Grayd Resource Corporation (TSX VENTURE:GYD) announces that a new resource calculation at its 100% owned La India gold project located in Sonora State, Mexico, resulted in 760,000 ounces of Measured and Indicated gold resource and 506,000 ounces of Inferred gold resource which represents a 16% and 35% increase, respectively, over the 2009 resource estimate. Grayd's President and Chief Executive Officer, Marc Prefontaine, said, "We've had a very successful year of drilling at the promising La India gold property, and the result is a significantly increased gold resource. Based on this success, we continue to aggressively explore the land package and are moving forward with a Preliminary Economic Assessment study on the project to determine the economics of developing an open pit, heap leach operation." Two drills are currently working on the 260 square kilometre La India property as part of a previously announced 15,000 meter drill program. Priority drill areas are three very large and prospective targets - La India, Tubos and Tarachi. A summary of Measured, Indicated and Inferred gold resource is presented below: TOTAL RESOURCE - 60% CLASSIFED AS MEASURED AND INDICATED 0.4 g/t Au Cut-off Measured + Indicated 26.8 million tonnes (mT) grading 0.88 g/t Au - 760,000 oz Au Inferred 19.7 mT grading 0.80 g/t Au - 506,000 oz Au 0.5 g/t Au Cut-off Measured + Indicated 20.2 mT grading 1.03 g/t Au - 665,000 oz Au Inferred 13.5 mT grading 0.96 g/t Au - 418,000 oz Au In February 2009, Grayd reported an Indicated resource of 23.8 mT grading 0.86 g/t Au or 654,000 oz gold and an Inferred resource of 13.5 mT grading 0.87g/t or 375,000 oz gold all at an 0.4 g/t Au cut-off grade. The 2010 resource estimate represents a 16% increase in the Measured and Indicated resources and a 35% increase in the Inferred resource over the 2009 resource estimate at a 0.4 g/t cut-off grade. OXIDE AMMENABLE TO HEAP LEACH WITH EXCELLENT METALLURGICAL RECOVERIES The majority of the resources at La India are oxide material, which tends to lend itself to a relatively simple recovery process. The oxide material contains predominantly gold mineralization with only minor amounts of silver. Column leach tests reported in August 2008 and November 2009 indicate an average gold recovery of 80% to 84% should be achievable in a heap leach processing operation if the rock is crushed to -25 mm (- 1 inch). Preliminary testing on sulphide material indicated that relatively high gold recovery may be achieved in a flotation concentrate. In two samples tested, 94% of the contained gold reported to the rougher flotation concentrate. Further test work on sulphide material is planned. A summary of Measured, Indicated and Inferred oxide resource follows: OXIDE RESOURCE - 61% CLASSIFED AS MEASURED AND INDICATED 0.4 g/t Au Cut-off - oxide only Measured + Indicated 21.6 mT grading 0.87 g/t Au - 603,000 oz Au Inferred 14.3 mT grading 0.82 g/t Au - 378,000 oz Au 0.5 g/t Au Cut-off - oxide only Measured + Indicated 16.6 mT grading 1.00 g/t Au - 530,000 oz Au Inferred 10.2 mT grading 0.97 g/t Au - 319,000 oz Au Last year's reported oxide resource was 20.3 mT grading 0.80g/t Au or 524,000 ounces of Indicated gold resource and 12.0 mT grading 0.84g/t gold or 322,000 ounces of Inferred gold resource both at a 0.4 g/t Au cut-off grade. The 2010 resource estimate represents a 15% increase in the Measured and Indicated resources and a 17% increase in the Inferred resource over the 2009 oxide resource estimate at a 0.4 g/t cut-off grade. ECONOMIC ASSESSMENT STUDIES TO BE COMPLETED IN 2010 A Preliminary Economic Assessment (Scoping Study) will now begin based on the new resource, metallurgical work completed by Kappes Cassiday & Associates and input from independent engineering, metallurgy and environmental consultants. The study is expected to be completed later this year. Environmental baseline studies have been initiated and will be continued through 2010. EXPLORATION AGGRESSIVELY CONTINUES Two drills are currently working on the 260 square kilometre La India property as part of a previously announced 15,000 meter drilling program that is budgeted to continue into late summer. Priority areas are three very large and prospective targets - La India, Tubos and Tarachi. Other areas with potential are being mapped and sampled with the intent of identifying additional priority drill targets. The resource calculation was completed by Independent Qualified person Gary Giroux, P.Eng. of Giroux Consultants, Vancouver, B.C. using Ordinary and Indicator Kriging of blocks 10x10x6 m in dimension. Independent Qualified Person, Matt Gray, Ph.D., C.P.G. of Resource Geoscience de Mexico, Hermosillo, Mexico was responsible for sample QA/QC, assay database verification, including comparing original assay certificates obtained independently from ALS Chemex Laboratories with the resource database, and geological model verification. Bulk density was determined by Kappes, Cassiday & Associates of Reno, Nevada, using specific gravity measurements on pieces of drill core. Hans Smit, P.Geo., VP Exploration for Grayd, is the Qualified Person that authored this press release. Input into the resource model included 33,399 samples from 510 reverse circulation and 102 diamond drill holes, a three-dimensional geological model developed by Grayd and a two-meter contour elevation model. Assays are from 1.5 m long reverse circulation samples drilled in dry hole conditions and HQ diameter core drill holes. The resource was calculated independently for 11 different rock domains in two zones. A total of 40 samples were capped to between 2.2 and 24.0 g/t Au with capping levels dependent upon the gold grade distributions within the different rock domains. Silver values as well as arsenic, copper, zinc and lead values are very low in the oxide material and not considered economically significant enough in the sulphide material to include in the resource calculation. A summary of the resource calculation at different cut-offs is attached. Maps and sections showing resource areas and exploration potential are posted on Grayd's website (www.grayd.com). Grayd Resource is a growth-oriented junior natural resource company focused primarily on exploring and developing a large land position in Mexico which is highly prospective for gold and silver mineralization. The Company's Officers and Directors are experienced in all aspects of mineral exploration, development and production and have been involved with several successful mining projects during the past 20 years.
