Abstract
At the San Gregorio vein, development since the last update (GPR news release January 26, 2009) includes further advance west on the vein which includes a portion measuring 100 metres along strike averaging 1,949g/t silver, 0.28g/t gold, 10.36% lead, and 17.68% zinc over an average 0.54 metre width. In addition, sub-level development and stoping has commenced further west from the aforementioned vein portion and averages 1,809g/t silver, 0.41g/t gold, 5.84% lead, and 14.76% zinc along a 70 metre strike length, with an average 0.34 metre width. Further development of the San Gregorio vein to depth is being planned. There is a 300 metre strike length of high grade mineralization on the San Gregorio vein and a series of old workings by a previous operator follow the vein another 450 metres WSW. Further to the WSW, the San Gregorio Vein has been traced on surface for about one kilometre more, bringing the total known strike extent to about two kilometres. Other productive veins in the Topia District extend for 3 to 4 kilometres along strike.
On the 1500 level, 170 metres of new development eastward along the strike length of [Don Benito] North averaged 654g/t silver, 1.67g/t gold, 6.57% lead, and 12.33% zinc with a thickness of 0.56 metres. Parallel development, about 5 metres south, and along 100 metres strike of the Don Benito South vein averaged 977g/t silver, 3.82g/t gold, 14.4% lead, and 19.81% zinc with a thickness of 0.41 metres. On the 1534 level, new development along a 104 metre strike length of the Don Benito North vein averaged 573g/t silver, 2.87g/t gold, 14.8% lead, and 15.48% zinc with an average thickness of 0.61 metres. Development on the 1534 level of the Don Benito South vein has not yet commenced pending the arrival of new underground equipment.
