Blackrock Silver Corp. announced final drill results from the Company's first scout exploration drill campaign on its 100% controlled Tonopah North project located in West Central Nevada along the Walker Lane trend. These results show the Tonopah North project has significant lithium potential over a considerable area.

A broad lithium zone has been intersected in all drill holes across the Tonopah North project area encompassing 5,200 acres (2,100 ha). The lithium bearing zone has an average thickness of 28.1 metres and has been drilled near the surface to a depth of 117.3 metres below the ground. Based on the drilling to date, the lithium zone is entirely within the Siebert Tuff, and has a similar profile to the lithium mineralization encountered at the TLC deposit located 3 kilo metres to the northwest.

The lithium bearing zone remains open in all directions. Highlights: Lithium values up to 1,217 ppm lithium have been intercepted in drilling, in addition to continuity of broad zones of mineralization up to 56.4 metres in thickness; The average thickness of the lithium bearing zone is 28.1 metres; The lithium bearing zone comes within 8 metres of the surface on the northeast portion of the property and has been intersected down to 117 metres below the surface. The mineralization is similar to the nearby TLC lithium deposit owned by American Lithium Corp.

which is located 3 kilometres to the northeast of the Company's land holdings. The company completed approximately 9,300 metres of drilling in twenty RC drill holes. The drilling originally was to test the gold and silver potential to the west and north of the Company's silver-gold resource area located at the Tonopah West project; however, drilling of the upper geologic units was required to reach the underlying precious metal targets.

All drill holes penetrated cover rocks known to host lithium deposits in the region including the TLC deposit, which is located within five kilometres of the drilling. A significant zone of lithium-bearing material was intersected. Lithium values up to 1,217 ppm lithium within a 23-metre thick section of the Siebert Tuff was discovered.

Dril holes TN22-001, -002, -007, -008 -010, -015 and TN22-016 did not return lithium values above the 400-ppm cut-off grade; however, these drill holes intersect significantly anomalous lithium bearing zones within the Siebert formation. TN22-001 encountered a 45-metre zone of anomalous lithium grading 113 ppm Lithium. Similarly, TN22- 002 encountered two 45 metre zones starting at the surface grading 158 ppm and 126 ppm lithium starting at 3 metres and 60 metres respectively.

TN22-003 encountered three anomalous lithium zones with the best one returning 216 ppm lithium over 88 metres. TN22-007, -008 and -009 were completed in the northern portion of the claim block. TN22-007 intersected 21 metres grading 57 ppm lithium within the Siebert Tuff.

TN22-008 cut a 113-metre zone of anomalous lithium bearing lithologies, but the average grade was 68 ppm lithium. TN22-007 and TN22- 008 lithium results were below the 400-ppm lithium cut-off grade. At site TN22-009, anomalous Siebert Tuff was encountered and returned 56 metres grading 494 ppm lithium.

A northeast oriented fault structure is postulated between TN22-008 and TN22-009 to account for the rapid increase in lithium grade. The fault could act as trapping mechanism for the lithium. Drill holes TN22-006, -012, -13, -019 and TN22-020 were completed in the center of the project area.

All had significant zones above the 400 ppm cut-off grade. TN22-012 returned the highest lithium grade of 1,217 ppm lithium. The higher grades show a northeast trend that needs additional work to understand the distribution of the high-grade lithium values encountered.

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.
