Rio Cristal Resources Corporation (TSX VENTURE:RCZ)(BVL:RCZ) ("Rio Cristal" or
the "Company") today announced the first independent National Instrument
43-101-compliant resource estimate for its Cristal zinc oxide deposit at its
Bongara Property in Northern Peru. The effective date of the resource estimate
is January 31, 2012.


Thomas Findley, President and CEO of Rio Cristal, said, "I am pleased to
announce that we have an initial measured and indicated resource at our Cristal
Project of 1,273,000 tonnes of zinc oxides grading 7.55% zinc. The resource,
based on 9,139 meters of drilling, confirms our belief that our concessions have
outstanding potential for significant zinc discoveries. The Company controls
18,413 hectares at Bongara and we have only drilled approximately 3% of that
area."


The resource estimate at the Cristal deposit was reviewed and approved by John
A. Brophy, an independent Qualified Person as defined by National Instrument
43-101.

The work done by the Company in 2011 at Bongara included multi-media sampling
(328 rocks, 482 soils, 260 stream sediments) as well as the drilling of 57 HQ
holes totaling 4,759 meters. This work expands the multi-media sampling (445
rocks, 389 soils, 79 stream sediments) and drilling of 40 HQ holes totaling
4,380 meters done by the Company in 2007-2008 as described in a 43-101 report
titled "Rio Cristal Resources Corp. - Charlotte Bongara Zinc Project NI 43-101
Technical Report" dated February 1, 2010 and filed on Sedar on February 10,
2010.


More than 80% of the soil and rock sampling done in 2008 and 2011 was confined
to a +/-3 square-km area encompassing the Cristal Project including an area
known as Charlita. Anomalies in rock (typically greater than 5,000 ppm and up to
41.6% Zn) and soil (typically greater than 1,000 ppm and up to 28.5% Zn) were
used as the criteria for spotting drill holes. 


With the exception of two scout holes drilled in 2011 from one platform at the
San Jose Project, about 12 km southwest of Cristal, drilling was entirely
confined to Cristal and Charlita, with about 75% drilled at Cristal. Both zones
are underlain by dolomitized limestone of the Condorsinga Formation and are
considered to be Mississippi-Valley-Type deposits. So far, drilling has
identified relatively low-grade zinc mineralization at the Charlita Project (2%
to 6% zinc across intervals of up to 6.9 meters in 6 of 15 holes). At the
Cristal Project, significant mineralization (up to 26% Zn across 23 meters) was
intersected in about half of the holes drilled. 


The initial mineral resource was calculated by an independent specialist (Dr.
Miguel Zulueta Torres) using DataMine software and working in concert with the
Company's geological team to create three-dimensional solids (or enveloping
surfaces) for the purpose of determining a mineral resource for the Cristal
Project including Charlita. Mr. Brophy reviewed and verified the calculations of
Dr. Zulueta. 


Drilling in 2011 was done by Energold Drilling Peru SAC. A total of 57 holes
were completed on 21 platforms, and 4,759 meters of HQ core (diameter 6.35 cm)
were retrieved. Most of the drilling (2,548.45 m) was concentrated at the
Cristal Project (40 holes on 15 platforms) with the objectives of expanding the
mineralization drilled in 2008 and of securing enough information with infill
drill holes to calculate tonnage and grade in the mineral resource category.
Fifteen scout holes (793.8 m) on six platforms were drilled at the Charlita
Project. 


While the two holes at the San Jose Project did not reach the zinc sulfide
targets in the Chambara Formation, extensive zinc sulfide anomalies were
intersected. For example, a vertical hole (720 meters) intersected 95 meters
with a weighted average grade of 0.17% zinc at and below the Aramachay -
Chambara contact. Similar grades were found in the inclined hole (697 meters),
which culminated in limestone grading 0.38% zinc; the highest of 254 assays
taken from the two drill holes. The Company expects to return to the San Jose
zone in 2012 to continue deeper drilling with a larger drill unit, especially at
locations corresponding to the deepest stratigraphic levels.


In total, 1,584 core samples (excluding 175 blanks, standards and duplicates)
were sent to Inspectorate Services Peru SAC (Inspectorate) in Lima for analysis.
The average sample interval was 1.94 meters, and the aggregate length of all the
core samples was 4,477.65 meters. In general, core recovery was good (greater
than 95%), although occasionally open spaces were encountered (karsts).


All 2011 samples were prepared and analyzed by Inspectorate. The preparation
procedure comprised drying samples followed by coarse crushing in a jaw crusher
to 70% passing -2 mm, followed by pulverization of a 250 g split in a ring and
puck mill to 85% passing 75 um. The analytical procedure at Inspectorate
included use of atomic absorption spectroscopy to determine zinc and lead using
the Zn-AA46 and Pb-AA46 packages, a 35-element ICP-AES analysis with aqua-regia
digestion, and a trace mercury analysis from cold vapor with an
atomic-absorption finish. 


Inspectorate is registered in Peru as an ISO 9001-2000-certified Company and
does not have any special arrangement with Rio Cristal Resources Corp other than
that of a client-provider relationship.


An independent National Instrument 43-101 technical report documenting the
mineral resource estimate will be filed on SEDAR within 45 days.
