Pan American Goldfields Clarifies Its Disclosure

VANCOUVER, BRITISH COLUMBIA--(Marketwired - Nov. 4, 2013) - As a result of a review by the British Columbia Securities Commission ("the BCSC"), the securities regulatory authority in the Province of British Columbia, Pan American Goldfields Ltd. (the "Company") (OTCQX:MXOM) is issuing the following news release to clarify the Company's disclosure, based on discussions between the management team and the BCSC.

Technical Report Compliance:

The review by the BCSC has identified a number of technical compliance and filing issues with respect to the technical report entitled "Cieneguita Project, Preliminary Economic Assessment, Chihuahua, Mexico", by M3 Engineering and Technology Corporation, dated May 16, 2013 (the "Technical Report"). The updated mineral resource estimate and preliminary economic assessment are not supported by a compliant, fully independent NI 43-101 technical report, contrary to NI 43-101, and should not be relied on until they are independently verified and supported by an amended technical report. To correct the current situation going forward, the Company is working with the relevant Qualified Persons and is correcting the issues and intends to file an amended Technical Report on or before 25th November, 2013.

Clarification of previous disclosure:

The review by the BCSC has identified a number of disclosure issues with respect to the Technical Report, also occurring in the Company's news releases, website, and investor materials. Specifically:

1. Non-compliant disclosure of Preliminary Economic Assessment (PEA)

In its previous news releases, on its website, and investor presentation, the Company referred to the results of a PEA in a manner contrary to NI 43-101. Disclosure did not include prominent cautionary language required by section 2.3(3) and 3.4(e) of NI 43-101. The Company clarifies that the preliminary economic assessment is preliminary in nature, that it includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realised. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

Disclosure of PEA results also included potentially misleading promotional information, which disclosed or implied the PEA demonstrates economic viability. This is contrary to the preliminary nature of a PEA and the required cautionary language and such disclosure is hereby retracted and investors are cautioned that such disclosure should not be relied upon. Going forward, the Company will ensure that the required proximate cautionary language will appear with all disclosure of results of the PEA.

2. Reporting Gross In-Situ Metal Value

The company's June 12, 2013 news release highlighted a gross metal value for the material used in the PEA. However, the use of gross in-situ value is misleading because it fails to take into consideration operating and capital costs, recoveries, smelter costs and other factors relating to the potential mining, extraction and recovery of metals and such disclosure is hereby retracted and investors are cautioned that such disclosure should not be relied upon.

3. Non-compliant disclosure of Mineral Resources

The Company occasionally reported mineral resources for its Cieneguita mineral property that were contrary to section 2.2 and 3.4 of NI 43-101 because the estimates omitted classification, tonnage, and grade and only disclosed gross contained metal quantities. In addition, estimates did not disclose resource classes separately.

"We are committed to achieving the highest standards of excellence in meeting the requirements of the regulatory authorities" commented CEO, Emilio Alvarez. "As part of this process, our technical disclosure must also comply with the requirements of Canadian National Instrument 43-101 "Standards of Disclosure for Mineral Projects" in all respects, and we are committed to meeting that objective and enhancing the value of the Company for all our shareholders."
