Aurcana Corporation: Mineable Reserves at Alacran Deposit Increase by 98 Per Cent, Work Underway on Resource Estimates for 7 Other Deposits

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Jan. 18, 2008) - Aurcana Corporation ("Aurcana" or the "Company") (TSX VENTURE:AUN) is pleased to report that it has received a positive NI 43-101 compliant reserve calculation on the Alacran deposit of the La Negra mine, Queretaro State, Mexico from its independent consultants, Wardrop Engineering Inc. (Wardrop). A copy of the Wardrop report will be filed at www.SEDAR.com within 45 days. Aurcana is very encouraged by the tonnage increase which is a result of the present favourable metal price environment. Other known deposits at La Negra are expected to show similar increases in tonnage.

Highlights of the 43-101 Report

- 434,825 tonnes of mineable reserves, a 98% increase from historically reported reserves

- 36,900 tonnes of mined ore stored in stockpiles ready for processing

- 181,239 tonnes of inferred resources in addition to the reserves, not reported historically

The Wardrop reserve estimate for the Alacran deposit, (using a $30 per tonne NSR cut-off) is 434,825 tonnes which represents a 98% increase from the historically reported reserve in 2000. The Wardrop calculation also determined a present day NSR value which follows a similar format used by the previous owner accounting for dilution and metallurgical recoveries, and uses metal prices of $12.00 per ounce of Silver (Ag), $2.80 per pound of Copper (Cu), $1.40 per pound of Zinc (Zn) (No value was assigned to the Lead (Pb) content since no lead concentrate is being produced from the Alacran ore). It also factors in concentrate sale terms as negotiated by Aurcana with the concentrate buyer.

The Wardrop resource calculation also includes an inferred resource category in the estimate which was not included in the previous owners' historically reported reserve estimate. The inferred category included in the table above is a result of a compilation of historical drill holes, and underground sampling completed by Aurcana.

The above reserve estimate is based on ore that was present in the Alacran deposit as of May 31, 2007. Subsequent mining from the reserve blocks that formed a part of the reserve estimate has produced a total of:

----------------------------------------------------------------------
Mined ore (i) 60,702 95.21 0.29 1.11 1.15 $ 69.45
----------------------------------------------------------------------
(i) Based on mine production records, June 1, 2007 to January 8, 2008


The Alacran deposit, where the Company has focused its mining, accounted for approximately 18% of the historical non-compliant reserve at the time of purchase by Aurcana. Combined with the Alacran deposit, another seven zones comprise approximately 84% of the historically reported reserves in 2000. With the receipt of the Alacran reserve study, the Company is proceeding to update the historical reserves within these other seven areas of the mine and based on the results experienced in the Alacran area Aurcana anticipates similar improvements in tonnages, however, the precise increases will require detailed studies as was done by Wardrop on the Alacran area. Work is already progressing well in one area, Monica, where a total of 863 metres of diamond saw cut channel samples have been taken and are being analyzed. These samples are being combined with the historical database.

Wardrop also completed the following resource estimates for the Alacran deposit using different NSR cut-off levels. These estimates indicate that with additional mine planning it may be possible to selectively mine the deposit, and thus achieve a higher overall NSR value.

Aurcana is very encouraged by the Wardrop study. The engineering department is currently optimizing a mining plan that targets an operating profit margin of US$40 per tonne based on an NSR value less operating costs of $35 per tonne.

The Company is also continuing to explore in the Alacran area with work underway to develop access to target areas. A diamond drill program is currently testing the Cristo Rey and Breccia Zones in an effort to expand and upgrade the reserves/resources in these areas. Other priority targets include additional drilling on the Trinidad 1 (stope 1980), 2, and 3 manto zones. Drilling will also commence early this year on the Monica zone where recent underground mapping and diamond saw cut channel samples have returned encouraging results.

Aurcana remains committed to becoming a mid tier base-precious metals producer. The Company is focused on the acquisition, development and operation of silver, zinc and copper mines with good infrastructure and ore reserves/resources requiring minimal time to re-start. With a 1,000 tonnes per day production currently established, aggressive exploration programs underway on two properties, a positive outlook for the price of commodities and a strong balance sheet, the future is very promising for Aurcana and its shareholders.
