TROILUS LAUNCHES NEW 20,000 METRE DRILL PROGRAM FOLLOWING RELEASE OF POSITIVE

PRELIMINARY ECONOMIC ASSESSMENT

September 23, 2020 Toronto, Ontario – Troilus Gold Corp. (TSX: TLG; OTCQB: CHXMF) (“Troilus” or the

“Company”) has initiated a new 20,000 metre drill program at its 100% -owned Troilus property (the

“Troilus Project”) located near Chibougamau, within the Frotêt-Evans Greenstone Belt in Quebec, Canada.

The program will be completed through the remainder of 2020 with the objective being to upgrade current

mineral resource estimates and continue the expansion and exploration of mineralization across the

Troilus property, following the discovery of the Southwest Zone (“SWZ”) earlier this year (see Figure 1).

A total of 80,500 metres of drilling since 201 8 (see Figure 2) has delivered a total estimated indicated

mineral resource of 4.96 Moz AuEq (177 Mt with an average grade of 0.87 g/t AuEq) and total estimated

inferred mineral resource of 3.15 Moz AuEq (116.7 Mt with an average grade of 0.84 g/t AuEq) (see press

release dated July 28, 2020), the majority of which is derived from 72,000 metres of drilling proximal to

the Z87/Z87 South and the J Zones. Drilling at these zones will target upgrading the inferred mineral

resources within current open pit constraining shells to support the planned prefeasibility study, as well

as expand and extend near-surface mineralization to support the open-pit mine development scenario.

The Southwest Zone is located 3.5 kilometres southwest of Z87, parallel and directly adjacent to the access

road to the Troilus mine site . The Southwest Zone is characterized by the same dioritic host rock as Z87,

but having a more intense level of alteration and mineralization. An 8,500 metre drill program undertaken

in late 2019 and early 2020 delivered some of the best results ever drilled at the Troilus property, including

1.56 g/t AuEq over 73 metres in hole TLG-ZSW20-189 (see press release dated April 21, 2020), and outlined

a more than 500 metre mineralized trend that remains open along strike. The SWZ contributed 583,000

AuEq open pit inferred ounces (22.6 Mt with an average grade of 0.80 g/t AuEq) to the overall estimated

mineral resources (see press release dated July 28, 2020). Management believes successful drilling at the

SWZ has the potential to outline more near surface, higher grade material that could have a significant

impact on future engineering studies and production scenarios.

Justin Reid, Chief Executive Officer of Troilus Gold Corp., commented, “The drills are currently turning. We

anticipate that our team will be able to complete a minimum of 20,000 meters before the end of the year.

It is our expectation that drilling will aggressively continue through 2021 as well. Over the last three years,

our technical team has consistently delivered positive results by refining our structural model and

understanding of the Troilus deposit and controls on gold emplacement . This has resulted in a 142 %

increase to estimated indicated mineral resources and a 350% increase to estimated inferred resources

since we acquired Troilus in 2017 , thereby solidifying management’s belief that this project has the

potential to emerge as a long -life, open pit gold producer of scale located in one of the most favorable

mining jurisdictions on the globe.”

“The recent Preliminary Economic Assessment (“PEA”)* results confirm that the Troilus project, based on

the current estimated mineral resources, has the potential to deliver an after-tax IRR of 22.9% and NPV5%

of $576 million based on $1,475/oz gold increasing to 32.2% and $915 million at $1,750/oz gold and 38.3%

and $1,156 million at $1,950/oz spot gold prices over the course of a 22-year mine life with production

averaging 35,000 tonnes per day (see press release dated August 31, 2020). It is our expectation that with

more drilling we have the potential to identify additional resources that could further contribute to the

economic forecast of the future mine in terms of life of mine and/or daily production capacity.”

*Assuming a US$:C$ exchange of $0.74. All figures reported in US$ unless stated otherwise

Troilus remains underexplored and highly prospective. Extensive field exploration work undertaken this

summer across the +107,000 hectare Troilus property is currently being compiled to identify new

prospective targets. Assays of samples collected in the field are pending and will be updated in due course.

The Company has engaged the services of drilling company Forages Chibougamau Ltée . and 3 drills have

been mobilized on site.

Cautionary Note Regarding Forward-Looking Statements and Information

The PEA is preliminary in nature, includes inferred mineral resources that are considered too speculative

geologically to have the economic considerations applied to them that would enable them to be

categorized as mineral reserves, and there is no certainty that the PEA will be realized. Mineral resources

that are not mineral reserves do not have demonstrated economic viability. The PEA is subject to a number

of risks and uncertainties. See below and the Technical Report, once filed, for more information with respect

to the key assumptions, parameters, methods and risks of determination associated with the foregoing.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viabili ty; the

estimate of Mineral Resources in the updated Mineral Resource statement may be materially affected by

environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. There

is no certainty that the Indicated Mineral Resources will be converted to the Probable Mineral Reserve

category, and there is no certainty that the updated Mineral Resource statement will be realized.

This press release contains “forward- looking statements” within the meaning of applicable Canadian

securities legislation. Forward-looking statements include, but are not limited to, statements regarding the

impact of the planned drill program and results on the Company, the results of the PEA, statements

regarding the impact and implications of the economic statements related to the PEA, such as future

projected production, costs, including without limitation, AISC, total cash costs, cash costs per ounce,

capital costs and operating costs, the potential to extend mine life beyond the period contemplated in the

PEA, opportunity to expand the scale of the project, the Company’s understanding of the project; the

development potential and timetable of the project; the estimation of mineral resources; realization of

mineral resource estimates; the timing and amount of estimated future exploration; the anticipated results

of the Company’s planned 2020 drill program and their possible impact on the potential size of the mineral

resource estimate; costs of future activities; capital and ope rating expenditures; success of exploration

activities; the anticipated ability of investors to continue benefiting from the Company’s low discovery

costs, technical expertise and support from local communities and the anticipated timing of filing the

Technical Report. Generally, forward-looking statements can be identified by the use of forward- looking

Troilus has attempted to identify important factors that could cause actual results to differ materially from

those contained in forward-looking statements, there may be other factors that cause results not to be as

anticipated, estimated or intended. There can be no assurance that such statements will prove to be

accurate, as actual results and future events could differ materially from those anticipated in such

statements. Accordingly, readers should not place undue reliance on forward- looking statements. Troilus

does not undertake to update any forward- looking statements, except in accordance with applicable

securities laws.

Cautionary Note to U.S. Investors Concerning Estimates of Mineral Resources

Mineral resource estimates have been prepared in accordance with the requirements of Canadian

securities laws, which differ from the requirements of U.S. securities laws. The terms “mineral resource”,

“measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in

NI 43-101 and recognized by Canadian securities laws but are not defined terms or recognized under U.S.

securities laws. U.S. investors are cautioned not to assume that any part or all of mineral deposits in these

categories will ever be upgraded to mineral reserves. “Inferred mineral resources” have a great amount of

uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot

be assumed that all or any part of an “inferred mineral resource” will ever be upgraded to a higher

category. Under Canadian securities laws, estimates of “inferred mineral resources” may not form the basis

of feasibility or pre-feasibility studies. U.S. investors are cautioned not to assume that all or any part of an

inferred mineral resource exists or is economically or legally mineable. Accordingly, these mineral resource

estimates and related information may not be comparable to similar information made public by U.S.

companies subject to the reporting and disclosure requirements under the U.S. federal securities laws and

the rules and regulations thereunder.
