Sydney, Australia, Feb 27, 2012 - (ABN Newswire) - Gold Anomaly Ltd (ASX:GOA) is pleased to report that recent 3-D modelling of the maiden resource inferred ore body at the Nevera Prospect, Crater Mountain, PNG, has identified two vertically stacked irregular sub-horizontal sheets of high grade gold mineralisation within the resource.
Inferred ore adds about 17% to the resource, at a grade of 10 g/mt, containing 152K-oz Au.
The company has also reported that there is a block of 13,200 t of possible ore grading just over 9 g/t; another block contains 127,000 t of inferred ore of probably similar grade.
