The program targets inferred and historically unsampled intervals currently modelled partly as waste, aiming to support resource conversion, pit and mine-plan optimization, and improved strip ratios. To date, 39 holes totalling 14,521 m of an approximately 24,000 m Z87 program have been released.
Troilus Mining Corp (CHXMF) will be added to the VanEck Junior Gold Miners ETF (GDXJ) at market close on September 18, 2026, as part of the ETF’s quarterly rebalancing.
The GDXJ provides exposure to a diversified portfolio of small- and mid-cap gold and silver miners, and inclusion is expected by the company to broaden Troilus’ reach to institutional, passive and retail investors, while supporting market visibility and trading liquidity. Management highlights recent project milestones including completion of Basic Engineering, progress in Detailed Engineering, permitting, procurement and project financing, and an updated Technical Report that it says strengthens the technical and economic foundation of the Troilus Project.
Troilus Mining (CHXMF) reports that its Troilus gold-copper project has been selected for inclusion in the Canada Investment Summit Prospectus for the Sept. 14–15, 2026 forum in Toronto.
The summit, hosted by Prime Minister Mark Carney with CPP Investments and PSP Investments, will gather investors managing more than $100 trillion in assets, giving Troilus direct visibility to a large global institutional audience. The company highlights its updated 2026 NI 43-101 Technical Report, which at base-case prices shows an after-tax NPV(5%) of US$3.2 billion, a 22% IRR, a 3.6-year payback and a mine life of about 26 years. Troilus is advancing detailed engineering, procurement, permitting and project financing in parallel, including a senior secured project financing mandate of up to US$1.2 billion.
Troilus Mining (CHXMF) released an updated NI 43-101 Technical Report for its gold-copper Troilus Project in Quebec, based on completed Basic Engineering, outlining a 26-year open-pit mine with after-tax NPV(5%) of US$3.2 billion, 22% IRR and a 3.6-year payback at a base gold price of US$3,600/oz.
The plan is underpinned by 478 million tonnes of Proven and Probable Reserves grading 0.44 g/t gold, 0.05% copper and 0.92 g/t silver, supporting life-of-mine payable output of 5.63 million ounces of gold, 472 million pounds of copper and 10.88 million ounces of silver. Initial capital is estimated at US$1.428 billion, with life-of-mine operating costs of US$19.21/t milled and AISC of US$1,340 per payable gold ounce. The estimate reflects roughly 95,000 engineering hours, ~90% market‑validated pricing and meets AACE Class 3 (+15%/‑10%) accuracy, which the company said strengthens the basis for financing and execution.
Troilus Mining (OTCQX: CHXMF) announced that Finland’s export credit agency Finnvera has issued a non-binding Letter of Interest connected to the recently awarded Metso equipment procurement for the Troilus gold-copper project in Québec. The LOI relates to an estimated US$155 million export transaction for Metso equipment and services.
Under the contemplated structure, Finnvera may support financing of up to 85% of eligible imported goods and services, representing up to approximately US$132 million, to be provided via an eligible commercial bank with Finnvera support. According to the company, this potential facility would complement its ongoing senior secured project financing mandate of up to US$1.2 billion with Société Générale, KfW IPEX-Bank and Export Development Canada, and further aligns procurement and financing as the project advances toward construction. The LOI remains non-binding and subject to due diligence and final approvals.
Troilus Mining (TSX: TLG; OTCQX: CHXMF) has selected Metso for the first phase of major process equipment procurement for its gold-copper Troilus Project in north-central Québec, issuing a Letter of Award and Limited Notice to Proceed covering crushers, feeders, screens, HPGRs and ball mills.
Metso is already integrated into Troilus’ Detailed Engineering through technical workshops on equipment interfaces, plant layout, 3D modelling and construction planning. The parties are also negotiating a Life Cycle Services framework including commissioning and ramp-up support, capital spares, extended warranties, an on-site HPGR service center and workforce training. Troilus is targeting completion of definitive equipment and service arrangements in September 2026, alongside broader Detailed Engineering, early contractor involvement, permitting and project financing to prepare for a transition into construction.
Troilus Mining (OTCQX: CHXMF) reported new drill results from five extended drill holes totaling 2,915 metres at the Z87 underground target of its Troilus gold-copper project in Quebec. The program tested down-plunge continuity up to 400 metres beyond the current Z87 resource pit shell.
Key intercepts include 8.84 g/t AuEq over 4.8 m (including 23.58 g/t AuEq over 1 m) in hole TLG-ZJ20-222-EXT26 about 300 metres beyond the existing resource, and 5.07 g/t AuEq over 5 m in hole TLG-ZJ19-094-EXT26. Hole TLG-ZJ19-165-EXT26 extended known mineralization 400 metres beyond the current resource with 2.84 g/t AuEq over 3.7 m within 1.71 g/t AuEq over 8.2 m.
All five re-entered J Zone holes intersected mineralization, supporting geological continuity and indicating untested areas around the Z87 high-grade core and Parker granite contact. According to Troilus, results will feed future geological model updates alongside a 2024 Feasibility Study outlining a 22-year, 50,000 tpd open-pit operation.
Troilus Mining (OTCQX: CHXMF, TSX: TLG) announced that its copper-gold Troilus Project has been selected by Québec’s Minister of Natural Resources and Forests as one of the first projects to receive specialized permitting support under the Government of Québec’s new Filon initiative for strategic mining projects.
Filon assigns Troilus a dedicated mining expert to coordinate with ministries and agencies, identify bottlenecks and facilitate permit authorizations while maintaining Québec’s environmental review standards. The project filed its ESIA in June 2025, secured a 70 MW Hydro-Québec power allocation in June 2026, and is advancing detailed engineering and financing, supported by a May 2024 Feasibility Study outlining a 22-year, 50 ktpd open-pit operation.
Troilus Mining (OTCQX: CHXMF) reported the third batch of 2026 Z87 optimization drill results from its Troilus Project in Quebec, covering 10 holes totaling 4,230 m. The program targets inferred and historically unsampled hangingwall material within the Z87 reserve pit defined in the 2024 Feasibility Study.
Key intercepts include hole 87-26-484 with 1.10 g/t AuEq over 103 m, including 2.10 g/t AuEq over 34 m from inferred material; hole 87-26-492 with 1.98 g/t AuEq over 14 m, including 9.87 g/t AuEq over 1.5 m from the hangingwall; and hole 87-26-512 with 0.92 g/t AuEq over 93 m, including 2.30 g/t AuEq over 21 m and additional mineralization in previously unsampled hangingwall zones.
According to Troilus, results support opportunities for resource conversion, pit sequencing optimization, strip ratio improvements and early-year mill feed. To date, 30 holes totaling 9,793 m have been released from the ~24,000 m Z87 optimization program.
Troilus Mining (OTCQX:CHXMF) reported new drilling results from the Z87 optimization program at its Quebec Troilus Project.
Key intercepts within the existing Z87 reserve pit include 164 m at 0.95 g/t AuEq in hole 87-26-507 and significant hangingwall mineralization in holes 87-26-487 and 87-26-501.
The work targets historically unsampled intervals and inferred material to support potential resource conversion, strip ratio improvements and enhanced early mill feed flexibility for the planned 50,000 tpd operation.
