Marketwired Canada
Tintina Resources Inc. ("Tintina" or the "Company") (TSX
VENTURE:TAU)(OTCQX:TINTF) is pleased to announce that today it has filed a
National Instrument 43-101 compliant technical report (the "Technical Report")
for its Black Butte Copper-Cobalt-Silver-Gold property (formerly called "Sheep
Creek") located in central Montana. The report, entitled "Black Butte Copper
Project, Meagher County, MT, April 2012 Mineral Resource Update", and dated
April 30, 2012, is available on the Company's SEDAR profile at www.sedar.com.
Highlights:
-- The Lowry Deposit Middle Zone contains an Inferred Resource of 5.14 MMT
grading 2.60% Cu, 0.12% Co, 0.009 g/tonne Au and 14.6 g/tonne Ag at a
1.6% Cu cut-off grade.
-- Current total NI 43-101 Compliant Resources are 623 million lbs of
Inferred Copper Resource and 553 million lbs of Indicated Copper
Resource
Jerry Zieg, Vice President of Exploration, said: "The scale of the Black Butte
Copper project continues to grow as we surpass our corporate objective by
achieving a resource estimate for the project of 553 million pounds of copper in
the indicated category and 623 million pounds of copper in the inferred resource
category. Management believes that the evaluation of existing targets, together
with on-going exploration efforts will result in the discovery of additional
high grade copper resources on this promising property."
The Lowry Deposit Middle Zone is a tabular layer up to 52 meters thick of
copper-cobalt-silver mineralization with bands, veins, and masses of
chalcopyrite concentrated within a modestly dipping silicified breccia and shale
layer from 265 to 718.5 meters below the surface. The true thickness of the
moderately dipping mineralized zone approximates 90% of the drilled thicknesses.
Historic resources calculated by earlier operators are non-compliant with NI
43-101 standards and are not being relied upon for resource estimation purposes.
There is potential for additional resources in extensions of the Lowry Deposit
Middle Zone and in other Cu-Co-Ag deposits identified on the property.
The Mineral Resource estimate for the Lowry Deposit Middle Zone was prepared by
Mike Lechner, president of Resource Modeling Inc., an independent Qualified
Person as defined by NI 43-101. The drill hole database that was used to
estimate Mineral Resources consists of 4 drill holes completed by Cominco
American Inc. totaling 2,558.8 meters and 10 drill holes completed by Tintina
Resources Inc., totaling 6,715.2 meters. The Mineral Resource estimate was
completed by constructing a three dimensional computer block model with a block
size of 5 m X 5 m for the X and Y dimensions and 2.5 m for the Z dimension.
Three-dimensional wireframes were constructed to represent the Lowry Deposit
Middle Zone, the Volcano Valley Fault, and the Rose Fault, a northeast trending
high-angle structure. Drill hole composites 2.5 meters in length were generated
from the assay data after capping high-grade outliners and subsequently used to
estimate copper, cobalt, and silver grades using inverse distance weighting
methods and a dynamic anisotropy search strategy. The block grades were
validated visually and by comparing the grades with a nearest neighbor model. A
density of 3.35 g/cm3 was selected to tabulate resource tonnage based on 24
density determinations from fresh drill core collected from Tintina's 2010 and
2011 drilling campaigns. Tintina incorporated a rigorous quality
assurance/quality control (QA/QC) program for their 2010, 2011 and 2012 drilling
programs, including the submission of standards, blanks, and duplicates into the
assay stream that was submitted to their primary analytical laboratory ALS
Chemex. Historical assays were obtained from files donated to the University of
Montana drill core collection by Cominco American Inc. These files do not
contain original assay certificates, and attempts to recover these have so far
have been unsuccessful.
There are no material differences between the mineral resources disclosed on
March 19, 2012 and the mineral resources described in the Technical Report.
Jerry Zieg, Vice President of Exploration for the Company is a Qualified Person
for the purposes of National Instrument 43-101 and has reviewed and approved the
information of a scientific nature contained in this news release.
About Black Butte Copper Project
The Black Butte Copper Project is located approximately 17 miles north of White
Sulphur Springs, Montana, and lies along a well-maintained gravel road within
two miles of U.S. Highway 89. The property, originally explored by Cominco
American Inc. and BHP during the 1980's and early 1990's, consists of
approximately 12,225 acres of fee simple lands and mining claims and contains
sediment-hosted zones of Cu-Co-Ag syn-sedimentary massive sulfide
mineralization. The Company has completed over 39,300 meters of drilling since
initiating work in September of 2010 and has established Indicated and Inferred
Resources on the property including the Johnny Lee Deposit Upper Zone, Johnny
Lee Deposit Lower Zone and the Lowry Deposit Middle Zone (please see Company
News Release dated January 13, 2012 and Table 1).

The Company continues to explore additional mineralized zones within the
property area. Tintina is completing a Preliminary Economic Assessment (PEA) of
the Johnny Lee Deposit, planned for finalization by the end of Q2, 2012. The
company is also preparing an advanced underground exploration proposal which
includes an exploration decline and ancillary facilities for presentation to the
appropriate State authorities. All presently envisaged mine workings and
facilities would lie on private ranch lands.
