TLG Troilus Gold Corp

Troilus Gold Corp. (TSX: TLG; OTCQX: CHXMF; FRA: CM5R) (“Troilus” or the “Company”), is pleased to provide a review of its key accomplishments in 2023 as well as an outlook for 2024 in this open letter to shareholders from Chief Executive Officer and Director, Justin Reid.

To our valued shareholders and stakeholders,

As we close another year, it is with pride that I look back on the significant accomplishments Troilus has made in 2023. Despite a turbulent year in the junior mining sector, compounded by the unforeseen challenges of the devastating forest fires in Quebec, our steadfast focus and commitment significantly enhanced the Troilus Project, establishing it as one of the largest undeveloped gold-copper deposits in North America. As a founder and significant shareholder of the Company, I share the sentiment of aspiring for greater returns and am excited about the potential that 2024 holds. This year will see major de-risking milestones that promise to solidify Troilus as a frontrunner among development-stage mining companies, positioning the Company and our valued shareholders for success.

Key developments of 2023:

• Successful Exploration and Expansion: Building on our 2022 drilling success, we continued to focus on the definition and expansion of Zone X22. Our efforts here were instrumental in significantly contributing to the growth of our October 2023 Mineral Resource Estimate (“MRE”).

• Significant Mineral Resource Growth: The 2023 MRE showcased a substantial increase compared to our 2020 estimate – the Indicated category growing 126% in ounces and 127% in tonnes, with nearly all Inferred Resources from the 2020 MRE transitioning to the Indicated category.

• World-Class Project Scale: The Troilus gold-copper deposit now hosts one of the largest undeveloped gold resources in North America, with a gold equivalent mineral resource of 11.21 Moz* in the Indicated category and 1.80 Moz AuEq* in the Inferred category.

• Large Copper Resource: Copper represents a meaningful proportion of the Troilus deposit with a total of 729.5 million pounds grading 0.07% in the Indicated category.

• Permitting and Community Engagement: We've made steady progress with Federal and Provincial permitting processes, conducting successful ongoing public consultations with impacted communities and progressing the completion of our Environmental and Social Impact Assessment (“ESIA”).

*Indicated: 508.3 Mt at 0.69 g/t AuEq; Inferred: 80.5 Mt at 0.69 g/t AuEq. Cut off grades are based on $US 1,850/ oz Au; $4.25/lb Cu, and $23.00/ oz Ag; with an exchange rate of US$1.00: CAD$1.30. Recoveries varied with an average of 90% Gold, 92.5 % Silver and 91.8% copper without considering revenues from other metals. AuEq formulas are calculated as follows: Z87 Zone : AuEq = Au grade + 1.5628 * Cu grade + 0.0128 * Ag grade; J Zone : AuEq = Au grade + 1.5107 * Cu grade + 0.0119 * Ag grade; X22 Zone : AuEq = Au grade + 1.5628 * Cu grade + 0.0128* Ag grade; SW Zone : AuEq = Au grade + 1.6823 * Cu grade + 0.0124 * Ag grade.

SUCCESSFUL EXPLORATION PROGRAM

2023 reflected the focused and dedicated efforts of the exploration team, particularly with the success of the drilling program at Zone X22 which has become synonymous with some of the highest, thickest, and most continuous grades at Troilus.

• ~22,000 metres were drilled at X22, expanding the zone's mineral footprint from 300m to approximately 1km, and confirming a consistent pattern of continuous high-grade near-surface structures along this strike length.

• X22 returned among the highest results in Troilus’ history, including 1.80 g/t AuEq over 80m (X22-23-071), 19.9 g/t AuEq over 7m (X22-23-030), 103.8 g/t AuEq over 1m (X22-23-042) and 14.7 g/t AuEq over 7m (X22-23-067).

• X22 represents a small portion of our total drilling at Troilus, however this zone significantly contributed to our resource growth, and the proximity of this zone to the main mineral corridor made evident the potential impact it could have on the economic modeling of our project in the upcoming Feasibility Study.

UPDATED MINERAL RESOURCE ESTIMATE SHOWED GROWTH & SCALE

In October, we delivered an updated mineral resource estimate of 11.21 Moz AuEq (508.3Mt with an average grade of 0.69 g/t AuEq*) in the Indicated category and 1.80 Moz AuEq (80.5Mt with an average grade of 0.69 g/t AuEq*), marking an impressive 447% increase in Indicated AuEq ounces since our inception. This updated MRE firmly established Troilus among the largest undeveloped gold-copper deposits in North America. Furthermore, nearly all ounces in the MRE are categorized as 'open pit', and we saw nearly 100% conversion from Inferred to Indicated resources from the previous MRE, setting an excellent foundation for our upcoming Feasibility Study, expected this quarter.

Additional detail related to our 2023 MRE can be found HERE.

PERMITTING ADVANCEMENTS & PRIORITIY ON SUSTAINABLE DEVELOPMENT

In 2023, we reinforced our commitment to responsible project development by implementing a Sustainable Development Policy, which establishes a structured framework that aligns our operation with the highest environmental, social, and ethical standards. This new policy aims to foster prosperity among our employees and their families, support local communities, and encourage collaboration with local service providers. Beyond compliance, our efforts always aim to positively impact all our stakeholders.

The environmental permitting process steadily continued at both Federal and Provincial levels in 2023. Public consultations were successfully conducted by the Impact Assessment Agency of Canada and the Cree Nation Government in the local communities of Chibougamau, Mistissini, and Chapais, with insights and feedback from these meetings forming an important part of the ESIA. This report, underway by Stantec, is anticipated for completion by the end of 2024.

LOOKING AHEAD TO 2024

With a series of significant milestones on our horizon, 2024 is shaping up to be another transformative year for Troilus as we continue to steadily de-risk and advance our project towards production. Here’s what you can expect from us this year:

• Completion of a Feasibility Study expected in Q1 2024, including an inaugural Mineral Reserve estimate.
• Approximately 25,000 metres of drilling, including:
  • Expansion and definition drilling at select targets along the main mineral corridor.
  • Condemnation drilling to ensure the planned mine infrastructure locations are free of economically significant mineralization.
  • Continuation of exploration activities, including targeted drilling, at prospective regional targets.
• Completion of the Environmental and Social Impact Assessment by calendar year-end
• Continuous monitoring of the dynamic ESG landscape to identify new opportunities that will ensure the sustainable development of our project.

As we forge ahead, we express our sincere gratitude to our shareholders and all stakeholders for their ongoing support.

Sincerely,

Justin Reid Chief Executive Officer and Director Troilus Gold Corp.
