Rio Novo Gold Announces Second Quarter 2012 Results and Provides Update on its Almas Gold Project

TORONTO, ONTARIO -- (Marketwire) -- 08/14/12 -- Rio Novo Gold Inc. (TSX: RN)(TSX: RN.WT) ("Rio Novo" or the "Company") has today filed its interim operational and financial results for the second quarter ended June 30, 2012. Interim Financial Statements and the accompanying Management's Discussion and Analysis ("MD&A") have been filed on SEDAR.

During the second quarter of 2012, the Company incurred a loss of US$3.8 million (US$0.03 per share) compared to a net income of US$7.1 million (US$0.06 per share) in the corresponding period of 2011. Among the factors that contributed to the net loss in the period were differences in foreign exchange due to US dollar and Brazilian real exchange rate fluctuations, which resulted in a loss of $1.4 million, and a gain of $1.1 million resulting from a share purchase warrant revaluation.

As at June 30, 2012, the Company had working capital of US$15.1 million, including cash of US$16.3 million.

Corporate Development Highlights

--  Development drilling was completed at the Vira Saia deposit to support
    resource modeling for the Almas Gold Project definitive feasibility
    study ("DFS").

--  Exploration activities continue to delineate additional mineralization
    west and northwest of Vira Saia. A second pass follow-up drilling
    program is planned for 2013. The program will focus on proving up the
    continuity of the higher grade areas, as well as testing open edges of
    mineralization.

--  Deep core drilling was initiated at the Paiol Deposit to test for higher
    grade extensions of the main gold zone. Based on geologic modeling and
    previous deep drilling (10.0m @ 8.0 g/t Au in FD-81 and 8.0m @ 9.2 g/t
    Au in FD-66), the Company believes higher grade gold mineralization
    extends beyond the currently identified resource, and two deep drill
    holes were completed with this in mind (a third hole was attempted but
    lost). Both holes hit the main gold zone penetrating up to 17m thickness
    (down hole). However, the +500m holes experienced major deviation (up to
    60m from the target) and appear to have missed the higher grade shoot.
    On this basis, and considering the difficulty and expense of the deep
    drilling, the Company has decided to discontinue further drilling on
    this target at this time and focus on the DFS completion.

--  Regional exploration initiatives continued to define new prospects
    within the Almas Greenstone Belt. Mapping and sampling have been
    conducted at the Jacobina Target, with results from rock chip sampling
    indicating the presence of gold in concentrations of up to 17 g/t.
    Similar activities are planned for eight new targets located on the Nova
    Prata trend, a 25 km greenstone belt parallel to the Paiol trend.

--  At the Guaranta Project, the company plans to complete initial
    engineering and scoping studies for the X1 Deposit by early 2013. As
    previously noted, the Company views X1 as a strong deposit, but believes
    that additional resources will be necessary to satisfy its corporate
    goals at the project. Work at the Guaranta Project will therefore be
    concentrated on adding these additional resources to increase the
    overall size of the project. The main focus for exploration is expected
    to be the nearby Matupa Target, which is located in one of the largest
    placer gold mining districts in Brazil, with at least eight porphyry
    centres identified. The Company recently commenced exploration on this
    target. Mapping has been completed and trenching is in progress, with
    drilling expected in Q4 2012.

--  A first-pass core drilling program was initiated at the Toldafria
    Project in Caldas, Colombia. As of June 30, 2012, approximately 3,500m
    had been drilled, representing ten completed drill holes. The program is
    expected to total 5,000m of diamond drilling, and is scheduled for
    completion in late August 2012.

Almas Gold Project Update

--  The development of the DFS continues and the timeline has been extended
    to incorporate additional studies, particularly relating to pit slopes
    angles, final pit optimization and final capital expenditure and
    operating expenditure estimates. These studies are being conducted in
    coordination with Rio Novo's independent consultant engineering firms,
    Conestoga-Rovers Associates ("CRA") and Pincock Allen & Holt - Brasil
    ("PAH").

--  In particular, pit slope angles in saprolite for Cata Funda and Paiol
    are being reviewed to incorporate new data from hydrologic studies and
    geotechnical drilling completed in Q2.

--  The Paiol and Cata Funda mine plans are being optimized, mostly due to
    the revision of the pit slopes currently underway. A phased pit plan,
    optimized production schedule, and different bench heights are part of
    the planned pit optimization that could potentially increase grade and
    decrease waste stripping, particularly in the early years of the mine
    operations.

--  Initial DFS capital expenditure estimates are significantly higher than
    those contained in the Preliminary Economic Assessment ("PEA") due to
    cost inflation, higher production rates, more accurate engineering, and
    project scope changes since the date of the PEA. The company is
    reviewing the capital expenditure estimates for improvement.

--  These additional studies, while improving the overall understanding of
    the Almas Project, will delay the final decision by about three months.
    The company now expects to be in a position to make a final decision on
    Almas during the last quarter of this year.

--  The Company has finalized the detailed engineering for the power supply
    required by the Almas Project, and has moved on to the acquisition of
    the necessary licenses for construction of the power line.

--  The Company continues to progress in its efforts to secure sufficient
    project finance for the Almas Project, and will continue to work with
    its financial advisor, Endeavour Financial, towards this end. By the end
    of the second quarter, Rio Novo had received six indicative offers for
    senior debt based on the PEA cash flow. Five of these offers were made
    by international banks, while the remaining offer was put forward by a
    Brazilian bank. A positive construction decision and finalization of
    project finance will remain conditional upon receiving the final results
    from the DFS process.
