Brixton Metals discovers kimberlitic body at Langis

2018-08-30 09:44 ET - News Release

Mr. Gary Thompson reports


Brixton Metals Corp. has discovered a kimberlitic body at its Langis project. The company sent a total of 53.6 kilograms collected from the three holes that intersected the kimberlitic rock to SRC Geoanalytical Laboratories Diamond Services (GLDS) in Saskatoon for microdiamond recovery tests. Microdiamond recovery tests returned one diamond from the kimberlite intersected in drill hole LM-18-37.

Chairman and chief executive officer of Brixton, Gary R. Thompson, stated: "We are very intrigued by this discovery. We were targeting cobalt-nickel-silver mineralization in the shallow Archean rocks when we encountered the kimberlitic material. The fact that we recovered a diamond fragment given that the kimberlite sample size was very small is an exciting discovery. The kimberlite in hole 36 to hole 37 is 149 m apart and the distance of the kimberlite from hole 37 to the kimberlite in hole 34 is 515 m. This has piqued our interest as to whether a very large kimberlite pipe or a series of pipes exists."

Three holes encountered kimberlitic breccia directly beneath the overburden (22 m to 40 m vertical depth).

Generally the kimberlitic rock is heavily weathered and brecciated. Additional work to determine the heavy minerals content and petrography is continuing.

The first kimberlite unit was discovered in drill hole LM-18-34. Hole 34 was drilled at 130 degrees azimuth with a dip of 38 degrees. Overburden was encountered to 65 m drill depth of approximately 40 m vertical depth. The kimberlite in hole 34 is a 15 m interval from 65 m drill depth. The kimberlite is very weathered including limestone-rich fragments.

Drill hole LM-18-36 is located 495 m to the northeast from hole 34. Drill hole LM-18-36 was drilled at 120 degrees azimuth and a 38 degrees dip. Overburden was encountered to 36.5 m or about 22 m vertical depth. The syenite-clast-rich kimberlite was encountered over a 14 m interval from 36.5 m.

Hole LM-18-37 was located 149 m northwest from drill hole 36 and 515 m from hole 34. Hole 37 was drilled at 351.5 degrees azimuth and a 38-degree dip. Overburden was encountered to 57 m or about 35 m vertical depth. The kimberlite interval in hole 37 was 44 m in length from 60 m. The kimberlite unit contained limestone fragments and is very weathered.

The company is planning further core and reverse circulation drilling to test for the extent of the kimberlitic body. The company will consult with some of the top diamond exploration experts to assist with the evaluation and assessment of this new discovery.

Vice-president of exploration for Brixton, Sorin Posescu, stated: "This is definitely an interesting time for Brixton and for the Langis project. We are excited to have discovered diamond-bearing kimberlitic rocks and look forward to doing additional work to understand the full extent and the economic potential of this discovery. The Langis project is very well located with excellent infrastructure, year-round road and rail access, power, and low-cost drilling, which ultimately translates to a low cost of exploration."

Quality assurance and quality control

Sealed samples were shipped by the company geologists to SRC Geoanalytical Laboratories Diamond Services (GLDS) in Saskatoon for processing and caustic fusion analysis. SRC Geoanalytical Laboratories Diamond Services is an ISO/IEC 17025:2005 accredited laboratory for laboratory procedures. The GLDS is an SCC accredited laboratory (Standard Council of Canada). The kimberlite samples were analyzed for microdiamond recovery by caustic fusion at over 106 microns.

About the Langis and Hudson Bay silver-cobalt project

Brixton's wholly owned Langis and Hudson Bay past-producing mines are located 500 kilometres north from Toronto, Ont., Canada. The cobalt-silver mineralization occurs as steeply moderately, and in some cases, shallow-dipping veins and as disseminations within any of the three main rock types: Archean volcanics, Coleman Member sediments and Nipissing diabase. The Langis mine produced 10.4 million oz of silver at 25 oz/t Ag and 358,340 pounds of cobalt, and the Hudson Bay mine produced 6.4 million oz of silver at 123 oz/t Ag and 185,570 pounds of cobalt. Historically, the cobalt camp produced 50 million pounds of cobalt as a byproduct of 500 million ounces of silver production.
