TORONTO, June 28, 2019 /CNW/ - Orvana Minerals Corp. (TSX:ORV) (the "Company" or "Orvana") is pleased to announce that further to its press release dated May 14, 2019 announcing that it had entered into a purchase agreement (the "Purchase Agreement") to acquire the Taguas gold property ("Taguas" or the "Property") located in San Juan Province, Argentina, the Company has received a preliminary economic assessment report ("PEA") from Wood, formerly Amec Foster Wheeler ("Wood").

Juan Gavidia, CEO of Orvana stated: "The Taguas property will be an open pit mining operation that is near-surface, and has a low-strip ratio, coupled with conventional heap-leach extraction.  The new asset will be an addition to the Company's portfolio and is expected to set the pace for growth and lower overall unitary costs across the Company.  Taguas' PEA outlines inferred resources of 494 thousand ounces of gold and 18.11 million ounces of silver at an estimated AISC of US$500 per ounce of gold; these are very positive, early indicators for Taguas as Orvana's third potential operation.  Mr. Gavidia added: "Orvana's exploration team, and the Wood Pre-Feasibility Study consultants are in the planning stages to advance Taguas to the next level, which would include step-out drilling on additional, nearby, near-surface, oxide targets in order to determine any potential increase of the current mineral resources. The execution of any additional work on the Property remains subject to Orvana obtaining sufficient financing to proceed forward."

Background of the Taguas Property

On May 14, 2019, Orvana entered into a Purchase Agreement with Compañía Minera Taguas S.A. (the "Vendor") pursuant to which, Orvana agreed to acquire (the "Transaction") the Property. In consideration for 100% of Taguas, Orvana will grant to the Vendor an indivisible net smelter royalty equal to 2.5% on all future metals production mined from the Property.

Taguas consists of 15 mining concessions over an area of 3,273.87 ha.  It is located in the Province of San Juan, Argentina, on the eastern flank of the Andes, between 3,500m to 4,300m above sea level.  The Property is approximately 25km north of Barrick Gold Corporation's Veladero mining operations and uses the same infrastructure to reach the Property. 

The Toronto Stock Exchange ("TSX") has provided conditional acceptance of Orvana's notice of the Transaction, pursuant to the TSX Company Manual. Closing of the Transaction is subject to the final acceptance of the TSX and a number of closing conditions including, without limitation, Orvana's completion of a corporate structure that is acceptable from a tax, corporate and legal perspective relating to the ownership of Taguas.

Preliminary Economic Assessment Report (PEA)

In connection with the Transaction, Orvana has received a PEA on Taguas from Wood, prepared by the following qualified persons: Antonio Peralta Romero, P.Eng., Principal Mining Engineer, Wood Canada Ltd., Vancouver; Joseph J. Kowalik PhD, QP MMSA Senior Consulting Geologist; Ronald G. Simpson, P.Geo., Mineral Resource Consultant, Geosim Services Inc.; and William Colquhoun, Pr Eng, FSAIMM, Principal Process Manager, Amec Foster Wheeler Peru S.A. (Wood).

The Property is host to a high-sulfidation epithermal gold-silver system hosted in altered tertiary age rhyolite volcaniclastic rocks. Supergene-oxidized gold-silver mineralization occurs on the south half of the Property.  The oxide gold-silver mineralization consists of sub-vertical, northeast striking mineralized structures in an envelope of lower grade mineralization.  The high-grade zones consist of relatively continuous mineralization with gold grades ranging from 0.2 g/t Au to over 4.0 g/t Au and 10 g/t Ag to over 50 g/t Ag.  Oxidation extends from surface to approximately 100m – 200m below surface. The present PEA refers only to this oxidized gold-silver mineralization occurring near surface.

PEA Highlights

• Pre-Tax NPV of US $55.1M at 8.0% discount rate
• Pre-Tax Internal Rate of Return (IRR): 21.7%
• After-Tax NPV of US $37.8M at 8.0% discount rate
• After-Tax IRR: 17.3%
• Payback Period (from start of operations): 3 years

• Initial Capital: US $92.8M
• LOM Capital: US $106.1M
• Estimated Average LOM Net Direct Cash Cost (C1): US $498/Au oz payable equivalent
• Estimated Average LOM All-In Sustaining Costs (AISC): US $519/Au oz payable equivalent

Mineral resources that are not mineral reserves do not have demonstrated economic viability. The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves and there is no certainty that the results of the PEA will be realized. The financial analysis in the PEA does not include the 2.5% royalty associated with the acquisition of the Property by Orvana. The PEA study is conceptual in nature and the PEA mine plan is based on 100% inferred resources. The projections, forecasts and estimates presented in the PEA constitute forward-looking statements and readers are urged not to place undue reliance on such forward-looking statements.  Additional cautionary and forward-looking statement information is detailed at the end of this news release.

PEA Mining & Processing

The mining method proposed for the Property in the PEA is conventional truck and shovel open pit mining.  The proposed recovery process will be crushing and agglomeration of mineralized material at a rate of 12,000 tpd, stacking in 6 m lifts on a permanent heap leach and gold and silver recovery from the heap leach pregnant solution in a carbon Adsorption-Desorption-Recovery (ADR) plant and electrowinning to produce doré gold bars.

Chris Wright of Wood supervised the preparation of the PEA, is independent of the Company and a qualified person as defined by National Instrument 43-101 and has reviewed and approved the technical disclosure reported herein. The PEA will be filed on SEDAR within 45 days from this news release.

Related-Party Transaction Exemption
