Challenger Gold (ASX:CEL) has laid out a development roadmap for its Hualilan gold project in San Juan, Argentina, targeting first commercial production from a Phase 1 heap leach operation by early 2029. The announcement, filed with the ASX on 10 September, gives investors a clearer picture of how one of the sector’s larger offshore development stories plans to move from resource to revenue, backed by a pre-feasibility study that puts the project’s post-tax value at roughly US$1.1 billion.
A Staged Path to First Production
The plan calls for a phased build, starting with a standalone heap leach circuit before a flotation plant is added around two years later. That staging keeps pre-production capital to about US$267 million, a meaningful saving versus a single stage build. At a US$3,500 per ounce gold price assumption, the study points to a 35 percent post-tax internal rate of return and a payback period of just over two years, figures that look stronger given gold’s push toward record highs this year. Over a mine life of more than 14 years, Hualilan is expected to average 135,000 ounces of gold equivalent annually.
Drilling and Financing Milestones Ahead
Challenger Gold is running a 35,000 metre drilling campaign across four rigs, a program similar in scale to the recent push at Barton Gold’s Tunkillia project in South Australia, aimed at growing the resource ahead of a technical report due in early 2027. On funding, the company is working to refinance a US$15 million convertible debenture maturing this month, has flagged an application under Argentina’s RIGI investment incentive scheme for the December quarter, and is exploring a secondary listing to widen access to international capital, a push that echoes the scale of recent gold sector dealmaking such as the Genesis Minerals and Vault Minerals merger.
What It Means for ASX Gold Investors
For shareholders, the update trades near term production for a clearer, fully costed pathway at a project with genuine scale, a rarity among ASX listed developers with South American assets. With gold prices sitting near record highs, the economics behind large, long life projects like Hualilan look more resilient than they would have a few years ago, though execution risk around financing, permitting and construction timelines in Argentina remains the key variable to watch.
