Bonanza Silver at Real Viejo

Minefinders (MFL-T) has hit high-grade silver while drilling at its Real Viejo project, about 30 km west of Nogales, in the state of Sonora, Mexico.

Five holes intersected multiple silver intercepts along a strike length of about 400 metres. Highlights of this include:

• 1.3 metres grading 634 grams silver per tonne, as well as 516 grams silver over 1.5 metres within an intersection averaging 158.7 grams over 27.5 metres, and in the same hole, 12.6 metres grading 131.8 grams silver at a downhole depth of 16 metres; and
• 9 metres grading 64 grams silver per tonne, that included 1.5 metres grading 182 grams silver per tonne.

Silver is associated with quartz stockwork veining in felsic and intermediate volcanic rock with local sedimentary horizons, adjacent to a diorite plug intruded by felsic dykes. The system outcrops over an area 300 metres wide by 600 metres long.

One hole primarily intersected a diorite plug and failed to intersect significant mineralization. Anomalous zinc was associated with the silver in one hole.

The Northern Sonora property consists of 10 exploration concessions, covering 150 sq. km. The Real Viejo prospect is near the centre of these. There has been small-scale mining of the Real Viejo, evidenced by small pits in the area, as well as some underground workings.

The company operates this project through its Mexican subsidiary Minera Minefinders. Drilling is ongoing at its Dolores deposit in Chihuahua State, Mexico.
