Rare earth prices slight fluctuations this week, mainly light, lanthanum, cerium, yttrium oxide market transaction price down. Praseodymium, neodymium, gadolinium alloys and oxides of market prices remained strong.

The gradual increase in the supply of foreign markets, has also been the resumption of production in the domestic Big Three, small and medium-sized enterprises have been looking for goods shipped in the traditional sales season in March, the market gradually active signs. Deserted February, March, manufacturers and trade slightly busy. No matter the market inquiry how lively, the industry is more than reflect, the market traded just slightly better than February, "high season" yet arrived. As far as we know, the rare earth hold stocks and more depending on the purchases and sales of inventory and the market price of some products, such as the current market oxide, praseodymium, neodymium, gadolinium oxide recent inquiries and procurement increased, the price steady bullish. Of neodymium oxide, erbium, yttrium Inquiries less cargo operators who offer slightly downstream. This week the lanthanum cerium class oxides turnover in general, the transaction price is lower than in February. Oxide, europium, terbium market turnover less stable, offer basic.

Alloy market such as praseodymium, neodymium, gadolinium-ferrous market tax price of basic remain unchanged, and individual cargo operators to raise its offer, and also not too out of the mainstream of the market price, the gadolinium iron prices slightly upstream excluding tax, dysprosium iron prices this week basically stable.

Cavan Ventures Inc. is pleased to announce that it has been granted an option to acquire four prospective new mining properties covering graphite occurrences and with a potential for rare earth elements.

The four properties are located in Quebec, Canada, and are all easily accessible by paved or gravel roads and close to infrastructures.

The Pierre Riche North and South claims are located at about 130 km southwest of Saguenay-Chicoutimi, and about 70 km north-northwest of La Tuque. The Trans Canadian railroad line used by the Canadian National Railroad passes just 45 km south of the claim groups.

Pierre Riche North comprises 31 map-staked claims covering 1,705 hectares (4,213 acres). The property covers granitic gneiss, anorthosite, calcsilicate rocks, paragneiss and metasediment. Mafic gneisses contain disseminated sulphides and pockets of pyrite and graphite. Historically, the graphite flakes were mistaken for molybdenite. Anomalous values of copper, nickel, zinc, vanadium and manganese were obtained from a 0.80 m long channel sample.

Pierre Riche South comprises 11 map staked claims covering 605 hectares (1,495 acres), with the same lithologies as on the North claims. Anomalous values in copper, nickel, manganese, strontium and barium were obtained from one-meter long channel samples. This property presents an excellent potential for graphite in flakes and rare earth elements in pegmatite and mafic gneiss.

Two additional mining properties are located in the Upper Gatineau River region in the western part of Quebec, and about 70 km south of the Company’s Pythonga Lake Rare Earth Element project.

The Cawood and Saint-Marie properties are located at about 65 km north of Ottawa, and accessible by paved roads. Infrastructure in this region is excellent for a mining operation. Cawood comprises 10 map staked claims covering an area of 550 hectares (136 acres). This property has potential for graphite, mica, apatite and rare earth elements. It is located in the Maniwaki Metasedimentary Basin, well known for its graphite deposits and base metal occurrences (Pb-Zn) associated to calcitic and dolomitic marbles. In the past, numerous small graphite occurrences were mined by open-pits which are still accessible.

The Sainte-Marie property comprises 11 map staked claims covering an area of 605 hectares (1,495 acres). Several graphite occurrences exist on the property and there is also potential for rare earth elements. Six graphite occurrences were studied during a mapping program. Most have returned values higher than 3% graphite in quartz-feldspar gneisses of the H Unit. One occurrence returned 25% graphite over one meter in a shear zone.

The four mining properties were acquired from three well-renowned prospectors. CAVAN can earn a 70% interest in the four mining properties by issuing the optionors a total of 1,500,000 shares over a period of two years and making two cash payments totalling $35,000 of which $15,000 is payable upon signing. The Company must spend a minimum of $60,000.00 during the first year of the agreement. Claims are subject to a 2% net smelter return of which the Company may buy back 1% for the sum of $1,500,000 and has the first right of refusal to purchase the balance of the royalty as well as the remaining 30% interest. The acquisition of the claims is subject to acceptance by the TSX Venture Exchange.

Peak Resources Limited reported further improvements to beneficiation processes for the Ngualla Rare Earth Project in Tanzania. The ability to concentrate mineralisation at an early stage prior to acid leach recovery will have a significant and positive impact on costs and support Peak’s target to be a low cost producer.

The optimisation of the beneficiation process effectively reduces the mass of feed to be treated by the acid leach recovery process by 43% compared to the scoping study assumptions. This will lead to significantly lower capital and operating costs for the operation.

The latest test work shows that conventional magnetic separation and flotation techniques reduce the mass of the feed mineralisation by 78% through the rejection of relatively unmineralised barite and iron oxides.

Reducing the amount of material processed at the acid leach recovery stage has a significant impact on operating costs by reducing sulphuric acid consumption – the major constituent of reagent costs. The scoping study completed in early December 2012 estimated that the acid plant and acid leach recovery circuit make up 53% of total operating costs.

The reduction in volume treated will also reduce capital costs as a smaller plant will be required for the same amount of product. The acid leach recovery circuit and the acid plant together constitute 27% of total project capital costs as estimated in the scoping study.

The beneficiation process increases the grade of the feed over 3 fold from 5.3% REO* to 16.9% REO for this composite sample.

The cost reductions will be quantified in a revision of the scoping study and economic assessment to be completed in Q2 2013. The revised study will also use a new optimised mine schedule based on the new Mineral Resource estimate and model that is on schedule for completion by the end of March 2013.

Peak Resources Managing Director Richard Beazley said “Ngualla continues to improve with each milestone. We are already in the lower quartile in terms of operating costs, and also have one of the lowest capital costs of any rare earth project. This new test work will allow us to reduce costs even further and supports our assertion that Ngualla is the most commercially attractive rare earth project around.”

Why do some people take a risk to extract rare earth illegally? And what impacts will illegal extraction bring to the environment and residents nearby?

This area began rare earth extraction since some time between May and June last year, according to people living in the neighbor. The illegal work site cover an area of 4 to 5 acres,there are physic permeating separation pool and reaction pool, where fills with acid liquids like oxalic acid, semi-finished product of extracted rare earth was put nearby. Exhausted gas and liquid generated by chemical reaction are actually been discharged directly, red liquid can be detected everywhere is some cannels in lower reaches. Residents complain that vegetables have been polluted.

It is said that, the extraction of rare earth is rather complex, besides, the content of rare earth is quite small in raw ores. Even though, rare earth is a kind of material that is of strategic importance to a country, in addition the price of rare earth is very high, that is why many people will take risk to extract rare earth secretly. But the extract consumes a large number of water. To make it easier to get water and exhaust waste water, work sites are usually located near water source or reservoir.

Dr. Wen of Applied Chemistry Department , Shenzhen University said that waste water exhausted after the extraction of rare earth contains acid and waste residue which are toxic and could be harmful to peripheral environment.
