Anocarire Project
The Anocarire Project is located in the district of Putre, Province of
Parinacota, Region I, Chile, approximately 120 km east of Arica and 60
km southeast of the town of Putre.
The exploration that has been conducted to date at Anocarire has
generally defined a north-westerly trending structural zone which has
defined the emplacement of the original partially eroded Tertiary
stratovolcano and which has controlled the emplacement of the very high
level, steam-heated (advanced argillic) alteration and coincident
variously weakly anomalous mineralization. The steam heated zone is
characterized by variably friable and porous to massive opaline silica,
gypsum, jarosite, limonite, and weakly developed native sulfur, with
flanking and/or below, zones of argillic and advanced argillic
alteration including areas of quartz-(kaolinite) alunite. The
north-westerly trending zone of the very high-level alteration is
estimated to be approximately 900 m long by 600 m wide. The host rocks
for the alteration/mineralization are considered to be andesitic
volcanics.
Andina drilled two holes for the purpose of determining the nature of
the geology underlying the widespread high sulphidation-type epithermal
alteration system. Drill hole DAN-01, drilled to a depth of 286 metres,
returned elevated gold values averaging 0.06 grams per tonne gold over
the bottom 106 metres of the drill hole along with elevated barium and
mercury values. Drill hole DAN-02, was lost at a depth of 117 metres as
a result of poor ground conditions, however, anomalous gold values were
obtained.
Previous to that, Homestake Mining collected a series of surface samples
1997 and Goldfields also did limited work (2004) taking 102 rock chip
samples. |
