Troilus Drills 1.33 g/t AuEq Over 34 m Including 3.08 g/t AuEq Over 12 m in the Previously Unmineralized Z87 Hangingwall

Troilus reports strong Z87 drill results, but resource conversion remains a future step.

What the company is saying

Troilus Mining Corp. is highlighting the fifth batch of results from its Z87 optimization drill program at the Troilus Project in Quebec, Canada. The company emphasizes that eight new drill holes totaling 3,195 metres have intersected significant gold, copper, and silver mineralization, with headline intervals such as 3.08 g/t AuEq over 12 metres and 0.78 g/t AuEq over 131 metres in hole 87-26-524. Management, led by CEO Justin Reid, frames these results as reinforcing the potential to convert Inferred and waste material into higher-confidence resources, which could improve the mine plan, reduce the strip ratio, and enhance early mill feed. The announcement stresses that all 2026 drill results are excluded from the current resource and reserve estimates, but will be considered in future updates. The tone is confident but measured, with explicit acknowledgment that these results are not yet reflected in the September 2026 Technical Report. Technical disclosures are detailed, with calculation parameters, QA/QC protocols, and the involvement of Exploration Manager Nicolas Guest, P.Geo., as the Qualified Person.

What the data suggests

The disclosed data provides specific assay results from eight drill holes, including intervals such as 3.08 g/t AuEq over 12 metres, 1.33 g/t AuEq over 34 metres, and 0.78 g/t AuEq over 131 metres in hole 87-26-524, as well as 1.09 g/t AuEq over 59.5 metres in hole 87-26-536 and 0.79 g/t AuEq over 71 metres in hole 87-23-455-EXT26. True thicknesses are estimated at 75% to 90% of drilled length. The Z87 optimization program has now released results from 47 holes totaling 17,716 metres, out of a completed 22,800 metres. Metal price assumptions for AuEq are $2,415/oz gold, $4.60/lb copper, and $32.00/oz silver, with recovery rates ranging from 82.1% to 88.1% depending on pit area. The technical report completed in September 2026 supports a 26-year, 50,000-tonne-per-day open-pit operation, but the current resource and reserve models exclude all 2026 drill results. The data demonstrates mineralization in areas previously modeled as waste or Inferred, supporting the company's claim of potential resource conversion, but no updated resource or reserve figures are provided. All grades are uncut, and QA/QC protocols are described in detail.

Analysis

The announcement provides detailed, specific drill results from the Z87 optimization program, including grades, intervals, and technical parameters, all of which are standard and credible for an exploration-stage update. The language is factual and proportional to the evidence, with no exaggerated claims about immediate value creation. While the project is described as a large-scale, long-life mining operation, the benefits from these results are inherently long-term and contingent on future resource conversion and mine plan updates. The forward-looking statements are clearly identified as potential or targeted outcomes, not as realised achievements. There is no evidence of narrative inflation or overstatement; the technical data is robust and the tone is measured. The capital intensity flag is set because the project is described as a 26-year, 50,000-tpd operation, but this is contextual and not hyped.

Risk flags

• ●Resource conversion risk is material, as the current results are not yet incorporated into the official Mineral Resource or Reserve estimates. The actual impact on mine plan, economics, or project scale will depend on future modeling and regulatory review.
• ●Operational risk is present due to the reliance on converting Inferred and unsampled material into higher-confidence categories. If subsequent modeling or additional drilling fails to confirm continuity or grade, the anticipated improvements to strip ratio and mill feed may not materialize.
• ●Timeline risk is significant, as the technical and economic benefits from these results depend on future resource updates and potential permitting steps. There is no disclosed schedule for when these updates will be completed or when they might translate into revised project economics.
• ●Commodity price risk is embedded in the AuEq calculations, which use $2,415/oz gold, $4.60/lb copper, and $32.00/oz silver. If realized prices are materially lower, the economic attractiveness of converting marginal material could be reduced.
• ●Disclosure risk exists because, while technical data is detailed, there is no updated resource, reserve, or economic analysis accompanying these results. Investors must wait for future technical reports to assess the true impact.

Bottom line

Troilus Mining Corp.'s latest Z87 drill results show robust gold, copper, and silver mineralization in areas previously classified as waste or Inferred, with headline intercepts such as 3.08 g/t AuEq over 12 metres and 0.78 g/t AuEq over 131 metres. The company positions these results as having the potential to improve the mine plan, reduce strip ratio, and enhance early mill feed, but none of the 2026 drilling is yet included in the current resource or reserve estimates. All technical parameters, including metal prices and recoveries, are clearly disclosed, and QA/QC protocols are described in detail. The practical impact for investors is deferred, as resource conversion and economic benefits will only be realized after future modeling and technical report updates. The most important takeaway is that while the technical results are strong, the investment case hinges on successful resource conversion and subsequent economic validation in future disclosures.

Announcement summary

(TSX:TLG) (OTCQX:CHXMF) (FSE:CM5) Troilus Mining Corp. announced the fifth batch of results from its Z87 optimization drill program at the Troilus Project in north-central Quebec, Canada. The results include eight drill holes totaling 3,195 metres, as part of the 2026 exploration program. The Z87 optimization program targets Inferred and unsampled material within and around the current Z87 Reserve pit, aiming to improve the mine plan presented in the September 9, 2026 Technical Report. The current Mineral Resource and Mineral Reserve estimates have an effective date of December 31, 2025, and exclude all 2026 exploration results. Hole 87-26-524 intersected 3.08 g/t AuEq (3.04 g/t Au, 0.46 g/t Ag, 0.02% Cu) over 12 m within a broader interval of 1.33 g/t AuEq (1.29 g/t Au, 0.45 g/t Ag, 0.03% Cu) over 34 m starting at 207 m downhole. The same hole also returned 0.78 g/t AuEq (0.66 g/t Au, 1.06 g/t Ag, 0.08% Cu) over 131 m, including 1.41 g/t AuEq (1.22 g/t Au, 1.41 g/t Ag, 0.13% Cu) over 42.4 m starting at 435 m downhole. Hole 87-26-536 intersected 1.09 g/t AuEq (0.88 g/t Au, 3.36 g/t Ag, 0.13% Cu) over 59.5 m, including 2.32 g/t AuEq (1.92 g/t Au, 7.06 g/t Ag, 0.22% Cu) over 11 m starting at 485.5 m. Hole 87-23-455-EXT26 intersected 0.79 g/t AuEq (0.61 g/t Au, 1.54 g/t Ag, 0.12% Cu) over 71 m, including 1.23 g/t AuEq (1.09 g/t Au, 1.90 g/t Ag, 0.09% Cu) over 21 m starting at 514 m. All grades are uncut, and true thicknesses are approximately 75% to 90% of drilled length. To date, Troilus has released 47 drill holes totaling 17,716 metres of the completed Z87 pit optimization program, which amounted to approximately 22,800 metres of drilling. The Z87 optimization program is testing historically unsampled areas and Inferred material for potential resource conversion and mine plan improvements. The technical and scientific information in the press release was reviewed and approved by Nicolas Guest, P.Geo., Exploration Manager. AuEq was calculated using metal prices of $2,415/oz Au, $4.60/lb Cu, and $32.00/oz Ag, and recoveries of 84.5% for Au, 86.9% for Ag, and 88.1% for Cu in the J pit; 85.9% for Au, 87.6% for Ag, and 87.9% for Cu in the 87 pit; 82.1% for Au, 87.1% for Ag, and 87.1% for Cu in the SW pit; and 85.6% for Au, 87.0% for Ag, and 86.3% for Cu in the X22 pit. The Troilus Project is supported by a technical report completed in September 2026, outlining a 26-year, 50,000-tonne-per-day open-pit mining operation.
