Defense Metals Corp. provides operational update on Wicheeda
Defense Metals Corp is pleased to announce that Phase 1A metallurgical testing on the Wicheeda bulk sample at SGS Labs is underway.
Defense Metals Corp has been informed by SGS that the entire 30 tonne bulk sample has been crushed to a nominal 1 inch size and a 400 kg subsample has been taken for batch and grindability tests. Preparation is underway to prepare a grindability sample, flotation charges and head assays, which is expected to be completed early this week. The subsample from the head will be submitted for chemical and mineralogical analysis is also scheduled for early this week as well.
Chris Graf, Technical Advisor comments "Building on the successful bench scale flotation testwork conducted in 2012 by SGS on a 100 kg composite sample of Wicheeda drill core, the goal of the Phase 1A testwork is to develop a robust flow sheet for producing high grade REE flotation concentrates from a 200 kg sample of the 30 tonne Wicheeda REE deposit bulk sample. It is anticipated that 20 kg of REE concentrate will be produced by Phase 1A."
Following a successful Phase 1A, Phase 1B hydrometallugical testwork is to commence on the 20 kg sample of flotation concentrate once it has been produced, by the end of May. The goal of this hydrometallurgical testwork will be to produce a purified, mixed REE concentrate and provide data that can be used to design a hydrometallugical pilot plant.
The Phase 1A flow sheet will be used in a Phase 2 flotation concentrate pilot plant program where the entire 30 tonne Wicheeda bulk sample will be processed with the goal of demonstrating that the Phase 1 A flowsheet is capable of producing a high grade REE concentrate at an industrial scale. It is expected that the Phase 2 pilot plant metallurgical testwork will produce approximately 3 tonnes of REE concentrate that can be tested by a Phase 3 hydrometallurgical pilot plant.

About The Wicheeda Property
The property located approximately 80 km northwest of the city of Prince George, British Columbia, is readily accessible by all-weather gravel roads and is close to major infrastructure including nearby working power transmission lines, railway and major highways. Geologically, the property is situated in the Foreland Belt and within the Rocky Mountain Trench, a major continental geologic feature. The Foreland belt contains part of a large alkaline igneous province stretching from the Canadian Cordillera to the southwestern United States and hosts several carbonatite and alkaline complexes among which are the Aley (niobium), Rock Canyon (REE), and Wicheeda (REE) alkaline complexes that contain the highest concentrations of Rare Earth Elements minerals.
The Property is underlain by Kechika Group metasedimentary rocks that are intruded by a southeast-trending carbonatite. The Wicheeda carbonatite is a deformed plug or sill approximately 250 metres in diameter that hosts potentially economic REE mineralization. The intrusion comprises a ferroan dolomite carbonatite core, which passes gradationally outward into calcite carbonatite. The potentially economic REE mineralization is hosted by the dolomite carbonatite.
