Canadian Silver Hunter Inc. recently completed powerstripping and channel sampling at the Keeley-Frontier silver cobalt project in South Lorrain township, Ontario.
Historic 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 favourable results (See Canadian Silver Hunter press release January 18, 2013). Silver and cobalt production are known to have occurred 300 metres to the east from the Woods and Watson veins.
Another area along the #1 Fault structure, proximal to the Frontier #1 Shaft, was powerstripped in 2013. This area is located 440 metres east of the Gibson stripping. No channel sampling was done along the powerstripped areas in 2013 due to depth of overburden and flooding of the trenches. In 2014 the area was revisited, with additional powerstripping, mapping and channel sampling. Results from this work indicate that the #1 Fault structure in this area consists of a wide (20 metres) zone of fractured, epidotized and silicified pillowed volcanics, 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 metres.
CSH believes that the information gained by exposing outcrop in areas proximal to historic silver-bearing structures and performing geochemical and structural analysis will ultimately locate new zones of silver-cobalt mineralization. CSH will also continue to compile historic data in order to put more recent (2012-2014) 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.
Project Logistics and QA/QC
All analyses reported in this release are from assay certificates which passed both Canadian Silver Hunter, and AGAT Laboratories QA/QC procedures.
Channel samples were cut with a gas powered saw using a diamond blade, similar to a core cutting saw and sent for aqua regia digestion and multi-element (including Ag, Co, Ni, Bi, Sb) analysis (ICP-OES finish) at AGAT Laboratories Ltd. in Mississauga, Ontario. The excavating, powerwashing and channel cutting program was carried out under contract by Laframboise Drilling Inc. of Earlton Ontario, managed and supervised by David R. Jamieson, P.Geo and Dean R. Cutting, P.Geo.
AGAT is a fully accredited laboratory and conforms with the requirements of CAN-P-4E (ISO/IEC 17025:2005) and CAN-P-1579 by the Standards Council of Canada. AGAT Laboratories provides delivery of the channel and tailings samples from the Canadian Silver Hunter core shack in North Cobalt, to the preparation lab in Sudbury, Ontario. Analysis is performed at AGAT facilities in Mississauga, Ontario. QA/QC programs include the use of standard and blank samples inserted into the assay stream, including the tailings samples, by Canadian Silver Hunter personnel every 20 samples in addition to the lab's internal QA/QC programs. Samples assaying greater than 100 g/t Ag are fire assayed with a gravimetric finish. QA/QC results indicate that the AGAT aqua regia digestion and multielement analytical procedures used on this program are reliable. Screen metallic assaying may be required to more accurately quantify silver values in higher grade portions of the mineralized zones due to the presence of coarse silver.
