Greencastle Resources Ltd. Reports Drill Intersection of 24.54 m of 9.16 g/t Gold and 65.8 g/t Silver at Jewel Ridge, Nevada

Greencastle optionee, Golden Lake Exploration Inc. ("GLM") reported yesterday the discovery of a high-grade (gold-silver-lead-zinc) mineralized oxide zone at the Northeast Eureka target on the Company's Jewel Ridge gold property located near the town of Eureka, Nevada.

From surface, an intercept of 24.54 metres returned 9.16 grams per tonne (g/t) gold (Au), 65.8 g/t silver (Ag), 1.03% lead (Pb) and 1.90% zinc (Zn). This intercept is hosted in Hamburg dolomite and comprises both Carlin-type and CRD-type (carbonate replacement deposit) oxide mineralization.

A higher "bonanza" grade portion from 15.21 metres to 18.44 metres returned 3.23 metres averaging 57.16 g/t Au, 452.0 g/t Ag, 7.23% Pb and 11.99% Zn. This "bonanza" intercept is interpreted by the GLM geologists as similar to mineralization at the nearby historic Ruby Hill mine and can be described as an oxidized carbonate-hosted, structurally and lithologically controlled gold-silver (with associated lead-zinc) mineralization. The Jewel Ridge property hosts over a dozen past-producing mines and prospects over a four-kilometre strike on the Dunderberg-Windfall belt, most worked in the late 1800s for gold, silver and lead, from shallow oxide deposits. For more information, please see Golden Lake press release from yesterday.

"We are very encouraged by the results at Jewel Ridge, as we turn our attention to the recently acquired Seagrave and Mayflower properties, in the Red Lake and Rainy River Districts respectively, of NW Ontario. We are also very pleased with the exceptional performance of our primary holding, Deveron Corp., (FARM) where we own 11,000,000 common shares." commented Anthony Roodenburg, Greencastle, CEO.

Golden Lake can earn a 100-per-cent interest in Jewel Ridge, subject to certain royalties, by paying Greencastle $155,000 in cash, issuing five million Golden Lake Exploration shares, and spending $750,000 over three years. To date, Greencastle has received three million common shares of GLM.
