WPG Resources Ltd. provided an update on the development of Challenger Deeps with the commencement of the first ore drive on the 115 level at Challenger. Challenger Deeps is the down plunge continuation below the 215 shear of the heavily mineralised systems that have been mined successfully at Challenger over the last 15 years. Surface drilling undertaken in 2009 confirmed the continuation of these systems at least 280m vertical (or 560m down plunge) below the last stoping horizon on the 135 level of the mine. This stoping was undertaken on limbs of the M1/M2 structures with mining at that time constrained by the mining lease boundary. The new adjacent ML6457 allows unconstrained mining to proceed down plunge. During late 2017, following an upgrade of the mine ventilation system, diamond drilling targeting the next four production levels (115, 95, 75 and 55 levels) has been undertaken to provide increased data density for mine planning purposes. This drilling has targeted not just the limbs of M1/M2 mined on the 135 level but has also targeted other limbs and folds, including Challenger West, Aminus, M3 and SEZ that have never been mined previously below the 215 shear. This drilling has to-date provided encouraging results and are very similar to those in levels above the shear where multiple limbs and folds have been successfully mined at grades in excess of 5 g/t Au. Importantly these additional folds, outside of those assumed in initial mine planning, also have the potential to increase the ounces per vertical metre above those used for initial planning purposes. Waste development on the 115 level has been undertaken allowing development to target both the M1 and M2 stoping areas with the M2 S2 R development drive now entering the high grade ore zone. Both ore and waste development will continue with the first stoping of the M2 S2 limb scheduled in late February. Decline development is also progressing with the Jumbuck decline scheduled to reach the 95 level in late January.
