Historic exploration begins at iron, copper, gold and cobalt project in Chile  

The program will be carried out at the company’s San Pietro iron, copper, gold and cobalt mining project. 

On February 14, Golden Arrow Resources announced the start of a new diamond drilling program in Chile, in the San Pietro project, for iron, copper, gold and cobalt mining. The first stage covers 2,650 meters and seven holes, up to 20,000 meters of drilling budgeted for the year. 

The historic exploration of the project included more than 34,000 meters of drilling in 83 holes concentrated mainly on four targets with iron oxide, copper, gold (IOCG) and cobalt mineralization: Rincones, Colla, Rodeo and Radiss North. The first phase of drilling will test several new interpretations that have resulted from recent field programs to adjust the direction for subsequent holes. 

The San Pietro Project is hosted by andesite units in a Cretaceous volcanic-sedimentary sequence associated with intrusive rocks, including granodiorites and diorites of similar age. The Project is located east of the Atacama Fault system, an important north-south regional structure that was instrumental in controlling the location of ore deposits in the area. 

Mineralization at San Pietro is typical of an IOCG system, with addition of cobalt, and occurs in loopholes, veins, and mantles within a K-feldspar-chlorite alteration zone. These structures are rich in magnetite and specularite and in some cases calcite and develop mainly along NW-SE lineaments. 

In the first drilling phase of this year, two holes will be drilled in the area of the best historical copper intercepts to test a new geological model for the magnetite and copper mineralization mantles. Golden Arrow’s new detailed mapping indicates that some of Magnetite’s mantles are diving to the southwest as opposed to the overall historical model.  

The 100% owned San Pietro Project includes 18,448 hectares of exploration and exploration concessions in the Atacama region of Chile, approximately 100 kilometers north of Copiapó, in an active mining district that is home to all major iron oxide, copper-gold ores in Chile.
