Resources and Reserves at Oued AmizourResources and Reserves
Prior to Terramin's participation in the project, the Algerian government exploration company ORGM had completed 40 drill holes defining a body of mineralisation of around 30 million tonnes at Tala Hamza.
Extensive drilling by Terramin led to estimation of an initial Inferred Resource (satisfying JORC guidelines) in May 2007, updated to an indicated and Inferred Resource in late 2008.
The most recent Resource estimate (November 2009) gave a Measured and Indicated Resource of 51.1 Million Tonnes at 6.1% Pb+Zn within a global Measured Indicated and Inferred Resource of 68.6 million tonnes at 5.7% Pb+Zn, as shown in the tables below.
Following the completion of the Definitive Feasiblity Study in September 2010 a Probable reserve was estimated for the block cave mine.

Regional exploration has started with the objective of defining near surface mineralisation to feed the plant.
- a programe of systematic stream sediment sampling is underway
- preliminary results of the survey delineated a target area(Lbarkouk) whichwas drilled in 2010. Initial mapping of the area indicated a large zone ofalteration (2km long). Drilling of one project confirmedthe predenceof a large halo of low grademineralisation.
- work at Bouzenan to confirm the existing prospect.
