WORK HISTORY

Cantex Mine Development Corp was attracted to the area by the Carlin-type gold discoveries in the Rackla Gold Belt. The company carried out a regional reconnaissance heavy mineral sampling program in 2011. Based on results of the program the company staked NR cl 1 - 651 (YF43001) in Aug/2012 following which they collected 52 heavy mineral samples from creeks draining the claim block.  During the 2013 exploration program the company carried out property-wide soil-talus and rock sampling and further heavy mineral sampling. In 2015, Cantex continued prospecting, rock and infill soil-talus sampling over selected areas of the property, including the Northern Area. In 2016, rock sampling over the occurrence area was carried out.
 
 
GEOLOGY & RESULTS

The North Rackla-Northern Area occurrence lies in a package of Wernecke Supergroup rocks dominated by Paleprotozoic Gillespie Lake dolostone interbedded with lesser black siltstone, shale and laminated mudstone and minor sandstone. Dismembered minor Mesoproterozoic Hart River diorite gabbroic sills and dykes are also mapped in the area (YGS Bedrock Geology, May 2019).
 
The Northern area (also referred to as Area 1) covers a 230 m by 340 m soil-talus anomaly located at the northeast end of the claim block that returned strongly anomalous values for gold, arsenic, antimony, silver, lead and zinc. The area overlies Paleoproterozoic Gillespie Lake Formation rocks consisting of locally stromatolitic dolostone and silty dolostone. Prospecting within the area determined that mineralization was hosted in siliceous gossanous, locally brecciated limestone. Trench, grab and float rock samples have returned values as high as 15.75 g/t gold, 11.0 % lead, 32.5 % zinc and 169 g/t silver. Cantex hopes to test the target in 2017.
