The Keeley & Frontier Mines, Silver Centre, Cobalt, ON
Canadian Silver Hunter’s wholly owned Keeley and Frontier Mines are located in Silver Centre, just south of Cobalt, Ontario. The Keeley-Frontier Mine produced a total of 19.2 million ounces of silver and over 3.3 million pounds of cobalt at a recovered grade of 58 ounces of silver per ton, and 0.5% cobalt (3.3 pounds/ton) respectively.
Historically the South Lorrain Township (Silver Centre) had produced a total of 23,338,906 oz of silver with 82% of this coming from the Keeley and Frontier Mines, and over 50% from the Keeley Mine itself
The Keeley-Frontier mine also had the best cobalt-to-silver ratio of all the major historic mines in the Cobalt camp, suggesting that there may be other silver-cobalt-rich areas that were not targeted or exploited during mining.
The Keeley Frontier mine has extensive underground workings, including ten shafts and several winzes extending to a depth from surface of 1525 feet (465 metres).
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.
The Company intends to gain a greater appreciation for the silver and cobalt zonation within the mine and close to surface as well as new prospective mineralization and of the potential for disseminated mineralization, which could be amenable for bulk mining and potential open pit development.
The Keeley & Frontier Mines Selected Results
Diamond drill hole CSH12-03 returned significant silver values between 111.0 and 122.3 metres downhole, including the following screen metallic assays:
1517.0g/tonne over 0.3 metres
479g/tonne over 0.4 metres
91g/tonne over 0.3 metres
The entire interval starting at 111.0 metres returned a composite silver value of 72.47 g/t Ag over 11.3 metres, including 168.22 g/t over 4.2 metres. This zone appears to be related to a new silver-bearing structure as well, anomalous silver, cobalt and copper values occur throughout the upper portion of CSH12-03 associated with faulting, lamprophyre dykes and syenite bodies.
· CSH12-05 returned a composite silver value from the Beaver Lake Fault of 398.42 g/tonne over 1.9 metres.
Power-stripping and channel sampling near Gibson Lake on the main Keeley Frontier claim block returned significant silver values across the sampling area;
-
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.
A total 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.
Sampling along the edge of Little Beaver Lake, located just south of the Keeley mine main shaft was completed in one location to examine the depth of tailings and distribution of silver and other metals in the tailings profile. 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.(PR January 18, 2013).
The Company has commenced assimilating all recent and historic production, drilling and development data on its Silver Centre property, with plans seeking to maximize the mineral potential of the property. Follow-up drilling is planned, and additional areas for surface sampling and multi-element assaying are being evaluated by ongoing geological mapping. Follow-up work being considered on the Gibson Lake and Keeley South targets include additional power stripping, channel sampling and geophysics followed by a shallow, tightly spaced drill program, based on existing and new data. This work will also aid in correlating numerous collapsed trenches on surface with silver-copper-cobalt-bismuth-nickel bearing structures outlined by more recent drilling.
