New drill results from the Sheraton-Timmins project of Cross Lake Minerals (CRN-V) in northeastern Ontario’s Sheraton Twp., indicate a wide package of mineralized zones along a strike length of about 300 metres.
Three of the newest holes intersected the prospect’s copper zone, a funnel-shaped body of felsic fragmental rocks with strong chloritic alteration. The copper mineralization is in layers, stringers and disseminations generally grading 1-2% copper, with silver credits.
The longest intersection, in hole CLS97-29, graded 1.07% copper and 6.3 grams silver per tonne over a core length of 47.5 metres. Nearby, CLS 97-25 intersected two separate zones, each 3 metres long, one grading 2.21% copper and 8.1 grams silver, and the other grading 1.95% copper and 7.8 grams silver.
Along strike to the southwest, hole CLS 97-31 cut a 19-metre intersection grading 1.38% copper and 11.2 grams silver per tonne; more assays from further down the hole should be available shortly.
Results from other drill holes in the copper zone showed similar grades, including a 22.5-metre intersection grading 1.41% copper and 7.5 grams silver, and a 3-metre intersection running 1.31% copper and 28.1 grams silver per tonne. The picture of the copper zone that is now appearing from these drill results shows a body of irregular width with most of its wider intersections down-plunge to the southwest.
East and down-dip from the copper zone is a zone of zinc mineralization with minor lead and copper, most recently intersected in several zones in hole CLS 97-24. There, a 4.5-metre intersection returned grades of 1.04% zinc and 3.7 grams silver; a 12-metre intersection showed 2.8% zinc, 0.12% copper and 51.6 grams silver; and a 2.2-metre intersection ran 0.15% zinc, 0.4% copper, 33.4 grams silver and 1.3 grams gold per tonne.
Results released earlier this month showed the zinc mineralization, believed to be a basin facies more distant from the main vent, occurs in three different zones. One occupies the stratigraphic footwall of the prospect, near the copper zone, and recent drill results show multiple intersections in each hole, with grades mainly around 1-2% zinc over core lengths of 1.5-6.5 metres.
A second zone, called the Main zone, is south of the footwall zone, and is interpreted as being stratigraphically above it. Recent intersections in the Main zone have mainly been in the 1-3% zinc range, also usually in multiple intervals down each hole. Cross Lake reported results from three holes on Dec. 10:
* CLS 97-20 intersected five zones, 1 metre to 10.6 metres long, with the widest grading 1.57% zinc, 0.69% lead and 16.5 grams silver per tonne.
* CLS 97-21 intersected four zones, 1.5 metres to 24 metres long, with the widest grading 2.16% zinc, 0.4% copper, 0.12% lead and 52.8 grams silver per tonne.
* CLS 97-22 intersected a single interval 52.4 metres long, with an average grade of 1.41% zinc, 0.19% lead and 10 grams silver per tonne.
Cross Lake expects to have results from nine additional holes shortly.
Golden Knight Resources (GKR-T) is completing further geophysical work and drilling on the adjacent property, where it holds a 60% interest earned from three companies: Cross Lake, which retains 16%, East West Resource (EWR-V), with 16%, and Canadian Golden Dragon Resources (CGG-V), with 8%.
Northeast of the Sheraton-Timmins projects, Moss Resources (MRS-T) and Greenshield Resources (GSR-M) have started geophysical surveys on their joint-ventured property in Currie and Egan twps. The companies are using induced polarization and ground electromagnetic (EM) surveys over anomalies detected in Ontario government airborne electromagnetic work. The companies are concentrating their investigations over weak EM conductors similar to those found over the Cross Lake mineralization.
