Iberian Minerals Reports Increased Aguas Tenidas Resources and Confirms Reserves, and Plans to Increase Mine Plan to Target 2.2 Mtpa Production

TORONTO, ONTARIO--(Marketwire - Sept. 11, 2009) - Iberian Minerals Corp. (TSX VENTURE:IZN) announced today that it has received a report dated September 11, 2009 entitled "Report 43-101 Technical Report on the Mineral Resources and Reserves of the Aguas Tenidas Project, Spain" (the "43-101 Report"). Authored by Adam Wheeler, Mining Consultant, C.Eng and Eur. Ing., the 43-101 Report provides an update on resources and reserves as at June 30, 2009, and details new planned production levels for the Aguas Tenidas Mine.

Mr, Wheeler has authored several technical reports for Iberian for the project. A full copy of the 43-101 Report may be found on www.sedar.com.

Evaluation work was carried out, and the 43-101 Report was prepared in compliance with Canadian National Instrument 43-101, and the mineral resources in this estimate were calculated using the Canadian Institute of Mining, Metallurgy and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions and Guidelines prepared by the CIM Standing Committee on Reserve Definitions and adopted by CIM Council December 11, 2005.

The focus for the work of Mr. Wheeler was to confirm resources and corresponding reserve updates at Aguas Tenidas.

In summary:

  • Total Resources (Measured and Indicated) - 27.5 Mt including the cupriferous, polymetallic and stockworks resources. Importantly, the readily accessible copper stockworks resources have increased by over 100%.
  • Total Inferred Resources - 10.62 Mt, in all categories of mineralization - an increase of approximately 6 Mt from the previous estimates.
  • Total Reserves (Proven and Probable) - 19.21 Mt, a slight 1% increase from prior estimates.
  • Plans to increase mine production to 2.2 Mtpa, resulting in a 10 year mine life when taking into account a ramp-up period from the current 1.7 Mtpa target.

Updated estimations are:

Notes. Measured and indicated resources shown are inclusive of reserves. Mineral resources were evaluated using the following cut-off grades: Polymetallic 3% Zn, Cupriferous 1% Cu, Stockworks 1% Cu. Mineral resources which are not mineral reserves do not have demonstrated economic viability. The estimate of mineral resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.

Notes: Same cut-offs as for measured + indicated. Stockworks only currently modelled between 690,800mE and 691,060mE. The quantity and grade of reported inferred resources in this estimation are uncertain in nature and there has been insufficient exploration to define these inferred resources as an indicated or measured mineral resource and it is uncertain if further exploration will result in upgrading them to an indicated or measured mineral resource category

Notes: In determining mining reserves, reserves were blocked out on the basis of contained NSR value, with reference to the combined stoping and processing costs. The NSR values were calculated using metal prices of $4,500/t Cu, $1,650/t Zn, $1,650/t Pb, $12.5/oz Ag, $750/oz Au. Copper ore is split approximately 82%:18% Cupriferous:Stockworks

A life-of-mine plan and corresponding mining schedule have been developed for these reserves. Based on the ore production schedule, leading to an overall 1.7 Mtpa production, the expected life-of-mine from the time of writing would be 12 years. However, an expansion is currently being planned, which would lead to production rate of 2.2Mtpa total ore, and a revised mine life of 10 years, based on the same 19.21Mt mining reserve. The expansion is subject to regulatory approval; while the fact and timing of such an approval is not certain, the Company is confident of obtaining all required approvals in early 2010.

Mr. Wheeler has recommended an on-going in-fill drilling program from the investigation gallery, designed to upgrade the resource class status of the massive sulphide zones in the western part of the mine. Further deeper drilling, targeting copper stockworks resources, is designed to both increase the stockworks resource base and assist in upgrading the resource class levels of already delineated stockworks resources. Further mine planning work on the copper stockworks is expected to enable the conversion of some of the stockworks resources into reserves.

In light of the foregoing, the Company is updating Guidance for the Aguas Tenidas Mine for 2009 and 2010. It is expected that, based on Iberian's projections, ore processed will be 900,000 tonnes in 2009, down 100,000 tonnes from the earlier guidance and in the range of 2.0 million tonnes in 2010 during ramp-up to a target of 2.2Mtpa. Although actual costs remain to be calculated, current budget indications are that costs during the first year after expected commencement of commercial production, based on expected ore processed, will be as follows:

 Costs 2010
 Mining 23
 Plant 20

Daniel Vanin, President of Iberian said: "We are delighted with the findings from the 43-101 Report. Not only have we confirmed our reserves, we have increased our resource and inferred categories. This leads us to plan for aggressive on-going delineation of all resource categories to enhance our reserves, and we are confident of our ability to extend our mine life. Based on the current resource and reserve estimates and indications for the project, we have decided to plan to increase production at Aguas Tenidas from the current target of 1.7 Mtpa to a target of 2.2 Mtpa. We have extra capacity in the plant and a mining plan which allows expansion to this rate. There will be some capex required but we currently view this need to be minor, and included in the life of mine plan. We are now planning for implementation, and the necessary regulatory approvals.

For 2009, we are on track to mine and process 900,000 tonnes of ore. We are still aiming for commencement of commercial production in Q4. The copper circuit is functioning well and consistently. The polymetallic circuit is producing saleable bulk copper/lead, and zinc concentrates, and we will be announcing further final modifications shortly. We continue our work to optimise this circuit to produce three individual concentrates as originally planned, and we are confident that we have the answers and plan to produce the desired result by the end of 2009.

Today's news simply confirms our belief in the Aguas Tenidas Mine, and the future potential for this operation for Iberian and its shareholders."
