Picachos

Picachos Project

The Company's primary focus is on the Picachos Project, located approximately 50km south east of the coastal city of La Serena, Chile, 8km west of the existing large Andacollo copper-gold project operated by Teck Resources (Carmen de Andacollo) and the mining town of Andacollo (population approximately 10,000 people), and 10km south of the privately owned Tambillos copper mine.

The Project is at an altitude of approximately 800m above sea level and is well positioned for infrastructure with existing HV power approximately 3km east of the Project area and is serviced from two all-weather access roads.

The Company completed two very succesful drilling campaigns in 2014 with a view to fast-tracking the Picachos Project into production as soon as possible.   In addition to the excellent grades achieved in both the 2014 drill programs, the Company currently plans to toll treat Picachos ore through one of a number of processing plants all located within close trucking distance of the Picachos mine.

Mineralisation

A review of available data and recent site visits have identified up to five separate zones of mineralisation with a combined strike length of over 8km contained within the Project area. In some areas the close relationship of these zones coupled with multiple occurrences of out-cropping wide zones of mineralisation, highlights the excellent potential for large scale open pit mining to take place.

Two distinct styles of mineralisation have been identified:

  1. A high grade “structural” style of mineralisation referred to as “vein” (typically 1 – 5m  wide) and
  2. A “lithological” related style of mineralisation or “mantos” (up to 50m wide and potentially wider in some areas). Preliminary geological studies estimate up to two separate zones of mantos mineralisation.

Mining History

Historic mining has focused mainly around the high grade vein, however in some areas the mantos has been mined up to 50m wide. Mineralisation generally occurs from one to five metres below the surface.

In 1994 a small drilling campaign was conducted, by Shell Chile replica rolex – Division Metales, in the north-west section of the Project area resulting in a number of high grade intersections including 6m at 3.5% Cu and 30.9g/t Ag from 41m and 9m at 1.6% Cu and 9.6g/t Ag from 46m. A channel sampling program was also undertaken by the current owners on the main Leoncito decline which resulted in an average grade of 1.3% Cu along its entire 110m length

Small scale mining of approximately 4,000 to 10,000 tonnes per month is presently being undertaken by replica watches private miners via small open pit and underground mining operations.

Ore is currently being trucked to a Chilean government owned processing plant (ENAMI plant) where it is processed.  Historic records provided by fire pump for sale the owners indicate typical average mine grades achieved from processing the Picachos ore include:

  • Oxide Ore     – 1.7% Cu
  • Sulphide Ore – 2.5% Cu
