Golden Arrow Resources Corporation [TSX-V: GRG, FSE: G6A, OTCQB: GARWF], (“Golden Arrow” or the “Company”) is pleased to report that it has acquired, via staking, the Rosales Copper Project in Region III, Chile (“Rosales” or “the Project”). Initial reconnaissance work indicates that Rosales has several priority target areas characterized by zones of near-surface copper stockwork mineralization, potentially related to larger mineralized systems at depth. Initial sampling results from the Project returned up to 5.74% Cu.
“The Golden Arrow technical team has a keen interest in Chile as a mature mining jurisdiction that currently offers undervalued projects with excellent upside and the potential for low development costs, with reasonable acquisition and transaction fees. The team is enthusiastic about expanding the Company’s activities in Chile, and has reviewed dozens of precious and base metal projects to select for further evaluation those with the best potential for value creation. With copper prices rising rapidly, the Rosales Project has emerged as an excellent candidate, with the opportunity for both high-grade copper and additional metals,” stated Joseph Grosso, Golden Arrow Executive Chairman, President and CEO.
The Rosales Project is adjacent to claims hosting the currently operating small-scale underground Margarita mine, which exploits a copper stockwork zone with malachite-azurite-cuprite-chalcocite mineralization. The Margarita mine lies along a structural trend that continues to the southwest onto the Rosales Project. Mineralized occurrences along this trend on the Rosales Project were sampled and returned values between 0.37% and 4.37% Cu from five rock chip samples in an area of 100 x 200 metres. [Golden Arrow cautions that proximity to a mineralized occurrence does not indicate that mineralization will occur in sufficient quantity or grade on Golden Arrow’s property that would result in an economic extraction scenario.] Additional initial sampling throughout the Project outlined several other target areas, including approximately three kilometres to the northwest, where samples returned up to 5.74% Cu (see Figure 1: https://bit.ly/32z6Vs7). Based on the initial results, Golden Arrow has applied for an additional 824 hectares of adjacent mineral rights.
The 1,450 hectare Rosales Project is road-accessible and is situated less than 90 kilometres from the mining centre of Copiapo, with world-class exploration and mining infrastructure readily available. The Company is embarking on a Phase 1 exploration program that is expected to include detailed mapping and sampling, as well as ground magnetics and IP/resistivity geophysical surveys.
Rosales Copper Geology Overview
The Rosales Copper Project is situated in the Atacama Region, in a prolific mining region that hosts multiple large precious and base metal mines. Large mineral deposit types in the area include: iron-oxide copper gold (Candalaria, Mantos Verde), porphyry copper-gold (Inca del Oro), epithermal gold-silver (El Peñon, Guanaco) and Maricunga gold deposits (Cerro Casale-Caspiche, Refugio, Marte, Maricunga).
The Rosales Project is underlain by Jurassic-aged volcanic-sedimentary sequences, overthrust to the east by Triassic aged sediments. These sequences were later intruded by a dacitic dome and related felsic dykes, of probable Paleocene-Eocene age. Finally, a sinistral strike-slip fault system was emplaced to the east of the project where the Margarita Mine is found.
The initial reconnaissance program at Rosales identified two general areas of prospective mineralization: The Margarita Mine trend (MMT), and the NW Target (see Figure 1).
The MMT is a 3.5-kilometre-long structural corridor, oriented northeast-southwest, mainly defined by a felsic dyke. Situated within the corridor, the Margarita Mine is a small operating underground mine with mineralization known to extend to at least 200 metres depth; the mined zone is open at depth (L. Bocanegra, Pers.Comm June 2020). Plus 1% copper values are hosted in crackle breccias and veins along lithologic boundaries and fault traps, extending outwards from the structural corridor up to 200 metres. Approximately one third of the southwest part of the MMT is located within the Rosales Project, and similar mineralization has been found in this part of the trend on the Rosales property at surface. Chalcocite and chrysocolla was identified in outcrop, filling fractures and disseminated in the andesites, in an area covering 100 x 200 metres. Five rock chip samples from this area averaged 2.53% copper with a highest value of 4.37 % Cu. There are further indications of a manto-type mineralization two to four metres thick in this zone.
Based on geological mapping interpretation, the projected strike extension of the MMT to the southwest on the Rosales concessions should intercept a limestone unit at the base of the Jurassic sequence which could be a prospective host for replacement style copper mineralization. This conceptual target will be further evaluated with geophysical methods.
The NW Target is located 2.7 kilometres to the northwest of the MMT. It includes outcrop with veinlets and fractures hosting quartz-chalcocite-copper oxides within an area measuring 1,500 by 400 metres. This mineralization is hosted by porphyritic andesite and dacite, which may represent a dome complex. Eight chip samples collected from old trenches and pits throughout the target area averaged 3.19% Cu and 13.9g/t Ag with a highest value of 5.74% Cu and 37.1g/t Ag. Most of the chip samples were taken over 2 metres of width from trenches between 50 and 400 metres apart. The anomalous silver values together with the presence of low temperature opaline-silica veinlets in the dacite suggests a possible epithermal system at depth. Two samples from the east end of the target of quartz-chalcedony veins contained low metal values.
Reconnaissance sampling also detected four other showings with mineralization in old pits as shown within blue outlines in Figure 1. Six samples returned values ranging from 1.42% to 4.66% Cu; Additional mapping and sampling work is planned to further assess these areas.
Following the receipt of these encouraging initial results, Golden Arrow has applied for new concessions to cover the east and north extension of the MTT, adding 825 new hectares to the project. These applications are in progress.
The Company also wishes to report that it is not proceeding with its option of the Indiana Gold-Copper project in Chile.
Methodology and QA/QC
Field samples were shipped for preparation and analysis at ALS Laboratories, an internationally recognized assay service provider. Samples were prepared at their facility in Copiapo, Chile and assayed for gold by Fire Assay/Atomic Absorption finish and analyzed for a multi-element package by ICP-OES following a four-acid digestion at their laboratory in Lima, Peru.
The results of the Company’s exploration program have been reviewed, verified (including sampling, analytical and test data) and compiled by the Company’s geological staff under the supervision of Brian McEwen, P.Geol., VP Exploration and Development to the Company. Mr. McEwen is a Qualified Person as defined in National Instrument 43-101, and has reviewed and approved the contents of the news release.
