Terreno Resources Corp. (TSX VENTURE:TNO) ("Terreno" or the "Company") is
pleased to announce that it has signed a contract with Falcon Drilling
Argentina, based in Salta, to commence a minimum 3,000 metres drill program
commencing in mid-February 2012. The first 1,000 metres of drilling will test
near surface epithermal gold targets on the company's Poposa, high sulphidation,
gold-copper project in San Juan province. Following completion of this program,
the drill will move to the Socompa porphyry copper-gold-molybdenum project
located in Salta province where it will complete a minimum of 2,000 metres
testing coincident magnetic and surface anomalies.


"We are looking forward to commencing our first drill campaigns at the Poposa
and Socompa projects. We have completed significant ground and geophysical
programs which give us high confidence for success," commented Peter Mullens, VP
Exploration. "Recent programs at nearby projects, including those owned by
Lumina Copper Corp., Malbex Resources Inc. and Regulus Resources Inc./Pachamama
Resources Ltd., have made new discoveries and expanded existing resources
providing indications that both of these projects are located in highly
prospective and prolific trends." 


Poposa:

The Poposa project is a high sulphidation gold-copper system located in the
Cordillera Frontal of Argentina in San Juan province. The project is located in
the El Indio-Pascua/Lama metallogenic belt which hosts several multi-million
ounces gold deposits such as Veladero, and is approximately 50 km to the
south-south-east of Malbex Resources' Del Carmen project (See figure 1 for a
regional location map: http://media3.marketwire.com/docs/tno_f1_118.pdf).


Work completed in the previous field season included 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. Revised
geological modeling combined with the results of geophysical surveys has
identified two distinct exploration targets:




1.  Near surface epithermal gold in three district areas (Colorado, Amarillo
    and Morro). These areas are located within several kilometres of one
    another and have mineralization at surface (identified through
    trenching), strong resistivity over significant strike and depth
    (identified through the Titan 24 survey) and remain relatively untested.
2.  Deep porphyry in two areas (Negro and DDH-13). The target is at depth
    along the unconformity with the basement and still remains to be tested.
    Geophysical surveys identified moderate chargeability/resistivity
    anomalies with coincident large aeromagnetic anomalies as potential
    porphyry ore shell locations in these areas.



The Company's geologists are now in the field finalizing the drill locations for
this exploration program of up to 1,000 metres (5 holes) which will focus on
testing the near surface targets at the Amarillo and Morro target areas.
Drilling is expected to commence on or around February 15th 2011 (see figure 2
for a drill plan map: http://media3.marketwire.com/docs/tno_f2_118.pdf).


Socompa:

The Socompa project is a copper-gold porphyry target located in western Salta
province approximately 70 kms from BHP Billiton's Escondida mine, 40kms from
Lumina Copper's Taca Taca porphyry copper project and 67 kms from the Rio Grande
project currently a joint venture between Regulus Resources and Pachamama
Resources. The project hosts a large, 20km2 zone of argillic alteration with
some sectors displaying pervasive silicification. Several producing Cu, Cu-Mo
and Cu-Au-Mo mines are located in the region (Escondida, Saldivar, Chimborazo)
within the same crustal corridor as the project (see figure 3 for a regional
location map: http://media3.marketwire.com/docs/tno_f3_118.pdf).


Last field season Terreno completed geological mapping, ground magnetics and
surface sampling from rock chips and trenches. The company has identified three
anomalous zones based on widespread surface copper, gold and molybdenum:




1.  North Copper-Gold Anomaly, high copper content, surface samples between
    800 and 7000 ppm Cu with gold between 0.3 g/t and 0.5 g/t in structures
    with advanced argillic alteration. 
2.  Central Gold-Molybdenum-Copper Anomaly, 21 gold samples above 0.1 ppm,
    22 copper samples values above 500 ppm and 12 moly samples above 20 ppm
    over and stockwork outcrop measuring 400 metres by 150 metres. 
3.  Central Molybdenum Anomaly, systematic trench sampling returned 250
    metres averaging 80 ppm Mo from 2 m samples.



A follow-up infill mag survey was completed in Q4 2011. The initial drill
program of up to 2,000 metres (5 holes) will focus on testing the bulls-eye
magnetic anomaly identified in the survey, which lies beneath a scree cover
immediately to the west of the Central Gold-Molybdenum-Copper Anomaly. Drilling
is expected to commence in late March, once the Poposa program is completed and
the rig has been remobilized (see figure 4 for a drill plan map:
http://media3.marketwire.com/docs/tno_f4_118.pdf).


Trigal:

A field program has recently been completed at the Trigal high sulphidation
silver-gold target located in north-western Salta province, immediately adjacent
and to the north east of the El Quevar project owned by Golden Minerals. The
project covers an area of acid sulphate alteration (silica alunite) with the
main exploration target being high grade structurally controlled silver
mineralization. The work program included stream sediment, talus and chip
sampling as well as mapping the alteration. The samples have been sent to the
assay laboratory for evaluation.

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
