AMG Advanced Metallurgical Group N.V. Announces tantalum mineral resources update at volte grande mine - AMG Corporate

Amsterdam, 22 April 2013 — AMG Advanced Metallurgical Group N.V. (“AMG”, EURONEXT AMSTERDAM: “AMG”) announces that AMG Mineração, a subsidiary of AMG Mining, has updated its mineral resource estimates for its Volte Grande mine in Brazil in accordance with CIM Definition Standard and Canadian Securities Administrators’ National Instrument 43-101 (“NI 43-101”) Guidelines.

The Technical Report on Mineral Resources states that AMG Mineração’s Volte Grande mine has 14.7 million tons of measured and indicated resources.  Those resources include tantalum, niobium, tin and lithium.  This report is based upon drillings and research done during the 2011-2012 core drilling campaign and certain economic assumptions that reflect today’s current market prices and extraction costs.

Compared to the previous Mineral Resource Statement, which was completed in 2010:

* the measured and indicated mineral resource for the Volte Grande project increased by 8.9 million tons, to 14.7 million tons, an increase of approximately 150%,
* the inferred mineral resource increased by 4.0 million to 4.7 million tons, an increase of approximately 550%, and;
* the combined measured, indicated and inferred mineral resource increased by 12.9 million tons to 19.3 million tons, an increase of approximately 200%.

AMG estimates that the current life of the mineral resource is approximately 20 years, based upon current tantalum concentrate production levels, extraction and processing costs, and current economic conditions.  The detailed table of the mineral resources is below:
