Orvana Reports Q2 FY2022 Production, and announces 196.50 meters @ 0.53 g/t Au intercept at Greenfield Project in Orovalle, Spain

TORONTO, April 15, 2022 /PRNewswire/ -- Orvana Minerals Corp. (TSX: ORV) (the "Company" or "Orvana") is pleased to report production results and drilling updates from Orovalle, Orvana's unit in Spain, for the second quarter of fiscal year 2022 ("Q2 FY2022"), being the period ended March 31, 2022.

• 0.53 g/t Au over 196.50 meters intercepted in Lidia, Orovalle, Spain
• Q2 FY2022 production of 10,595 gold equivalent ounces
• 6,642 m of infill drilling
• 1,447 m of greenfield drilling

Juan Gavidia, CEO of Orvana: "Our exploration program continues producing excellent outcomes, reinforcing Orvana's internal growth potential to increase resources in Spain."

He added: "This has been a challenging quarter in terms of production in Spain due to the COVID-19 impact on the workforce in the first half of the quarter, supply chain strains all around Europe affecting the availability of spare parts, and the nationwide transport strike in March. Since early April supply chain channels have been reactivated, production restarted, and we are in the process of reviewing and optimizing the production plan for the second half of the year".

• Production of 10,595 gold equivalent ounces, a 33% decrease from Q1 FY2022. Production impacted by the temporary operations stoppage in March as a result of the nationwide transport strike in Spain.
• The Company is in the process of reviewing its operations and costs as a result of the temporary stoppage in March, and expects to be in a position to provide a more comprehensive update of the impacts on operations as part of the Q2 FY2022 reporting process in May.

Orovalle's gold porphyry Lidia Project is located in the Navelgas Gold Belt, 20 km from El Valle mine. 

Lidia occurs within the easternmost of the Navelgas fracture systems. A granodiorite intrusive outcrops over an area of approximately 1 km². It is dissected by a set of northeast trending mineralized quartz veins and affected by different alteration phases.

The drilling program started in fiscal 2021 with 1,017 meters drilled. The second phase started in December 2021, focused on defining the continuity of Au mineralization into the intrusive. Four drill holes, totaling 1,405 meters were drilled in the first half of FY2022, confirming the presence of gold in the granodiorite, averaging 0.53 g/t Au over 196.50 meters (DDH 22LIDIA04).

The Company expects to continue the program in Lidia in September 2022 drilling two sections, to the North and to South from current drilled area respectively, in order to prove continuity of  Au mineralization in N-S strike and at depth.

Ortosa-Godán Project is located three kilometers northwest of the Carles mine, at the same gold belt.

Orovalle started an exploration drilling program at the end of August 2021 in order to define the skarn continuity and check the oxide mineralization related to N40ºE structures. The Company disclosed first quarter fiscal 2022 results in the press release dated January 18, 2022. During Q2 FY2022, 426 meters were completed in one drill hole. Results from drill hole samples are pending, the information will be provided in due course.

The drilling campaign is still in progress, targeting to confirm the continuity of the mineralization intersected in drillhole 21ORW05: 20.66 g/t over 2.9 meters.

The drilling program continued with its focus on upgrading inferred resources, with a total of 6,642 m of infill drilling completed in Boinas South and Breccia East.

598 meters were drilled during Q2 FY2022 completing the infill drilling program. Around 200 Kt of Inferred resources were converted into Measured and Indicated resources as result of the infill drilling campaign completed in Carles West.

Greenfield drill hole samples were sent to an external laboratory (ALS Laboratory) for analyses. Infill drill hole samples were analyzed in Orovalle's Laboratory.

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 (in Orovalle Laboratory) 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.
• In case of the samples sent to an external laboratory, 30 g samples are analyzed for Au by fire assay with an atomic absorption (Au AA-25) and 35 elements by ICP (ME-ICP41) after an aqua regia digestion. When Au and Ag values are >100 ppm and Cu and As values are >10,000 ppm, specific analysis methods are used to determinate the final grade.

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.

Q2 FY2022 financials will be released mid-May, 2022.
