Continental Precious Minerals Inc. (TSX:CZQ) announced today that an NI 43-101 compliant mineral resource has been estimated on the 100% owned Lill-Juthatten Licence, located in northern Sweden.
The Lill-Juthatten uranium deposit is located approximately 600 kilometres northwest of Stockholm at an elevation of about 700 metres above sea level, in an area close to the Norwegian border.
The Lill-Juthatten Licence is an advanced stage exploration prospect with gridded, resource definition drilling having been carried out in the late 1970s and early 1980s by the Sveriges Geologiska Undersökning or the Geological Survey of Sweden (the "SGU") and associated state companies. Uranium mineralization occurs in the form of pitchblende disseminated in granite, and occasionally up to 5 millimetre joint filling in a breccias/fault zone. P&E Mining Consultants Inc., G.A. Harron & Associates Inc. and MPH Consulting Limited prepared the updated mineral resource estimate in compliance with National Instrument 43-101.
"It is important to note that in addition to our flagship property, MMS Viken, we have several other high potential properties like Lill-Juthatten," said Ed Godin, President and CEO. "It is one of several hard-rock uranium targets we have. All have been drilled previously by the SGU and have resource estimates that can be confirmed and further defined."
The key assumptions, parameters and methods used to estimate the mineral resource are as follows:
The resource estimate is effective as of March 1, 2011 and takes into account the results from a total of 91 holes drilled by the SGU in the late 1970s and early 1980s (13,245 metres) and two holes drilled by Continental (approximately 400 metres) on the Lill-Juthatten deposit. The spacing of the drill holes is nominally 25 metres. The deposit has a strike length of 300 metres and a down dip extension of 135 metres. Average width is approximately 15 metres but some sections of mineralization exceed 50 metres.
P&E Mining Consultants Inc. calculated the updated open pit mineral resource estimate using an average internal cut-off grade of 0.035%U based on processing costs of US$30 per tonne, process recovery of 90%, G&A costs of US$10 per tonne and mining costs of US$5 per mineralized rock tonne and US$4 per waste rock tonne. The uranium price used in the estimate was US$55.00 per pound U3O8, which is equivalent to US$65 per pound U. Block model grades were interpolated with the inverse distance squared (1/d2) method from one metre composites derived from U assays capped at 3%U. Potentially economic resources were contained within a conceptual optimized pit shell with 50-degree slopes.
Due diligence sampling of historical core was undertaken in January 24-29, 2011 in order to validate the analytical data supplied by the SGU. Neutron activation analysis was conducted by Studsvik Energiteknik AB, between 1977-1983 and original laboratory certificates were available for assay data capture. Fourteen verification samples were taken and analyzed by ALS Chemex in Vancouver. The ALS Chemex results are in good agreement with the original neutron activation analyses and confirm the presence and grade of uranium mineralization at Lill-Juthatten. The quality of historical analytical data is therefore assumed to be good, based on the results of verification sampling and the reputation of the SGU.
The Lill-Juthatten licence was initially granted on March 3, 2005 and was renewed on March 3, 2008 for an additional three-year term, which ended on March 3, 2011. Continental filed a renewal application in February 2011. Given the large backlog of applications being handled by the Swedish Inspectorate of Mines, Continental believes that the renewal will not be received by Continental for at least four months. Continental has no reason to believe that the renewal will not be granted.
