Paddys Flat Development
- Prohibition zones confirmed
Drilling, primarily designed for geotechnical, resource model validation and
metallurgical testwork purposes, has validated the geological model constructed
and recorded intercepts better than predicted by the model.
The Paddys Flat development plan envisages a conventional 5 metre x 4.5 metre
decline development to exploit a resource of 635,000 tonnes at 8.0 g/t for
162,500 ounces. The majority of the decline and lateral development is
positioned in the competent banded iron formation host of the Prohibition
orebody.
As an integral component of the definitive planning process, three holes have
been completed into Prohibition principally to finalise mining, and process
design parameters for the partially refractory ore.
The current Prohibition resource extends 70 metres vertically and 100 metres in
a southerly down plunge direction below the 120 metre deep open pit.
Intersections recorded to date (shown on the table below and diagram at http://
www.stbarbara.com.au/UPLOADED/SBM000402.pdf) are on average 20 percent higher in
gram-metres than model predictions.
A 13 hole (4,400 metre) RC drill programme down plunge is planned for October
2003.
Notwithstanding that these results need to be fully evaluated, the potential for
a technically and economically viable operation at 30,000 tonnes per month
remains on plan for the 2004/05 production schedule.
