The Incahuasi property is located near the city of Salta, Argentina. The Las Burras-Incahuasi mineralized systems are hosted in Tertiary stocks, dykes and volcanics, and intrude into late Proterozoic sedimentary and Cambrian intrusive rocks. The region contains three separate showings and numerous occurrences with quartz, sericite, tourmaline and pyrite alteration. Mineralization occurs as stockworks, veins, porphyry and greisen settings. Incahausi itself is believed to host a gold porphyry system. Zones of highly anomalous gold are peripheral to each of these porphyry settings and previous work down played their potential as a gold play. These are vein and stockwork systems of quartz, pyrite, sericite, specular hematite and tourmaline that appear to represent a stage of mineralization later than, and peripheral to, the porphyries. These include:

  1. A zone of about 600 x 600 meters along the eastern margin of the most northerly of the porphyries. Of 191 prospecting samples collected, 17 were greater than 1 gm/t gold with a high of 5.8 gm/t. Silver values are also elevated with a high of 115 ppm.
  2. A 50 x 400 meter zones along the east side of the south porphyry. Of 13 samples collected, all were greater than 100 ppb and with 5 greater than 1 gm/t (3 greater than 2.5 gm/t with a high of 3.8 gm).
  3. Other anomalous zones of gold mineralization in the area include:
    1. Six samples collected across a 100 m zone in the western margin of the property - 5 were anomalous with three giving values of 6.1, 12.3 and 3.7 gm/t gold. One kilometer to the north a sample gave 11gm/t associated with specular hematite.
    2. High-grade gold values to 200 gm/t associated with isolated quartz-pyrite-tourmaline veins to the east of the south porphyry. Gold values of 200 and 128 gm/t were obtained from separate veins.
    3. Gold to 3 gm/t associated with veins along the east side of the middle porphyry.
    4. Gold to 8.8 gm/t associated with quartz carbonate veins along the southwest part of the area.
    5. Gold to 48 gm/t associated with quartz, tourmaline, and sericite altered greisen breccias.
    6. An 11 gram gold sample from quartz (pyrite and specular hematite) veins north of (3) a.

These values are pulled from a 2003 report by Dr. T.A. Richards and Ron Bilquist. The cover photo is of the Las Burras prospect. The small ridge in the foreground hosts anomalous gold values.Cascadero hopes to continue exploration of Incahuasi in the 2017-2018 field season. Incahuasi is jointly owned by Cascadero and parter Regberg.
