LANGIS-HUDSON BAY
SILVER COBALT PROJECT

Description

The Langis 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. The Langis Mine produced 10.4 Moz Ag at 25 opt and 358,340 lbs of cobalt between 1908 and 1989. The Hudson Bay Mine and property is located 20 km southwest of Langis and historically produced 6.4 Moz Ag at 123 opt and 185,570 lbs Co from 52,032 tons.

Brixton Metals is exploring for silver, cobalt 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. Brixton is actively advancing the Langis Property through drilling, geochemistry, structural mapping and 3D modelling.

Project

  • Two past producing, high-grade silver-cobalt mines in the Cobalt Camp, located 500km from Toronto, Ontario, Canada
  • A brownfields exploration opportunity for high-grade silver-cobalt-nickel
  • LANGIS MINE past production (1908-1989) of 4 Moz Ag at 25 opt and 358,340 lbs of cobalt. (Closed in 1990 due to a silver price drop to $5/oz)
  • HUDSON BAY MINE past production (1905-1953) of 4 Moz Ag at 123 opt and 185,570 lbs cobalt from 52,032 tons
  • Silver-cobalt recoveries ranged from 88% to 98% (assays up to 18% Ag and 16% cobalt)
  • Excellent local infrastructure: year-round road access, power, railway, and mills
  • Brixton signed an Exploration Agreement with the local First Nations in 2016

Why Silver and Cobalt?

  • There is an increased demand for silver and cobalt in the electric vehicle industry, .
    •  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 cobalt is used in a Tesla Model S car
  • Electrical and electronics are the biggest consumer of silver, forecast to use approximately 510 million oz Ag in 2021
  • The photovoltaics (PV) industry is estimated to consume 105 million oz Ag in 2021.
  • Jewelry is one of silver’s biggest demand sectors, using over 170 million oz Ag per year
  • 17% of cobalt consumption is for superalloys, used in space vehicles, aircraft engine parts, and nuclear reactors

COBALT CONSUMPTION

>50% for Li-Ion batteries

(electronics, storage and vehicle use)

140 ktonnes Cobalt produced in 2020

978.1 Moz Silver produced in 2020

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.

Langis Drilling

Regional Silver Camp History

The Cobalt Mining District has produced over 600 Million oz Ag and 28 Million lbs Co (Joyce et al. 2012). One reported mine working 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.

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).
