Petaquilla Minerals Ltd. Update on Lomero-Poyatos Project

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 10, 2012) - Petaquilla Minerals Ltd. (TSX:PTQ)(OTCBB:PTQMF)(FRANKFURT:P7Z) ("Petaquilla" or the "Company") is pleased to announce that representatives of the Company recently met with members of the Andalusian Autonomous Government, the regional government body of Andalusia, Spain, to settle the final details regarding the initiation of commercial mining operations at the Company's Lomero-Poyatos concession.

The Company was granted a Unified Environmental Authorization in December 2011 and all instructions and recommendations from the Andalusian Autonomous Government have since been approved and sanctioned. All requisite environmental, technical and economic permits have also since been approved by the Andalusian Autonomous Government and the Company is presently awaiting administrative authorization to commence operations. The Company anticipates it will be able to start Lomero-Poyatos operations within the next 6-8 weeks with the dewatering of galleries, construction of a water treatment plant, and the initiation of development drilling.

Video footage (English version with subtitles as required) featuring interviews with José Juan Díaz Trillo, Minister of the Environment of the Andalusian Autonomous Government, Pascual Montañés from the Company's operations in Iberia, María José Asensio, delegate of the Economy, Innovation and Science in Huelva, and Pedro Romero, Mayor of Cerro del Andévalo, can be located at the following link:

Lomero-Poyatos Mine

Behre Dolbear International Limited ("Behre Dolbear") prepared a National Instrument 43-101 compliant Technical Report on the Lomero-Poyatos mine project in 2011 ("NI 43-101 Technical Report"). The Lomero-Poyatos mine previously produced about 2.6 metric tonnes of pyrite ore, mostly by underground mining methods. The Lomero-Poyatos deposit is at the exploration stage and the mineral resource estimate is based on historical data and relatively wide-spaced drilling. Therefore, the mineral resource is categorized as an Inferred Mineral Resource.

Mineral Resource Estimate

The approximate size of the Lomero Poyatos deposit, based mainly on historical drill-hole data, has been estimated by three independent consultants in the past nine years. The results are summarized below as two separate scenarios, namely open-pit and underground.

Open-pit Scenario:
SRK (2002) Inferred Mineral Resource: at a €50 value cut-off = 20.6 Mt at 3.1 g/t Au, 69.9 g/t Ag, 3.3% Zn, 1.2% Cu, 1.2% Pb. Containing 2.1 Moz Au.
Gemcon (2010) Inferred Mineral Resource: at 1 g/t Au cut-off grade = 20.9 Mt at 3.08 g/t Au, 62.38 g/t Ag, 2.5% Zn, 0.7% Cu, 0.7% Pb. Containing 2.07 Moz Au.
Underground Scenario:
SRK (2002) Indicated Mineral Resource: at a €70 value cut-off = 1.85 Mt at 3.4 g/t Au, 52 g/t Ag, 0.8% Cu, 1.4% Pb, 2.3% Zn. Containing 0.203 Moz Au.
WAI (2006) Indicated Mineral Resource: at 1.5g/t Au cut-off = 3.71Mt at 3.26 g/t Au, 27.9 g/t Ag, 0.87% Cu, 1.16% Pb, 1.57% Zn. Containing 0.39 Moz Au.
Gemcon (2011) Inferred Mineral Resource: at 1 g/t Au cut-off grade = 6.07 Mt at 4.25 g/t Au, 88.74 g/t Ag. Containing 0.83 Moz Au.


As a consequence of the mineral diversity, the geological and mineralogical domains need to be defined so as to provide separate tonnage and grade estimates for each of the ore types. Representative metallurgical samples need to be extracted from each of these ore type domains for metallurgical testing. In addition, further validation of the nature and distribution of the gold, silver, copper, lead and zinc mineralization is required, in order that the Inferred Mineral Resources can be upgraded.

The NI 43-101 Technical Report recommends that additional drilling (totaling 40,000 metres) be carried out, including some duplicate drill-holes, twinning selected surveyed historical holes, in order to cross-correlate the historical data with confirmatory data and some additional drill-holes to better define the physical extent of the solid at depth and along strike.

It is proposed to achieve this in two stages: as a stage 1 drilling programme and scoping study and a stage 2 pre-feasibility study with further drilling and test-work.

Qualified Person

Richard James Fletcher, of Behre Dolbear, is a "qualified person" as defined in NI 43-101 and accepts responsibility for all sections of the technical report. Behre Dolbear affirms that Mr. Fletcher:

  • is a Fellow of the Australasian Institute of Mining and Metallurgy; and
  • has more than 40 years experience in the estimation, assessment and evaluation of mineral resources and ore reserves that is relevant to the styles of mineralization and the types of deposits under consideration.
