Northbelt Targets: Barney Deformation Corridor

The Barney Deformation Corridor (BDC) target is located approximately 1.5 kilometers northeast of the Crestaurum zone. The BDC structure has been delineated over a strike length of 4.5 kilometers and consists of multiple mineralized shears over greater than 200 meter widths. It is widely recognized to be the northern continuation of the gold mineralized shear system that hosted the past-producing Con (6.1 Moz) and Giant (8.1 Moz) gold mines in Yellowknife, and therefore is a high priority target for discovery.

  • 8km Gold trend – northern extension of Con/Giant
  • High grade gold in wide shear package

Geology:

Barney is hosted in mafic volcanics of the Kam Formation, which was the host to the Con and Giant deposits. Mineralization occurs in two habits:

Broad north trending steeply west dipping deformation zones that contain intervals of intense sericite-carbonate-chlorite schists with abundant quartz veining.

Quartz vein sets located along the contact of the mafic volcanics with a carbonate altered granodioritic porphyry.

The Barney area is also unique in having ultramafic intrusive and extrusive (spinifex textures) rocks proximal to the mineralization.

Sulphides associated with the gold are coarse grained and include pyrite, arseno-pyrite, pyrrhotite, chalcopyrite, galena, sphalerite and molybdenite. The best gold grades occur in near massive to massive sulphide zones with deformed quartz veins. Visible gold is rare.

Porphyry style mineralization containing coarse grained chalcopyrite and molybdenite with gold and silver occurs in the mafic volcanics proximal to the porphyry, and within the porphyry intrusion.

Exploration:

Initial exploration occurred in the summer of 2013, and included mapping and sampling of the Barney structure on surface, and re-logging and sampling of drill cores recovered from campaigns done in 1995-96. TerraX drilling began in 2014 with 10 holes totaling 1923 meters. Intersections included 22.42 m @ 6.35 g/t Au (news release April 25, 2016). This was followed by further drilling in 2015 with 11 holes totaling 2694 meters and intersections up to 14.09 m @ 2.96 g/t Au (news release May 13, 2015). Drilling continued in 2016 with 3 holes totaling 1593 meters targeting the porphyry contact zone and returning 18.10 m @ 1.10 g/t Au, including 5.34 m @ 3.09 g/t Au.

Assay results indicate gold structures mined by Giant just south of TerraX property continue north 4km on BDC target (core from gold zone in NGX hole NB-18 shows identical shear structure, minerals, and chemistry to GKP ore sample, demonstrating the extension of this mineralization style onto TerraX's property).

Future Work:

The Barney Zone's location along the Con-Giant shear and the positive drill results to date has kept this target as one of TerraX's priority areas. TerraX plans to follow-up on its success by further drill testing along the strike and dip extensions of the shear, and to test the mineralization along the porphyry contact zone.

Current focus for Summer 2019

  • Drill Targeting, Historical core Assays
  • Geophysical, Geochemical surveys
