Highlights
- Arrieros is a reduced property (900 hectares) from an originally larger project area, completely obscured by extensive post- mineral alluvial “pampa” cover
- Arrieros comprises a 3D Vector-IP chargeability anomaly in an area of post- mineral alluvial “pampa” cover
- Located adjacent to a series of historically drilled porphyry targets
- Located along world’s preeminent Domeyko Cordillera copper belt in northern Chile
- Supported by multiple magnetic features in Arrieros pampa, possibly related to a batholithic intrusion at depth
- Geology equivalent to major porphyry copper districts along belt
- Middle Eocene to Early Oligocene age dated porphyry systems historically drill tested to the immediate west of Arrieros (at Montezuma project)
Regional Geology
- The Domeyko Cordillera mineral belt is a relatively narrow, north-south anastomosing fault zone with a complex structural history over + 600 km of the northern Chilean Andes, and includes uplifted blocks of Paleozoic to Mesozoic rocks and fault-controlled porphyry-related Tertiary magmatism
- Key Incaic deformation phase (~ 43Ma – 32Ma) associated with Middle Eocene to Early Oligocene magmatic arc, resulting in the emplacement of some of the world’s largest porphyry copper deposits and the development of the world’s single most productive porphyry Cu belt
- Including: Chuquicamata District: > 800 Kt fine Cu / year – Centinela: > 250 Kt fine Cu / year
- Local geology dominated by Miocene, gravel filled “pampa” basin, bordered by uplifted Paleozoic rocks and dated, mineralized, porphyry intrusions immediately to the west
Access
Location
Arrieros is located approximately 22 km south-southeast of the mining town of Calama and 192 km northeast of the port of Antofagasta, and directly along trend and midway between the Chuquicamata and Centinela copper mining districts in northern Chile
Access
Access to the property is easy, from Calama, via a series of dirt roads that skirt the Calama airport, and pass directly along the famous West Fissure Fault Zone, until the project area is reached
Other Details
3D-VIP Map – Phase Angle – of Arrieros Project Area (Blue Box)
- The extensive post-mineral covered alluvial filled “pampa” area that comprised the original Arrieros project (> 14,000 hectares) was targeted due to geographic location in relation to major mines and drilled porphyry projects
- Property subject to: Drone-flown magnetics surveying & 3D-VIP surveying
- Multiple magnetic features of prospective interest in northern half of Arrieros property/li>
- Cu-oxide occurrences on northern margins of Arrieros pampa
- Property reduced in size to 900 Ha based on IP results
- Two historic drill holes to immediate south of anomaly, failed to reach bedrock (250m)
- Drill tested porphyry targets sub-cropping to immediate west of Arrieros property (historic Montezuma project)
