WPG Resources Ltd. announced that it has completed its 30 June 2017 Mineral Resource and Ore Reserve estimates for Challenger prepared and reported in accordance with JORC (2012) guidelines. The 30 June 2017 Mineral Resource estimate is a total of 1.6 million tonnes at an average grade of 7 g/t Au containing 364,000 ounces of gold. The 30 June 2017 Ore Reserves estimate is 537,200 tonnes at an average grade of 5.60 g/t Au containing 96,755 ounces of gold. The contained gold in the updated mineral resource estimate of 364,000 ounces is 6% higher than that shown in WPG's 31 March 2017 resource estimate announced by the Company on 1 June 2017 and 38% higher than the 30 June 2016 Mineral Resource estimate announced on 25 October 2016. The increase in gold contained in the 30 June 2017 resource estimate compared with that of the 31 March 2017 estimate is due to depletion of the previous resource estimate by way of production during the period April 2017 - June 2017; Small decrease in the M2 resource due to production from remnant areas included in the resource (usually while accessing M3); An increase in the M3 resource due to the effect of positive drilling returns around the 1,055 level and the inclusion of M3 resource in lower levels of Challenger. The Resource Estimate for the Challenger deposit is based on the interpretation of the geology and gold bearing lode structures that has been developed as a continually evolving model by hands-on experienced site geologists before and since the commencement of mining in 2002. The Challenger deposit extends from 1,193mRL (surface) to -325mRL as a series of gold bearing folded migmatite zones with ore shoots that plunge at ~30 degrees on a bearing of 029. The cut-off grade used in the Resource Estimate is 3.0 g/t Au for underground lodes and >1.5g/t Au for open pit lodes and is based on what is considered an economic cut-off in relation to the prevailing gold price and projected operating costs. All sludge samples are submitted as entire samples to the site laboratory for analysis. Any intercepts over 10.00g/t Au over 1.00m are considered significant and along with adjacent samples (generally three on either side) are submitted to an external laboratory for check analysis as required. Face chip samples are collected to be as representative as possible of the source material. These 2-5kg samples are all processed by the site laboratory. The Ore Reserve estimate is at 30 June 2017. The Mineral Resource estimate is inclusive of the Ore Reserves. Challenger ore reserves estimated herein have been derived from measured and indicated Mineral Resources. The Ore Reserve estimate does not include any inferred Mineral Resources. The contained gold of 96,755 ounces is a 7,307 (7.5%) ounce net increase to the June 2016 Ore Reserve estimate of 89,448 contained ounces of gold. Challenger has been a fully operational underground mining operation other than a period between January 2016 to May 2016 when underground operations were suspended by prior to the operation being acquired by WPG. The Challenger Resource models were used to create detailed life of mine designs for the extraction of each Resource lode.
