LONDON, UK, May 2, 2013 /CNW/ - Afferro Mining Inc. ("Afferro" or the "Company"), the TSX-V (AFF) and AIM (AFF) listed exploration and development company, is pleased to announce metallurgy results for its iron ore project at Ntem, located in south west Cameroon.
- High grade concentrate ranging between 68.5% and 65.2% iron obtained from a grind size of 75µm to 150µm (P80), respectively
- Excellent mass recovery and iron recovery of 46.7% and 81.6% at 150µm, respectively
- Results obtained from pilot-scale tests (Low Intensity Magnetic Separation, "LIMS") of composite 15kg samples
- Testing designed to accurately reflect large-scale processing
- Marketable product with low deleterious elements
- Davis Tube Recovery ("DTR") tests on 125 samples show that an average 81.7% of iron is present as magnetite phase
- High level of consistency between LIMS and DTR testwork provides further confidence in LIMS results

Luis da Silva, Chief Executive of Afferro, commented:
"Ahead of the Mineral Resource Estimate ("MRE"), these excellent metallurgy results highlight the potential for a low-cost mining operation at Ntem, delivering a highly marketable iron ore product. Strategically located only 80km from the deep-water port being constructed south of Kribi, we believe that the economics of a small-scale operation at Ntem could be very exciting. We have now completed the first two phases of drilling at Ntem and we remain on track to complete the MRE and the infrastructure scoping study results during Q2 2013. We believe that Ntem could add significant value to our portfolio of assets, providing a potential low capex opportunity to enter early stage production generating cash flow to support our strategy to bring the large-scale Nkout iron ore project to production."
The magnetite banded iron formation ("BIF") samples had an average head grade of 37.3% iron ("Fe"), representative of the deposit at the Fe08 target at Ntem. The samples were all 15kg composite samples taken from core from four holes across the deposit. The LIMS testwork was completed at the SGS laboratory in Perth, Australia. The results are highly encouraging and are consistent with DTR and Davis Tube Wash ("DTW") testing. LIMS testwork is pilot scale and uses a low magnetic field strength. It is therefore more representative of bulk processing. The results show that at a coarse grind size of a P80 of 150µm a high grade concentrate of 65.2% iron is attained at high recovery rates with mass recovery of 46.7% and iron recovery of 81.6%. The product also has very low deleterious materials, with only 0.24% alumina ("Al2O3") and 0.01% phosphorous ("P") present. The silica ("SiO2") content ranges from 4.25% to 8.55% at grind sizes of 75µm to 150µm respectively.
The magnetite BIF samples had an average head grade of approximately 36% iron, with 125 composite samples being selected for DTR test work. Assay pulps from the fresh magnetite were used to produce 8m down-hole length composite samples. The DTR test work was completed at the SGS laboratory in Perth, Australia. The results are highly encouraging with a very high grade concentrate averaging 70.9% Fe, 0.08% Al2O3, 1.42% SiO2 and 0.002% P attained at an average mass recovery of 41.8%, at a grind size P80 of less than 45µm. The DTR results show that on average 81.7% of the Fe within the BIF relates to a magnetite mineral phase. As the DTR tests were conducted on samples from across the deposit, they add confidence to the results of the more specific LIMS data.
DTW test work was carried out on the same composite sample as used for the LIMS test work and was used to identify at which grind sizes the LIMS test work should be carried out. The testing was completed at the ALS laboratory in Perth, Australia. The data is shown below and there is a good level of correlation with the LIMS results.
