J.A.G. MINES LTD (JAG) (TSX VENTURE:JML) and its subsidiary OLITRA Inc. announce
that the discovery of natural gas by companies Ressources et Energie Squatex and
Petrolympic has been very well received. JAG wishes to publish an update
concerning the progress of its exploration work in the Bas-Saint-Laurent region,
particularly on its vast Temiscouata property that extends from Riviere Bleue,
near the border with Maine, up to the Rimouski reserve, an area of 89,147
hectares (222,868 acres).


Following a thorough exploration campaign lead by geologist Marc R. Lafleche
from the Institut national de la recherche scientifique (INRS), JAG has
identified on the Temiscouata property three highly abnormal domains of soil
gas, characterized by very high concentrations of methane, ethane, propane and
butane, and molecular ratios revealing the presence of thermogenic hydrocarbon
sources (within rock), probably hosted in the Ordovician and Silurian
sedimentary rocks of the region. These units are overlain by the Devonian shale
of Temiscouata which forms an impervious barrier. Numerous showings of variably
dolomitized reefal limestone, as well as sandstones similar to Gaspe sandstones
(ZEC Owen sector), occur and will be investigated by JAG in 2014. Consequently,
the Company intends to complete a number of core drill holes similar to those of
the mining industry in view of documenting the presence of reservoirs and locate
host rock units responsible for hydrocarbon generation. From west to east,
priority targets to be investigated through geophysics and drilling are the
St-Eusebe and Lake Ango in ZEC Owen sectors, and the vicinity of the wildlife
reserve of Rimouski bordering the Squatex-Petrolympic property, host of the
conventional natural gas discovery in Bas-Saint-Laurent.


As part of its funded works for gas and oil exploration, JAG should be able to
present by June 2014 the initial results of a large-scale pedogeochemical and
radiometric study conducted on the whole area of its Pohenegamook property. Said
property is located in Bas-Saint-Laurent, west of the Temiscouata property, and
encompasses an area of 133,459 hectares (333,648 acres). It is important to note
that the Pohenegamook property is in close proximity to the Parke wells site,
whose potential for natural gas storage is being evaluated by Intragaz.


In other respects, JAG is pursuing its gold exploration activities on its
Belleterre property in Temiscamingue. From October to November 2013 and in March
2014, JAG had a high- resolution gravimetric survey performed in order to refine
geometry and relative importance of the main auriferous and intrusive structures
located west of the old Belleterre mine. The gravimetric data are added to the
new high-resolution audio- magnetotelluric sections executed on the Aubelle,
Castor, Village and Boudrias prospects.


From September to November 2013, a team of geologists proceeded to a study and
channel sampling from the Boudrias and Village showings and prospected new
showings (JAG-1, JAG-2, JAG-3, JAG-4 and JAG-5) that reveal the presence of
polymetallic porphyritic mineralisation located in the eastern part of the
property. A wide-ranging lithogeochemical study of volcanic, sedimentary and
intrusive rocks, as well as iron and chert formations, was completed during the
2013-14 winter. This study strongly suggests the presence of high-temperature
volcanogenic hydrothermalism during the orogeny of the Belleterre volcanic
rocks. This conclusion implies a strong potential for the discovery of
volcanogenic polymetallic massive sulphides.


A mineragraphic study is ongoing at INRS in order to characterize gold
distribution in the main zones of auriferous mineralisation on the property.
This study aims at providing data on granulometry and degree of gold liberation
with the objective of optimizing metallurgical work to be performed on bulk
samples that will be gathered in early summer and early fall of 2014, and
improving resource estimation models.


The geological portion of this press release was reviewed by Marc
Richer-Lafleche, geologist and professor at the Institut de la Recherche
Scientifique de Quebec, qualified person as required by NI 43-101, and approved
its publication.
