Blackbird Chromite Deposit
The Blackbird chromite deposit was discovered in 2008 and will be the second mine in the Noront pipeline. It is one of a number of large tonnage, high-quality chromite discoveries in the Ring of Fire. It offers significant potential due to its size, location (less than 1 km from Eagle’s Nest) and grade.

|* Resources are based on a 30% Cr2O3 cut-off grade.Please see the report titled “NI 43-101 Technical Report Feasibility Study McFaulds Lake Property Eagle’s Nest Project James Bay Lowlands Ontario, Canada,” dated October 19th, 2012 (with an effective date of September 4, 2012) (the “Technical Report”) for details regarding the mineral resource estimate above (14.1). Please see Section 14.1 of the Technical Report for details of the mineral resource estimate above (effective date September 4, 2012), including a description of the key assumptions, parameters and methods used to estimate the mineral resources.
Mineral resources that are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, socio-political, marketing or other relevant issues.
An updated Blackbird chromite NI-43-101 resource estimate, completed in March 2012, tripled the previous 2009 estimate and showed a 44 Mt resource with grades in excess of 35% Cr2O3, and chrome-to-iron ratios of approximately 2.0. In addition, the chromite mineralization at Blackbird remains open along strike and at depth.
Initial metallurgical test results indicate that a marketable high-grade chromite concentrate product with grades in excess of 50% Cr2O3, recoveries greater than 80%, and chrome-to-iron ratios greater 2.1 could be produced at Blackbird.
Blackbird may be suitable for underground bulk mining techniques and could share above and below ground infrastructure with Eagle’s Nest. It provides an opportunity for Noront to supply the global ferrochrome market.
Our goal is to produce a strategic plan and a comprehensive preliminary economic analysis (PEA) for all of the development options for the Ring of Fire chromite projects.
