Troilus Mining Corp. (TSX: TLG; OTCQX: CHXMF; FSE: CM5) has released initial results from its Z87 optimization drill program at the Troilus Project in north-central Quebec. The first batch includes 13 drill holes totaling 3,718 metres, targeting inferred mineralization and previously unsampled intervals within the Z87 reserve pit.
Key Drill Intercepts
Hole 87-26-505 intersected 0.95 g/t gold equivalent (AuEq) (0.82 g/t Au, 0.88 g/t Ag, 0.08% Cu) over 157.7 metres. This includes 1.37 g/t AuEq (1.28 g/t Au, 0.99 g/t Ag, 0.04% Cu) over 28 metres, 1.68 g/t AuEq (1.47 g/t Au, 0.91 g/t Ag, 0.12% Cu) over 30.9 metres, and 1.16 g/t AuEq (0.87 g/t Au, 1.54 g/t Ag, 0.17% Cu) over 19 metres starting at 238 metres downhole.
Hole 87-26-508 returned 1.10 g/t AuEq (0.90 g/t Au, 2.06 g/t Ag, 0.11% Cu) over 96 metres, including 2.59 g/t AuEq (2.28 g/t Au, 2.48 g/t Ag, 0.18% Cu) over 13.7 metres and 1.88 g/t AuEq (1.60 g/t Au, 3.10 g/t Ag, 0.15% Cu) over 16.5 metres starting at 284 metres downhole.
Hole 87-26-481 intersected 0.55 g/t AuEq (0.49 g/t Au, 0.34 g/t Ag, 0.03% Cu) over 83 metres, including 1.10 g/t AuEq (1.02 g/t Au, 0.43 g/t Ag, 0.05% Cu) over 20 metres starting at 298 metres downhole.
Program Objectives
The Z87 optimization program aims to support future mine planning by upgrading inferred material and filling gaps from historic drilling in the hangingwall of the main ore zone. All reported holes are within the Z87 reserve pit defined in the May 14, 2024 Feasibility Study. The results support evaluating opportunities for resource conversion, pit sequencing optimization, strip ratio improvements, and early-year mill feed flexibility.
Justin Reid, CEO of Troilus, stated: “The drill bit continues to deliver exciting results from within the reserve pit areas, and the Z87 program is steadily advancing exactly what it was designed to do. By targeting historically unsampled intervals in the hangingwall, upgrading inferred material and improving our understanding of mineralization within and around the existing pit shell, we are working to unlock opportunities that were not fully captured in previous drilling campaigns. Much of the hangingwall in Z87 was left unsampled during historical drill campaigns, creating gaps in the block model that we believe represent an important optimization opportunity. These initial results support our view that additional mineralized material may be better defined in this area, with the potential to enhance future sequencing, improve strip ratios and provide greater flexibility for early-year feed to the planned 50,000 tonne-per-day operation.”
Historical Context
Z87 was one of two zones previously mined by open pit at the Troilus Project. Many historic drill holes that defined the previously mined reserve were not fully sampled, with several hundred metres of core left unsampled. For resource estimation, these unsampled intervals are assigned a value equal to half the laboratory analysis detection limit, resulting in large gaps within the block model.
