PRESS RELEASE

DORÉ COPPER ANNOUNCES CLOSING OF C$11 MILLION PRIVATE PLACEMENT

OF FLOW-THROUGH SHARES, INCLUDING FULL EXERCISE OF AGENTS'

OPTION

Not for distribution to United States news wire services or for dissemination in the United States

Toronto, Ontario – February 18, 2021 – Doré Copper Mining Corp. (the "Corporation" or "Doré Copper")

(TSXV: DCMC; OTCQB: DRCMF; FRA: DCM) is pleased to announce that it has closed its previously

announced "best efforts" private placement (the "Offering"), pursuant to which the Corporation sold an

aggregate of 12,221,000 common shares of the Corporation that will qualify as "flow-through shares" within

the meaning of subsection 66(15) of the Income Tax Act (Canada) (the "Flow-Through Shares") at a price

of C$0.90 per Flow-Through Share for aggregate gross proceeds of C$10,998,900, including the full

exercise of the agents' option. With the closing of this Offering, the Corporation now has 53,158,668

common shares outstanding.

Ernest Mast, President and CEO, stated: “With this funding, Doré Copper 's cash balance totals

approximately C$16 million, providing ample funds for the Corporation to continue exploration and advance

its key high-grade copper-gold projects in Chibougamau, Québec to a PEA (Preliminary Economic

Assessment) later this year that envisions a hub-and-spoke operation feeding a centralized mill. We are

also pleased to announce that several established mining entrepreneurs were involved in the Offering,

resulting in a meaningful share position in the Corporation. These investors have indicated that they share

the Corporation's vision of building a new and significant Canadian-based copper-gold mining company

and will help in providing strategic advice to the Corporation in achieving that vision.”

Cormark Securities Inc. and Paradigm Capital Inc. acted as agents (the "Agents") in connection with the

Offering pursuant to the terms of an agency agreement dated February 18, 2021. In consideration for their

services in connection with the Offering, the Corporation paid the Agents a cash commission equal to

$659,934 representing 6% of the aggregate gross proceeds from the sale of Flow-Through Shares.

The Corporation will use an amount equal to the gross proceeds received by the Corporation from the sale

of the Flow-Through Shares, pursuant to the provisions in the Income Tax Act (Canada), to incur eligible

"Canadian exploration expenses" that qualify as "flow-through mining expenditures" as both terms are

defined in the Income Tax Act (Canada) (the "Qualifying Expenditures") on or before December 31,

2022, and will renounce all of the Qualifying Expenditures in favour of the purchasers of the Flow-Through

Shares effective December 31, 2021. The Corporation will shortly announce its drilling plans for the next

two quarters based on the funds available from the recent financings.

The Offering was made by way of private placement in Canada pursuant to applicable exemptions from the

prospectus requirements under applicable Canadian securities laws. The securities issued under the

Offering are subject to a hold period under applicable Canadian securities laws which will expire on June

19, 2021. The Offering is subject to final acceptance of the TSX Venture Exchange.

The securities offered have not been, nor will they be, registered under the United States Securities Act

of 1933, as amended, or any state securities law, and may not be offered, sold or delivered, directly or

indirectly, within the United States, or to or for the account or benefit of U.S. persons, absent registration

or an exemption from such registration requirements. This news release does not constitute an offer to sell

or the solicitation of an offer to buy nor shall there be any sale of securities in any state in the United

States in which such offer, solicitation or sale would be unlawful.
