Woulfe Mining, a Canadian company with mining licenses for gold, tungsten, uranium-vanadium and molybdenum in South Korea, has announced the assay results for three sample batches of the Sangdong drilling program completed in 2011. The results will be used to estimate Feasability Study resource.
This released assay results include the results from 17 holes, eight of which were drilled to test the Main Zone from the Taebaek Level while the remaining nine were drilled to test the Footwall Zones from the Sangdong Level. Three of the 17 holes were abandoned due to unsuitable ground conditions. A total of six main and nine footwall intersections were recorded. The Footwall Zone intersections include 4.6 m true width at 0.98% WO3 for hole WSDD0071 and 11.9 m true width at 0.44% WO3 for hole WSDD0069. The Main Zone intersections include 5.3 m true width at 0.49% WO3 for WSDD0080 and 3.9 m true width at 1.04% WO3 for WSDD0047.
For feasibility reserve estimation and mine planning, the drilling program is focused on the unmined mineralization located in the mine’s upper section above the #2 level. Recent re-estimation of the section indicated resource of approximately 16.4 Mt at 0.04% MoS2 and 0.45% WO3 along with an inferred resource of about 19.4 Mt at 0.05 percent MoS2, 0.44% WO3 as well as a cut-off of 0.2% WO3.
The samples, prepared on-site were sent for analysis to SGS Perth, Australia. The analysis of the samples was done using inductively coupled plasma mass spectrometry.
