Langis-Hudson Bay
A brownfield exploration and development opportunity for high-grade silver-cobalt-nickel with excellent local infrastructure, including year-round road access, power, railways and mills. Langis is located within the Timiskaming First Nation traditional territory.
Additionally, a Tesla Model S car alone requires around 4.5 kilograms of cobalt. Silver finds its largest consumption in the electrical and electronics sector, which is expected to use approximately 510 million ounces of silver in 2021. Furthermore, the photovoltaics (PV) industry estimates a consumption of 105 million ounces of silver in the same year. Silver’s demand extends to the jewelry sector as well, with an annual usage of over 170 million ounces of silver. In the case of cobalt, 17% of its consumption is allocated to superalloys, utilized in space vehicles, aircraft engine parts, and nuclear reactors.
Historically, the Langis Mine produced over 10.4 Moz Ag with a recovered grade of approximately 25 oz/t from shallow depths, and 358,340 lbs of cobalt and the Hudson Bay Mine produced 6.4 Moz Ag at 123 oz/t, and 185,570 lbs of cobalt from 58,000 tons.
Currently, both the Langis and Hudson Bay Projects do not have any mineral resources or mineral reserves. The Langis Mine operated from 1908 to 1989 and was subsequently closed in 1990 due to a significant drop in silver prices to $5 per ounce (oz) of silver (Ag). The Langis Mine boasted impressive silver-cobalt recoveries, ranging from 88% to 98%, with assays showing values of up to 18% silver (Ag) and 16% cobalt. The Langis Mine features over 10 kilometers of underground workings, but these historic workings are currently flooded.
Regional Silver Camp History
Silver was discovered at Cobalt in 1903 during the construction of the Timiskaming and Northern Ontario Railway from North Bay to develop the agricultural land in the New Liskeard area. Fred LaRose, a blacksmith employed in the construction of the railway, is credited with the first discovery, but the first application for claims, filed on August 13, 1903, was made by J.H. McKinley and E.F. Darragh, subcontractors who supplied ties for the railroad.

Regional
The steeply-dipping, Archean mafic volcanic rocks are overlain unconformably by the flat-lying Proterozoic Cobalt Group sediments, cut by the Nipissing diabase sills. These three units are host to the Ag-Co-Ni mineralizing system.
Langis
Archean Keewatin volcanics: These rocks comprise both metavolcanics and metasediments. The volcanics are most commonly intermediate to mafic pillowed basalt and massive flows. Between flows, deep-water cherty sediments and pyroclastic rocks were deposited. These interflow sediments are commonly rich in pyrite, pyrrhotite, chalcopyrite, galena, and sphalerite. Throughout the area, the volcanics are intruded by various mafic and ultra-mafic dykes.
Algoman intrusive: A large hornblende syenite pluton intruding the mine property has potential for gold mineralization but is underexplored to date.
Proterozoic Huronian Supergroup: Huronian rocks comprise the majority of exposed outcrop on the Langis property and consist of gently-dipping, unaltered clastic, glacially-derived sediments unconformably overlying the older Keewatin volcanic and intrusive rocks (Lowes, 1963). These sediments form the Coleman Member of the Gowganda Formation and consist of para- and ortho-conglomerates, pebbly sandstone and greywacke, and thinly-bedded argillites.
Early Proterozoic (Keewenawan): Rocks of this age are represented by the Nipissing diabase sill, a prominent and important rock type in the Cobalt Basin. The diabase intrudes in the form of extensive sheets as well as less prominent dykes and plugs.
Geophysics
The Langis Project is predominantly covered by overburden, particularly in the eastern region, which suggests the possibility of additional silver zones being concealed. By integrating property-scale geophysics with the existing drill data, geological and structural interpretations can be enhanced, aiding in further understanding the project’s potential.
Hudson Bay
The Hudson Bay Mine had a historical production of 6.4 million ounces (Moz) of silver (Ag) at an average grade of 123 ounces per ton (opt) and 185,570 pounds of cobalt (Co) from 52,032 tons of ore. The mine operated between 1905 and 1953. The property hosts silver-cobalt-nickel (Ag-Co-Ni) mineralization within Archean and Precambrian rocks.
Mineralization at the Langis project consists of high-grade silver-cobalt assemblages, and moderate to high-grade base-metal sulphide assemblages.
A base metal sulphide assemblage makes up a significant proportion of the mineralization intersected at Langis, and consists of pyrite, sphalerite, chalcopyrite, and rarely galena, pyrrhotite, and marcasite.
Sulphides
Medium to fine-grained sulphides are hosted in carbonate ± chlorite ± hematite ± quartz veins, with ± silver ± cobalt mineralization.
High-grade
Mineralization is characterized by cobaltite, smaltite, and other silver arsenides in veins and veinlets.
Interlocking
Cobaltite Is generally coarse-grained and intergrown with finer silver and nickeline, while native silver occurs as flaky fracture coatings and hairline stingers near other mineralization.
Alteration mineral assemblages and styles present suggests that a large-scale, albeit weak, hydrothermal system (or systems) was in effect: silica, chlorite, and carbonate are the most observed alteration minerals throughout the area drilled. Chlorite ± silica ± carbonate preferentially alter drilled mafic volcanic rocks. Chlorite ± iron oxide (hematite) preferentially alters the conglomerate.
Fault and structurally related alteration effects are also present: rocks altered moderately to intensely by clay minerals, sericite, and carbonate are found spatially associated with broken, rubbly, and sometimes gougey core.
Based on the observations made throughout the multiple drilling programs, alteration minerals observed, which directly correlate with high-grade mineralization, are restricted to carbonate, calcite and chlorite, as well as base-metal sulphide minerals. These are also the known alteration assemblages and characteristics defining the Cobalt Mining District.

There is an increased demand for silver and cobalt in the electric vehicle industry, with the automotive sector projected to use 60 million ounces of silver in 2021. Each battery electric vehicle typically utilizes approximately 25-50 grams of silver.
Additionally, a Tesla Model S car alone requires around 4.5 kilograms of cobalt. Silver finds its largest consumption in the electrical and electronics sector, which is expected to use approximately 510 million ounces of silver in 2021. Furthermore, the photovoltaics (PV) industry estimates a consumption of 105 million ounces of silver in the same year. Silver’s demand extends to the jewelry sector as well, with an annual usage of over 170 million ounces of silver. In the case of cobalt, 17% of its consumption is allocated to superalloys, utilized in space vehicles, aircraft engine parts, and nuclear reactors.
The Langis Project offers a brownfield exploration opportunity for high-grade silver, cobalt, and nickel. The project has demonstrated promising silver-cobalt recoveries, ranging from 88% to 98%, with assays showing values of up to 18% silver and 16% cobalt.
In 2016, Brixton signed an Exploration Agreement with the local First Nations. The Langis Project is situated within the traditional territory of the Timiskaming First Nation. Highway 65 runs through the property and many established secondary roads provide year-round access and excellent infrastructure. Power, railways, mills and a permitted refinery are located near the site.
