Cerro Marquez


Cerro Marquez represents a bulk tonnage, porphyry copper (gold-molybdenum) Opportunity.

Location & Infrastructure Located in the Andes, in the northern part of Chile, region XV of Arica, 80 km south of the Peru border line and 100km SE from Arica port, accessible by paved highway A31 and dirt road. The project is 15 km south from the Ticnamar town, which has basic infrastructure and an electrical grid power.
Property Description 7,800 hectares total, consisting of seven older mineral concessions, on which Endeavour holds an option to purchase a 100% interest subject to a 2% NSR, and 20 new mineral concessions staked by Endeavour. The Company can acquire the 7 historic concessions by spending $1.53 million on exploration and paying $2.5 million over 4 years with the final payment due in 2020. Each 1% NSR can be purchased within three years of commercial production for $1.25 million.
Geology 6.5 x 3 km pervasive alteration with hydrothermal breccias, "D vein“ and qz-hem stockworks and silica ledges. Multiple porphyry intrusion dating in 9.8±0.1 Ma (K-Ar).
Geochemistry Endeavour collected and analyzed 150 rock samples and 1,091 soil samples to define two targets. Rock samples assayed up to 425 ppm copper, 320 ppm molybdenum and 50 ppb gold. Soil samples on the main target defined a 2.6 km long x 1.3 km wide molybdenum anomaly within a 4.5 km x 3.0 km copper anomaly, with gold-arsenic-lead-zinc anomalous throughout. Second and third geochemical anomalies lie along trend to the southeast.
Magnetic & IP Resistivity Geophysics Ground magnetic survey shows a main northwest magnetic trend with secondary east-west and north-south trends. The main target sits within a magnetic low and the second target lies on a magnetic high, suggesting at least two phases of intrusions and/or alteration. Second and third magnetic anomalies lie along trend to the southeast. Five IP-resistivity lines conducted in two phases show classic chargeability highs flanking or coincident with resistivity lows, also coincident with the magnetic and geochemical anomalies and high temperature clays and sericite.
Potential Multiple targets to discover bulk tonnage porphyry orebodies for open pit mining. The main target is 2 km x 1.5 km located in the central area associated with soil and rock geochemical anomalies in Mo-Au-As-Pb as well as copper, white mica (sericite) and a strong IP chargeability anomaly. The age of Cerro Marquez is similar to Chilean biggest porphyries copper “El Teniente”, “Rio Blanco-Los Bronces” and “La Alumbrera” in Argentina.
