Lodestar Minerals has taken a strategic step into Chile’s prolific copper belt by acquiring the Pacifico Cu-Mo-Au Porphyry Project, consolidating over 22 square kilometres of tenure with a rich historical drilling record. The company plans maiden drilling in the second quarter of 2027, aiming to unlock potential along a six-kilometre porphyry corridor.
- Option agreement covers 22 km2 over a six-kilometre porphyry corridor
- Historical drilling totals more than 8,000 metres with significant Cu-Mo-Au intercepts
- Central target area remains untested and newly identified by Lodestar
- Staged option payments up to USD 4.3 million plus 1.5% NSR royalty
- Maiden drilling planned for Q2 2027 funded from existing cash reserves
Strategic Entry into Chile’s Paleocene Copper Belt
Lodestar Minerals (ASX:LSR) has snapped up the Pacifico Project, a copper-molybdenum-gold porphyry exploration package in Chile’s Atacama Region, through an option agreement with Minera Bornita. The acquisition consolidates a contiguous tenure of approximately 22 square kilometres spanning a six-kilometre prospective porphyry corridor, historically explored in fragmented northern and southern blocks.
The Pacifico Project sits just 42 kilometres south of the world-class Relincho deposit, jointly owned by Teck Resources and Newmont, which boasts over a billion tonnes of copper reserves. This proximity places Pacifico within a globally significant Paleocene metallogenic belt, home to giants like Sierra Gorda, Cerro Colorado, and Spence, underscoring the regional copper endowment.
Robust Historical Drilling Dataset Provides a Solid Foundation
Historical exploration at Pacifico, conducted by First Quantum Minerals and Hudbay Minerals between 2016 and 2020, includes 16 diamond drill holes totalling over 8,000 metres. These campaigns intersected multiple porphyritic intrusions with copper and molybdenum mineralisation, including intervals grading up to 0.67% copper and 817 ppm molybdenum, with copper equivalent grades reaching 1.03% over short intercepts.
Notably, mineralisation extends from near surface to depths exceeding 700 metres, with continuous downhole intervals of copper-molybdenum mineralisation identified. However, the historical data, compiled from TSX-listed explorers’ reports, does not comply fully with JORC 2012 standards and requires further verification to support resource estimation.
Underexplored Central Target Offers Fresh Upside
Lodestar’s recent reconnaissance uncovered outcropping porphyritic dykes within the central portion of the corridor, an area previously overlooked and never drilled. This discovery opens a new frontier within the project, with plans underway for detailed geological mapping, surface geochemical sampling, and re-interpretation of geophysical surveys to prioritise drill targets.
The company’s CEO Coraline Blaud highlighted the strategic value of consolidating the corridor into a single project, enabling a systematic evaluation of the geological and geophysical data to refine exploration efforts. This approach complements Lodestar’s existing Chilean copper portfolio, which includes the Los Loros and Three Saints projects.
Option Agreement Terms and Exploration Plans
The option agreement allows Lodestar to acquire the five exploration licences over five years through staged payments starting with a modest US$30,000 upfront, escalating to a US$3 million exercise payment, plus a 1.5% net smelter return royalty payable to Minera Bornita. Lodestar will fund all exploration and governmental costs during the option period.
Looking ahead, the company aims to integrate historical drilling, geophysical data, and new surface mapping to define high-priority targets for a maiden drilling campaign targeted for the second quarter of 2027. This program will be financed from existing cash reserves, reflecting Lodestar’s measured approach to advancing the project.
Geological Setting and Regional Context
Pacifico lies at the margin of the El Carrizo batholith, with a hydrothermal alteration footprint extending along the contact with volcano-sedimentary units of the Hornitos Formation. Multiple intrusive phases and associated sulphide mineralisation typical of porphyry copper systems have been identified. The project’s NW-SE structural corridor is interpreted as a potential conduit for mineralisation, though continuity along the full six-kilometre trend remains to be confirmed through further work.
Geochronological data indicate that Pacifico’s mineralising events coincide with the timing of major deposits in the region, adding geological credibility to its prospectivity, though no direct resource equivalence is implied.
Bottom Line?
Lodestar’s acquisition of Pacifico positions it well to leverage Chile’s copper boom, but the untested central target and reliance on historical data mean that the coming year’s drilling results will be pivotal.
Questions in the middle?
- Will maiden drilling confirm the extent and grade continuity of mineralisation along the Pacifico corridor?
- How will Lodestar integrate new geological data with historical datasets to refine exploration targets?
- What impact could evolving copper market dynamics have on the project’s valuation and development timeline?
