Stingray Copper Inc.-Feasibility Study on Schedule: Metallurgical Update El Pilar Copper Project, Mexico

09/02/2009 8:37pm

Marketwired Canada


Stingray Copper Inc. (Stingray) (TSX:SRY)(TSX:SRY.WT) CEO, Peter Mordaunt
reports that, "Stingray's mandate to complete the Feasibility Study ("the
Study") of the El Pilar Oxide Copper Project located in Sonora, Mexico remains
on schedule for delivery in April. The metallurgical program has been completed
and we are pleased with the results as presented below in Table 1 and that are
being incorporated into the Study. This series of tests completed at Metcon
Research Inc. ("Metcon") in Tucson has been underway for more than a year and
the results are viewed as consistent with the earlier test work developed by
Noranda Mexico at the project."


The El Pilar Feasibility Study is well advanced. Third party consultants have
contributed their work for inclusion to the Study. M3 Engineering & Technology
Corp. ("M3") is overseeing the integration of all components of the Study to be
completed in April of 2009. Stingray has funded the majority of the budgeted
Study work. Several elements of engineering and government liaison (i.e.
permitting) are expected to continue seamlessly beyond the delivery of the
Study. This will ensure that the project continues to advance. Associated costs
are expected to be nominal but will maintain the timelines for an early start
for the El Pilar project.


The Feasibility Study is expected to be delivered at a time of lower commodity
prices. Volatile price swings make financial forecasting an artistic adventure.
As such, it is anticipated that the project will be presented in a conservative
commodity context. Stingray emphasizes that there are many countervailing
factors that may be beneficial at a time when copper prices have declined. As an
example, one of the principal operating costs of an SX-EW (solvent extraction -
electro winning) project is the cost of sulfuric acid. As an update to the
Corporation's last release (2008-16), the spot price of sulfuric acid, as
reported by the research firm PentaSul, has ranged from a high of US$650 per
tonne to a recent price of US$75 per tonne. Stingray is considering the
construction of a stand alone 600 tonne per day acid plant, as the declining
price of sulfur is outpacing the declining price of sulfuric acid. Current
weekly PEMEX quotes for sulfur are quoted at less than US$20 per tonne. One
tonne of sulfur produces 3 tonnes of sulfuric acid. This sulfur price is down
from US$510 per tonne as recently as October, 2008. Stingray expects that
operating cost reductions of this type, including fuel, will have positive
effects upon the viability of the El Pilar Project.


Mr. Mordaunt explains, "We expect to have many options available to advance the
El Pilar Project and add value for our shareholders, subject to a positive
Feasibility Study." Stingray has approximately $17 million of working capital,
principally cash held on deposit at a major Canadian Bank, with no debt and all
its current financial obligations met. This represents $0.29 of cash per
Stingray common share. Stingray will be able to preserve its cash and maintain
the opportunity that El Pilar represents for its shareholders for an extended
period. Stingray's annual expenditures can be easily scaled back to modest
levels while still advancing the project by completing internal detailed
engineering, thus reducing project risks. Many other trade off studies can be
completed as prices for equipment and materials decline in the current financial
landscape.


Metallurgical Update

Metcon has completed the preparation of 5 composite samples from drill cores
that are representative of the mine schedule (Year 1, Year 2, Year 3, Years 4-6,
Years 7-9), and performed the following metallurgical testwork: (For results of
the following items 1 through 3 see NR 2008 - 13)


1. bottle roll tests

2. mini column leach tests

3. open cycle column leach tests

4. locked cycle column leach tests

Testwork has progressed to the locked cycle column leach results of the five
composite samples as presented in Table 1 below. Metcon reports that the
following copper recoveries and associated sulfuric acid consumption can be
achieved at El Pilar. Additional metallurgical work for the Study will focus on
optimizing economic recovery by considering longer leach times and the cost of
additional sulfuric acid consumption as a function of declining sulfuric
acid/sulfur prices.
