Aftermath Silver advances drilling at Berenguela and Challacollo
Aftermath Silver Ltd (TSX-V:AAG, OTCQX:AAGFF, FRA:FLM1) told investors that it is advancing drilling and development work at its Berenguela silver-copper-manganese project in southern Peru and Challacollo silver-gold project in northern Chile, with a prefeasibility study at Berenguela remaining on schedule for early 2027.
At Berenguela, the company has completed 4,002 metres of its third diamond drilling campaign as of July. The program is targeting untested areas in the eastern and southeastern portions of the known mineralization, upgrading portions of indicated resources, further defining the northern extent of the resource and collecting material for additional metallurgical testing.
The company has begun follow-up drilling at the Copper East target, where previous drilling identified elevated copper and silver grades. Two section lines are planned 50 and 100 metres east of hole AFD139, which returned 69 metres grading 1.19% copper and 78 grams per tonne silver.
Aftermath also plans to begin drilling at the South-West Intrusive target, located about four kilometres from the main Berenguela resource, once one of its drill rigs becomes available.
The company is also completing a nine-hole geotechnical drilling program to support engineering work for the prefeasibility study. Metallurgical testing, hydrogeological work and trade-off studies covering plant throughput, location, reagent supply and infrastructure are also underway.
Aftermath expects the Berenguela prefeasibility study to be completed in early 2027.
The company’s CEO Ralph Rushton noted that the study remains on budget and on schedule.
At Challacollo, Aftermath has completed five diamond drill holes totaling 630 metres, including four targeting the Lolon vein and one on the Lucy vein. The program was initially designed to test extensions of the Lolon vein and its potential south of the existing resource.
The company has now extended the program to 2,000 metres, with drilling moving back to the southern portion of the Lolon vein. The work is intended to test depth and lateral extensions of the main vein and assess the potential of the Lucy vein to the west.
Challacollo’s existing mineral resource estimate contains 35.15 million ounces of silver and 58,000 ounces of gold in the indicated category, along with 11.14 million ounces of silver and 15,000 ounces of gold in the inferred category.
“With key exploration and geotechnical drilling underway we expect a busy next few months at Aftermath,” Rushton said.
“At Berenguela, we are currently doing follow up drilling on the previous high-grade copper intersections in the eastern zone and expect to be drilling the prospective South-West Skarn Intrusive target shortly.”
He added that drilling at Challacollo would be extended as the company continues testing the Lolon and Lucy veins.
