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 2016 the company geologically mapped selected areas, prospected and continued infill soil-talus and rock sampling. 
 
GEOLOGY & RESULTS

The North Rackla-Central Silver 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 of the Quartet Group. Dismembered minor Mesoproterozoic Hart River diorite gabbroic sills and dykes are also mapped in the area (YGS Bedrock Geology, May 2019)
 
A prospecting program in 2013 lead to the discovery of the 200 X 70 m Central Silver area, which returned significant silver values as high as 9810 g/t . This sample (KAR 3208) also returned 12.4% Cu, 14.35% Pb and 1.53% Zn.
