Troilus Drills 78.38 g/t AuEq Over 2 M, Including 153.73 g/t AuEq Over 1 m in the Southwest Zone
Press Release
JUNE 17, 2025, Montreal, Quebec – Troilus Gold Corp. (“Troilus” or the “Company”, TSX: TLG; OTCQX: CHXMF; FSE: CM5R) is pleased to announce the final assay results from the Southwest Zone (“Southwest”) as part of its ongoing 2025 Exploration Program (see February 4, 2025 press release) at its Troilus Project located in northcentral Quebec, Canada. The now concluded Southwest drill program focused on identifying and delineating higher-grade mineralization and enhancing confidence in the block model within the Southwest Zone as outlined in the May 2024 Feasibility Study (see May 14, 2024 press release).
The Southwest drill program produced impactful results that have confirmed and extended the continuity of higher-grade material within the Phase 1 reserve pit, which encompasses years 1 to 5 of the mine plan. All intercepts reported herein lie within the current mine plan and have the potential to support optimization of the early production schedule. All grades are uncut, and true thicknesses are approximately 75% to 90% of drilled length. Please refer to the press releases from April 29, 2025 and May 22, 2025 for additional results from the 2025 Exploration Program.
Southwest Intercept Highlights (see Figure 1):
- Hole SW-25-678 intersected 78.38 g/t gold equivalent (“AuEq”) (78.21 g/t Au, 5.95 g/t Ag, 0.06 % Cu) over 2 m, including 153.73 g/t AuEq (153.50 g/t Au, 11.00 g/t Ag, 0.06 % Cu) over 1 m starting at 120m downhole. This narrow yet high grade intercept represents the single best assay from the Southwest zone to date.
- Hole SW-25-719 intersected 0.94 g/t AuEq (0.88 g/t Au, 0.39 g/t Ag, 0.03 % Cu) over 73 m, including 2.62 g/t AuEq (2.50 g/t Au, 0.70 g/t Ag, 0.07 % Cu) over 1 m and 15.15 g/t AuEq (15.05 g/t Au, 1.05 g/t Ag, 0.05 % Cu) over 2 m starting at 137 m downhole.
- Hole SW-25-703 intersected 0.92 g/t AuEq (0.73 g/t Au, 1.55 g/t Ag, 0.10 % Cu) over 69.3 m, including 20.93 g/t AuEq (20.90 g/t Au, 0.80 g/t Ag, 0.01 % Cu) over 1 m starting at 84 m downhole.
Justin Reid, CEO of Troilus, commented, “The 2025 drill campaign delivered exactly what we set out to achieve in providing greater confidence in the block model and the discovery of additional high grade mineralization. With Phase 1 of mining focused on the Southwest Zone in years 1-5, these newly identified high-grade ounces could be particularly impactful. Our geology team continues to interpret results and is confident in the opportunity for further growth. As we advance toward a construction decision, these results help de-risk the project and reinforces its long-term value.”

Southwest Drilling
Drill hole SW-25-678 returned 78.41 g/t AuEq over 2 metres including 153.80 g/t over 1 metre, which is the single highest assay returned from the Southwest since the start of drilling in 2019. This intercept is hosted within a highly sheared felsic porphyry unit with a visible gold-bearing, foliation-parallel quartz-pyrite-tourmaline vein. These veins are interpreted to be the result of an overprinting orogenic gold event, that also remobilized and redistributed mineralization from earlier volcano-magmatic events. It is this overprinting relationship and long history of mineralizing events that have contributed to the scale of the Troilus resource, which stands at 11.21 Moz AuEq in Indicated category, and 1.80 Moz AuEq in the Inferred category (see October 16, 2023 press release).
Drillholes SW-24-703 and 719 returned 0.92 g/t AuEq over 69.3 m and 0.94 g/t AuEq over 73 m, respectively. Both intercepts are hosted within a distinct brecciated and magnetic volcanic unit that is the dominant host to ore in the Southwest. These results confirm strong continuity of the primary ore zones in the Southwest.
Some of the exploration drill holes from the Southwest drill program served a dual purpose as geotechnical holes, providing valuable data that will be incorporated into the updated pit designs, further de-risking the earliest years of production.
Next Steps
The exploration team is now incorporating these final drill results into the Southwest resource model and is shifting its focus to near-site and regional field targets. A soil sampling program of approximately 3,700 samples is currently underway, and results are pending from a 2,100 line-kilometre versatile time-domain electromagnetic (“VTEM”) survey completed earlier this year.
The next phase of drilling is planned for the third quarter of 2025, targeting futher high-grade extensions in the Southwest and follow-up drilling of conceptual targets that lie outside current mine plans.
