The 2020-2021 fall/winter drill program results identified very encouraging broad zones of silver, cobalt, and nickel mineralization. Over the past year, the company has spent significant time remodeling all results and has identified three domains of interest.

“The domains include cobalt-nickel associated with the Archean basement rock, gold within the Algoman Syenite, and native silver+-cobalt found within most lithologies. The results from the IP survey, mapping, and geochemical sampling will allow us to refine the drill targets for the 2022 fall drill program,” Thompson added.
Due to an absence of outcrop exposure and a substantial sequence of glaciolacustrine Pleistocene overburden that underlies most of the land, notably to the east, there has been minimal surface mapping and sampling on the Langis property in the past. Once first results from the Alpha IP survey are obtained, a small-scale reconnaissance campaign to map exposed outcrops and gather rock samples is proposed for early spring.
Polymetallic calcite–quartz vein systems carrying precious metals are found throughout the Cobalt Camp, particularly on the Langis property. Along with Nipissing diabase contacts and the unconformity between Archean Keewatin basement rocks and the overlaying Huronian sediments, ore-bearing veins have been discovered.
Archean basement architecture and pre-Huronian erosion valleys appear to be predominantly responsible for ore-grade mineralization zones, especially where strata of Archean pillow-interflow sediments occur and steeply dipping faults meet.
From previous work and more current drilling by Brixton, three separate mineralization trends have been found at Langis:
- Within the Huronian deposits, silver mineralization is found primarily in vertical, dilatant zones and shear veins.
- Broad envelopes of high-grade cobalt mineralization are found mostly within the Keewatin Basalt, frequently at or below the contact of Huronian sediments.
- A large nickel anomaly probably exists beneath the cobalt mineralization and around the Huronian-Archean unconformity.
Prior exploration and mining at Langis have primarily concentrated on silver production; nevertheless, the area has the capacity for considerable cobalt-nickel deposits.
Furthermore, the property’s gold potential remains largely untapped, especially inside the Archean Algoman syenite to the northwest of the mine property, which itself is part of the Abitibi Greenstone belt’s regionally promising intrusive complex, which is noted for its economic gold endowment.
The potential for multiple generations of mineralization on the Langis Project is very encouraging. In addition to the geophysical survey, mapping and surface sampling, the Company plans to conduct re-assaying of select high nickel bearing material for platinum group metals which has not been done previously. We are looking forward to testing these new gold, cobalt-nickel and silver rich domains through drilling.
