Fredonia puts numbers on El Dorado Monserrat gold
A preliminary study pins EDM at US$1.49B NPV10 and 65% IRR — on aggressive prices, preliminary metallurgy, and a third Inferred rock.
Fredonia Mining released a Preliminary Economic Assessment for its El Dorado Monserrat gold-silver project in Santa Cruz, Argentina, on August 31, 2026. A PEA is an early, rough sketch of whether a deposit could make money — not a construction blueprint. The headline figures: 146,000 ounces of gold-equivalent a year, a US$1.49 billion net present value at a 10% discount rate, and a 65% internal rate of return (the annual return the project would earn if everything went to plan). The market noticed. FRED shares ran up 32.8% over three months while gold barely moved (+0.5%) and the junior gold index gained a modest 11.2% — Fredonia tripled both. The sparkline shows a deep trough mid-period then a sharp, sustained climb, the classic fingerprint of a company-specific catalyst rather than a rising tide.
Here’s the mechanism. EDM is a large, near-surface, low-grade system. The plant feed classed as Measured and Indicated (the more reliable buckets) runs 79.67 million tonnes at 0.606 grams of gold per tonne — about six-tenths of a gram, or roughly one-fiftieth of an ounce, in every tonne of rock. Scale, not richness, is the pitch: 2.76 million gold-equivalent ounces in M&I plus another 1.09 million Inferred. The company plans to heap-leach the ore — stack crushed rock and trickle chemistry through it — at an assumed 85% gold recovery. Cash cost lands near US$1,630 per ounce, which is high, so the margin lives or dies on the gold price. The board added Constantine Karayannopoulos in May 2026, co-founder of Neo Lithium (sold for about US$960 million), though his track record is rare earths and lithium, not gold heap-leach.
Now the honest part. This is a PEA and resource release, not drill results — there are no intercepts or true widths to weigh. The economics lean on very high assumed prices: US$3,800 per ounce gold and US$45 silver for the mine plan, US$4,000 and US$70 for the resource math. Roughly 36% of the scheduled feed is Inferred Resources, explicitly too speculative to count as reserves; no Mineral Reserves have been declared. The 85% recovery rests on initial bottle-roll testwork only, and the company says more representative metallurgy is required. QA/QC and QP independence aren’t stated in the release. Next up: an ongoing 10,000-metre infill and exploratory drill program from September, metallurgy and permitting surveys targeted for Q1 2027, and PFS/FS-level studies through 2027.
