ROAD TOWN, British Virgin Islands, Dec. 08, 2024 (GLOBE NEWSWIRE) -- Aura Minerals Inc. (TSX: ORA) (B3: AURA33) (OTCQX: ORAAF) (“Aura” or the “Company” ) is pleased to announce encouraging exploration and drilling results from several high-potential projects in Brazil.
These include the Pé Quente Project, located 34 km from the Matupá Project’s X1 Deposit; near-mine expansion at the Paiol Deposit, part of the Almas Mine; and Aura Carajás, all of which are located in Brazil. These results highlight the Company’s ongoing success in advancing its exploration portfolio and reaffirm Aura’s commitment to expanding its resource and reserve base, positioning the Company for sustained growth. Highlights Pé Quente Project The Pé Quente gold deposit is emerging as one of the most significant disseminated gold systems in granitic environments within the Alta Floresta Gold Province, similar to the X1 Deposit and Serrinhas.
6,200m of the planned 7,500m program completed with six high-priority targets identified to date. Drilling confirmed historical high-grade gold intercepts previously identified by Graben Mineração SA (refer to press release dated May 22, 2024) in the Nilva zone. In addition, drilling also identified a new zone (Nilva North) which expands the footprint of mineralization along strike to the northeast.
Significant intercepts include: Hole FPQD-0010 (Nilva) 0.96 g/t Au over 132.00m, including 4.
05 g/t Au over 3.00m and 4.00 g/t Au over 2.
00m. Hole FPQD-0020 (Nilva North): 1.18 g/t Au over 63.
90m, including 4.14 g/t Au over 8.00m.
Pé Quente is one of several promising targets surrounding the X1 Deposit within a 50km radius, where Aura has completed a Feasibility Study. Paiol Deposit, Almas Mine A 13,000m infill and extension drilling campaign confirmed the high-grade ore body's continuity at depth, supporting potential underground mining and adding ounces to the Inferred Mineral Resources below the current pit. Significant intercepts include: Hole PAI-004 1.
40 g/t Au over 101.10m, including 4.20 g/t Au over 26.
65m, 11.20 g/t Au over 7.00m.
Hole PAI-005 1.30 g/t Au over 49.05m including, 3.
70 g/t Au over 13.05m. Hole PAI-014 2.
8 g/t Au over 19m including 8.2 g/t Au over 3m and 1.5 g/t Au over 3m.
Further drilling down dip of the ore body is required to delineate underground potential and open a possibility of having underground and open pit mines at the same time in the Paiol deposit. Located in one of the world's most prolific gold-producing environment, that in Brazil hosts over 80 million ounces of gold, offering exceptional potential for extending Aura's deposits and making new discoveries. Aura Carajás A 22,000m inaugural drilling campaign between 2023 and 2024 confirmed multiple zones of mineralization extending the strike to 8 kilometers between a southern and northwestern trend, which provides an excellent opportunity of different styles of IOCG mineralization to be explored.
Drilling has delineated semi-massive sulfide zones with higher grades (exceeding 1% Cu) within low (0.2% Cu to 0.5% Cu) have been identified, typically ranging from 15 to 20 meters in thickness, characterized by vein-hosted mineralization.
Additionally, semi-massive sulfide zones with high-grade copper (>1% Cu) have been observed, averaging approximately 5 meters in width (not true width).

These include SDE-008, 009, 010, 014, 0046 Quality Assurance and Quality Control Almas QAQC Measures Almas Gold Project QA/QC program requires that the following minimum number of control samples be inserted into the drilling samples being submitted to the laboratory: One high ore-grade and one low ore-grade CRM (or medium grade) in each analytical batch of 40 samples (5%) and a minimum of two blanks inserted in each batch mainly after mineralized zones. The control sample assay results of the internal QA/QC program were monitored, including the CRMs, pulp duplicates and sizing checks during preparation. Additionally, systematic checks of the digital database were conducted against the original signed Certificates of Analysis from the laboratory.
Aura Carajas QAQC Measures Drill core was sawed in the Project core shed and shipped to ALS, in Parauapebas, Pará-Brazil, where the samples were crushed, pulverized and homogenized, then pulp samples were sent to ALS Laboratory, in Lima-Peru, to conduct the analytical works, and analyze them for Gold using Fire Assay (Atomic Absorption – fusion 50 g aliquots) and ME-ICP61 analysis for determination of up to 34 elements by ICP/Digestion with aqua regia. For samples with Copper grades higher than 10,000 ppm, the analysis ME-OG62 was applied. The remaining coarse and pulverized rejection of the samples were returned to the Project facility for storage.
Serra da Estrela (Aura Carajas) had routine quality control procedures which ensured that every batch included five percent of commercial standard (high, medium or low grade), and five percent of blank sample. ALS laboratory has its own routine quality control procedures which ensured the insertion of blanks, commercial standards and duplicates into each batch of samples to be analyzed. All analytical results and certificates from both laboratories were provided separately and digital copies of the files were stored in the digital database.
Pé Quente QAQC Measures Quality Assurance and Quality Control Analytical work was carried out by SGS Lab, Geosol Laboratory in Vespasiano, Minas Gerais, Brazil. Drill core samples were crushed, pulverized and homogenized at SGS Geosol laboratory in Goiânia, Goias, Brazil, then pulp samples were shipped to SGS Lab in Vespasiano. All samples were analyzed for gold values determined by fire assay method (code FAA505) with atomic absorption spectrometry finish on 50g aliquots.
SGS has routine quality control procedures which ensure that every batch of 20 prepared samples includes one sample repeat, three commercial standards, and blanks. SGS QA/QC measures are independent of Aura. Aura established a standard QA/QC procedure for the drilling programs at Serrinhas by inserting one blank, one standard, and one duplicate for every 40 samples.
