Blackrock Silver Corp. announced that Tearlach Resources Ltd. ("Tearlach"), which holds an option to acquire, in two stages, up to a 70% interest in the lithium minerals in certain unpatented mining claims forming a portion of the Company's Tonopah North lithium project (" Gabriel"), has reported initial drill results from the first five of eleven completed drillholes from Tearlach's Phase-1 core drilling program at Gabriel. All drillholes reported significant lithium mineralization, including the highest-grade intercept at Gabriel to date of 1,460 parts per million (ppm) Lithium (Li) over 2.7 metres.

Tearlach's drilling has confirmed Blackrock's original Tonopah North lithium discovery with core drillholes delivering grades that range from 40-85% higher than the corresponding original reverse circulation (RC) intercepts drilled by Blackrock. These results substantially increase the grade and expand the mineralized zone at the project. Gabriel is situated in West Central Nevada along the emerging Tonopah lithium belt, abutting American Lithium Corp.'s TLC deposit.

Initial results from Tearlach's phase-1 core drill program demonstrate two key things. First, Tearlach confirmed Blackrock's lithium discovery with two core holes twinning Blackrock's RC drillholes. Second, Tearlach's program completed significant step-out drillholes targeting prospective locations throughout the property.

Confirmation drilling was successful in establishing the discovery with drill core assays returning grades significantly higher than previously reported. Step-out drilling expanded the footprint of mineralization across a general area of 1.5 x 2.75 kilometres (km) and delivered the highest-grade intercepts at the project. In addition to its gold and silver project portfolio, the Company is credited with a lithium discovery, the Tonopah North project, which is under option to a major lithium exploration group.
