Los Loros

Los Loros Project - A Compelling Copper Porphyry Target

Los Loros sits within the Early Cretaceous Coastal Cordillera porphyry belt, hosting several operating mines and large undeveloped deposits, including Carmen de Andacollo mine, Costa Fuego and Llahuín deposits. These analogues demonstrate the scale and potential longevity of porphyry systems in this belt.

Key attributes that elevate Los Loros as a standout exploration opportunity include:

• Porphyry mineralisation exposed at surface, significantly reducing exploration risk and drilling depth requirements
• Demonstrated copper, molybdenum and gold endowment, confirmed by historical drilling
• High-grade gold epithermal mineralisation overprinting the porphyry 
• Large alteration footprint (~800m x 300m) consistent with a sizeable porphyry system
• Proximity to infrastructure: 30 km to port, 20 km to La Serena, sealed road access to foothills
• Low altitude (~500m), with the Los Loros project accessible all year round

This combination provides multiple value drivers within a single project: bulk-tonnage Cu-Mo potential at depth and structurally controlled, high-grade gold zones closer to surface.

Why Was Los Loros Historically Underexplored?

Despite being recognised as a porphyry system as early as the 1970s, Los Loros has never been systematically explored using modern techniques. Historical work was episodic, shallow and commodity-price driven, with most drilling focused on near-surface copper oxide zones suitable only for small-scale mining.

Historical Exploration

The Los Loros Porphyry was recognised as a porphyry in the 1970s. This led to relatively minor episodic exploration activities over the area over the last six decades. Exploration included soil sampling, geophysics and drilling campaigns.
A total of 36 drillholes (RC and DDH drilling) for a total of 4,911 meters were drilled over the project area, with most of the drillholes shallower than 150m depth, targeting copper oxides close to surface.

Only 14 drillholes are above 150m depth, and only 6 of them were targeting the Los Loros porphyry. The only geophysical survey was an IP survey completed in 1969 in the south of the Project.
