Environmental and Financing Hurdles Loom as Flagship Advances Pantanillo Gold Project
Flagship Minerals has commenced a comprehensive review of a vast dataset acquired from Anglo American for its Pantanillo Gold Project in Chile, confirming a large oxide gold system with exceptional drill results. This positions the company to fast-track a JORC-compliant Mineral Resource Estimate and advance towards production.
- Acquisition of over 700 files and 100 tonnes of core from Anglo American
- Confirmation of a 1.05 million ounce foreign gold estimate with potential for growth
- Multiple broad, high-grade drill intersections including runs exceeding 100 gram-meters
- Plans to convert foreign estimate into JORC Mineral Resource and advance metallurgical studies
- Targeting open pit mining and heap leach processing for 100,000 ounces gold production annually
A Game-Changing Dataset Acquisition
Flagship Minerals Limited (ASX – FLG) has taken a significant step forward in its pursuit of gold production with the acquisition and initial review of an extensive dataset from Anglo American Norte SpA. The Pantanillo Gold Project in Chile, situated in the prolific Maricunga Gold Belt, now benefits from over 700 files containing more than 10,000 documents, alongside an impressive 100 tonnes of drill core, pulps, and samples. This trove of information provides Flagship with a robust foundation to validate and expand upon a previously reported 1.05 million ounce foreign gold estimate.
Exceptional Drill Intercepts Confirm Scale and Grade
Re-examination of the drill data reveals multiple broad intervals of gold mineralisation, with some intercepts stretching beyond 300 meters at grades exceeding 0.5 grams per tonne. Noteworthy highlights include 116 meters at 1.5 g/t and 142 meters at 1.13 g/t gold, underscoring the deposit's potential as a large-scale oxide system amenable to heap leach processing. The top 20 drill intersections average an impressive 205 meters at 0.65 g/t gold, reinforcing the project's scale and grade continuity.
Towards a JORC-Compliant Mineral Resource
Flagship is now focused on converting the qualifying foreign estimate, originally reported under Canadian NI 43-101 standards, into a Mineral Resource Estimate compliant with the JORC Code (2012 Edition). This process involves rigorous validation of drillhole data, re-sampling of core where necessary, and updated geological modelling. The company anticipates that leveraging the comprehensive dataset and applying updated cut-off grades and economic parameters will enable resource growth without the immediate need for additional drilling.
Strategic Development and Production Outlook
The Pantanillo project strategy targets open pit mining combined with heap leach processing, aiming to produce approximately 100,000 ounces of gold annually over a decade. Metallurgical testwork supports the feasibility of heap leach recovery, with gold recoveries estimated at 75% for oxide material. Flagship is concurrently advancing technical studies and environmental permitting, mindful of the project's proximity to environmentally sensitive areas such as the Nevado Tres Cruces National Park and Ramsar sites.
Funding and Next Steps
To support the next phase of resource conversion and project development, Flagship is in discussions to raise approximately $3 million through an equity placement. This capital will underpin further technical validation, metallurgical testing, and potential infill drilling. The company’s Managing Director, Paul Lock, emphasised the transformative nature of the Anglo dataset acquisition, positioning Flagship well amid rising global gold prices and increasing investor interest in advanced-stage gold projects.
Bottom Line?
Flagship Minerals’ meticulous data review and resource upgrade efforts at Pantanillo set the stage for a pivotal transition from exploration to development in a rising gold market.
Questions in the middle?
- How soon can Flagship convert the foreign estimate into a JORC-compliant Mineral Resource?
- What impact will environmental permitting near protected areas have on project timelines?
- Will additional drilling be required to further expand the resource or confirm higher-grade zones?
