Orvana commences drilling at Lidia Project in Spain and provides update on Carl?(C)s deep drilling results

TSX:ORV

TORONTO, Nov. 11, 2020 /CNW/ - Orvana Minerals Corp. (TSX:ORV) (the "Company" or "Orvana") is pleased to announce the commencement of exploration drilling at its Lidia project (the "Lidia Project" or "Lidia"), located 20 km in a straight line from the El Valle mine, in Asturias, Spain. An update is also being provided about the Carlés Deep drilling performed in fiscal 2020.

Lidia Project

The Lidia Project is comprised of one investigation permit covering 2,576 hectares in the Navelgas Gold Belt in the region of Asturias, Spain (see location in Figure 1). It is a historic project previously explored by Río Narcea Gold Mines Ltd. ("RNGM"). During RNGM's exploration campaign in 1998, hole Lin-4 was drilled, testing a copper/gold soil anomaly along the northern margin of the Linares intrusive complex. Lin-4 encountered a thick section of altered granodiorite averaging 0.4 grams per tonne gold over a width of 208 meters. The geochemistry and alteration are indicative of a gold porphyry system (Rio Narcea Gold Mines Ltd., 1998 Annual Report – "Navelgas Gold Belt" (page 14)).

Orvana has performed several exploration activities at the Lidia Project, starting with the validation of historical drill hole assay at its El Valle laboratory (re-logging and re-sampling); and continuing with 1:10,000 geological mapping, and rock sampling, in 2016. Between 2017 and 2018 a geophysics campaign was also completed.

4,000 DDH meters are planned to drill in two targets. One is a potential skarn mineralization along the western edge of the granodiorite (Target 1) and the other is a gold porphyry system (Target 2). See Figure 2. The drilling program is expected to be completed by March 2021.

Carlés Deep Drilling Update

Orvana has completed the analysis of its Carlés Deep drilling campaign carried earlier in the year. A total of 2,367 meters were drilled in one borehole plus 3 wedges. All four DDH's intercepted the targeted skarn orebody extension at depth, as expected (see Table 1). With the encouraging verification of the continuity of the skarn, 400 meters downdip, the Company will now assess the potential of this area in the context of a long term mine design strategy.

Mr. Raúl Álvarez, Head of Exploration of Orvana, stated: "We are optimistic about this new drilling campaign at Lidia, as historical data suggests the potential identification of a new gold project for Orvana. Lidia, and Carlés Deep, are the latest examples of our robust exploration commitment in the Asturias Region".  

Exploration Quality Control and Qualified Persons

The analytical work for the 2020 brownfield drilling program is being performed by Orovalle's laboratory, which is ISO 9001:2015 certified. Sample preparation was carried out at its El Valle facility. All diamond core samples has been prepared using the following procedure, once split:

• The core samples are dried at a temperature of 105ºC before being 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, 30 g 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. Ms. Collar Menéndez has approved the scientific and technical disclosure of the exploration results contained in this press release.
