applied to Goldcorp Inc?s Red Lake Mine, Newcrest Mining Ltd?s Kencana Mine and the Lanfranchi Nickel Mine as well as ongoing research at the University of British Columbia?s Norman B. Keevil Institute of Mining Engineering. The Red Lake Mine utilises a 6 m wide undercut with a 2 MPa unconfined strength paste in order to selectively mine its high grade, high-stress orebody. Kencana?s orebody is located in a poor rock mass environment. An 8 m wide, 2 MPa unconfined strength paste sill allows a safe working condition for its high grade orebody. The Lanfranchi Nickel Mine utilises a cable-supported, 2 MPa paste, with 12 m span sills, to optimize the mining of the squeezing rock mass. This paper details the rock mechanic hazards, ground support techniques, paste practices and unique conditions for each mine. Further, an update of ongoing research at the University of British Columbia, focussing on the optimization of safe mining in underhand cut-and-fill mining in high-stress/weak rock masses, is presented.

A cornerstone in the LKAB Green Pellet concept is to produce pellets with a small footprint in terms of energy con-sumption, CO2 emission and emission of other elements harmful to the environment, like dust, sulphur dioxides, nitrogen oxides, chloride and fluorine. The concept also encompasses our determination to make pellet products that contribute to low environmental impact and low energy consumption in our customer?s processes. The presentation will focus on the pelletizing process. It will describe both how we have attempted to decrease the generation of unwanted components in the process gas, and how we have tested or evaluated equipment for external gas cleaning. We will discuss and give examples from recent and on-going efforts and outline some of the future challenges we see, to meet our own environmental standards and also the tough demands imposed by EU and national legislation, while striving to boost production.

In this study, the effect of silicon on the microstructure, mechanical properties and hot tearing susceptibility of permanent mould cast AZ91E magnesium alloy was investigated. Varying amounts of silicon (0.5, 1.0 and 1.5 wt.%) were added to AZ91E in the form of an Al-53 wt.% Si master alloy. The phase formation, grain size and solidification behavior of each alloy were characterized and related to their tensile properties and hot tearing susceptibility. The results showed that the addition of silicon resulted in the formation of Mg2Si particles. The presence of these particles led to an increase of the hardness, but was detrimental to the tensile strength and elongation of AZ91E. However, silicon significantly reduced the hot tearing susceptibility of AZ91E. This was attributed to the reduction of the grain size and the decreased freezing range of AZ91E, which contributed to improve the interdendritic feeding during the last stage of solidification.
