VANCOUVER, BRITISH COLUMBIA, Feb 3, 2016 (Marketwired via COMTEX) — Prospero Silver Corp. (PSL) ("Prospero") is pleased to announce that it has entered into a new agreement with Exploraciones del Altiplano, S.A. de C.V. ("Altiplano"), a privately held Mexican Company, in respect of new work programs on the San Luis del Cordero property in Durango State, Mexico ("Cordero"). A previous agreement, dated August 29, 2008, contemplated Prospero completing an exploration program exploration at Cordero with staged payments of cash; the issuance of Prospero shares and certain exploration expenditures on the property, leading to Prospero acquiring 100% ownership, subject to a residual 2% NSR royalty for Altiplano. Due to difficult market conditions, Prospero was not able to keep pace with the cash and expenditure requirements of that 2008, and had to rely on informal accommodations from Altiplano in order to retain its interest in the Cordero property. The 2008 agreement called for cash payments totaling US$450,000; US$1,650,000 in exploration expenditures and the issuance of 392,000 (post-consolidation) Prospero shares. To date, Prospero has paid US$102,333; made US$1,081,577 in exploration expenditures and issued 108,000 shares.

Particularly in the context of Prospero's recently announced agreement with Golden Minerals Company ("Golden Minerals") (nyse mkt:AUMN)(AUM) for the possible development of a mine at Cordero's Sta. Rosa vein, Prospero and Altiplano recognized the need to update their formal Cordero property agreement. Reference is made to Prospero news releases dated November 17, 2015 (agreement with Golden Minerals; discussed below) and October 7, 2014 (publication of an NI 43-101 compliant resource estimate).

The new agreement with Altiplano provides for Prospero to complete its acquisition of the 100% of the Cordero property by making staged issuances to Altiplano of a total of an additional 600,000 Prospero shares over the next 20 months, subject to Altiplano retaining a residual 2% NSR royalty interest. This new Cordero agreement remains subject to acceptance by the TSX Venture Exchange. Any share issued to Altiplano under this new agreement will be subject to the customary 4-month hold periods.

Golden Minerals has commenced studies on the Santa Rosa vein. Dewatering of the historic mine workings has started, to be followed by collecting and assaying fresh samples from the exposed vein, and metallurgical test work. This metallurgical test work will be used to determine what changes might need to be made, if any, to the existing crushing, milling, and flotation circuits at Golden Minerals' existing processing facilities. Golden Minerals also plans to carry out drilling for mine planning, as well as seeking to establish an expanded resource. Upon completion of such confirmatory work over the coming months, and assuming it is satisfied with the outcome of its investigations, Golden Minerals will proceed with engineering and permitting for mining of the Santa Rosa vein system.

The Cordero Project. The NI 43-101 compliant resource estimate on the Cordero Santa Rosa vein system was disclosed in the Report on the Initial Resource Estimate for the San Luis Del Cordero Project, dated October 1, 2014, (the "Cordero Technical Report") and filed under Prospero's issuer profile on SEDAR (www.sedar.com) on November 18, 2014 (see p. 54):

Prospero's 2015 agreement with Golden Minerals deals only with the Santa Rosa vein system. Prospero plans to consider further exploration with a view to expanding the resource of the Santa Rosa East Skarn, with additional drilling if and when market conditions permit.
