PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Petaquilla Minerals Ltd. (the "Company") is currently in the process of finalizing its Transition Report on Form 20-F and anticipates filing the report on or before Monday, November 4, 2013. Due to the Company's recent change in fiscal year-end from May 31st to June 30th, and the additional financial information needed to be prepared, the Company's audited consolidated financial statements for the thirteen (13) months ended June 30, 2013, were completed on October 4, 2013. This four day delay in completing its audited consolidated financial statements for the thirteen (13) months ended June 30, 2013, plus the requirement to provide unaudited financial statements for the twelve month period ended May 31, 2013, and one month period ended June 30, 2013, pursuant to Part 6250.2 of Rule 15d-10(g) and 13a-10(g) of the Securities Exchange Act of 1934, as amended, has resulted in a delay of approximately four days in the filing of its Transition Report on Form 20-F.
