"First, the Board of Directors would like to thank Matt for his insight and guidance in the formative stages of Dor? Copper and we wish him all the best in his future endeavours," stated said Mario Stifano, Executive Chairman of Dor? Copper. "We would also like to welcome Martha to the Board. Martha is a well-regarded leader and brings highly valuable and diverse expertise to the Corporation as we advance towards our goal of restarting mining operations in the Chibougamau mining camp."

Ms. Manuel is a member of the Neskonlith Band, which is one of the 17 communities within the Secwepemculecw (Shuswap territory) in British Columbia.

In 2019, Martha received the Michelle Pockey Leadership Award.

She also received the Trailblazer Award through Women in Mining Canada at the PDAC conference in Toronto in March 2020.

Dor? Copper also announces that it has granted Ms. Manuel an aggregate of 45,000 incentive stock options (the "Options"), having an exercise price of $0.79 per share.

About Dor? Copper Mining Corp.

Dor? Copper Mining Corp. is a copper-gold explorer and developer in the Chibougamau area of Qu?bec, Canada. The Corporation is focussed on implementing its hub-and-spoke development strategy by advancing its key high-grade copper-gold brownfield projects towards a restart of operations. Our goal is to achieve an annual production of 60 M lbs of copper equivalent (or 100,000 oz gold equivalent).

The Corporation has consolidated a large land package in the prolific Lac Dor?/Chibougamau and Joe Mann mining camps that has produced 1.6 billion pounds of copper and 4.4 million ounces of gold¹. The land package includes 13 former producing mines, deposits and resource target areas within a 60-kilometre radius of the Company's 2,700 tpd mill (Copper Rand Mill).

Dor? Copper plans to deliver a PEA of its hub-and-spoke model in late 2021. Currently, the Corporation is completing a 30,000-metre drilling program at its Corner Bay (Cu-Au) project, of which approximately 19,000 meters will be included in an updated mineral resource estimate expected in Q3 2021.
