(Golden Arrow Resources, 29.Apr.2021) — Golden Arrow Resources Corporation provided an update on exploration activities at its three most active projects, including the first results from the on-going trenching program at the Esperanza property of the Flecha de Oro gold project, Argentina.
Phase I of the trenching program at Esperanza is focused on a nine square kilometer area where numerous gold-bearing quartz-veins have been identified at surface. Of particular note are results from a single vein, mapped over 540 meters of strike extent, that returned significant gold intervals in two separate trenches located approximately 160 meters apart, including:
- five meters averaging 2.98 g/t gold, including two meters averaging 6.21 g/t gold, in trench TE-10, and;
- one meter interval averaging 5.52 g/t gold in trench TE-6, located 160 meters east, in the same vein (see Figure 1: https://bit.ly/3udLQOw).
Golden Arrow VP Exploration and Development Brian McEwen commented, “We have seen from our previous surface sampling that there is widespread gold in the system at Esperanza, so we are encouraged to find some broader intervals in the near-surface that will help us vector into the heart of the system.”
Additional details from the trenching program, as well as other work in progress, are included below. In addition to its exploration programs, Golden Arrow is continuing with its project acquisition efforts by constantly reviewing new opportunities to add to its exploration pipeline.
Flecha de Oro Gold Project, Rio Negro Argentina
The Flecha de Oro Project includes the La Esperanza, Puzzle and Maquinchao exploration properties, consisting of 9,968, 1,952 and 2,000 hectares respectively, in central Rio Negro Province. The Project lies within the Somuncara Massif, where low and high sulphidation gold systems have been explored for since the first discovery of gold in the area in 1995. Examples of similar projects in the area include the Calcatreu low sulphidation gold-silver project located 165 kilometres to the southwest, hosting 746,000 oz of Indicated gold equivalent resources and a further 390,000 oz of Inferred AuEq resourcesi.
At the La Esperanza property, Golden Arrow has identified similarities in size and geologic style to the Cerro Vanguardia district to the south in Santa Cruz province that has produced 4.5 million ounces of goldii, which is now being used as an exploration model.
[Readers are cautioned that results from other companies, including on properties proximal to those controlled by the company, are not indicative of expected Golden Arrow results, as there has been insufficient exploration on these properties. These facts are simply used to aid in the exploration of these properties.]
Golden Arrow commenced the trenching program at Flecha de Oro in December 2020, with the initial work undertaken at the Puzzle property. Results from the first 10 trenches at Puzzle identified gold in multiple samples over significant widths in several trenches (see Figure 2: https://bit.ly/2R7PpqU), but at grades below the threshold targeted by the company. As a result, the Esperanza property has been prioritized for on-going exploration. Esperanza hosts multiple vein corridors defined by outcropping quartz veins, boulders and quartz float. The areas sampled by the trenches reported in this news release returned high-grade gold samples in earlier surface sampling programs (see Figure 1, and company news releases dated 2 March 2020, 3 December 2019 and 25 September 2019).
Since the commencement of trenching at Esperanza on 1 March 2021, Golden Arrow has completed 20 trenches totaling 1,693 meters across surface quartz veins and sheeted veinlets that range from a few centimeters to two meters in width. Assays have been received for 10 of these trenches. An additional fifteen trenches are underway, and the Phase I program is expected to continue through most of May. A summary of the results from the first ten trenches is presented in Table 1.
Rosales Copper Project, Chile
Golden Arrow has awarded Quantec Geoscience Chile Ltda the contract for completing a new Transient Electromagnetic (TEM) surface geophysical survey at the Rosales Copper Project in May. The goal of the program is to detect and delineate prospective electromagnetic conductor responses, consistent with near-surface copper stockwork mineralization, potentially related to Manto-type mineralized copper systems at depth. The program will be executed in two phases:
- An initial test over approximately 300 hectares that includes known copper sulphide mineralization will be conducted and the results assessed to determine if the TEM technique successfully detects the mineralization.
- If successful, a second survey covering approximately 800 hectares will be completed.
Tierra Dorada Gold Project, Paraguay
The planned follow-up drill program at the Alvaro target has been delayed until permits are received that will allow deeper drilling. While it is possible to continue with the shallow (<20m) drill hole program allowed by the existing permit, after further review of the initial shallow drilling results and the new targets identified by the IP geophysical survey (see News Release of 9 January 2021) it was concluded that there was greater benefit to waiting to be able to drill the deeper holes. Granting of permits has been delayed by outbreaks of COVID-19 within several government agencies and elsewhere in Paraguay. In the interim, the Golden Arrow exploration team has commenced a detailed soil sampling program over the new geophysical targets that have no surface outcrop to refine drill targets in those areas. In addition, mapping, trenching and surface sampling programs at the Alvaro target, and regionally throughout the project, are ongoing.

Methodology and QA/QC
At the Flecha de Oro project, trenches were opened across the vein width and continued into the host rock on either side. Channel samples were cut along the trench walls with an electric saw and sampled in one-metre intervals. Samples were shipped for preparation and analysis at ALS Laboratories, an internationally recognized assay service provider. Samples were prepared at their facility in Mendoza, Argentina 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 company follows industry standard procedures for the work carried out on the Flecha de Oro Project, with a quality assurance/quality control (QA/QC) program. Blank, duplicate and standard samples were inserted in each batch of samples sent to the laboratory for analysis. Golden Arrow detected no significant QA/QC issues during review of the data.
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.
