Discovers New Copper-Gold-Silver Potential In BC
Benchmark Metals Inc. (TSXV: BNCH) (OTCQX: BNCHF) has confirmed it has completed more than 41,000m of drilling with six drill rigs currently operating at its ongoing resource expansion programme and advancement of new regional targets on its flagship Lawyers Gold-Silver Project in British Columbia, Canada.
The company is also nearing completion of a comprehensive geological reconnaissance programme consisting of rock and soil sampling, mapping, and geophysics; resulting in a significant expansion to its robust database that will provide further opportunities to outline new potential on highly prospective zones that remain open.
As a result of the Regional Exploration Programme the company has generated the new ‘Black Lake’ copper gold-silver zone located within the southern portion of the project. The systematic exploration work has identified the Black Lake target as being highly prospective for copper-gold-silver mineralising systems.
Results from the 2021 exploration programme at Black Lake has identified east-northeast and northwest mineralised corridors extending over 500 metres in strike-length, with rock grab samples assaying up to 1.25 grams per tonne (g/t) Au, 137 g/t Ag, and 829 parts per million (ppm) Cu.
CEO, John Williamson, said these results verify the presence of copper-gold systems within the same regional host rocks known to host copper-gold porphyries such as the Kemess Mine located ~45 km to the southeast.
“The discovery of new copper-gold-silver mineralization on the project demonstrates the effectiveness of our methodology to consistently identify new and highly prospective zones for targeted systematic exploration,” Mr Williamson said.
“The 2021 regional exploration programme has been very successful in outlining the grassroots potential of these large new target areas and verifies the robust nature of a variety of mineralising systems that exist across the +20 kilometre Lawyers Trend.”
Black Lake Exploration Target
Initial exploration at the Black Lake target, located ~six km to the south of the Cliff Creek resource zone, has identified mineralised corridors trending to the northwest and northeast with rock grab and soil samples indicating gold, silver, and copper mineralisation.
The Black Lake zone provides new grassroots opportunities to explore for copper-gold mineralising systems within the Late Triassic Takla Group volcanic rocks and Black Lake intrusives that are located within the southern portion of the Lawyers project; these units are known to host the Kemess Copper-Gold Mine ~45 kilometres along-trend to the southeast.
Within the Black Lake target zone are the highly prospective Black Lake Alteration Corridor, R3 Stockwork, and Fern Gully zones which remain open.
Airborne VTEM geophysical and radiometric survey
An airborne VTEM geophysical and radiometric survey is currently underway spanning the southern half of the Lawyers Gold-Silver Project, which includes the Black Lake target.
This survey will allow for improved identification and targeting of electromagnetic (EM) and potassic anomalies associated with porphyry and epithermal mineralisation. Targeting EM and potassic anomalies has been proven effective within the northern portion of the project with a number of new gold occurrences identified at surface as well as coincident soil anomalies.
