New J Zone Extension On Western Limb While Extending Known Mineralization At Troilus Project
TORONTO - Troilus Gold Corp. reported positive drill results from the J Zone (11 455 meters) as part of the 2019 drilling program at its Troilus Gold Project, located within the Frotet-Evans Greenstone Belt in Quebec, Canada. Justin Reid, CEO of Troilus, said, “Not only are the latest results from the J Zone consistent with our earlier 2019 drill program resulting in significant improvement in grade and widths of mineralization across the deposit; they also expand our understanding of the mineralized system and have presented new possibilities for future exploration and development. With drilling complete, our team is busy compiling the data to incorporate into our mineral resource update which we plan to release later this year. This further increases our confidence in an expansion of the estimated Mineral Resource, demonstrating the clear success of this year’s drill program”
These new results have significantly extended the boundaries of known mineralization at depth from the north east to the south west in the J4 Zone, well beyond the formerly mined J4 pit. Highlights include holes TLG-ZJ419-112, TLG-ZJ419-166, located in the south west extremity of the former J4 pit and TLG-ZJ419-172, located in the center of the J4 pit. Both sections extended mineralization down dip approximately 300 meters and vertically approximately 250 meters beyond what was previously defined, which outlined extensions of mineralization 450 meters below the surface. Furthermore, the shallower intercepts from most holes presented in Table 1 are believed to be mineral extensions from the neighboring J5 mineral zone. This is further evidence the J4 and J5 zones may prove to be one and the same.
The J Zone hosts two mineral zones: J4 and J5. J4 is the smaller of the two formerly mined open pits along with the main Z87 zone. 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; 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. 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.
The new results from J Zone demonstrate a near surface continuity extending the mineralization up to 1.2 km to the south west beyond the limit of the former J5 Pit. Sections of holes TLG-ZJ419-172 and TLG-ZJ419-107 extend the continuity of the zone 500 meters on strike from the pit. Moreover hole TLG-ZJ419-164 defines a larger intercept 850 meters from the former open pit. The discovery of this mineralized extension is a result of the Company’s new understanding of the structural influence on mineralization across the deposit and the regional trend. Most of the sequence is composed of well laminated mafic volcanic unit, locally mineralized with semi-massive sulfide occurrences, with several similarities to the footwall sequence of 87 South zones.
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 identifying future growth opportunities. Overall results in this zone to date have been successful in achieving all 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.
