Grayd Reports Promising Metallurgical Testwork From Tarachi Gold Porphyry

27/04/2011 4:42pm

Marketwired Canada


Grayd Resource Corporation (TSX VENTURE:GYD) ("Grayd") reports an average gold
recovery of 79% from nine cyanide bottle roll leach tests on material from the
newly discovered Tarachi gold porphyry.


The cyanide bottle roll leach tests were completed by Kappes Cassiday and
Associates (KCA) of Reno, Nevada. Each sample tested was a composite made from
the assay rejects of 4 samples within a specified range from individual drill
holes. Samples were chosen to provide a distribution in area, depth and gold
grade. All tests were performed on 1 kilogram of material pulverized to 0.075 mm
and were leached for 4 days. Individual test results ranged from a low of 61%
gold recovery to a high of 95%. Cyanide consumptions of 0.09 to 0.70 kg/tonne
were relatively low.


Marc Prefontaine, President and CEO of Grayd, stated: "These metallurgical
results are very positive as they indicate the majority of the gold at Tarachi
can be recovered by relatively simple processes. Further work will be undertaken
to evaluate recovery versus particle size. By the end of this month, 3 drills
will be working on the property to continue testing this very large system."

Mineralization at Tarachi is similar to porphyry-style gold systems globally.
Gold porphyries are characteristically of moderate to low grade, but contain
high tonnages that support large mining operations. World-class gold porphyries
of this type occur in the Maricunga belt of Chile, where over 60 million ounces
of gold have been identified in 14 separate deposits.


The La India property is located in the prolific Mulatos gold belt of Mexico's
Sonora State. Tarachi is located 10 kilometers north of the resource area that
was analyzed in a recently reported Preliminary Economic Assessment (PEA), and
represents a separate gold-rich mineral system. Results of the PEA, reported on
October 21, 2010, show a 51% internal rate of return, a US$187 million net
present value (pre-tax, 5% discount rate), a 9-year mine life and nearly 850,000
ounces of gold produced with an open pit mine and heap leach extraction
facility. Grayd has initiated feasibility level work on this resource.


Hans Smit, P.Geo., VP Exploration for Grayd, is the Qualified Person directing
the exploration at La India. Samples are sent to the ALS Chemex facility in
Hermosillo for sample preparation, and then to the ALS Chemex laboratory in
Vancouver for gold assay and ICP. QA/QC procedures used include assay standards
and blanks. Test work described in this news release was performed by Kappes
Cassiday and Associates in Reno, Nevada.
