DRILLS DISCOVERY HOLE - HIGH-GRADE NICKEL-COPPER-COBALT MINERALIZATION ON EL1 PROPERTY, NW ONTARIO
Crystal Lake Mining Corp.(CLM.V) has released the results from a drill project carried out on its optioned property in Northwestern Ontario.
The EL1 property is one of several optioned by Crystal Lake but is the flagship project that hosts the principal exploration target containing polymetallic nickel-copper-platinum-group-metal (PGM) sulphides hosted within a mafic norite intrusion referred to as the Emo complex, or Dobie intrusion.
Historical drilling from the period beginning in the 1950s to 1972 outlined a mafic intrusive mineralized zone measuring 335 metres in north-south strike direction, 275 metres in width and 305 metres explored depth with a predicted plunge of 30 to 45 degrees north. Stratmat Ltd. (1956) reported a potential resource of 6.4 million tonnes of polymetallic sulphides. Chibtown Copper Corp. (1966) reported indicated reserves of 4.8 million tonnes grading 0.28 per cent copper, 0.24 per cent nickel and 0.05 per cent cobalt. The mineralized body was defined from historical drilling of 220 short drill holes. Both Stratmat and Chibtown Copper were well respected junior miners listed on the Toronto Stock Exchange at the time of disclosure and supervised the drill programs. Key assumptions and methods used to prepare the historical estimates are not known, but both would likely be categorized today as inferred resources. Since those dates, there have been no further or more recent estimates. As the original data are no longer available, the ground would have to be redrilled should Crystal Lake wish to provide its investors with a resource calculation. No work has been carried out by the company to classify the historical estimates as current mineral resources nor is the company treating the historical estimates as a current mineral resource.
While not considered economic at the time, what attracted Crystal Lake is that the disseminated mineralization contains higher-grade parallel north-trending lenses (also referred to as shoots) with historical drilling indicating widths of 4.3 metres to 12.2 metres. One such shoot was estimated to contain 204,000 tonnes grading 0.65 per cent Cu and 0.87 per cent Ni. A total of seven such shoots were identified but not similarly documented as to tonnage or grade. Again, no work has been carried out by the company to classify this historical estimate as current mineral resources nor is the company treating the historical estimate of one such shoot as a current mineral resource. The exploration model developed by Crystal Mining's partner, Emerald Lake Development Corp., is to explore for massive sulphide bodies which may occur below the disseminated low-grade copper-nickel-cobalt mineralization.
In late 2015, the company drilled in total 6,100 feet (1,860 metres) in 10 holes. One drill hole (A-04-15) confirmed that high-grade copper-nickel shoots do exist and are considerably better than previously recorded in the historical drilling. Hole A-04-15 intersected from surface to 63.75 metres (drilled purposely in a downplunge direction to confirm continuity) a weighted average of 1.05 per cent nickel and 2.18 per cent copper. Note that the intersection of mineralization in hole A-04-15 does not represent the true width of the zone and that, as the hole was purposely downplunge, the true width of the mineralized zone is materially narrower than the drill hole intersection.
Of significance, the bottom 9.8-metre section averaged 1.92 per cent nickel, 0.17 per cent copper and 0.132 per cent cobalt.
What is intriguing, and represents the exploration potential of the EL1 deposit, is the depth extent of the mineralization and whether these shoots lead to a massive sulphide zone at depth at better grades. Further deeper drilling would support this model.
The company is also investigating further into value and recovery of secondary metals such as PGMs, cobalt, gold and silver.
Management of Crystal Lake Mining stated: "We thank Emerald Lake Development and its exploration team led by Frank Puskas (honours BSc geology/chemistry, MSc geology); his modelling of the EL1 property, core logging, evaluation and data interpretation in the stage 1 program was instrumental. An independent review and interpretation of current exploration data on the EL1 project leads us to believe that the documented mafic intrusion exhibits the potential for significantly higher-grade copper-nickel-bearing mineralization at depth. Our work in this area appears to be justified and well focused. Our encouraging results indicate that we are on the right path, and we feel that there exists considerable potential for success."
