Dia Bras Reports Drilling and Sampling Results at Its La India Area, Cusi Property, Chihuahua, Mexico

March 13, 2012

TSX Venture Exchange – DIB

TORONTO, March 13, 2012 /PRNewswire/ – Dia Bras Exploration Inc. (TSXV: DIB) (BVLAC: DIB) (“Dia Bras”) (the “Company”) is pleased to announce results of drilling
and sampling of veins at its La India project in the Cusi property,
Chihuahua, Mexico.  Drilling has been conducted on the Durana and
Saturno veins (see Figure 1: Map of the La India Area) and the San Jose vein has been sampled along its strike length where
the vein is exposed in old pits and stopes.

The La India area contains many high-grade silver veins of considerable
strike length that were intensively mined by historical workers in
areas where the veins are structurally complex (see Figure 1: Map of the La India Area).  These complexities are the result of flexures of the veins, splays
off the main veins, and vein intersections.  Dia Bras first conducted
drilling programs in this area in 2006.  The potential of this area is
indicated by the impressive intersection in drill hole DC06B012 that
yielded 35,442 g/t Ag over 0.4 m within a 7.0 m section that assayed
2,257 g/t Ag (see press release of October 3, 2006).

An area of similar structural complexity occurs in the vicinity of La
Abundancia and San Jose shafts where 20 de Noviembre, La Candelaria and
San Jose veins intersect and exhibit flexures.  In addition, the
Saturno and Durana veins extend to the 20(th) de Noviembre vein, which creates additional complexity.  Sampling by
Dia Bras geologists (see below) of the San Jose vein yielded high
grades of silver in highly-oxidized outcrops, old prospect pits and
shallow open stopes.

The historic miners concentrated on veins containing very high grades of
silver (>1,000 g/t) due to the mining methods and operating costs of
the time (pre-20(th) Century) in what was then a remote area.  Their results from pitting
and stoping on the San Jose vein apparently discouraged any further
work because no mining was done from it.

The grades of silver returned from Dia Bras’ sampling indicate the veins
contain potentially-economic grades of silver for a modern operation,
especially in the un-oxidized portions at depth.

Dia Bras intends to continue work in the La India area to develop and
mine these silver-rich veins as part of the Company’s strategy of
becoming a significant producer of silver.

The following table shows assay results from drill samples at the La
India area:

The San Jose vein (see Figure 2: Sample Location Map of the San Jose Vein) is within an area identified by the Company’s geologists as being a
very favorable exploration area, based on the multiple vein
intersections there.  The San Jose vein was sampled by historic workers
who dug shallow pits, shallow open stopes and a shallow shaft.  The
vein is strongly oxidized in these workings.  Silver grades were
apparently too low to attract development at that time but sampling of
the old pits and dump material at the San Jose shaft by Dia Bras
demonstrates that the grades are potentially economic with modern
mining methods, as indicated in the tables below.

The following table shows assay results from samples collected from the
highly-oxidized dump at the San Jose shaft.  Nineteen samples were
collected that average 113.6 g/t silver.

The Company intends to continue drilling and underground sampling in the
La India area with the objective of developing the area for another
mining area. The La India area will become a third area of mining in
the Cusi property, together with the Santa Eduwiges and Promontorio
areas.

Method of Analysis
Samples were prepared at the ALS Chemex lab facility in Chihuahua,
Mexico, and analyzed by ICP and AA methods at their facilities in
Vancouver, Canada. Diamond drill samples sent for analysis consisted of
half NQ-size and BQ-size diamond core split on site, prepared by the
ALS Chemex sample preparation laboratory in Chihuahua, Mexico, and
assayed for Au by 50 g fire assay with AA finish, and for Ag by AA on
50 g split sample at the ALS Chemex North Vancouver Laboratory. Assays
for Pb, Zn and Cu are analyzed by Induction Coupled Plasma (ICP) at ALS
Chemex.
