Rimfire Appoints New President and CEO

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 4, 2007) - David Caulfield, in-coming Chairman of the Board of Directors is pleased to announce the appointment of Jason Weber, P.Geo., as the new President and CEO, and Director of Rimfire Minerals Corporation (TSX VENTURE:RFM). David has assumed the role of Chairman and Director of Business Development with responsibility for identifying new exploration opportunities for the company.

"We've come a long way from a small start-up in 1999," commented Mr. Caulfield. "I am very excited to be able to have Jason step into the leadership role. In turn, I can re-focus on what I love best about this business - identifying new exploration opportunities, developing business partnerships to further our exploration projects and pursuing the discovery of precious metal deposits."

"Jason has been a key member of our team since 1999. He is an experienced geologist with business savvy, has tremendous communications skills and is respected by his peers, our shareholders and the investment community," explained Mr. Caulfield. "The Board feels that Jason's youthful energy, enthusiasm and leadership skills are important elements in the future growth of our company."

As Manager, Corporate Communications, Jason was responsible for the development and implementation of Rimfire's marketing and investor relations strategies and played a large role in the strategic vision of the company.

"The current commodity boom has created an unprecedented demand for new grassroots mineral exploration and discoveries," said Mr. Weber. "Rimfire, with its experienced but youthful technical team is well positioned to continue to meet this demand. Our geoscience expertise, business model and capacity to advance multiple exploration projects give us a great competitive advantage that we will be working hard to maximize in the years ahead."

Since 1999, Rimfire has grown from two active projects and approximately $1.2 million in exploration annually to 12 projects with greater than $10 million in exploration exposure in 2007. A large part of this growth is due to David Caulfield's success as President and CEO in cementing innovative partnerships with some of the world's largest gold producers, mid-tier producers and junior exploration companies. Mr. Caulfield's new management role within Rimfire will be to focus on these partnerships and the opportunities that can be generated from them.

The Board of Directors would like to thank Henry Awmack for his service to the company as its Chairman. As a co-founder of Rimfire, Mr. Awmack has played an integral role in guiding the company and his contribution as Lead Director will continue to bring value to the company and its shareholders.
