Challenger Announces Completion of Hualilan Toll Milling Pre-Feasibility Study

PFS outlines robust economics from toll milling delivering forecast EBITDA of A$221m1 over the 3 years of tolling at current prices

Challenger Gold Limited (ASX: CEL) ("CEL" or the "Company") is pleased to provide the outcomes of the Toll Milling Pre-Feasibility Study (“PFS”) completed on it’s 100% owned Hualilan Gold project located in San Juan, Argentina. The study presents a technical and economic evaluation of the Tolling scheme proposed for the project in conjunction with Austral Gold (ASX: AGD) (“Tolling Partner” or “Toll Mill”) as announced in an ASX Release on 10 January 2025.


Highlights

Toll Milling Pre-Feasibility Study (PFS) delivers compelling financial metrics:

  • Robust margins on conservative commodity prices: using US$2,500/oz Au and US$27.50/oz Ag, the three-year toll-milling plan generates EBITDA of US$88.0M, post-tax NPV5 of US$50.5M, and cumulative post-tax free cash flow of US$56.7M.
  • Leverage to spot prices: at today’s ~US$3,300/oz Au and US$33/oz Ag, EBITDA rises to US $142.8M and post-tax NPV5 to US$82.2M, with post-tax free cash flow of US$91.8M.
  • Low upfront capital and quick payback: total upfront spend is just US$8.9M (A$13.8M) which is US$4.2M upfront capex and US$4.7M working capital, and achieves payback by December 2025 (or 3 months from the commencement of mining).
  • Competitive cost structure: forecast All-In Sustaining Cost ("AISC")2 is ~US$1,454/oz AuEq, comfortably below spot prices and achievable thanks to toll milling and a short haulage distance.
  • Financing risk removed: recent A$33.9M equity placement fully funds development through to first cash flow and acceleration the development of the larger stand-alone Hualilan development.
  • Significant upside: Toll Milling is based on extracting only 3% of the 2.8 Moz Hualilan MRE.

Key operational findings of the PFS for Toll Milling to support

  • High grade reserve-only schedule: mining focuses on three shallow open pits producing 465,000 wet metric tonnes ("wmt") of mineralized material above the cut-off grade at an average mined grade of 6.2 g/t Au and 35 g/t Ag; Inferred Resources are excluded.
  • Payable Metal: Production Target of 76.6 koz payable Au and 338.5 koz Ag over a 30-month processing campaign.
  • Low strip ratio: total material movement of 3.27 Mt with a life-of-mine strip ratio of 6:1 w:o and a forecast mining cost of US$8.12/t.
  • Logistics & processing: ore is hauled 165 km on sealed highway to the fully-permitted Casposo plant, where recoveries are expected at 84.4% Au and 65.7% Ag; all-in processing, haulage and access charges of ≈ US$133/t processed.
  • Campaign rhythm: Casposo batch treats Hualilan ore at ~25 kt/ month, running three months- on/ three months-off, with the toll program spanning 33 months in total.

Harvest Gold CEO Outlines Strategic Play in Québec’s Gold-rich Abitibi Region

Harvest Gold (TSXV:HVG) President and CEO Rick Mark believes the company has a strong position in Québec's Abitibi greenstone belt, emphasizing the highly prospective Urban-Barry belt, "a very well-known mine-producing belt."

In an interview with the Investing News Network, Mark also honed in on Québec's supportive mining environment and accessible properties, which keep exploration costs "relatively very inexpensive."

“The exciting thing about the Urban-Barry belt is it contains a (gold) deposit called Windfall, which Gold Fields (NYSE:GFI) just bought from Osisko Mining,” Mark noted. “Now, the interesting thing about that as well is that the belt itself is basically owned by Gold Fields, except for the three large properties that Harvest Gold has in the belt.”

Satellite Imagery and Gold Exploration

Exploring for gold is a costly endeavor that often comes with great risks, especially for junior mining companies.

These small-scale companies are faced with the challenge of locating a metal that is extremely rare, and even if they do find it, they need to ensure gold is present in economically viable quantities.

That’s where the use of satellite imagery and remote sensing comes in. Using satellite systems scanning for gold helps explorers survey land without having to invest heavily in equipment or develop on-site infrastructure.
