Arcas Generative Project (Chile)
Arcas is a 55,000 hectare project focussed on generation of prospective copper porphyry targets located along the Domeyko Fault System at the core of Chile's prolific Paleocene and Eocene-Oligocene porphyry belts. The project is currently comprised of four groups of claims strategically located between the El Abra and Collahuasi clusters in northern Chile. Very limited exploration work has been carried on the projects historically while ongoing work by Altius indicates the existence of 4 distinct porphyry (and associated epithermal) targets that merit further exploration.
Arcas: Ongoing prospecting and mapping of the property has so far identified four porphyry-related targets. Of these, one has been historically drilled (1,500 metres total, 350 m maximum depth) with porphyry-style copper-gold mineralization demonstrated. Rock sampling of the other three target areas includes grab samples up to 1% Cu and 0.7 g/t Au. Alteration assemblages and mineralization on the new target areas indicate that they are closely associated to a long-lived (and active) fault system with approximately 5 km of vertical displacement. Re/Os age determinations on molybdenite is currently underway in order to determine the timing of porphyry emplacement within the structural framework. Long-lived multi-stage magmatic-hydrothemal systems are typical of the major copper deposits in the region.
Quiltro: Epithermal features defined with ASTER reprocessing and confirmed during recent ground follow up prospecting. Au anomalies up to 153 ppb are related to brecciated veins with pervasive hematite alteration.
Lia: Outcropping dacitic porphyry with sericite/Chlorite/Clay assemblages cut by quartz-hematite veinlets and quartz-diorite porphyry that intrudes Paleozoic volcaniclastics resembling a Skarn type alteration. Notably certain distinctive tabular units within the geological sequence have returned encouraging results of > 1% Cu, 562 ppb Au, 25 ppm Ag, 399 ppm Mo, 2129 ppm Pb and 1710 ppm Zn in grab samples.
Timón: Argyllic and propyllitic alteration zones related to granidioritic and dioritic intrusives were noted by a previous operator. Locally, veins and fractures with Cu-oxides assaying up to 2.6% Cu and 34 ppm Ag have been documented. N-S faults appear to control the location of the alteration zones, and correlate well with high magnetometry anomalies.
Altius is seeking partners to advance each of these projects in this prolific copper district. Additional technical information is readily available by contacting Chad at firstname.lastname@example.org.
