LANGIS-HUDSON BAY
SILVER COBALT PROJECT

Description

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.

Project

  • Two past producing, high-grade silver-cobalt mines in the Cobalt Camp, located 500km from
    Toronto, Ontario, Canada
  • A brownfields exploration and development opportunity for high-grade silver-cobalt and +- copper, +-nickel, +-gold
  • LANGIS MINE past production (1908-1989) of 10.4 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 6.4 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
  • Currently drilling towards maiden NI-43 101 resource

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.

Brixton's Drilling Highlights

  • 2018, drilling hit new high grade silver-cobalt mineralization:
    • LM18-42 intersected 6.00m of 4,719.33 g/t silver and 0.33 percent cobalt
    • LM18-45 intersected 3.00m of 1.23 percent cobalt, 43.97 g/t silver
  • 2020, LM-20-133 cut 2m of 5,847 g/t Ag from 16.6m, including 1.2m of 11,663 g/t (375 oz/t) Ag, 0.71% Co 
    • including 9m of 272 g/t Ag from 23.6m including 1m of 1,500 g/t Ag, 0.26% Co

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).
