Sustainable Development

Conserving and Creating

At Osisko we believe it is important to promote biodiversity in the environments where we operate. Promoting biodiversity is about more than simply keeping track of disturbed and rehabilitated lands. It means conserving and creating a variety of environments where a wide range of plants and animals can grow and live.

Osisko’s advanced planning will allow reclamation to occur at the Canadian Malartic site long before the mine is ready to close. In 2010, Osisko initiated a research project with the Université du Québec en Abitibi-Témiscamingue (UQAT) aimed at forestation of the Malartic tailings.

Osisko recycles

Osisko has active recycling programs at both the Canadian Malartic and Hammond Reef sites. We recycle materials that are in demand and participate in local waste reduction initiatives. Wire, metal and wood is removed from our waste stream at site for industrial recycling. We also recycle paper, cardboard and plastic in our offices.

 

Recycling at Canadian Malartic in 2011


Métaux recyclés : 497,14 tonnes (35 %)

Câblage électrique recyclé : 60,32 tonnes (4 %)

Déchets enfouis : 294,75 tonnes (21 %)

Bois recyclé : 508,48 tonnes (36 %)

Papier, carton et plastique recyclés : 63,61 tonnes (4 %)
 

Mine Closure Planning

Osisko’s approach to mine closure is to be pro-active and plan for the stable, long-term restoration of its mine sites.

  
 

We believe that this approach supports a healthy ecosystem, includes the values of our local communities, and provides a positive example for mining in the future.

 

Osisko recently made mining history in Québec with its Canadian Malartic Mine. Even though it is not yet required by law, Osisko has agreed to provide a financial guarantee that will cover 100% of the estimated costs (a total of $46.44 million) for rehabilitating the Canadian Malartic Mine site instead of the 70% currently required by Québec law. On October 12, 2011, Osisko deposited the amount of $22.1 million with the Québec government, representing almost 50% of the financial guarantee of $46.44 million, to cover the entire estimated future cost of rehabilitating the Canadian Malartic Mine site. The balance of the guarantee will be remitted by two subsequent payments to be made in 2012 and 2013. Our closure plan and closure cost estimates are regularly updated to reflect the reality of the Canadian Malartic Mine.
