Project overview and resource growth
El Zorro Gold Project in northern Chile has grown to 1.8 million ounces constrained, 2 million ounces unconstrained after a 20,000m drill campaign.
Updated mineral resource estimate announced in May added 500,000 ounces; 60% of resources now indicated.
Deposit remains open in all directions, with high-grade zones at depth and strong potential for further growth.
Average grade is 1.07 g/t gold unconstrained, with 5,000 ounces per vertical metre, supporting attractive open-pit mining.
Near-term exploration targets within 5 km of Tenera, including Pena Blanca, show strong potential for additional discoveries.
Technical and operational highlights
Metallurgy shows over 94% gold recovery at a coarse grind size, with 40% gravity recovery and low cyanide use.
Processing uses wastewater from a nearby desalination plant, with proven compatibility and no interference with gold recovery.
Project benefits from proximity to coast, Pan-American Highway, power, and water infrastructure, with MOUs in place.
Region 3 is a mining-rich jurisdiction, supporting project development and permitting.
Financials and development timeline
Scoping study (June) based on $2,750/oz gold price, 3Mtpa throughput, 14-year mine life, and $1,200/oz AISC.
Post-tax NPV (7.5% discount) is $663M, with $250M upfront capital including $40M pre-strip.
At current gold prices, NPV rises to $1.3B and IRR to 85%; robust even at $2,300/oz gold with $400M NPV.
Fully funded through feasibility (end 2026) and aggressive exploration, with Gold Fields holding a 13% stake.

One of the very few apps you could call perfect. If something was to add to it, maybe the share price of the company when you search for it, but it's already excellent.
