The company said the enhanced mine plans, produced by AMC Consultants, demonstrate that production can be increased to match the planned processing plant capacity and used to underwrite the required servicing of proposed project debt financing for longer-term operations.
Mine plans based on the two pits are expected to produce about 19,000 ounces of gold over 20 months through processing of 30,000t of ore per month, generating an estimated margin of A$12.6m.
The project’s processing capacity currently supports a base case of 15,00tpm and additional capital expenditure on refurbishing and installing second ball mill is expected to facilitate a step up to 30,000tpm.
The company has also updated the resource model focusing on the areas of proposed open pit mining by increasing a proportion of the ore-body to an indicated level of confidence.
