Altiplano reports evidence for a second stage of mineralization potential for porphyry-type discovery at Farellon
Altiplano reports evidence for a second stage of mineralization potential for
porphyry-type discovery at Farellon
EDMONTON, June 26, 2018 /CNW/ - Altiplano Minerals Ltd. (APN: TSXV) (ALTPF: OTCQB) (9AJ1: GR)
("APN" or the "Company") is pleased to report evidence for a second stage of mineralization at the
historic Farellon Copper Gold Mine ("Farellon") near La Serena, Chile.
CEO John Williamson stated, "We are excited to have discovered evidence suggesting the occurrence of
a second stage of Cu mineralization at Farellon. Evidence for this new form of mineralization is indicated
by chalcopyrite infilling microfractures in porphyritic andesitic dikes that crosscut the Farellon vein; weak
potassic alteration observed in those dikes; and breccia fragments of the vein cemented by a mineralized
magmatic rock observed in the NE395M level. In addition, non-linear magnetic anomalies identified with
ground geophysics may indicate the presence of porphyry-type mineralization postdating the IOCG veins.
This increases substantially the economic potential of the district. The Company will commence academic
studies and additional fieldwork studies, including microscopic analysis of both mineralization and host
rocks; trace elements and whole rock geochemistry; and radiogenic dating of magmatic rocks and
mineralization, aimed at gaining a better understanding of the mineralizing processes within the district.
Exploration for both IOCG veins and porphyry-type mineralization will continue at Farellon".
Surface and underground mapping have helped to elucidate the crosscutting relationships between
different magmatic units and IOCG veins (Figure 1).

The main IOCG veins are hosted by a diorite–granodiorite with phaneritic texture and less importantly, by
a recrystalized andesite that shows a range of textures including magmatic breccia textures. The IOCG
veins are crosscut by porphyritic andesitic dikes that occasionally show minor potassic alteration (shreddy
biotite disseminated in the matrix) and dissemination of chalcopyrite controlled by fractures (Figures 1
and 2a). This evidence opens the potential to find porphyry-type copper mineralization overprinting IOCG
veins within the Farellon and neighbouring properties. Non-linear magnetic anomalies roughly correlate
with surface outcrops of porphyritic andesite and may indicate mineralization at depth. This assumption is
supported by the fact that the Andacollo porphyry copper-gold deposit is located only 12 km southeast of
the Farellon property. Additionally, the Farellon vein shows evidence of post-mineralization tectonic
deformation and brecciation cemented by a magmatic rock (possible diorite) with dissemination of
chalcopyrite (Figure 2b). This evidence is observed at the NE395M level where the vein expands up to 8
m wide and indicates that the widening of the vein was caused by geological processes post-dating the
IOCG vein formation. Presently, APN has developed ~30 m within the wider zone with an average grade
of 1.72 % Cu (Figure 3).
