Secutor Capital Management Corporation update on Commerce Resources Corp. On February 11, Commerce announced the start-up of the mineral processing
mini pilot plant for Ashram. During 2014, Commerce completed bench scale testing of the deposit and confirmed a mineral processing flowsheet that included a grinding circuit, a flotation circuit, a weak hydrochloric acid (HCl) leach to remove carbonate, and Wet High Intensity Magnetic Separation (WHIMS) to remove fluorite. The resultant mineral concentrate assayed 43.6% total rare earth oxide (TREO) with recoveries of 70.7%. A mini pilot plant is the next step to substantiate the Company’s flowsheet and the viability of its rare earth concentrate products. Commerce estimates that $1.2 million will be
required to complete downstream metallurgical work at Ashram, including the operation of the hydrometallurgical pilot plant portion...
A broad range of non-fuel metals and minerals are critical to the United States commercial manufacturing base, the US hopes for a transition to a green-energy economy, sustained innovations in the high-tech sector, and advanced weapons systems to allow our military to e!ectively fulfil its mission to protect the homeland and project American power around the globe.
As a result, access to critical and minerals and metals becomes a matter of national security. Given that, one would expect that formulating a coherent national mineral strategy to ensure such access would be a public policy imperative.
Rare Earth Elements in National Defense: Background, Oversight Issues, and Op...Rare Earths / Rare Metals
Members of Congress have expressed concern over U.S. acquisition of rare earth materials composed of rare earth elements used in various components of defense weapon systems. Congress may encourage DOD to develop a collaborative, long-term, well-thought-out strategy designed to identify any material weaknesses and vulnerabilities associated with rare earths and to protect long-term U.S. national security interests.
This bulletin looks at the ongoing changes in Chinese REE policies, and muses how this will affect western access to rare earths in the relatively short term. There is also a discussion of the developments in the world of niobium.
Rare Metals Report on Tantalum & Niobium by Jacob Securities (July 19, 2011)Rare Earths / Rare Metals
Luisa Moreno, Ph.D, Equity Research Analyst with Jacob Securities Inc. has released their premier research report on the rare metals tantalum and niobium. The report mentions the listed companies with clear exposure to tantalum and niobium. This includes Commerce Resources Corp. (TSXv: CCE), Noventa Ltd. (TSX: NTA) and Pacific Wildcat Resources Corp. (TSXv: PAW).
A new guide to niobium and tantalum has been published by the British Geological Survey (BGS) on its website. These little-known metals have some unique properties which make them essential ingredients in a wide range of products, from mobile phones to artificial hips. As commodity prices rise and access to some raw materials becomes more difficult, a small group of so-called ‘critical metals’ is causing particular concern. Niobium and tantalum are two of the most widely used metals on this critical list. Because of their unique properties and their essential role in the manufacture of steel and electronic capacitors, they are hard to substitute.
Supply concerns surrounding these metals have been heightened because illegal mining of niobium-tantalum ore (sometimes known as ‘coltan’) has been linked to conflict in some parts of Africa.
The newly-published Niobium-Tantalum Commodity Profile from the BGS provides a concise, authoritative and easy to understand guide to the origins, production and trade of these important metals. Andrew Bloodworth, Head of Minerals and Waste at the BGS said: “Our profile on niobium and tantalum is the latest in a much-respected series from the BGS on critical metals, including rare earths, platinum and tungsten. Its publication is timely as it follows the recent release of the report of the House of Commons Science and Technology Committee inquiry into Strategically Important Metals which calls for more understanding of the role of these metals in our economy”.
On Marhc 22, 2011, at the 2011 TREM (Technology & Rare Earth Metals Center) Conference, Diana Bauer from the US Department of Energy presented this Summary Brief on Critical Metals Strategy.
