Mirasol Signs Agreement to Option its Newly Generated Coronación Copper/Gold Project in Chile






Mirasol Resources Ltd. (TSX-V: MRZ) (OTCPK: MRZLF) is pleased to announce the signing of a definitive agreement with First Quantum Minerals (TSX:FQM) for its Coronación Copper/Gold Project in Northern Chile. The Project was generated by Mirasol as part of its ongoing Atacama-Puna generative program, further confirmation of Mirasol’s ability to attract quality partners on prospective exploration projects. With four partnership agreements now active, Mirasol continues to build a unique portfolio of exploration assets in Chile.


Mirasol’s President and CEO, Norm Pitcher, stated: “We are pleased to partner with FQM to advance the Coronación project, and look forward to results from the coming field season. With this agreement, Mirasol further expands its portfolio of quality exploration targets being tested by majors in the prolific Mio Pliocene belt of Chile.”


Terms of the Agreement


Mirasol granted to FQM the option to earn-in 80% of the Project over 6 years by:


  • Making annual cash payments totaling US$ 875,000;
  • Completing at least 10,000m of drilling; and
  • Delivering a NI 43-101 compliant Prefeasibility Study Report


FQM is committed to completing 3,000 m of drilling and a systematic geophysical program on the Project over the first 24 months of the Agreement. Following this period, FQM is required to spend a minimum of US$500,000 per year over the term of the Agreement. FQM will be the operator during the option period. 


Following the completion of the 80% earn-in, FQM will have a one-time option to acquire the remaining 20% on terms to be negotiated between the parties. If this option is not exercised, the parties will form a participating joint venture to further fund the development of the Project.


Coronación Project Overview


The 1,200 ha Coronación project is in Region II of Chile near the border with Argentina at an altitude of 4,000 to 4,600 m ASL. The project is located on a major NW structural trend associated with several Andean porphyry deposits (Figure 1).


Work completed by Mirasol indicates the potential presence of a porphyry/breccia system intruding a layered Miocene aged volcanic sequence of dacitic domes and pyroclastic units. Alteration consists of an advanced argillic lithocap (alunite/jarosite) developed in the central-eastern side of the property and intermediate argillic alteration (white micas) in the western portion of the property, along with pervasive, and locally vuggy silica alteration (Figure 2).


These two distinct and coincident areas display affinities to a high sulfidation epithermal system to the east, with the western side displaying a more typical porphyry deposit related style of alteration. Alteration signatures have been interpreted using ASD spectral analysis and the geochemistry is supportive of these interpretations. Geochemical sampling has defined a large 600 by 800 m Cu-Mo geochemical anomaly on the western side within the overall 3 by 2.5 km alteration halo (Figure 3).


Mineralization occurs as sheets and stockworks of banded quartz veins with up to three phases of silica emplacement recognized. Relic sulfide boxworks within the veins and wall rocks contain iron oxides (hematite-goethite and jarosite), with secondary copper and manganese oxides occurring along (or lining) fractures.


Mirasol looks forward to a successful season of exploration work at Coronación and will update its shareholders on material developments at the Project.
