Nunavut

URANIUM – Kivalliq Energy Corp. Sept. 11 provided an update on metallurgical and beneficiation studies for the company’s 137,705-hectare (340,268 acres) Angilak property in Nunavut. The update summarizes preliminary results from work performed on the Lac 50 Trend deposits, including metallurgical testing of the J4 and Lac 50 zones as well as characterization studies related to optimal ore sorting methods. “Results from ongoing metallurgical work at Lac 50 are encouraging,” said Chuck Edwards, director of Metallurgy at AMEC. “Optimizing sulphide recovery, plus improvements to alkaline leach kinetics using oxygen as oxidant, could have a positive impact on reducing costs associated with potential treatment options.” Among key findings: J4 Zone flotation achieved an optimum sulphide recovery of 99.2 percent in alkaline solution at a grind size of 100 percent passing 140 mesh (106 µm); positive alkaline leach results on J4 Zone indicate rapid uranium extraction – 92.3 percent in 12 hours, 95.2 percent in 24 hours and 96.7 percent in 48 hours; using improved alkaline leach parameters defined by the J4 Zone testing, retesting of the 2012 Lac 50 composite upgraded the leach extraction of uranium to: 91.7 percent in 12 hours, 95.1 percent in 24 hours and 96.4 percent in 48 hours; J4 Zone sulphide flotation and alkaline leach results are consistent with other Lac 50 deposits; and preliminary ore sort characterization of rock specimens from Lac 50 deposits indicates that radiometric sorting will be very effective. Radiometric characterization analysis demonstrates a 56 percent reduction in mass with 98 percent U3O8 recovery. Pleased with the success of preliminary radiometric sorting, Jeff Ward, president of Kivalliq Energy said larger bulk testing using production-scale sorting methods will now be considered as a processing option to concentrate uranium-bearing rocks at Lac 50.

URANIUM – Kivalliq Energy Corp. Sept. 9 provided an update on activities conducted as part of its 2013 season at the 137,705-hectare (340,268 acres) Angilak Property in Nunavut. Assays received from 1,538 geochemical samples collected within the Lac 50 Trend, and directly to the south in the Angikuni sub-basin, have identified new anomalous zones and prioritized existing zones for future exploratory and resource drilling. The 2013 sampling program was designed to test the effectiveness of soil geochemical surveying within the Lac 50 Trend using a widely spaced sampling pattern. Given its success, Kivalliq said a larger and more detailed future work program is justified. Some 387 anomalous uranium soil geochemical results (using a 75th percentile threshold) were reported over the entire width and length of the 12-kilometer- (7.44 miles) Lac 50 Trend, and along the new Nine Iron-KU Trend situated 5.5 kilometers (3.4 miles) to the south. Anomalous values using the Enzyme Leach method ranged from 6.5 parts-per-billion to 2,880 ppb uranium, with the highest assays corresponding to both known mineralization and high-priority geophysical targets not yet drilled. Key uranium-in-soil anomalies occur at least 850 meters along strike in both directions from the J4/Ray inferred resource and as a 500-meter-wide by 2,600-meter-long trend at the high-priority Hot Zone. “The results from this targeted geochemical sampling program increase our confidence in the exploration potential of specific geophysical conductors along the entire Lac 50 Trend and have also prioritized several new geophysical targets,” said Kivalliq President, Jeff Ward. “When interpreting these geochemical results, we have the advantage of knowledge gained through our exploration efforts over the past six years within the Lac 50 Trend. We will leverage this increased understanding to maximize our success in the 2014 exploration campaign.”

DIAMONDS – Peregrine Diamonds Ltd. Sept. 9 provided an update on activities at its Chidliak Project located on Baffin Island. The Chidliak summer exploration program operated by De Beers Canada Inc. was completed on Aug. 19. Highlights from this program include the discovery by De Beers of two new kimberlites and the discovery of a kimberlite dyke by government geologists. In addition, possible kimberlite float, which is undergoing final petrographic confirmation by De Beers, was found in numerous other locations. As reported on April 23 and June 5, 2013, Peregrine collected a bulk sample weighing roughly 508 wet metric tons from the CH-6 kimberlite by surface trenching. About 470 wet metric tons of this sample has been transported from Iqaluit to the De Beers dense media separation facility in Sudbury, Ont. Ten wet metric tons of kimberlite was processed at the Saskatchewan Research Council in July and roughly 28 wet metric tons of kimberlite material that remains in Iqaluit will be shipped to Sudbury this month. Processing of about 250 wet metric tons of the bulk sample by DMS is scheduled to commence in late September at the De Beers DMS facility. This processing will be performed by De Beers and is expected to yield a heavy mineral concentrate weighing about 1.8 dry metric tons. Final diamond recovery from this concentrate will be managed by Peregrine and will be undertaken at the SRC. The final diamond recovery process will be initiated upon De Beers delivering to the company notice of their decision regarding their right to enter into an earn-in and joint venture agreement for Chidliak. The De Beers summer exploration program at Chidliak included the evaluation of priority geophysical anomalies by prospecting, orientation geophysical surveys, and bedrock and surficial mapping. During the course of the program, De Beers field teams discovered two new kimberlite occurrences and numerous occurrences of possible kimberlite float requiring additional work before being confirmed. The first confirmed discovery is a kimberlite dyke approximately one meter wide associated with a circular magnetic anomaly with an estimated surface expression from ground magnetics of approximately 0.5 hectares. At the second site, kimberlite float was found associated with a circular geophysical anomaly that has an estimated surface expression from airborne magnetics of approximately 0.5 hectares. Concurrent with the De Beers Chidliak exploration program, the Canada Nunavut Geoscience Office conducted a bedrock and surficial mapping program over a portion of the Hall Peninsula of Baffin Island. During the course of their fieldwork, the CNGO reported the discovery of a new kimberlite dyke on the Project. In total three new confirmed kimberlites have been discovered in 2013 bringing the total number of kimberlites at Chidliak to 64. De Beers completed ground geophysical orientation surveys over 12 known kimberlites using the following methods: gravity, electromagnetics, ground penetrating radar and magnetics. The results from these surveys will be used to determine the most effective geophysical technique for discovering additional kimberlites in future exploration programs. To date initial results from the gravity surveys have been reviewed by Peregrine and indicate that most of the known kimberlites that were surveyed have a strong gravity response. Prior to this year, no gravity surveys had been executed on the Project. Peregrine believes that gravity could play a key role in future kimberlite discoveries at Chidliak. A complete summary of the summer exploration program, including confirmation of additional kimberlite discoveries, and results from the other geophysical surveys will be provided after all information from the program has been evaluated by Peregrine.
