Troilus Gold Corp. (TSX: TLG) (OTCQX: CHXMF) is pleased to announce drill results from its high-grade gold-copper-silver Testard target, located approximately 10 kilometres south of the main mineral corridor and former mine site. The Troilus gold-copper project is located within the Company’s 142,000 hectares (1,420 km²) land package in northcentral Quebec, Canada, where it holds the largest contiguous mineral claims within the Frôtet-Evans Greenstone Belt.
Troilus acquired the Testard claim area in early 2020 and proceeded with surface mapping and prospecting over the course of that Summer, which returned the highest-grade gold occurrences ever reported in outcrop within the Frotêt-Evans Greenstone Belt. This drilling program aimed to test the potential controls on mineralization in the area, while also testing extensions of the high-grade mineralization below surface at the main showing.
Result Highlights (See Table 1 for complete results)
New discovery drilled 400 metres from main Testard surface outcrop:
Holes TES-21-001 and TES-21-002 intersected gold-rich quartz veins ~400 metres northwest of the main Testard outcrop (See Figure 1).
Excellent outcrop and channel sample results confirmed below surface
Drill hole TES-21-005 targeted and intersected mineralized gold bearing structures at depth below previously sampled outcrop. Intercept highlights include:
Highlights from previously reported surface results (see press releases dated Oct. 19 and Dec. 9, 2020) located in proximity to hole TES-21-005 include:
Justin Reid, President and CEO, commented, “The results from our first test drilling program at Testard are very exciting. The structural model developed by our geological team used to identify these initial drill targets, some of which are nearly half a kilometre away from the main showing, is truly impressive. Testard has returned the highest insitu gold and silver grades identified to date within the entire Frôtet-Evans Greenstone Belt; these initial drill results are hugely motivating to our team as we continue to assess results and further develop our models in preparation for an expanded drill program. Though early, the proximity of this target to our future operation, powerline, access roads and infrastructure warrants further work, especially considering these exciting grades.”
Blake Hylands, Senior Vice-President of Exploration, commented, “The team has done outstanding work at the Testard area. Not only have the high-grade showings discovered in the Summer of 2020 been proven to extend below surface, but the discovery of shear hosted mineralization almost half a kilometre from there is now painting the picture of a much larger, multikilometer system that we intend to prove in the coming months. We are optimistic that these results will continue to be duplicated around the Testard area, and we point to it as real evidence of the district scale potential at Troilus we have argued for years.”
Figure 1: Plan Map of Testard with Drilling Highlights:
The mineralized structures encountered consist of shear-hosted quartz-tourmaline-carbonate veins contained within a sericite-silica-carbonate altered tonalite (See Figure 2). The best gold and silver values were obtained from veins that contain disseminated, to up to 20% pyrite, with locally trace chalcopyrite and molybdenite. Different vein textures have been observed in core including laminated, extensional and breccia-type veins. Further drilling is needed to better constrain the Azimuth and dip of the different mineralized trends.

Testard Target: 2020-Present and Next Steps Towards Finding Main Source of Mineralization
The Testard claims were staked in 2020 (see April 28, 2020 and July 21, 2020 press releases) following the discovery of the Southwest Zone, 2.5 kilometres away from the formerly mined pits (Zones Z87 and J Zone). Over the course of two years, Troilus increased its land position nearly 9-fold from 16,000 hectares to 142,000 ha (1,420 km²), driven by increasing evidence that the known Troilus deposits were part of a larger, regional scale gold system.
The initial work program completed at Testard in the Summer of 2020, including outcrop stripping, bedrock mapping and boulder tracing, returned the highest-grade gold occurrences on Troilus’ property to date, and the highest ever reported in outcrop within the Frotêt-Evans Greenstone Belt. Furthermore, the results demonstrated that the geological characteristics of the Testard Zone and host rock share many similarities to the main mineral resource zones, which hosts estimated mineral resources of 4.96 Moz AuEq Indicated (177 Mt grading 0.87 g/t AuEq) and 3.15 Moz AuEq Inferred (116.7 Mt grading 0.84 g/t AuEq) (see July 28, 2020 press release).
Testard has been a priority regional target on which extensive work has been completed over the last 18 months, including geological sampling and mapping of lithology and structure, detailed airborne magnetics and an induced polarization survey. The results of this work enabled Troilus’ geology team to develop a structural interpretation of mineralization at Testard; that being a NE-SW structure parallel to the main Troilus deposit, with east-west cross cutting shearing and quartz vein sets identified as potential physical traps for high grade mineralization (see Figure 3). Detailed airborne magnetic data (shown in Figure 3) clearly outlines a main contact zone between the more magnetic ultramafic and the less magnetic tonalite units. The contact zone was observed in the field to be intensely sheared, and therefore a potential prospective pathway for mineralization. The use of magnetics and induced polarization (IP) data together allowed for additional east-west structural interpretations of the Testard area, which appear to cross-cut the main shear zone.

Results from Troilus’ maiden drill program announced today confirm gold bearing structures exist in proximity to the main NE-SW shear/contact zone, specifically with holes TES-21-001 and TES-21-002, which intersected gold-rich quartz veins ~400 metres northwest of the main showing at the intersection of interpreted east-west structural features and the NE-SW trending shear zone.
Assessment of the results obtained from the drilling program is underway, one of the main goals being to develop models for the orientation of gold-bearing veins. An additional drilling program will be developed to build out from the successes of this initial program.

Quality Assurance and Control
During the Testard drill program in 2021, one metre assay samples were taken from BTW 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.
