CBH Resources has reported that recent scoping studies have confirmed the economic viability of its Panorama Project in Western Australia as a high grade underground mine.
Development of Panorama has been pursued to date as an open cut mine, however, the current review has demonstrated that the project economics will be substantially improved if Panorama is developed as a high grade underground mine. The mine will be a significant producer of copper and zinc which will be exported through Port Hedland.
The recent scoping study shows that an underground mine with a production rate of 600,000 tonnes per annum is capable of supporting an initial mine life of around 7 years at relatively high grades. By targeting ore at average grades of 2% copper and 6% zinc, the mine will produce approximately 185,000 tonnes of zinc, 70,000 tonnes of copper and 880,000 ounces of silver throughout its anticipated life.
The geology of the mineralization lends itself to a low cost sub level open stopping operation able to produce attractive operating margins. There is potential to extend the current reserve within the known Sulphur Springs ore body. In addition the nearby Kangaroo Caves deposit, with a Mineral Resource of 6.3 million tonnes at 3.3% zinc and 0.5% copper, is likely to provide an extension to the Panorama mine life.
CBH is in the final stages of completing its earn in from Sipa Resources, while work to quantify the underground mine reserve is expected to be completed in December. Current indications are that the required capital expenditure for the underground mine development will be approximately AUD 150 million based on a production rate of 600,000 tonnes per annum.
GR Engineering Services has been engaged to validate the project capital cost estimates with the work expected to be completed within two months.
