COGITORE Resources Inc.. (the "Company") (TSX VENTURE:WOO) is pleased to report that infill drill holes on the Central Lens intersected the highest grades and thickest massive sulphide intervals ever for this lens. Vertical depths range from 200 metres to 250 metres.
Highlights:
- 3.0% copper, 12.3% zinc, 0.3g/t gold and 74g/t silver over 5.0 metres;
- 1.0% copper, 6.8% zinc, 0.1g/t gold and 38g/t silver over 15.5 metres
The locations of the piercing points of the holes are shown on Figure 1(click here). The new holes were drilled on vertical sections 50 metres apart and details are shown by section going from west to east in the table below:

All of the above assay intervals are weighted averages of several individual assays. The true thickness is estimated to be between 60% and 70% of the core lengths. The current interpretation suggests two sub-parallel east-west trending massive sulphide bands, namely an Upper (north) zone and a Lower (south) zone, dipping about 80-85° to the north and separated by a mafic intrusive (dyke) sub-parallel to the sulphide units. The infill drilling on 50 metre centres was done to enable mineralization in Central Lens to be included in the forthcoming NI43-101 resource update (due mid-June).
Central Lens massive sulphide mineralization is best developed between sections 1500W and 1300W. Central Lens mineralization is associated the Selco Rhyolite, but in detail massive sulphides are primarily hosted between mafic dykes or sills, which dilate or separate the massive sulphides into two prominent zones per section. The reported assay results include small internal sections of mafic dyke at zero grades.
Central Lens is one of six massive sulphide lenses discovered to-date over a two kilometre long plunge length. From east to west the lenses are:
- Selco-Scott Lens (Scott Rhyolite), lens sub-crops, historic resource estimated to 400 metres depth
- "800" Lens (Scott Rhyolite), vertical depth to top of lens is 550 metres
- Central Lens (Scott Rhyolite), vertical depth to top of lens averages 220 metres
- "34" Zinc Lens (Scott Rhyolite), vertical depth to top of lens is 380 metres
- West Lens (Scott Rhyolite), vertical depth to top of lens is 400 metres
- CFO Lens (Tony Rhyolite), vertical depth to top of lens is 900 metres
The Scott project's first NI43-101 compliant resource, 3.6M tonnes, 1.1% copper, 5.2% zinc, 0.3g/t gold and 36g/t silver (released November, 2009) includes only mineralization from three lenses, i.e. West, '34' Zinc and '800'. The updated resource estimate due mid-June will add mineralization from the CFO and Central lenses for the first time as well as add to the existing resource associated with West Lens.
The Selco-Scott Lens sub-crops and was the first copper, zinc–rich sulphide mineralization found in Scott Township. A non-compliant resource of 0.7M tonnes of 0.4% copper, 6.9% zinc to a depth of 400 metres is attributed to this lens, but will not form part of the updated NI43-101 resource estimates scheduled for release in Q2.
Work is carried out by the Company's personnel, under the supervision of Gérald Riverin, PhD, P.Geo. He is a qualified person (as defined by National Instrument 43-101) and has more than 30 years of experience in VMS exploration.
All drill core discussed in this press release was logged and marked up for assay at the Company's secure facility in Chibougamau, Quebec. Drill core for assay was split in half. Half of the core was shipped in sample bags to either ALS Chemex of Val d'Or or Laboratoire Expert Inc. of Rouyn-Noranda with appropriate standards, duplicates and replicates used for quality control purposes. The other half of the core is retained for future reference.
The Company has developed a strategic focus on base metal exploration in prospective areas that also feature infrastructure favourable for mining development. Accordingly, it will focus its work in the Abitibi Belt of Quebec and Ontario.
