Troilus Mining Corp. (TSX: TLG; OTCQX: CHXMF; FSE: CM5) has announced additional drill results from its Z87 optimization program at the Troilus Project in north-central Quebec, Canada. The results include 7 drill holes totaling 1,845 metres, targeting inferred and historically unsampled material within and around the Z87 reserve pit shell. 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.
Key Intercept: 164 Metres at 0.95 g/t AuEq
Hole 87-26-507 intersected 0.95 g/t gold equivalent (AuEq) (0.83 g/t Au, 1.30 g/t Ag, 0.06% Cu) over 164 metres, including 1.38 g/t AuEq (1.26 g/t Au, 1.09 g/t Ag, 0.07% Cu) over 46 metres starting at 373 metres downhole, and 1.22 g/t AuEq (1.06 g/t Au, 1.74 g/t Ag, 0.09% Cu) over 61 metres, including 3.10 g/t AuEq (2.70 g/t Au, 1.82 g/t Ag, 0.24% Cu) over 9 metres starting at 476 metres downhole. This intercept expands the main zone beyond limited historic sampling.
Additional Hangingwall Intercepts
Hole 87-26-487 intersected 0.82 g/t AuEq (0.66 g/t Au, 0.93 g/t Ag, 0.09% Cu) over 39.6 metres, including 1.36 g/t AuEq (1.10 g/t Au, 1.36 g/t Ag, 0.15% Cu) over 17 metres from the Z87 hangingwall starting at 164 metres downhole. Hole 87-26-501 intersected 0.64 g/t AuEq (0.51 g/t Au, 0.90 g/t Ag, 0.07% Cu) over 75 metres, including 1.31 g/t AuEq (0.94 g/t Au, 2.91 g/t Ag, 0.21% Cu) over 14 metres from the Z87 hangingwall starting at 190 metres downhole.
Optimization Program Targets
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 are located within the Z87 reserve pit, as defined in the Feasibility Study (see May 14, 2024 press release). The program supports 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.
Justin Reid, CEO of Troilus, commented: “This deposit keeps getting better. These latest results from Z87 continue to demonstrate the value of our optimization program and the opportunity that remains within the existing reserve pit. With two drills active at site this year, we are systematically testing areas where historical drilling left meaningful gaps in the model, while also targeting inferred material for potential upgrading. If we can define additional ore tonnes within the current mine design, we believe there is a real opportunity to improve strip ratios, enhance sequencing flexibility and provide greater optionality as we plan to feed the future 50,000 tonne-per-day operation.”
Historic Sampling Gaps
Z87 was one of two zones previously mined by open pit. Many of the historic drillholes that defined the previously mined reserve were not fully sampled, with several hundred metres of core left unsampled in many holes. For resource estimation purposes, these unsampled intervals are assigned a value equal to half the laboratory analysis detection limit, resulting in large gaps within the block model. The current drilling aims to fill these gaps and potentially upgrade the resource classification.
