Keeley-Frontier Silver Cobalt Project Update
TORONTO, ON - Canadian Silver Hunter Inc. completed power stripping and channel sampling at the Keeley-Frontier silver cobalt project in South Lorrain township, Ontario.
Past production at Keeley-Frontier totaled approximately 20 million ounces of silver and 3 million pounds of cobalt from several key fault/vein structures. Mining ceased in 1967 due to low silver prices, despite the discovery of new productive structures. Many more fault/vein structures on the property were outlined but not fully explored. CSH has been evaluating the historic exploration and production records in conjunction with surface exploration to generate high priority silver/cobalt targets.
One of the main fault structures on the property (#1 Fault) is located in a past-productive area; however the fault did not receive extensive exploration. This may have been due to the fact that the #1 Fault structure is oriented east-west, while production in the area came mainly from north-south oriented fault/vein structures.
Much of the #1 Fault structure is buried beneath mine muck stockpiles and tailings. One area on the west side of Gibson Lake was stripped and sampled in 2012 with favorable results. Silver and cobalt production are known to have occurred 300 meters to the east from the Woods and Watson veins.
Another area along the #1 Fault structure, proximal to the Frontier #1 Shaft, was power stripped in 2013. This area is located 440 meters east of the Gibson stripping. No channel sampling was done along the power stripped areas in 2013 due to depth of overburden and flooding of the trenches. In 2014 the area was revisited, with additional power stripping, mapping and channel sampling. Results from this work indicate that the #1 Fault structure in this area consists of a wide (20 meters) zone of fractured, epidotized and silicified pillowed volcanic, cut by syenitic and micaceous dykes.
These Frontier #1 Shaft area channel samples returned anomalous silver, arsenic, cobalt, copper and nickel (up to 20.7 g/t Ag, 0.16% As, 0.16% Cu, 0.026% Co, 0.07% Ni). It is important to note that no discrete veins were sampled and that the higher metal values are associated with pyrrhotite-pyrite-chalcopyrite veinlets within patchy epidote-silica altered volcanics. The mineralization and assay results are similar to the Gibson lake area, although the Gibson Lake area returned locally higher silver, zinc and lead values including 86.6 g/t Ag, 0.28% Cu, 0.65%Zn and 0.91% Pb over 2.25 meters.
CSH will continue to compile historic data in order to put more recent surface and drill core sampling into perspective. Detailed EM and IP geophysical techniques will be tested as a guide to drilling, which will focus on very conductive high grade silver targets as well as more disseminated silver-cobalt-nickel targets.
