FORWARD LOOKING STATEMENTS
Developing Canada’s Premier Copper-Gold Mine 2
The information provided in this presentation is not intended to be a comprehensive review of all matters and developments concerning Western Copper and Gold Corporation and its subsidiaries
(collectively, the “Company”). This document should be read in conjunction with all other disclosure documents of the Company. No securities commission or regulatory authority has reviewed the
accuracy or adequacy of the information presented herein.
Statements contained in this presentation that are not historical fact are “forward-looking statements” as that term is defined in the United States Private Securities Litigation Reform Act of 1995 and
“forward-looking information” as that term is defined in National Instrument 51-102 of the Canadian Securities Administrators (collectively, “forward-looking statements”). Forward-looking statements
in this presentation include, without limitation, statements regarding mineral reserve and resource estimates, planned exploration and development activities, corporate objectives, the economic
prospects of the Company’s projects, the Company’s future plans or future revenues, and timing of development, or potential expansion or improvements. Such forward-looking statements are based
on certain assumptions that the Company believes are reasonable, including, without limitation, with respect to any mineral reserve or resource estimate, the key assumptions and parameters on which
such estimates are based, prevailing and projected market prices and foreign exchange rates, projected capital and operating costs, continued availability of capital and financing, availability of
equipment and personnel required for construction and operations, the Company not experiencing unforeseen delays, unexpected geological or other effects, equipment failures, permitting delays, and
general economic, market or business conditions. Forward-looking statements are subject to known and unknown risks and uncertainties which could cause actual results to differ materially from
estimated results. Such risks and uncertainties include, but are not limited to, the Company’s ability to raise sufficient capital to fund development; changes in general economic conditions or financial
markets, changes in prices for the Company’s mineral products or increases in input costs; uncertainties relating to interpretation of drill results and the geological continuity and grade of mineral
deposits; that mineral resources and reserves are not as estimated; risks related to cooperation of government agencies and First Nations in the exploration and development of the property; litigation;
legislative, environmental and other judicial, regulatory, political and competitive developments in Canada; technological and operational difficulties or inability to obtain permits encountered in
connection with exploration and development activities; labor relations matters, and changing foreign exchange rates, all of which are described more fully in the Company’s filings with the applicable
regulatory agencies. The Company expressly disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise,
except as required by applicable securities legislation.
Cautionary Note to U.S. Readers/Investors: The United States Securities and Exchange Commission (the “SEC”) permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral
deposits that a company can economically and legally extract or produce.
We use certain terms in this presentation, such as “measured”, “indicated”, and “inferred” “resources”, that the SEC guidelines strictly prohibit U.S. registered companies from including in their filings
with the SEC. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and their economic and legal feasibility. It cannot be assumed that all or part of an inferred mineral
resource will ever be upgraded to a higher category. Readers are cautioned not to assume that all or any part of an inferred mineral resource exists or is economically or legally mineable. U.S. investors
are urged to consider closely the disclosure in the Company’s Form 40-F, which may be obtained from the Company or from the SEC’s website at www.sec.gov/edgar.shtml.

THE WORLD NEEDS A LOT MORE COPPER
DRIVERS FOR COPPER DEMAND GROWTH:
▪ Economic Stimulus: Post-COVID global
stimulus will result in copper demand for
infrastructure
▪ Electrification: Electric vehicles and electric
utilities will add 6-9 Mt of copper demand by
2040
▪ Decreasing Production: Closures due to
COVID, lower grades, and lack of new
investment have led to lower copper
production

5 million tonne deficit equivalent to annual production of
= 65 new Casino mines!!!

7. TSX : WRN I NYSE AMERICAN : WRN
THE WORLD NEEDS MORE LARGE GOLD DEPOSITS
▪ Few discoveries: very few new large gold
discoveries
▪ Low reserves: major gold companies’
reserves are decreasing
▪ Look to copper-gold: a number of the
largest gold mines are copper-gold deposits
like Casino (Grasberg, Boddington, Cadia,
etc.)

“And the principle of any mining is, your revenue is in your orebody. If you
start with a high quality orebody, it doesn’t have to be high grade; it can be
lower grade in a pit with no strip ratio.”
~ Mark Bristow, CEO, Barrick Gold*
“…we’ll look at gold and copper opportunities but remember, it’s got to add
value, add to mine life, take us down the cost curve and be in a jurisdiction
where we can manage the social-political risk…”
~ Gary Goldberg, Fmr CEO, Newmont Goldcorp*

NOTES
“2020 Resource”:
• See news release dated July 14, 2020.
• The Mineral Resources have an effective date of 3 July 2020 and the estimate was prepared using the definitions in CIM Definition Standards (10 May 2014).
• All figures are rounded to reflect the relative accuracy of the estimate and therefore numbers may not appear to add precisely.
• Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
• Mineral Resources for leach material are based on prices of US$2.75/lb copper, US$1500/oz gold and US$18/oz silver
• Mineral Resources for mill material are based on prices of US$2.75/lb copper, US$1500/oz gold, US$18/oz silver, and US$11.00/lb moly.
• Mineral Resources are based on NSR cut-off of C$5.46/t for leach material and C$5.70/t for mill material.
• NSR value for leach material is as follows:
• NSR (C$/t) = $12.65 x copper (%) + $41.55 x gold (g/t) + $0.191 x silver (g/t), based on copper recovery of 18%, gold recovery of 66% and silver recovery of 26%.
• NSR value for hypogene sulphide mill material is:
• NSR (C$/t) = $60.18 x copper (%) + $41.01 x gold (g/t) + $214.94 x moly (%) + 0.355 x silver (g/t), based on recoveries of 92.2% copper, 66% gold, 50% silver and 78.6% moly.
• NSR value for supergene mill material is:
• NSR (C$/t) = $65.27 x recoverable copper (%) + $42.87 x gold (g/t) + $142.89 x moly (%) + 0.425 x silver (g/t), based on recoveries of 69% gold, 60% silver and 52.3% moly.
Recoverable copper = 0.94 x (total copper – soluble copper).
• Mineral Resources are reported in relation to a conceptual constraining pit shell in order to demonstrate reasonable prospects for eventual economic extraction, as required
by the definition of Mineral Resource in NI 43-101; mineralization lying outside of the pit shell is excluded from the Mineral Resource.
• AuEq and CuEq values are based on prices of US$2.75/lb copper, US$1500/oz gold, US$18/oz silver, and US$11.00/lb moly, and account for all metal recoveries and
smelting/refining charges.

each of whom is a qualified person pursuant to National Instrument 43-101 ("Qualified Person")
• Mineral Resource Cut-off grades:
• Supergene & Hypogene Zones at CuEq cut-off 0.25%
• Leached Cap / Oxide Zones at Cut-off Au 0.25 g/t
• No discount for metallurgical recovery in contained metal figures
• "Long Term Metal Prices" were based on typical analyst projections of long term metal prices and $CAN:$US exchange rates when the feasibility study was issued.
• Capital and operating cost projections based on a foreign exchange rate of C$1.00 = US$1.00
“Canadian Creek Summary Report”:
• Technical report entitled "Summary report on the Canadian creek property – Whitehorse mining district, Yukon territory" dated May 4, 2017, a copy of which is
available on the Company's website at www.westerncopperandgold.com.
• Prepared by R.J. (Bob) Johnston, P. Geo
Other technical information in this presentation is based on the following key assumptions:
• Copper equivalent calculations in this presentation are based on: US$2.00/lb copper; US$875/oz gold; US$11.25/lb molybdenum; and US$11.25/oz silver, US$0.85/lb
zinc, US$4.00/lb antimony, US$0.80/lb lead.
• Technical information regarding the Casino Project contained in this presentation is based on the Casino Feasibility Study prepared by or under the supervision of the
Qualified Persons noted above.
• Economic results using "Spot Prices" are derived by adjusting the Casino Feasibility Study financial model (Feasibility Study Table 22-5) for commodity prices and
foreign exchange rates representative of current conditions only. There has been no change to mineral resource or mineral reserve estimates or the capital cost
contained in the Feasibility Study. The capital cost has not been adjusted for changes in Canadian to US exchange rate.
