Aurcana Adds Over 500,000 Tonnes In Monica Zone
|Deposit Open To Depth|
Aurcana Corporation ("Aurcana" or the "Company") is pleased to report that it has received a positive NI 43-101 compliant resource calculation on the Monica deposit at the La Negra mine, Queretaro State, Mexico, from its independent consultant, GeoSim Services Inc. (GeoSim). The report estimates a measured and indicated resource of 587,698 tonnes in the Monica zone. A copy of the GeoSim report will be filed at www.SEDAR.com within 45 days.
The present resource estimate only considers data collected over a 200 meter vertical interval from the 2250 level down to the 2050 level. Sampling on the 2000 level has located the interpreted depth extension of the Monica deposit, and work continues in this area in order to further define additional resources. A diamond drill program is currently underway at Monica in order to expand the Zone to depth, as well as to provide infill holes within the resource blocks to help refine the mining plan.
Aurcana is very encouraged by the tonnage increase which is a result of a re-interpretation of the geometry of the Monica deposit, and the present favorable metal price environment. Other known deposits at La Negra are currently undergoing re-evaluations and are expected to contribute significantly to further increases to the overall tonnage present in the 23 known deposits at La Negra.
Highlights of the 43-101 Report
The GeoSim resource estimate for the Monica deposit, (using a $30 per tonne NSR cut-off) is 587,698 tonnes which represents a 1,115 % increase from the 48,300 tonnes of historical reported reserves in 2000. The GeoSim calculation also determined a present day NSR value which follows a similar format used by the previous owner in accounting for metallurgical recoveries, and uses metal prices of $13.50 per ounce of Silver (Ag), $2.85 per pound of Copper (Cu), $1.00 per pound of Zinc (Zn). (No value was assigned to the Lead (Pb) content since no lead concentrate is currently being produced from the Monica ore.) It also factors in concentrate sale terms as negotiated by Aurcana with the concentrate buyer.
The resource estimates contained in tables 1 and 2 are a result of a compilation of 45 historical drill holes, previous underground sampling and additional sampling carried out by Aurcana. A total of 3,702 underground channel sample composites were used in the resource calculation. All of this data was entered into a Surpac 3D model and the resource estimate was then completed based on the kriging method.
GeoSim also completed the following resource estimates for the Monica deposit using a $40 NSR cut-off level. This estimate indicates that with additional mine planning it may be possible to selectively mine the deposit, and thus achieve a higher overall NSR value.
About Aurcana Corporation:
Aurcana Corporation is a Canadian mining company listed on the TSX Venture Exchange, symbol AUN. The 80% owned La Negra silver-lead-zinc-copper mine in Queretaro State, Mexico operates at 1,000 tonnes per day and the 100% owned Rosario silver-lead-zinc-gold mine in southeast Sinaloa State, Mexico is forecast to commence production at a planned rate of 800 tonnes per day in 2009. The Company is currently carrying out aggressive exploration programs on both projects to increase historical reserves and resources and with success this could lead directly to expansion of production.
Aurcana, while committed to ongoing exploration and expansion of current operations, continues to seek and evaluate other high quality, producing or near producing projects. With the acquisition of any or all of these advanced stage projects, present and proposed cash flow will increase significantly.
