Troilus Gold Corp. (TSX: TLG) (OTCQB: CHXMF) reports drill results from the J Zone at its Troilus Gold Project, located within the Frotêt-Evans Greenstone Belt in Quebec, Canada.
Intercept highlights from this group of drill results include:
Justin Reid, CEO of Troilus, commented, “We are very excited by these results that continue to prove the quality and significant exploration upside of our deposit. Intersections with grades and widths that are in line with our November 2018 mineral resource estimate are consistently extending mineralization well beyond the previously known limits, which we believe could have a meaningful impact on the mineral resource update planned later this year. We are concluding our initial 2019 drill program and look forward to issuing additional results from our primary target areas in short order.”
Mineral Boundaries Significantly Extended
The new results have significantly extended the boundaries of known mineralization to the north east and south west in the J4 Zone, well beyond the formerly mined J4 pit. Highlights include holes TLG-ZJ419-158 and TLG-ZJ419-159, located in the north east extremity of the former J4 pit which extended mineralization down dip approximately 225 metres and vertically approximately 200 metres beyond what was previously defined (See Figure 3), and hole TLG-ZJ419-110 drilled in the south west edge of the J4 pit (See Figure 1), which outlined extensions of mineralization 400 metres below the pit. Furthermore, the shallower intercepts from holes ZJ419-158 and TLG-ZJ419-159 are believed to be mineral extensions from the neighbouring J5 mineral zone, suggesting that the J4 and J5 zones may prove to be one and the same with additional drill density (See Figure 3). All mineral intersections along hole TLG-ZJ419-159 remain open and undrilled further at depth.
High Grade Gold Trends
As initially reported in the June 18, 2019, press release, the Company is continuing to outline high grade gold trends within a broader mineralized envelope which are becoming apparent throughout the entire ore body. Hole TLG-ZJ419-159, for example, intersected 37.84 g/t gold equivalent (AuEq) over 2 metres within 4.41 g/t AuEq over 20 metres and 4.59 g/t AuEq over 2 metres within 0.93 g/t AuEq over 14 metres in a previously barren zone, representing a much thicker and richer area than the connecting intercepts above them. The mineralization in Section 14950, Figure 3, illustrates the reoccurring pinch and swell nature of mineralization associated with quartz veins, which is consistent with the other main mineral zones on the property (see example from Z87 pit wall in Figure 4).
J Zone Geology Overview
The J Zone hosts two mineral zones, J4 and J5; J4 being the smaller of the two formerly mined open pits along with the main Z87 zone (See Figure 1). The ore bodies in the J4 zone are hosted in the northern continuity of the Troilus Diorite and, similarly to what is observed in the main zones Z87 and Z87 South, are elongated parallel to a penetrative NE-trending foliation, moderately to steeply dipping to the north west. From top to bottom, the sequence comprises (i) a volcaniclastic unit, occurring along the hanging wall of the mineralization, and composed of well laminated intermediate to felsic rocks, locally mineralized, with semi-massive sulfide occurrences, resembling the footwall sequence of the Z87 and 87 South zones; and (ii) a thick metadioritic unit, comprising fine to coarse grained diorites, locally brecciated, commonly crosscut by decimetric to metric felsic dikes, which mostly occur concentrated in the upper parts of the sequence, in the immediate hanging wall of the mineralized intervals. Towards the bottom of the sequence, in the footwall, typical diorite breccias are present, displaying an intense silicification and being locally importantly mineralized (for example the southern portions of J4; holes TLG-J419-109 and TLG-J419-92). The main mineralized intervals in the J4 zone are characterized by sulfide stringers and fine sulfide disseminations along the foliation occurring within a very fine grained biotite-rich and silicified diorite. Pyrite is the main sulfide, and it is intrinsically associated with gold mineralization. High-grade mineralization in the J4 zone is associated with unusual sulfide-rich quartz veins (Ex: hole TLG-J419-94), and with a coarse grained to porphyritic diorite, continually intercepted in the northern region of J4 (Ex: holes TLG-J419-153 and TLG-J419-159).
The 2019 drill program in the J Zone was primarily designed to expand near-surface mineralization to support an open-pit mine development scenario, while improving the geological understanding of the main mineral trend and to identify future growth opportunities. Results in this zone to date have been successful in achieving these objectives, and the Company has already begun to outline future drill targets to further improve resolution and continue defining the mineral boundaries along the Troilus trend.
Troilus has completed the drill program that was set out for 2019, and is awaiting additional results from the Z87 South area, as well as the J4 and J4 North zones, however the regional surface exploration program along the Troilus trend is ongoing.

During the J4 Zone drill program, two metres assay samples are taken from NQ core and sawed in half. One-half is sent for assaying at ALS Laboratory, a certified commercial laboratory, and the other half is retained for results, cross checks, and future reference. A strict QA/QC program is applied to all samples; which include insertion of one certified mineralized standard and one blank sample in each batch of 25 samples. The gold analyses were by metallic sieve. A fine crushing 70% <2mm is performed. The sample is divided so that 1.2 to 1.5 kg is used for analysis. The sample of 1.2 to 1.5 Kg is then 95% pulverized <106 mesh. 50 g is recovered for ME-ICP61 analysis of 33 elements four acid ICP-AES. The remainder of the sample is sent to the screen to divide the fraction larger and smaller than 106 mesh. The portion smaller than 106 mesh is analyzed in 50 g by Fire Assay. The portion larger than 106 mesh is fully analyzed. The values are then combined by weighted calculation. For both type results are transmitted to Troilus Gold by a certificate certified by the laboratory.
