• Sirios issued 9.9% of its share capital to Golden Valley as of December 31, 2013 (2,898,374 shares, currently representing approximately 4% of Sirios);
  
  
• Sirios must make a payment to Golden Valley of $500,000 (cash or equivalent in SOI shares) prior to June 13, 2016 (notwithstanding the foregoing, Sirios shall have the obligation to pay in cash that portion of the $500,000 which would result in Golden Valley becoming an insider of Sirios).

Update on Subsidiaries:

• Abitibi Royalties Inc.: As announced in Q1/2015, Abitibi Royalties Inc. completed a significant transaction with Canadian Malartic GP, owned equally by Agnico Eagle Mines Ltd. and Yamana Gold Inc., pursuant to which Abitibi Royalties sold its interest in the Malartic CHL project to Agnico Eagle and Yamana Gold in exchange for shares in Agnico Eagle and Yamana Gold and a new 3% NSR on the Malartic CHL project;
  
  
• Abitibi Royalties holds a 3% NSR on the Odyssey North discovery that is located east of the main Canadian Malartic open pit. Agnico Eagle Mines Limited recently reported that drilling continues at the Odyssey discoveries and that data is currently being compiled and interpreted, with interesting results continuing to be encountered at depth. No additional assay results have yet been released and there are no assurances that all or any of the recent drilling since April 2015 has encountered mineralization on the property covered by Abitibi Royalties' 3% NSR.
  
  
• Drilling at the Odyssey discoveries began in April 2015 with an initial budget of approximately Cdn$3.5 million that includes 25,500 metres of drilling. The goal of the drilling is to define the potential size, grade and extent of the Odyssey deposits that could become feed for the Canadian Malartic mill. Odyssey North is believed to have bulk tonnage underground potential similar to Agnico Eagle's Goldex mine, which is located approximately 15 kilometers east.
