Canadian Silver Hunter Inc. (the "Company") is pleased to release final results of recent sampling at the Keeley Frontier silver project in South Lorrain Township, Ontario. The Company completed a power-stripping and channel sampling program near Gibson Lake on the main Keeley Frontier claim block in November of 2012. As well, one pit was dug by excavator to a depth of 2 metres in a tailings area, with five grab samples taken at various depths in the tailings profile.
Highlights
- Channel line 7 returned composite silver values of 69.3 g/t Ag over the full length of 2.9 metres, including 86.8 g/t Ag over 2.25 metres.
- These samples also include base metal values of 0.91% Pb, 0.65% Zn, 0.28% Cu over 2.25 metres.
- One sample returned a value of 174 g/t Ag and 1.46% Pb over 0.95 metres.
- Channel line 8 returned a composite silver value of 28.0 g/t Ag over 2.05 metres, with 0.58% Pb, and 0.69% Zn. The composite included 70 g/t Ag 1.31% Pb, 1.64% Zn and 0.42% Cu over 0.6 metres.
- Channel line 2 returned a composite silver value of 70.4 g/t Ag over 1.85 metres, including 190 g/t Ag over 0.6 metres.
- Five (5) grab samples of tailings material (sand, silt and clay) exposed at various depths in one location by an excavator at depths ranging from surface to 1.8 metres depth returned silver values of 404 g/t Ag, 191 g/t Ag, 175 g/t Ag, 124 g/tonne and 74.8 g/t Ag.
- The tailings grab samples also assayed up to 0.053% bismuth, 0.33% cobalt, and 0.09% nickel.
A total of 50.45 metres of channel cuts were completed and assayed for silver and trace elements. The average length weighted composite for all 77 channel samples taken is 11.33 g/t Ag, 0.12% Pb, 0.14% Zn and 0.12% Cu. Silver values ranged from 0.4 g/t to 190 g/t, with only seven samples assaying below 1.0 g/t Ag. A similar widespread dispersion of Pb, Zn and Cu values was also noted, with a high correlation to Ag values.
The stripped area consists of one rock type; pillowed mafic volcanics, cut by numerous brittle steeply dipping fractures and faults trending mainly between 310 and 330 degrees. Disseminated pyrite, chalcopyrite, galena, sphalerite, arsenides, native silver and bismuth were visible within and adjacent to many of the fractures. Calcite, and reddish dolomitized volcanics were locally present.
The Gibson Lake structural trend was located by surface prospecting of IP anomalies during the summer of 2012. Historic trenching was exposed using an excavator and high pressure water for approximately 40 metres along strike. Additional caved trenches can be observed along the trend. The width of the mineralized trend is exposed for 10 to 15 metres.
There are no records of previous exploration results in the Gibson Lake area. Silver and cobalt production are known to have occurred 300 metres to the east from the Woods and Watson veins. It is important to note that the current surface stripping is well outside (above by approximately 100 metres) the historic "productive zone" with which the Keeley Frontier high grade silver zones are associated. The "productive zone" follows the shallow dipping Nipissing sill/volcanic rock contact, generally 100 metres above and 50 metres below the sill contact, where most of the high grade silver and cobalt has been found. The top of the "productive zone" could be reached with a 150 metre long drill hole beneath the Gibson stripping.
It is also of interest to note that historic exploration and production in the South Lorrain silver camp focused on underground drifting along narrow high grade structures and there was generally no exploration for wider, lower grade mineralized zones using geophysics, surface drilling or power-stripping. Strong chargeability anomalies from earlier IP surveying completed by the Company suggest the presence of disseminated sulphide/arsenide targets along a northwest trending anomaly 100 metres wide by at least 400 metres long stretching northwest from the Gibson Lake area stripping.
Follow-up work on the Gibson targets will include additional geophysics and power-stripping, with shallow drilling based on additional channel sampling results. Additional power-stripping is also required proximal to hole CSH12-03 (168.22 g/t Ag over 4.2 metres within a zone grading 72.47 g/t Ag over 11.3 metres, see June 19, 2012 press release). Weather conditions this fall did not allow for sufficient power-washing of the site and no channel sampling could be completed. This area is 750 metres south of the Gibson Lake stripping and remains a high priority for surface sampling and diamond drilling.
Sampling along the edge of Little Beaver Lake was done in one location to examine the depth of tailings and distribution of silver and other metals in the tailings profile. Five (5) samples were assayed at Agat Labs and returned silver values between 74.8 g/tonne (2.18 ounces per ton) and 404 g/tonne (11.78 ounces per ton). These silver levels are encouraging and systematic sampling of tailings is being considered as part of the next exploration program.
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. Samples were 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, power-washing 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 to the requirements of CAN-P-4E (ISO/IEC 17025:2005) and CAN-P-1579 by the Standards Council of Canada. AGAT Laboratories provided pickup of the channel and tailings samples from the Company's 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 the Company's personnel every 25 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 multi element 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.
