TSX:ORV

TORONTO, Nov. 8, 2019 - Orvana Minerals Corp. (TSX:ORV) (the "Company" or "Orvana") is providing an update on operations for its EMIPA operations located in Bolivia and its Orovalle operations, located in Northern Spain.

EMIPA:
The Company has determined to suspend mining operations at Las Tojas effective on or before December 31, 2019 because of a higher than expected ore-grade operational mining dilution with more narrow, erratic and discontinued mineralized structures, which is resulting in uneconomic unitary cost per ounce.

Notwithstanding the suspension of mining operations at Las Tojas, the previously announced development and engineering of the oxides stockpile that has accumulated from past mining activities at Don Mario (the "Oxides Stockpile Project") continues to advance. The Company anticipates that, subject to the favourable completion of technical, economic and funding analysis, the sulphidization circuit and ancillary facilities will be in full production by FY2021 to process the oxides stockpile. During this one-year interim period, contractors will be developing the Oxides Stockpile Project at site, while undertaking care and maintenance of existing facilities.

The oxides stockpile has a mineral resource (Measured) of 2.18 million tonnes with an average gold grade of 1.85 g/t; and contains 386,950 oz of gold equivalent1. The stockpile resource was estimated in the 2016 Report (as that term is defined in endnote no. 1 below) on the assumption that the stockpile would be processed by floatation and would not be included in the carbon-in-leach circuit. However, during FY2018 and FY2019, the Company has been evaluating metallurgical alternatives to process the oxides stockpile, concluding that a sulphidization circuit would maximize the value of the stockpile. 

1 Cautionary Statement – Mineral resources that are not mineral reserves do not have demonstrated economic viability. The mineral resource for the oxides stockpile was prepared in compliance with National Instrument 43-101 and CIM guidelines, as set out in the Don Mario Mine Operation 2016 Technical Report dated January 27, 2017 and effective as of September 30, 2016 (the "2016 Report"). A copy of the 2016 Report is posted under the Company's profile on www.sedar.com. These mineral resources were estimated using a gold price of US$1,300 per ounce, copper price of US$3.00 per pound and silver price of US$18 per ounce, prices of which were used in the 2016 Report.

Subject to the ability to convert the estimated resources of the oxides stockpile into reserves, the Oxides Stockpile Project is expected to provide three full production years for Don Mario starting in FY2021.The Company will provide additional details regarding EMIPA and the development of the Oxides Stockpile Project as they become available.

Juan Gavidia, CEO of Orvana stated, "Given the anticipated near-term transition into our Oxides Stockpile Project, it is the right decision to suspend operations at Don Mario to mitigate a higher unitary cost burden onto the Company. Subject to a favourable outcome of the analysis of the feasibility of the oxides stockpile, we are committed to funding and building the Oxides Stockpile Project, which is expected to commence in early FY2021, with 33 months of expected low-cost gold and copper production,"  Mr. Gavidia continued, "as for our El Valle production, we have worked very hard over the past four years to ensure that the operations are stable, and delivery of gold production remains sustainable."

Technical Disclosure/Qualified Person

Mr. Gino Zandonai, M.Sc. Mining, CP, Mining Engineer is a Qualified Person as defined under National Instrument 43-101 Standards of Disclosure for Mineral Projects and he has reviewed and approved the technical information contained in the EMIPA section above.

Orovalle:
The Orovalle mining operations, located in Asturias Spain, consist of the El Valle and the Carlés mines, and include a mill operation.  OroValle is a stable producer of gold and copper with fiscal 2019 production of 64,327 ounces of gold and 5.0 million pounds of copper or 76,752 gold equivalent ounces.  In the fourth quarter of 2019, gold and copper production increased by 17% and 5% respectively compared to the previous quarter due to higher throughput, including a Carlés Mine short-term open pit project. 

Unitary costs at OroValle, reported in the third quarter, were US$987 COC and US$1,154 AISC and are expected to continue to trend downward year-over-year. Based on current gold prices and stable 2019 production numbers, Orovalle is expected to continue generating free cash flow in fiscal 2020.  Fourth quarter 2019 financial highlights and full guidance including COC and AISC will be released with the year-end financials, expected mid-December 2019.

Ongoing brownfield and infill drilling in and around the El Valle and Carlés mines is expected to continue strong conversion of resources into reserves and adding new resources to the ore bodies extending the current mine life.

Orovalle has a robust regional exploration package consisting of 45,164 hectares which includes concessions and investigation permits, some of which are still in progress.  Strategic near-term regional targets within our permits include:

  • The Ortosa-Gordan Target, located near the Carlés mine deposit: between 1981 and 2011, 37 diamond drill holes ("DDH") (9,833m) where completed; a 9-hole DDH (5,900m) program is planned for 2020 targeting high-grade skarns and oxide mineralization.
  • The Lidia target, located in the Navelgas Gold Belt, which is located approximately 20km west of El Valle: between 1998 and 2005, 5 DDH (1,472m) were completed; a 4-hole DDH program (2,000m) is scheduled for 2020, targeting skarn mineralization and disseminated gold in the intrusive.

The Company anticipates spending approximately $1.7M in regional greenfields targets in 2020 to add new mineral resources to the current portfolio.
