Lukkacha Project Old

Lukkacha is located in the Tacna Region in southern Peru. The property lies 60kms northeast of the city of Tacna, Peru and 9 km southwest of the town of the supply town of Tarata. The property is 50 km southeast from the operating Toquepala Mine of Southern Copper Corp.

Lukkacha Project Highlights

  • Along southern Peru’s copper belt.
  • Characteristic alteration, geochem and structure of major system.
  • Large-scale tonnage potential.
  • A classic porphyry-copper target

Location Map

The property consists of 4400 hectares in 7 concessions owned by Rustica Claudia, S.A.C., a private Peruvian company.  Miramont has a four year option to acquire 100% of the property.

The property is accessed year-round via paved and all – weather roads. Nearby city of Tacna is served with regular commercial air service from Lima. Access is excellent on paved and all-weather roads and water for exploration work is readily available from a nearby source.

Porphyry Copper Model

Regionally, Lukkacha is located along the trend of Peru's largest copper deposits of Cerro Verde, Cuajone, Quelleveco and Toquepala, a northwest-striking belt of copper deposits aligned near the Incapuquio fault.  The property is underlain by Tertiary volcanics of the Toquepala Formation (the same host rock to the Toquepala Mine). These rocks represent a late Cretaceous to Paleogene volcanic arc. This volcanic sequence has been intruded by a complex system of quartz diorite, dacite, and granodiorite stocks and dikes.

A large halo of propyllytic alteration is found surrounding a core zone of approximately three square km with phyllic alteration. This is coincident with copper and molybdenum geochemical anomalies. Tourmaline matrix dikes are also prevalent. This alteration is typical of productive porphyry Cu systems, has well-developed stockwork veining and is interpreted to be the upper halo of a major mineralizing system.  The intensity of stockwork veining and sheeted veinlets is very strong and indicative of a well-developed system.  Zones of sheeted veins many 10’s of meters wide strike ENE, a common mineralized trend in this part of Peru.

The geologic setting at Lukkacha is similar to the nearby Toquepala mine complex (Southern Copper Corp.), one of Peru's largest copper mines. This provides clear exploration models for Miramont’s planned program.

Reconnaissance at Lukkacha has revealed that the property encompasses a large, zoned system of hydrothermal alteration typical of similar porphyry copper deposits. The primary target covers approximately three square km. A detailed mapping and sampling program will be conducted over the project area. This basic geologic work coupled with a subsequent geophysical program will lead to the development of drill targets. 

The combination of the exceptionally-strongly developed stockwork and sheeted veins, with a multi-phase intrusive center, and a clear geochemical anomaly, indicate that the property has excellent potential to host significant Cu mineralization. Nearby copper deposits are often characterized by leached outcrops and a supergene enrichment zone developed below surface. These enrichment zones can present higher-grade copper deposits than primary ores. Lukkacha exhibits many characteristics of leached outcrops and so a copper enrichment zone will be a focus of exploration.

Lukkacha regional

The Lukkacha project lies 36 kilometers from the Chilean frontier. As such it is within a 50 km foreign-border zone in which the Peruvian government requires non-Peruvian owners to demonstrate a public necessity before operating approval can be granted. This applies to mining projects in addition to many other industrial or agricultural activities. Final permission is granted by a Supreme Decree of the Peruvian executive. Miramont has started the application process
