ORVANA REPORTS Q4 FY2024 PRODUCTION AND EXPLORATION UPDATE FROM OROVALLE, SPAIN
Juan Gavidia , CEO of Orvana stated:
he added.
The drilling program in Q4 FY2024 was focused on Area 208, oxide orebody, to convert inferred resources into indicated resources and targeting to extend the mineralization to the east, adding new resources.
Mineralization in Area 208 is located in oxide structures into limestone dipping to the east and usually affected by faults, which causes displacements of mineralization and width changes. See figure 1.
El Valle FY2025 drilling program continues focused on converting the oxides inferred material into measured and indicated material.
The greenfield drilling program in FY2025 will be focused on Ortosa-Godan Project, located three kilometers northwest of our Carlés mine, and within the same gold belt. The exploration program is focused on two areas: Ortosa and Godán. In both cases, the mineral potential is in relation to intrusives. In Ortosa, the mineralization was intersected along 300 m in several bands of calcic skarn and breccias with sulfides trending N40ºE located between 100 m and 200 m below surface. There is potential to extend the mineralization towards NE and at depth. In Godán, drilling program proved the presence of mineralization in the contact between the intrusive and sedimentary rocks with calcic skarn bands dipping 60-70º ESE over 200 m of strike potential. According to current drilling information and based on the dip and mineralization of the skarn, there is a potential connection with Carlés skarn.
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 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.
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.
Q4 FY2024 financial highlights will be released with the year-end financials, expected mid-December, 2024.
FY2025 guidance will be released with FY2024 year-end financials.
