The Geel Property

The Geel gold and silver mine property covers a portion of the Geel trend, a quartz vein system, that has been traced for over 4 miles (6.4 km). The property hosts a small high grade gold and silver mine that has seen limited historical production. There are no records available to quantify the tonnage and grade produced.

Cougar Minerals completed a 19 hole core drill program earlier this year (refer to Cougar Minerals press release dated April 5th 2013). Previously announced hole G7 intersected 5 ft (1.5 metres) (true width) averaging 1.23 opt gold (42.17 g/t Au) and 1.88 opt silver (64.46 g/t Ag). This included a 1 ft (0.3 m) interval averaging 5.9 opt gold (202.29 g/t Au) and 8.8 opt silver (301.71 g/t Ag).

These drill results combined with sampling results from the Geel adit (also announced in the Cougar Minerals Press Release dated April 5th 2013), indicate good grades over a strike length of at least 200 feet (61 metres) and down-dip 140 feet (42.6 metres) below the surface. Mineralization on the vein still remains open for expansion at depth and to the south.
