Challenger Gold Ltd. has released a disciplined development pathway for its Hualilán gold project in Argentina, backed by an AU$85 million equity placement and key executive appointments led by mining veteran Peter Marrone as Non-Executive Chairman.
The developer is pivoting away from a small-scale third-party toll treatment model toward a fully integrated, on-site mining and processing operation in San Juan Province.
An operational review confirmed that the orebody’s broader, disseminated mineralisation is better suited to large-scale open-pit mining rather than selective underground extraction.
During a four-month transition, Challenger aims to replace its toll-treatment structure with an ore purchase agreement with Casposo, reducing direct processing cost risks while maintaining near-term cash flow.
The strategy aligns Hualilán with its recently completed pre-feasibility study (PFS), which outlined a 14.25-year mine life producing 1.84 million ounces of gold equivalent.
Operating at an average of 135 thousand ounces per year, the project carries a post-tax net present value of US$1.10 billion (AU$1.65 billion) at a US$3,500 per ounce gold price, alongside an all-in sustaining cost (AISC) of US$1,618 per payable ounce. Upfront capital is estimated at US$232 million, featuring a rapid 2.25-year payback.
The AU$85 million capital raise, supported by institutional investors and Marrone, will fund project engineering, feasibility updates, and a minimum 35,000-metre diamond drilling campaign, marking Hualilán’s first exploration program in over three years.
The drilling will target resource extensions, support open-pit conversion, and provide geotechnical data for a proposed Phase 1 standalone heap leach development.
Challenger Gold stated that the operational reset and corporate refresh position the company to capture long-term asset value.
“Hualilán remains a high-quality gold development opportunity with the potential to become a meaningful, long-life operation,” the company said.
“The published PFS demonstrates the scale of the opportunity, including a 1.84Moz AuEq production target, a 14.25-year mine life, low upfront capital intensity, a competitive AISC profile and significant NPV leverage to the gold price environment.”
The company’s near-term focus is to maximise cashflow through the current operational transition, apply the lessons from early mining activity and accelerate the work required to position Hualilán for its next major phase of development.
