Drilling by junior Ourominas Minerals (OMI-T) at its wholly owned, 190,000-ha Juruena vein gold property in Brazil’s Mato Grosso state has extended the project’s known zones of mineralization.
Since drilling began last August, more than 4,500 metres from 30 holes have been collared in the vicinity of pits hand-dug by garimpeiros within two parallel, north-south-Trending mineralized zones, dubbed West and East, that are connected in the north by an east-west trending Main zone. Ourominas has complemented its surface work with a 10,500-km airborne geophysical survey.
In the northern portion of the 750-metre-long West zone, the best results from drilling near the Dona Maria pit were: 3.5 metres (from 76.4 to 79.9 metres) grading 14.83 grams gold per tonne in hole 24; 0.5 metre (from 42.9 to 43.4 metres) of 3.91 grams in hole 25; and 3.5 metres (from 47.9 to 51.4 metres) of 11.39 grams in hole 26.
In the southern portion of the 2,200-metre-long East zone, the best results from drilling near the Capixaba I pit were: 3.1 metres (from 122.4 to 125.5 metres) grading 1 gram gold in hole 12; 1.61 metres (from 97.9 to 99.5 metres) of 102.6 grams (a value attributable to the nugget effect) in hole 13; and 6.1 metres (from 20.3 to 26.4 metres) of 1.35 grams in hole 23.
This spring, on nearby garimpeiro tailings, Ourominas is planning to conduct a test leaching program that will process material at the rate of 30,000 oz.
