Zena Mining Corp. ("Zena" or the "Company") (TSX VENTURE:ZCC) is pleased to
announce that it has completed its 2010 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,
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.


Zena explored the "B" zone deposit in July 2010 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. This zone is open to the north. Within the Main zone, seven
samples ranged from 75% to 92% Barite (BaSO4). Specific gravity varied from 3.68
to 4.52, averaging 4.15. Analyses were done by ALS Chemex Laboratory in North
Vancouver, a certified laboratory. A minimum specific gravity of 4.10 is
required for Barite used as a weighting medium for drilling mud. 


The samples were analyzed for Barite, for specific gravity and for 30+ elements
using normal Induction Coupled Plasma (ICP) techniques. ICP analysis is a
standard labororatory method widely used for determination of trace and major
elements. Silica (SiO2) is the chief contaminant, averaging about 16% along with
small amounts of calcium carbonate and phosphate which do not appreciably affect
the specific gravity. There are only small amounts of base metals, copper, lead
and zinc, and these are not significant in terms of commercial Barite.


During the mapping program a number of new Barite lenses were found north of the
stripped area. The stripping was done on a Barite zone known as the "B" or
hilltop zone. Total cost of the 2010 program was approximately $60,000.


The property has at present three known zones with Barite mineralization, known
as A, B and C zones. Past exploration including trenching and drilling at the
"A" zone has established a Barite deposit with grades above or near the specific
gravity threshold of 4.10. A NI 43-101 measured resource of 5,800 tonnes with
specific gravity of 4.25 and an inferred resource of 10,000 tonnes averaging
specific gravity of 3.93 was estimated for the "A" zone by Godfrey Walton P.Geo.
(2003).


According to a technical Report completed by B.J. Price Geological Consultants
Inc. in January 2011, there is a reasonable chance that further exploration may
develop an economic tonnage and grade of Barite; this possibility cannot be
quantified and can only be verified by further work. 


The Company's 2011 planned exploration program, with a cost budget to be
approximately the same as the 2010 program, includes the stripping of the
northern limits of the Barite lenses in the "B" zone, with the possibility of
producing a 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 supervised the stripping
and sampling program and has completed the Technical Report.
