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.
Based on a subsequent report in October 2010, estimate of total resources for blocked out, assayed and geologically inferred ore, the potential valuation for the eight mining claims is $6.
It is believed that an inferred ore resource could be calculated for the principal El Capitan deposit in this manner.
The primary objectives of the drilling program were to further develop the down dip extension and the southern extension of the ore body and to reclassify within the current open pit design, inferred ore tonnes to measured and indicated category for incorporation into the feasibility study.
Inferred ore within the pit has been significantly reduced to less than 1.
