Iberian Minerals Publishes Preliminary 2010 Production Results and 2011 Guidance for Condestable and Aguas Tenidas Mines

TORONTO, ONTARIO--(Marketwire - Jan. 20, 2011) - Thursday, January 20, 2011 – Iberian Minerals Corp. (TSX VENTURE:IZN) today announced preliminary production results for 2010 and issued production guidance for 2011.

Mr. Daniel Vanin, President and CEO, stated "We are pleased with the production results at both Iberian operations in 2010. The Aguas Tenidas operation, having been expanded and with enhancements to the polymetallic circuit, is now delivering consistent production results while Condestable mine continues to deliver reliable results."

Peruvian Operations:

Operations at the Condestable Mine remain in a steady state with tonnage of ore processed slightly over plan in 2010. Copper production for 2010 was 98% of previously issued guidance due to lower copper head grade. Silver production in 2010 exceeded plan by 45%. The average copper ore head grade for 2010 was 1.16% versus a budgeted copper ore head grade of 1.23%.

The following are the preliminary production results for the Condestable Mine operation for the year ended December 31, 2010:

Production Unit Q1 Q2 Q3 Q4 2010
Ore processed T 551,700 550,700 564,500 567,600 2,234,500
Concentrate DMT 21,300 23,000 24,600 23,400 92,300
Contained copper T 5,335 5,830 6,100 5,890 23,155
Fine gold Oz 3,260 4,020 3,390 3,210 13,880
Fine silver Oz 66,050 65,660 76,340 82,950 291,000

Spanish Operations:

Operations at Aguas Tenidas realized significant achievements in 2010. A 30% plant and mine expansion project was completed during the year which now allows for daily operations at 6,000 t (equivalent of 2.2 Mtpa).

The following are the highlights for the Aguas Tenidas Mine operation for the year ended December 31, 2010:

  • Preliminary production results:

  • In Q4 the operation realized its best quarterly production results with record combined throughput of processed ores and record production of zinc.
  • The polymetallic circuit delivered metallurgical results in line with targets.
  • A lead concentrate of saleable quality was produced for the first time in Q4 with a concentrate grade of 19%. Work is on-going to improve the grade to a target of 40% through the installation of new column cells in Q1 of 2011.
  • Plant throughput on the copper circuit in Q4 was impacted by a breakdown in the drive components of the copper SAG mill.

2011 Production Guidance

The Company is targeting the following guidance figures for the Condestable and Aguas Tenidas mines in 2011:

Condestable Mine:

  • Production:
Production Unit 2011
Ore processed t 2,290,600
Concentrate DMT 93,700
Contained copper t 23,900
Fine gold oz 15,500
Fine silver oz 289,300
  • Average head grade of approximately 1.15% Cu, and recovery rate of 90% per year. 
  • Cash operating costs of $1.15 per payable pound of copper.

Approved capital expenditure budget for Condestable Mine for 2011 is $10.2 million which includes the completion of a 10% plant expansion. Plant expansion activities commenced in late 2010 with expected ramp-up to 6,600 tpd in Q3 of 2011. At a total budgeted cost of $11.7 million, the objective of the plant expansion is to maintain current levels of copper metal production in light of decreasing average copper ore head grade in the mine. The expansion is being funded through leasing arrangements and operating cash flows.

Aguas Tenidas Mine:

  • Production:
Production Unit 2011
Ores processed (total) t 2,200,000
  - Copper Ores t 1,310,000
  - Polymetallic Ores t 890,000
Copper concentrate DMT 115,000
Zinc concentrate DMT 69,000
Lead concentrate DMT 8,500
Contained copper t 25,000
Contained zinc t 33,900
Contained lead t 3,700
Fine silver oz 730,000
  • Average head grade (copper ores) of approximately 2.0% Cu, and recovery rate of 83% per year.
  • Average head grade (polymetallic ores) of approximately 5.8% Zn and recovery of 66%; head grade of approximately 1.0% Cu and recovery of 42%. 
  • Cash operating costs of $1.75 for 2011 per payable pound of copper.

Approved capital expenditure budget for Aguas Tenidas Mine for 2011 is $28 million with a focus on advancing mine development for the medium term mining plan. Other major projects expected to be completed during 2011 are: lead circuit upgrades, completion of phase two of the raising of the tailings dam, new fleet of larger capacity ore/waste haulage trucks for the mine. These capital expenditures are expected to be funded by cash flow from operations.

Cash Operating Cost per pound of payable copper includes cash operating costs, including treatment and refining charges ("TC/RC"), freight and distribution costs, and is net of by-product metal credits (zinc, gold and silver). The Cash Operating Cost per pound of payable copper indicator is consistent with the widely accepted industry standard established by Brook Hunt and is also known as the C1 cash cost.
