Largo Reports Additional Strong Platinum and Palladium Values From Maracas Deposit in Bahia, Brazil
TORONTO, ONTARIO--( April 24, 2007) - Largo Resources Ltd. (TSX VENTURE:LGO) -
- Hole FGA43 returned 9.0 metres grading 1.08 g Pt/t, including 4.00 metres grading 1.73 g Pt/t
- Interval values are as high as 4.24 g Pt/t over 1 metre
- All 10 additional holes sampled returned PGM values ranging from 0.42 g/t and 1.13 g/t over intervals of true thickness between 9.0 and 32.0 metres
Largo Resources Ltd. (TSX VENTURE:LGO) is pleased to announce that it has received additional strong and consistent results for platinum and palladium from its systematic sampling program of previous drill core drilled by Odebrecht and Caemi (CVRD). Significant results from this batch of 308 samples are summarized in Table 1. Highlights include:
- FGA43 - 9.00 metres grading 1.08 g Pt/t and 0.05g Pd/t including 4.00 metres grading 1.73g Pt/t and 0.07g Pd/t
- FGA23 - 9.00 metres grading 0.86g Pt/t and 0.42g Pd/t including 4.00 metres grading 1.14g Pt/t and 0.64g Pd/t
The systematic core sampling program of the previous drill core is designed to confirm the platinum group metals (PGM) values obtained during the initial due diligence process (see press release dated October 16, 2006). A total of 1250 samples have been collected from 36 drill holes of which this current release reports the results available from 308 samples in 10 additional drill holes. Results from the initial 455 samples in 10 holes were previously reported on March 20, 2007. All drill core from the previous work is stored on site and is in excellent condition.
All 10 additional holes sampled returned significant PGM values ranging between 0.42g/t and 1.13g/t over intervals varying in true thickness between 9.00 and 32.00 metres. Individual 1.0 metre sample intervals returned values as high as 4.24 g Pt/t.
Largo is also pleased to announce that Dr. Reid Keays has been retained to review and assist in the evaluation of the platinum and palladium mineralization at Maracas. Dr. Keays is a well known expert in platinum group element (PGE) geochemistry and the development of genetic models and exploration techniques for Ni-Cu-PGE sulphide deposits. He has worked on a wide range of ore deposits including platiniferous PGE horizons in the Bushveld, Stillwater and Great Dyke layered complexes, Ni-Cu-PGE mineralization associated with komatiites (Kambalda, Cape Smith Fold Belt) and the giant Sudbury (Canada) and Noril'sk Ni-Cu-PGE camps. Dr. Keays will be making an initial trip to the Maracas project in May.
As previously reported, platinum group metals values from the original due diligence program of a total of 123 samples in 8 drill holes indicate that in the magnetite-rich zone, PGM's average between 0.52g/t and 1.24g/t over widths of 4.00 metres to 20.00 metres with a Pt:Pd ratio of 4:1. The highest PGM values found thus far correlate with the high-grade vanadium-magnetite zone.
Andy Campbell, P.Geo., Vice President, Exploration commented: "The PGM results continue to be very significant and with a very high platinum-palladium ratio. Once all the sample results are received we will have sufficient data to allow estimation of a PGM resource for the deposit. We are also very pleased to have Dr. Keays assisting us in further evaluating the PGM's at Maracas. It is very possible that the PGM's may have been re-distributed from an original sulphide melt by a later stage hydrothermal event. If this is the case, there could be excellent potential for other areas of significant PGM mineralization; we have initiated petrographic and microprobe work to better understand the nature of the PGM mineralization and provide criteria to aid further exploration."
The Maracas deposit is hosted within lower sequence of gabbros and pyroxenites of the 2.64 billion-year-old, Jacare River mafic-ultramafic intrusion. This sheetlike linear intrusion extends for 70 kilometres along a north-south strike averaging about 1.2 kilometre in width. There are a number of striking similarities to the Great Dyke including age, rock types, platinum and palladium ratio and style of intrusion as well as host rock that it intrudes. The PGMs found thus far are associated with disseminated to massive bodies of titano-magnetite in pyroxenites. This massive, titano-magnetite mineralization at Maracas ranges from 2.0 to 90 metres in thickness with an average true width of 25 metres.
Analytical work was carried out by SGS Minerals in Belo Horizonte, Brazil. Platinum and palladium values were determined by fire assay technique with an ICP finish using a 30 gram-sample. Andy Campbell, M.Sc., P. Geo., Largo's Vice President of Exploration, is the Qualified Person responsible for the scientific and technical work for the program as defined under National Instrument 43-101.
