The government authority has given Petratherm's area, which includes the historical Golden Jacket Mine, highest ranking.
This tenement area covers a highly prospective ground position over a portion of the Bendigo Zone and extends west to cover a large strike continuance of 32 kilometres in the Golden Jack Fault that shows several important gold occurrences.

Notable historic mine occurrences
The Golden Jack Mine comprises a shallow small-scale shaft reef mine worked to 46 metres depth.
Total recorded production was 171.7 tonnes of ore which produced 1,385 ounces of gold.
Although only a small historical working, the grade is exceptional, running at an average of 250.1 g/t.
The Nine Mile Reef is a larger historical mine which was worked down to 131 metres depth and with 43,571 tonnes of ore mined, producing 16,236 ounces of gold with an average grade of 11.6 g/t.
Gravity surveying techniques
Very little modern exploration has tested the extents and depths of these historical gold reef systems but the use of gravity surveying techniques to locate prospective faults has been paramount in targeting areas for drill testing with the potential to new discoveries.
Fieldwork to begin
Petratherm is reviewing previous exploration results and processing geological and geophysical data in order to begin fieldwork once the tenement has been granted.
The company is also actively looking to increase its Victorian project holdings through purchase or joint venture.
A recent resurgence in interest in Victorian Goldfields largely stems from the success of Kirkland Lake Gold’s Fosterville operations.
Annual production at Fosterville is forecast to increase to more than 500,000 ounces in 2020 and exceed 570,000 ounces by 2021
