Claudia Gold Silver Project

Overview

The extensive Claudia Gold-Silver Project has five epithermal prospects with multiple drill-ready targets. The Claudia project was staked in 2004 as part of Mirasol’s Santa Cruz project generation strategy. Following up reconnaissance targets identified additional mineralization centres that led to more staking and the establishment of a sizeable land position. In 2012 Mirasol discovered the large 15 km long Curahue vein trend that had until that time been hidden by thin gravel cover.  At Curahue, Mirasol has identified six large vein trends with surface rock chip and channel  assays up to 5.86 g/t Au and 220 g/t Ag. 

For additional details on the geology of the Claudia project see the Further Information section below.

The Claudia prospects lie between 15 and 35 km to the south of the Cerro Vanguardia mine which adjoins the Mirasol claims. The world-class Cerro Vanguardia gold-silver mine (owned by CVSA, a joint venture 92.5 % owned by AngloGold Ashanti and 7.5 % by Fomicruz S.E., the Santa Cruz provincial mining company), has total district resources and past production of 8.6 Moz gold and 135 Moz silver.  From February 2016 to January 2017, CVSA and Mirasol were in a joint venture which completed 7,525 m of reverse-circulation (RC) and diamond core (DDH) drilling at the project. The majority of the drilling was focused on the Io vein, a 2.2 km long vein zone in the Curahue prospect. This drilling outlined a body of gold and silver mineralization.  The majority of the remaining vein trends were not drill tested or only received cursory drill testing. Mirasol is undertaking a comprehensive review of all new technical information generated by CVSA and is actively seeking a joint venture partner to continue drill testing at the gold – silver targets at the project.

Project Details

The Curahue trend, Io vein drilling has outlined a 600 m long, open-ended body of Gold/Silver mineralization that starts from a few metres below surface and has been tested to depths of 135 m. Drilling intercepts report to thin, high-grade epithermal veins which occur within vein and veinlet zones defining broader composited intervals of lower-grade mineralization, such as:

  • High-grade vein: 0.6 m at 11.72 g/t Au and 1,224 g/t Ag (0.6m at 32.13 g/t AuEq60 *).
  • Vein and veinlet composite: 13.0 m at 0.81 g/t Au and 105.2 g/t Ag (13.0 m at 2.56 g/t AuEq60 *)

* AuEq60 - Gold Equivalent is calculated via the formula: Gold g/t + (Silver g/t  /60)

Scout drilling by the former JV partner of the Curahue Trend, Europa and Calisto vein zones delivered a best intersection from an RC drill hole at Europa returning 2 m at 4.90 g/t Au and 14.2 g/t Ag, starting from surface. Follow-up drilling of this intersection and further drilling of the large Curahue trend is warranted.

Three diamond core holes were also drilled at the Rio Seco prospect and returned broad intersections of epithermal veining with anomalous gold and silver assays. The epithermal vein textures are consistent with those occurring at the top of an epithermal precious metal system, suggesting the potential for higher gold and silver grades at depth. Further exploration drilling at the Rio Seco prospect is warranted.

At the Laguna Blanca-Alien and Cilene prospects, Mirasol has identified indications of epithermal mineralization with trench channel and surface rock chip samples, returning assays of up to 1.2 m at 5.74 g/t Au and 42.7 g/t Ag, and 10.17 g/t Au and 49.0 g/t Ag respectively, reporting to epithermal veins. The targets at the Cilene prospect have not been previously drill tested.

Mirasol remains fully committed to advancing exploration at the Claudia Project and its multiple prospects, some of which have outcropping strongly mineralized gold – silver veins that have not been drill tested.
