Tantalum (Ta) and Niobium (Nb) Activities

CIF extracts Ta and Nb containing ores from the Mibra mine and either

converts them into high-purity Ta and Nb oxides via chemical processes or

sells them as concentrate

Mibra mine, Nazareno

Production plant, São João del Rei

Acid leaching & solvent extraction

Mibra Mine

The mine has several orebodies with Orebody A being the main source of pegmatite

(6.32 million tons)

Further exploration work on Orebody A, B & C as recommended by SRK

Activities at the mine include surface mining and gravimetric, electrostatic, and

electromagnetic concentration

11.6 million tons of hard orebodies

New drilling and surveys lead to existing resources much

higher than previously expected

Completion of this work is expected by Q1 2012

→ 8.6 million lbs Ta2O5 contained in ore

The Mibra mine has several other hard and soft pegmatite orebodies

Orebodies B and C-south

Kaolinized or Soft Pegmatite

7.6 million tons of soft orebodies

Mineralogy:

Quartz (50 – 60%)

Kaolinite (35 – 40%)

Kaolin resources estimated at 2.7-3.0 million tons

White Mica (1 – 5 %) and Iron Oxides (0 – 2%)

Mibra Mine’s business model will position it as reliable long term source of Tantalum for the industry,

Multi product concept will ensure Mibra’s competitiveness, financial and environmental sustainability,

New ceramic products under development will consolidate and strengthen the business model,

CIF targeting the following production levels for Ta₂O₅:

2012 – 400klbs pa

2013 – 500klbs pa

2015 – 550klbs pa based on additional soft pegmatite production
