Drilling Commences At Columbus Gold's Four Metals Project

Vancouver, British Columbia, Canada. March 19, 2007. Columbus Gold Corporation (CGT: TSX-V) ("Columbus Gold" or the "Company") is pleased to announce that Black Pearl Minerals Consolidated Inc. ("Black Pearl") has commenced drilling at the Company's Four Metals Polymetallic property in Arizona. The core drilling program will consist of approximately 1,500 metres (m) (5,000 feet) and will focus on expanding the existing high-grade core of the deposit. The target is further development of a breccia-type pipe deposit similar to those in the productive Cananea district, located approximately 80 kilometers (50 miles) to the south in Mexico.

Surface and underground drilling by previous operators has returned numerous significant intercepts of copper, molybdenum, silver and gold. Significant intercepts drilled by previous operators and assayed for both copper and molybdenum include:

The Four Metals Property consists of 40 mineral claims, covering approximately 335 hectares (826 acres), located in the Patagonia District 16 kilometres (10 miles) north of Nogales, Santa Cruz County, Arizona. Subject to a net smelter royalty, Columbus owns a 50% interest in 16 claims and a 100% interest in 24 claims that make-up the property. Columbus has optioned its interest in the Four Metals Property to Black Pearl Consolidated Minerals Inc., for cash and common share payments over a four year period totaling US$300,000 and 600,000 shares respectively. Columbus will retain a 1.5% net smelter return royalty on certain claims that form the property subject to a US$500,000 buy-down on half of the royalty (0.75%) in favor of Black Pearl.

The property covers the Four Metals copper mine which is hosted within a crudely circular breccia pipe, approximately 300 m (1,000 feet) in diameter, intruding batholitic granite rocks. Mineralization consists of a shallow zone of supergene enriched chalcocite mineralization underlain by a larger body of primary mineralization containing chalcopyrite, pyrite, and molybdenite.
Four Metals has been intermittently investigated since the 1960's by Duval Copper, Noranda Mines and Metallic Ventures. The programs have included underground development, surface and underground core drilling, metallurgical test work, various investigations of a leach copper mining operation at the site and various historical resource estimates. Metallic Ventures also developed a conceptual mining scheme whereby the existing underground development, augmented by injection wells, could be utilized for an in-situ copper leaching operation.
