Mountain Boy Minerals Ltd. (TSX VENTURE:MTB) (or the "Company") is pleased to
announce that it has filed an updated NI 43-101 technical report in regard to
the Company's Silver Coin project, located near the town of Stewart, British
Columbia (the "Report"). The Report was prepared by Minarco-Mine Consult
("Minarco") and is available on SEDAR (www.sedar.com). The Report includes an
updated resource estimate incorporating the assay results of eighteen holes that
the Company's joint venture partner drilled during the fall of 2010 which had
not previously been reported or included in resource estimates. This updated
resource estimate represents an overall increase in the average gold grade of
10.9% and an 11.1% increase in the number of resource ounces compared with those
previously reported. In comparison, gold resources have increased by category as
follows: from 191,300 measured ounces (oz), 644,300 indicated oz and 655,200
inferred oz, to 218,410 measured oz, 624,006 indicated oz and 813,273 inferred
oz. The updated resource estimate incorporates a total of 732 drill holes
(88,645 meters) plus 76 trenches (1,447 meters). The Silver Coin project
includes 26 contiguous claims with a net area of 1247 hectares and is a joint
venture with Jayden Resources Inc. (Jayden 70% with an option to earn an
additional 10%).


Resource Estimate

Using a base case cut-off grade of 0.3 grams gold per ton ("gpt") the Report
identifies the following gold, silver and zinc resource:

At the 0.3 gpt cut-off grade the estimated Measured and Indicated resource is
24.13 million tons grading 1.08 gpt gold for a total of 842,416 ounces of gold,
4.45 million ounces of silver and 91.17 million pounds of zinc. The estimated
Inferred resources comprise an additional 813,273 ounces of gold, 6.69 million
ounces of silver, and 128 million lbs of zinc.


The resource remains open along strike to the north and south. The two
southernmost holes from the 2010 drilling, both located within 150 metres (m) of
the currently modeled southern pit boundary, intersected excellent intervals of
gold mineralization including 55m grading 8.42 gpt gold in hole SC10-311 as
reported in the Company's news release of October 14, 2010. Readers are advised
to access the Report for detailed technical information.


Work Plan

The Company's joint venture partner plans to conduct a major in-fill drilling
program at Silver Coin during the 2011 exploration season with the primary goal
of upgrading the inferred resource to the indicated or measured categories. Such
activities will both support completion of a prefeasibility study and
potentially increase the size and grade of the resource. Based on, and subject
to the success of the proposed 2011 program, the Company's joint venture partner
is planning to produce a prefeasibility study by the first quarter of 2012. The
Company's joint venture partner is also planning on undertaking several of the
recommendations contained in the Report including geotechnical drilling,
continued baseline environmental studies, waste rock studies to determine if the
waste is potentially acid forming, complete the site-based studies to support a
prefeasibility study and metallurgical testing to include comminution tests,
locked cycle tests, optimization of the flow sheet, zinc recovery testing and
additional testing to optimize the cyanide recovery from concentrate. The
Company's joint venture partner also plans to initiate groundwater hydrology and
chemistry testing in existing and new wells on the property.


Ed Kruchkowski, P. Geo., a qualified person under National Instrument 43-101,

the companies.
