Cost, Cash Operating Costs ,Total Cash Cost, All-In Sustaining Cost, Expansion Capital and Capital Intensity,

which are not measures recognized under IFRS and do not have a standardized meaning prescribed by

Total Cash Costs are reflective of the cost of production. Total Cash Costs reported in the PEA include

mining costs, processing & water treatment costs, general and administrative costs of the mine, off-site

costs, refining costs, transportation costs and royalties. Total Cash Costs per Ounce is calculated as Total

Cash Costs divided by payable gold ounces.

All-in Sustaining Costs (“AISC”) and AISC per Ounce

AISC is reflective of all of the expenditures that are required to produce an ounce of gold from operations.

AISC reported in the PEAS includes total cash costs, sustaining capital, expansion capital and closure costs,

but excludes corporate general and administrative costs and salvage. AISC per Ounce is calculated as AISC

divided by payable gold ounces.

Cautionary Note Regarding Forward-Looking Statements and Information

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. 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.

The mineral resource estimates contained herein may be subject to legal, political, environmental or other

risks that could materially affect the potential development of such mineral resources. See the Resources

Report, once filed, for more information with respect to the key assumptions, parameters, methods and

risks of determination associated with the foregoing.

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

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 for more information with respect to the

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

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

securities legislation. Forward-looking statements include, but are not limited to, 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, statements with respect to Mineral Resource estimates, recovery

rates, IRR, NPV, mine life, CAPEX, payback period, sensitivity analysis to gold prices, timing of future studies

including the pre-feasibility study, environmental assessments (including the timing of an environmental

impact study) and development plans, the Company’s understanding of the project; the potential to extend

mine life beyond the period contemplated in the PEA, opportunity to expand the scale of the project, the

project becoming a cornerstone mining project in Quebec and Canada; 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; costs of future activities; capital and operating

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.

Generally, forward-looking statements can be identified by the use of forward- looking terminology such

as “plans”, “expects” or “does not expect”, “is expected”, “budget”, “scheduled”, “estimates”, “forecasts”,

“intends”, “contemplates”, “goal”, “continue”, “anticipates” or “does not anticipate”, or “believes”, or

variations of such words and phrases or statements that certain actions, events or results “may”, “could”,

“would”, “will”, “might” or “will be taken”, “occur” or “be achieved”. Forward-looking statements are

made based upon certain assumptions and other important facts that, if untrue, could cause the actual

results, performances or achievements of Troilus to be materially different from future results,

performances or achievements expressed or implied by such statements. Such statements and information

are based on numerous assumptions regarding present and future business strategies and the

environment in which Troilus will operate in the future. Certain important factors that could cause actual

results, performances or achievements to differ material ly from those in the forward- looking statements

include, amongst others, currency fluctuations, the global economic climate, dilution, share price volatility

and competition. Forward-looking statements are subject to known and unknown risks, uncertainties and

other important factors that may cause the actual results, level of activity, performance or achievements

of Troilus to be materially different from those expressed or implied by such forward- looking statements,

including but not limited to: the impact the COVID 19 pandemic may have on the Company’s activities

(including without limitation on its employees and suppliers) and the economy in general; the impact of

the recovery post COVID 19 pandemic and its impact on gold and other metals; there being no assurance

that the exploration program or programs of the Company will result in expanded mineral resources; risks

and uncertainties inherent to mineral resource estimates; the high degree of uncertainties inherent to

preliminary economic assessments and other mining and economic studies which are based to a significant

extent on various assumptions; variations in gold prices and other precious metals, exchange rate

fluctuations; variations in cost of supplies and labour; receipt of necessary approvals; general business,

economic, competitive, political and social uncertainties; future gold and other metal prices; accidents,

labour disputes and shortages; environmental and other risks of the mining industry, including without

limitation, risks and uncertainties discussed in the latest annual information form of the Company, in the

Technical Report and in other continuous disclosure documents of the Company available under the

Company’s profile at www.sedar.com. Although Troilus has attempted to identify im portant 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 updat e 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.
