Guyana Frontier Reports Drilling Program at Five Star Gold Project

VANCOUVER, Nov. 27, 2012 /PRNewswire/ – Guyana Frontier Mining Corp. (“Guyana
Frontier”) is pleased to announce that Mulgravian Ventures Corporation
(“Mulgravian”, a private Canadian exploration company) has begun a
diamond drilling program on the Five Star Gold Project (“Five Star”),
located in northwest Guyana, South America. The initial drilling
program at Five Star is planned for a total of up to 10,000 metres over
the next twelve months, with the final drilling meterage total
dependent upon results.

Highlights of Five Star 2012 Exploration and 2013 Exploration Plans

        --  Prospecting and geological mapping, trenching, soil auger
            geochemical, and diamond drilling programs are underway;
        --  An airborne magnetic and radiometric survey is complete over
            all areas of Five Star;
        --  Construction of an airstrip and improvements to Five Star road
            access are planned; and
        --  2013 program and budget presented by Mulgravian totals
            approximately US$6.7 million.

A joint venture was formed in April 2012 on Five Star with Mulgravian as
operator holding a 51% interest and Guyana Frontier holding a 49%
interest (see Guyana Frontier news releases dated April 17 and July 11,
2012). Guyana Frontier previously elected not to contribute to the 2012
Five Star program, and will be subject to standard dilution of its 49%
interest in Five Star according to the terms of the joint venture
agreement.

The technical work disclosed in this document was supervised, reviewed
and approved by Robert Lunceford, M.Sc., CPG, who is a Qualified Person
as defined in National Instrument 43-101 (“NI 43-101″).

About Five Star

Five Star consists of 17 mining permits and 8 prospecting permits, which
cover an area of approximately 25,065 acres (10,144 hectares) near the
settlement of Matthew’s Ridge, Guyana. Guyana Frontier acquired its
100% interest in Five Star from two separate underlying vendors, Case
Development Company Ltd. and Marcel Waaldijk (the “Underlying
Vendors”), with each of the Underlying Vendors currently maintaining a
3% net smelter returns royalty (“NSR”) on their respective permits.
Each NSR is subject to buy-down provisions. Mulgravian earned its 51%
working interest in Five Star from Guyana Frontier by incurring minimum
exploration expenditures and property acquisition costs of US$2.0
million, and by purchasing Guyana Frontier common shares and exercising
Guyana Frontier common share purchase warrants totalling CDN$630,000.

On May 10, 2011, Guyana Frontier filed a technical report in respect of
Five Star on SEDAR compliant with the standards of NI 43-101, available

events or developments that Guyana Frontier expects or anticipates will
or may occur in the future, including such things as planned
exploration activities at the Five Star property, the operation of the
joint venture between Guyana Frontier and Mulgravian, future business
strategy, competitive strengths, goals, expansion, growth of Guyana
Frontier’s businesses, operations, plans and with respect to
exploration results, the timing and success of exploration activities
generally, permitting time lines, government regulation of exploration
and mining operations, environmental risks, title disputes or claims,
limitations on insurance coverage, timing and possible outcome of any
pending litigation and timing and results of future resource estimates
or future economic studies.

Often, but not always, forward-looking statements can be identified by
the use of words such as “plans”, “planning”, “planned”, “expects” or
“looking forward”, “does not expect”, “continues”, “scheduled”,
“estimates”, “forecasts”, “intends”, “potential”, “anticipates”, “does

such words and phrases or state that certain actions, events or results
“may”, “could”, “would”, “might” or “will” be taken, occur or be
achieved.

Forward-looking statements are based on a number of material factors and
assumptions, including, the result of drilling and exploration
activities, that contracted parties provide goods and/or services on
the agreed timeframes, that equipment necessary for exploration is
available as scheduled and does not incur unforeseen break downs, that
no labour shortages or delays are incurred, that plant and equipment
function as specified, that no unusual geological or technical problems
occur, and that laboratory and other related services are available and
perform as contracted. Forward-looking statements involve known and
unknown risks, future events, conditions, uncertainties and other
factors which may cause the actual results, performance or achievements
to be materially different from any future results, prediction,
projection, forecast, performance or achievements expressed or implied
by the forward-looking statements. Such factors include, among others,
the interpretation and actual results of current exploration
activities; changes in project parameters as plans continue to be
refined; the existence of weather conditions suitable for exploration
activities; future prices of minerals; possible variations in grade or
recovery rates; failure of equipment or processes to operate as
anticipated; the failure of contracted parties to perform; labour
disputes and other risks of the mining industry; delays in obtaining
governmental approvals or financing or in the completion of
exploration, as well as those factors disclosed in Guyana Frontier’s
publicly filed documents. Although Guyana Frontier has attempted to
identify important factors that could cause actual actions, events or
results to differ materially from those described in forward-looking
statements, there may be other factors that cause actions, events or
results not to be as anticipated, estimated or intended. There can be
no assurance that forward-looking statements will prove to be accurate,
as actual results and future events could differ materially from those
anticipated in such statements. Accordingly, readers should not place
undue reliance on forward-looking statements.
