Rio2 Limited has rebounded from a savage Chilean winter at its Fenix Gold mine, where a string of severe snowstorms put the brakes on its first-year production ramp-up.
asserted
string → rebound → up
Despite the weather hampering progress through July and August, the company has kept its processing infrastructure ticking over and says Fenix Gold remains on track to hit commercial production during the fourth quarter.
asserted
Gold → hamper → quarter
Heavy snow and high winds shut down mining from July 17 to 24 and again from August 10 to 22.
asserted
snow → shut → 22
Three significant single-day snowfalls followed.
asserted
snowfalls → follow → ?
Rio2 attributes the extraordinary season to what it calls a super El Niño affecting weather patterns in Chile and Peru.
asserted
it → attribute → Chile
Rio2 says it safely evacuated personnel during the storms.
asserted
it → say → storms
The leach pad, process plant and power generators remained intact and operating at reduced capacity, helping preserve the site for a return to mining.
asserted
pad → remain → mining
With the worst of the weather now seemingly behind it, management is implementing initiatives to claw back lost production.
asserted
management → implement → production
Rio2 is forecasting conditional monthly gold production of 4000 ounces in October, 6000 in November and 7000 in December as a possible path through the final quarter, assuming minimal further disruption.
asserted
Rio2 → forecast → disruption
The storms also forced the temporary suspension of the exploration drilling program at Fenix Gold.
asserted
storms → force → Gold
So far, Rio2 says it’s completed 43 holes for 14,669m of a planned 21,880m program, with plans to resume the remaining drilling in January 2027, during Chile’s summer.
asserted
it → say → summer
The completed holes were designed to test deeper mineralisation up to 100m beneath the reserve pit and within the wider resource pit shell.
asserted
holes → complete → shell
To date, 60 per cent of samples taken have been assayed, with the balance expected within two months.
asserted
balance → take → months
Once all assays are received, the company plans to release the results, then drill further at depth and along the existing resource in the new year, with the findings feeding a revised geological model and an updated resource estimate, slated for Christmas next year.
asserted
findings → receive → Christmas
The Fenix Gold operation is a 100 per cent-owned, high-altitude mine sitting 4500m above sea level in Chile’s prolific Maricunga gold belt, around 160km from Copiapó.
asserted
operation → own → Copiapó
Its low-grade oxide deposit hosts a measured and indicated resource of 389 million tonnes grading 0.38 grams per tonne (g/t) gold for 4.8 million ounces.
asserted
deposit → host → ounces
Its production model is based on a simple run-of-mine heap-leach process, where mined ore is placed directly onto lined pads without a conventional crushing circuit.
asserted
ore → base → circuit
This makes continuous ore movement central to its success, highlighting the impact of storm-related mining pauses.
asserted
movement → make → pauses
Rio2’s 2023 feasibility plan envisaged daily placement rising from 12,000 tonnes in year one to 20,000 tonnes at full base-case capacity, eventually delivering average recovered gold of 91,000 ounces a year over a 12-year mine life.
asserted
placement → envisage → life
Fortunately, Rio2 is no one-trick pony, with its producing Condestable underground mine in Peru packing 36.5 million tonnes of reserves grading 0.73 per cent copper, alongside gold and silver credits.
asserted
mine → produce → credits
The operation is forecast to churn out 18,000 tonnes of contained copper, 12,900 ounces of gold and 304,800 ounces of silver annually at its current 8400-tonne-per-day rate, with a 14-year mine life stretching to 2039.
asserted
operation → forecast → 2039
The race is now on for Rio2 at Fenix Gold to outrun the Andean winter and reach commercial production.
asserted
Rio2 → outrun → production
With core infrastructure safe and a plan to claw back lost ounces, the final quarter of the year will likely be a test of operational grit against the elements.
asserted
quarter → claw → elements
Is your ASX-listed company doing something interesting?
asserted
company → list → something
