Blackrock Silver Corp. announced initial drill results from the scout- drilling program on the Tonopah North project located in West Central Nevada, adjacent to the Company's Tonopah West project along the Walker Lane trend. Blackrock has completed ten reverse circulation drill holes in the Tonopah North project as part of a scout-drilling program to test for the margins of the Tonopah caldera system.

Drill holes targeted the ring structure which plays host to silver and gold mineralization on the Tonopah West project located immediately to the south and east; key structural projections from the Tonopah West project; and lithium potential within the Siebert Tuff. All drill holes penetrated cover rocks known to host lithium deposits in the region including the TLC deposit, which is located within five kilometers of the drilling. A significant zone of lithium-bearing material was intersected.

Lithium values up to 852 ppm lithium within a 23-metre thick section of the Siebert Tuff was discovered. Drill hole TN22-006 returned the most significant lithium values to date. As a result, four additional drill holes are being planned adjacent to TN22-006 to target for higher grade lithium potential.

Drill holes TN22-007, -008, and -009 were completed in the East-West Pediment target along the interpreted northern margin of the caldera. Results from these drillholes are pending at this time. TN22-010 was drilled westward to intersect the interpreted ring structure farther to the west.

Assays are pending at this time. All sampling is conducted under the supervision of the Company's project geologists, and a strict chain of custody from the project to the sample preparation facility is implemented and monitored. The reverse circulation samples are hauled from the project site to a secure and fenced facility in Tonopah, Nevada, where they are loaded on to American Assay Laboratory's (AAL) flat-bed truck and delivered to AAL's facility in Sparks, Nevada.

A sample submittal sheet is delivered to AAL personnel who organize and process the sample intervals pursuant to the Company's instructions. The reverse circulation, and QA/QC samples are crushed and pulverized, then the pulverized material is digested and analyzed for Au using fire assay fusion and an Induced Coupled Plasma (ICP) finish on a 30-gram assay split. Silver is determined using five-acid digestion and ICP analysis.

Over limits for gold and silver are determined using a gravimetric finish. Data verification of the assay and analytical results are completed to ensure accurate and verifiable results. Blackrock personnel insert a blind prep blank, lab blank or a certified standard approximately every 15th to 20th sample.

In addition to gold and silver determinations, Blackrock completes multi-element geochemistry on all samples. A 0.5-gram split is prepared and digested in a five-acid solution and is analyzed using inductively coupled plasma optical emission spectroscopy. For lithium, detection limits are between 0.2 to 10,000 ppm.

Standardized material is inserted by AAL personnel and final results are reviewed with relation to the AAL standards.
