SOUTH KOREA - Encouraging Sangdong results
This program is targeting the unmined ore in the upper portion of the mine. This Main Zone is made up of the inclined shaft, infrastructure pillars, the Hangingwall and Footwall Zones above the current water level.
The tungsten-molybdenum mineralization at Sangdong is hosted within three parallel, shallow-dipping skarn zones (Main, Hangingwall and Footwall) with a lateral extent of up to 1200 metres along strike and 1500 metres down dip.
Best results from the three holes are: 10.1 metres from 8 metres @ 0.51% tungsten and 0.04% molybdenum, including 5.1 metres from 13 metres @ 0.88% tungsten and 0.06% moly; 7.3 metres from 40.5 metres @ 0.38% tungsten and 0.03% moly, including 2.3 metres from 45.5 metres @ 0.94% tungsten and 0.03% moly; and 2.5 metres from 130.5 metres @ 0.83% tungsten and 0.01% moly, including 1 metre from 130.5 metres @ 1.7% tungsten and 0.6% moly, and 2 metres from 144 metres @ 2.42% tungsten and 0.08% moly.
Woulfe's president and CEO Brian Wesson says, “Spring has arrived and we are now working unhindered to achieve our goals of completing the drilling, mine plan, feasibility and detailed design this year. We are working on the geology and mining plan with personnel from Wardrop as we progress the project.”
The central Main Zone, being high grade, was largely mined out during previous production apart from support pillars and protective areas around infrastructure mainly in the top and margins of the lodes. The overlying Hangingwall Zone and underlying Footwall Zone are largely intact. The NI 43-101 resource estimate undertaken in early 2010 by Wardrop UK, a Tetra Tech Company, as part of the scoping study, totalling 103.2 million tonnes @ 0.35% tungsten and 0.04% moly, included only the Hangingwall and Footwall Zones.
Woulfe is utilizing seven rigs to accelerate the program to offset the delayed start due to restrictions caused by equipment delays and the severe winter. This includes four contract surface rigs, a contract underground machine and two company-owned underground machines, mostly working around the clock.
The drilling is on track to be completed by the end of May and an updated NI 43-101 resource statement is to be published by the end of June to underpin the feasibility study.
