Zena Mining Corp. (TSX VENTURE:ZCC) ("Zena" or the "Company") is pleased to
announce that it has completed its 2012 exploration program on its Lapin Barite
property situated near Rock Creek, B.C. The Company owns 100% of the rights to
the Industrial Minerals subject to a 10% net profits interest and royalty and
other payments based on production to the original underlying vendors.


Barite (Barium sulphate - BaSO4) the primary industrial mineral on this
property, is a major component and the weighting agent used in drilling mud for
the oil and gas industry's exploration and developmental drilling programs. In
2004, Zena obtained a permit for exploration and test mining a small bulk
sample.


In 2010, Zena explored the "B" zone deposit by excavator stripping, mapping, and
diamond sawing representative samples. Stripping exposed an area roughly 40 by
20 meters which contains at least five zones of Barite, of which the most
important is the Main zone, exposed over a strike length of 20 meters and up to
10 meters wide.


In September 2011, additional areas in the "B" zone were stripped, and argillic
sediments were removed from the east wall of the Main zone. An excavator with a
rock-breaker was used to expose the barite along its length, and about 200
tonnes of barite was set aside from which 20 tonnes was mined and trucked to a
storage site in Rock Creek B.C. From the "B" zone, 26 barite samples each from
1-5 kg in size (averaging 3 kg) were collected from four separate areas and
shipped to ALS Minerals Laboratory (ISO 17025 accredited) in North Vancouver,
where Specific Gravity measurements were completed. The twenty-six samples from
the Main Zone had specific gravity ranging from 3.63 to 4.41, with a weighted
average of 4.12.


A minimum specific gravity of 4.10 is required for Barite used as a weighting
medium for drilling mud.


In July 2012, a small work program was completed on the "B" zone, stripping an
additional area approximately 20 meters northward from the 2011 work. Additional
barite was broken out using an excavator and set aside for sampling and testing.
Approximately 500 tonnes of barite is now piled at the side of the stripped area
and is available for testing.


In October 2012, the barite was randomly sampled along the length of the mined
material with 3 samples totalling approximately 25 kg. The weighted average
specific gravity measured by ALS Canada Ltd. Laboratory was 3.83. Individual
samples tested ranged from specific gravity of 2.67 to 4.09.


The property has at present three known zones with Barite mineralization, known
as "A", "B" and "C" zones.


The Company's 2013 planned exploration program, subject to renewal of the
exploration and test mining permit from the Mines Inspection Branch, is
recommended to be approximately the same as the 2012 program, with a cost budget
to be approximately the same as the 2012 program. The 2013 program will include
additional stripping of the northern limits of the Barite lenses in the "B"
zone, with the goal of producing a larger test sample. The Company may also
include in the exploration program further review of the "A" zone.


This press release has been reviewed by Barry J. Price, M.Sc., P.Geo., an
independent consultant based in Vancouver BC. Mr. Price reviewed the 2012
stripping and sampled the test-mined material.
