Richard Warke

Executive Chairman

Richard Warke is a Vancouver based mining executive and the Chairman of Arizona Mining Inc., an exploration and development company based in Canada. The company’s world class Taylor Deposit is a zinc-lead-silver carbonate deposit that is being aggressively drilled.

Alongside Arizona Mining, Richard Warke currently serves as Executive Chair of NewCastle Gold Ltd., a company focused on exploring its multi-million ounce gold deposit in California.

These businesses are part of the Augusta Group of Companies, a conglomerate that Richard founded in 2006 and comprised of Arizona Mining, NewCastle Gold Ltd. and Armor Minerals.

Richard has been responsible for the founding and success of several resource companies in the past. Previously in the Augusta Group was Augusta Resource Corporation, which sold for roughly $666 million in 2014, and Ventana Gold Corporation, which sold in 2011 for approximately $1.5 billion.

With more than 25 years of experience in the mining industry, Richard has been instrumental in raising over $1 billion dollars in equity for resource companies. Although his endeavors have primarily concentrated in the area of mining, Richard has also been involved with oil and gas, forestry, technology and manufacturing operations.

Richard Warke has established himself as a diligent and hardworking entrepreneur who is able to build successful and efficient mining operations. In addition, he is a sought-after voice in the mining industry who is often called upon by the media to offer industry guidance and expertise.

During a 2014 interview, when asked about what he has learned from his time in mining, Richard explained the importance of surrounding himself with like-minded, hard-working colleagues. “Like any business you cannot succeed unless you have a first class dedicated management team,” Richard explained. “People who know their craft and are not afraid to work together for a common cause. There is no doubt that any successes I have had would not have been possible without a full team effort.”

He is also outspoken on the topic of due diligence in regards to mining endeavors and advises those looking to expand into the sector to work in countries that have a positive attitude toward mining initiatives. Richard also reminds those within the industry to choose locations in jurisdictions that are politically stable.

Besides his experience in the mining sector, Richard also has businesses in the aviation and hospitality industries.
