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 withinn a global Measured Indicated and Inferred Resource of 68.6 million tonnes at 5.7% Pb+Zn, as shown in the tables below.

Extensive drilling had been carried out by ORGM on prospects outside Tala Hamza. This data is being reviewed by Terramin and an exploration programme of these areas will commence following completion of feasibility studies at Tala Hamza.
