Preparing To Add Further Gold Riches To “Giant” Project
Wiluna Mining Corporation Limited (ASX: WMX) has defined Maiden Exploration targets for the East/West structures at the Wiluna Mining Centre in Western Australia.
The JORC Compliant Exploration Target defined for the East/West structures at the Wiluna Mining Centre is approximately 35Mt to 40Mt @ 4.5g/t to 7g/t for 5Moz to 7Moz of gold.
The Exploration Target potential does not pertain to a resource and is purely an indication of the potential of the Wiluna deposit beyond the current production areas and currently defined Mineral Resource.
In line with the company’s major ongoing resource and reserve development programme, drilling and geophysical work is planned over the next 1 to 5 years to systematically test these targets.
The total historical endowment of the East Structure ranges in gold grade from 5.05g/t Au to 6.93g/t Au for 4.23 million ounces gold, so the Exploration Target over similar dimensions and gold grade is expected to range between 18Mt to 22Mt @ 5g/t to 7g/t for a total gold target of between 3Moz and 4Moz.
The total endowment of the West Structure ranges in gold grade from 4.70g/t Au to 5.94/t Au for 2.76 million ounces gold, so the Exploration Target over similar dimensions and gold grade is expected to range between 15Mt to 17Mt @ 4g/t to 6g/t for a total gold target of between 2.2Moz and 3.0Moz.
The Exploration Target is derived from the seven target endowments that are calculated from the recorded production and the current 2.5g/t cut off resource.
The same size area for each lode was extrapolated down-dip to show the potential. The Exploration Targets are based on extensive historical mining and drilling data and resource estimates, extrapolated into poorly tested areas where very wide-spaced previous drilling shows the structures do persist at depth, in places at similar grades.
Previous drill holes, spaced several hundred metres apart, returned varying results, but are considered too broad-spaced to have properly tested for high- grade shoots that contain the bulk of ounces in the adjacent very large JORC-compliant resource and previously mined zones.
In early 2021, WMC has scheduled a 2-Dimensional trial seismic survey over the Wiluna main mineralisation to map the gold structures potentially to several kilometres below surface. If successful this will be followed up with a detailed 3- Dimensional survey over the entire Wiluna Mining Centre with a view to define drilling targets for future resource growth.
Wiluna Mining’s geological team has developed and ranked a pipeline of over thirty targets across the Company’s 1,600 sq. km of highly prospective and productive tenure.
