Title: Atna and Canyon Agree to Merge

VANCOUVER, BC and Golden, CO, November 19, 2007 -- Atna Resources Ltd. ("Atna") (TSX:ATN) and Canyon Resources Corporation ("Canyon") (AMEX:CAU) jointly announced today a transaction whereby Atna will acquire all of the issued and outstanding shares of common stock of Canyon for a total value of approximately C$25.3 (US$25.9) million.

Atna and Canyon believe that the combination will benefit shareholders of both companies by creating a strong platform for growth with the following characteristics and synergies:

• A multi-million ounce gold company highly leveraged to gold price.
• Near term gold production from Briggs and Reward projects to complement development at Pinson.
• Upside opportunity from complementary pipeline of gold exploration and development projects.
• Focus on gold in the western U.S.
• Exceptional management team with complementary skills and experience.
• Size and financial strength to ensure continued growth
• More than C$13.7 (US$14) million cash in hand

Under the proposed transaction, Canyon shareholders will receive 0.32 common shares of Atna for each share of common stock of Canyon. Based on Friday's closing price of C$1.68 for Atna, the consideration is valued at C$0.54 (US$0.55) per Canyon common share. The consideration represents a premium of 44.9% to Canyon's closing share price on November 16, 2007, or a 42.1% premium based on the 20-day volume weighted average share prices for both companies from that date.

Atna and Canyon have entered into an Agreement and Plan of Merger. The Board of Directors of Canyon has agreed to support the proposed transaction and recommends that Canyon shareholders vote in favor of it. Management and Directors of Canyon have entered into support agreements with Atna under which they have agreed to vote in favor of the transaction.

David Watkins, President and CEO of Atna, said, "The transaction complements Atna's exciting development opportunity at the Pinson gold mine in Nevada with Canyon's near-term production projects at the Briggs Gold Mine in California and the Reward Project in Nevada. Canyon also brings a number of complementary exploration and development properties, which combined with Atna's portfolio of prospects, creates an impressive pipeline of opportunities in the merged entity."

"Another key benefit to both Atna and Canyon shareholders is the creation of a powerful and balanced team of experienced mining professionals, which results from combining the complementary skill sets of the people in both companies. Jim Hesketh and I worked together for 14 years dating back to our days at Cyprus Amax in the 1990s. Jim has been a director of Atna for six years and is in a unique position to understand and appreciate the value of our assets and the growth platform we are creating."

Jim Hesketh, President and CEO of Canyon, added, "This transaction provides an attractive premium to Canyon's shareholders, while affording them the opportunity to participate in a growth-focused gold company through their investment in Atna. The combined company will have the financial strength and access to capital markets to advance Briggs and Reward into production. I am also excited about working with David Watkins again. I know him to be a superb individual who has a high level of integrity. I feel this is an excellent opportunity for Canyon."

Atna intends to advance the Briggs and Reward projects into production in 2008-2009. Canyon is forecasting production from the projects to reach 60,000 - 80,000 oz per year at a cash cost of US$400 - 450 per ounce.

The gold mineralization in the two companies is reported in accordance with Canadian (Atna) and US (Canyon) regulatory requirements:

Cautionary Note to US Investors
This press release and other information released by Atna uses the terms "resources", "measured resources", "indicated resources" and "inferred resources". United States investors are advised that, while such terms are recognized and required by Canadian securities laws, the SEC does not recognize them. Under United States standards, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. Mineral resources that are not mineral reserves do not have demonstrated economic viability. United States investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into reserves. Inferred resources are in addition to measured and indicated resources. Further, inferred resources have a great amount of uncertainty as to their existence and as to whether they can be mined legally or economically. It cannot be assumed that all or any part of the inferred resources will ever be upgraded to a higher category. Therefore, United States investors are also cautioned not to assume that all or any part of the inferred resources exist, or that they can be mined legally or economically.
