Troilus drills 164 m grading 0.95 g/t AuEq in Z87 Reserve Pit

*0.95 G/T AUEQ (0.83 G/T AU, 1.30 G/T AG, 0.06 % CU) OVER 164 M MONTREAL, July 07, 2026 (GLOBE NEWSWIRE) -- Troilus Mining Corp. (“Troilus” or the “Company”) ( TSX: TLG; OTCQX: CHXMF; FSE: CM5 ), is pleased to announce additional results from the Z87 optimization drill program, as part of its ongoing 2026 exploration activities at the Troilus Project located in north-central Quebec, Canada. The results reported include 7 drill holes totalling 1,845 metres, following the exploration program outlined in the Company’s March 31, 2026 press release . To date, Troilus has released results from 20 drill holes totalling 5,563 metres of the approximately 24,000 metres allocated to the Z87 pit optimization program, which is targeting inferred and historically unsampled material within and around the Z87 reserve pit shell.

The ongoing Z87 optimization program is designed to upgrade inferred material and target unsampled intervals from historic drilling within the hangingwall of the main ore zone. All results reported today are located within the Z87 reserve pit, as defined in the Feasibility Study ( see May 14, 2024 press release ), and continue to support the Company’s objective of evaluating opportunities to improve future mine planning, including potential resource conversion, pit sequencing optimization, strip ratio improvements and early-year mill feed flexibility.
