As at May 31, 2011, 15 trenches totalling 1,200 linear metres have been completed with 215 samples collected over 5m sample intervals from the trenches at the Tesoro Project. The trenches were completed by a backhoe and a track-mounted excavator at Zona Central (Main Structural Corridor) and Zona Este (Parallel Structural Corridor)
They are not using shovels and buckets no more.
