TORONTO, Dec. 30, 2020 /PRNewswire/ -- Orvana Minerals Corp. (TSX: ORV) (the "Company" or "Orvana") announces the filing of its annual information form for the year ended September 30, 2020 (the "AIF"), and independent technical reports on the Don Mario Oxide Stockpile Project (the "OSP Technical Report") and the Orovalle Operation (the "2020 Orovalle Technical Report").

The AIF, the OSP Technical Report and the 2020 Orovalle Technical Report are available under the Company's profile at www.sedar.com and on the Company's website at www.orvana.com.

"Orvana is ending 2020 on a high note as it is delivering solid technical reports of its mineral reserves in Spain and Bolivia. Our filings today, once again, show Orvana's upside for years to come; and demonstrates our ability to execute on our plan to maintain stable production while continuing to replenish depletion year-by-year", stated Juan Gavidia, CEO of the Company.

OSP Technical Report

Orvana retained DGCS S.A. ("DGCS") to prepare a technical report for the Don Mario Oxide Stockpile Project, in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101").

The Company, through its wholly owned subsidiary EMIPA, is the owner of the Don Mario Operation ("Don Mario"), a set of assets that includes Las Tojas ore body, and the previously mined out Lower Mineralized Zone ("LMZ"), Upper Mineralized Zone ("UMZ") and Cerro Felix mines, plus the Processing Plant and the Tailings Storage Facility. Operations at Don Mario were temporarily suspended in the first quarter of fiscal 2020 and is currently in care and maintenance. The UMZ deposit, depleted in 2017, generated a 2Mton mixed copper oxide stockpile (the "Oxide Stockpile") with gold and silver grades during its mine life. Since fiscal 2018, the Company has been evaluating metallurgical alternatives to process the Oxide Stockpile, involving different international metallurgical consultants. The evaluation concluded that a sulphidization circuit would maximize the value of the Oxide Stockpile. The construction of the sulphidization circuit and ancillary facilities to process the Oxide Stockpile remains subject to the favorable completion of technical and economic analysis, and the availability of funding.

The OSP Technical Report highlights are:

Forward-looking statements are necessarily based upon a number of estimates and assumptions that, while considered reasonable by the Company as of the date of such statements, are inherently subject to significant business, economic and competitive uncertainties and contingencies as particularly set out in the notes accompanying the Company's most recently filed financial statements. The estimates and assumptions of the Company contained or incorporated by reference in this news release, which may prove to be incorrect, include, but are not limited to,  the various assumptions set forth herein and in Orvana's most recently filed Management's Discussion & Analysis and Annual Information Form in respect of the Company's most recently completed fiscal year (the "Company Disclosures") or as otherwise expressly incorporated herein by reference as well as: there being no significant disruptions affecting operations, whether due to labour disruptions, supply disruptions, power disruptions, damage to equipment or otherwise; permitting, development, operations, expansion and acquisitions at El Valle and Don Mario being consistent with the Company's current expectations; political developments in any jurisdiction in which the Company operates being consistent with its current expectations; certain price assumptions for gold, copper and silver; prices for key supplies being approximately consistent with current levels; production and cost of sales forecasts meeting expectations; the accuracy of the Company's current mineral reserve and mineral resource estimates; and labour and materials costs increasing on a basis consistent with Orvana's current expectations.

A variety of inherent risks, uncertainties and factors, many of which are beyond the Company's control, affect the operations, performance and results of the Company and its business, and could cause actual events or results to differ materially from estimated or anticipated events or results expressed or implied by forward looking statements. Some of these risks, uncertainties and factors include fluctuations in the price of gold, silver and copper; the need to recalculate estimates of resources based on actual production experience; the failure to achieve production estimates; variations in the grade of ore mined; variations in the cost of operations; the availability of qualified personnel; the Company's ability to obtain and maintain all necessary regulatory approvals and licenses; the Company's ability to use cyanide in its mining operations; risks generally associated with mineral exploration and development, including the Company's ability to continue to operate the El Valle and/or Don Mario and/or ability to resume long-term operations at the Carlés Mine; the Company's ability to successfully implement a sulphidization circuit and ancillary facilities to process the current oxides stockpiles at Don Mario; the Company's ability to acquire and develop mineral properties and to successfully integrate such acquisitions; the Company's ability to execute on its strategy; the Company's ability to obtain financing when required on terms that are acceptable to the Company; challenges to the Company's interests in its property and mineral rights; current, pending and proposed legislative or regulatory developments or changes in political, social or economic conditions in the countries in which the Company operates; general economic conditions worldwide; and the risks identified in the Company's disclosures. This list is not exhaustive of the factors that may affect any of the Company's forward-looking statements and reference should also be made to the Company's Disclosures for a description of additional risk factors.
