LANGIS MINE PROJECT

The Langis Mine (past producer of high-grade silver) Project is located near Cobalt in eastern Ontario, 15 km north of Temiskaming Shores and 500 km north of Toronto. Highway 65 runs through the property and many established secondary roads provide year-round access. Power, railways, mills, a permitted refinery, and assay lab are located at or near the site.

Brixton Metals is exploring for cobalt, silver, and other semi-precious and precious metals on blocks of contiguous mining patents and mining claims covering parts of two townships in the historic Cobalt Mining Camp: Casey and Harris townships

The Langis Project represents a unique opportunity in a silver district that is underexplored using modern techniques. New discovery potential is high, and a strong possibility exists to generate mineral resources from extensions to historical workings and new exploration.

Why Silver and Cobalt?

There is an increased demand for silver and cobalt in the electric vehicleindustry, .
- 60 million oz of Ag are projected to be used by the automotive industry in 2021. Each battery electric vehicle uses approximately 25-50g of silver.
- Approximately 4.5kg of cobaltis used in a Tesla Model S car
Electrical and electronicsare the biggest consumer of silver, forecast to use approximately 510 million oz Agin 2021
The photovoltaics (PV) industry is estimated to consume 105 million oz Agin 2021.
Jewelry is one of silver’s biggest demand sectors, using over 170 million oz Agper year
17% of cobalt consumption is for superalloys, used in space vehicles, aircraft engine parts, and nuclear reactors

Regional Geology

The Cobalt Mining District has produced over 600 Million oz Silver and 28 Million lbs Cobalt*
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.

Regional Silver Camp History

The camp has historically produced over 420 Moz of silver. One reported mine workings from the Cobalt Camp reached 255,146 g/t Ag (or 9,000 oz/t Ag) over 0.36 metres. This single stope at the 30 m level on this vein produced 4.5 Moz Ag.

The “Camp History” photo shows some headframes established within the Cobalt mining camp (photo source: Cobalt Mining Museum). While today most of the mine sites have been reclaimed or are under ongoing reclamation.

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. They found silver-bearing float at the south end of Cobalt Lake. The first assay results showed bismuth but no silver. McKinley subsequently sent the ore for assay to McGill University, and was informed by Dr. Milton Hersey of Montreal that the ore contained 4,000 ounces of silver per ton. Dr. Willet G. Miller, Ontario’s first provincial geologist, visited the area in November 1903 and found that four veins had been located, three very rich in silver. In addition, Tom Hebert had staked the property that later became the Nipissing Mine. Dr. Miller reported the news through an article in the Mining Journal of New York and through an Ontario Bureau of Mines publication. The final discovery in 1903 was made by Neil King who staked the property on which the O’Brien mine was to rise in 1906 and to continue production without a break until 1966 (Zoldy, 2006).
