Encouraging Sample Results at La Cigarra Silver Project
The first of the three zones sampled by Northair, the San Gregorio Zone lies in the central portion of the property and contains two distinct areas referred to East Hill and West Hill. East Hill contains mineralization exposed through limited outcrops and mine workings over a northwesterly trending zone of approximately 185 by 50 metres, dipping moderately to the northeast. Mineralization occurs as vein swarms, stockwork, and dissemination in sediments intruded by altered rhyolites dykes and sills. To date, Northair has taken a total of 32 chip samples from East Hill, ranging in widths from 1.5 to 15 metres, with an average width of 4.3 metres. The 32 samples reported an average grade of 180 g/t silver including a low of 10 g/t silver over a width of 4 metres and a high of 991 g/t silver over a width of 3 metres.
West Hill, located parallel to the structural fabric of the East Hill area and 80 metres to the southwest, contains a northwesterly striking, moderately northeasterly dipping vein system. The main vein is open in both directions and has been traced on surface over a strike length of approximately 340 metres with exposed widths of mineralization that range up to 15 metres. To date, Northair has taken a total of 28 samples from surface outcrops and historic mine workings that range in sample width from 1.0 to 6 metres, with an average width of 3.3 metres. The 28 samples reported an average grade of 187.3 g/t silver, including a low of 12.9 g/t silver over a width of 3 metres and a high of 660 g/t silver over a width of 2 metres.
