​TSX-GTT new high grade gold discovery which TSX-GTT announced is open to extension to west and east.
TSX-GTT discovers gold in 10 out of 10 drill holes as of July 25, 2017, in area of northern cordillera rock belt that hosts gold, copper-gold deposits from CHILE TO ALASKA.
First time in British Columbia section of northern Cordillera that a potential gold deposit will be found in area of huge copper-gold deposits, 30km to the Southeast is the RED CHRIS copper gold mine of Imperial Metals, to the northwest is the several copper-gold deposits. 
the first time gold deposit may be found around the copper gold deposits in B.C. as the gold deposits are known to occur around the copper-gold deposits in the USA, CHILE.
Durango with ground adjacent to TSX-GTT on the west and east, then also surrounded by TSX-CXO to the south, and north, east and south on the east side of TSX-GTT.
TSX-GTT announced in news the high grade gold discovery is open to the west and east.

From US geological survey porphyry copper deposits open file  clearly states these types of deposits can occur in area, Sillitoe in public presentations has also commented on clusters of copper-gold deposits with gold deposits.

"Polymetallic replacement deposits occur in carbonate-bearing units peripheral to porphyry-style mineralization. At Bingham, Utah (Babcock and others, 1995), and Bisbee, Arizona (Bryant and Metz, 1966), polymetallic replacement deposits
surround the intrusive complexes with offshoots appearing to radiate outward from the stocks. Vein deposits occur peripheral to many porphyry copper deposits (for example, Bingham, Utah), as well as crosscutting porphyry-style mineralization (for example, Valea Morii, Romania)"    OPEN FILE USGS 2008-1321

Imperial Metals discovered the RED CHRIS mine in 2012, with huge copper intercepts from 500 meters to 1000 kilometers lengths. Mine is in production, and is 30km southwest of the TSX-GTT strike.​
