Challenger Gold Secures Toll Milling Deal with Casposo Argentina Mining

Challenger Gold has successfully finalized a binding toll mining agreement with Casposo Argentina Mining, ensuring a processing capacity of 150,000 tons per year (tpa) for the next three years. The deal guarantees a total processing capacity of 450,000 tons over the duration of the agreement, with Challenger Gold investing significant working capital to cover mining, trucking, and processing expenses until it begins generating cash flow.
Key Details of the Agreement:
- The toll processing fee is set at US$8.80 per ton, with a minimum monthly payment of US$110,000.
- An upfront payment of US$2 million is required, with another US$1 million due in the second year of the agreement, amounting to US$6.67 per ton.
- A performance-based fee of 20-30% of milling costs will be paid, depending on recovery rates, and is expected to range from US$12 to US$18 per ton.
- The upfront payment will be refunded if the plant does not start operations by July 31, 2025.
Alongside this, Challenger Gold is making progress on a strategic $6.6 million investment, with the subscription agreement terms now finalized.
Argentina’s Growing Appeal for Mining Investment
Under the leadership of President Javier Milei, Argentina is quickly becoming a hotspot for mining investment. Milei’s market-driven approach and efforts to reduce mining restrictions have created a buzz in the industry. Challenger Gold’s Hualilan project in San Juan, which includes gold, silver, and zinc, is one of the largest resources on the ASX, with an estimated 2.8 million tons of gold equivalent.
The diverse mix of metals in this project means it stands to benefit from the rising prices of both precious and base metals. As of Wednesday, gold remained above US$2640 per ounce, marking an increase of 28.45% since the start of the year.
Path to Production
Challenger Gold remains dedicated to advancing key operations to initiate toll milling. Over the coming months, the company will finalize operational processes with the mill operator to ensure the smooth implementation of the toll milling agreement, expected to take place within the next 15 to 20 days. Additionally, mining designs and schedules are set to be completed in the coming days, with evaluations of contract mining and owner-operated options continuing.
This structured approach to production ensures both flexibility and financial responsibility as the company moves forward with its operations in Argentina.
