Terreno Resources Corp. ("Terreno" or the "Company") (TSX VENTURE:
TNO) is pleased to provide an update on exploration activities at
La Poposa, a high sulphidation gold copper project located in San
Juan province, Argentina.
Terreno has recently completed its first work program at La
Poposa which commenced in Q4 2010 and consisted of geological
mapping, the completion of 72 trenches with continuous rock chip
sampling, as well as the completion of a CSAMT survey and a 7-line,
Titan 24 DCIP and MT survey (see figure 1:
http://media3.marketwire.com/docs/TNOfig1.pdf). The geological
mapping has led to a new interpretation on the geology which
highlights the potential for high grade feeder systems, hosted by
andesitic volcanics, occurring beneath a low grade massive silica
altered rhyolite cap. The trenching program has identified several
areas with low grade gold with widths up to 100 meters which could
occur above such feeder systems. Results from the geophysical
programs are still pending.
Highlights from the trenching program are shown in Table 1.

(i) Results from trench TA-03 were previously reported on March 3, 2011 and
are repeated here to provide context.
"We completed a large amount of work at La Poposa during our
first season and are encouraged by the results," stated Peter
Mullens, Vice President of Exploration. "The trench results confirm
the presence of a large and intense high sulphidation alteration
system over an area in excess of 10 square kilometers. Within this
area there are extensive zones of low grade gold mineralisation, as
shown in the trench results. This extensive low grade
mineralisation is interpreted as part of a large silica cap which
could occur above high grade feeder zones or a large disseminated
epithermal system - as is common in other systems within South
America. In addition there is potential for a large porphyry system
at depth. We will analyze results from this season in conjunction
with our improved understanding of the geology and the data from
our geophysical surveys to identify drill targets which we plan to
start drilling in late Q3 2011, weather permitting."
La Poposa is a high sulphidation gold-copper system located in
the Cordellera Frontal of Argentina in San Juan province. The
project is located in the The El Indio-Pascua/Lama metallogenic
belt which hosts several multi-million ounces gold deposits such as
Veladero, and is located approximately 50 km to the
south-south-east of Malbex Resources' Del Carmen project. La Poposa
was explored in the 1990's by a number of companies looking for a
large disseminated gold system. Extensive low grade gold was
discovered in a massive silica altered rhyolite. Drilling by
previous groups was limited and very shallow in nature. The size of
the alteration system is very large (approximately 6 km by 3 km)
and Terreno's geologists think that the project has not been
adequately explored and has potential for both structurally
controlled mineralisation at relatively shallow depths and a
porphyry style copper gold system at greater depth.
The Qualified Person for Terreno's projects is Mr. Peter
Mullens, who is a member of the Australian Institute of Mining and
Metallurgy. Mr. Mullens has reviewed and approved the technical
content of this release.
Chemical analysis was completed by ALS Chemex Laboratories using
Au-ICP22 for gold and ME-MS41 for other elements.
About Terreno Resources
Terreno, meaning "of the earth" in Spanish, represents the
Company's focus on natural resource opportunity development in
South America. Terreno has option agreements on three exploration
projects in Argentina; La Poposa (formerly referred to as Amarillo)
in San Juan, Socompa and Trigal in Salta. All three projects boast
significant alteration systems and have the potential for copper,
gold and silver mineralization. For more information, please visit
