Testing Highly Conductive Anomalies In Manitoba
Callinex Mines Inc. (TSXV: CNX) (OTC: CLLXF) has commenced its 2020 northern summer drilling campaign at its Pine Bay Project located 16km away from processing facilities in the Flin Flon Mining District of Manitoba.
The Campaign will complete up to 1,500m of drilling at the Project to test two newly identified Borehole Pulse Electromagnetic anomalies (BPEM). These anomalies are interpreted to be off-hole from sulphide stringers that include copper, zinc, gold and silver mineralisation and within the known Centennial mine horizon, which hosts the Sourdough VMS deposit and the past producing Centennial Mine, located four and seven kilometres respectively to the south of the untested BPEM anomalies.
A BPEM survey completed in drill hole PBM-033 identified Anomaly A, a highly conductive 260m by 600m anomaly possessing a conductivity thickness (CT) of 450 siemens.
In addition, a subsequent BPEM survey completed on hole PBM-037 identified Anomaly B which is modeled to be 200m by 500m with a CT of 350 siemens.
Callinex President and CEO, Max Porterfield, said any EM conductor with a strike extent over 100m and a CT of over 100 siemens within a known mine horizon is regarded as a highly prospective target within the Flin Flon Mining District.
Anomalies A and B are interpreted to occur off-hole and within the same plane as the disseminated to semi-massive sulphide stringers intersected by PBM-037. Drill hole PBM-037 intersected chlorite-altered rhyodacite flow-hosted, coarse red-brown sphalerite and chalcopyrite-bearing sulphide stringers between 945.8m and 946.8m in a setting typical of a footwall alteration zone (See Core Photo 1). Red-brown sphalerite often is an indication of higher temperatures and close proximity to VMS discharge systems.
Callinex’s Pine Bay Project encompasses the majority of the Baker Patton Complex (BPC), the largest exposed felsic (rhyolitic) volcanic accumulation in the Flin Flon portion of the Flin Flon-Snow Lake Greenstone Belt.
This is especially important since the majority of the VMS deposits occurring within the Flin Flon Belt of Saskatchewan and Manitoba are almost always hosted by rhyolitic flows and volcaniclastic rocks within predominantly mafic terranes.
Of additional importance is that these felsic (rhyolitic) rocks only account for a small portion of the total volcanic pile (5-10%). Of particular exploration interest to Callinex’s Pine Bay Project, is the very large exposure of intensely altered (chloritic, sericitic and silicic alteration) felsic rocks that have collectively been called the Baker Patton Alteration Zone, encompassing an area with a minimum of a 700m by 1000m footprint. Mr Porterfield said a very large footwall alteration system such as this would normally be expected to be accompanied by a large VMS system and has consequently been the target of many exploration companies preceding Callinex.
