Pan American Goldfields Ltd Announces Appointment of Dr. Alexander Becker as Advisor to the Board of Directors

BROOMFIELD, Colorado, May 3, 2011 - Further to its press release of March 3rd 2011, Pan American Goldfields
Ltd (OTCBB:"MXOM") (the "Company") is pleased to announce the appointment as
advisor to the board of Dr. Alexander Becker. Dr. Becker, who has a PhD in
Structural Geology, has an extensive, varied and highly successful history as
an exploration geologist. Most recently he co-founded Manas Petroleum and was
responsible for the identification and acquisition of a portfolio of high
impact projects in Chile, Albania, Mongolia and Central Asia. Prior to this
he was a director of Perseus Mining Limited when it was formed in 2002. Dr.
Becker also identified and acquired the original assets of Perseus spin out
Manas Resources, which have so far resulted in two gold discoveries with JORG
resources of 1.13Moz.

In 1997, Dr. Becker was Vice President Exploration, Asia, for Apex Silver
Mines ("Apex"), which at the time was controlled by Paul & George Soros and
Thomas Kaplan. Apex accumulated what was then one of the largest, privately
controlled portfolios of silver exploration properties in the world. During
this period he also acquired the Sandalash License, Northern Kyrgyzstan,
having identified the gold potential of its known antimony occurrences most
prominently the Chaarat. Chaarat Gold Holdings later acquired the Chaarat and
a 4.4 million ounce gold resource was subsequently outlined.

In 1994 - 1995, Dr. Becker was also a consultant to Santa Fe Gold prior
to its acquisition by Newmont. He also acted as a consultant to Barrick Gold
(Asia) in the late 1990s.

Dr. Becker emigrated from Russia to Israel in 1991, where he became a
senior scientific researcher at Ben Gurion University and won the Peres Award
for tectonic research. In the Soviet Union he served as Geologist in Chief of
the mapping division in Northern Kyrgyzstan. Though Dr. Becker has an
extensive background in precious metals exploration, he is also credited with
the discovery of two oil fields in addition to being awarded by the Soviets
as the region's top mapping geologist.

Dr. Becker has authored numerous papers in international scientific
journals including Geological Society of America, Tectonophysics, Structural
Geology, and International Geology Review. He holds an M.Sc. in Geology from
the Tomsk State University and a Ph.D. in Structural Geology from the Academy
of Science in Frunze, Kyrgyzstan.

"At Pan American Goldfields our focus is building shareholder value,
first through developing our Cieneguita silver and gold mine and second,
through the identification, acquisition and then development of exceptional
high impact exploration assets," commented Pan American President Miguel Di
Nanno. "I am thrilled that Dr. Becker has committed to assist us in this
effort," Di Nanno stated.

On behalf of the Board of Directors

Miguel Di Nanno, President
