TORONTO , Oct. 29, 2026 /CNW/ -- Orvana Minerals Corp. (TSX: ORV) (OTCQX: ORVMF) (" Orvana " or the " Company ") is pleased to report exploration results from its El Valle and Carlés deposits in Spain for the second half of fiscal year 2026, ended September 30, 2026 ("H2 FY2026"). The Company's ongoing exploration programs at El Valle and Carlés are comprised of infill drilling to improve geological confidence in known mineralized zones and brownfield drilling to test for extensions of those zones, with the objective of supporting future updates to the Company's Mineral Resource estimates.

•    Drilling Summary

A total of 53 drill holes were completed during H2 FY2026 across the El Valle–Boinás and Carlés deposits.

•  Breccia East

Of the total 5,687 metres drilled during H2 FY2026, 3,959 metres were infill drilling aimed at improving the geological interpretation of the mineralized zones and providing additional data to support the potential conversion of Inferred Mineral Resources to Indicated Mineral Resources in a future Mineral Resource update. There is no certainty that any Inferred Mineral Resources will be converted to Indicated Mineral Resources. The remaining 1,728 metres consisted of brownfield drilling, which the Company interprets as indicating continuity at depth of one of the mineralized bands. This interpretation will be further assessed as part of future brownfield drilling programs.

Drill hole locations, orientations, and reported intercepts are illustrated in Figures 1 through 3, and listed in Tables 1-5 in this news release. These figures provide plan and sectional views of the drilling completed during H2 FY2026, together with historical drilling in these areas. 

Figure 1. Level 420 – Breccia East

The Breccia East zone is interpreted to occupy a fault zone located at the contact between limestone and sandstone. The latter acts as a relatively impermeable barrier to hydrothermal fluids, causing Au and Cu mineralization to precipitate along the structure (Figures 2 and 3). Breccia East consists of subangular to rounded clasts supported by a hematitic clay matrix with visible native copper in some drill holes.

The upper part of the structure is bounded by Tertiary rocks along a broadly sub-horizontal contact at approximately 465 metres elevation. To the east, an Alpine thrust places Middle Cambrian carbonate rocks of the Láncara Formation over Tertiary rocks and Upper Cambrian sandstones of the Oville Formation. The structure remains open at depth and will be further evaluated as part of future exploration programs. (Figures 2 and 3)

The zone is further affected by NW-SE fault system that produces significant offsets and variations in the thickness of the mineralized zone, resulting in a structurally complex setting (Figure 1).

The Breccia East structure comprises a series of subvertical bands whose thickness varies from south to north, with average widths of approximately 20 metres in the southern sector, narrowing to around 7 metres in the northern sector. Gold mineralization within these bands is typically concentrated in horizons with true widths of 2 to 3 metres and average grades of approximately 4 g/t Au. Locally higher-grade zones have been intersected in the southern portion of the structure, as demonstrated by DDH 26BX1118, which returned 15.08 m at 10.68 g/t Au. Gold mineralization is occasionally accompanied by copper mineralization, as observed in DDH 26BX1116, which returned 1.79 m at 7.21 g/t Au and 1.49% Cu.

The drilling program carried out has improved the understanding of the geometry and continuity of mineralization within Breccia East, increasing confidence in the geological model. In addition, the brownfield drilling results indicate that the mineralization remains open at depth and will be the subject of further evaluation in future exploration campaigns.

•  Area 208

At Area 208, three holes totalling 742 metres (482 metres infill and 260 metres brownfield) were drilled in Q3 FY2026. Results are presented in Table 2.

Mineralization in Area 208 is concentrated within bands, with variable thickness (between 5-10 m) of altered skarn and semi-jasperoid breccias within the limestone; subsequently, the intrusion of porphyry dikes led to silicification and mineral enrichment of these bands. The arrangement of the mineralized bands in contact with the limestone and sandstone units, together with the presence of porphyritic dikes, is similar to that described in Breccia East, suggesting a correlation between the two structures.

•  Boinás East

Boinás East is a magnesian skarn that has developed along the contact between intrusive and carbonate units. The metallic mineralization consists of chalcopyrite, bornite, and magnetite, and is associated with Au-Cu mineralization. One infill hole (108 metres) was drilled in Q3 FY2026 to complete the delineation of a mining stope in the Boinás East skarn. Results are presented in Table 3.

•  Carlés

At the Carlés mine, 1,197 metres were completed between 1,046 metres of infill (major part of the program) and 151 metres of brownfield drilling. The drilling program was conducted to define the northeastern extension of the Carlés Northwest mineralized zone between the -35 and +50 levels. The zone remains open at depth and will be evaluated in future drilling programs. Results are presented in Table 4.

Quality Control

Infill and brownfield drill holes 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 70%<6 mm. The coarse-crushed sample is further reduced to 70%<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 by 85% to a nominal -200 mesh using an LM2 bowl-and-puck pulverizer. 150 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 one-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. Sampling is carried out in batches of a maximum of 30 samples for the fire test and 42 samples for the acid digestion test, with the first and last samples being analyzed twice, also a standard and a blank is inserted in every batch by laboratory personnel. Gold values exceeding 16.7 g/t Au are automatically repeated by the metallic screening method, to confirm the grade of the sample. For Breccia East and Area 208 core samples is used a 1000 g sub-sample of each split and 250 g sub-samples are split. 50 g samples are twice analyzed. In case of the twice analysis do not match, a metaling screening method is used to confirm the grade.

In addition to the controls inserted by laboratory personnel, geologists insert certified reference material (CRM), blanks and duplicate samples into the sample stream. The on-site senior geologist reviews the results prior to acceptance of the assay results. Orovalle repeats the entire batch analysis if the standard falls outside acceptable limits. If a blank or duplicate is observed to fail, 20% of the batch is re-assayed. If the 20% that is re-assayed does not match the original analysis, then the entire batch is re-analyzed.
