Silverstone Continues to Expand Mineralized Zones at the Copala Silver-Gold Project, Sinaloa State, Mexico
VANCOUVER, BRITISH COLUMBIA -- (MARKET WIRE) -- June 19, 2007 -- Silverstone Resources Corp. ("Silverstone") (TSX VENTURE: SST) is pleased to report results from 14 additional drill holes (1355m HQ core drilling) from the company's ongoing Phase IIA drilling on the Copala Project. Copala is located 60km ENE of the city of Mazatlan, Sinaloa State, Mexico. All of the drill holes were targeted on mineralization in the Clemens and El Muerto zones on the Animas Refugio vein. A summary of the results from Holes SC-07-72 through SC-07-86 is presented in the following table.
HIGHLIGHTS (True Widths)
- SC-07-72: 11.33m grading 1.65g/t gold and 288g/t silver
- SC-07-73: 7.75m grading 1.86g/t gold and 227g/t silver
- SC-07-74: 6.23m grading 1.60g/t gold and 189g/t silver
- SC-07-75: 5.31m grading 1.69g/t gold and 204g/t silver
- SC-07-83: 3.24m grading 2.31g/t gold and 259g/t silver

- (i)True widths are estimated by correcting for the strike and dip of the
vein and the bearing and inclination of the drill hole.
- Holes SC-07-77 and SC-07-79 were anomalous and all cut the Animas-
Refugio vein near the surface.
- Hole SC-07-80 is being re-assayed and the results are expected next
month.
- Drill hole location maps are found on Silverstone's website at
www.silverstonecorp.com.
These data show that the silver-gold mineralization in both the Clemens and El Muerto zones is open along strike and down dip. There is excellent potential for both underground and open pit development on this vein.
Silverstone management is very enthused over the drilling results to date and has committed to the following work:
- Continued drilling of mineralization on the Animas-Refugio vein with the addition of a second drill rig.
- Preliminary metallurgical testing of mineralization from the Clemens and El Muerto zones.
- Completion of a third party mineral resource estimate by the 4th quarter of 2007.
- Continued exploration and drilling of other silver-gold mineralized veins at Copala.
The Animas-Refugio vein has a strike length greater than 2.4km within mining claims controlled by Silverstone. Within this strike length, there are four zones that have historic workings. Prior to drilling the Clemens zone, Silverstone drill tested the San Carlos, El Muerto and Clavo San Francisco zones. To date, Silverstone has drilled 91 holes totaling 9,042m at Copala. Previous results were presented in news releases dated October 11, 2006 and March 6, 2007.
Samples were assayed by ALS Chemex in Vancouver. Blank, standard and duplicate pulp samples have also been assayed by ALS Chemex and duplicate core samples have been sent to SGS Lakefield in Toronto, Ontario. The results for these QA/QC samples have been acceptable in the mineralized intervals and additional QA/QC analyses are in progress.
Hugh Willson, Vice President of Exploration for Silverstone and a qualified person under NI 43-101, has reviewed the contents of this news release and supervised the Copala Project for Silverstone since its inception.
