Northcliff will undertake value���added processing of tungsten concentrates produced at Sisson by constructing and operating an APT plant at the project site which adds significant economic value to the Sisson Project. Access to this site will be via existing highways and roads, with power provided by provincial power utility NB Power. Initial capital construction costs are estimated at CDN $579 million. The project is expected to be a two-year build.�� The mine plan designed employs variable cutoff grade strategies to maximize returns. Mill throughput production is planned to average 30,000 tonnes/day for a total of 291 Mt of ore processed over the 27-year mine life. Recovery is expected to be 77% for tungsten and 82% for molybdenum. Long term metal prices have been estimated at $350/mtu for WO3 and $15/lb for Mo concluding that Sisson will be a stable and profitable producer of tungsten and molybdenum throughout the mine life as detailed in the market study completed for Northcliff by Roskill Consulting group of London, U.K.�� Roskill states that, ���Tungsten production costs have been rising globally and Chinese producers are now more sensitive to tungsten prices than in the past because of rising energy, labour, equipment and reagent costs. In real price terms, APT prices are forecast to average $383/ mtu in the period 2012 to 2025, reaching $433/mtu in 2025.��� With this prognosis Northcliff has a very bright future ahead with its Sisson Project. URANIUM MINERALIZATION INTERSECTED AT ALPHA MINERALS PATTERSON LAKE PROPERTY Alpha Minerals Inc. [AMW-TSXV] announced on 19 February the results from their Patterson Lake, Saskatchewan, drill program. The property is in a partnership joint venture with Fission Energy MARCH 2013 Corp. [FIS-TSXV] and includes 17 claims (approximately 25,450 hectares) that straddle the southwestern margin of the Athabasca Basin. The property is accessible by road with primary access from Highway 955, which runs north to the Cluff Lake Mine, a former U3O8 producer. The deposits that comprised the Cluff Lake Mine were located by following up on uranium boulder fields. These fields are significantly smaller than the ones discovered by the Patterson Lake Saskatchewan drill program, which, to the companies��� knowledge, is the largest-known boulder field in the region. Core drilling continues to define the mineralized region identified during the summer 2012 program. Intersections of high-grade (up to 12.5 metres at 2.49% U3O8 mineralization) were announced in November 2012 and have been followed up with drilling 385 metres east of that hit. High-grade U3O8 mineralization was intersected in the PLS 12-038 hole at over 57.5 m, as well as 15.5 m of intermittent uranium mineralization at this eastern target. The drill hole location was selected from anomalous radon result from a survey of lake water that noted three broad anomalous areas, one of which resulted in the high-grade PLS 12-038 target. The third anomaly will be drilled in the future. Gamma logs of the drill holes include high point readings of 76,233 cps in the highest grade zone, with other high-grade sections at 20m from 87-107 m at greater than 10,000 cps and 9 m from 96-105m down hole greater than 45,000 cps. SEAFIELD RESOURCES LTD INTERSECTS GOOD GRADES IN COLOMBIA. Seafield Resources Ltd. [SFF-TSXV] announced on February 15, 2013 the results from five additional drill holes completed at their Miraflores deposit in the Quinchia District, Colombia. The five drill holes are part of the 6,800-metre diamond drill program currently being completed on the property. Results included intercepts of 238.15 m at 2.06 g/t Au and 1.82 g/t Ag, including 59.2m at 5.72 g/t Au and 3.31 g/t Ag in hole QM-DH-50. Good grades were also intercepted in drill hole QM-DH-51 with 119.1 m of 1.34 g/t Au and 4.66 g/t Ag, from 1.9 m to 121.0 m; including 20.9m at 4.68 g/t Au and 2.83 g/t Ag, confirming continuous mineralization near surface. The deposit is a hydrothermal breccia pipe, with a drill-tested strike-length of 280 m by 250 m, with a vertical extent open at depth, but defined to 600 m. Seafield published a NI 43-101 compliant report on the property in Q4 2011, which defined resource estimates of indicated 1,925,542 oz Au, and an inferred 103,043 oz Au. A Preliminary Economic Assessment (PEA) completed mid-2012 highlights robust economics as illustrated by a pre-tax IRR of 50% and an NPV 8% of $249 M. Future and ongoing plans for the property include baseline environmental studies, geotechnical studies, surface rights, the commencement of an 8,000metre drill program, updated NI 43-101 resources estimate, updated PEA, an Environmental Impact Assessment, and a Feasibility Study. The company hopes to begin development in 2014, with production scheduled for 2015. n www.resourceworld.com 39
