Silverstone Provides Three Year Silver Sales Forecast

October 10, 2007

Silverstone Resources Corp. ("Silverstone") is pleased to announce that The National Instrument 43-101 compliant technical reports prepared by Wardell Armstrong International, for Silverstone titled Technical Report on the Neves-Corvo Mine, Southern Portugal dated October 2007, and Technical Report on the Aljustrel Mine, Southern Portugal dated October 2007 have been filed on www.sedar.com .

The acquisition of the Neves-Corvo and Aljustrel silver, together with the existing silver purchase agreement with Capstone Mining's Cozamin mine (for further information see the Cozamin Mine technical report dated February 23, 2007 filed on www.sedar.com ) allows Silverstone to forecast the following silver sales as outlined in the table below:

Silver Sales Forecast

(1) Partial year of silver contracts
(2) Cozamin's silver production forecast is based on forecast production from it's 43-101 report, with silver recovery to copper concentrate estimated at 56%, with 91.7% of this silver paid by the smelter, and silver recovery to the lead concentrate estimated at 16% with 95% of this silver paid by the smelter. The Qualified person for the Cozamin forecast is Mr. Hugh Willson, P.Geo.,Vice President Exploration of Silverstone.
(3) Forecasts for Neves-Corvo silver production are based on the 10 year mine plan, presented in the 43-101 report. Recovery of silver from Neves-Corvo copper ore to concentrate is estimated at 35%, with 80% of this silver paid by the smelter. Silver recovery from Neves-Corvo zinc ores which commences production in 2009 is based on a silver recovery to a lead concentrate of 23% with 95% of this silver paid by the smelter. The Qualified person for the Neves-Corvo forecast is Mark L. Owen, Associate Director and Principal Geologist of Wardell Armstrong International.
(4) Forecasts for Aljustrel silver production are based on the 10 year mine plan presented in the 43-101 report on Aljustrel. Recovery of silver to a lead concentrate is estimated at 37.1%, with 95% of this silver paid by the smelter. The Qualified person for the Aljustrel forecast is Mark L. Owen, Associate Director and Principal Geologist of Wardell Armstrong International.              

The following tables set forth the Silverstone updated estimated Proven and Probable Reserves and the Mineral Resources for the Neves-Corvo and Aljustrel Mines as of December 31, 2006. There are no changes to the tables as stated in the September 17, 2007 press release except for clarification as to the basis of estimating the resources and reserves.

Current Proven and Probable Reserves for the Neves-Corvo mine are tabulated below:

Proven and Probable Mineral Reserves (1)

(1)  Reserves for the Neves-Corvo mine are estimated using cut off grades of 5.58% zinc and 1.91% copper.  The reserves are calculated by the mine's geologists and audited by Wardell Armstrong International (WAI). The Qualified Person for the 2006 Reserve estimate is WAI personnel Mark L. Owen, Associate Director and Principal Geologist, assisted by David Chilcott, Associate to WAI, and Senior Mining Engineer. The reserves are based on an effective mining width of 5 meters. Cut off grade is established by calculating the net sales value per percent metal considering mining and geological factors, and actual operating costs (43 Euro/tonne), development costs and royalties. Reserves in the copper zone are based on the value of copper only, and reserves in the zinc zone are based on the value of zinc only. The reserves were estimated as of December 31st, 2006. There are no known environmental, permitting, title, marketing etc issues which are expected to materially impact the estimate of reserves.

Current Proven and Probable reserves for the Aljustrel mine are tabulated below:

Proven and Probable Mineral Reserves (2)

(2)  The 2006 Aljustrel zinc Mineral Reserves are estimated using cut-off grades of 4.5% zinc and 4.0% zinc for the Feitais and Moinho deposits respectively. The copper mineral reserves are estimated using a 1.5% copper cut-off. Reserves are based on a calculated net sales value per tonne taking into account mining and geological factors including dilution and development, estimated operating costs of 25 Euros, and metallurgical recovery to derive a net sales value per percent. Reserves are calculated based on copper values only for copper ore and zinc values only for zinc ore. The reserves were calculated by SRK and audited by Wardell Armstrong International (WAI). The Qualified Person for the 2006 reserves and resources is Mark L. Owen, Associate Director and Principal Geologist, assisted by David Chilcott, Associate to WAI, and Senior Mining Engineer. The reserves are as of December 31st, 2006. There are no known environmental, permitting, title, marketing etc issues which are expected to materially impact the estimate of reserves.

The Measured, Indicated and Inferred mineral resources are presented below and include the mineral reserves tabulated above:

Measured and Indicated and Inferred Resources (3, 4)

(3)   Resources for Neves-Corvo Copper zones are reported at cut off grades of 2.0% copper for the copper zone, and 3.3% zinc for the zinc zone.  Three dimensional modeling methods and parameters were used in accordance with principles accepted in Canada.  Geological models were created using drill hole and underground data.  Statistical and grade continuity analyses were completed to characterize the mineralization and subsequently used to develop grade interpolation parameters.  Vulcan and Gemcom (Lombador and Corvo / Lombador Bridge only) mining software's were used to establish 3D block models and subsequent grade estimates.  Ordinary Kriging method of interpolation was used to estimate block grades.  Density block models were created by Ordinary Kriging of density measurements for all orebodies except Lombador and Lombador / Corvo Bridge where the Nearest Neighbor method of assignment was used.  Resources were classified according to the distance from closest sample point, with measured resources being < 17.5 meters from a sample point, indicated resources being between 17.5 to 35 meters from a sample point, and inferred resources being within 35 to 70 meters from a sample point. The resources are calculated by the mine's geologists and audited by Wardell Armstrong International (WAI).  
The Qualified Person for the 2006 resources estimates is WAI personnel Mark L. Owen, Associate Director and Principal Geologist, assisted by David Chilcott, Associate of WAI, and Senior Mining Engineer. The resources were estimated as of December 31st 2006.

(4)  The 2006 Aljustrel zinc Resources are reported at cut-off grades of 4.5% zinc, 4.0% zinc and 4.0% zinc for the Feitais, Moinho, and Estacao deposits respectively.  The copper mineral resources are reported at a 1.5% copper cut-off.  Three dimensional modeling methods and parameters were used in accordance with principles accepted in Canada.  Geological models were created using drill hole and underground data.  Statistical and grade continuity analyses were completed to characterize the mineralization and subsequently used to develop grade interpolation parameters.  Gemcom mining software was used to establish a 3D block models and subsequent grade estimates.  Ordinary Kriging was used to estimate block grades.  Average bulk densities were used to create density block models.  Measured resources have been defined as adjacent to existing stopes or within 15 meters of a sample point, indicated resources are within 15 to 40 meters of a sample point, and inferred resources are along the perimeters of the deposit where drill density is usually greater than 40 meters apart.  The resources were estimated by SRK (Feitais), AMEC (Moinho) and Lundin Mining Corporation (Esta��o) and audited by Wardell Armstrong International (WAI). The Qualified Person for the 2006 reserves and resources is Mark L. Owen, Associate Director and Principal Geologist, assisted by David Chilcott, Associate to WAI, and Senior Mining Engineer. The resources are as of December 31st, 2006.

Mr. Hugh Willson, P.Geo., Vice-President, Exploration of Silverstone, who is a "qualified person" under National Instrument 43-101, has reviewed and approved the technical aspects of this news release.
