TORONTO, ONTARIO -- (MARKET WIRE) -- 11/12/12

Rio Verde Minerals Development Corp. (TSX:RVD) ("Rio Verde" or the "Company") announced today the financial results and related management's discussion and analysis for the three and nine months ended September 30, 2012.

Review of Q3 2012 Financial Statements

During the three months ended September 30, 2012, Rio Verde invested C$1,652,587 in exploration costs at its three active exploration projects. The Company incurred a net loss and comprehensive loss of C$889,887 (C$0.01 per share) in the period, comprised of compensation, professional fees, and office and administration expenses.

As at September 30, 2012, Rio Verde had working capital of C$11,247,350, and total assets of C$51,693,963, including C$39,440,199 in exploration and evaluation assets.

Bonito Phosphate Project

During the quarter, the Company changed the name of its primary phosphate project, previously known as the Fosfatar Phosphate Project, to the Bonito Phosphate Project ("Bonito"). The name was changed in recognition of the nearby municipality of Bonito, in the state of Para.

In Q3 2012, Rio Verde started four new agronomic tests on Thermophosphate produced at the Sapucaia Target at the Bonito Phosphate Project. Two additional agronomic tests are planned for Q4 2012. The information obtained from these tests will be used to start the process of product registration at the Brazilian Agriculture Ministry. Product marketing, and negotiation of letters of intent (LOIs) with potential off-takers, is also well underway.

The Company expects to receive the final mine design for the Bonito Phosphate Project from Promon Engenharia Ltda. in Q4 2012. Conditional upon a positive result from this final design and approval from the Company's board of directors, the Company will seek to secure debt in Q4 2012, with production currently expected to commence in Q1 2013.

Sergipe Potash Project

In Q4 2012, the Company will continue the 3D seismic programs at the Sergi Project and Capela Project at the Sergipe Potash Projects. These seismic programs will allow for preliminary evaluation of each project's potential and will improve the Company's understanding of the local geology. Conditional upon positive results from the seismic campaign, a drill program is planned for Q1 2013.

Phosphate Pipeline

In Q4 2012, the Company will be conducting first-pass drilling programs at the Mandacaru, Santa Quiteria and Caninde Phosphate Projects, for a total of approximately 1,500m of drilling. Follow-up drilling programs have conditionally been planned for each of the projects, and will be evaluated upon completion of the initial drilling. The goal of this exploration is the delineation of at least one NI 43-101 Inferred resource.

About Rio Verde

Rio Verde Minerals Development Corp. (TSX:RVD) is a publicly traded company focused on the exploration and development of fertilizer projects in Brazil. The Company's goal is to become the leading Brazilian fertilizer mining and development company by selecting prime assets that are near infrastructure, with known mineralization, in regions without significant social or environmental issues. The Company plans to fast-track the best projects to development to create stakeholder value.

Rio Verde holds one potash project and a portfolio of phosphate projects in Brazil. Potash and phosphate fertilizers have favourable supply and demand dynamics, and Rio Verde has a significant cost advantage by being based in Brazil, a country that imports about 90% of its potash and 50% of its phosphate needs. Rio Verde's near-term primary objective is to focus its potash exploration on establishing a Canadian National Instrument 43-101 resource.
