The mineral resource was estimated using the inverse distance squared method. Block dimensions were 25 metres by 25 metres horizontal and 10 metres vertical. Grade estimation was based on analyses of core samples from 14 vertical core holes (1088 metres in total) completed in 2012. Drill holes were spaced approximately 100 metres apart on a rectangular grid and extended between 50 and 100 meters below surface. Oxide analyses were composited in five metre down-hole intervals. It was concluded from statistical analysis of the raw sample data that grade capping or special treatment of outliers was not warranted.
Blocks were considered as potentially economic if they were within an area mapped as being greater than 90% anorthosite and containing less than 2.5% Na2O. Almost all blocks exceeding this level of Na2O were at the base of the model and would not have to be removed to access the other material. No other cut-off criteria were used as all blocks were within the anorthosite and are considered potentially economic.
Blocks were classified as 'Indicated' if they were within the bounds of the drill grid or within 50m of the boundary. Blocks were classified as 'Inferred' if they did not meet requirements for 'Indicated' and were located up to 100 meters beyond the drill pattern.
White Mountain is a weakly metamorphosed calcic anorthosite composed of nearly monomineralic high-calcium plagioclase (bytownite An80-85) with minor amounts (less than 1%) of clinozoisite and muscovite. The anorthosite body is lenticular in shape with an east-northeast structural trend, covering a surface area of over 20 square kilometers.
Hudson plans to commence additional diamond drilling starting in June of this year with the objective of adding additional tonnes and upgrading the resource to the measured resource category from the indicated resource category which will be included in the the application for an exploitation license.
Hudson's White Mountain anorthosite is relatively unique in that it has high concentrations of aluminum, silica and calcium, with little to no contaminants and low iron. Hudson has determined that the White Mountain anorthosite has three potential high-value industrial applications:
1. As a new source of alumina to supply aluminum smelters;2. As a new source of feedstock to the high end fiberglass (E-glass) industry; and3. As a new source of filler material. Fillers are a significant component in the plastics and paints industries.
Hudson commenced exploration on the White Mountain Project in January 2012 and has completed over 4,300 meters of drilling in 45 drill holes at White Mountain. Processing of the 122 tonne bulk sample has been initiated at the Saskatchewan Research Council's pilot plant in Saskatoon. Based on bench scale testing, the material requires minimal processing: crushing, grinding, magnetic separation and milling. The processed bulk sample material will be provided to potential end users in the E-glass industry for testing in their furnaces. The Company has also initiated baseline environmental studies with the objective of submitting an application for a mining license in early 2014.
As reported in the Company's press release dated January 23, 2013 (NR2013-02), aluminum leaching testwork has begun at SGS Canada Inc, with initial leach recoveries of 94% of the aluminum being achieved. Downstream testwork on leach solutions is ongoing and includes aluminum chloride precipitation, alumina production and acid regeneration testing. Once this testwork is completed, Hudson will initiate a scoping study to determine the preliminary economics of producing an alumina product and potential by-products, including silica and a calcium compound.
The White Mountain Project is owned 100% by Hudson. The Project is located on tidewater approximately 40 km from the Company's 100% owned rare earth element (REE) project. White Mountain is envisioned as an open pit mining operation similar in scope to a quarry. The Company remains well-financed with approximately $7 million in working capital.
