VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 18, 2012) - Petaquilla Minerals Ltd. ("Petaquilla" or the "Company") (News - Market indicators)(OTCBB:PTQMF)(FRANKFURT:P7Z) announces for its second quarter of fiscal 2012 a net income of US$8.9 million, representing an improvement of US$32.2 million compared to the same period of fiscal 2011. This improvement was mainly due to an increase of 19% in gold poured combined with higher gold prices and a reduction of 14% in cash cost per ounce sold.

Gold poured during the second quarter of fiscal 2012 continued an upward trend totaling 18,100 ounces, an increase of 1% compared to the previous quarter and 19% higher than production obtained during the same period of fiscal 2011. Actual gold mined equaled 37,056 ounces contributing to reach 63,878 stockpiled gold ounces as part of the Company's plans to increase future production at its Molejon gold mine.

Gold sold and revenues generated of US$25.3 million during the second quarter of fiscal 2012 reflected increases of 21% and 46%, respectively, compared to the second quarter of fiscal 2011. Cash cost per ounce of gold sold equaled US$557, within the Company's guideline range of US$550 - US$600. Operating profit for the second quarter of fiscal 2012 at US$10.6 million improved by 8% and 125% compared to the first quarter of fiscal 2012 and the same period of fiscal 2011, respectively.

Cash flow from operations was positive at US$14.1 million for the six months ended November 30, 2011, and was invested towards production capacity with the objective of increasing gold production to the range of 100,000 ounces for fiscal 2012.

During the second quarter of fiscal 2012, the Company initiated its on/off leach operation with the leaching of a pad containing approximately 40,000 tonnes of ore and the construction of a second leach pad with a capacity of 300,000 tonnes of ore. The Company estimates that the combined ore on the two leach pads will contain approximately 17,000 gold ounces with a planned recovery rate of 70%. Production from the on/off leach operation is expected to progressively increase to 2,000 ounces per month during the second half of fiscal 2012.

During the second quarter of fiscal 2012, as part of the Company's planned expansion of its Molejon gold mine production system by increasing grinding and processing capacity and adding the aforementioned on/off leach operation, the installations of a third drum scrubber and an additional horizontal Carbon-in-Column circuit ("CIC circuit") were completed. The scrubber will significantly improve the processing of clays while the CIC circuit will increase gold absorption capacity by 80% and improve gold recovery rates from both the milling system and on/off leach operation. Additionally, during the second quarter of fiscal 2012, the Company initiated the procurement of a fourth ball mill plus the corresponding additional two leach tanks and two Carbon-in-Pulp tanks which, in the second half of fiscal 2012, are anticipated to add 1,000 tpd processing capacity, representing approximately 2,000 additional ounces of gold recovery monthly.
