Data Verification

The data verification procedures applied by various qualified persons at the Sangdong Mine since 2006 are summarized below.

Watts, Griffis and McQuat (2006)

The Sangdong Mine underground workings were either inaccessible or, if open, of unknown condition. This restricted Watts, Griffis and McQuat’s (“WGM’s”) independent sampling to low-grade outcrops and waste dump material. Given the long-documented record of tungsten production at the mine, the sampling done during WGM’s site visit on November 20, 2006 was clearly not intended to be definitive, rather simply to independently confirm that economically significant grades of tungsten, in particular, were present.

All samples were put into bags and closed with uniquely numbered, locking plastic ties; they remained under lock and key or in WGM’s possession during their representative’s time in South Korea. They were taken as personal baggage to Mississauga, Ontario and shipped by courier to SGS Mineral Services (“SGS Canada”) in Lakefield, Ontario. Samples were assayed for tungsten (reported as %WO 3) and molybdenum.

SGS Canada normally inserted one blank per batch of 100 (maximum) samples, one duplicate per 20 samples and one reference standard every 20 samples.

After drying, if necessary, the samples were crushed to 75% passing 9 mesh (2 mm), and riffle split to produce a reject portion and a smaller portion which was pulverized to 85% passing 200 mesh (74 μm). A 0.2g charge of each pulverized sample was roasted for 20 minutes and mixed with 5 g of potassium pyrosulphate. The mixture was then fused, ground and pressed into a disk. Samples were analyzed by the wavelength dispersion X-ray fluorescence (WD-XRF) method having detection limits of 0.05% for each of W and Mo. The XRF method was chosen because normal ICP methods have an upper detection limit of 1% W, and it was suspected that at least two of the Sangdong samples contained appreciably more than this amount of tungsten.

Analytical results for the independent WGM samples, together with location and sample descriptions, are presented in Table 12-1 below.
