Drilling Confirms Extensive Vanadium-PGM Deposit at Largo's Maracas Project (Brazil) 07:30 EDT Wednesday, October 17, 2007
- 41 of 42 holes intersect significant Vanadium-PGM mineralization - Updated resource estimate in progress - Focus shifted to PGM exploration - Eleven additional holes completed on second target with results pending TORONTO, ONTARIO--(Marketwire - Oct. 17, 2007) - Largo Resources Ltd. (TSX VENTURE:LGO) is pleased to provide a further update on its exploration program in progress on the Company's 2,000 hectare Maracas Vanadium-PGM property located 250 kilometres west of Salvador, Bahia, Brazil.
To date, 45 diamond drill holes totalling 11,196 metres have been completed on the Gulcari "A" deposit in order to expand and upgrade the Vanadium-PGM mineralization and the previously announced inferred mineral resource of 15.0 million tonnes grading 1.37% Vanadium Pentoxide (V2O5) (see press release November 22, 2006). Results were previously released for 16 holes (see press releases May 22, 2007, June 19, 2007 and July 18 2007). Three holes were drilled for geotechnical and metallurgical purposes (FGA81, FGA84 and FGA85). Significant results for the remaining 26 holes are summarized in Table 1.
Highlights from the new results include:
- FGA73 - 40.0 metres true width at 1.62% V2O5 and 0.34 g PGM/t (0.24 g Pt/t and 0.10 g Pd/t) and 17.5 metres true width at 2.81% V2O5 and 0.59 g PGM/t (0.54 g Pt/t and 0.05 g Pd/t)
- FGA74 - 39.0 metres true width grading 1.86% V2O5 and 0.27 g PGM/t (0.24 g Pt/t and 0.03 g Pd/t) including 25.0 metres true width grading 2.15% V2O5, and 0.25 g PGM/t (0.21 g Pt/t and 0.04 g Pd/t)
- FGA77 - 17.9 metres true width grading 2.37% V2O5, and 0.25 g PGM/t (0.22 g Pt/t and 0.03 g Pd/t))
- FGA79 - 70.0 metres true width grading 1.60% V2O5, and 0.32 g PGM/t (0.26 g Pt/t and 0.06 g Pd/t)) including 38.0 metres true width grading 2.32% V2O5, and 0.43 g PGM/t (0.35 g Pt/t and 0.08 g Pd/t)
- FGA87 - 22.0 metres true width grading 1.82% V2O5, and 0.41 g PGM/t (0.19 g Pt/t and 0.22 g Pd/t))
- FGA89 - 59.0 metres true width grading 2.11% V2O5, and 0.26 g PGM/t (0.19 g Pt/t and 0.07 g Pd/t)) including 36.0 metres true width grading 2.40% V2O5 and 0.27 g PGM/t (0.20 g Pt/t and 0.07 g Pd/t)
- FGA95 - 65.0 metres true width grading 1.46% V2O5, and 0.21 g PGM/t (0.11 g Pt/t and 0.10 g Pd/t))
- FGA97 - 50.3 metres true width grading 1.83% V2O5, and 0.47 g PGM/t (0.28 g Pt/t and 0.19 g Pd/t)) including 29.3 metres true width grading 2.26% V2O5, and 0.50 g PGM/t (0.34 g Pt/t and 0.16 g Pd/t)
Andy Campbell, P.Geo., Vice President Exploration commented: "Of the 42 holes drilled to expand and upgrade the resource, only one hole did not intersect the magnetite-rich layer confirming the excellent continuity of the Gulcari "A" deposit. Twenty of the 42 holes returned intersections that significantly exceeded the average grade (1.35% V2O5) and average true width (25m) of the original deposit. The deposit, which now extends 400m along strike and to a depth of 300m, is still open along strike as well as at depth."
Largo President & CEO Mark Brennan commented: "We are delighted with the results of the drilling program which have exceeded expectations. The updated resource estimate, which is in progress, will form the basis for an expanded scoping study including PGMs. Engineering work on the metallurgy is also well advanced."
PGM Exploration
The Gulcari "A" deposit is part of a mineralizing system that extends for 8 kilometres across the property. Results from drilling of the deposit indicate that the PGM mineralization is related to the disseminated sulphides in the massive magnetite zone. The PGM mineralization is significant and consistent throughout the massive magnetite lens with a very high Pt:Pd ratio averaging about 4:1, which is a comparable ratio to the Great Dyke. Of particular interest is Hole FGA-80 which intersected 3.93 g Pt/t and 0.21 g Pd/t (4.14 g PGM/t) over 1.0m in a section with 3-7% sulphides but very low magnetite. This suggests in addition to the magnetite lens, there is excellent potential for outlining higher grade PGM mineralization that may not be directly associated with magnetite.
With drilling on the main deposit complete, exploration has now shifted focus to test other areas along the system including, from north to south, Nova Amparo, Sao Jose and Gulcari "B". Eleven (11) shallow drill holes totalling 1,952 metres have now been completed at Nova Amparo located 4 km to the north of Gulcari "A" to test for PGMs associated with a magnetite lens. The initial indications from this drilling are that there are more sulphides associated with the magnetite at Nova Amparo compared to Gulcari "A". Assay results are pending for these holes.
Additional work in progress includes geological mapping at a scale of 1:2,500 and geophysical (magnetics and induced polarization (IP)) surveys. The magnetic survey has been completed while the IP survey is approximately 60% complete and is expected to be finished in early November. The geophysical work is being directed by Dr. Chris Hale, P.Geo., consulting geophysicist and a Qualified Person as defined under NI 43-101.
Analytical work was carried out by SGS Minerals in Belo Horizonte, Brazil, an ISO 9001-2000 certified laboratory. Largo employs a systematic industry standard QA/QC program including standards, duplicates and blanks. Andy Campbell, 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 and has reviewed this press release.
