Orosur Signs Anillo Option LOI for Non-Dilutive Funding of Up to US$3.5 Million

Orosur Mining Inc. (“Orosur” or the “Company”) (TSX:OMI) (AIM:OMI), a South American-focused gold producer, developer and explorer is pleased to announce that it has signed a non-binding letter of intent (“LOI”) to option its interest in the Anillo project (“Anillo”) in Chile to Asset Chile Exploración Minera Fondo de Inversión Privado (“AC”).

The LOI provides for a 45 day period of exclusivity (the "Exclusivity Period") to complete due diligence and negotiate and enter into a definitive option agreement and any other required documentation (the "Option Agreement").

The LOI contemplates that the Option Agreement (if entered into) will provide that AC may earn up to a 40% interest in Orosur’s interest in Anillo (the “Transaction”) pursuant to the following phased earn-in milestones (“Option”):

Ignacio Salazar, CEO of Orosur, said:

“After finalising the extension of the Codelco option term to January 2020, as announced on 5 November, 2014, we are delighted to have entered into an LOI with Asset Chile to option a minority share in our interest in the Anillo project. The Option Agreement will entail Asset Chile spending up to US$3.5 million in a three phased option and committing exploration expenditures to earn up to a 40% of Orosur’s interest. The objective of this expenditure is to make a discovery at Anillo.

This transaction is non-dilutive to Orosur shareholders and enables further exploration work to continue at Anillo with limited capital requirements by Orosur. We look forward to closing the transaction and welcoming Asset Chile as partners in our exploration efforts at Anillo.”

The LOI also contemplates that the Option Agreement (if entered into) would provide that Orosur would incorporate a new wholly owned subsidiary of Fortune Valley Resources, Inc. (“Newco”) and transfer or assign the Codelco option agreement to Newco. AC would then initially subscribe for an amount of Newco common shares (the “Shares”) equal to the 16% of the capital of the Newco for gross proceeds of US$850,000. AC would then have the option to elect to earn into up to 32.5% and up to 40%, by funding an additional US$1,250,000 and up to US$1,375,000, pursuant to the Option outlined above. Should AC not pay in full for the Shares in Phase 1, it shall be required to pay Orosur a break fee equivalent to US$250,000, unless the failure to pay is as a result of CORFO not approving the Transaction, in which case, AC shall be required to pay Orosur their accrued expenses incurred with respect to the Transaction. Should Orosur not fulfil its funding or other obligations, it would be required to pay AC a break fee equivalent to US$50,000.

Within 60 days of completion of the Phase 1 and Phase 2 exploration programmes, respectively, AC will have the obligation to notify Orosur in writing of its decision to elect to proceed. Should AC not fund the purchase of common shares in Phase 2, its interest in Newco shall be cancelled.

The Option Agreement would contain terms to provide that Orosur will remain the operator of Anillo and that each of Orosur and AC, as shareholders of Newco, will be equally represented on the Board of Directors of Newco and on the Technical Committee, each comprising four members. All funding proceeds would be used to perform exploration activities and studies as directed and agreed by the Technical Committee and shall be focused on generating a discovery at Anillo.

The LOI contemplates that Phase 1 exploration shall include a geophysics campaign and a minimum of 3,600 metres of Reverse Circulation (“RC”) drilling and have an estimated duration of up to 10 months. Phase 2 shall include an additional geophysics campaign and a minimum of 5,500 metres of RC drilling and have an estimated duration of up to 18 months. Phase 3 shall include further geophysical work and additional RC drilling and have an estimated duration of up to 18 months.

Amongst other customary conditions, closing of the Transaction shall be subject to the following conditions:

• Completion of due diligence
• Execution of the Option Agreement
• CORFO accepting the Transaction.
• Receipt of Phase 1 funding by Newco from AC and Orosur
• Transfer of Orosur’s option agreement with Codelco into Newco
• Regulatory approval, if any; and
• Approval of the Board of Directors of Orosur
