Ora Banda spruces up Davyhurst plant, produces 14,312 ounces gold in September quarter
Link copied to
Ora Banda has continued to improve the performance of its Davyhurst plant, with a trial of 100% hard rock into the crushing circuit lifting throughput of the crusher to nameplate capacity of 1.2 million tonnes per annum.
Since August, crushed oxide product from a mobile crusher has been supplementing the installed crushing circuit to address issues with a higher percentage of oxide feed in the blend.
Gold production for August and September averaged over 5,300 oz per month – or 80% of the average annual budget production requirement per month.
The company is continuing to implement improvements to reach target production levels, with the total gold production for the September quarter of 14,312 oz gold (unreconciled).
Ora Banda Mining (ASX:OBM) is currently reforecasting annual production, noting the following operational improvements at Davyhurst:
Diamond drilling at the Golden Eagle underground mine intersected mineralised contacts where expected, according to the revised interpretation. But as gold grades and widths were not economic, mining at Golden Eagle is unlikely to be extended beyond January.
Ora Banda has received the final report from an independent engineering review of the Davyhurst processing facility by Ausenco, which found no fatal flaws with the facility.
But the report did note that production rates during ramp-up were negatively impacted by:
Whilst the conclusions and related recommendations are each material to the operation of the Davyhurst processing facility, Ora Banda said that all key recommendations are already in the process of being implemented or planned to be implemented.
The company says it’s aware of some interest in its recently disposed Mt Ida tenements and the lithium potential of those tenements, which was historically categorised as predominantly lepidolite and is challenging to process due to the increased reagent costs associated with impurity rejection.
Outside of the disposed tenements, Ora Banda retains extensive land holdings with known lithium occurrences which have also been categorised as lepidolite.
However, the company is currently gathering further samples for mineralogical testing to confirm the ratio of spodumene to lepidolite.
The three areas within Ora Banda’s 1,210sqkm landholding that are known to host lithium mineralisation are the Riverina mine, the Waihi pit, and the Gila deposit.
