*8.84 G/T AUEQ (7.02 G/T AU, 21.63 G/T AG, 1.03% CU) OVER 4.8 M

MONTREAL, Aug. 20, 2026 (GLOBE NEWSWIRE) -- Troilus Mining Corp. (“Troilus” or the “Company”) ( TSX: TLG; OTCQX: CHXMF; FSE: CM5 ) is pleased to announce results from five drill holes totaling 2,915 metres completed as part of the ongoing Z87 extension drilling program at its gold-copper Troilus Project located in north-central Quebec, Canada.

All five holes were extensions of existing drillholes originating from the J Zone and were designed to test the down-plunge continuity of high-grade Z87 mineralization beyond the existing mineral resource (see the 2023 Mineral Resource Estimate in the October 16, 2023, press release ).
