Aftermath Silver Berenguela & Challacollo Project Updates
Aftermath advances its PFS and drilling program while awaiting new assay results to impact the project's economic outlook.
Aftermath Silver Ltd. (AAG) released an operational and exploration progress update rather than a new drill-result announcement. The company confirmed that the Berenguela Preliminary Feasibility Study (PFS) remains on schedule and on budget for publication in early 2027 or Q1 2027. Completed work to date includes gap analysis, infill drilling, metallurgical testwork, geotechnical and hydrogeological drilling, and trade-off studies.
As of July 2026, 4,002 m of the third diamond drilling campaign has been completed at Berenguela. Drilling is now testing the Copper East target, with section lines planned 50 m and 100 m east of AFD139. The release repeats historic intercepts: AFD100 returned 156 m grading 1.12% Cu, 290 g/t Ag and 7.3% Mn; AFD139 returned 69 m at 1.19% Cu and 78 g/t Ag; and a bonanza silver interval of 1.95 m at 14,252 g/t Ag. No new assay results are reported from the current Berenguela program.
At Challacollo, five holes have been completed totalling 630 m, four on Lolon and one on Lucy, and the program is being extended to 2,000 m. No new Challacollo assays are provided; the release includes only the prior 2020 NI 43-101 Challacollo resource table.
Aftermath Silver Ltd. (AAG) issued an operational update that does not alter the Berenguela or Challacollo mineral resource estimates, project economics, or recoveries. The Pre-Feasibility Study (PFS) remains on schedule for early 2027.
The stock reached a 52-week high of C$1.31 in January 2026 before declining to C$0.62 by late June 2026. It has since recovered modestly to C$0.81. The market has not aggressively bid the stock higher leading into this update. The announcement confirms that the drilling program is active, a fact already known from the July 22, 2026, drilling-start announcement.
