TORONTO, Oct. 19, 2021 /PRNewswire/ - Orvana Minerals Corp. (TSX: ORV) (the "Company" or "Orvana") is pleased to provide production results for the fourth quarter of fiscal year 2021 ("Q4 FY2021"), and full FY2021, and provides drilling update for Q4 2021 at Orovalle, Spain.
Juan Gavidia, CEO of Orvana stated: "The Orvana Team is glad to have delivered another strong operating year, allowing our strategic developments in Argentina and Bolivia to advance. The minor production pause resulting from the temporary suspension of the TSF pumping circuit in Orovalle was dealt with in an efficient and expeditious manner, and we anticipate that we will recoup the delayed production volume in the following months. We look forward to a successful fiscal year 2022, both, with a reliable Orovalle operation, and with positive developments in our two other international assets".
FY 2021 Production Highlights:
- Consolidated production of 63,108 gold equivalent ounces (47,413 gold ounces, 6.3 million copper pounds and 166,427 silver ounces).
- Metal production was slightly below Guidance mainly due to the mid-August Plant stoppage caused by the assessment of corrective measures to the tailings pumping circuits, in turn, impacted by the failure of a legacy open-pit wall. Underground mining continued operating throughout the plant stoppage, generating a stockpile that will be the basis to catch-up FY2021 delayed production into FY2022.
Q4 FY2021 Operational Results:
- Metal production: 8,621 gold ounces, 1.3 million copper pounds and 32,563 silver ounces.
- Q4 FY2021 metal production was negatively impacted by the temporary stoppage of activities at the plant in August 2021.
- 5,351m of diamond drilling, pursuant to aggressive resources annual program. Highlights:
- 28.22 g/t Au over 11.00 meters in East Breccia.
- 13.86 g/t Au, 129 g/t Ag and 3.00 % Cu over 3.30 meters in Boinas South.
- 9.35 g/t Au and 0.83% Cu over 5.1 meters in Carles West.
- Orovalle: Strong cash flow generation based on stable production plan. Continue exploration drive to keep replenishing, and expanding, the resource base. Renew 5-Year Life of Mine Plan, as has been the case for the last five years.
- Taguas: Issue new PEA in Q1 FY2022. Start Infill Drilling Program, required to develop Pre-Feasibility Study, in Q1 FY2022, subject to financing completion.
- EMIPA: Make decision on Oxides Stockpile Project in FY2022. Subject to approval and financing, construction planned for FY2023; with a 3-year production life between 2024 and 2026. Scoping studies for a subsequent project regarding reprocessing tailings will be underway in FY2022. Comprehensive exploration program started in FY2021 to continue throughout FY2022, with non-drilling field and cabinet work.
- FY2022 guidance will be released with FY2021 year-end financials.

Table 1. Orovalle Drilling Q4 FY2021
Highlights per Area (see detailed assays in Table 2):
- East Breccia: 11.00 meters with 28.22 g/t Au. Drilling advancing to the North converting Inferred resources into M&I, and getting better grades, as part of the objectives set for FY2021.
- Boinas South: 3.30 meters with 13.86 g/t Au, 129 g/t Ag and 3.00% Cu. Mineral expansion is open upwards with copper mineralization at depth and to the North.
- Carles West: 5.05 meters with 9.35 g/t Au and 0.83% Cu. Drilling campaign will be completed in Q1FY2022 targeting Inferred resources conversion.
- Boinas East: Stope definition drilling was executed according to mine production plan.
- A208 East: 724 meters of exploration drilling were completed in the quarter. Results are under review and will be disclosed shortly.
East Breccia (BX)
Infill drilling program advancing to the North converting Inferred resources into M&I resources. Mineralization consist of zones with high gold grades and variable copper content in a shear zone which is verticalized towards the north. Structure is open at depth.
Boinas South (SB)
Drilling campaign continue focused on the down dip open area, targeting skarn material with higher gold and copper grades. The structure remains open at depth and to the North. An infill drilling program will be completed in FY2022, connecting the Black Skarn area around the intrusive contour.
Carles West (CW)
Carles West is formed by several skarn bands between 2 and 10 meters width, with an extension of 100 meters NW-SE and dipping 65º NE. It is located in the west part of the Carles deposit where the mineralization is developed in the contact between a granodioritic intrusive, sandstones (Furada Formation –Upper Silurian) and limestone (Rañeces Formation – Devonian).
4,409 meters in 28 drill holes were completed before 2007. In the second half of FY 2021 an infill drilling campaign was started in order to convert Inferred resources into Measured and Indicated. Up to end of September 2021, 2,738 meter of 4,000 planned were executed in 13 drill holes. Several parallel calcic skarn bands (pyroxene and garnet skarn) were intersected, mineralized with Magnetite, Arsenopyrite, Chalcopyrite and Bornite. It is expected that drilling program will be concluded in Q1 FY2022.
The analytical work for the brownfield and infill drilling programs are being performed by the Orovalle laboratory, which is ISO 9001:2015 certified. Sample preparation was carried out at the El Valle facility. All diamond core samples have been prepared using the following procedure, once split:
The core samples are dried at a temperature of 105ºC and then crushed through a jaw crusher to 95%<6 mm. The coarse-crushed sample is further reduced to 95%<425 microns using an LM5 bowl-and-puck pulverizer. An Essa rotary splitter is used to take a 450 g to 550 g sub-sample of each split for pulverizing. The remaining reject portion is bagged and stored. The sample is reduced to a nominal -200 mesh using an LM2 bowl-and-puck pulverizer. 140 g sub-samples are split using a special vertical-sided scoop to cut channels through the sample which has been spread into a pancake on a sampling mat. Samples are then sent to the laboratory for gold and base metal analysis. Leftover pulp is bagged and stored.
After sample preparation, 30g samples are analyzed for Au by fire assay with an atomic absorption spectroscopy (AAS) finish and two-gram samples for Ag, As, Bi, Cu, Hg, Pb, Sb, Se, and Zn by ICP-optical emission spectroscopy (ICP-OES) after an aqua regia digestion.
The reported work has been completed using industry standard procedures, including a quality assurance/quality control ("QA/QC") program consisting of the insertion of certified reference material, blanks and duplicates samples into the sample stream.
The exploration update was prepared under the supervision of Guadalupe Collar Menéndez, a qualified person for the purposes of NI 43-101 and an employee of Orovalle Minerals S.L., a subsidiary of Orvana.
