BOWMORE Exploration Ltd. (TSX VENTURE:BOW) ("Bowmore" or "the Company") is
pleased pleased to announce the results from its summer drilling campaign on the
Chivas property, located in Sonora province, Mexico. The drilling outlined a new
hydrothermal mineralized breccia structure at Mesa Blanca, and also extended
laterally and at depth the Piedra Rodante high grade low-sulfidation structure
discovered by Amex's Mexican subsidiary 'Minerales X-Ore' in 2006.


This first phase of drilling consisted of 7 drill holes totaling 2065.4 meters
to test portions of the epithermal system discovered in 2011 (see press Release
April 13, 2011) and to test the high grade gold-silver veins from the Piedra
Rodante zone.


Highlights include:

High grade gold-silver veins where cut at the Piedra Rodante zone in holes:



--  Hole NS-12-07
    Individual sections intersected, included 12.85 g/t Au and 444.0 g/t Ag
    over 1.5 meters.

--  Hole NS-12-06
    Individual sections intersected, included, 8.42 g/t Au and 85.9 g/t Ag
    over 3 meters and ;

--  Hole NS-12-05
    Individual sections intersected included 5.83 g/t Au and 147.0 g/t Ag
    over 1.4 meters;



All of these intersects are contained within much larger, lower grade
breccia-type structures that returned: 0.62 g/t Au and 32.5 g/t Ag over 72.00
meters in hole NS-12-07; 1.11 g/t Au and 17.4 g/t Ag over 28.7 meters in hole
#NS-12-06; 0.48 g/t Au and 44.6 g/t Ag over 62.0 meters in hole #NS-12-05 (see
table #1).

Paul A. Dumas President and CEO of Bowmore and Jacques Trottier President and
CEO of Amex commented: "We are very excited with the results of this first phase
drill program, with very limited drilling, we have successfully demonstrated the
lateral and at depth extensions of the Piedra Rodante zone and, second, made a
new discovery at Mesa Blanca. Even though gold and silver values at Mesa Blanca
are thus far low, they are good indicators that we are above a much larger
system, and possibly be connected with the Piedra Rodante to the north. Only
deeper drilling of this new hydrothermal low-sulfidation structure will
demonstrate its economic potential. Furthermore we still have not tested the
"Mesa" and "Cerro Rojo" zones to the NNW of the Piedra Rodante zone whereas
several indicators of the epithermal system are still present."


The structure of the Piedra Rodante zone, where the mineralization is emplaced
in a N005W fault with 60-62 degrees dip toward the East, is known in outcrops
and in various drill holes over a strike length of about 1,000 meters and to a
depth of 240 meters, and is still open below this level. The mineralized
structure presents a low grade envelope, 10 to 20 m wide, of greater than 1 g/t
Au and greater than 100 g/t Ag that include 1.5 to 6 meter wide intervals with
grades greater than 8 g/t Au and greater than 350 g/t Ag. The paragenesis of the
mineralization includes an early stage of marcasite-pyrite with low silica
content followed by a pulse of hydrothermal breccia. This breccia presents
clasts of the volcanic host rock, and sulfide fragments of the early sulphide
event cemented by a hydrothermal matrix composed by bands of chalcedonic silica,
and py-marcasite-arsenopyrite with colloform - crustiform texture. The total
content of sulfides doesn't exceed 5% volume. The silicate-alteration-epithermal
minerals observed within the best-mineralized zone include illite-sericite,
illite-smectite (the two micas assemblage), probably white fine-grained
adularia, and carbonate minerals that had been leached. 


Down dip, the vein of Piedra Rodante is marked by a low grade mineralized
envelop that surrounds the high-grade vein-breccia zone. Within the low grade
mineralized envelop there is a high grade zone that continues within the 240
meter known vertical section, including 3 to 6 m intervals with Au equivalent
values between 5.8 g/t and 9.94 g/t. The best-mineralized interval was
intersected in the deepest drill hole with 6 m of 9.94 g/t Au eq., including
1.5m of 20.3 g/t Au eq. The Ag: Au ratios do not present a clear vertical
zoning, with values varying between 40 and 140. (A ratio of 60 has been used to
convert Ag into Au equivalent values)


The other zone of interest (as described in the Press Release dated May 17th
2012) is called 'Mesa Blanca', where high resistivity anomalies at the
sub-surface were found, indicating the presence of anomalous gold and silica
associated with disseminated sulphides. It also corresponded to previous surface
sampling and identification of high silicification and a large area of anomalous
buddingtonite from the TerraSpec sampling program done in early 2011. 


Results from the two holes drilled to test this target (NS-12-03 and NS-12-04),
are separated by about 550 meters and are quite similar. This target is located
at about 1000 meters SSE of the Piedra Rodante zone. Both have cut a brecciated
silicified zone that is similar to the breccia observed in outcrops and contain
clasts of the volcanic host rock cemented by fine-grained silica red matrix.
Gold grades greater than 1g/t are associated with the injection of py-marcasite
and chalcedonic silica within the breccia. Drill hole NS-12-03 was drilled in
this area and intercepted a structure with 20.5 meters @ 0.1 g/t Au, 0.5g/t Ag,
204 ppm As and 15 ppm Sb at around 110 m from the current surface, and drill
hole # NS-12-04 intersected a similar structure with 18.75 meters @ 0.07 g/t Au,
1.3 g/t Ag, 275 ppm As and 13 ppm Sb at about 200 meters below the current
surface. 


The Chivas Property is composed of 2 exploration titles covering over 24,841
hectares and is located within the Sierra Madre Occidental gold belt ("SMO").
The SMO is known to host reserves of more than 40 Million ounces of gold and 2
Billion ounces of silver. The Chivas property, optioned from Amex Exploration
Inc. (AMX: TSX-V, "Amex") is 15 kilometers to the west of the Dolores Mine
previously owned by Minfinders Corporation Ltd. and now Pan American silver
Corp. The earn-in option provides Bowmore the right to acquire up to 70%
interest in the property (see news release dated April 8, 2010. 


Amex and Bowmore managements are very enthusiastic about the results of this
first drilling campaign on the property located in the prolific Sierra Madre
gold belt. 


Bowmore follows strict QA-QC protocol measures in keeping with industry
standards and regulatory reporting requirements. All drill cores was processed
using descriptive logging and systematic sampling for analysis. NQ core samples
were cut in half, with one half delivered to a commercial laboratory and the
other half retained for future reference. Duplicates, blanks and standards were
inserted into the sample sequence. Lost core within mineralized intersections
(generally less than 1%) were incorporated as blank intervals. All samples were
prepared and analyzed at the facilities of ALS Chemex Hermosillo, Mexico and
pulps sent to ALS Chemex Vancouver. Gold content was first analyzed utilizing
standard fire assay fusion of a 50 gram charge, followed by Atomic Absorption
Spectroscopy (Au 50g FA AA finish). For those samples that yielded assays
greater than 10 ppm Au (10 g/t Au), the samples were assayed again utilizing
standard fire assay fusion, followed by gravimetric analysis (Au 50g FA-GRAV
finish). All other elements, including silver, were analyzed utilizing
Inductively Coupled Plasma - Atomic Emission Spectroscopy (35 Element Aqua Regia
ICP AES) methods, on a prepared sample digested with aqua regia. For those
samples that yielded assays greater than 100 ppm Ag (100 g/t Ag), the samples
were assayed again by the default over limit method Ag Ore grade Ag - Aqua
Regia. The reader is directed to ALS Chemex website for more details:
