Tintina Resources Inc. ("Tintina" or the "Company")
(TSX-VENTURE:TAU)(OTCQX:TINTF) is pleased to announce it has received assay
results for fifteen (15) new drill holes from the company's flagship Black Butte
Copper Project, located in central Montana, USA (see table 1). These in-fill
drill holes completed in late 2012 in the Lowry Deposit Middle Zone together
with earlier drilling results will form the basis for a new Lowry Deposit Middle
Zone resource estimate, expected in Q2 of 2013.
Highlights of the 2012 in-fill drill program from the Lowry Deposit - Middle
Zone (LD - MZ):
-- Drill hole SC12-152 intersected 38.40 meters grading 2.66% Copper (Cu),
0.09% Cobalt (Co), and 12.5 g/tonne Silver (Ag)
-- Drill hole SC12-163 intersected 16.90 meters grading 2.85% Copper (Cu),
0.08% Cobalt (Co), and 16.6 g/tonne Silver (Ag)
-- Drill hole SC12-164 intersected 38.13 meters grading 2.83% Copper (Cu),
0.08% Cobalt (Co), 16.7 g/tonne Silver (Ag)
-- Drill hole SC12-168 intersected 23.66 meters grading 5.45% Copper (Cu),
0.11% Co, and 20.9 g/tonne Silver (Ag).
The results from the four (4) 2012 drill holes highlighted above are among
results from fifteen (15) new drill holes which will help provide the basis for
a forthcoming Lowry Deposit Middle Zone (LD-MZ) resource estimate which is
scheduled to be completed later in 2013. Two (2) holes, SC12-161 and SC12-163,
continued to depth to test the Lowry Deposit Lower Zone (LD-LZ) and six (6)
additional holes also produced good grade but thin intersections from the Lowry
Deposit Upper Zone (LD-UZ), and these results are also tabled below in Table 1.
Jerry Zieg, Vice President of Exploration said: "We are very pleased to continue
to report thick, high grade copper intersections from the Black Butte Copper
project. The Lowry Middle Zone results will form the basis for a new resource
estimate for the Lowry deposit which should become a substantial addition to our
Measured and Indicated Resource inventory. We will then have the opportunity to
incorporate the updated drill defined resources in a pre-feasibility or
feasibility study currently being contemplated by the Company."

2012 achievements and 2013 plans
The Company completed a Preliminary Economic Assessment ("PEA") only on the
Johnny Lee deposit Indicated and Inferred Resource during 2012 (see news release
dated September 4, 2012) and has since upgraded the Johnny Lee deposit to a
Measured and Indicated resource containing 910 million pounds of copper at a
3.57% copper grade, with an additional Inferred resource of 94 million pounds of
copper at a 2.91% copper grade (see news release dated November 13, 2012). The
Company has also completed an infill drilling program on the Lowry deposit,
which currently has an Inferred Resource of 294 million pounds of copper at a
grade of 2.6% (see news release dated November 1, 2012). The Company expects the
recently completed drilling will allow an upgrade of the Lowry deposit to an
Indicated resource. The Company continues engineering, geotechnical,
hydrological, metallurgical and baseline environmental studies in preparation
for a revised PEA incorporating a higher throughput scenario, which may include
the Lowry deposit. The revised PEA is expected in Q2, 2013. Finally, the Company
plans to commission a pre-Feasibility Study ("PFS") or Feasibility Study ("FS")
after completion of the revised PEA. The Company expects to complete the PFS or
FS by Q3, 2014.
About the Black Butte Copper Project
Geologists with Cominco American Inc. and joint venture partners Utah
International and BHP discovered the deposits contained in the Black Butte
Copper project during exploration programs in the 1980's. In 1993, after
completing 60,775 meters drilled in the district, Cominco turned the property
back over to the ranch owners and the copper deposits lay dormant until 2010
when members of the original discovery team now with Tintina re-established
contact with the property owners. In May of 2010 Tintina entered into mining
leases on over 5,000 acres (2,023.4 hectares) of private ranch lands which
contain all currently identified resources at Black Butte Copper. Present land
holdings consist of 7,684.3 acres (3,109.7 hectares) of private ranch lands and
239 Federal mining claims totaling 4,541 acres (1,837.7 hectares). Tintina has
completed 54,447 meters of drilling since September of 2010. At least five
additional copper mineralized zones have been identified in the resource area
and may contain additional resource. Tintina has completed a positive
Preliminary Economic Assessment (PEA) (see news release dated September 4,
2012). The Company expects the completion of an expanded PEA in Q2 2013 and
expects approval of their amendment for an exploration decline in Q2 2013. The
Company is targeting the granting of a Mine Operating Permit in 2015 and copper
production in 2016.
The Johnny Lee Deposit lies 3.2 km (2 miles) west of U.S. Highway 89, and is
comprised of the Johnny Lee Deposit Upper Zone (JL-UZ) and the Johnny Lee
Deposit Lower Zone (JL-LZ). Both zones consist of tabular layers of
copper-cobalt-silver mineralization as bands of massive chalcopyrite within
fine-grained massive pyritic sulfide layers hosted by shale and conglomerate.
The JL-UZ deposit lies at depths ranging from 30 to 210 meters below the surface
and is up to 29.17 meters thick. The JL-LZ lies at depths ranging from 340 to
500 meters below surface and is up to 22.30 meters thick. Portions of both the
Upper and Lower Zones are faulted away and have yet to be located. Additional
sulfide zones lie above the JL-UZ and contain variable concentrations of zinc
and copper. The Johnny Lee deposit contains an undiluted Measured and Indicated
resource of 910 million pounds of copper at a copper grade of 3.57%. This
includes the Johnny Lee Lower Zone, which contains an undiluted Indicated
Resource of 337 million pounds of copper at a grade of 6.4% copper. The Johnny
Lee deposit also contains an undiluted Inferred Resource of 94 million pounds of
copper at a copper grade of 2.91% copper.
The Lowry Deposit (Fig. 2) lies 1.2 kilometers (0.75 miles) west of U.S. Highway
89 and consists of at least five copper mineralized zones. Of these, the Lowry
Middle Zone is a tabular layer of copper-cobalt-silver mineralization reaching
up to 79 meters thick with high concentrations of chalcopyrite (copper-iron
sulfide) concentrated within fragmental, silicified and dolomitized shale and
carbonate. Individual drill holes contain as much as 2.8% Cu over 50.9 meters
drilled thickness. The deposit dips gently to the south, lies at depths ranging
from 265 to 718.5 meters below surface, and measures 600 meters by 300 meters in
plan. The northeast trending Rose fault down drops the southeast portion of the
zone, where two holes extend the zone by about 100 meters. These holes have not
been offset further east or south. The Lowry Middle Zone contains an undiluted
Inferred Resource of 294 million pounds of copper at a copper grade of 2.6%
copper and a new resource estimate based on recent infill drilling is expected
in Q2, 2013. More drilling is required to bring any of the other copper
mineralized zones to the Inferred Resource category.
These deposits are amenable to underground mining, an approach consistent with
the desires of the landowners and community. Community and regional support for
the project is high due to the strong desire for jobs in this economically
challenged rural Montana area. Permitting activities are ongoing using highly
knowledgeable Montana-based consulting groups together with the in-house team.
Base-line and other key studies for permitting are carried out in close
cooperation with the Montana Department of Environmental Quality to ensure high
quality and complete permit applications.

Notes:
1. Mineral Resources have been classified according to the "CIM Standards
on Mineral Resources and Reserves: Definitions and Guidelines" (December
2005). The preliminary economic assessment contained herein is
preliminary in nature and includes inferred Mineral Resources that are
considered too speculative geologically to have the economic
considerations applied to them that would enable them to be categorized
as Mineral Reserves and there is no certainty that the preliminary
economic assessment will be realized.
2. It cannot be assumed that all or any part of an Inferred Resource will
be upgraded to an Indicated Resource, or that an Indicated Mineral
Resource will be upgraded to a Measured Resource, as a result of
continued exploration. Mineral Resources are not Mineral Reserves and do
not have demonstrated economic viability. There is no certainty that all
or any part of the Mineral Resources will be converted into Mineral
Reserves. Mineral Resources are global in situ totals.
3. For the Johnny Lee Upper Zone, cutoff grade calculation is based on
assumed metal prices of $2.75/lb for copper and an 81% recovery. A
mining cost of $US $59.00/tonne, processing costs of US $16.00/Tonne,
and G&A costs of U.S. $5.00/tonne were assumed to form the basis for the
resource cut-off determination. For the Johnny Lee Lower Zone, cutoff
grade calculation is based on an assumed metal price of $2.75/lb. for
copper and an 84% Cu recovery. A mining cost of US $50/tonne, processing
costs of US $16/tonne, G&A costs of US $5.00/tonne, and refining costs
of US $5.53/tonne, were assumed to form the basis for the resource cut-
off determination. Note: these costs differ from those used for the cash
flow model in the PEA.
4. Mineral resource tonnage and contained metal quantities have been
rounded to reflect the accuracy of the estimate, and thus the numbers
may not sum due to rounding.
