Fiore Intersects 2.67 Metres at 381 g/t Silver and 1.0 Metre at 501 g/t Silver at Cerro Tostado10 min read
FIORE GOLD LTD. (TSXV: F) (“Fiore” or the “Company”) is pleased to announce the results of the Phase I diamond and reverse-circulation (“RC”) drilling program at its Cerro Tostado project in Chile, following up on high-grade epithermal silver mineralisation previously intersected by three of eighteen holes drilled between 2010 and 2012 by Sociedad Quimica Y Minera de Chile SA (“SQM”). Cerro Tostado is located just south of the main and Fortuna zones of Yamana Gold’s flagship El Peñon Mine (Figure 1).

Phase 1 of the Cerro Tostado program included four oriented-core diamond drill holes targeting the previously-identified high-grade silver mineralisation, as well as two new targets identified from mapping, surface sampling and trenching (Figure 1). Holes TO17-001 and -002 confirmed the existence of high-grade silver mineralisation within broad envelopes of lower grade silver values (Figures 2 & 3). For example, the 1.0 m at 501 g/t silver intercept in hole TO17-001 occurs within an 18.8 m-wide zone averaging 70 g/t silver.
A previously unknown silver mineralized structure was also discovered in hole TO17-002, which ended in an 81-m wide zone with values up to 97 g/t silver over 1.0 m (Figure 3). Based on the style of mineralization at Yamana’s nearby El Peñon mine, additional drilling will be required to determine if this new zone also hosts a higher-grade silver core.
Tim Warman, Fiore’s CEO stated, “By drilling these initial oriented diamond core holes we’ve been able to confirm the north-south striking, steeply-dipping nature of these high-grade silver zones. We’re also pleased to have intercepted a second mineralized zone beneath the alluvial cover to the east of the main Cerro Tostado hill. Planning is underway for the next phase of drilling to test these structures along strike.”
The Cerro Tostado project consists of five concessions totaling approximately 1,500 ha located in Region II some 125 km southeast of Antofagasta. The project is approximately 12 km southwest and 8 km east-southeast of Yamana’s El Peñon and Fortuna mines respectively (see Figure 1), and along strike from the principal veins reported at the Fortuna mine. A large hill, Cerro Largato, forms a north-south elongated outcrop of argillic altered and brecciated rhyolite that intrudes and is in fault contact with porphyritic andesitic units and dacitic to rhyodacitic units towards the east and southeast. These outcropping units are surrounded by gravel and caliche covered areas. Alteration is most intense along the breccia bodies that are spatially related with the dominant N-S and NW-SE structural trends. Associated with the argillic alteration and structural trends are variable intensities of hematite-jarosite bearing veinlets.
Geological mapping and sampling, combined with Terraspec mineral analysis, has identified a possible advanced argillic lithocap of the type often found above high sulphidation epithermal gold deposits such as Barrick Gold’s new 6.8 million ounce Alturas deposit, also in Chile. Mapping identified several areas of strong silicification with some vuggy silica, along with alteration minerals including alunite and dickite, all of which are characteristic of high sulphidation systems. Bedrock sampling also identified elevated levels of arsenic in the same areas.
Along with the mapping program, approximately 30 line kilometers of reconnaissance IP and 12 line kilometers of more detailed IP surveying were carried out over two large outcropping areas of intense silica alteration. The gradient array was selected to help map suspected sulphide mineralization associated with a large zone of hydrothermal alteration at Cerro Tostado. In total, gradient IP surveys were conducted on 30 km of lines with 200 m dipoles to outline zones of alteration. Moderately strong chargeability anomalies associated with high resistivities are outlined over two topographical hills separated by about 4 km. Weaker chargeability anomalies occur in the covered pampa between the two chargeability anomalies.
Detail gradient array surveys with 50 m dipoles were conducted on 12 km of lines over the eastern chargeability anomaly to help map shallow vein systems that have been previously mapped and trenched. The gradient array identified multiple narrow resistivity targets that may be associated with vein systems. An abrupt change in orientation of the resistivity anomalies occurs near an area that was drilled extensively previously. Ongoing geological mapping may help explain this abrupt change in deviation.
One line of pole-dipole IP was surveyed on a 6.3 km line covering the two strongest chargeability anomalies and the weaker central anomaly. Results show shallow chargeability anomalies over the two strongest gradient anomalies and a deeper chargeability anomaly under cover in the pampa between the two shallow anomalies. The central anomaly under the Pampa was drilled with three RC holes.
All three RC holes (TO17-005, -006 and -007) intersected a succession of moderate to strong argillic altered dacite volcanics with wide zones of breccias containing varying amounts of pyrite (up to 5% locally) down to 400 m. The company believes that this explains the geophysical anomaly and no further work is planned on this target.
Technical Information and Qualified Person
Drilling at Cerro Tostado by SQM was carried out using a reverse circulation rig. Samples were collected every 1.0 m from intervals of interest. Samples were assayed for gold and silver, and in some cases for antimony and arsenic, by Andes Analytical Assay Limitada of Santiago, using the atomic absorption (AA) method. QA/QC procedures were confined to the insertion of a blank sample for every twenty samples. Standard reference materials do not appear to have been used. Fiore is confident that SQM’s sample preparation, security, analytical procedures and analyses were adequate for an early stage exploration property.
Samples re-assayed by Fiore consisted of either laboratory pulps (where available) or resampled coarse-reject material, all of which had been stored in a secure SQM facility since completion of the SQM programs in 2010-2012. Samples were transported by Fiore personnel to ALS Chemex Laboratories in Antofagasta Chile for preparation. Sample pulps were then sent to ALS Chemex Peru (Lima) Laboratory for analysis. Gold was assayed using a 50-gram gold fire assay with either an atomic absorption, or a gravimetric finish for samples initially reporting over 10.0 g/t gold. Silver was assayed using a 30-gram sample by fire assay and gravimetric finish for samples reporting over 100 g/t Silver.
Multi-element ICP-AES (33 elements, 4-acid digest) geochemical analyses were also carried out on each sample. Standard reference materials and blanks were inserted in each assay shipment as part of Fiore’s QA/QC program.
Drilling at Cerro Tostado by Fiore was carried out by AK Drilling International Perforaciones Ltda. using a truck-mounted diamond drilling rig for the oriented core drill holes (TO17-001, -002, -003 & -004), while the exploration geophysical test holes (TO17-005, -006 & -007) were done with a truck mounted reverse circulation rig. Samples from the oriented diamond drill holes were generally taken on 2.0 m lengths from intervals of interest, with some selected samples between 2 m to 0.5 m within mineralized or structural zones potentially related to anomalous silver mineralization.
Samples from the RC holes were collected every 2.0 m from intervals of interest. A 3-kg subsample was prepared using a riffle splitter, and the samples were transported by Fiore personnel in sacks with numbered seals to ALS Chemex Laboratories in Antofagasta Chile for preparation. Sample pulps were then sent to ALS Chemex Peru (Lima) Laboratory for analysis. Gold was assayed using a 50-gram gold fire assay with either an atomic absorption, or a gravimetric finish for samples initially reporting over 10.0 g/t gold. Silver was assayed using a 30-gram sample by fire assay and gravimetric finish for samples reporting over 100 g/t Silver.
Multi-element ICP (33 elements, 4-acid digest) geochemical analyses were also carried out on each sample. Standard reference materials and blanks were inserted in each assay shipment as part of Fiore’s QA/QC program.
