The correct table, as set out in the Company's National Instrument 43-101 ("NI 43-101") technical report entitled "Technical Report on the Mineral Resource Estimate for the Magusi Project, Abitibi Region, Canada" dated March 21, 2012, is as follows:

Area	Tonnes	Cu%	Zn%	Ag (g/t)	Au (g/t)
High Grade Copper	729,000	3.26	0.58	43.4	0.41
High Grade Zinc	580,000	0.39	8.57	42.1	2.34
Total Indicated	1,309,000	1.99	4.12	42.8	1.27
High Grade Copper	355,000	3.41	0.39	24.2	0.26
Total Inferred	355,000	3.41	0.39	24.2	0.26

Notes:

1. CIM definitions were followed for Mineral Resources.
2. Mineral Resources are estimated at a cut-off grade of $110 NSR/tonne.
3. Mineral Resources are estimated using an average long-term copper price of US$3.50 per pound, a zinc price of US$0.95 per pound, a gold price of US$1,300 per ounce, a silver price of US$21.00 per ounce, and a US$/C$ exchange rate of 1.00 to 1.00.
4. Grade interpolation was carried out with inverse distance squared (ID2) method.
5. Mag provided RPA with NSR multipliers per metal unit. The NSR multipliers, which vary with head grades and metal recoveries, are based on SGS Lakefield metallurgical tests. The NSR values were calculated for each assay as well as each block in the model.
6. Minimum underground mining width of two metres was used.
7. The East Zone resources were also included in the estimation but did not meet the cut-off criteria.

The mineral resource estimate has been carried out by Roscoe Postle Associates Inc. and reported in accordance with NI 43-101 requirements.  Bernard Salmon, ing., a Qualified Person under NI 43-101 has verified the data disclosed in this press release.
