URU Metals Nickel Joint Venture UPDATE



South African Nickel Joint Venture Update
 Ongoing drilling continues to confirm large disseminated nickel resources at Burgersfort and Zebediela nickel projects, South Africa

Highlights

·    Additional drilling results from both the Burgersfort and Zebediela nickel projects confirm large open pit disseminated sulphide nickel resources. The first phase of drilling has now been completed on both projects.
·    URU Metals has satisfied the terms of the Joint Venture Agreement and has fully vested its interest in both projects.
·    The South African Nickel Joint Venture ("Joint Venture") has engaged MSA Group to complete a Preliminary Economic Assessment ("PEA") on the Zebediela Nickel Project. 
·    Appointment of Mike Houston as CEO of the Joint Venture.

Commenting on the nickel joint venture update, Paul Loudon, Non-Executive Chairman of URU Metals, said: "The results continue to be extremely pleasing and indicate that both Burgersfort and Zebediela host large open pit disseminated sulphide nickel resources. Furthermore, the economic potential of one of these projects, Zebediela,will be indicated with the completion of a PEA.  I am particularly pleased to announce that Mr. Mike Houston, a highly experienced mine builder has joined the team.  Mike will lead the feasibility assessments and development of the projects on behalf of the Joint Venture.

TAIA Lion Resources, Investing, Drilling, Developing

TAIA Lion Resources, one of Sierra Leone's leading gold and precious metals exploration companies, recently undertook a ten hole drill campaign across their Gori Hills gold exploration project. Targeting the N'Jama area cliff face, the company has reported results from just over six of the holes sunk along a north south strike. Assay results so far have been very positive, and the company is showing all the signs of being able to assemble a robust geological and data package that will go on to support the implementation of a pre-feasibility study. Commenting on the progress CEO Ari Untracht said, "I am delighted with the progress we have been making at Gori Hills, which comes off the back of the good results we delivered from our initial drill campaign at our other property at Lake Sonfon. Our Gori Hills property looks really promising and I am now quietly confident that TAIA, through the support of our wonderful shareholders, technical teams and our fantastic stakeholders in Sierra Leone, will be able to move up a gear and progress towards securing an internationally acceptable resource estimate on at least one, but ideally both of our properties. TAIA Lion is delivering on our commitment to be a good custodian of our exploration licences and work on them to swiftly move to realising our vision, which is to develop a world class gold mine that can make a considerable contribution to the economic development of Sierra Leone"

Brazilian Gold Corp BGC.TSXV, Superb Gold Recoveries of 88% to 92% from Recent Test-Work at Flagship São Jorge


Brazilian Gold reports Excellent Gold Recoveries of 88 to 92% from Preliminary Metallurgical Testwork for the São Jorge Deposit, Brazil

Brazilian Gold Corporation (TSXV: BGC) is pleased to report results for initial metallurgical testwork on representative composite drill-core samples of primary mineralization from the São Jorge deposit. The study was conducted by Testwork Desenvolvimentos de Processo Ltda., Nova Lima, Minas Gerais, Brazil. All samples were analyzed by SGS Lakefield Geosol Laboratórios Ltda., Vaspasiano, Minas Gerais, Brazil. 

Highlights include:
- 88 - 92% recoveries for direct carbon-in-pulp and carbon-in-leach cyanidation tests at P80 = 200 mesh (75 microns).
- Gravity recoverable gold of 40-50% at a concentrate grade of 25 g/t.
- Cyanide consumption of 0.32 kg/t.
- The mean calculated head grade for the range of tests carried out was 0.78 g/t, well below the diluted resource grade of 0.91 g/t. Brazilian Gold's metallurgical consultants anticipate an increase in recoveries at higher feed grades.


Samples were taken from nine drill holes, covering a strike length of 600 m over a vertical depth of 60 to 350 m below surface. The samples were crushed to P80 = 1.68 mm and composited into a single representative sample from which a number of 1 kg sub-samples were taken for leach and gravity recovery testwork.
São Jorge gold bearing samples have been shown to be amenable to cyanide leaching at a grind of P80 75 micron grind size. In bottle roll leach tests using this grind size, gold recovery was found to be between 88% and 92%.
Cyanide dosage optimization test work results indicated that cyanide consumption of 320 grams of cyanide per tonne of feed was required in order to achieve the highest gold recovery. 
Samples were also subjected to gravity concentration prior to cyanide leaching for which the average recovery was 41% at a feed size of 75 micron P80. The gravity concentrate assayed 25 g/t. Cyanide leaching of the gravity tails product reported gold recoveries between 88 and 92%. 
The free milling properties of the gold in the samples indicate that gravity concentration is viable, which should help gold extraction ahead of cyanide leaching resulting in lower cyanide consumption and shorter leach residence time.
Further testwork is planned to better define grind size versus gold recovery and to optimize leach residence time and cyanide consumption rates. Additional work will also include intense cyanide leach recovery potential of the gravity concentrate for its impact on overall gold recovery.
Ian Stalker, CEO of Brazilian Gold, commented "These results add further significant value to our ongoing work on our São Jorge project in the Tapajós region of Brazil. The metallurgical testwork has determined that gold recovery in the 90% range is possible, confirming estimations made in the PEA delivered in July 2011, and we can expect better recoveries at our predicted higher feed grades when operations commence. The ability to separate and recover gold by gravity indicates lower capital and operating costs can be expected.

As indicated by our consultants, the mean calculated head grade for the range of tests carried out was 0.78 g/t gold, well below the diluted resource grade of 0.91 g/t. Brazilian Gold's metallurgical consultants anticipate an increase in recoveries at higher feed grades.

Based on the results, consideration will also be given to a 'heap leach' approach to treating our ore body.
It is also important to note our ongoing optimization of the São Jorge project by Coffey Mining (Canada) following completion of the 2011 drill campaign. The mining inventory recovered from the resource reported in the July 2011 PEA was only 49% and any further increase in the reserve will add extra dollar value to our project."
