Troilus Intercepts 2.44 g/t AuEq Over 23m Within Broader Zone of 1.79 g/t AuEq Over 36m; Extends High-Grade Zone to Surface in the Southwest Zone

MAY 22, 2025, Montreal, Quebec – Troilus Gold Corp. (“Troilus” or the “Company”, TSX: TLG; OTCQX: CHXMF; FSE: CM5R) is pleased to report additional positive drill results from the Southwest Zone (“Southwest”), at its Troilus Project located in northcentral Quebec, Canada. The results herein are part of the company’s 2025 drill campaign (outlined in the February 4, 2025 press release), 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 results reported today, following the initial results published on April 29, 2025, continue to demonstrate strong continuity of higher-grade mineralization at surface and reinforce the potential to optimize and de-risk the Southwest Zone block model, which currently covers years 1 to 5 of the mine plan.  Drill hole locations relative to the Southwest reserve pit are shown in Figure 1. All grades are uncut, and true thicknesses are approximately 75% to 90% of drilled length.

Southwest Highlights:

• Hole SW-25-681 intersected 1.79 g/t gold equivalent (“AuEq”) (1.40 g/t Au, 1.23 g/t Ag, 0.22 % Cu) over 36 m including 2.44 g/t AuEq (1.93 g/t Au, 1.85 g/t Ag, 0.29 % Cu) over 23 m starting at 51 m downhole and extending the continuity of high-grade mineralization to surface (See Figures 1 and 2).

• Hole SW-25-709 returned 1.52 g/t AuEq (1.15 g/t Au, 1.09 g/t Ag, 0.21 % Cu) over 21 m including 3.09 g/t AuEq (2.40 g/t Au, 1.92 g/t Ag, 0.39 % Cu) over 5 m starting at 44 m downhole and extending high-grade mineralization to surface (See Figure 1).

Justin Reid, CEO of Troilus Gold, commented, “We continue to be encouraged by the positive results reported from the Southwest Zone. Holes SW-25-681 and SW-25-709 have further highlighted the continuity of wide, high-grade mineralization, extending this system to surface. These results continue to de-risk and add confidence to the block model, and in doing so will allow optimization through re-interpretation of the high-grade zones in the Southwest Pit. With drilling now complete at the Southwest, we look forward to releasing the remaining results in the coming weeks, which will continue to provide additional confidence in the block model and help to de-risk the early years of production.”

Southwest Drilling

The drill program at the Southwest Zone focused on better defining high-grade zones in the early years of production. These results include intercepts of the high-grade core of the Southwest that will allow a re-interpretation of the resource, extending this enriched ore shoot to surface.

Drill hole SW-25-681 returned 1.79 g/t AuEq over 36 metres including 2.44 g/t AuEq over 23 metres, while SW-25-709 returned 1.52 g/t AuEq over 21 metres including 3.09 g/t AuEq over 5 metres. These intercepts demonstrate continuous results greater than 1 g/t AuEq, which speaks to the robust nature of the mineralized system (see Figure 2). Previously reported drill hole SW-25-688, the best intercept of the Southwest Zone to date, (see April 29, 2025 press release) intersected 2.44 g/t AuEq over 56 metres including 3.28 g/t AuEq over 34 metres from the same high-grade domain.

The high-grade core of the Southwest is hosted within transitional to tholeiitic brecciated pillow basalts wedged between a felsic porphyry dyke and the Troilus intrusion. Albite together with chlorite and carbonate, and to a lesser extend biotite and sericite alterations are associated with elevated gold grades, while potassic alteration is most notable in areas of higher-grade copper. This signature is the result of a protracted mineralized system that has allowed Troilus to become one of Canada’s largest undeveloped gold-copper projects, with 11.21 million gold equivalent ounces in the indicated category and an additional 1.80 million gold equivalent ounces in the inferred category (see October 16, 2023 press release).

Drilling in the Southwest Zone is now complete, with assays pending for several holes including those testing near-site conceptual targets. As results continue to be received and interpreted, the exploration team will shift focus, advancing near-site and regional field targets. The next phase of drilling is planned for the third quarter of 2025, with opportunities remaining to further expand on the highest-grade zones of the Southwest, as well as follow-up drilling of the many conceptual targets tested during phase one.

Quality Assurance and Control

During the drill program, one meter 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.

The technical and scientific information in this press release has been reviewed and approved by Nicolas Guest, P.Geo., Exploration Manager, who is a Qualified Person as defined by NI 43-101.  Mr. Guest is an employee of Troilus and is not independent of the Company under NI 43-101.

AuEq Disclosure

The formulas used to calculate equivalent values for resources are as follows, for 87 Pit AuEq = Au + 1.5628*Cu +0.0128 *Ag, for J Pit AuEq = Au + 1.5107*Cu +0.0119 *Ag, for SW Pit AuEq = Au + 1.6823*Cu +0.0124 *Ag, for X22 Pit AuEq = Au + 1.5628*Cu +0.0128 *Ag. AuEq was calculated using metal prices of $1,850/oz Au; $4.25/lb Cu and $23.00/oz Ag.
