Troilus Extends Strike Length of Southwest Zone ~25% to +1.85 kms, 350 Metres Beyond Known Mineralization; Drills 1.20 g/t AuEq Over 19 Metres Within 100 Metres From Surface

 

 

 

 

 

Troilus Gold Corp. (TSX: TLG) (OTCQX: CHXMF) reports additional assay results from the Southwest Zone as part of its ongoing expansion and definition drilling program at its 100%-owned Troilus deposit, located in northcentral Quebec, Canada. The latest results have expanded the ore body to the southwest, well beyond the pit shell proposed in the Preliminary Economic Assessment published in August 2020. The Southwest Zone is located ~2.5 kilometres southwest of the former mine and main mineral zones (Z87, Z87 South and J Zone) and has become one of the most important mineral growth targets on the Troilus property since it was initially discovered and drilled in late 2019. Drill hole locations are provided in Figures 1 and 2, and results in Table 1.

 

Summary of Results:

 

  • Results from six new broad step-out drill holes covering a previously untested area of 200m by 650m confirm significant strike extension up to 300 metres beyond the PEA pit shell.
  • All holes drilled entirely outside of the PEA pit shell. Intercept highlights from new Southwest extension, include:
    • 1.20 g/t AuEq over 19m and 1.51 g/t AuEq over 11m, within a broader intersection of 0.97 g/t AuEq over 26m in drill hole ZSW21-530. This stand-out hole is located 350 metres away from known mineralization.
    • 4.90 g/t AuEq over 4m, incl. 15.56 g/t AuEq over 1m; 1.77g/t AuEq over 4m, incl. 3.06 g/t AuEq over 2m; 12.77 g/t AuEq over 1m in drill hole ZSW21-510
    • 1.03 g/t AuEq over 16m, incl. 1.52 g/t AuEq over 4m and 1.23 g/t AuEq over 6m in drill hole ZSW21-216
    • 1.28 g/t AuEq over 7m and 3.31 g/t over 1m, within broader intercept of 0.93 g/t AuEq over 11m; and 11.22 g/t AuEq over 1m in drill hole ZSW21-529
    • 2.63 g/t AuEq over 2m, within broader intercept of 0.95 g/t AuEq over 7m in drill hole ZSW21-528
  • Mineral continuity established between 50 to 100 metre sections in new southwest extension supports new structurally focused geological model and suggests a much broader system extending well beyond existing mineral envelope.
  • Drilling is ongoing at a rate of ~7,000 metres per month with 3 drill rigs focused on the Southwest Zone expansion and improving drill density in the recently identified parallel mineral structure in the J Zone (see press release dated September 21, 2021).
  • As a result of the ongoing drilling success at Troilus, demonstrating particularly important technical developments and growth in the Southwest and J Zones, the mineral resource estimate is now targeted for completion in H1 2022, in conjunction with the Pre-Feasibility Study. The impact of recent results on the overall future mine could be significant, and the updated timeline will allow for the inclusion of the upcoming few months of drill data as the size and extent of these ore bodies are defined. A minimum of 20,000 additional metres of drilling is planned to be completed on the Southwest Zone to test the extent of the gold zone with the goal of bringing the level of confidence to pre-feasibility quality.

 

Justin Reid, President, CEO and Director of Troilus Gold, stated, “These new results are very exciting as they confirm our exploration team’s latest geological modelling suggesting mineral continuity well beyond the southern extent of this zone, replacing a previous “narrow hinge” model in which it was thought to taper off. The ongoing drilling from late 2020 and throughout 2021 has resulted in major technical advancements that continue to unfold. We believe that the impact of the ongoing definition of shallow and above average grade mineralization in the Southwest Zone is too important not to be considered in the upcoming studies and overall mine plan; the original Q4 2021 timing of the resource estimate would have prevented us from considering these important results. As we continue to define the extent of the Troilus deposit, our outlook on the scale and robustness of the project has never been more positive.”

 

Southwest Zone: 2019 Discovery to Present

 

  • Initial drilling in late 2019
  • 8,500 metres of drilling contributes 583,000 oz to the Inferred mineral resource of July 2020
  • Strike length has more than doubled since late 2020, from 850 metres to 1.85 kilometres
  • Over 40,000 metres drilled in the Southwest Zone since the 2020 mineral resource cut-off
  • Remains open in all directions

 

The Southwest Zone is located 2.5 kilometres southwest of Z87, the former mine’s main production pit, and lies along the margin of the Troilus Diorite and surrounding volcanics. Initial prospecting and mapping started in 2018 to follow-up on some sparse and shallow drilling completed by Inmet Mining Corporation from 1986 to 2000, which returned intercepts as high as 1.23 g/t gold over 36 metres and 1.06 g/t gold over 18 metres. Since drilling began in November 2019, Troilus’ exploration team has successfully delineated a homogeneous body of mineralization that is geologically similar to the main zone Z87, extending over a strike length of 1.85 kilometres and up to 420 metres in width.

 

While the primary lithology and poly-phase alteration and depositional event that likely emplaced the mineralization at Southwest Zone appears to be the same as what has been observed in the Z87 open pit, which produced over one million ounces of gold and copper bearing ore, the intensity of the alteration is stronger. The zone appears darker, intense amphibolite level metamorphism, and carries significantly more magnetite, as well as a trend of increasing amounts of base metals.

 

The grades in the Southwest Zone have generally been observed to be higher than the other mineral zones at Troilus with a greater frequency of visible gold, and includes some the best intercepts ever recorded at Troilus, including 3.58 g/t AuEq over 15m, incl. 6.76 g/t AuEq over 7m in hole ZSW21-512 (see August 17, 2021 press release) and 1.56 g/t AuEq over 73m, including 2.05 g/t AuEq over 48m in hole ZSW20-189 (see press release dated April 21, 2020). The technical team remain focused on developing the new structural model and hope to be successful in modelling high grade trends within the broader mineralized package.

 

The July 2020 mineral resource estimate included 8,500 metres of drilling from the Southwest Zone, which
contributed 583,000 oz of Inferred resources (22.6 Mt @ 0.80 g/t AuEq) to the total mineral resources of 4.96 Moz AuEq in the Indicated category (177.3Mt @ 0.87 g/t) and 3.15 Moz AuEq in the Inferred category (116.7Mt @ 0.84 g/t) (see press release dated July 28, 2020). Since the 2020 mineral resource cut-off, over 40,000 metres have been drilled in the Southwest Zone, which has to date more than doubled the strike length of mineralization from 850 metres to 1.85km. As evidenced by today’s results, the Southwest zone still remains open in all directions and the next few months of drilling will aim to continue defining the extent of the mineral envelope.

Quality Assurance and Control

 

During the Southwest Zone drill program in 2021, one metre assay samples were taken from NQ core and sawed in half. One-half was sent for assaying at ALS Laboratory, a certified commercial laboratory, and the other half was retained for results, cross checks, and future reference. A strict QA/QC program was applied to all samples; which included insertion of one certified mineralized standard and one blank sample in each batch of 25 samples. Every sample was processed with standard crushing to 85% passing 75 microns on 500 g splits. Samples were assayed by one-AT (30 g) fire assay with an AA finish and if results were higher than 3.5 g/t Au, assays were redone with a gravimetric finish. For QA/QC samples, a 50 g fire assay was done. In addition to gold, ALS laboratory carried out multi-element analysis for ME-ICP61 analysis of 33 elements four acid ICP-AES.
