Production, Shipment and Sale of Concentrates

June 4, 2007

Aurcana Corporation ("Aurcana or the Company") is pleased to announce that after the conclusion of mechanical mill equipment tests and the calibration of the metallurgical parameters, regular planned shipments and the sale of copper concentrates from the La Negra Mine, Queretaro State, Mexico have begun. Minera La Negra has shipped 120 tonnes of copper concentrate with a grade of 24.4% copper and 43 ounces/tonne of silver which represents a total of 64,500 pounds of copper and 5,160 ounces of silver, under its agreement with Trafigura S.A. de C.V. Based on current metal prices the approx gross value of the copper and silver contained in the concentrate is $285,245. The quality of concentrate exceeds the minimum specifications listed in the off-take agreement with Trafigura.

Since the Company re-started operations in April 2007, staff at the mine has been working diligently to ensure the mill obtains the correct metallurgical balance in all of the concentrates. The production and sale of the copper concentrates illustrates that the effort of the staff has been rewarded and the focus is now directed towards the production of a minimum 48% zinc concentrate which is close to being achieved.

The sale of the copper concentrate marks another significant milestone for the Company and the La Negra mine. In the last twelve months Aurcana has purchased, re-furbished and expanded the mill, re-started the mining operation and commenced the production and sale of concentrate.

With the completion of the mill start up at La Negra mine the Company is now moving some of its engineering group to the Rosario mine in order to proceed with the compilation of data relating to the historic reserves as well as confirming a number of high priority untested silver-zinc-lead targets elsewhere on the large (8500 ha) property. An on-site inventory of the mine, mill and town site is also being completed prior to finalizing the acquisition of the Rosario Mine from Grupo Mexico.

Aurcana is a Canadian junior mining company listed on the TSX Venture Exchange, symbol: AUN. The Company is currently in production and remains focused on the acquisition, development and operation of silver, zinc and copper mines with good infrastructure and ore reserves/resources that require minimal capital and time to re-start. 

Ron Nichols, P.Eng, a Director and Vice President of Exploration for Aurcana, and a Qualified Person as defined by National Instrument 43-101, supervised the preparation of the technical information in this release.
