The first phase of this season's field work at Wellgreen started with a re-sampling program on up to 12,000 metres of historic drill core that was previously only selectively sampled for very high grade, massive sulphide material. 75% of the drill hole core from the potentially bulk mineable ultramafic hosted mineralization was never sampled. These historic holes are now being analyzed from this bulk mineability perspective across broad zones of disseminated mineralization for platinum, palladium, rhodium, and gold (4E) in addition to nickel, copper, cobalt and trace elements. The analysis will include NI 43-101 quality control processes to allow these historic drill holes to be utilized in the next mineral resource update and revised PEA.
This re-sampling program highlights the contrast between the historic model which focused on narrow, very high-grade zones in the deposit and the current approach which looks at potential open pit and bulk mineable underground production. This low-cost, high-impact re-sampling program will allow for better assessment of bulk mineability across a large area of the deposit and has the potential to define new zones of mineralization that have not been previously recognized (see figure below). Samples from the East and Far East Zones (E and FE) and North Arm have been submitted for analysis with broad visually mineralized intervals of ultramafic intrusive rocks. First results from this re-sampling program should be available within the next 4 to 6 weeks.

Our 2013 drill program will be conducted by Boart Longyear Canada Inc. and, as noted above, has the following key objectives:
-- Definition of higher-grade mineralization for scheduling in the first 5- 10 years of operations to improve existing positive economics;-- Key step-out drilling to offset higher-grade mineralized zones and bring currently unclassified blocks that are within the previous pit model into the mineral resource;-- Conversion of a significant portion of the mineral resource from Inferred to the Measured and Indicated category to increase overall confidence in the mineral resource model; and-- Testing of high priority, road-accessible targets adjacent to the main Wellgreen deposit for the existence of new, higher-grade, bulk mineable mineralization.
Two areas, the Far West Zone (FW) and the Far East Zone, demonstrate wide intervals of mineralization that are of significantly higher grade than the average of the deposit. These will be assessed in order to determine whether they can potentially be accessible and scheduled within the first 5-10 years of operation.
The Far West target, which begins at surface, is significantly enriched in PGMs and is as much as three times higher than the average grade. The Far West Zone is at the western end of the deposit and is open to expansion down dip. In addition, geophysical surveys in the Far West indicate the potential for an untested parallel zone. The Far West and West (W) areas both contain higher grade material which will be further investigated to determine potential suitability for location of possible starter pits.
A second higher grade target area occurs within the Far East Zone at the eastern end of the main Wellgreen deposit. Modeling and compilation of historic drill holes has identified a thick mineralized zone which appears to occur in this area to the north of the main tabular Wellgreen deposit. This zone is completely open to the east and may connect the main Wellgreen deposit with the nearly untested North Arm ultramafic body. The North Arm falls within the current pit model but, due to a lack of modern drilling data, is not included in the current mineral resource estimate. This area has the potential of being reclassified from waste material into a mineral resource designation, adding to the economics of the Wellgreen project. The areas to the east and north of the main deposit hold potential for expansion of the mineral resource, with some of the best holes drilled in the deposit to date in these areas.
